Description

Description Sanitary ware technical field

The present invention relates to a sanitary product that can stably maintain a worn state between labia. Background art

Conventionally, sanitary napkins and tampons have been commonly used as feminine sanitary products. Here, with regard to sanitary napkins, great efforts have been made to prevent menses from leaking through gaps due to poor adhesion near the vaginal opening. In addition, tampons also have a great deal of effort to eliminate foreign substances when wearing them, as well as discomfort and difficulty in wearing them in the vagina, due to the attributes of the articles. I have. .

Under these circumstances, an interlabial pad to be worn between the labia has recently attracted attention as a sanitary product located between a sanitary napkin and a tampon.

Since this interlabial pad is worn sandwiched between the labia of women, it has higher adhesion to the body than sanitary napkins, so it is difficult for menstrual leakage to occur, and it is also used for tampon inserted into the vagina. It has the characteristic of lower psychological resistance when worn.

However, when the amount of menstrual blood is large, the interlabial pad sandwiched between the labia may be pushed out from the inside of the labia with menstrual blood flowing along the inner surface of the labia to the outside of the labia, and in such a case, As a result, menstrual blood leaks without being absorbed by the interlabial pad. There was a problem that it would.

Another problem is that it is not easy to mount the interlabial pad at an appropriate position between the labia that are difficult to see.

The present invention has been made in view of the above-described problems, and an object of the present invention is to stably attach the interlabial pad worn between female labia without adversely affecting the labia. It is to provide a sanitary product that can be maintained.

It is another object of the present invention to provide a sanitary product that allows easy and accurate mounting of the interlabial pad. Disclosure of the invention

In order to solve the above problems, in the present invention, the interlabial pad is held at a predetermined position in the labia by pushing up the interlabial pad with an elongated member that can be fixed to underwear or an absorbent article. It is characterized by being able to do.

In addition, it is a composite sanitary product that can hold the interlabial pad in a predetermined position in the labia by restraining the sheet body that can be fixed to the underwear via a connecting sheet having elasticity and elasticity. And '

Another feature of the composite sanitary product is that the interlabial pad can be mounted at an appropriate position in the labia while confirming the mounting position using the fingertips.

More specifically, the present invention provides the following.

(1) An interlabial pad mounting aid used when mounting an interlabial pad having a size and a shape that can be easily sandwiched between labia, and underwear worn by a wearer Alternatively, the undergarment or the absorbent material so as to form a suspension bridge from the front to the back of the absorbent article In the wearing state, the interlabial pad is supported from the opposite side of the body in order to stably fix the interlabial pad between the labia, and An interlabial pad mounting aid, comprising an elongated member for urging the interlabial pad toward the body. .

According to the invention of (1), the initial state in which the interlabial pad is sandwiched between the labia by using the interlabial pad mounting aid (hereinafter simply referred to as an auxiliary tool) in combination with the interlabial pad is used. Can be maintained stably. That is, the assisting device according to the present invention is provided so as to be located on the opposite side of the interlabial pad from the front body to the back body of the underwear, or at one end in the longitudinal direction of the vertically long absorbent article. From the other end. For this reason, when such an auxiliary device comes into contact with the interlabial pad by lifting the undergarment of the wearer, a catching device that is generating tension in the part that is in a suspension bridge shape for the undergarment or the absorbent article, The interlabial pad sandwiched between the labia is pushed up strongly toward the labia. Pushing up of the interlabial pad by this assisting device can fix the position of the interlabial pad between the labia and maintain the initial state of wearing.

In the present invention, since it is only necessary that the assisting device can push the interlabial pad up toward the wearer's body, it is not necessary to positively fix the assisting device and the interlabial pad with an adhesive or the like. Here, when the interlabial pad is not fixed to the assistive device, the interlabial pad is sandwiched between the labia, and the assistive device is attached so as to be fixed to the underwear.

In this specification, the “long member” may be any member that can be attached in a suspension bridge shape from the front to the back of the underwear or the absorbent article at the time of attachment, and in addition to a series of sheets, a band, a band, and the like. Various objects such as shapes and threads can be used. Also, in this specification, the `` front '' of the underwear or the absorbent article refers to a portion located near the pubic bone of the wearer when worn, and the `` back '' is located near the buttocks of the wearer when worn. Part.

(2) The elongated member has elasticity, and in a wearing state, the interlabial pad is urged by the restoring force of the elongated member. Auxiliary device for wearing the interlabial pad.

According to the invention of (2), the interlabial pad mounting auxiliary device (hereinafter simply referred to as an auxiliary device) has elasticity. For this reason, when the assisting device comes into contact with the interlabial pad during wearing, a restoring force is generated to return to the original state before the wearing by the elastic stretching force of the capturing device itself. It is possible to more stably maintain the fitted state of the interlabial pad in the labia than in the case.

(3) An interlabial pad of a size and shape that can be easily sandwiched between the labia and has a substantially longitudinal shape having a longitudinal direction and a transversal direction, and is worn by a wearer. The undergarment or the absorbent article includes an elongated member attached to the undergarment or the absorbent article so as to form a suspension bridge from the front to the rear of the absorbent article. In order to stably fix the interlabial pad between the labia, the interlabial pad is supported from the opposite body side or both ends in the longitudinal direction of the interlabial pad, and the interlabial pad is directed toward the wearer's body. An interlabial pad with a mounting aid, characterized in that the pad is biased and serves as an interlabial pad mounting aid.

According to the invention of (3), the interlabial pad and a wearing aid for assisting the wearing (hereinafter, simply referred to as an assisting tool) are integrated. For this reason, the gap between the interlabial pad and the assistive device is prevented before and after the interlabial pad is attached, and the fitted state of the interlabial pad between the labia is made suitable and reliable. be able to.

In addition, since the interlabial pad can be positioned at the center of the assistive device, the interlabial pad can be positioned more securely at the center of the wearer's inner thigh than in the case of (1). Become.

(4) The elongated member has elasticity, and in a wearing state, the interlabial pad is urged by a restoring force of the elongated member. (3) Interlabial pad with an assistive device for wearing.

According to the invention of (4), the wearing aid provided in the interlabial pad (hereinafter simply referred to as an assisting tool) has elasticity. For this reason, at the time of wearing, a restoring force is generated by the elastic expansion and contraction force of the assisting tool itself to return to the original state before the wearing, and the interlabial pad in the labia is more reliably than in the case of the above (3). Can be stably maintained.

(5) A support sheet body made of a material that deforms to some extent, an interlabial pad body of a size and shape that can be easily sandwiched between the labia, and this interlabial pad body and the support sheet And a stretchable connecting sheet for connecting the body and the body, and in a state before wearing, the support sheet body has an arcuate shape and the interlabial pad body is supported in a hollow state; and In the wearing state, the interlabial pad body is urged toward the labia of a wearer by the restoring force of the connection sheet body.

According to the invention of (5), the interlabial pad body sandwiched between the labia and attached is fixed in the labia at the time of wearing by the deformation of the support sheet body and the restoration of the connection sheet. That is, the support sheet body, which has been bowed before being attached, is deformed to follow the shape of the underwear by being attached to the underwear. With the deformation of the support sheet, the connecting sheet joined to the support sheet is supported by its elasticity and elasticity. It is temporarily stretched by pulling from the toss body and becomes taut. Then, after the support sheet is attached to the underwear, a contraction force for returning to the state before the extension is generated in the connection sheet due to the elasticity of the connection sheet.

Then, when the wearer pulls up the underwear to which the support sheet body is attached, the labia are strongly pressed against the interlabial pad body. As a result, a force (reaction force) toward the clothes is generated from the labia to the connection sheet on which the interlabial pad body and the interlabial pad body are attached, but the connecting sheet has elasticity and elasticity. Therefore, a force repelling this reaction force is generated. This repulsive force is the “push-up force” that pushes the interlabial pad body up against the labia.

