ABSTRACT:
A cosmetic dispenser containing an elevator cup carrying a solid cosmetic product, a sleeve in which the cup is axially advanceable and retractable, and an operating shell turnably mounted on the sleeve. The sleeve has either two or else three equispaced longitudinal slots and the elevator cup has two or else three equispaced lugs passing through and projecting from the slots of the sleeve. The operating shell has two or else three internal spiral tracks respectively engaged by the lugs of the cup to propel the latter in response to relative turning between the shell and sleeve. The arrangement is such that the cup is advanced and retracted by balanced forces applied at uniformly spaced circumferential locations about the cup. The cup has resilient fingers that are forced inward by the sleeve, forming a collet which firmly holds the lipstick pomade. The sleeve has a lateral spur track which holds the cup captive in the sleeve. Reduced tendency for undesirable tilting of the cosmetic stick product is thus realizeable.
