Abstract

Cosmetics brushes particularly suitable for applying mascara include a plurality of multi-fiber bristles deployed extending from a core, at least some of the multi-fiber bristles including a plurality of individual fibers in supportive interengagement. In one embodiment, a central support fiber has smaller and less stiff additional fibers braided or woven thereabout. The additional fibers may themselves be braided bundles of microfiber. In another embodiment, thin fibers are constrained and supported within a hollow support fiber, which may be a fiber with a C-shaped cross section and an entry slot to the hollow central portion. In another embodiment, a spiral support fiber is spirally wound around a plurality of smaller diameter fibers. In a further embodiment, a plurality of fibers are braided together to form a multi-fiber bristle, and some of the fibers may be bundles of microfibers. In these cosmetics brushes, fibers may be selected and mixed to achieve desired performance.

Description

    FIELD OF THE INVENTION
  • The invention herein relates to cosmetics and mascara brushes having engineered multi-fiber bristles deployed extending from a core. [0001]
  • BACKGROUND OF THE INVENTION
  • This application claims benefit of our U.S. Provisional Patent Application Serial No. 60/393,666, filed Jul. 3, 2002. [0002]
  • Cosmetics brushes are used to carry cosmetics to the point of application and to apply the cosmetics in a controlled manner. The cosmetics may be for a variety of purposes, such as lip gloss, eye shadow, eyeliner, eyebrow make-up, and mascara. The ability of a brush to carry and apply cosmetics is largely determined by its bristles. [0003]
  • Mascara brushes in particular have two primary functions; namely, they apply mascara to the eyelashes and they comb the eyelashes to provide separation. The selection of the bristles of the brush, as well as their density, are important factors in how well the mascara brush can perform these two functions. Many times the two functions are not synergistic or even complementary, and therefore compromises must be made in selecting the bristles for the brush. [0004]
  • Various types of bristles have been used in mascara brushes. The primary choice for bristles has been synthetic polymer materials, generally in a diameter range of approximately 0.003 inches to approximately 0.006 inches. These materials have included nylon, polyesters and various blends and composites of polymers, often chosen so that the mascara product would adhere to the bristles for carrying the mascara product to the eyelashes and applying it. [0005]
  • Certain specialty bristles have been developed with various cross-sectional variations, such as quadrilobal bristles, trilobal bristles, and bristles having a “C” shaped cross section which might also be described as hollow bristles each having a longitudinal slot. These specialty bristles have a good ability to carry product, due to their special cross-sectional shapes, and also tend to spread out and form a bushier more even brush when deployed between a twisted wire core. Hollow bristles are also popular in mascara brushes, in large part because of their ability to form a bushy brush. [0006]
  • Mascara brushes have also been proposed with mixtures of different types of bristles, wherein the bristles are independently deployed along a twisted wire core. Schrepf U.S. Pat. No. 4,861,179 is an example of such a mascara brush, in which different types of bristles are randomly intermingled along a twisted wire core, and wherein the bristles are independent of each other and stand alone in extending from the twisted wire core. Even though some of the bristles may be softer and more flexible than others, they are limited in this regard by the requirement that they have sufficient rigidity to stand on their own. Therefore, a very fine bristle otherwise advantageous for applying mascara cannot be used in a mascara brush of this type. [0007]
  • Fitjer U.S. Pat. No. 6,443,162 discloses a mascara brush with bristles formed of multiple fibers that are fixed together along a substantial length of the fiber. The fibers are separated at the ends of the bristles. Thus, the sides of the bristles resemble a conventional bristle of non-circular cross-section, and the number of tip ends is limited. [0008]
  • Formulas for mascara are also being improved, but present brushes are not always capable of advantageously applying the new formulations. Other cosmetics brushes have similar requirements. For example, eyebrow brushes must be able to apply product and comb eyebrows, and eyebrow brushes must be able to carry product and place the product in the desired position. [0009]
  • It is clear from the above considerations that it would be desirable to enhance the capability of a mascara brush to apply mascara, as well as provide for good combing, and to improve brushes for applying other cosmetics as well. [0010]