In this way, a restoring force is generated by the elastic stretching force of the connection sheet to return to the original state before the connection sheet was attached, and the fitted state of the interlabial pad body in the labia is stably maintained. It is.

In this regard, the interlabial product disclosed in U.S. Patent No. 6,033,391 (see Figures 26 and 27) has an upper part facing the vestibular floor of the wearer. Absorbent body that consists of a lower part that protrudes in the opposite direction to the vestibular floor of the wearer and an upper part of the absorbent body that contacts the inner surface of the labia when worn The extension portion 124 is joined so as to protrude downward and outward, and furthermore, a biouniform adhesive 125 (refer to FIG. 26) is attached to the labia contact surface of the absorbent flexible extension portion 124. (Shaded area) is applied.

Here, menstrual blood discharged from the vaginal opening generally flows to the vulva through the vestibular floor or the inner surface of the labia, but the route changes according to the amount of excretion and behavioral changes of the wearer. The moist environment inside the labia, including the mucous membranes, also varies greatly depending on the wearer's constitution and health.

In this regard, the above conventional interlabial product uses a biocompatible adhesive 125 The inner surface of the labia 1 2 ′ 3 and the absorbent flexible extension 1 2 4 enhance the adhesion between the labia and the interlabial product, which is affected by the above-mentioned changes. It is considered possible to reduce the risk that the interlabial product will fall out of the labia without causing any problems.

However, the interlabial space, including the vestibule floor, is a delicate site with a very low barrier function that protects foreign objects. For this reason, the biocompatible adhesive 1 25 has a risk of developing a rash due to rash depending on the constitution of the wearer. In addition, when the impact received by the change in the behavior of the wearer is transmitted to the absorbent flexible extension 124, or during the operation of removing this interlabial product from between the labia, the adhesive force of the adhesive causes the inner surface of the labia There is also a risk of scratching and scratching.

Further, when the above interlabial product is worn between the labia, a biocompatible adhesive

1 2 5 may touch the vicinity of the labia and be adhered to a position different from the position assumed by the wearer.In such a case, it is very difficult for the wearer to repair it. It may cause inconvenience of struggling.

In addition, when the position of the interlabial product once worn between the labia is displaced due to friction of underwear or sudden movement of the body, the biocompatible adhesive 1 25 The interlabial product is fixed, and the interlabial product tends to stabilize at the position where it has shifted without returning to the original optimal position. In such a case, it is difficult to sufficiently exert the function of preventing menstrual blood leakage to the outside.

In this regard, in the present invention, the interlabial pad body sandwiched between the labia is maintained in a mounted state by the connecting sheet and the support sheet body joined thereto, and the biocompatible adhesive is provided as in the above-described conventional example. Even without the use of an agent, displacement of the mounting position between the labia is prevented. This Therefore, the interlabial pad body is prevented from falling off from between the labia without adversely affecting the body.

(6) a body side that is of a size that can be easily sandwiched and held between labia and has a substantially vertically long shape having a longitudinal direction and a transverse direction, and is oriented to the body side; An interlabial pad body capable of absorbing bodily fluids, the antilabial pad body having an anti-body side surface oriented to the clothes side; and a non-body side of the interlabial pad body arranged so as to come to a position overlapping the interlabial pad body. A substantially longitudinal shape having a direction and a lateral direction, wherein the major axis along the longitudinal direction has a dimension longer than at least the major axis along the longitudinal direction of the interlabial pad body. A support sheet body having a body side face oriented toward the side and a body side face oriented toward the garment side; and the support sheet having a restraining property for restraining the interlabial pad body at the overlapping position. Connected to the body and oriented toward the body A connecting sheet comprising: a body side to be worn and an anti-body side oriented to the clothes side.

According to the invention of (6), the interlabial pad body which is closely interposed between the labia and directly absorbs menstrual blood is restrained by the connecting sheet joined to the support sheet body at a position overlapping the support sheet body. ing. For this reason, in a natural state before wearing, the interlabial pad body is positioned on the support sheet body so as to float in the air.

According to the present invention, the connection sheet is stretchable, but the elastic extensibility is such that the connection sheet expands and contracts at least in the same direction as the longitudinal direction of the interlabial pad attached to the connection sheet. Is preferred.

When the composite sanitary product according to the present invention is worn, the joint (front base point) between the support sheet body and the connection sheet located in front of the wearer's body at the time of wearing is placed from the wearer's front labia commiscia. The joint between the support sheet and the connecting sheet, which is located forward and behind the wearer's body when worn (Base point of the rear end) is located behind the rear labia commiscia of the wearer. By doing so, between the front end base point and the rear end base point, the connecting sheet is curved to lift the interlabial pad body interposed between the labia, and the interlabial pad body is lifted. This can reduce the risk that the interlabial pad body will fall off from between the labia due to the force exerted on the connecting sheet to push it up toward the body.

The part where the two labia majora join before and after the cleft is called the anterior labia commiscia, where the upper margin of the pubic connection joins, and the part where the perineum reaches the perineum Is called "posterior labia commiscia".

'Although the interlabial pad body and the support sheet body are mutually restrained, they have a certain degree of freedom due to the interposition of the connecting sheet, and each can be deformed within a certain range. Therefore, even when the support sheet body is deformed, the interlabial pad body is not immediately deformed in conjunction with the deformation, and the state of being sandwiched between the labia can be suitably maintained.

In addition, by applying an adhesive to the side of the clothes of the support sheet body, the clothes and the support sheet body are fixed via the adhesive at the time of wearing, and the support sheet body is mounted in the clothes. Positional deviation can also be reduced. This makes it possible to indirectly fix the interlabial pad body.

Further, in the present invention, since the support sheet body is positioned so as to overlap the opposite side of the interlabial pad body, the support sheet body is made to have absorptivity, so that the labia Menstrual blood that could not be completely absorbed by the pad body can be received by the support sheet body and absorbed.

In order for the connecting sheet of the present invention to have elasticity, In addition to the body being made of elastic elastic material, it can be made of a combination of elastic elastic material and non-elastic elastic material that join the elastic elastic material to the inelastic elastic material in the stretched state, or a fibrous sheet made of elastomer resin. There is a method of constructing it with a film sheet.

When joining the connecting sheet to the support sheet body, it is preferable to join the connecting sheet so that the connecting sheet extends from one end to the other end in the longitudinal direction of the support sheet. As a result, even when the support sheet body is attached to the underwear and extended toward the underwear, a restoring force for returning to the original state is generated by the elastic force of the connection sheet. For this reason, it is easy to maintain a linear state even with a force applied from a direction other than the extension direction, and the restoring force of the connecting sheet generated at the time of wearing, lifts the interlabial pad body in the air and lifts the interlabial pad body. This is a force that pushes up toward the body, and can prevent the interlabial pad body from falling off the labia.

In addition, since the connection sheet has elasticity, it is possible to flexibly change its form, such as by tilting the interlabial pad body, which is mounted on the connection sheet in a convex shape, sideways. It is very convenient when doing.

In the present invention, when the connecting sheet is joined to the support sheet body so as to be in the stretched state, the connecting sheet is stretched and joined to the support sheet body in the normal state, and the support sheet body is normally bent. It is possible to adopt either of the following methods: joining to the connection sheet in the state, and (3) slightly extending the connection sheet and slightly bending the support sheet body to join them together.

In this specification, “oriented” means that the orientation is arranged in a predetermined direction. In this specification, “overlap” means “dense”. This does not mean only the state of wearing and overlapping vertically, but also the state of being arranged at the same position through a certain space.

(7) The bending rigidity value in the longitudinal direction of the support sheet body is 0.5 to 20 mN / 25 mm, and more preferably 1.5 to 10 mΖ25 mm. Features, and the composite sanitary article according to (6).

