Abstract

A liquid-cosmetic applicator capable of avoiding pumping phenomenon without lowering the scraping function of its wiper is provided. The liquid-cosmetic applicator has a wiper (15) formed on the inside of an opening (12) of a liquid-cosmetic container (10) for scraping off the liquid cosmetic (13) that adheres to the stem (36) of a stemmed brush (30). The wiper has an axially offset region occupying a certain peripheral domain of the wiper and an axially non-offset region occupying another peripheral domain including another scraping section. The offset region and non-offset region include scraping sections (17A, 17B), respectively, that overlap in the axial direction, leaving a gap formed between, and along the peripheries of, the overlapping scraping sections (17A, 17B). A minute gap (air passage) (19) communicating with the spaces (S1, S2) above and below the wiper (15), respectively, is formed along the outer surface of the stem (36) of the stemmed brush (30) in tight contact with the axially overlapping region of the scrapping section, allowing the air in the container to freely escape from the container. Hence, no pumping phenomenon will occur. The scraping sections (17A, 17B) are continuous in the their peripheral direction, thereby leaving no cosmetic on the stem of the brush.

Claims

1. A liquid-cosmetic applicator having a wiper formed on the inside of an opening of a liquid-cosmetic container for scraping off the liquid cosmetic that adheres to the stem of a stemmed brush, wherein:

said wiper has at least one axially offset region occupying a peripheral domain of said wiper and including a scraping section;

said offset region and a non-offset region share a joint section extending in the peripheral direction of said wiper; and

said scraping section of said offset region and the scraping section of a non-offset region in said joint section overlap in said axial direction such that a gap is formed between, and along the inner peripheral surfaces of, said overlapping scraping sections, said gap extending in the axial direction.

2. The liquid-cosmetic applicator according to claim 1, wherein

said wiper has a cylindrical shape tapered in the direction from the opening to the inside of said container;

said wiper has a multiplicity of axially offset and non-offset regions distributed at substantially equal angular intervals about the axis of said wiper, each region occupying a peripheral domain of said wiper and including a respective scraping section, the scraping sections in said multiple regions overlapping in the axial direction of said wiper.

3. A liquid-cosmetic applicator having a wiper formed on the inside of the opening of a liquid-cosmetic container for scraping off the cosmetic that adheres to the stem of a stemmed brush, wherein:

said wiper has a spiral scraping section that partly overlaps itself in the axial direction thereof, thereby resulting in overlapping portions to form a spiral gap between, and along the inner peripheral surfaces of, said axially overlapping portions.
