Sept. 19, 1961 w. G. MULHOLE ETAL DIAPER HOLDER Filed Nov. 7, 1956 @N N www N ULV United States Patent O 3,000,381 DIAPER HOLDER William G. Mulhole, Elizabeth, NJ., and John J. Osmar,
North. Little Rock, Ark., assignors to Chicopee Manufacturing Corporation, a corporation of Massachusetts Filed Nov. 7, 1956, Ser. No. 620,824 Claims. (Cl. 12S-284) This invention relates to diapering devices and holders for diaper pads, more particularly to a holder which is especially adapted to hold inexpensive diaper pads which are disposed of after one use.
The present invention contemplates a diaper pad holder which is adapted to hold a somewhat imsy, but highly absorbent disposable pad snugly in position on a baby without stretching the pad unduly, tearing it, or othervsu'se destroying its effectiveness as a diaper; and the diapering device which comprises a disposable pad of this type in such a holder.
The rear half of the diaper pad holder of this invention is extensible and elastic so that the holder may be tted tightly around the baby. r[he front end of the holder is relatively inextensible and adapted to hold the front end of the pad securely in position without slippage during use. Since the rear half of the holder is extended during use, the rear end of the pad is positioned in the holder in such a way that it may slip in the direction of its length to avoid stretching or tearing the pad, itself.
Other features and advantages of the invention will be apparent from the following description and claims taken together with the drawings wherein:
FIGURE l is a plan view of a diaper pad holder according to one embodiment of the invention with the extensible rear half of the holder in relaxed condition.
FIGURE 2 is a similar plan view of the holder of FIGURE 1 with the rear half of the holder extended to its full dimension.
FIGURE 3 is an enlarged broken sectional view along the line 3-3 of FIGURE 2.
Referring to the drawings, there is shown a waterproof diaper pad holder which is roughly T-shaped in its full dimension, or when it is fully extended, as shown in FIGURE 2. The line A-A passing approximately through the mid-point of the crotch portion of the holder divides the holder into a front part 11 and a rear part 12 which will be referred to sometimes hereinafter in the specification and claims as a front half and a rear half; the front half 11 being that below the line A--A in the iigures, and the rear half 12 being that above the line. Thus, the front half of the holder at the base of the T is relatively elongated and narrow, while the rear half of the holder is much wider across the top of the T.
The rear half of the holder is gathered when the holder is relaxed, as shown in FIGURE 1, to provide the required extensibility. 'Ihe rear part .12 of the holder body is gathered adjacent its top edge 13 and secured to elastic means 14 such as an elastic tape by zig-zag stitching or an equivalent technique to provide an extensible and elastic rear waist embracing portion 15. Somewhat concave leg embracing portions 16 are provided along each edge of the holder about the line A-A in the area of the crotch portion of the holder. As shown in FIGURE 1, the holder body is gathered above the line A-A in the leg embracing portions 17 of the rear half of the holder and secured to'extensible elastic means 18 by stitching or the like. Thus, both the rear waist embracing portion and the rear leg embracing portions 17 of the holder of FIGURE 1 are extensible and elastic. Generally speaking, the elastic means 14 on the Waist embracing portion will be quite resilient to assure that the holder stays in position and does not slip down from the babys waist.
Patented Sept. 19, 1.961
In contrast, the waist embracing portion 21 of the front half of the holder is not gathered and therefore only as extensible as the material of the holder body. Preferably, the body of the holder is formed from a sheet of relatively inextensible waterproof material, such as vinyl sheeting, or the like, with the result that the front half 11 of the holder is relatively inextensible. Preferably, also, a relatively inextensible reinforcing band 22 is provided, for strength purposes, along the waist embracing edge of this half of the holder.
For convenience in manufacturing and to reinforce the leg embracing portions 23 of the front half of the holder, the elastic means 18 of the leg embracing portions 17 of the rear half of the holder may be extended over and secured to the leg embracing portions of the front half, as shown in the drawings. However, the body of the holder in these areas is gathered only slightly, if at all, so that the leg embracing portions of the front half of the holder are, at best, relatively inextensible. The elastic means 18 could be confined to the rear leg embracing portions, in which case it would be preferable to reinforce the leg embracing edges of the front half of the holder by some other means, such as reinforcing strips or the like.