  • SUMMARY OF INVENTION
  • It is a principal object of the invention herein to provide an improved cosmetics brush. [0011]
  • It is also an object of the invention to provide a cosmetics brush that may accomplish combing and curling when applying or spreading cosmetics products. [0012]
  • It is an additional object of the invention to provide an improved mascara brush well adapted to both apply mascara and to comb and separate eyelashes. [0013]
  • It is a further object of the invention to provide a mascara brush, incorporating multi-fiber bristles in a manner that enhances both application of mascara and the combing and separation of eyelashes. [0014]
  • It is another object of the invention to provide a cosmetics brush that is adaptable to a variety of cosmetics formulations. [0015]
  • It is also a principal object of the invention to provide engineered multi-fiber brushes for use in cosmetics brushes, and especially mascara brushes. [0016]
  • In carrying out the foregoing objects of the invention, a cosmetics brush, and particularly a mascara brush, is provided having a plurality of bristles wherein the plurality of bristles are comprised of multiple fibers. The multiple fibers are deployed in supportive interengagement to form the multi-fiber bristles, and the multi-fiber bristles are deployed extending from a core. A twisted wire core is provided in preferred embodiments. [0017]
  • According to additional aspects of the invention, the multi-fiber bristles include different kinds of fibers. Some of the fibers in each multi-fiber bristle may be stiffer than others, thicker than others, or both, and the fibers may be of different materials and have different characteristics. Multi-fiber bristles are provided wherein some of the fibers are stiff and self-supporting, and wherein other fibers placed and retained together with the self-supporting fibers are substantially limp and are supported by the stiffer fibers. [0018]
  • In further aspects of the invention, the multi-fiber bristles are comprised of a central support fiber supporting a plurality of thin fibers substantially surrounding the central fiber. In accordance with more specific aspects, fibers formed of microfiber may be braided or woven about the exterior of the central support fiber. Tip ends of the microfiber may form tufts. Alternatively, a stiff support fiber may have a hollow interior, with or without a longitudinal entry slot, and microfibers or other thin fibers are supported within the hollow interior, with their tip ends extending outwardly from the tip ends of the stiff support fiber. [0019]
  • In another aspect of the invention, the multi-fiber bristles comprise a core of thin fibers, which may be microfibers, and a spiral-wrapped outer support fiber, with the thin fibers protruding from the ends of the outer support fiber and along the spiral slot defined by the spirally wrapped outer support fiber. [0020]
  • Also, in accordance with other aspects of the invention, the multi-fiber bristles are a plurality of fibers braided together. In some instances, some of the fibers braided together are themselves twisted or braided groups of finer fibers, which may be microfibers, providing tufted tip ends. [0021]
  • The exposed portions and ends of the thin fibers or microfibers are especially well adapted to carry and apply mascara, and the multi-fiber bristles are also useful in combing eyelashes. [0022]
  • In carrying out the foregoing objects of the invention, the engineered multi-fiber bristles may be used with various core structures and in brushes for cosmetics other than mascara. [0023]
  • The foregoing and other objects and features of the invention will be readily understood by those skilled in the art, and will also appear in more detail in the following description of the preferred embodiments and the claims, taken together with the drawings. [0024]

  • DESCRIPTION OF PREFERRED EMBODIMENTS
  • FIG. 1 illustrates a cosmetics brush, namely, a first mascara brush [0030] 10, according to the invention herein. The mascara brush 10 generally comprises a core 12, which may be formed of two wires 14 and 16 twisted together, as is well known in the art, or may be another core. The mascara brush 10 further incorporates a plurality of multi-fiber bristles 20, 21, 22, with additional multi-fiber bristles being incorporated in the mascara brush 10 but not being shown for sake of clarity. The multi-fiber bristles 20, 21, 22 are captured between the two wires 14 and 16 of the twisted wire core 12, and extend generally radially outward therefrom.
  • Multi-fiber bristle [0031] 20 has a central support fiber 24 with tip ends 26 and 28. The support fiber 24 has a relatively large diameter and is sufficiently stiff to flexibly support the multi-fiber bristle 20 in its radial extension from the twisted wire core 12, including during application of mascara and combing of eyelashes.
