Applicator for cosmetic product, in particular mascara, and associated applicator assembly

Abstract

An applicator for a cosmetic product includes a sleeve extending along a longitudinal axis (X), a core, and a plurality of protrusions. The core extends along a main axis (Y) from a first proximal end to a second opposite and free distal end. The main axis (Y) is entirely contained in one plane and comprising a single concave curvature towards a first side. The plurality of protrusions extends projectingly from the core towards a free end defining an envelope surface. The envelope surface has a cross-section along the main axis (Y) of continuous oblong shape along the entire length of the core and decreasing surface area from the proximal end to the distal end.

1 . An applicator for cosmetic product, comprising:
 a sleeve extending along a longitudinal axis (X),   a core extending along a main axis (Y) from a first proximal end towards a second opposite and free distal end, the main axis (Y) being entirely contained in a plane and comprising a single concave curvature towards a first side, and   a plurality of protrusions extending projectingly from the core towards a free end defining an envelope surface,   
       wherein the envelope surface has a cross-section along the main axis of continuous oblong shape over the entire length of the core and of decreasing surface area from the proximal end towards the distal end. 
     
     
         2 . The applicator according to  claim 1 , wherein the protrusions arranged on the first side and/or on an opposite second side have a greater average height than the protrusions located on third and/or fourth sides opposite each other and adjacent to the first and second sides. 
     
     
         3 . The applicator according to  claim 1 , wherein the core comprises a first rectilinear proximal portion forming an angle (α) with respect to the sleeve, referred to as the first rectilinear portion, and a second adjacent portion having the concave curvature, referred to as the second curved portion. 
     
     
         4 . The applicator according to  claim 1 , wherein the core has a decreasing surface cross-sectional area from the proximal end to the distal end. 
     
     
         5 . The applicator according to  claim 1 , wherein the main axis (Y) of the core does not cross the longitudinal axis of the sleeve. 
     
     
         6 . The applicator according to  claim 1 , wherein at least some of the protrusions have a decrease in height along the core from the proximal end towards the distal end. 
     
     
         7 . The applicator according to  claim 6 , wherein the decrease of the protrusions is rectilinear. 
     
     
         8 . The applicator according to  claim 3 , wherein the second curved portion comprises a single vertex located on a section extending between the middle of the core and the distal end. 
     
     
         9 . The applicator according to  claim 3 , wherein the first rectilinear portion extends from the proximal end of the core towards the middle of the core. 
     
     
         10 . The applicator according to  claim 3 , wherein the angle (α) between the sleeve and the first rectilinear portion is between 5 and 30°. 
     
     
         11 . The applicator according to  claim 3 , wherein the core further comprises a third rectilinear distal portion adjacent to the second curved portion and forming an angle (β) with respect to the sleeve, referred to as the third rectilinear portion. 
     
     
         12 . The applicator according to  claim 1 , wherein the protrusions are arranged in the form of longitudinal rows, the rows being substantially parallel to the main axis (Y). 
     
     
         13 . The applicator according to  claim 12 , wherein the average height of the protrusions of the longitudinal rows of the first side and of the second side is greater than the average height of the protrusions of the longitudinal rows of the third side and of the fourth side. 
     
     
         14 . The applicator according to  claim 12 , wherein the number of longitudinal rows on the first and second sides is greater than the number of longitudinal rows on the third and fourth sides. 
     
     
         15 . The applicator according to  claim 1 , wherein the protrusions extend in a direction at an angle with respect to a direction perpendicular to the surface of the core. 
     
     
         16 . An applicator assembly for cosmetic product, comprising:
 a container comprising a body forming a reservoir for containing the cosmetic product, and   an applicator of the cosmetic product according to  claim 1  adapted to be attached to the container, so that the applicator is housed inside the reservoir.
