Cosmetic Product Applicator

Abstract

The invention relates to a cosmetic product applicator, including a core forming a winding over at least one turn around a main axis of the applicator and along this axis so as to define an internal convex volume extending from one end of the winding to another end of the winding, and protrusions extending from the core. The applicator is arranged such that no part of the applicator, with the possible exception of certain protrusions, is located in the internal convex volume.

1 . A cosmetic product applicator comprising:
 a core forming a winding over at least one turn around a main axis of the applicator and along this main axis so as to define an internal convex volume extending from one end of the winding to another end of the winding, and   protrusions extending from the core,   the applicator being arranged such that no part of the applicator, with the possible exception of certain protrusions, is located in the internal convex volume.   
     
     
         2 . The applicator according to  claim 1 , wherein the winding of the core is helical. 
     
     
         3 . The applicator according to  claim 1 , wherein the winding of the core has at least two sections with different helix pitches. 
     
     
         4 . The applicator according to  claim 1 , wherein the core forms less than ten turns around the main axis. 
     
     
         5 . The applicator according to  claim 1 , wherein at least some of the protrusions form a single piece with the core. 
     
     
         6 . The applicator according to  claim 1 , wherein at least some of the protrusions have different lengths between each other. 
     
     
         7 . The applicator according to  claim 1 , wherein the core has an inner side directed towards the main axis and an outer side directed away from the main axis, some of the protrusions which extend from the inner side being longer than some of the protrusions which extend from the outer side. 
     
     
         8 . The applicator according to  claim 7 , wherein the protrusions extending from the inner side are between 1 and 5 mm long. 
     
     
         9 . The applicator according to  claim 7 , wherein the protrusions extending from the outer side are between 0.5 and 1 mm long. 
     
     
         10 . The applicator according to  claim 1 , wherein at least some of the protrusions are elongated and straight and extend in planes perpendicular to the axis. 
     
     
         11 . The Applicator according to  claim 1 , forming a cosmetic product applicator for the skin, the nails, the lips, the eyelashes or the eyebrows or forming a mascara applicator. 
     
     
         12 . A cosmetic article comprising an applicator according to  claim 1 . 
     
     
         13 . A method of manufacturing by additive synthesis an applicator, comprising the following steps:
 obtaining data concerning the applicator, the applicator comprising a core forming a winding over at least one turn around a main axis of the applicator and along this main axis so as to define an internal convex volume extending from one end of the winding to another end of the winding, and protrusions extending from the core, the applicator being arranged such that no part of the applicator, with the possible exception of certain protrusions, is located in the internal convex volume; and   additive synthesis of the applicator using the data.   
     
     
         14 . An electronic storage medium comprising stored data to implement the method according to  claim 13 . 
     
     
         15 . A method of placing on a telecommunications network a computer file comprising data suitable for use by a computer program for controlling the implementation of the method according to  claim 13 , in order to download it. 
     
     
         16 . The applicator according to  claim 1 , wherein the core forms less than six turns around the main axis. 
     
     
         17 . The applicator according to  claim 1 , wherein the core forms less than four turns around the main axis. 
     
     
         18 . The applicator according to  claim 1 , wherein all of the protrusions form a single piece with the core. 
     
     
         19 . The applicator according to  claim 7 , wherein all the protrusions which extend from the inner side being longer than all the protrusions which extend from the outer side.
