Abstract
Abstract A cosmetic applicator including a normally liquid cosmetic containing reservoir and a self-contained brush. The open end of the reservoir is closed by a centrally apertured annular resilient diaphragm which provides means for sealing the reservoir against leakage and for wiping excess cosmetic from the bristles of the brush when the latter is being removed from the reservoir. The brush includes a two-part shaft with a peripheral depression defined intermediate the two parts and which projects through the diaphragm when the applicator is not in use. The depression is dimensioned such as to permit the diaphragm to maintain an unstressed condition as opposed to its stressed conditions caused during insertion and removal of the brush into and from the reservoir.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
121 words
A cosmetic applicator device comprising: a reservoir body open at one end; a closure supported in the open end and including a flexible wall arranged transversely of said body open end, said wall defining an aperture therein permitting access into said body; and brush means insertable through said aperture into said body, said brush means comprising an elongated assembly having a brush at one end thereof, said assembly having a fixed elongated outer surface with a portion of reduced diametEr therein arranged to fit snugly within said aperture with a liquid-tight fit and constituting a zone of minimum stress for said wall to maintain said wall in a sealing but generally unflexed condition when said assembly is housed in said body.
Claim 2
Dependent Claim
121 words
A cosmetic applicator device comprising: a reservoir body open at one end; a closure supported in the open end and including a flexible wall arranged transversely of said body open end, said wall defining an aperture therein permitting access into said body; and brush means insertable through said aperture into said body, said brush means comprising an elongated assembly having a brush at one end thereof, said assembly having a fixed elongated outer surface with a portion of reduced diametEr therein arranged to fit snugly within said aperture with a liquid-tight fit and constituting a zone of minimum stress for said wall to maintain said wall in a sealing but generally unflexed condition when said assembly is housed in said body.
Claim 3
Dependent Claim
82 words
A device as defined in claim 1, wherein a plug is mounted in said open end of said body for support of said closure, said plug having an end portion normally abutting said flexible wall of said closure, and said end portion of said plug abutting said flexible wall forming a backing against which said flexible wall is pressed in removal of said assembly from said body to establish by said flexible wall a wiper movable over said assembly and said brush.
Claim 4
Dependent Claim
39 words
A device as defined in claim 2, wherein said closure is generally cup-shaped in form and includes an annular wall mounted on said end portion of said plug and retained against the inner peripheral wall of said reservoir body.
Claim 5
Dependent Claim
43 words
A device as defined in claim 2, wherein said plug includes a tapered bore communicating with said aperture, and wherein said plug is threaded for mounting of a detachable cap in connection therewith, said cap supporting said assembly at the other end thereof.
Claim 6
Dependent Claim
41 words

Claim 7
Dependent Claim
47 words
A device as defined in claim 1, wherein said assembly comprises an outer tubular portion and an inner rod-shaped portion including an outer end received in said tubular portion, and wherein said portion of reduced diameter is defined in said rod-shaped portion directly adjacent said tubular portion.
Claim 8
Dependent Claim
43 words
A device as defined in claim 6, wherein said outer end of said rod-shaped portion includes a plurality of sharp-edged ribs anchored in the inner peripheral surface of said tubular portion to secure said outer end against inadvertent removal from said tubular portion.
Claim 9
Dependent Claim
31 words
A device as defined in claim 6, wherein said tubular portion includes an outer cylindrical surface and a tapered inner end joining said cylindrical surface and said portion of reduced diameter.
Claim 10
Dependent Claim
28 words
A device as defined in claim 8, wherein said tubular portion includes a tapered outer end terminating in a ferrule for fixing said brush in said tubular portion.
