Abstract

The present invention relates to an applicator brush ( 1 ) for applying a cosmetic, make-up or care product to human keratin materials, especially the eyebrows, comprising a handle ( 4 ) which extends along a longitudinal axis (X) and, at the distal end thereof, an applicator head ( 2 ) having distal ( 2 c ) and proximal ends, and carrying a tuft ( 3 ) of bristles ( 6 ), the free ends ( 6 a ) of which define an applicator surface ( 5 ) that is convex towards the outside, in which applicator the applicator head ( 2 ) extends along a longitudinal axis (Y) that is not parallel to the longitudinal axis (X) of the handle ( 4 ), and wherein the tuft ( 3 ) of bristles ( 6 ) is arranged such that the transverse dimension of the applicator surface ( 5 ) increases towards the distal end ( 2 c ) of the applicator head ( 2 ), passing through a maximum, before decreasing from the location at which the transverse dimension is maximum towards the distal end ( 2 c ), the maximum of the transverse dimension of the applicator surface ( 5 ) being closer to the proximal end of the applicator head ( 2 ) than to the distal end ( 2 c ) thereof.

First claim

The invention claimed is:

1. An applicator brush for applying a cosmetic, make-up or care product to the eyebrows, comprising a handle which extends along a longitudinal axis and, at a distal end thereof, an applicator head having distal and proximal ends, and carrying a tuft of bristles, free ends of which define an applicator surface that is convex towards an outside,
in which applicator the applicator head extends along a longitudinal axis that is not parallel to the longitudinal axis of the handle,
wherein the tuft of bristles is arranged such that a transverse dimension of the applicator surface increases towards the distal end of the applicator head, passing through a maximum, before decreasing from a location at which the transverse dimension is maximum towards the distal end, the maximum of the transverse dimension of the applicator surface being closer to the proximal end of the applicator head than to the distal end thereof,
wherein a ratio between a largest transverse dimension of the applicator head and a length of the applicator head is between 0.4 and 0.5, and
wherein the maximum of the transverse dimension of the applicator surface is located halfway along a first half of the applicator surface, starting from a part which connects the applicator head to the handle.

2. The applicator brush as claimed in claim 1 , wherein the tuft of bristles is arranged on an opposite side to a depression of a bend formed by the applicator head and the handle when the brush is viewed from the side.

3. The applicator brush as claimed in claim 1 , wherein the axis along which the applicator head extends forms, with the longitudinal axis of the handle, an angle of between 15° and 45°.

4. The brush as claimed in claim 1 , wherein the transverse dimension of the applicator head increases towards the distal end thereof, passing through a maximum, before decreasing from the location at which the transverse dimension is maximum towards the distal end.

5. The brush as claimed claim 1 , wherein the tuft of bristles comprises bristles of different lengths arranged such that the applicator surface is convex towards the outside.

6. The applicator brush as claimed in claim 1 , wherein the applicator surface is convex about an axis perpendicular to the longitudinal axis of the applicator head.

7. The applicator brush as claimed in claim 1 , wherein the applicator surface is convex about the longitudinal axis of the applicator head.

8. The applicator brush as claimed in claim 1 , wherein the largest transverse dimension of the applicator surface is between 2.5 mm and 6 mm, and the length thereof, measured along the longitudinal axis of the applicator head, is between 7 mm and 12 mm.

9. The brush as claimed in claim 1 , wherein the thickness of the handle tapers in the direction of the part thereof which is connected to the applicator head.

10. The brush as claimed in claim 1 , wherein the transverse dimension of the handle decreases in the direction of the part thereof which is connected to the applicator head, the ratio between the minimum and the maximum of the transverse dimension of the handle being between 0.3 and 0.8.

11. The brush as claimed in claim 1 , wherein the longitudinal axis along which the handle extends is rectilinear over a whole length of the handle.

12. The brush as claimed in claim 1 , wherein the longitudinal axis of each bristle is oriented substantially perpendicular to the longitudinal axis of the applicator head, at a base thereof, where it connects to the applicator head.

13. An assembly for applying a product, comprising:
an applicator brush as defined in claim 1 , and
a container containing the product to be applied, selected from a care product for the eyebrows, or a make-up product to be applied to the eyebrows, being in the form of a powder, a gel or a wax.

14. A process for making up the eyebrows, using an assembly as claimed in claim 13 , wherein the product is taken up from the container by means of the applicator brush, and wherein the product is applied to the eyebrows by means of the applicator brush.