Fastening devices are provided on each side of the front and rear halves of the holder beyond their respective leg embracing portions. A set of three spaced snap halves 25 is positioned adjacent the edge of the holder along each side, at the front and rear thereof. Reinforcing strips 26 are stitched to the body of the holder in v these areas to prevent the snap halves 25 from loosening or pulling out. Preferably, male halves on the outer side of the rear half 12 of the holder enter and cooperate with female snap halves on the inner side of the front half 11 of the holder. However, this arrangement may be varied with the male halves being on the front half 11 of the holder and the female halves being on the rear half 12, or with the snap halves facing opposite sides of the same half of the holder.
Pad securing means in the form of a front strap 27 is provided adjacent the waist embracing portion 21 of the front half of the diaper holder. This strap 27 extends across the holder and is secured at each of its ends by stitching, or the like, to the reinforcing strips 26 along the sides of the front half of the holder. A rear strap 28 is secured to the rear half of the holder through a heat sealing ring 28A which surrounds the strap. Ihe ends of the strap are integral with corresponding portions of the heat sealing ring and the ring is heat sealed to the holder adjacent these portions in such a way that the unattached length of the strap between its ends is approximately equal to that of the front strap 27. Preferably, the unattached length of the rear strap 28 is at least about as great as the width of diaper pads to be used therewith and the strap is located centrally of the rear half of the holder so that a pad threaded therethrough is supported slidably in the rear part of the holder.
In use, the front end 31 of an elongated yabsorbent pad 30 is inserted under the front strap 27, then the body of the pad is folded over the strap 27 and the rear end of the pad is threaded under the rearV strap 28, while the holder is relaxed, as shown in FIGURE 1.
The baby then is placed on the rear half of thefpad- 30 and the front half of the holder is folded over the babysV abdomen with the leg embracing portions of the holder between the babys legs. The rear half 12 of theholderfv half of the holder. This snug iit prevents the front end of the pad 31 from becoming dislodged from the front strap 27. The rear half of the pad 30 is held in position by the generally close t of the holder around the babys body.
Even though the front end 31 of the pad is positively secured to the front half 11 of the holder by folding the end of the pad around the front strap 27, the front half o r' the pad is not stretched appreciably as the holder is tted around the baby because the front half of the pad is vrelatively inextensible. Thus, the front half of the pad and the front half of the holder retain their relative positions. Since the rear half 12 of the holder is extended as it is stretched around the babys body, the rear strap 28 is vdesignedto allow the rear end of the pad 3G to slide therethrough to avoid placing undue tension on the pad as the rear half 12 of the holder is extended. The relative motion between the rear half of the holder and the rear Yhalf of the pad is illustrated in the comparison between FIGURES l and 2, before and after stretching of the holder, respectively. Thus, the absorbent pad Ymay be relatively imsy or at least of low tensile strength. This allows the use of cheaper yet highly absorbent materials, such `as'ilufled Woodpulp, other ocky absorbent materials, and the like.
lt is preferred that the elastic strips 14 and 18 at the waist and leg encircling portions of the holderY be sheathed with an open netting 32 of a durable, preferably hydrophobic material such as nylon, or the like. Since this sheathing is positioned about the elastic when it is fully extended, it will become shirred or pleated in the relaxed condition of the Vholder as shown in FIGURE 1. The sheathing 32 improves the appearance of the holder and provides a cushioning eifect between the elastic 'strips andthe babys body.
The reinforcing strips 26 in the front and rear of the holdermay be extended up beyond lthe Waist embracing edges thereof to provide tabs 33 which may be used for opening the top snaps'or pinning the holder to the babys undershirt.
The body of the holder may be formed from a single sheet of a vinyl polymer or'copolymer, either pigmented for opacity or relatively clear and transparent. It is preferred that the sheet be opaque and white and embossed with a fine pattern to provide a textile-like texture to the holder. In the above-described structure, vinyl sheeting approximately'4 mils thick has given good results. Of course, any one of various similar materials may be eniployed Afor this purpose.
The -front waist band 22, the reinforcing strips 26, and
\ thefront and rear straps 27 and 28 each may be formed from na single layer of 4 mil vinyl sheeting folded upon itself` twice to provide a 3-ply strip, 12 mils thick. A single layer 12 mils thick, or a like structure, may be employed with equal advantage. Similarly, although stitching has been mentioned for use to secure the various parts of the holder together, with the exception of the backV strap 28 which has been described as heat sealed, heat sealing may be employed throughout, or an adhesive, or the like, may be used.
Having now described the invention in speciiic detail and exemplified the manner in which it may be carried into practice, it will be readily apparent to those skilled in the lart that innumerable variations, applications, modications, and extensions of the basic principles involved may be made without departing from its spirit or scope.
