In embodiments, the present invention is directed to a brush or applicator including an ergonomic handle to facilitate precision brushing of a surface and/or other manipulation of a surface with a brush portion/application portion. While exemplary embodiments are described herein with respect to a brush, it will be understood that the handle portion configurations described herein may be used with a different type of cosmetic applicators/implements, for example, a brush, comb, wand, stylus, sponge, silicone or a doe foot, to name a few.
It will be further understood that the handle portion configurations described herein may also be used with one or more of the brush and applicator types and configurations mentioned below or one or more of the following cosmetic applicators/implements for, for example, makeup mist, skincare mist, lipstick, lip crayon, lip gloss, lip liner, lip exfoliator, eyeliner pencil, liquid eyeliner, cream eyeliner, powder eyeliner, eye crayon, mascara, foundation cream, foundation serum, foundation powder, liquid foundation, eyeshadow powder, eyeshadow liquid, eyeshadow palette, eyeshadow cream, powder pressed, loose powder, blush cream, liquid blush, blush powder, bronzer cream, bronzer powder, liquid bronzer, highlighter cream, liquid highlighter, highlighter powder, shimmer powder, oil, primer, moisturizer, serum, lotion, cleanser, eyebrow pencil, eyebrow wax, eyebrow powder, eyebrow cream, eyebrow mascara, concealer pencil, liquid concealer, concealer cream, palette, or a compact, to name a few additional examples.
With reference to FIGS. 2-8 , a brush according to an exemplary embodiment of the present invention is illustrated and generally designated 100 . Brush 100 may include a brush portion 110 and a handle portion 120 , as shown.
Brush portion 110 may be an applicator member configured to engage a desired surface such as skin, hair (e.g., eyelashes or eyebrows), or a display template, for example, to by adding, removing, and/or manipulating a cosmetic material. In embodiments, brush portion 110 may include a polymeric material, e.g., synthetic fiber such as acrylic or plastic, that may have a desired rigidity and capacity for absorption of other materials, for example, bristles, fibers, cloth, pledgets, or foam, to name a few. In embodiments, brush portion 110 may be formed of a different type of fiber, such as natural or organic fibers, to name a few. Brush portion 110 may be configured in accordance with a desired type of surface engagement, for example, brush portion 110 may have a desired bristle count, length, density, or absorption capacity, to name a few. In embodiments, brush portion 110 may include a different type of material, such as a wand, comb, stylus, sponge, silicone or a doe foot. In embodiments, brush portion 110 may have an axial length of between and including 25 mm and 35 mm. In other exemplary embodiments, brush portion 110 may have a shorter or longer axial length, such as the lengths shown in Table 1 below.
In embodiments, brush portion 110 may be a solid color, such as black, white, pink, rose gold, brown, or a metallic color, such as gold, silver, rose gold, gun metal, or pearl, to name a few, or brush portion 110 may be multicolored. In embodiments, brush portion 110 may also include one or more visual indicators to facilitate use. For example, brush portion 110 may include a color gradient that shifts from a darker color closer to handle portion 120 to a lighter color further away from handle portion 120 . Such a visual configuration of brush portion 110 may aid a user in identifying the presence of cosmetic material on brush portion 110 during use of brush 100 . In embodiments, brush portion 110 may be visually configured to have a graduated configuration from a gray color closer to handle portion 120 (and ferrule 140 , when present) to a white color further away from handle portion 120 (and ferrule 140 , when present). In other exemplary embodiments, a color gradient of brush portion 110 may feature a graduated change of a different color or colors other than gray and/or white, such as a graduated change from a darker color closer to handle portion 120 to a lighter color further away from handle portion 120 . In embodiments, brush portion 110 may be visually configured, e.g., colored, to contrast against a cosmetic material being applied. In this regard, a user is afforded more precise control over brush 100 by being afforded a contrasting view of cosmetic material to be applied against a contrasting background. In embodiments, other types of visual indicia, for example, bands, marks, or striations, may be present on brush portion 110 to assist in fine control over engagement of brush 100 against a surface.
Handle portion 120 , as shown, may include a handle 130 and a ferrule 140 interconnecting the handle 130 and brush portion 110 . In embodiments, brush 100 may be devoid of a ferrule 140 , with brush portion 110 directly affixed to handle 130 .
Ferrule 140 supports brush portion 120 , and may be coupled to brush portion 120 by, for example, adhesion, crimping, clamping, interweaving, or friction fit, to name a few. In embodiments, the tightness of coupling of ferrule 140 to brush portion 110 is a function of the density of brush portion 110 . For example, a brush portion 110 having a greater number of bristles may require a greater crimp on ferrule 140 to maintain a secure engagement of brush portion 110 with ferrule 140 . In embodiments, brush portion 120 and ferrule 140 may be detachable from one another, e.g., so that replacement or alternative brush portions can be coupled with handle portion 120 . In embodiments, ferrule 140 may be detachable from handle portion 120 so that ferrule 140 and/or brush portion 110 may be replaced with respect to handle 130 .
In embodiments, ferrule 140 may be configured to support a variety of brush and applicator types and configurations, for example, a powder brush, a concealer brush, a contouring brush a bronzer brush, a foundation brush, a blush brush, a Kabuki brush, a blending brush, an eye brush, a crease brush, an eye liner brush, a face brush, a defining brush, a lip brush, an eye shadow brush, a stipple brush, a smudge sponge, a brow comb, an eyelash wand, or an eyebrow wand, or one of the cosmetic applicators/implements mentioned above, to name a few. Examples of brush types and configurations can be seen in FIGS. 9-69 . In embodiments, an applicator may have a cap (e.g., lipstick) that fits over the brush or other applicator.
