Abstract

A liquid nail polish applicator having a bottle containing a supply of nail polish and a brush applicator on the open end of the bottle. The brush is supplied with nail polish liquid internally through the brush bottle upon the removal of the center seal from the open end of the bottle and upon inverting the bottle.

Claims

1. A brush fluid applicator assembly for nail polish or the like comprising a hollow body receptacle adapted to contain fluid and having an open end, a cap for said open end having at least one port therein, a plug for said open end having a projecting sealing post, a brush holder provided with a passageway for said fluid, a brush anchor for functionally securing a plurality of brush lengths in combination with said brush holder, said brush anchor being provided with a channel, whereby when said cap and brush holder are turned in one direction the sealing post blocks said passageway to prevent the movement of fluid therethrough, and when said cap and brush holder is turned in the opposite direction the sealing post is removed from said passageway thereby permitting fluid to flow by gravity or pressure from said fluid storage compartment through said port in said cap, said passageway and channel and internally and substantially centrally through the bristles of said brush lengths.

2. A brush fluid applicator assembly as claimed in claim 1 further comprising an overcap for said applicator provided with an inner cap having a solvent permeable wall.

3. A brush fluid applicator as claimed in claim 1 wherein said brush holder is provided with an internal groove, and said brush anchor has a plurality of legs for holding portions of said brush lengths in said groove while the ends of said brush lengths protrude freely from said brush holder.

4. A brush fluid applicator as claimed in claim 3 wherein said brush anchor is provided with a hollow center post surrounded by said legs circumferentially, and said brush lengths being positioned and held between said legs and center post.

5. A brush fluid applicator as claimed in claim 1 wherein said cap and brush holder assembly is screw-connected to said hollow body receptacle and the end thereof remote from said receptacle is provided with a recess for securely holding said brush holder.

8. A brush fluid applicator as claimed in claim 3 further comprising a space formed between said inner cap and overcap and having a solvent therein, and wherein said solvent permeable wall in said inner cap is provided with at least one hole for transfer of said solvent from said space to the free ends of said brush lengths.

6. A brush assembly for a nail polish bottle or the like including a removable cap comprising a brush guide provided with a central passageway and an annular groove surrounding at least a part of said passageway said brush guide being mounted in said cap, a brush anchor provided with a plurality of legs, and a central passageway through, and a plurality of brush lengths having a median portion thereof entrapped between said legs, and secured in said brush holder upon insertion of said brush anchor in said passageway with said legs and said median portions of the brush lengths being located in said annular groove, while the free ends of said brush lengths project out of said brush guide.

7. A brush assembly for nail polish or the like as claimed in claim 9 wherein said brush guide and brush anchor are both fabricated of a plastic material.
