Abstract

A mascara applicator includes a receptacle, a pre-stripper and an end stripper, wherein the pre-stripper is associated with a brush and the end stripper is associated with a shaft. The shaft in turn is fixed to the brush and a screw cap. In the screwed-in position, the shaft is simultaneously grasped by segments of the pre-stripper and by stripper lips of the end stripper. Also, the pre-stripper has radially elastic segments which can pivot around a pivoting edge and which have slits which can be changed in width whereby radial forces can be transmitted to the segments by means of a spring loop.

Claims

1. A device for applying paste materials having a receptacle, a pre-stripper, and an end stripper, wherein the pre-stripper is slidably engaged with a brush, and the end stripper is slidably engaged with a shaft, wherein the shaft is fixed to the brush and the screw cap, wherein in a screwed-in position, the shaft (10) is simultaneously engaged by segments (6) of the pre-stripper (5) and by stripper lips of the end stripper (16), wherein the pre-stripper (5) is comprised of the radially elastic segments (6), which pivot around a pivoting edge (8) and which in relation to one another, constitute slits (7) which can be changed in width, and that radial forces are transmitted to the segments (6) by means of a spring loop.

2. The device according to claim 1, wherein a pivot angle of the segments (6) is determined by the gradual laying of a stripper edge (9) against the shaft (10), as well as against a twisted rod (11) and by the reciprocal touching of the stripper edges (9) against one another after withdrawal of the brush (13).

3. The device according to claim 2, wherein upon contact of the stripper edges (9) against the twisted rod (11), the segments (6) constitute slits (7), which are reduced in width and represent an opening for the material (2).

4. The device according to claim 1, wherein the material (2) can be applied to the brush (13) in longitudinal stripes by means of the slits (7).

5. The device according to claims 4, wherein after withdrawal of the brush (13) along with the twisted rod (11), there is a slit width of the value zero at the stripper edges (9).

6. The device according to claim 1, wherein the stripper lips of the end stripper (16) constitute a damming edge for the longitudinal stripes of material (2) disposed on the brush (13).

7. The device according to claim 1, wherein the spring loop is embodied as a flat coil spring with up to a maximum number of 1.5 turns and that spring ends (15 &

15'"'"') of said spring loop are tangentially extended away from a circle of the spring loop.

8. The device according to claim 7, wherein the spring loop is a toroidal sealing ring of an elastic rubber material.

9. The device according to claim 1, wherein the length (a) of the external thread (3) is longer than the projection (b) of the shaft (10).

10. The device according to claim 1, wherein the working parts comprised of the pre-stripper (5) with segments (6), the spring loop (14), and the end stripper (16) can be formed as a separate structural unit.

11. The device according to claim 10, wherein the separate structural unit can be used in commercially available products.

12. The device according to claim 1 wherein after withdrawal of the brush (13) along with the twisted rod (11), there is a slit width of the value zero at the stripper edges (9).

13. The device according to claim 2 wherein after withdrawal of the brush (13) along with the twisted rod (11), there is a slit width of the value zero at the stripper edges (9).

14. The device according to claim 3 wherein after withdrawal of the brush (13) along with the twisted rod (11), there is a slit width of the value zero at the stripper edges (9).