According to the invention of (7), the bending stiffness value of the support sheet body is such that when the composite sanitary product is mounted, the support sheet body is deformed toward the clothes and the pushing force to the body side of the connection sheet, In other words, the bending stiffness value has a resilience greater than the restoring force and the equilibrium state with respect to the restoring force of returning to the original shape of the connecting sheet. This makes it possible to sexually lift the interlabial pad body when wearing the composite sanitary product.

At this point, if the bending stiffness value is less than 0.5 m NZ 25 mm, the support sheet body peels off from the underwear because the resilience of the support sheet body is less than the restoring force of the linked sheet. As a result, the linear distance between the starting point of the front end of the connecting sheet and the starting point of the rear end of the connecting sheet is shortened, which results in a slack state in which it is difficult to convert the restoring force of the connecting sheet into a pushing force toward the body. . This not only prevents the interlabial pad body from falling off between the labia, but also causes the interlabial pad body to fall out of the support sheet body, and further to the underwear, and the interlabial pad body and the connecting sheet body In the extreme case, the entire composite sanitary product including the support sheet may fall out of the underwear.

On the other hand, if the bending stiffness value is larger than 20 m NZ 25 mm, not only may the interlabial pad body not easily follow changes in the wearer's movement, which may cause discomfort to the wearer. However, there is a danger that the support sheet body will not easily follow the change in the underwear's expansion and contraction, and the support sheet body will easily peel off from the underwear. In the present invention, the configuration of the support sheet body is not particularly limited as long as it is a support sheet body that shows the range of the above-described bending rigidity value. For example, an elastomer component, a foam such as foamed polyethylene, or the like may be used alone. In addition, there may be mentioned those in which elastic blends as required are continuously arranged in the longitudinal direction, and these elastic stretches may be used alone or in combination with an absorber or the like.

The bending stiffness value in the present invention was measured using a Gurley flexibility tester manufactured by Yasuda Seiki Seisaku-sho, Ltd.

(8) The composite treatment article according to (6) or (7), wherein the connection sheet is joined to the support sheet body in an extended state.

According to the invention of (8), the connection sheet having elasticity and stretchability is attached in an extended state with respect to the longitudinal direction of the support sheet body. For this reason, when the connecting sheet is attached to the support sheet in a non-stretched state, the restoring force of the connecting sheet repelling the pulling force on the connecting sheet generated when the supporting sheet is attached to the underwear and deformed. It will be strengthened in comparison with.

As a result, the force to push the interlabial pad body toward the body side, that is, the interlabial pad body connected to the support sheet body via the connecting sheet is affected by the deformation of the sabotic sheet body. Thus, the force for preventing the falling off from between the labia can be reliably and more firmly generated in the connecting sheet.

(9) The connection sheet is made of an elastic stretchable material, or is formed by partially including an elastic stretchable material, and the elastic stretchable material has a stretch ratio of 105% to 180% with respect to a normal state. (6) characterized in that it is attached to said support sheet or connecting sheet in an extended state. (8) The composite sanitary product according to any one of the above (8).

According to the invention of (9), the connection sheet includes the elastic elastic member as a constituent element, and the elastic elastic member is attached in a stretched state at a predetermined expansion ratio. Here, when the connecting sheet is formed by joining the elastic elastic member in the stretched state to the non-elastic elastic member, the elastic elastic member is joined to the non-elastic elastic member at the above-mentioned stretching ratio, and the entire connecting sheet is formed. In the case where is made of an elastic stretchable material, the elastic stretchable material, which is a connecting sheet member, is joined to the support sheet body at the above-described stretch ratio.

If the elasticity of the elastic elastic material is less than 105%, the pad between the labia and the attached interlabial pad body in the mounted state has a weak push-up force against the force of falling off in the direction away from the body. However, it is difficult for the interlabial pad body to be elastically lifted.

On the other hand, if the stretching ratio of the elastic elastic material is more than 180%, a pushing force to the body side is generated more than necessary, which may cause discomfort to the wearer.

In this regard, according to the present invention, according to the present invention, it is possible to maintain an extended state sufficient to push up the interlabial pad body, which tends to fall off from between the labia, to the body side. ing.

Further, the strength of the extended state can be maintained at a level that does not cause a situation in which the interlabial pad body is unnecessarily pushed up toward the wearer's body side to make the wearer feel uncomfortable. For this reason, it is possible to make the state in which the interlabial pad body is sandwiched between the labia preferable for the wearer.

The stress of the elastic elastic member at the elongation ratio in the present invention is 5 to 100. It is preferably in the range of 1 ^ _25111111, more preferably in the range of 20 to 80 cN / 25 mm. (10) The ^ i-tie sheet is made of a water-permeable material, and the interlabial pad body is attached to a side of the connection sheet opposite to the body, (6) to (9). Or a composite sanitary article according to the above.

According to the invention of (10), since the interlabial pad body is attached to the opposite side of the body of the connection sheet, the interlabial pad body is arranged between the connection sheet and the support sheet body. Become. For this reason, the buffering of the elastic stretching force of the connection sheet due to the thickness and density of the absorber constituting the interlabial pad body is reduced.

Here, the joining between the connecting sheet and the interlabial pad body is preferably performed along the longitudinal center line of the interlabial pad body. Further, it is preferable that the bonding range is such that the bonding ratio to the connection sheet with respect to the apparent plane area of the interlabial pad body from the body side is 2 to 20% or less.

By performing the above-described bonding, the degree of freedom of movement of the interlabial pad body and the connection sheet is increased, and the interlabial pad body can freely move to some extent without being largely influenced by the movement of the connecting sheet. It will be attached to the connecting sheet in a state where it can be performed. As a result, the interlabial pad body has a so-called play portion that does not directly follow the movement of the connecting sheet.For example, when an impact is applied to the interlabial pad body that covers the vulva, Even when the position of the connection sheet is displaced relative to the body due to the movement of the wearer, the impact and the displacement are less likely to be transmitted to the connection sheet. Therefore, it is possible to maintain the adhesion between the inner surface of the labia and the pad body between the labia.

(11) The connection sheet is joined so as to extend from one end in the longitudinal direction of the support sheet body to the other end, and the interlabial pad body is attached to a side surface of the body of the connection sheet. The composite sanitary article according to any one of (6) to (9), wherein According to the invention of (11), the connection sheet is attached to both ends in the longitudinal direction of the support sheet body, and the interlabial pad body is attached to the side of the body of the connection sheet. For this reason, the connecting sheet can be composed of a series of sheets, and the manufacturing process can be simplified.

(1 2) The composite sanitary article according to any one of (6) to (11), wherein the interlabial pad body is provided with an elastic elastic material along a longitudinal center line thereof. .

According to the invention of (12), the elastic elastic member is attached to the interlabial pad body. As a result, the interlabial pad itself acts to push up to the body side, which increases the pushing force to the body side in addition to the pushing force of the connection sheet. This makes it possible to further improve the adhesion between the interlabial pad body and the vestibular floor in the labia where the interlabial pad body contacts along the longitudinal center line thereof.

(13) The interlabial pad body has both ends in the longitudinal direction joined to the connection sheet, and both sides in the short direction are not joined to the connection sheet. The composite treatment article according to any one of (10) to (12), wherein the composite treatment article is a finger insertion opening through which a finger can be inserted.

According to the invention of (13), the finger insertion port is formed between the interlabial pad body and the connection sheet. For this reason, a finger can be inserted into such a finger insertion opening, and only the interlabial pad body can be fixed to the fingertip and worn between the labia. Here, in the composite sanitary product of the present invention, a step of sandwiching the labia / pad body between the labia and a step of attaching the support sheet body to the underwear are required in the mounting procedure. If the latter process is performed first, the interlabial pad body and labia depend on the fastening position of the support sheet body to the underwear. Therefore, it is difficult to mount the interlabial pad body at an optimal position in the labia. On the other hand, if the former step is performed first, the interlabial pad body can be positioned within the labia first, so that the suitable attachment of the interlabial pad body can be easily performed.

