Abstract

A liquid-cosmetic applicator is provided having a wiper formed on the inside of an elongated opening of a liquid-cosmetic container for scraping off the liquid cosmetic that adheres to the stem of a stemmed brush. The wiper includes at least two wiper domains that overlap along the longitudinal axis of said opening, each domain having a scraping section at one axial end, and a non-scraping section at an opposite end, the scraping sections being axially offset from one another and having sides that mutually engage along at least one interface. The interface provides a gap between said stem when said stem of said brush engages said scraping sections of said wiper domains that in turn defines an air passage that allows air to axially flow through said wiper as said stem is being wiped thereby eliminating unwanted suction forces when the applicator is withdrawn from the container.

Claims

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

at least two wiper domains that overlap along the longitudinal axis of said opening, each domain having a scraping section at one axial end, and a non-scraping section at an opposite end, said scraping sections being axially offset from one another and having sides that mutually engage along at least one interface,

wherein said interface defines a gap between said stem when said stem of said brush engages said scraping sections of said wiper domains that in turn defines an air passage that allows air to axially flow through said wiper as said stem is being wiped.

2. The liquid-cosmetic applicator of claim 1, wherein said non-scraping sections of said wiper domains terminate in edges, and said edges of said non-scraping sections are axially aligned with one another.

3. The liquid-cosmetic applicator of claim 1, Wherein said wiper includes only two wiper domains.

4. The liquid-cosmetic applicator of claim 1, wherein said interface between said side walls is axially aligned.

5. The liquid-cosmetic applicator of claim 1, wherein the axial length of one of said wiper domains is different from the axial length of the other wiper domain.

6. The liquid-cosmetic applicator of claim 1, wherein said wiper domains are frustro-conical, and said stem is substantially cylindrical.

7. The liquid-cosmetic applicator of claim 1, wherein the circumferential extent of said wiper domains is substantially equal.
