International Classification:

A45D 33/00
B65D 69/00

US Classification:

132294, 132300, 206581

Abstract:

A dual dispensing mode cosmetic compact for use with a cosmetic powder puff, cosmetic applicator sponge, or cosmetic brush, has a base member with an annular lip, a well to hold a cake of cosmetic material, and a closure lid receivable onto the base member. A scraper member located adjacent the well is engageable with the upper surface of the cosmetic cake. Finger-engageable structures adjacent to the well are turnable thereon, and there is a driving connection between the finger-engageable structures and the scraper member, which effects corresponding turning movement of the latter during turning of the finger-engageable structures. In one mode, the scraper member shaves off limited quantities of the upper surface of the cosmetic cake to produce controlled amounts of dust-like cosmetic powder particulates therefrom. In another mode, the scraper member is shifted by the user, to a second position remote from and outside of the annular lip. This second position fully exposes the upper surface of the cosmetic cake and enables direct access to the cake surface by a cosmetic powder puff, cosmetic applicator sponge, or cosmetic brush.

International Classification:

A47L 13/26

US Classification:

401 37, 401 25, 401263, 401266

Abstract:

A cosmetic stick applicator for treating the lips of a person. The applicator has an elongate, tubular body with an inner chamber for storing a chemical formulation or substance such as an exfoliant, to be applied to the lips. One end of the body has an external, oblique, lip-engageable abrasive applicator surface containing a product-dispensing orifice through which the substance can be ejected. Such ejection is accomplished by means of a finger-engageable wheel that is turned to forcibly discharge the substance through the orifices and onto the applicator surface. Thereafter this surface which now contains the discharged substance, is rubbed against the lips and thus effects a scrubbing thereof, which brings about gentle and controlled exfoliation of accumulated dead skin cells. Following this, excess dead cell material can be wiped off with a tissue or pad.
