Abstract

A cosmetic unit, especially a mascara unit, comprises a storage container for a mascara liquid, a closing cap for placing onto the storage container, an applicator rod incorporating an applicator and extending away from the inside of the closing cap through an orifice, and a wiper means placed in the orifice of the container, wherein the wiper means extends sufficiently far from the edge of the orifice into the interior of the container so that the wiper orifice or the wiper lips of the wiper means, when the applicator is in the inserted condition, extend to the region of the proximal edge of the applicator.

Claims

1. A cosmetic unit, especially a mascara unit, comprising a storage container for a mascara liquid, a closing cap for placing onto the storage container, an applicator rod incorporating an applicator and extending away from the inside of the closing cap through an orifice, and a wiper means placed in the orifice of the container, wherein the wiper means (11) extends sufficiently far from the edge of the orifice (3) into the interior of the container (2) so that the wiper orifice (15) or the wiper lips (16) of the wiper means (11), when the applicator (10) is in the inserted condition, extend to the region of the proximal edge of the applicator (10) so that, in the inserted condition, the applicator rod (9) is located within the wiper means (11) and the applicator (10) is located outside the same, wherein the rod (9) has a considerably smaller diameter compared to the basic diameter of the applicator (10).

2. A cosmetic unit according to claim 1, wherein the wiper means (11) has an intrinsic stiffness such that it remains substantially rigid despite its distal extension when the applicator (10) is withdrawn.

3. A cosmetic unit according to claim 2, wherein the edge of the wiper orifice (15) or the wiper lips (16) of the wiper means (11) consist of a softer material than the main body (12).

4. A cosmetic unit according to claim 3, wherein the main body (12) of the wiper means (11) consists of harder synthetic material and the edge of the wiper means (15) or the wiper lips (16) consist of softer synthetic material and they are produced by means of co-extrusion.

5. A cosmetic unit according to claim 1, wherein the wiper means (11) has an elongated, frusto-conical basic shape.

6. A cosmetic unit according to claim 1, wherein the rod (9) has above the applicator (10) a contraction and the wiper lips (16) in the closed condition engage into this contraction.

7. A cosmetic unit according to claim 1, wherein the applicator (10) consists of synthetic material.

8. A cosmetic unit according to claim 1, wherein the wiper lips (16) incorporate at their inner end a bent region having a blunt, sharp or 90°

angle.

9. A cosmetic unit according to claim 1, wherein the wiper lips (16) have, at the wiper orifice (15) a radius of 0.2 to 5.0 mm.

10. A cosmetic unit according to claim 9, wherein the wiper lips (16) have, at the bent region, a radius of 0.2 to 5.0 mm on the outside and a radius of 0.2 to 7.0 mm on the inside.

11. A cosmetic unit according to claim 1, wherein a wiper lip (16) in the form of a torus having a radius of 0.2 to 10.0 mm and an axial length of 0.1 to 5.0 mm is injection molded integrally with the wiper means.

12. A cosmetic unit according to claim 4, wherein the wiper lips (16) are composed of rubber and produced by means of injection molding and vulcanizing.

13. A cosmetic unit according to claim 1, wherein the wiper means (11) has, in the region of the upper orifice (3), at least one locking channel for locking it into place on the inside container neck wall.

14. A cosmetic unit according to claim 1, wherein the outside diameter of the wiper means is slightly larger than the inside diameter of the container neck and the wiper means is accordingly securable on the container neck by means of a friction fit.