For this reason, in mounting the composite sanitary product according to the present invention, it is preferable to first mount the interlabial pad body in the labia, and then fix the support sheet body to underwear. Specifically, the wearer's thumb and forefinger are inserted through the two finger insertion openings between both sides of the connection sheet and both sides of the interlabial pad body, and the interlabial pad body is pinched. While sensing the unevenness of the labia using the feeling of each fingertip, the interlabial pad body is guided and fitted to the optimal position within the labia, and then the support sheet body is attached to the underwear.

(14) The composite according to any one of (6) to (13), wherein a finger holding portion projecting in a direction opposite to the body is formed on a side opposite to the body of the interlabial pad body. Sanitary items.

According to the invention of (14), the finger holding portion is formed on the side opposite to the body of the interlabial pad body. For this reason, the wearer can easily pinch the interlabial pad body by pinching the finger-holding portion, whereby the wearer picks any part of the interlabial pad body in the longitudinal direction. It is possible to grasp the skin with the feeling of the wearer's own finger, and furthermore, it is possible to wear while pushing the labia through the interlabial pad body with the finger pinching the finger holding part, This interlabial pad body can be relatively easily fitted to the vestibular floor, which is the innermost part of the interlabial space.

In addition, the finger holding portion in the present invention can be formed in a finger insertion space following the finger insertion port in the composite sanitary product of (13). In this case, the finger holding portion can be held by the finger inserted from the finger insertion opening.

(15) The interlabial pad body has both sides in the short direction joined to the connection sheet, and at least one end in the longitudinal direction is not joined to the connection sheet. The composite sanitary article according to any one of (10) to (12), wherein the composite sanitary article is a finger insertion port through which a wearer's finger can be inserted.

According to the invention of (15), a finger insertion port is formed at an end in the longitudinal direction of the interlabial pad body. For this reason, the finger can be inserted while the fingernail side of the finger is covered with the connecting sheet and the fingerprint surface of the finger is almost in contact with the fingerprint surface along the longitudinal center line on the opposite side of the interlabial pad body. . Thus, while the interlabial pad body is fixed to the fingertip, the position of the vaginal opening is sensed by the fingerprint surface of the highly sensitive finger through the interlabial pad body, and the finger is moved along the longitudinally extending cleft. Can be along. As a result, it becomes possible to attach the interlabial pad body to the vestibular floor in close contact with almost the entire area in the longitudinal direction of the pad body.

(16) The composite sanitary product according to any one of (10) to (12), wherein a finger insertion port is formed on a side opposite to the body of the interlabial pad body or the connection sheet. .

According to the invention of (16), on the opposite side of the interlabial pad body, or on the opposite side of the connecting sheet when the interlabial pad body is attached to the side surface of the connecting sheet, A finger entry hole is provided to allow finger insertion. For example, the finger inlet is attached to the interlabial pad body on the side opposite to the body or the side opposite to the body of the connecting sheet so that the mie sheet piece has at least one non-joined portion. Thereby, a finger insertion port can be formed at the non-joined portion. This finger insertion By inserting a finger through the mouth, the fingernail side is brought into contact with the mini-sheet piece, and the fingerprint surface of the finger is brought into contact with the connection sheet along the longitudinal center line of the opposite side of the body, The interlabial pad body is fixed to the fingertip, so that it is possible to wear the interlabial pad body between the labia while sensing the position of the vaginal opening with the fingerprint surface of the highly sensitive finger through the interlabial pad body. It becomes possible. Furthermore, since it is possible to follow the finger along the cleft extending in the longitudinal direction, it is necessary to closely fit the entire area of the interlabial pad body in the longitudinal direction to the vestibular floor in a more optimal position. Becomes possible.

Moreover, even when a finger is inserted into the finger insertion port as in the composite sanitary products described in (13) and (15) above, the back side of the inserted finger and the connection sheet are Since there is no contact, the situation in which the connecting sheet hinders the attachment of the interlabial pad body to the labia can be avoided, and the complexity of the attachment can be reduced.

The hand from one of the spaces on both sides where the connecting sheet and the support sheet are separated. Then, the finger enters the finger insertion opening. In such a case, the finger is inserted into the finger insertion opening at an angle (oblique state) with respect to the longitudinal center line of the interlabial pad body, and the shadow extending in the longitudinal direction is formed. It is difficult to align the longitudinal centerline of the interlabial pad body with the fissure.

In this regard, according to the present invention, the end of the connection sheet having the finger insertion port is detachable from the sabot body, so that when the wearer inserts a finger into the finger insertion port, The end can be temporarily separated from the support sheet body. As a result, the finger can be inserted along the center line in the longitudinal direction of the interlabial pad body into the finger insertion slot and into the space following it without an angle (a straightforward state).

Moreover, since the finger can be relatively freely moved while the finger is inserted from the finger insertion opening into the finger insertion space, the interlabial pad body is fitted to a suitable place between the labia. It becomes easier.

After performing such an operation, the peeled end of the connection sheet is to be attached to the support sheet again.

In the present invention, the joining for making the connecting sheet detachable from the support sheet body is performed by using, for example, a fastener tape, a heat-sensitive adhesive, a pressure-sensitive tape, a pressure-sensitive adhesive alone or in combination. Can be.

Next, an embodiment of the sanitary product according to the present invention will be described with reference to the drawings. .

[Composite sanitary product of the first embodiment]

First, the basic configuration of the composite sanitary product of the first embodiment will be described. FIG. 1 is a schematic perspective view showing the composite sanitary product of the present embodiment, and FIG. 2 is a sectional view taken along line XX of FIG.

As shown in FIG. 1, the composite sanitary product of the present embodiment is The interlabial pad body 1 in the form of a long and thin piece having a longitudinal direction and a transverse direction large enough to be sandwiched, and the interlabial pad body 1 is arranged so as to overlap with the interlabial pad body 1, and the long side along the longitudinal direction is And a support sheet 2 having a dimension longer than at least the interlabial pad 1. The connecting sheet 3 made of an elastic elastic material capable of expanding and contracting in the longitudinal direction is joined to the sabot sheet body 2 at both ends in the longitudinal direction in an extended state. The support sheet 2 is in a state of being bowed by the elastic force. The interlabial pad body 1 is attached to the extended connection sheet 3 at a substantially central portion in the longitudinal direction.

The interlabial pad body 1 is joined to the connection sheet 3 at both ends in the longitudinal direction, and is not joined to the connection sheet 3 on both sides in the short direction. In this non-joined part, a finger insertion opening 10 is formed between the connection sheet 3 and the interlabial pad body 1 so that a wearer can insert a finger.

As shown in FIG. 2, the interlabial pad body 1 has a water-permeable front sheet 4 facing the body side and a water-permeable or water-impermeable back sheet 5 facing the opposite body side from inside the labia. It has a structure that contains an absorber 6 that absorbs outflowing menstrual blood.

The support sheet body 2 also has substantially the same structure as the interlabial pad body 1, and has a water-permeable front sheet 7 facing the body side and a water-impermeable back sheet 8 facing the opposite body side. Has a structure in which the absorber 9 is included. The support sheet body 2 absorbs menstrual blood leaked from the inner surface of the labia to the outside without being absorbed by the interlabial pad body 1 with the absorbent body 9 through the front side sheet 7, and the water-impermeable back surface. The side sheet 8 prevents the wearer's underwear from becoming dirty. · <Attached state>

FIG. 3 is a schematic cross-sectional view showing a state in which a finger is inserted into the finger insertion port 10, and FIG. 4 is a longitudinal longitudinal section showing a state in which the composite sanitary product of the first embodiment is attached to underwear 13. FIG. 5 is a short-side longitudinal sectional view showing a state in which the composite sanitary product of the first embodiment is attached to underwear 13.

