Definitions
- the present invention relates to a method of manufacturing a brush for applying cosmetic products, in particular, mascara, to eyelashes.
- Twisted wire brushes for application of liquid-type cosmetics, such as for application of mascara to the eyelashes are well known in the art.
- the brushes are designed to pick up and hold a supply of mascara from the cosmetic container, and then deliver the mascara to the eyelashes as the brush is combed through the lashes by the user.
- Twisted wire brushes conventionally are manufactured by disposing a plurality of individual lengths of bristles transverse to and between substantially parallel, slightly spaced-apart thin metal wire lengths, such that the wire lengths generally bisect the filament lengths at their midpoints.
- the parallel wire lengths comprise the two substantially equal leg lengths formed from bending a single length of wire into a U-shaped configuration. The wire lengths are then twisted together to form a helical core, causing the bristles disposed between the wires to be clamped therebetween at about their midpoints.
- the segments of the bristles on either side of the clamped midpoint are caused to flare radially outward from the core and so form an elongate bristle brush portion of generally circular cross-section.
- the brush is generally provided with a handle which can comprise, or be affixed to, a cap or other closure for the cosmetic container.
- the bristles are usually comprised of nylon filaments.
- the patent discloses a mascara brush having a reduced number of bristles, said to be 35% to 80% less than in conventional mascara brushes, ostensibly of larger diameter, than the bristles employed in conventional mascara brushes at the time. This was believed to provide a better application of mascara and separation of lashes.
- the patent specifies mascara brushes having a bristle diameter from about 0.10 to 0.25 mm (e.g. about 0.004 to 0.010 inch) (4 mil to 10 mil) and with from approximately 10 to 40 bristles per turn of the helix.
- the concept of a mascara brush having larger diameter fibers was further discussed in a recent PCT application no. PCT/US01/04555.
- This application is directed towards mascara brushes made from filaments that are relatively large but soft.
- the application describes mascara brushes having preferably having 7-14 bristles per turn.
- the bristle filaments are defined as preferably being from 0.010 inch to 0.013 inch (10 mil to 13 mil).
- the bristles are defined as being relatively soft being made of a thermoplastic elastomer having a durometer of between 62 Shore D and 82 Shore D, but most preferably about 72 Shore D.
- PCT application PCT/US01/04555 essentially defines a mascara brush made with a duPont Filaments filament sold under the trademark “Supersoft.”
- the “Supersoft” filaments have a durometer of 72 Shore D and are available as solid filaments or as triocular filaments having three hollow voids.
- Mascara which is typically highly viscous, tends to clump when applied to eyelashes.
- the clumps of mascara are typically combed out as a finishing step to the application process.
- Stiffer bristles are thought to be better suited for combing out clumps and properly separating lashes.
- the combing and separating functions are thought to be better accomplished with brushes a having relatively open bristle envelope or brush surface, i.e., an envelope or surface that has numerous or wide clearances or spaces between bristles to make the brushes more ‘comb-like’. This function is not well served by traditional mascara brush designs having smaller diameter bristles with higher bristle density.
- a mascara brush with softer, more numerous bristles has been generally thought to be well suited for applying mascara but less well suited for combing out clumps and separating lashes.
- a brush with stiffer, fewer bristles has been thought to be well suited for combing and separating lashes but less well suited for applying mascara to lashes.
- a separate brush can be used for each function, i.e., a soft brush for application and a stiff brush for combing
- a single brush that can both apply mascara and comb out clumps would be preferred for the convenience of the user.
- An example of a brush said to provide good application and combing characteristics is shown in U.S. Pat. No. 5,238,011 to Gueret.
- the Gueret patent discloses bristles made of a soft material having a shore hardness of 20A to 40D (as noted above, a conventional bristle typically has a durometer of over 85D), and a large diameter in a range of 0.004 inch to 0.014 inch (4 to 14 mil) (0.10 to 0.35 millimeter). As disclosed by Gueret, the diameter is said to be sufficiently large to prevent too high a degree of suppleness. The resulting brush is said to have the same degree of suppleness or softness as a conventional softer brush.
- a method of manufacturing a mascara brush provides a mascara brush with bristle fibers that are split into numerous fragments.
- the mascara brush is made with bristle fibers having longitudinal voids.
- the brush is then conditioned by passing a rotating splitting tool along the body of the mascara brush.
- the splitting tool splits the bristle fibers into numerous bristle fragments.
