Abstract

A cosmetic stick for applying a liquid preparation to the skin of the user with a container into the opening of which a wiping means is inserted which comprises several lips of different configuration super-imposed at different levels, the upper lips thereof encompassing a shaft member of the applicator carrying an applicator pad, the lower lips surrounding said applicator pad made of soft plastic foam and having a smaller diameter than the applicator shaft.

Claims

1. A one-piece, integrally and simultaneously formed hollow wiper member for use in connection with an applicator assembly which includes a container having an open end and an applicator having an elongated shaft and an application member secured to one end of said shaft which is insertable into said one end of said container so as to remove a liquid or powdery preparation contained therein, comprising:

a hollow wiper housing having an internal surface defining an internal channel and at least two annular, asymmetrical, resilient, radially-deformable first wiper lips disposed successively in said channel of said wiper housing adjacent to said open end of said container and directed radially-inwardly from said surface of said wiper housing, each of said first wiper lips having a generally triangular cross section and having a radially inwardly and downwardly sloping upper surface and a radially inwardly and upwardly sloping lower surface converging into a wiping edge at an angle of about at least 90°

, said upper surface being longer than said lower surface, said edge having a diameter which is less than the diameter of said application shaft;

at least one second wiper lip disposed beneath and spaced apart from said first wiper lips in said housing, said second wiper lip having a smaller diameter than the application member so that when the applicator shaft and the member are withdrawn from said container, said second wiper lip makes wiping contact with the application member to portion the amount of liquid or powder removed from said container, and said first wiper lips become radially deformed and make wiping contact with said applicator shaft so as to completely clean and remove the powder or liquid adhering to the surface of said applicator shaft.

2. The wiper member according to claim 1, wherein the included angle between said upper and lower surfaces is 90°

.

3. The wiper member according to claim 1, wherein the included angle between said upper and lower surfaces of said first wiper lip is an obtuse angle.

4. The wiper member according to claim 1, wherein said wiper member has an upper end portion and a lower end portion, each of which has a generally hollow conical configuration and wherein said lower end portion forms said second wiper lip and tapers downwardly to a tip, said lower end portion having an axial slip formed therein which subdivides said lower end portion into two semiconically-shaped wiper lips which are disposed to enclose and make wiping contact with said application member of said applicator.

5. The wiper member according to claim 1, wherein said application member has a generally cylindrical configuration and wherein said wiper member has a lower hollow downwardly-tapered, frustoconical end portion forming said second wiper lip, the outer open end of which has a diameter which is smaller than the outer diameter of the application member of said applicator.

6. The wiper member according to claim 5, including a resilient disc mounted on said wiper device and closing said outer open end of said lower end portion, said disc having at least one diametrical slit formed therein to form a plurality of sector-shaped wiper lips.

7. The wiper member according to claim 1, wherein said hollow wiper member has a generally cylindrical outer surface which engages the inner wall of said container adjacent to said open end thereof.

8. The wiper member according to claim 7, wherein said outer cylindrical surface of said hollow wiper member has a circumferentially-extending annular recess formed therein which serves to promote the flexibility of said wiper lips by providing a more resilient support therefor.

9. An applicator device for applying to a surface a liquid or powdery substance from a container having an open end, comprising:

an applicator having an elongated shaft and an application member secured to one end of said shaft which is insertable into said open end of said container so as to remove a liquid or powdery preparation contained therein;

a one-piece, integrally and simultaneously formed hollow wiper housing mounted within said container adjacent to said open end thereof and having an internal surface defining a generally cylindrical internal channel and at least two resilient, annular, asymmetrical, radially deformable, first wiper lips which are successively disposed in said channel of said wiper housing adjacent to said open end of said container and which are directed radially-inwardly from said internal surface of said wiper housing, each of said first wiper lips having a generally triangular cross section and having, relative to said channel and said open end of said container, respectively, a radially-inwardly and downwardly-sloping, upper surface and a radially-inwardly and upwardly-sloping lower surface converging into a wiping edge at an angle of about at least 90°

, said upper surface being longer than said lower surface and said edge having a diameter which is less than the diameter of said application shaft; and

at least one second wiper lip disposed beneath and spaced apart from said first wiper lips in said housing, said second wiper lip having a smaller diameter than the application member so that when the applicator shaft and the member are withdrawn from said container, said second wiper lip makes wiping contact with the application member to portion the amount of liquid or powder removed from said container, and said first wiper lips become radially deformed and make wiping contact with said applicator shaft so as to completely clean and remove the powder or liquid adhering to the surface of said applicator shaft.

10. The applicator device according to claim 9, wherein the included angle between said upper and lower surfaces is 90°

.

11. The applicator device according to claim 9, wherein the included angle between said upper and lower surfaces of said first wiper lip is an obtuse angle.

12. The applicator device according to claim 9, wherein said wiper member has an upper end portion and a lower end portion each of which has a generally hollow conical configuration and wherein said lower end portion tapers downwardly to a tip, said lower end portion forms said second wiper lip and having an axial slit formed therein which subdivides said lower end portion into two semiconically-shaped wiper lips which are disposed to enclose and make wiping contact with said application member of said applicator.

13. The applicator device according to claim 9, wherein said application member has a generally cylindrical configuration and wherein said wiper member has a lower hollow downwardly-tapered, frustoconical end portion forming said second wiper lip, the outer open end of which has a diameter which is smaller than the outer diameter of the application member of said applicator.

14. The applicator device according to claim 13, including a resilient disc mounted on said wiper device and closing said outer open end of said lower end portion, said disc having at least one diametrical slit formed therein to form a plurality of sector-shaped wiper lips.

15. The applicator device according to claim 9, wherein said hollow wiper member has a generally cylindrical outer surface which engages the inner wall of said container adjacent to said open end thereof.

16. The applicator device according to claim 15, wherein said outer cylindrical surface of said hollow wiper member has a circumferentially-extending annular recess formed therein which serves to promote the flexibility of said wiper lips by providing a more resilient support therefor.