In the case of wearing the composite sanitary product having the above-described configuration, as shown in FIG. 3, first, the wearer inserts a finger pad formed between the connecting sheet 3 on both sides of the interlabial pad body 1. Insert the finger from the mouth 10 (thumb and index) and hold the interlabial pad body 1 at the fingertip. Then, in this state, the interlabial pad body 1 is worn between the labia.

Subsequently, as shown in FIG. 4 (A), the adhesive 12 is applied on the opposite body side of the support sheet body 2 (both ends on the opposite body side of the back sheet 8). Then, the support sheet body 2 is fixed to the underwear 13 via the adhesive 12. By fixing the support sheet body 2 to the underwear 13, the displacement of the mounting position of the support sheet body 2 can be reduced, and the interlabial pad body 1 can be prevented from dropping out of the labia. When the support sheet 2 is attached to the underwear 13, the support sheet 2 follows the surface shape of the underwear 13, as shown in FIG. Deform to. The connecting sheet 3 connected to the front and rear ends of the support sheet body 2 is pulled forward and rearward with the deformation of the support sheet body 2, and is moved forward and backward by the elastic elasticity of the connecting sheet 3. Will be extended.

After attaching the support sheet body 2 to the underwear 13, the connecting sheet 3 stretched in this way has a resilience to return to the original state before the attachment due to elasticity and elasticity, contrary to the case of attaching the support sheet body 2 to the underwear 13. work. For this reason, it is supported in a hollow state in the natural state before mounting, as shown in Fig. 5 (A). The interlabial pad body 1 is pushed up toward the body by the restoring force of the connecting sheet as shown in FIG.

Then, when the wearer wears the underwear 13 to which the support sheet body 2 is fixed, the interlabial pad body 1 is moved by the wearer's underwear lifting operation as shown in FIG. The pressing force applied to 1 and the stress from labia 11 are generated against this pressing force. With respect to this stress, a repulsive force is generated due to the elasticity of the connecting sheet 3 to which the interlabial pad body 1 is attached. This repulsive force is a force that pushes up the interlabial pad body 1 in the direction of the labia.The pushing force pushes the interlabial pad body 1 toward the body, and the interlabial pad body 1 is stabilized between the labia 1 and 1. Will be fixed.

In order to explain in more detail the mounting state of the composite sanitary device of the present embodiment, the mounting operation will be described in order. Fig. 6 (A) is a diagram in which an interlabial pad body is attached between labia, Fig. 6 (B) is a diagram showing a state in which a support sheet body is attached to underwear, and Fig. 6 (C) is FIG. 6D is a diagram showing a state in which the undergarment is pulled up, and FIG. 6D is a partial cross-sectional view in which an unnecessary portion is cut away in order to specifically explain the lifting force.

First, as shown in FIG. 6 (A), the interlabial pad 1 is inserted between the labia 11. Subsequently, as shown in FIG. 6 (B), the support sheet 2 is fixed to the underwear 13. As a result, the support sheet body 2 is slightly deformed into a flat shape, and the connecting sheet 3 in the extended state is further extended and becomes taut. Then, the underwear 13 is pulled up, and the wearer wears it properly, so that the interlabial pad body 1 attached to the connection sheet 3 is pushed up by the connection sheet 3 having elasticity and elasticity. And the fitting state between the labia 11 is fixed. That is, as shown in FIG. 6 (C), the composite sanitary product of the present embodiment is: Since the base point 3 A of the front end of the connection sheet 3 is located ahead of the wearer's front labia commiscia and the rear end base point 3 B is located behind the rear labia commiscia, the wearer's underwear 1 When the user pulls up 3 and wears it, the connection sheet 3 curves between the front end base point 3A and the rear end base point 3B. In this case, the connecting sheet 3 has a restoring force, which tends to return to the original linear shape, due to its elastic expansion and contraction force, between the front end base point 3A and the rear end base point 3B. Occurs. When the underwear 13 is worn, the interlabial pad body 1 mounted on the connecting sheet 3 is pushed up into the labia 1 1 so as to be lifted toward the body side, and the interlabial pad body 1 is lifted. It is possible to reduce the situation of falling off from between the labia 1 and 11.

More specifically, the force by which the connecting sheet 3 pushes up the interlabial pad body 1 is as shown in FIG. 6 (D). On the other hand, the A vector solid, which is a composite vector of the shrinking force a 1 vector and a 2 vector, is generated. This A solid is the push-up force of the connecting sheet 3 to push up the interlabial pad body 1, and the force to maintain the interlabial pad body 1 between the labia 11 and 11.

When the underwear is lifted, the support sheet body 2 will bend from the flat shape shown in FIG. 6 (B) to the concave shape shown in FIG. 6 (C). Due to such deformation of the support sheet body 2, a force is applied to the connection sheet 3 from a direction other than the extension direction, but even if this force is applied, the connection sheet 3 returns to the original state. Due to the restoring force, the connecting sheet 3 can easily maintain a straight state.

Next, the dimensions of each component will be described. FIGS. 7 and 8 are illustrations for explaining an example of the length dimension of the connection sheet 3 and the support sheet body 2. FIG. 9 is a schematic perspective view showing the length dimension of the interlabial pad body 1.

In this specification, “apparent” means a distance between two points having the shortest length (corresponding to S2 in FIG. 8, L1 and L2 in FIG. 9). This is because, in relation to the manufacturing process, there is a case where the distance between two points in the uneven shape is treated as an actual length, that is, the distance between the two points in a flat state where the uneven shape is developed may be treated. It has been carefully defined.

The lengths of the support sheet body and the connection sheet in the present embodiment will be described by way of an example. For example, the length in the longitudinal direction of the connection sheet 3 before joining to the support sheet body 2 is 10 Omm, and is R1 shown in FIG. On the other hand, the length dimension of the support sheet body 2 in the longitudinal direction is set to 180 mm and is set to S1 shown in FIG. In such a case, when joining the connection sheet 3 to the support sheet body 2, the connection sheet 3 made of an elastic elastic material is used to make the support sheet body 2 and the connection sheet 3 the same size. It will extend in the longitudinal direction to a length of O mm.

When the above-described joining is performed, a contracting force acts on the connecting sheet 3 so as to return to the original length dimension R1. On the other hand, the support sheet 2 has a bending rigidity of 1.5 to 10 m NZ 25 lm in the present embodiment, so that the connection sheet 3 repels the flattening force against the reduction force. Trying to maintain a good state. When the contraction force of the connection sheet 3 and the bending rigidity of the support sheet body 2 are in a state of equilibrium, the connection sheet 3 has an apparent dimension of 14 Omm, which is the dimension of R3 shown in FIG. In addition, the support sheet body 2 is deformed in an arcuate shape with the reduction of the connecting sheet 3, and its apparent dimension becomes the dimension of S2 shown in FIG. As is clear from the above example, the elastic force of the connection sheet 3 and the rigidity of the support sheet body 2 are in a state of equilibrium. In a natural state, a composite sanitary product as shown in FIG. 1 in a state where the interlabial pad body 1 is floated in the air is obtained.

In the above example, the elongation ratio of the connecting sheet is as follows: when R1 is 100%, R2 is 180% and R3 is 140%. In the case of the composite sanitary product, the elongation ratio is 40% as compared with the non-elongated state.

[Connecting sheet]

The apparent length dimension (R 3 shown in FIG. 8) along the longitudinal direction of the connection sheet 3 is 18 O mm in the present embodiment, but is within a range of 80 to 300 mm. It is sufficient if it is configured, and it is more preferable that the thickness be in the range of 150 to 250 mm.