- the conditioned brush is softer to the touch than the original mascara brush.
- the conditioning can be applied to the entire brush or one or more zones of the brush.
- the conditioning can be shallow, so that only the bristle tips are conditioned, or deep, so that a substantial length of the bristle is conditioned.
- the conditioned bristles comprise about two to ten bristle fragments formed from each original bristle, more typically, about two to six bristle fragments formed from each original bristle.
- FIG. 1 is FIG. 1 is a side elevation view of a mascara brush in accordance with the invention.
- FIG. 2 is a cross-sectional view of a hollow bristle, made from a triocular filament having three longitudal hollow voids.
- FIG. 3 is a side elevation view of a bristle end which has been split by a wire wheel.

Abstract
Description
- This application is a divisional application of U.S. patent application Ser. No. 10/175,567, filed Jun. 18, 2002.
- The present invention relates to a method of manufacturing a brush for applying cosmetic products, in particular, mascara, to eyelashes.
- Twisted wire brushes for application of liquid-type cosmetics, such as for application of mascara to the eyelashes, are well known in the art. The brushes are designed to pick up and hold a supply of mascara from the cosmetic container, and then deliver the mascara to the eyelashes as the brush is combed through the lashes by the user.
- Twisted wire brushes conventionally are manufactured by disposing a plurality of individual lengths of bristles transverse to and between substantially parallel, slightly spaced-apart thin metal wire lengths, such that the wire lengths generally bisect the filament lengths at their midpoints. Most typically, the parallel wire lengths comprise the two substantially equal leg lengths formed from bending a single length of wire into a U-shaped configuration. The wire lengths are then twisted together to form a helical core, causing the bristles disposed between the wires to be clamped therebetween at about their midpoints. In the twisting and clamping, the segments of the bristles on either side of the clamped midpoint are caused to flare radially outward from the core and so form an elongate bristle brush portion of generally circular cross-section. The brush is generally provided with a handle which can comprise, or be affixed to, a cap or other closure for the cosmetic container. The bristles are usually comprised of nylon filaments.
- It is known in the art that this helical wire twisting method for forming cosmetic applicator brushes typically leads to a brush configuration in which the bristles tend generally to follow the helical pattern of the twisted wire core, i.e., whereby the tips of the bristles define a helix. Standard mascara brush designs of the 1960s and 1970s used smaller diameter bristles in fairly large numbers of bristles per turn. The state of the art then evolved to a somewhat larger diameter bristle, as defined in U.S. Pat. No. 4,887,622 entitled “Brush for the Application of Mascara to the Eyelashes.” The patent discloses a mascara brush having a reduced number of bristles, said to be 35% to 80% less than in conventional mascara brushes, ostensibly of larger diameter, than the bristles employed in conventional mascara brushes at the time. This was believed to provide a better application of mascara and separation of lashes. The patent specifies mascara brushes having a bristle diameter from about 0.10 to 0.25 mm (e.g. about 0.004 to 0.010 inch) (4 mil to 10 mil) and with from approximately 10 to 40 bristles per turn of the helix. The concept of a mascara brush having larger diameter fibers was further discussed in a recent PCT application no. PCT/US01/04555. This application is directed towards mascara brushes made from filaments that are relatively large but soft. Specifically, the application describes mascara brushes having preferably having 7-14 bristles per turn. The bristle filaments are defined as preferably being from 0.010 inch to 0.013 inch (10 mil to 13 mil). Most critically, the bristles are defined as being relatively soft being made of a thermoplastic elastomer having a durometer of between 62 Shore D and 82 Shore D, but most preferably about 72 Shore D. PCT application PCT/US01/04555 essentially defines a mascara brush made with a duPont Filaments filament sold under the trademark “Supersoft.” The “Supersoft” filaments have a durometer of 72 Shore D and are available as solid filaments or as triocular filaments having three hollow voids.