  • The multi-fiber bristle [0032] 20 also has a plurality of additional fibers 30, 31, 32, etc., that are braided, woven or otherwise supportively interengaged with and surrounding the central bristle 24. The additional fibers 30, 31 and 32 are smaller diameter, more limp fibers and are substantially supported by the central support fiber 24. The additional fibers 30, 31 and 32 provide a braided or woven outer surface area along the length of the central support fiber 24, except that adjacent to the tip ends 26 and 28 of the central support fiber 24, the braided or woven areas of the additional fibers 30, 31, 32 are unraveled to present a plurality of tip ends of the exterior fibers 30, 31, 32, etc. These tip ends are illustrated in FIG. 1 as tip ends 36, 37 and 38. In some instances, these tip ends are sufficiently numerous as to form tufts surrounding the support fiber 24. The other multi-fiber bristles 21, 22 and those not shown are similarly constituted, although they may be mixed with yet other bristles, if desired. The other bristles may include solid bristles, hollow bristles or other known bristles.
  • The multi-fiber bristles [0033] 20, 21, 22 and therefore the mascara brush 10 have unique functional characteristics. The exterior of the multi-fiber bristles 20, 21 and 22 have the braided or woven areas described above, and therefore provide a textured surface that is well suited to accumulate mascara from a mascara container and to apply mascara. The tip ends 36, 37, 38 of the fine fibers 30, 31, 32 are well positioned for applying and spreading mascara onto eyelashes, when the outer surface of the mascara brush 10 is stroked lightly over the eyelashes, i.e. when the tips of the multi-fiber bristles are engaged on the eyelashes.
  • The multi-fiber bristles [0034] 20, 21, 22 as a whole are also well adapted to act as a comb when the mascara brush 10 is more deeply engaged with the eyelashes, and more particularly with individual eyelashes positioned between the multi-fiber bristles which therefore act similarly to teeth of a comb. Further, the braided or woven surface areas of the multi-fiber bristles 20, 21, 22 may apply additional layers of mascara as the mascara brush 10 is used for combing.
  • The central support fiber [0035] 24 of each multi-fiber bristle of the mascara brush 10 may be a solid nylon fiber having a diameter in the range of about 0.003 inches to about 0.012 inches. In the mascara brush 10, the central support fiber 24 is nylon and is about 0.005 inches in diameter. The central support fiber may also be a hollow fiber, and may be of material other than nylon, such as a polyester or other known bristle material. The additional fibers, 30, 31, 32, etc., may be made of small diameter monofilament or of bundles of fine microfiber, with the additional fibers having a diameter of about 0.001 inches or in the range of about 0.0005 to 0.0015 inches. When microfiber is used to constitute the additional fibers 30, 31, 32, etc., the microfibers may themselves be bundled and/or twisted to form the additional fibers 30, 31, 32 before the additional fibers are braided or woven about the central support bristle 24. In mascara brush 10, there are four fibers 30, 31, 32, etc., braided about support fiber 24, each additional fiber being itself made from about 20 nylon microfibers, i.e. of thin filaments. The fibers 30, 31, 32 are 70-denier, at approximately 70 picks per inch. The microfiber has an irregular cross section, wherein the microfiber tends to interlock into one fiber 30, 31, 32, etc., especially when twisted. The overall diameter of the preferred multi-fiber bristles 20, 21, 22 is about 0.009-0.011 inches, although it may be larger or smaller.
  • Other materials may be used for the additional fibers [0036] 30, 31, 32, etc. The materials may include other polymers, such as polyesters and urethanes, and may also include natural fibers such as linen, cotton and silk. An elastic component may also be included, if desired. It will also be appreciated that additional fibers of different material may be used to form a multi-fiber bristle, with the materials being chosen to achieve a bristle that complements the cosmetics. Thus, the cosmetics brush 10 may be engineered for specific applications.
  • The multi-fiber bristles [0037] 20, 21, 22, etc. may be deployed in a density from about 10 to 80 multi-fiber bristles per turn of the twisted wire core 12, although the mascara brush 10 has a much higher total fiber count because of the composite nature of each of the multi-fiber bristles. It will be appreciated that the mascara brush 10 is mounted on an applicator rod and utilized as part of a mascara container, all in accordance with known methods and apparatus for applying mascara.
