Abstract

Disclosed is an improved eyeliner applicator having a quantity of eyeliner-soaked material packed into the hollow space of its cap, whereby its felt tip is inserted into the eyeliner-soaked material when its cap is placed on its shank, thereby maintaining its tip wet with the eyeliner liquid. This arrangement permits automatic removal of dust from the tip surface every time the tip is inserted into the eyeliner-soaked material, thus maintaining the tip surface free of dust to assure a smooth supply of the eyeliner to the tip surface.

Claims

1. An eyeliner applicator comprising:

a tip member of a material which permits permeation of an eyeliner liquid;

a holder to hold said tip member;

a shank attached to a rear end of said holder; and

a hollow cap containing a quantity of eyeliner liquid and having an elastic plug membrane inside said hollow cap to prevent outflow of said eyeliner liquid from the hollow cap, said plug membrane having a bottom membrane with an inner wall which forms a trigonal pyramid space having ridgelines and said bottom membrane having a nearly triangular small mouth which is deformable at a bottom end of said inner wall to allow said tip member to enter the hollow space of said cap, therein maintaining said tip member wet with said eyeliner liquid, said triangular small mouth allowing air to flow into and out of said cap along a gap formed at each ridgeline of said trigonal pyramid space when said tip is inserted in said plug member preventing negative pressure in said cap.

2. A eyeliner applicator according to claim 1 wherein said holder and said hollow cap are threadedly fitted.

3. An eyeliner applicator according to claim 2 wherein said shank is hollow, said holder having a hollow rear end which is opened in the hollow shank and an air passage hole which communicates with the hollow shank.

4. An eyeliner applicator according to claim 3 further comprising an O-ring provided on the holder for sealing a gap between the holder and the cap.

5. An eyeliner applicator according to claim 1 wherein said hollow cap further comprises a collar ring located at one end of the plug membrane to prevent deformation of said elastic plug membrane.

6. An eyeliner applicator according to claim 1 wherein said triangular small mouth being deformed to a round shape when said tip member is inserted therein.

7. An eyeliner applicator according to claim 1 wherein said triangular small mouth presses on said tip member when said tip member is withdrawn from said plug membrane, wherein excessive eyeliner liquid infiltrated in said tip member is wiped by said mouth.

8. An eyeliner applicator according to claim 1 wherein said triangular small mouth having a size, when said tip member is not inserted therein, which prevents said eyeliner liquid from flowing out.

9. An eyeliner applicator according to claim 8 wherein said size of said triangular small mouth is 1 to 2 mm.

10. An eyeliner applicator comprising:

a tip member of a material which permits permeation of an eyeliner liquid;

a holder to hold said tip member;

a shank attached to a rear end of said holder; and

a hollow cap containing a quantity of eyeliner liquid and having an elastic plug membrane to prevent outflow of said eyeliner liquid from the hollow cap, said plug membrane having a cylindrical wall fixedly fitted within the hollow cap and having a bottom membrane with an inner wall which forms a trigonal pyramid space having ridgelines and said bottom membrane having a nearly triangular small mouth at a bottom end of said inner wall to allow said tip member to enter the hollow space of said cap, therein maintaining said tip member wet with said eyeliner liquid, said triangular small mouth allowing air to flow into and out of said cap along a gap formed at each ridgeline of said trigonal pyramid space when said tip is inserted in said plug member preventing negative pressure in said cap.

11. An eyeliner applicator according to claim 10 wherein said triangular small mouth being deformed to a round shape when said tip member is inserted therein.

12. An eyeliner applicator according to claim 10 wherein said triangular small mouth presses on said tip member when said tip member is withdrawn from said plug membrane, wherein excessive eyeliner liquid infiltrated in said tip member is wiped by said mouth.

13. An eyeliner applicator according to claim 10 wherein said triangular small mouth having a size, when said tip member is not inserted therein, which prevents said eyeliner liquid from flowing out.

14. An eyeliner applicator according to claim 13 wherein said size of said triangular small mouth is 1 to 2 mm.