Ferrule 140 may be formed of a suitable material configured to support brush portion 120 , for example, a polymeric material, a composite material, and/or a metallic material, to name a few. In embodiments, ferrule 140 may be formed at least partially of a metallic material with a smooth, e.g., brushed or polished, finish. In embodiments, ferrule 140 may be formed at least partially of a non-metallic finish (e.g., a black finish).
As shown, ferrule 140 may be a conic section, e.g., having a circular axial cross-section that tapers therealong, and which terminates at a point such that a side profile of the ferrule 140 is trapezoidal. In embodiments, ferrule 140 may taper such that a diameter of ferrule 140 reduces between and including a length of 26 mm and 1 mm in an axial direction. In embodiments, ferrule 140 may have an overall axial length of between and including 35 mm and 55 mm. Such a configuration may present a surface for engagement of the brush 100 by a user, for example, the thumb and index finger of a user, to facilitate fine manipulation of the brush portion 110 against a surface. In embodiments, ferrule 140 may have a different configuration, for example, a triangular, rectangular, or elliptical cross-section, and/or a different side profile, to name a few. The opening and diameter of ferrule 140 is affected by the volume of brush material of brush portion 110 to be held. In general, the greater the amount of brush material to be held, the wider the opening. Conversely, when a lesser amount of brush material is to be held, the opening of the ferrule may be tapered inwardly, as shown in FIGS. 16-22 .
Still referring to FIGS. 2-8 , handle 130 will be described in detail. Handle 130 , as shown, may be an elongate member with a triangular cross-section. In embodiments, the triangular cross-section may have a shape of an equilateral triangle, and may include vertices that are curved or beveled to avoid sharp corners. Accordingly, handle 130 presents three separate outer surfaces and edges for engagement by a user such that fine manual control of brush 100 is afforded to the user. In this regard, handle 130 may be formed of a material that is sufficiently rigid to be directionally manipulated by a user's fingers and/or hand. In embodiments, handle 130 may be formed of one or more of, for example, a polymeric material (such as glass or plastic), a composite material, or a metallic material, to name a few. In exemplary embodiments, handle 130 may be formed of an at least partially transparent material, including a fully transparent or a translucent material. Accordingly, handle 130 may be selected from a material having a high light transmissibility, e.g., configuration to transmit a percentage of incident light therethrough, such as between 75% and 95% of incident light. In embodiments, handle 130 may be formed of a polymeric material such as glass or plastic. Such transparency of handle 130 may reduce the occurrence of shadows cast by handle 130 on a target surface and/or may allow a user to at least partially view an environment through handle 130 . In embodiments, handle 130 may be opaque and display one or more colors, such as gold, silver, rose gold, gun metal, pearl, and/or other metallic colors, or a non-metallic color such as black, grey, white, pink, rose gold, brown, to name a few. In embodiments, handle 130 may be iridescent and/or may include glitter, pearls. or other decorative features, and may include printed text or graphics.
Handle 130 may have a length sufficient to afford a user with a desired grip of brush 100 . In embodiments, handle 130 may have a length between and including, for example, 90 mm and 100 mm. Such length of handle 130 may afford the user with dexterous control of brush 100 , for example, by allowing the user to tilt brush 100 using portions of handle 130 as a lever. A user is also afforded the option of grasping portions of handle 130 along its length that is most comfortable for his or her grip. In this regard, handle 130 is configured for use by a variety of users.
As shown, handle 130 (or a segment thereof) may be tapered, e.g., having a cross-sectional area that decreases therealong in a direction extending away from brush portion 110 . For example, handle 130 may decrease in cross-sectional diameter and area along a range between and including 8 mm and 5 mm. (As used herein, the cross-sectional diameter of a triangular cross-section is measured from one vertex of the triangle to a midpoint on the side of the triangle opposite that vertex. An example of a cross-sectional diameter is shown, for example, by dashed line 160 in FIG. 57C .) In embodiments, the cross-sectional diameter of handle 130 may taper at a rate of between and including 0.01 mm and 0.2 mm per unit mm (i.e., the taper is within a range of 0.01 mm and 0.2 mm per unit mm) along the length of handle 130 , or a segment thereof. In embodiments, the cross-sectional diameter of handle 130 may taper at a different rate per unit mm along the length of handle 130 . Such taper of handle 130 may provide the user with a comfortable grip of brush 100 , for example, by providing a relatively larger surface area for fine engagement, for example, by a user's fingers, and an increasingly narrower section of handle 130 that can rest comfortably on a user's wrist, palm, and/or thenar space without requiring the user to tense the muscles thereof to maintain a grip on handle 130 .
Handle 130 may also include an end 132 that is blunted, e.g., having a flattened or beveled surface. Such a configuration of end 132 may facilitate the free movement of end 132 by a user without worry as to possible scratching or poking of the user or a surface engaged by brush 100 . End 132 may also be configured to support brush 100 in a standing configuration on a flat surface. In embodiments, end 132 may be configured for engagement with, for example, a storage or display implement for brush 100 .
Referring to FIGS. 9-69 , various embodiments of cosmetic brushes with handles according to the present invention are illustrated. As shown, such embodiments according to the present invention may have a variety of configurations of overall lengths, brush portion lengths, ferrule lengths, handle lengths, and tapering handle cross-sectional diameters, with examples provided in Table 1 below at least for the embodiments of FIGS. 24A-59C .
