Abstract
Abstract The embodiment shown in the drawing comprises a central cylindrical member which at each end is formed with internally threaded sleeves meeting a solid area from which integrally project oppositely directed rods, one of the rods carrying, in the said embodiment, an eyeliner narrow brush, and the second rod carrying a spiral mascara applicator. The assembly includes two cover members, each of which is a reservoir for the appropriate cosmetic, and each cover member serves as a handle when the opposite cover is removed for use of the particular applicator exposed when said cover is removed. The reservoir in each cover lies toward its closed end, forwardly of which is an internal cover wall formed with an aperture for passage of the rod and applicator, but the wall closely having slidable contact for the latter and serving both as a complementary closure for the reservoir and as a wiper for the rod and applicator. The construction provides a double cosmetic dispensing applicator in small space, and one which can be safely carried, a fully operative size being, for example, less than the diameter of the usual lipstick and only about one third longer.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
250 words
A cosmetic device for selectively applying either one of two cosmetic fluids, said device comprising in combination: a generally tubular base member including a crosswise partition wall intermediate its length; a pair of applicator members each including a rod and an applicator secured to one end of the respective rod, the other ends of the rods being integral with the opposite sides of said partition wall coaxially with the base member; and a pair of generally tubular cover members closed at one end, the open ends of said cover members being engageable with the opposite ends of the base member for releasable attachment therein, each of said cover members including a crosswise partition wall having a central opening, the spaces between said crosswise partition walls and the closed ends of the cover members each constituting a reservoir for cosmetic fluid to be applied, the length of each rod and the position of the apertured partition wall in each cover member being so correlated that upon attachment of the respective cover member to the base member the applicator and the rod end mounting the same protrude through the respective wall aperture into the reservoir in the cover member, and the peripheral outline of each aperture and the cross-sectional area of the respective rod being so correlated that excess cosmetic fluid adhering to the respective applicator and rod is wiped off upon detachment of the cover member from the base member and thus withdrawal of the respective applicator from the respective reservoir.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
48 words
The cosmetic device according to claim 1 wherein a liner is fitted in the open end of each cover member protruding therefrom, each of the apertured partition walls in the cover members being secured to the inner end of the respective liner thereby forming an end wall therefor.
Claim 4
Dependent Claim
43 words
The cosmetic device according to claim 2 wherein the inner wall of the base member ends and the outer wall of the protruding liner ends are threaded for threaded engagement of said walls thereby releasably attaching the cover members on the base member.
Claim 5
Dependent Claim
43 words
The cosmetic device according to claim 1 wherein a sleeve is fitted into each end of the base member, said sleeve being closed at its outer end by apertured end wall, the respective rod extending through said end wall thereby steadying the rod.