- Mascara, which is typically highly viscous, tends to clump when applied to eyelashes. The clumps of mascara are typically combed out as a finishing step to the application process. Stiffer bristles are thought to be better suited for combing out clumps and properly separating lashes. However, the combing and separating functions are thought to be better accomplished with brushes a having relatively open bristle envelope or brush surface, i.e., an envelope or surface that has numerous or wide clearances or spaces between bristles to make the brushes more ‘comb-like’. This function is not well served by traditional mascara brush designs having smaller diameter bristles with higher bristle density. A mascara brush with softer, more numerous bristles has been generally thought to be well suited for applying mascara but less well suited for combing out clumps and separating lashes. Conversely, a brush with stiffer, fewer bristles has been thought to be well suited for combing and separating lashes but less well suited for applying mascara to lashes. While a separate brush can be used for each function, i.e., a soft brush for application and a stiff brush for combing, a single brush that can both apply mascara and comb out clumps would be preferred for the convenience of the user. An example of a brush said to provide good application and combing characteristics is shown in U.S. Pat. No. 5,238,011 to Gueret. The Gueret patent discloses bristles made of a soft material having a shore hardness of 20A to 40D (as noted above, a conventional bristle typically has a durometer of over 85D), and a large diameter in a range of 0.004 inch to 0.014 inch (4 to 14 mil) (0.10 to 0.35 millimeter). As disclosed by Gueret, the diameter is said to be sufficiently large to prevent too high a degree of suppleness. The resulting brush is said to have the same degree of suppleness or softness as a conventional softer brush.
- Nevertheless, there can be a perception of bristle hardness to the mascara user. In many prior art brushes, the prior art approaches have not provided a brush with a combination of all the desirable features for a mascara brush—a soft bristle feel, combined with bristle stiffness suitable for high viscosity mascaras, while still providing both a good combing effect as well as high mascara loading.
- A method of manufacturing a mascara brush provides a mascara brush with bristle fibers that are split into numerous fragments. The mascara brush is made with bristle fibers having longitudinal voids. The brush is then conditioned by passing a rotating splitting tool along the body of the mascara brush. The splitting tool splits the bristle fibers into numerous bristle fragments. The conditioned brush is softer to the touch than the original mascara brush. The conditioning can be applied to the entire brush or one or more zones of the brush. The conditioning can be shallow, so that only the bristle tips are conditioned, or deep, so that a substantial length of the bristle is conditioned. The conditioned bristles comprise about two to ten bristle fragments formed from each original bristle, more typically, about two to six bristle fragments formed from each original bristle.

FIG. 8 is an illustration of the process of the invention. - Referring now to
FIG. 1 , a mascara applicator brush, designated generally byreference numeral 10, is shown. The brush is intended for use in a typical mascara bottle (not shown) with an opening into which thebrush 10 is inserted. - The
brush 10 is comprised of a central twistedwire core 12 containingbristles 14. Thecore 12 is a twisted wire core typically made by forming asoft metal wire 16 into a “U” shape. A plurality ofbristles 14 are placed between thesegments 18 ofwire 16. Thewire segments 18 are then twisted about the longitudinal axis to clampbristles 14 at approximately a midpoints of thebristles 14. The bristle ends extend radially from the twistedwire core 12.Core 12 has alower end 20 connected to a shaft, and anupper end 24 opposite thelower end 20. Thelower end 20 of thecore 12 is connected to a handle by way of the shaft, however, thelower end 20 of the core 12 could alternatively be attached to another structure such as a bottle cap. - Referring now to
FIG. 2 , at least some, and preferably, all the bristles 14 (or the filament from which they are made) are hollow in cross-section, at least at theirends 26, and preferably along their entire length. The hollow cross-section is provided by having from one to fourlongitudinal voids 28. Thebristles 14 may thus have asingle void 28 or multiple, radiallyadjacent voids 28. Each void 28 may extend through the cross-section continuously along the length of each bristle 14, or may be provided in the cross-section at spaced intervals along the length of each bristle 14, or only at theends 26 of the bristle. Thebristles 14 may be round in cross-section, or have other cross-sectional shapes, such as oval or triangular. In the preferred embodiment, as shown inFIG. 2 , thebristles 14 may be triocular, e.g. have threevoids 28 running the length of the bristle. -
