摘要：
The invention relates to an applicator end piece (1) for applying a cosmetic product, which extends along a longitudinal extension direction (X), known as the main direction (X), and comprises: an external shell (3) having an external surface and an internal surface, the external surface defining at least one application part, the internal surface delimiting a cavity (5); a central element (7) disposed inside the cavity (5), in at least one position, the internal surface (3i) of the external shell (3) being at a distance from the central element (7) in a direction orthogonal to the longitudinal extension direction and in the longitudinal direction so as to define a free space enclosing the central element (7).
权利要求：
1. Applicator end piece (1) for cosmetic product extending along a longitudinal extension direction (X), called principal direction (X), and comprising: - an external shell (3) having an external surface (3e) and an internal surface (3i), the external surface (3e) defining at least one application part, the internal surface (3i) delimiting a cavity (5), - a central element (7) arranged inside the cavity (5), in at least one position, the internal surface (3i) of the external shell (3) is spaced from the central element (7) in a direction orthogonal to the longitudinal extension direction and in the longitudinal direction so as to define a free space enclosing the central element (7).
2. Applicator end piece (1) according to the preceding claim 1, wherein the central element (7) is arranged entirely inside the cavity (5).
3. Applicator end piece (1) according to any one of the preceding claims, wherein the external shell (3) comprises at least one orifice (19, 25, 27), the free space enclosing the central element (7) allows a movement of the external shell (3) relative to the central element (7), the movement of the external shell (3) causing the cosmetic product to enter and/or exit through the at least one orifice (19, 25, 27).
4. Applicator end piece (1) according to any one of the preceding claims, wherein the external shell (3) comprises a plurality of orifices (19, 25, 27).
5. Applicator end piece (1) according to any one of claims 3 or 4, wherein the at least one application part comprises a first application area (13) extending along the principal direction (X) from a proximal end (1a) to an intermediate position (1c) and a second application area (15) extending along the principal direction (X) from the intermediate position (1c) to a distal end (1b), the at least one orifice (19, 25, 27) is arranged at the level of the first application area (13).
6. Applicator end piece (1) according to the preceding claim, wherein the second application area (15) further comprises at least one orifice (25, 27) with an opening cross-section of a smaller size than the size of the opening cross-section of the orifices (19) of the first application area (13).
7. Applicator end piece (1) according to any one of the preceding claims, wherein the central element (7) is in material connection with the external shell (3) at the level of the distal end (1b) or at the level of the proximal end (1a).
8. Applicator end piece (1) according to any one of the preceding claims, wherein the cavity (5) has a shape complementary to the shape of the external shell (3) and/or the central element (7) has a shape complementary to the shape of the external shell (3) and/or the central element (7) has a shape complementary to the shape of the cavity (5).
9. Applicator end piece (1) according to any one of the preceding claims, wherein the at least one application part is textured.
10. Applicator end piece (1) according to any one of the preceding claims, wherein the applicator end piece (1) is a monolithic piece obtained without assembly and by additive manufacturing.
11. Applicator assembly for cosmetic product, comprising: - a container (33) comprising a body (35) forming a reservoir intended to contain the cosmetic product, and - an applicator end piece (1) for applying the cosmetic product according to one of claims 1 to 10 adapted to be attached to the container (33), so that the applicator end piece (1) is housed inside the reservoir.
12. Method for manufacturing an applicator end piece (1) for applying cosmetic product according to any of claims 1 to 10, the method comprising: - a step of elaborating a digital model of the applicator end piece (1); - a step of manufacturing the applicator end piece (1) by means of the digital model.
