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.

Abstract: A mascara container has an elongated bottle with a continuous sidewall defining a product reservoir. The bottle has a threaded neck with an apertured wiper mounted thereon, providing access to the product reservoir. A cap is removably threaded onto the neck of the bottle, and a rod extends from the cap through the apertured wiper when the cap is secured on the bottle. The rod has a distal end positioned generally centrally with respect to the continuous sidewall, and a brush is mounted at the distal end of the rod. The brush has a first portion extending outwardly toward the continuous sidewall, and a second portion extending downwardly along the continuous side wall, at least said second portion of the brush having bristles deployed for sweeping product from the continuous sidewall of the elongated bottle as the threaded cap is removed from and replaced on the threaded neck of the bottle.

Abstract: A cosmetics container for storing and applying a product has a bottle having a neck defining a neck opening to an interior product cavity, the neck having threads on the exterior thereof. A neck insert is mounted in the neck opening, the neck insert including a side wall substantially conforming to the neck opening and providing access to the product cavity. The neck insert includes a dispenser wall deployed between the neck opening and the product cavity and the dispenser wall has at least one supply opening. A cap has interior threads for removably securing the cap on the bottle in a closed position by interengaging the threads on the neck. The cap having a stem extending into the neck insert and an applicator pad mounted to the distal end of the stem. The threads of the neck and the threads of the cap configured to support the cap on the neck prior to threaded engagement of the threads with the applicator pad spaced from the dispenser wall to define a dosing space therebetween.

Abstract: A mascara brush has a twisted wire core with radially extending bristles trimmed to a generally cross-sectional triangular shape. The apex is truncated to form an application surface and a feed groove extends inwardly from the base of the triangular shape, opposite the application surface. First and second combing surfaces flank the feed groove. A first side surface joins the first combing surface at a sharp comb edge and joins the application surface at a first application edge. A second side surface joins the second combing surface at a second sharp combing edge and joins the application surface at a second application edge. The application surface may also be rounded. The core may be curved to provide a convex or concave application surface. The various surfaces and edges provide a very versatile mascara brush.

Abstract: A mascara brush has a wire core securing bristles extending radially therefrom. The bristles are trimmed to define applicator bristles and bristles extending in a longitudinal profile comb deployed along the core, the profile comb being longer than the applicator bristles. The core is curved in a plane passing through the profile comb whereby bristles extending from the convex side of the curved core diverge and bristles extending from the concave side of the curved core converge. The profile comb has a flat comb surface extending across its width, and the comb surface longitudinally curves to generally conform to eyelashes. For applying quick drying building or curling mascara, the profile comb extends from the concave side of the curved core. For applying heavier defining mascaras, the profile comb extends from the convex side of the core. The brush has bristles along one inch of its length, the bristles being secured in approximately sixteen turns of the brush at a density of 45 to 65 bristles per turn.

Abstract: A cosmetics container has a bottle, a neck insert defining an entry opening and a wiper diaphragm mounted at the lower end of the entry opening. A cap has an applicator rod and applicator extending therefrom, for insertion into the bottle and withdrawal from the bottle with cosmetics. The wiper diaphragm defines a wiper orifice, and has a conical descending upper surface and a concave lower surface converging with the upper surface to create a thin edge peripherally surrounding the wiper orifice. The wiper diaphragm is fabricated of semi-rigid plastic which stretches and flexes to accommodate and seal to the applicator rod and which is rigid with respect to the applicator for wiping it. The concave lower surface conducts wiped cosmetics away from the orifice. The bottle includes a plastic liner. A modified wiper includes a radially segmented spill cover deployed across the wiper orifice, to prevent cosmetics from running from the bottle if it is tipped over while the cap is off.

Abstract: A cosmetics container includes a bottle defining a chamber for containing cosmetics, the bottle including a threaded neck, and a cap removably secured to the neck. The cap has an applicator rod for extending through the neck into the cosmetics chamber and applicator at the distal end of the rod for carrying cosmetics. A wiper has i) a sleeve mounted in the bottle neck, the sleeve defining an outlet through the neck from the cosmetics chamber, and ii) a conical wiper diaphragm extending from the sleeve across the outlet and descending into the cosmetics chamber below the neck. The conical wiper diaphragm defines a central wiper orifice for accommodating passage of the applicator rod and applicator and for wiping excess cosmetics therefrom as the applicator rod and applicator are withdrawn from the cosmetics chamber.

Abstract: A cosmetics applicator comprises a rod having a threaded portion on the distal end of the rod, and characterized by a plurality of feed channels extending along the length of the rod and transected the threads. The space between the transecting threads and the portion of the feed channel lying below the depth of the threads carries an additional reservoir of cosmetics, and comb points are formed at the tips of the transecting threads for better separating eyelashes. The threaded cosmetics applicator with feed channels is particularly well adapted for applying mid-weight thixotropic mascaras to eyelashes.

Abstract: A cosmetics container includes a bottle for holding liquid cosmetics and a cap having extending therefrom a rod and applicator brush for applying the cosmetics. The rod and applicator brush are inserted into the bottle through a resilient wiper comprising a tubular sleeve and an apertured wiper diaphragm. The wiper is mounted in the neck of the bottle by means of a wiper mounting ring, which receives and holds the wiper and snap-fits into the bottle neck. The size of the wiper mounting ring may be varied to fit into various size bottle necks without altering the wiper/applicator/cosmetics combination. The wiper and wiper mounting ring are assembled together prior to insertion into the bottle, so that they can be inspected prior to final assembly.

Abstract: The invention provides a novel method for evenly applying cosmetics, especially mascara, to an applicator brush and to the eyelashes. A cosmetic applicator formed with an applicator brush is removed from a container holding the cosmetic in a manner such that the applicator brush rubs against an applicator brush belonging to another applicator, thereby cleaning the brush to remove loose particles of the cosmetic and also causing cosmetic in the vicinity of the rubbing brushes to mix. This mixing action tends to thin ends of the cylindrical container and wherein the eyelash brushes of each of the cosmetic applicators are positioned along substantially the same longitudinal axis when the cap means of both cosmetic applicators are capped onto the container.

Abstract: The invention provides a dual cosmetic applicator and container for applying cosmetic, especially mascara, to the eyelashes in which a pair of eyelash brushes engage each other on the inside of a container holding a quantity of cosmetic. When an eyelash brush is removed from the container its bristles rub against the bristles of the other brush so as to mix the cosmetic which is applied to the brush. This mixing action tends to thin thixotropic cosmetic like mascara, making application of mascara to the eyelashes easier.
