Abstract

The invention relates to an applicator for a cosmetic product including a first part and a second part that extend along a longitudinal direction of extension from a proximal end towards a free distal end of the applicator, the first part and the second part being configured to form parts for applying the cosmetic product, one of the parts is mounted mobile in for translational with respect to the other of the parts, from at least a first retracted position, to a second deployed position, the first and second parts are configured to form together a variable volume reservoir, intended to contain the cosmetic product and that has a first volume when the parts occupy the first retracted position and a second volume when the parts occupy the second deployed position.

First claim

The invention claimed is:

1. An applicator for a cosmetic product, comprising a first part and a second part that extend along a direction of longitudinal extension from a proximal end to a free distal end of the applicator,
the first part and the second part being configured to form parts for applying the cosmetic,
one of the parts is mounted mobile in translational with respect to the other of said parts; and while the first part and the second part are engaged such that the first part and the second part are positionable between a retracted position and a deployed position at least during the application of the cosmetic product,
wherein, in both the retracted position and the deployed position, the first part and the second part together define an interior cavity within the applicator for holding the cosmetic product, wherein the interior cavity has a first volume when the first part and the second part are in the retracted position and a second volume when the first part and the second part are in the deployed position,
each of the first and second parts comprises at least two longitudinal branches, the at least two longitudinal branches of the first part being circumferentially alternated with the at least two longitudinal branches of the second part, the branches of the first part and the branches of the second part at least partially defining the interior cavity; and,
each of the first and second parts comprises at least one opening arranged between two consecutive branches, the opening enabling both a passage of a branch of the other part and a distribution of the cosmetic product through the opening from the interior cavity.

2. The applicator according to claim 1 , wherein each part is a single monolithic part.

3. The applicator according to claim 1 , wherein said applicator is produced without assembly operations.

4. The applicator according to claim 1 , wherein the opening has a width greater than the width of the branch passing through the opening so as to enable a rotational range of motion of the part that is mobile with respect to the other part.

5. The applicator according to claim 1 , wherein all or at least a part of said branches comprises at least one row of protrusions protruding and extending radially along the longitudinal extension.

6. The applicator according to claim 5 , wherein the first part has a free distal end provided with protrusions and a proximal end arranged in the internal volume of the second part and the second part has a free distal end not provided with protrusions and arranged in the internal volume of the first part.

7. The applicator according to claim 5 , wherein the applicator is produced by additive manufacturing and said protrusions are integrally formed with said branches.

8. The applicator according to claim 1 , wherein the proximal end of the second part is configured to be secured to a rod of the applicator and the proximal end of the first part is free and the first part is mobile in translation with respect to the second part.

9. The applicator according to claim 1 , wherein the proximal end of the first part is configured to be secured to a rod of the applicator, the proximal end of the second part is free and comprises an orifice crossed by the proximal end of the first part and the second part is mobile in translation with respect to the first part.

10. An applicator assembly for a cosmetic product, comprising:
a container comprising a body forming a reservoir intended to contain the cosmetic product, and
an applicator for a cosmetic product adapted to be secured to the container, so that the applicator is housed inside the reservoir, the applicator, comprising a first part and a second part that extend along a direction of longitudinal extension from a proximal end to a free distal end of the applicator,
the first part and the second part being configured to form parts for applying the cosmetic,
one of the first part or the second part is mounted mobile in translational with respect to the other of said first part or the second part, at least during the application of the cosmetic product, from at least a retracted position, to a deployed position,
wherein, in both the retracted position and the deployed position, the first part and the second part together define an interior cavity within the applicator for holding the cosmetic product,
each of the first and second parts comprises at least two longitudinal branches, the at least two longitudinal branches of the first part being circumferentially alternated with the at least two longitudinal branches of the second part, the branches of the first part and the branches of the second part at least partially defining the interior cavity; and,
wherein each of the parts is hollow, so as to define the interior cavity when the first part and the second part are engaged in each other
each of the first and second parts comprises at least one opening arranged between two consecutive branches, the opening enabling a passage of a branch of the other part and distribution of the cosmetic product.
