Abstract

A wiper for wiping an associated cosmetic applicator, wherein the wiper has a retaining portion for securing the wiper on a cosmetic supply container, and also has at least two wiper arms, which are arranged on the container and subject the associated cosmetic applicator to wiping action. Each of the at least two wiper arms is arranged in an elastically movable manner on the retaining portion and has a shaft portion and a ring portion, which forms a wiper lip or a part thereof, wherein the extent of the ring portion in the circumferential direction is greater than the extent of the shaft portion in the circumferential direction.

Claims

1. A wiper for wiping off a cosmetics applicator associated with it, the wiper comprising:

a retaining portion that affixes the wiper to a cosmetics storage container; and

at least two wiper arms that are disposed thereon and exert a wiping action on the associated cosmetics applicator, wherein each of the at least two wiper arms is disposed on the retaining portion in an elastically movable manner and has a stem portion and a ring portion, which forms a wiper lip or a part thereof, wherein an extent of the ring portion in a circumferential direction is greater than an extent of the stem portion in the circumferential direction; and

wherein the ring portion, in each case on both sides of the stem portion associated with it, forms a ring arm completely curved in the circumferential direction which is connected to the central part of the ring portion only unilaterally and protrudes in the circumferential direction towards both sides over the stem portion, like a cantilevered beam attached only unilaterally.

2. The wiper according to claim 1, wherein a distal end of each stem portion is capable, where a transition into a respective ring portion takes place, of being displaced outwards in an elastically reversible manner in a radial direction, under forces arising as intended when a cosmetics applicator is wiped off, by more than 0.8 mm.

3. The wiper according to claim 1, wherein the stem portion is concavely curved on its inner face facing towards a longitudinal wiper axis and convexly curved on its outer face facing away from the longitudinal wiper axis, in each case viewed in the circumferential direction.

4. The wiper according to claim 1, wherein the ring portion of each of the at least two wiper arms, viewed in the circumferential direction, protrudes on both sides over a molded-on stem portion and thus forms ring arms which protrude on both sides over the stem portion.

5. The wiper according to claim 4, wherein together, the two ring arms constitute at least 35% of a length of the ring portion, viewed in the circumferential direction.

6. The wiper according to the claim 5, wherein the ring arms are so elastic that they are able to be resilient in a radially outward direction relative to the stem portion.

7. The wiper according to claim 1, wherein the ring portions of two diametrically opposing wiper arms form the entire wiper lip.

8. The wiper according to claim 1, wherein the ring portions form a circular ring in the circumferential direction that is substantially closed in itself.

9. The wiper according to claim 1, wherein a window is enclosed by two adjacent ring portions, the associated stem portions and the retaining portion.

10. The wiper according to claim 9, wherein a projection, which is connected on one side to the retaining portion and projects therefrom like a cantilever beam, protrudes into the window.

11. The wiper according to claim 10, wherein the projection ends, viewed in a direction of the longitudinal wiper axis, below the ring portions which, viewed in the circumferential direction, reach across the projection without touching the projection.

13. The wiper according to claim 1, wherein the wiper has at least three wiper arms whose stem portions all have different lengths in a direction of a longitudinal wiper axis, so that the ring portions of the wiper arms, viewed in the direction of the longitudinal wiper axis, are held at different distances from the retaining portion.

14. The wiper according to claim 13, wherein directly adjacent ring arms associated with different stem portions overlap in the direction of the longitudinal wiper axis without touching each other.

15. The wiper according to claim 14, wherein a gap, which increases in size in a vicinity of the retaining portion, where only the two stem portions are directly adjacent, remains free between every ring arm of a wiper arm and the stem portion of a directly adjacent longer wiper arm, and wherein a window remains free between two directly adjacent wiper arms, which is configured in a shape of a digit 6 and/or of a mirror-inverted digit 6.

16. The wiper according to claim 1, wherein the wiper is produced by injection molding or by a 3D printing method.

17. A cosmetics unit with a cosmetics storage container, an applicator, a closure cap and a wiper, which is mounted in a neck or a removal opening of the cosmetics storage container, for wiping off cosmetic mass from the wiper, the wiper being configured in accordance with claim 1.

12. A wiper for wiping off a cosmetics applicator associated with it, the viper comprising:

a retaining portion for fixing the wiper to a cosmetics storage container; and

at least two wiper arms that are disposed thereon and exert a wiping action on the associated cosmetics applicator, wherein each of the at least two wiper arms is disposed on the retaining portion in an elastically movable manner and has a stem portion and a ring portion, which forms a wiper lip or a part thereof, wherein an extent of the ring portion in a circumferential direction is greater than an extent of the stem portion in the circumferential direction;

wherein a window is enclosed by two adjacent ring portions, the associated stem portions, and the retaining portion;

wherein a projection, which is connected on one side to the retaining portion and projects therefrom like a cantilever beam, protrudes into the window; and

wherein the projection only covers a maximum of 55% of a surface area of the window.