At this point, if the dimension of R3 is larger than 30 Omm, a push-up force to the body may be generated to an unnecessarily large area, which may cause discomfort to the wearer. On the other hand, if the apparent length is smaller than 8 Om m, the connecting sheet 3 is worn without being located forward and backward from the front and back labia commiscia at the time of wearing. For this reason, the connecting sheet between the front and rear starting points is less likely to bend in the body side direction, and the pushing force toward the body side is weakened. As a result, the interlabial pad body may fall off from between the labia.

In contrast, by setting the length of the connection sheet 3 to the above-described length, the risk of the interlabial pad body 1 falling off from between the labia can be prevented without causing discomfort to the wearer.

(Interlabial pad body)

The apparent length dimension along the longitudinal direction of the interlabial pad body 1 is L 1 shown in FIG. 9, and the dimension of L 1 is in the range of 50 to 16 O mm, and further, in the range of 80 to Preferably, it is in the range of 130 mm.

If the length dimension of L 1 is greater than 16 O mm, it is interposed between the labia Unnecessary rubbing of the wearer's vulva, napkin, shorts, etc. causes unnecessary friction, and the impact is transmitted to the area interposed between the labia, causing the interlabial pad body 1 and the inner surface of the labia There is a danger that gaps will occur between them. On the other hand, if the length dimension is smaller than 5 O mm, it is difficult to make contact with the entire longitudinal region of the labia, and menstrual blood may flow out from the inaccessible region.

In this regard, by setting the length dimension of L1, which is the apparent length dimension along the longitudinal direction of the interlabial pad body 1, to the above-mentioned dimension, it is possible to effectively prevent menstrual leakage. Can be.

The apparent width dimension of the interlabial pad body 1 along the lateral direction is L2 shown in FIG. 9, and the dimension of L2 is 10 to 6 O mm, and furthermore, 20 to 4 O, preferably in the range of O mm.

If the dimension of L2 is larger than 6 O mm, the area that is not interposed between the labia rubs on the wearer's vulva, napkin, shorts, etc. more than necessary, causing friction. The impact is transmitted to the region interposed between the labia, and there is a risk that a gap may be generated between the inner surface of the labia and the interlabial pad body 1. On the other hand, if the width dimension is smaller than 1 O mm, it becomes difficult for the interlabial pad body 1 to come into contact with the entire region of the inner surface of the labia in the transverse direction, and there is a risk that menstrual blood may flow out of the region where the contact cannot be made. Will be.

In this regard, by setting the dimension of L2, which is the apparent width dimension along the lateral direction, to the above-described dimension, leakage of menstrual blood can be effectively prevented. The dimensions of the components described above are not particularly suitable for this embodiment, but are also suitable for other embodiments of the composite sanitary product according to the present invention.

[Composite sanitary product of the second embodiment] Next, another embodiment of the composite sanitary product of the present invention will be described. FIG. 10 is an explanatory diagram illustrating a state in which the finger holding portion 26 formed on the opposite body side of the interlabial pad body 20 is pinched with the finger 22 in the composite sanitary product of the second embodiment. .

As shown in the first 0 Figure, the compound sanitary articles of the second embodiment, on purpose as in the first embodiment form a interlabial pad body 2 0 and support sheet ^{2 4,} both sheets. One DOO body The connection sheet 21 is connected. In addition, finger insertion openings 23 are formed between both sides of the interlabial pad body 20 and the connecting sheet body.

And, unlike the composite sanitary product of the first embodiment, in the finger insertion space following the finger insertion port 23, a finger protruding downward on the opposite body side of the interlabial pad body 20. 26 are formed. For this reason, when the wearer inserts the finger 22 from the finger insertion port 23, the interlabial pad body 20 can be easily pinched by pinching the finger pinching portion 26 located behind the finger 22. The positional relationship in the longitudinal direction of the interlabial pad body 20 can be grasped. Further, since the labia can be expanded by the rigidity of the fingers 22, the interlabial pad body 20 can be relatively easily fitted to the vestibular floor, which is the innermost part of the interlabial space. Becomes possible. .

As shown in FIG. 10, the interlabial pad body 20 in this embodiment has a water-permeable front sheet 27 on the body side and a water-impermeable back sheet 25 on the non-body side. And an absorber 28 for absorbing menstrual blood contained between the two sheets 27 and 25.

[Composite sanitary product of the third embodiment]

Further, a composite sanitary product according to another embodiment of the present invention will be described. FIG. 11 shows a composite sanitary product according to the third embodiment, in which a finger input port 33 is formed at one end 3OC in the longitudinal direction of the interlabial pad body 30. FIG. 12 is a perspective view showing a sanitary product, and FIG. 12 is a cross-sectional view for explaining a state where a finger is inserted into a finger insertion port 33.

As shown in FIG. 11, the interlabial pad body 30 is formed by joining both sides 30 A and 30 B of the interlabial pad 30 to the connecting sheet 31 in the short direction, and forming one of the two pieces in the longitudinal direction. The end portion 30C is not joined, and a finger entry hole 33 for inserting a wearer's finger into the connection sheet 31 is provided.

Further, in this embodiment, the connection sheet 31 itself is made of an inelastic material, but the elastic sheet 3 2 is attached along the longitudinal direction of both side edges of the connection sheet 31, so that the connection sheet 3 1 Has elasticity. In the composite sanitary product of the present embodiment, since the finger insertion space following the finger insertion port 33 is formed along the longitudinal direction of the interlabial pad body 30, as shown in FIG. The finger can be inserted almost along the center line in the longitudinal direction of the back side sheet 34 arranged on the opposite side of the interlabial pad body 30, and the fingerprint surface 38 of the finger can be Can be contacted. For this reason, it is possible to sense the position of the vaginal orifice with the fingerprint surface 38 of the highly sensitive finger through the interlabial pad body 30 and to follow the finger along the cleft extending in the longitudinal direction. . As a result, it is possible to attach the interlabial pad body 30 to the vestibular floor in close contact with almost the entire area in the longitudinal direction of the interlabial pad body 30. In the composite sanitary product according to this embodiment, the connecting sheet 31 is joined at both ends in the longitudinal direction at both ends of the support sheet body 34, and the interlabial pad body 30 is connected to the body. A water-permeable front-side sheet 35 on the side and a water-permeable or non-reachable back-side sheet 36 on the opposite side of the body, and an absorbent body 3 7 that absorbs menstrual blood with both sheets 35, 36 It has a configuration in which is included.

[Composite sanitary product of fourth embodiment] Next, a composite sanitary product according to a fourth embodiment will be described. FIG. 13 shows a composite sanitary product according to the fourth embodiment, which is formed by attaching a mini-sheet piece 42 to a portion corresponding to the interlabial pad body 40 on the side opposite to the body of the connecting sheet 41. FIG. 14 is a schematic cross-sectional view showing a state where a finger is inserted into the inserted finger insertion port 43. FIG. 14 is an end 4 of the link sheet 41 on the side where the finger insertion hole 43 is formed. Fig. 15 is an explanatory view for explaining a state in which 1A is removed from the support sheet body 44 and the interlabial pad body 40 is sandwiched between the labia. FIG. 9 is an explanatory diagram for explaining a state in which the end of the interlabial pad body 40 is attached to the support sheet body 44 after the work of sandwiching the underwear, and then the underwear 45 is worn.

As shown in FIG. 13, in the composite sanitary product of the present embodiment, an interlabial pad body 40 is physically attached to an upper surface of a connection sheet 41, and is attached to a lower surface of the connection sheet 41. The mini-sheet piece 42 is attached at a position corresponding to the interlabial pad body 40. A finger insertion opening 43 through which a wearer's finger can be inserted is formed between the connection sheet 41 and the mini sheet piece 42.

