Abstract

An epilator includes an epilation head and a massage roller arranged next to the epilation head. The massage roller is rotatable about a longitudinal axis and includes pairs of elementary massaging members positioned in a V-shape relative to each other. Each elementary massaging member may be a round, elliptical, or polygonal disc.

First claim

The invention claimed is:

1. An epilator comprising:
an epilation head; and
a massage roller arranged next to the epilation head,
wherein the massage roller is rotatable about a longitudinal axis and comprises pairs of first and second elementary massaging members, each of the first and second elementary massaging members being a disc having a normal axis;
wherein, for each pair of the first and second elementary massaging members, the normal axis of the first elementary massage member is at a first angle with the longitudinal axis, and the normal axis of the second elementary massage member is at a second angle with the longitudinal axis, and an edge of the first elementary massage member is joined to an edge of the second elementary massage member, such that the first and second elementary massaging members from a V-shape relative to each other when viewed from a direction perpendicular to the longitudinal axis and an angle of the V-shape being determined by the first and second angles.

2. The epilator as claimed in claim 1 ,
wherein the elementary massaging members are arranged in a row along the longitudinal axis.

3. The epilator as claimed in claim 1 , wherein each elementary massaging member is a round, elliptical, or polygonal disc.

4. The epilator as claimed in claim 3 , wherein a normal axis of each disc and the longitudinal axis enclose an angle between 5 degrees and 85 degrees.

5. The epilator as claimed in claim 1 , wherein the pairs are arranged in positions which are mutually rotated about the longitudinal axis.

6. The epilator as claimed in claim 1 , wherein a skin contact surface of each elementary massaging member is smooth.

7. The epilator as claimed in claim 1 , wherein each elementary massaging member has an instantaneous skin contact surface and an axial extension, wherein the axial extension varies as the roller is rolled across a skin.

8. The epilator as claimed in claim 7 , wherein the instantaneous skin contact surface is non-vanishing.

9. The epilator as claimed in claim 1 , wherein a projection of the massage roller on a plane containing the longitudinal axis is wave-shaped or zig-zag-shaped.

10. The epilator as claimed in claim 1 , wherein the massage roller is an injection moulded piece or comprises a rigid inner structure covered by an elastic material.

11. The epilator as claimed in claim 1 , wherein the epilator comprises a reversibly detachable cap surrounding a portion of the epilation head and wherein the massage roller is mounted to the cap.

12. The epilator as claimed in claim 1 , wherein the massage roller is spring-biased toward a skin.

13. The epilator as claimed in claim 1 , wherein the epilator comprises a driving mechanism for driving the massage roller.

14. The epilator as claimed in claim 1 , wherein the massage roller is reversibly detachable from the epilator.

15. An epilator comprising:
an epilation head; and
a massage roller arranged next to the epilation head and being rotatable about a longitudinal axis,
wherein a projection of the massage roller on a plane perpendicular to the longitudinal axis is a superposition of two ellipses rotated relative to each other by 90 degrees.

16. The epilator of claim 15 , wherein the massage roller comprises massaging members, each massaging member contacting a skin twice during one revolution of the massage roller.
