## Abstract

This invention relates to manicuring devices in general and more specifically to a receptacle for nail polish remover, having a brush member disposed within the receptacle in a unique manner, and a novel resilient closure member which prevents evaporation of the contents of the receptacle and provides an abrasive surface for a finger entering the receptacle, and a wiping surface for a finger being withdrawn from the receptacle.

## Claims

### Claim 1

An improved container for liquid nail polish remover comprising:
a generally rectangular receptacle having a large circular opening formed by a raised threaded neck portion,
a brush element having support means disposed in the interior of said receptacle,
a resilient apertured primary closure means secured to said raised neck portion; wherein,
the primary closure comprises a resilient diaphragm having an elongated slit disposed at its midpoint, and a beaded periphery which is dimensioned to be received within a recess in said raised neck portion; and the resilient diaphragm is further provided with abrasive particles disposed on its exterior surface adjacent the elongated slit.

### Claim 2 (depends on 1)

An improved container as in claim 1, further comprising:
a secondary closure in the form of a threaded cap which cooperates with said threaded neck portion to seal the container.

### Claim 3 (depends on 2)

An improved container as in claim 2: wherein,
the recess in said raised neck portion is formed on the exterior surface.

### Claim 4 (depends on 2)

An improved container as in claim 2; wherein,
the recess in said raised neck portion is formed on the interior surface.

### Claim 5 (depends on 3)

An improved container as in claim 3; wherein,
the secondary closure compresses a portion of the resilient primary closure against the threaded neck portion to provide a vapor and liquid tight seal.

### Claim 6 (depends on 5)

An improved container as in claim 5; wherein,
said brush element comprises a generally U-shaped substrate supported by wire legs and having a plurality of bristles disposed thereon.

### Claim 7 (depends on 6)

An improved container as in claim 6; wherein,
the receptacle opening and interior are dimensioned to receive the brush element within the interior, with only the bristles on the brush element being deformed, when the brush element is inserted into the receptacle.

### Claim 8 (depends on 2)

An improved container as in claim 2; wherein, said primary closure forms a virtually spill-proof barrier for a liquid within the container.