Since the finger input port 43 is formed below the connection sheet 41, when the wearer inserts a finger, the back side of the wearer's hand does not come into contact with the connection sheet 41, The situation where the connecting sheet 41 obstructs the insertion is avoided.

Further, as shown in FIG. 14, the connection sheet 41 is detachably attached to the support sheet body 44 at the end 41 A on the side where the finger entry port 43 is formed. It has a possible mounting part 49.

For this reason, when attaching the composite sanitary product of the present embodiment, when the end 41 A of the connection sheet 41 is peeled off from the support sheet body 44, a finger is inserted substantially along the center line in the longitudinal direction. A finger can be inserted into the mouth 43. this Not only facilitates the insertion of the finger, but also increases the degree of freedom of movement of the finger in the state of being inserted into the finger insertion opening 43, so that the interlabial pad body 40 can be easily fitted between the labia. Becomes possible.

Then, after the interlabial pad body 40 is fitted between the labia, the peeled end 41A of the connection sheet 41 is again attached to the support sheet body 44, and then the support sheet body 44 is attached. It can be attached to the underwear 45, and the underwear 45 can be worn as shown in FIG.

[Other configurations of composite sanitary products]

Next, other configurations that can be employed in the composite sanitary products having various configurations as described above will be described.

Fig. 19 shows a composite sanitary product in which a connecting sheet and a support sheet are constituted by two bands. FIG. 20 is a perspective view for explaining the support sheet body 94 composed of only one edge and a connecting sheet composed of one band 91 or a support sheet composed of two bands 94A and 94B. It is a perspective view for explaining the composite sanitary product constituted by the sheet body.

As shown in FIG. 16, the interlabial pad body 50 mounted on the connection sheet 51 can be fitted with an elastic elastic member 52 along the longitudinal center line. It is. With such a configuration, it is possible to cause the interlabial pad body 50 itself to push up to the body side by the elastic stretching material 52, and to add the pushing force of the connection sheet 51 to the body side. Push-up force can be increased. With this, between the labia 'The adhesion between the pad body 50 and the vestibular floor in the labia that contacts along the longitudinal center line of the pad body 50 is further improved, and the dropout from between the labia is reduced. Further, in the composite sanitary product of the present invention, as shown in FIG. 17, the connecting sheet 61 is made permeable, and the absorbent 62 that absorbs menstrual blood is enclosed by a permeable force sheet 63. It is also possible to attach the interlabial pad body 60 having the above configuration to the opposite body side of the connection sheet 61 and to interpose between the connection sheet 61 and the support sheet body 64.

According to the composite sanitary product having such a configuration, since the connecting sheet 61 is located on the body side of the interlabial pad body 60, the thickness and density of the absorber 62 in the interlabial pad body 60 are provided. Thus, the buffering of the pushing force of the connection sheet 61 against the interlabial pad 60 is reduced. Therefore, it is possible to enhance the adhesion between the interlabial pad body 60 and the inner surface of the labia 68 through the connecting sheet 61, and furthermore, to maintain the underwear 6 9 while maintaining this state. It becomes possible to put on.

The support sheet body 64 has substantially the same configuration as that used in the above-described embodiment. The support sheet body 64 has a water-permeable front side sheet 65 disposed on the body side and a water-impermeable back side disposed on the opposite body side. It has a configuration in which an absorber 67 for absorbing body fluid is included in the side sheet 66.

In the composite sanitary product of the present invention, the connecting sheets need not be a series, but may be composed of two connecting sheets 71A and 71B as shown in FIG. Specifically, the connecting sheet 71A is joined to the front end of the interlabial pad body 70 and the front end of the support sheet body 74, and the connecting sheet 71B is placed behind the interlabial pad body 70. It is joined to the end and the rear end of the support sheet 74.

As shown in FIG. 19 (A), the connecting sheet is made up of two bands 81A and 81B, on which the interlabial pad body 80 is attached. As shown in FIG. 9 (B), not only the connection sheet but also the support sheet body can be composed of two bands 84A and 84B. By doing so, the interlabial pad body 80 is pushed up from both sides, and in particular, both sides come into close contact with the body, so that menstrual leakage from both sides of the interlabial pad body 80 is prevented. can do.

Further, as shown in FIG. 20 (A), the support sheet body 94 is composed of only a substantially rectangular edge, and the connecting sheet composed of one band 91 is connected to the center part 94 A of the front edge. It can also be attached so as to bridge to the central portion 94 B of the trailing edge, and an interlabial pad body 90 can be attached on this band 91.

Furthermore, as shown in Fig. 20 (B), the support sheet body is composed of only two bands 94A and 94B, and is attached to the front and rear ends of the band 91, which is a connecting sheet. It is also possible to

As shown in FIGS. 20 (A) and 20 (B), when a band-like connecting sheet is attached to the central part of the interlabial pad body 90, a series of sheets are also formed. Since the area of contact with the skin can be reduced as compared with the case of the above configuration, it is possible to reduce the occurrence of discomfort and stuffiness when worn. In addition, since the interlabial pad body 90 is pushed up at the center, it easily becomes convex and is easily sandwiched in the back between the labia.

[Composition materials for composite sanitary products]

<Water-permeable sheet>

For the water-permeable sheet placed on the body side of the composite sanitary product, a material that is liquid-hydrophilic and does not irritate the skin is used. Examples of such materials include nonwoven fabrics obtained from manufacturing methods such as mesolet blown, sham bond, point pond, sleigh air, point pond, udle punch, wet type, wet spunlace, and foam film, alone or in combination. Lumber Fees.

Examples of the fibrous sheet include sheets made of a single or mixed fiber containing rayon, acetate, cotton, pulp, or a synthetic resin as a component, or a composite formed into a core-sheath structure.

Among these materials, considering the liquid mobility from the inner surface of the labia and the chemical irritation caused by the active agent, fibers containing 5 to 30% of natural cotton and 70 to 95% of rayon or acetate are used. After adjusting to a range of 20 to 50 g / m ² , fibers are entangled by hydroentanglement and dried, and a spunlace nonwoven fabric having a thickness adjusted to a range of 0.3 to 1.0 mm is preferable. The yarn quality used in this case is selected from the range of 15 to 6 Omm for natural cotton, 25 to 51 mm for rayon or acetate, and 2.2 to 6.6 dte X. It is.

Sorbents>

The materials used for the absorbent included in the composite sanitary product include pulp, chemical pulp, rayon, acetate, natural cotton, polymer absorbent, fibrous polymeric absorbent, and synthetic fiber alone or in combination. Things can be used.

As the sheet-like material, these may be processed into a sheet-like or powdery form and used, and are not limited to the method of use.

The absorber should be capable of absorbing and retaining a liquid (body fluid), but is preferably bulky, hard to lose its shape, and has little chemical irritation. More specifically, fibers obtained by laminating rayon or acetate selected from the range of 1.1 to 4.4 dte X at a mixing ratio of 60 to 90% and a fibrous polymer absorber at a mixing ratio of 10 to 40%, Nonwoven sheet with bulk of 150 SOO gZm ² 2 to 5 mm When the absorbent as described above is incorporated in a composite sanitary product, the volume can be adjusted as appropriate by adjusting the bulk, overlapping, or folding as necessary.

As a material of the impermeable sheet used in the composite sanitary product, a material that can prevent menstrual blood held in the absorbent from leaking out of the composite sanitary product can be used. Further, by using a moisture-permeable material, it is possible to reduce stuffiness at the time of wearing, and it is possible to reduce discomfort at the time of wearing.

Examples of such a material include a sheet-like film in which a synthetic resin is formed into a film, a breathable film obtained by filling an inorganic filler and performing a stretching treatment, a paper, a laminate obtained by combining a nonwoven fabric and a film, 1 Use a gas-permeable liquid blocking sheet obtained by arranging a capillary in the range of 0.1 to 0.6 mm and having a pore diameter of 0.1 to 0.6 mm toward the absorbent body. be able to.

