Abstract

Abstract A cosmetics applicator brush includes a ribbed flexer at the distal portion of the rod. Bristles extend outwardly from the flexer, some of the bristles being supported on the ribs and some being supported in grooves between the ribs. When the brush is loaded with cosmetics and drawn through a wiper diaphragm of the cosmetics container, the bristles on the larger diameter ribs are wiped relatively clean and the bristles in the grooves are subjected to less or no wiping action and carry a substantial amount of cosmetics for application. The relatively clean bristles extending from the ribs provide good combing action of the applied cosmetics.

Claims Analysis

Total Claims: 21
Claim 1
Independent Claim 55 words
A cosmetics applicator brush comprising: (A) a rod; (B) a flexer positioned at the end of said rod, the flexer having outwardly extending rib portions defining grooved portions therebetween; and (C) bristles secured to the exterior of said ribbed flexer and extending outwardly therefrom, said bristles deployed on both of said rib and grooved portions.
Claim 2
Dependent Claim 55 words
A cosmetics applicator brush comprising: (A) a rod; (B) a flexer positioned at the end of said rod, the flexer having outwardly extending rib portions defining grooved portions therebetween; and (C) bristles secured to the exterior of said ribbed flexer and extending outwardly therefrom, said bristles deployed on both of said rib and grooved portions.
Claim 3
Dependent Claim 20 words
A cosmetics applicator brush as defined in claim 1 wherein said flexer includes a tip at the distal end thereof.
Claim 4
Dependent Claim 30 words
A cosmetics applicator brush as defined in claim 1 wherein said flexer and rod are fabricated in separate pieces and said flexer is mounted to one end of said rod.
Claim 5
Dependent Claim 27 words
A cosmetics applicator brush as defined in claim 3 wherein said flexer has a stem portion received in an opening formed in the end of said rod.
Claim 6
Dependent Claim 22 words
A cosmetics applicator brush as defined in claim 3 wherein said rod is fabricated of a more rigid material than said flexer.
Claim 7
Dependent Claim 39 words
A cosmetics applicator brush as defined in claim 1 wherein the ribbed portion of said flexer comprises a plurality of annular ribs and the grooved portion of said flexer comprises a plurality of annular grooves defined between the ribs.
Claim 8
Dependent Claim 25 words
A cosmetics applicator brush as defined in claim 1 wherein the bristles are oriented substantially perpendicularly to the flexer surface to which they are attached.
Claim 9
Dependent Claim 43 words
A cosmetics applicator brush as defined in claim 7 wherein the bristles are all of approximately the same length, whereby those bristles secured to the ribbed portions of the flexer extend outwardly beyond those bristles secured in the grooved portion of the flexer.
Claim 10
Dependent Claim 39 words
A cosmetics applicator brush as defined in claim 7 wherein the ribbed portion of the flexer comprises a plurality of annular ribs and the grooved portion of the flexer comprises a plurality of annular grooves defined between the ribs.
Claim 11
Dependent Claim 41 words
A cosmetics applicator brush as defined in claim 9 wherein the bristles are all of approximately the same length, whereby those bristles secured to the ribs of the flexer extend outwardly beyond those bristles secured in the grooves of the flexer.
Claim 12
Dependent Claim 26 words
A cosmetics applicator brush as defined in claim 10 wherein the annular ribs have outer cylindrical surfaces, whereby the ribs support a substantial number of bristles.
Claim 13
Dependent Claim 73 words
A cosmetics applicator brush as defined in claim 9 wherein the plurality of annular ribs comprises a plurality of annular discs spaced apart on a flexer core of smaller diameter than the ribs and aligned with the rod of the cosmetics applicator brush, each of the discs having their planes perpendicular to the shaft of the flexer and having an outer cylindrical surface for supporting some of the bristles attached to the flexer.
Claim 14
Dependent Claim 41 words
A cosmetics applicator brush as defined in claim 12 wherein the bristles are all of approximately the same length, whereby those bristles secured to the ribs of the flexer extend outwardly beyond those bristles secured in the grooves of the flexer.
Claim 15
Dependent Claim 20 words
A cosmetics applicator brush as defined in claim 13 wherein said flexer includes a tip at the distal end thereof.
Claim 16
Dependent Claim 32 words
A cosmetics applicator brush as defined in claim 9 wherein each of said ribs has concave curved diverging sidewalls which join with the sidewalls of adjacent ribs to define concave grooves therebetween.
Claim 17
Dependent Claim 41 words
A cosmetics applicator brush as defined in claim 15 wherein the bristles are all of approximately the same length, whereby those bristles secured to the ribs of the flexer extend outwardly beyond those bristles secured in the grooves of the flexer.
Claim 18
Dependent Claim 20 words
A cosmetics applicator brush as defined in claim 16 wherein said flexer includes a tip at the distal end thereof.
Claim 19
Dependent Claim 40 words
A cosmetics applicator brush as defined in claim 9 wherein the annular ribs have sidewalls which converge and join at the outside circumference of said ribs, the sidewalls of adjacent ribs converging together to define V-shaped grooves between said ribs.
Claim 20
Dependent Claim 41 words
A cosmetics applicator brush as defined in claim 18 wherein the bristles are all of approximately the same length, whereby those bristles secured to the ribs of the flexer extend outwardly beyond those bristles secured in the grooves of the flexer.
Claim 21
Dependent Claim 151 words
A cosmetics applicator brush as defined in claim 1 in combination with a cosmetics container having cosmetics therein, the cosmetics container defining an entry/exit passageway having a wiper diaphragm disposed thereacross, and including a cap to which the end of the rod opposite the flexer of the cosmetics applicator brush is secured, the wiper diaphragm having an aperture through which the flexer and attached bristles of the cosmetics applicator brush pass in entering and exiting the cosmetics container, the diameter of the aperture opening in the wiper diaphragm providing more vigorous wiping action on the bristles extending from the ribbed portion of the flexer than on the bristles in the grooved portions of the flexer, wherein the bristles in the grooved portions of the flexer carry substantial amounts of cosmetics for application and the bristles extending from the ribbed portions of the flexer are wiped relatively clean to provide combing action.