  • FIG. 2 illustrates another mascara brush [0038] 50 according to the invention herein. It also has a twisted wire core 52 fabricated of two wires 54 and 56, which capture a plurality of multi-fiber bristles, including multi-fiber bristles 60, 61 and 62 shown in FIG. 2. It will be appreciated that the mascara brush 50 has additional multi-fiber bristles, not shown, and may have other bristles interspersed with the multi-fiber bristles, as desired.
  • The multi-fiber bristle [0039] 60 has a first relatively large diameter support fiber 64, which is sufficiently strong to support the multi-fiber bristle 60 in its entirety. The support fiber 64 has a “C” shaped cross section with a hollow interior and a slot opening 66 extending along the length of the fiber 64 between its tip ends 68, 69. The multi-fiber bristle 60 also has a plurality of relatively thin, small diameter central additional fibers 70 which generally are not able to support themselves, but which are positioned in supportive interengagement within the hollow interior of the support fiber 64 and are surrounded and supported by the first bristle 64. The plurality of central fibers 70 have their tip ends, collectively designated at 72 and 74, extending beyond the tip ends 68 and 69 of the support fiber 64. These tips may form into tufts of fine fiber ends. The other multi-fiber bristles 61, 62, etc., are the same or similar to multi-fiber bristle 60, but may be mixed with other bristles to form brush 50.
  • The multi-fiber bristles [0040] 60, 61, 62 therefore provide multiple, fine diameter tip ends 72 and 74 for carrying and applying mascara to the eyelashes. This is achieved when the mascara brush 50 is lightly engaged with the eyelashes so that the eyelashes are presented to the tip area of the brush 50. When the mascara brush 50 is more deeply engaged with the eyelashes, the eyelashes become positioned between the multi-fiber bristles 60, 61, 62, which then serve to separate and comb the eyelashes.
  • The support fiber [0041] 64 and the corresponding support fibers of the other multi-fiber bristles may be fabricated of nylon, polyester, or other suitable polymer bristle material, and may have a diameter in the range of about 0.005 to about 0.015 inches. The support fiber may be extruded over the additional central fibers 70. The central fibers 70 may be polyester microfiber, and may have quite small diameters, on the order of 0.0005 inches or less. They may also be nylon or another polymer, or various natural materials. However, it will be appreciated that a smaller number of larger diameter central fibers 70 may be accommodated and utilized within the support fiber 64, and that the additional central fibers may be a mix of fibers of various materials and diameters. The multi-fiber bristles of mascara brush 50 may be provided in a range of about 10 to 80 multi-fiber bristles per turn of the twisted wire stem 52. The resultant mascara brush 50 is mounted at the end of an applicator rod and utilized in a mascara container, in accordance with known methods and apparatus in the art.
  • Another mascara brush [0042] 100 is illustrated in FIG. 3. The mascara brush 100 also has a twisted wire core 102 formed of two wires 104, 106 and a plurality of multi-fiber bristles 110, 111, 112, etc., captured by and extending from the twisted wire stem 102.
  • The multi-fiber bristle [0043] 110 is characterized by a support fiber 114 having tip ends 116 and 118. The support fiber 114 is a spirally configured strip, which defines a central opening 120 and a spiral slot 122 between adjacent portions of the strip. The central opening 120 is best seen on the corresponding support fiber 115 of multi-fiber bristle 111, where it is given number 121.
  • The support fiber [0044] 114 is wrapped about and supportively engages a plurality of central additional fibers 130, which are fine fibers of relatively small diameter such that the multi-fiber bristle 110 relies primarily on the support fiber 114 for its stiffness. However, the central fibers 130 do contribute to the stiffness and form of multi-fiber bristle 110 because they substantially fill the center opening and bridge the spiral slot 122.
  • The central fibers [0045] 130 have tip ends at 132 and 134 which extend beyond the tip ends 116 and 118 of the first support fiber 114. These ends may take the form of tufts. Also, portions of the central bristles 130 indicated at 136 and 138 protrude through the spiral slot 122 defined by the fiber 114, wherein portions of the fine diameter central fibers are presented along the length of the multi-fiber bristle 110.