Furthermore, in consideration of the flexibility that does not impair the feeling of wearing, for example, the basis weight is mainly low density polyethylene (LDPE) resin having a density of 0.90 to 0.925 g Z cm ³ . It is preferred to use a film obtained from a range of 15 to 30 g / m ² .

The connection sheet is not limited to a water-permeable material or a water-impermeable material. Rather than having elastic elasticity, the elastic elastic material and the elastic elastic material are joined to the non-elastic elastic material in a stretched state. It can be composed of a fibrous sheet / film sheet using a combination with a material or using an elastomer resin.

About bonding between each sheet> Heat embossing is used to join both ends in the longitudinal direction of the connecting sheet and both ends in the longitudinal direction of the support sheet body, to join the interlabial pad body to the connecting sheet, and to join the peripheral sheet between the front side sheet and the back side sheet. In addition, hot-melt adhesives can be used alone or in combination.

Further, the absorber is stuck to each sheet in order to prevent separation between layers of the front side sheet and the back side sheet from the absorber. In this case, it is possible to prevent the above-described layer separation by setting the front side sheet and the back side sheet together with the peripheral edge and the inner edge excluding the peripheral edge from the inner edge.

When the composite sanitary product is used (when wet with menstrual blood), interlayer separation is likely to occur in each part, but in order to prevent this, it is more preferable to bond each part by heat embossing. The heat embossing process can be used without limitation in a dot-shaped or screen-patterned pattern. It is possible to maintain the wet strength without hindering the water permeability. In the composite sanitary product according to the present invention, the front-side sheet and the back-side sheet are integrally formed at the periphery so that the interlabial pad body and the support sheet body confine the absorbent body. In such a case, it is preferable that the absorber is not pinched at the peripheral edge of the joint. For example, by joining only the front-side sheet and the back-side sheet so that the absorber is confined in a bag-like area surrounded by the joint at the periphery, the absorber is sandwiched between the periphery and Hardening of the periphery is avoided, and the feeling of wearing is more suitable.

The size of the absorber may be approximately the same as the size of the interlabial pad body / support sheet body, so that the absorber is not sandwiched in the peripheral edge. For this purpose, the dimensions may be reduced in advance so that an interval in the range of 2 to 10 mm is provided from the outer contour of the interlabial pad body.

As the elastic elastic material provided in the interlabial pad body, for example, an elastomer component, a foamed material such as foamed polyethylene, or the like may be used alone or as required. Specific examples of elastic elastic materials include polyester-based, urethane-based, olefin-based, styrene-based, and polyamide-based thermoplastic elastomers as examples of elastomer components, LDPE resins using a meta-mouth catalyst, Ethylene mono-α-olefin copolymerization, etc., may be used singly or as necessary. '

As an example of a polyester-based elastomer, an aromatic polyester is used as a hard segment, and an amorphous polyether or an aliphatic polyester is used as a soft segment.

Thermoplastic urethane elastomers are polyurethanes made of polyester, low molecular weight glycol, methylenebisphenylisocyanate, etc., and are obtained by addition polymerization of polyisocyanate in the presence of a short-chain polyol to a polyratatone ester polyol. Things.

Examples of the olefinic elastomer include an ethylene-α-olefinic random copolymer and a copolymer obtained by copolymerizing gen as the third component.

Styrene-based elastomers include styrene-butadiene-styrene block copolymer (SBS), styrene-isoprene-styrene block copolymer (SIS), styrene-ethylene-butadiene-styrene block copolymer (SEBS) And block copolymers such as styrene-ethylene-propylene-styrene block copolymer (SEPS). Examples of the polyamide-based elastomer include a polyamide-based synthetic fiber as a hard segment and a polyester or polyol as a soft segment.

Further, in order to stabilize the molding of the elastic elastic material, for example, a high-density polyethylene, a LDPE resin, a linear low-density polyethylene or the like may be blended in the constituent polymer of the elastomer. Furthermore, it is also possible to add a blocking agent, an inhibitor, an ultraviolet ray absorbent, a thickener branching agent, an anti-glare agent, a coloring agent and other various improving agents.

The elastic elastic material may be made of a fiber aggregate, and the fiber aggregate is composed of an elastomer component and a non-elastomer component, so that the elastic elastic material obtained has the elasticity maintaining property and the fibers at the time of molding. Are preferably fused by heat.

Examples of the non-elastomer component in the composite fiber aggregate include a polyester component such as polyethylene terephthalate and polybutylene terephthalate, an olefin component such as polyethylene and polypropylene, and a polyamide synthetic fiber and acrylic. No. Further, the constituent polymer of the non-elastomer component may contain an ultraviolet absorber, a viscous branching agent, an anti-glare agent, a coloring agent, and other various improving agents. Examples of the conjugate fiber include a side-by-side type, a core-sheath type, an eccentric core-sheath type, and a sea-island type.

The support sheet body can be used by using an elastic elastic material alone or in combination with an absorber or the like.

When the support sheet body is formed by using the elastic elastic material alone, when the amount of excretion is large, it is the lower surface direction of the absorber and the position where the interlabial pad body and the support sheet body are separated. A sanitary napkin This makes it possible to absorb menstrual blood that could not be absorbed by the absorber and prevent it from flowing out.

In the case where the support sheet is formed of a combination of an elastic stretchable material and an absorber, for example, a water-permeable front side sheet covering the body side and a water-impermeable back side sheet covering the opposite body side are provided, for example. There is a configuration in which an elastic elastic material that is continuous in the longitudinal direction is arranged on the side opposite to the body surface of the absorber to be coated. With such a configuration, it is possible to maintain a structure in which the interlabial pad body is continuously and elastically lifted by the elastic expansion and contraction of the support sheet body, thereby preventing the interlabial pad from falling off between the labia, and Menstrual blood that could not be absorbed by the interlabial pad body can be absorbed by the absorber of the support sheet body, preventing menstrual blood from leaking outside.

It is preferable to use a mini-sheet piece that has a strength that does not break when a finger is inserted.Non-woven fabric sheet, elastic stretch non-woven fabric, film, foam film, elastic stretch film, foam sheet, tissue paper And the like, or can be adopted without limitation from a laminate material. Specifically, a film mainly composed of LDPE resin and having a thickness of 15 to 30 μm is exemplified. Also, for the mini-sheet pieces, in order to make it easier for the wearer to identify the mini-sheet pieces, a method such as printing of a color pattern or the like is used to obtain a different color tone or color from the connection sheet. It can also be adjusted to have a pattern and chromaticity.

The mini-sheet piece is extensible or elastic in the short direction of the connection sheet so that the composite sanitary product according to the present invention can be used effectively regardless of the size of the wearer's fingertip. It is also effective to have the property.

In order to make the mini-sheet piece extensible, a gripping feeling of 1 OO mm, An extensible spunbond nonwoven fabric or the like having a stress of 0.1 to 0.5 NZ25 mm at 5% elongation when stretched at a constant speed of 10 Om mZm in can be used.

Also, in order to give the mini-sheet piece elastic elasticity, it is necessary to use elastic elastomeric resin such as fibrous sheet or film sheet using thermoplastic elastomer resin and those thermoplastic elastomer resin or natural rubber. The material may be used alone or in combination with an inelastic stretch material. Further, by providing a very small unevenness at a portion of the connection sheet where the finger pad touches, the contact area between the belly surface of the fingertip and the clothing side surface of the connection sheet is reduced, and the pad between the fingertip and the labia is provided. The phenomenon such as sticking between the human body and the body can be suppressed. In this case, it is possible to prevent the condition of the fingertip of the wearer, for example, a situation in which the interlabial pad body is attached to a place not intended by the wearer due to the wet environment, and Since the finger can be smoothly pulled out after the wearing, the displacement after the wearing can be prevented.
