Cosmetic product applicator and associated applicator assembly

1. A cosmetic product applicator comprising a brush, the brush comprising:

a core having a longitudinal axis (X), and

a plurality of protrusions projecting from the core,

wherein the protrusions comprise at least one straight first protrusion having a longitudinal axis (x 1 ) oriented in a first radial direction of the core, and at least one bent second protrusion, the bent second protrusion comprising a base portion extending from the core and having a longitudinal axis (x 2 ) oriented in a second radial direction of the core, and an end portion extending from the base portion and having a longitudinal axis (x 4 ) parallel to the longitudinal axis (x 1 ) of the straight first protrusion and wherein the core is hollow as a result of a longitudinal channel arranged inside the core and extending in a longitudinal direction of the core.

2. The applicator according to claim 1 , wherein the protrusions comprise at least one bent third protrusion comprising a base portion extending from the core and having a longitudinal axis (x 3 ) oriented in a third radial direction of the core, and an end portion extending from the base portion and having a longitudinal axis (x 5 ) parallel to the longitudinal axis (x 1 ) of the straight first protrusion, the second and third protrusions being arranged on either side of the straight first protrusion.

3. The applicator according to claim 1 , wherein the protrusions comprise a first row of straight protrusions, a second row of bent protrusions and a third row of bent protrusions, the second row and the third row being arranged on either side of the first row.

4. The applicator according to claim 1 , wherein an angle of between 10° and 60° is formed between the axis of the base portion and the axis of the end portion of the bent protrusion or protrusions.

5. The applicator according to claim 1 , wherein the core has a first end capable of being attached to an applicator rod, and a free second end, and comprises an internal cavity and an end aperture which is located at the second end and communicating with the internal cavity.

6. The applicator according to claim 1 , wherein the core comprises an internal cavity and a wall surrounding the internal cavity, the wall comprising perforated regions having a series of openings made through the wall and communicating with the internal cavity.

7. The applicator according to claim 6 , wherein the openings are diamond shaped and oriented such that a diagonal of a diamond is parallel to the longitudinal axis (X) of the core.

8. The applicator according to claim 6 , wherein the wall has solid regions which extend in a longitudinal direction of the core.

9. The applicator according to claim 1 , wherein the protrusions have free ends which define an enveloping surface (E), the enveloping surface (E) having a rounded part (E 1 ) and a tapered part (E 2 ).

10. An applicator assembly, comprising:

a receptacle comprising a body which forms a container containing a cosmetic product, and

an applicator capable of being attached to the receptacle, that applicator comprising a brush housed within the container, the brush comprising:

a core having a longitudinal axis (X), and

a plurality of protrusions projecting from the core,

wherein the protrusions comprise at least one straight first protrusion having a longitudinal axis (x 1 ) oriented in a first radial direction of the core, and at least one bent second protrusion, the bent second protrusion comprising a base portion extending from the core and having a longitudinal axis (x 2 ) oriented in a second radial direction of the core, and an end portion extending from the base portion and having a longitudinal axis (x 4 ) parallel to the longitudinal axis (x 1 ) of the first straight protrusion and wherein the core is hollow as a result of a longitudinal channel arranged inside the core and extending in a longitudinal direction of the core.

11. The applicator assembly according to claim 10 , wherein the protrusions comprise at least one bent third protrusion comprising a base portion extending from the core and having a longitudinal axis (x 3 ) oriented in a third radial direction of the core, and an end portion extending from the base portion and having a longitudinal axis (x 5 ) parallel to the longitudinal axis (x 1 ) of the straight first protrusion, the second and third protrusions being arranged on either side of the straight first protrusion.

12. The applicator assembly according to claim 10 , wherein the protrusions comprise a first row of straight protrusions, a second row of bent protrusions and a third row of bent protrusions, the second row and the third row being arranged on either side of the first row.

13. The applicator assembly according to claim 10 , wherein an angle of between 10° and 60° is formed between the axis of the base portion and the axis of the end portion of the bent protrusion or protrusions.

14. The applicator assembly according to claim 10 , wherein the core has a first end capable of being attached to an applicator rod, and a free second end, and comprises an internal cavity and an end aperture which is located at the second end and communicating with the internal cavity.

15. The applicator assembly according to claim 10 , wherein the core comprises an internal cavity and a wall surrounding the internal cavity, the wall comprising perforated regions having a series of openings made through the wall and communicating with the internal cavity.

16. The applicator assembly according to claim 15 , wherein the openings are diamond shaped and oriented such that a diagonal of a diamond is parallel to the longitudinal axis (X) of the core.

17. The applicator assembly according to claim 15 , wherein the wall has solid regions which extend in a longitudinal direction of the core.

18. The applicator assembly according to claim 10 , wherein the protrusions have free ends which define an enveloping surface (E), the enveloping surface (E) having a rounded part (E 1 ) and a tapered part (E 2 ).
