Applicator for cosmetic product, and associated applicator assembly

Abstract

The invention relates to an applicator ( 10 ) for a cosmetic product comprising a core ( 11 ) extending along a main longitudinal extension direction (X), referred to as main direction, and a plurality of protrusions ( 12 ) projecting from the core ( 11 ), the core ( 11 ) comprising a plurality of flexible zones ( 13 a, 13 b ) arranged in succession along the main direction (X), on which the core ( 11 ) is thinned according to a thinning axis ( 14 a, 14 b ) substantially orthogonal relative to the main direction (X) so as to form two cavities ( 15 a, 15 b ) that are radially opposed relative to said main direction (X), the applicator ( 10 ) comprising at least one flexible zone ( 13 a, 13 b ) having a thinning axis ( 14 a, 14 b ) that is angularly offset relative to the thinning axis ( 14 b, 14 a ) of a flexible zone ( 13 b, 13 a ) adjacent thereto.

1 . An applicator for cosmetic product comprising:
 a core extending along a main longitudinal extension direction, referred to as the main direction, and   a plurality of protrusions projecting from the core,   the core comprising a plurality of flexible zones arranged in succession along the main direction, at which the core is thinned according to a thinning axis substantially orthogonal relative to the main direction, so as to form two cavities that are radially opposed relative to said main direction,   the applicator comprising at least one flexible zone having a thinning axis angularly offset relative to the thinning axis of a flexible zone adjacent thereto.   
     
     
         2 . The applicator according to  claim 1 , further comprising an alternation of first flexible zones of which the thinning axes are parallel to one another and of second flexible zones of which the thinning axes are parallel to one another and angularly offset relative to the thinning axes of the first flexible zones. 
     
     
         3 . The applicator according to  claim 2 , wherein one flexible zone out of two, along the main direction, is a first flexible zone and wherein one flexible zone out of two, along the main direction, is a second flexible zone. 
     
     
         4 . The applicator according to  claim 2 , wherein the offset angle (α) formed between the thinning axes of the first and second flexible zones is between 45 and 135°, preferably about 90°. 
     
     
         5 . The applicator according to  claim 1 , wherein the flexible zones are located on a discrete portion of the main direction of the core. 
     
     
         6 . The applicator according to  claim 1 , wherein:
 the core comprises, along the main direction, a proximal portion extended by a sleeve without protrusions, a distal portion opposite the proximal portion along the main direction and a median portion that connects the proximal portion and the distal portion;   the flexible zones are located in the vicinity of the distal portion of the core.   
     
     
         7 . The applicator according to  claim 1 , wherein the cavities of the flexible zones are symmetrical relative to a plane substantially orthogonal to the thinning axis associated with said flexible zone and comprising the main direction. 
     
     
         8 . The applicator according to  claim 1 , wherein:
 the core comprises, along the main direction, a proximal portion extended by a sleeve without protrusions, a distal portion opposite the proximal portion along the main direction and a median portion that connects the proximal portion and the distal portion;   the core comprises a free end in the vicinity of the distal portion, said free end having, along the main direction, a shape comprising a sloped section so as to limit the caking of cosmetic product on said free end.   
     
     
         9 . An applicator assembly for cosmetic product, comprising a container comprising a body forming a reservoir intended to contain the cosmetic product, and an applicator configured to be displaced with respect to the container between a closed position of the assembly in which the applicator is fastened onto the container and the applicator is housed inside the reservoir, and an open position of the assembly in which the applicator releases the container and the applicator is arranged outside the reservoir, the applicator comprising:
 a core extending along a main longitudinal extension direction, referred to as the main direction, and   a plurality of protrusions projecting from the core,   the core comprising a plurality of flexible zones arranged in succession along the main direction, at which the core is thinned according to a thinning axis substantially orthogonal relative to the main direction, so as to form two cavities that are radially opposed relative to said main direction,   the applicator comprising at least one flexible zone having a thinning axis angularly offset relative to the thinning axis of a flexible zone adjacent thereto.