  • The multi-fiber bristles [0046] 110, 111 and 112 provide for excellent application of mascara to eyelashes and also for combing and separation of eyelashes. The tip ends 132, 134 of the central fibers 130 and the protruding portions 136 and 138 of the central fibers serve to carry and apply mascara, and the overall stiffness of the multi-fiber bristles provide for good combing action. It will also be noted that during combing, the protruding portions 136 and 138 of the central fibers may incrementally add mascara for layering effects.
  • The support fiber [0047] 114 of the multi-fiber bristle 110 is fabricated of a thermoplastic material having good memory characteristic, so that it will retain its spiral configuration. It may have a diameter in the range of about 0.005 inches to about 0.020 inches. The central fibers are generally about 0.001 inches in diameter, and may be monofilament or bundles of a polyester microfiber or one of the other materials mentioned above. The central fibers 130 may be provided in lengths less than the entire length of the multi-fiber bristle 110, in that they are captured and supported by the support fiber 114, but are preferably longer to maximize the number of tip ends. Mixtures of fiber types may be used. It will be appreciated that the mascara brush 100 is mounted on an applicator rod for use in mascara containers of the known type.
  • With reference to FIG. 4, a mascara brush [0048] 150, according to the invention herein, is illustrated. It has a twisted wire stem 152, having two wires 154 and 156 twisted together, and the twisted wire stem captures a plurality of multi-fiber bristles 160, 161, 162, etc. The multi-fiber bristles 160, 161 and 162 are a plurality of different types of individual fibers 170, 172, 174, etc., braided together in supportive interengagement, wherein each of the individual fibers is selected to work with the other fibers to provide desirable characteristics of the multi-fiber bristle. The multi-fiber bristles may include monofilament fibers 170 of nylon, polyester or the like, generally having a diameter in the range of about 0.001 inches or less to about 0.002 inches or slightly more. The multi-fiber bristles may also include fibers 172, which may also be 0.001-0.002 inches in diameter and are each twisted, bundled or braided from multiple strands of smaller microfiber. They provide a large plurality of tip ends 173, to assist in carrying and applying mascara, i.e. the tip ends 173 are the ends of the multiple strands of microfiber that make up the fibers 172. Further, fiber 174 may be a small hollow fiber, and fiber 176 may have a unique cross section, such as quadrilobal, trilobal or C-shaped cross sections. These fibers and others may be variously incorporated in a multi-fiber bristle 160.
  • When the various fibers are braided together, they provide a multi-fiber bristle with a textured outer surface and with spaces or interstices throughout the cross-section of the bristle. The stiffness of the multi-fiber bristles [0049] 160, 161, 162 is established by the selection of individual fibers, and for instance, utilizing one or more solid fiber having a high stifffiess with respect to its diameter will maintain a desired stiffness of the overall multi-fiber bristle that also includes fibers made of twisted microfiber or the like.
  • The overall diameter of the multi-fiber bristles [0050] 160, 161 and 162 may be in the range of about 0.005 to about 0.020 inches and the multi-fiber bristles are deployed in a density of approximately 10 to 80 bristles per turn of the twisted wire stem 12.
  • It will be appreciated that the mascara brushes as described above are well adapted to apply mascara to eyelashes and to comb the eyelashes, in that the engineered combinations of fibers and the inclusion of some fibers or groups of fibers with tufted or flagged ends results in the multi-fiber bristles well adapted to carry mascara, while the thickness and stiffness of the multi-fiber bristles can be adjusted for good combing action. The inclusion of several types of fibers in the multi-fiber bristles permit the fabrication of a mascara brush with highly desirable characteristics and, more importantly, provides the designer of the mascara brush with numerous options for adjusting the characteristics for best performance with particular mascara products. [0051]
  • It will also be appreciated that these multi-fiber bristles are useful in other types of cosmetics brushes, wherein it is desirable to carry and apply cosmetics with fine fibers, but also desirable to have a sufficiently stiff bristle that the cosmetics can be accurately place, or to have combing capability. [0052]
  • Accordingly, the mascara brushes described above admirably achieve the objects of the invention. It will be appreciated that various changes be made by those skilled in the art without departing from the spirit and scope of the invention, which is limited only by the following claims. [0053]