Bristles 14 are typically made by cutting short segments from spools of filaments. The preferred materials for making the bristles are nylon filament or polyester filament. In one embodiment of the invention, the bristles preferably have a diameter of from 0.010 inch to about 0.016 inch (10 mil to 16 mil). More preferably, in this embodiment, the diameter of thebristles 14 will be 0.011 inch to 0.013 inch (11 mil to 13 mil), most preferably, about 0.11 inch (11 mil). As noted, the filaments may be round or may have non-circular cross-sectional shapes, thus, the term “diameter” as used herein is intended to mean the maximum distance between any of the possible opposite positions on the outer surface of abristle 14. In the above mentioned embodiment, the bristle density is in the range of 8 to 20 bristles per turn; more preferably 10-15 bristles per turn, and most preferably 12-14 bristles per turn. The filaments from which thebristles 14 are made can be selected based on their hardness. In this embodiment, the filaments may, if desired, be fairly soft, for example, the duPont “Supersoft” fibers having a durometer of between 62 Shore D and 82 Shore D can be used. However, due to the conditioning process which gives a feel of softness, even much harder filaments can be used, including filaments having a durometer in the range of about 92 Shore D hardness to 120 Rockwell R; more preferably about 100 to 120 Rockwell R; most preferably about 103 to 108 Rockwell R. - The bristle ends 26 of the mascara brush are conditioned to provide a softer feel to the bristle ends 26. The bristle ends 26 are conditioned by splitting them, either around the outer entire surface of the brush as in
FIG. 1 , or only in selected zones of the outer surface of the mascara brush. For example, as illustrated inFIG. 4 , the conditioning of the brush can be on one side of the brush outer surface (e.g. a zone comprising from about 45° to about 180° of the brush exterior circumference); or as illustrated inFIG. 5 , on different sides of the brush exterior surface (e.g. two oppositely positioned zones, each zone being from about 45° to about 90° of the brush exterior circumference). - As shown in
FIG. 8 , the bristle ends 26 are conditioned by slitting with aspinning wire wheel 60, or alternatively, by sharp metal knife blades mounted on a rotating spindle. The conditioned ends 30 of the bristles, as shown inFIG. 3 , are split into many fingers, which provide enhanced mascara holding and application to eye lashes, along with a soft feel to the touch. - In a preferred process for conditioning mascara brushes in accordance with the invention, an
indexing dial plate 62 holds 8collet mechanisms 64. Each collet mechanism is suited to hold amascara brush 10. Mascara brushes are loaded to thedial plate 62, rotated to a conditioning station, then released when conditioning is completed. At theconditioning station 66, the brush is held in place by a pin that holds the free upper end of the brush, and the collet mechanism, which hold the lower end of the brush.Wire wheel 60 is mounted on an electric motor, which causes thewire wheel 60 to rotate at between about 500 to about 3000 rpm. Preferably, thewire wheel 60 has a diameter of 4 inches and a width of 0.5 inch. In the preferred embodiment, the axis of themascara brush 10 and the axis of therotating wire wheel 60 are parallel, and therotating wire wheel 60 can index back and forth to condition along the length of the body of themascara brush 10. However, it is also possible to position the axis of the rotating wire wheel at 90 degrees to the axis of the mascara brush and move therotating wire wheel 60 along the body of thebrush 10. - The
wire tips 68 of thewire wheel 60 engage theends 26 of thebristles 14 of the mascara brush and tear and split many of the ends of thebristles 14 into two or more thinner bristle fragments 32. The possible range for generating bristlefragments 32 is about two to ten bristlefragments 32 for each original bristleend 26. In the preferred embodiment, there will typically be about two to six bristlefragments 32 for each original bristle end 26 conditioned by the wire wheel process. However, not all bristles 14 in a conditioned zone will be conditioned to the same extent. Some bristles 14 may be unaffected. Some may be split into 2 bristle fragments 32. Some may be split into six bristlefragments 32. The average number of bristle fragments 32 will be in the range of about 2 to about 3.8 bristle fragments per original bristle end. In one embodiment, the average number of bristle fragments 32 was about 2.9 bristlefragments 32 per original bristleend 26. - It should be noted that the conditioning can be applied principally to the tip ends of the
bristles 14, as shown inFIG. 6 , or alternatively, can be applied to the entire length of a bristle 14 that extends from the twistedwire core 12 as shown inFIG. 7 . However, the portion of thebristle 14 fiber gripped by themetal wire 16 of thebristle core 12 will usually remain intact and unaffected by the conditioning process. In the first mentioned approach, where the conditioning is applied to the tip ends only, the conditioned zones of the resultingmascara brush 10 will be of the type used for volumizing bulk, but with soft bristle tips. In the second mentioned approach, the conditioned zones will have a softer feel as a substantial portion of thebristle 14 will have been split. - The mascara brush of the invention provides a brush with a new and unique feel. While the invention has been described and illustrated as embodied in preferred forms of construction, it will be understood that various modifications may be made in the structure and arrangement of the parts without departing from the spirit and the scope of the invention recited in the following claims.
