Abstract: A cosmetic applicator with a column core applicator tip for retaining and applying a volume of cosmetic material. The column core applicator tip can have a column shape with a substantially continuous, cylindrical outer surface, and cosmetic applicator material, which can comprise flocked bristles, is applied to envelop the column core applicator tip. A cosmetic product reception indentation, which could comprise a supplemental product tube with a body portion within the applicator tip or a distal end cup, is disposed in an end face of the column core applicator tip, and that end face can be disposed at a miter angle. The supplemental product tube can have a length of at least one-half of the length of the body portion of the column core applicator tip.

Abstract: A cosmetic dispenser with a bottle and an applicator wand retained for slidable extension and retraction relative to the bottle. The applicator wand can be slid from a retracted position wherein a cosmetic applicator is retained within the bottle and an extended position wherein the cosmetic applicator projects through an aperture at a distal end of the bottle. A lateral dividing structure, which can be formed by an adapter insert and a rear seal, slidably receives the applicator wand and divides the inner volume of the bottle into a distal inner volume and a proximal inner volume. A laterally disposed distal wiping wiper with a plurality of radial slits can wipe a distal end of the cosmetic applicator, and a side wiping wiper with an inner throat can wipe a peripheral portion of the cosmetic applicator. A cap with a plug can matingly engage the side wiping wiper.

Abstract: A brush assembly with an applicator rod, a brush sleeve with a tubular core member and a plurality of bristles, a rod hole in the distal end of the applicator rod, and a rivet for being received into the rod hole to retain the brush sleeve. A peripheral retaining wall can retain and protect a proximal end of the brush sleeve. The brush sleeve can have radially projecting, diamond-shaped bristles and can be slidably received over a body portion of the rivet or over a support stem forming a distal portion of the applicator rod. The body portion of the rivet or the support stem can have a non-circular cross section or an arcuate longitudinal profile to induce the brush sleeve to have the non-circular cross section or acruate longitudinal profile. A method for producing brush assemblies can produce brush assemblies with brush sleeves of varied cross sections.

Abstract: A cosmetic applicator with disparate material application zones and a backwipe return for permitting the achievement of multiple cosmetic material application effects with a single applicator and for permitting the return of backwiped cosmetic material to a cosmetic bottle. The applicator has a wire core formed from first and second wire segments twisted into a helical configuration to form a plurality of coils. A plurality of radially disposed bristles are retained by the wire core to form a brush head. Multiple distinct bristle zones of different bristle types exhibit distinct material application properties in a single cosmetic applicator. Backwiped cosmetic material can be returned to the cosmetic bottle by a sloped shoulder at a proximal end of an applicator rod in combination with a cosmetic material passageway in a sloped facing surface of a flexible inner ring of a wiper.

Abstract: A cosmetic applicator brush with a core and bristles retained by the core to form a brush head. The brush head has a cross section with first and second lobes separated by first and second feed grooves. Each feed groove has first and second legs that terminate in a base portion, and each lobe has a first and second application surfaces formed in part by legs of adjacent feed grooves and an arcuate peripheral application surface between and contiguous with the first and second application surfaces. The application surfaces of the lobes can be arcuate, and the surfaces can cooperate to define a smooth bulbous surface. The lobes can have widths of approximately 65 percent of the effective diameter between central portions of the peripheral application surfaces, and the feed grooves can be separated by a distance approximately 10.5 percent of the effective diameter of the brush head.

Abstract: A cosmetics brush has an applicator rod with a molded polymer applicator core at the distal end thereof, the applicator core having a substantially circular cross-sectional shape, a plurality of spaced apart tuft-receiving blind openings are formed in the applicator core in selected locations thereon and a plurality of bristle tufts each formed of a plurality of bristle fibers folded into a U-shaped configuration about an anchors are received in a respective one of the tuft-receiving blind openings, the anchors extending across the tuft-receiving blind openings and having ends embedded in the applicator core to secure the bristle tufts therein. The blind openings and bristle tufts may be deployed in a variety of configurations, including rows and spirals, and there may be multiple rows and spirals. The bristle tufts may have different bristle fibers.

Abstract: An improved mascara brush has a typical twisted wire core containing bristles having a double lumen cross-section. The bristles are generally circular in shape, and hollow, with a dividing web across the midpoint of the bristle, thereby defining two longitudinal lumens extending along the length of the bristle. In other embodiments, the bristle is oval, square, rectangular or another polygonal shape.

Abstract: A mascara brush and method of manufacture thereof 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 wire wheel over the bristle fibers . The wire wheel 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.

Abstract: An improved mascara brush has a typical twisted wire core containing bristles of Z-Shaped cross-section. The Z-shaped cross-section may be a conventional Z-shape; or it may be square or rectangular thereby defining a cross-section of discontinuous square, diamond or polygon shape with a connecting web; or it may be circular or oval thereby defining a cross-section of discontinuous circular shape with a connecting web. In either embodiment the cross-sectional shape effectively creates two longitudinal voids extending along the length of the bristle.
