Applicator for applying at least one fibre to human keratin materials

Abstract

An applicator for applying at least one fibre to human keratin materials, and in particular for filling out and/or lengthening the eyelashes or eyebrows. The applicator includes at least one channel into which a fibre is inserted, and this channel is defined by at least one portion that, in section, entirely surrounds the fibre and has at least one end-of-travel stop that limits the insertion of the fibre.

1 . An applicator for applying at least one fibre to human keratin materials, having at least one channel into which a fibre is inserted, this channel being defined by at least one portion that, in section, entirely surrounds the fibre and has at least one end-of-travel stop that limits the insertion of the fibre. 
     
     
         2 . The applicator according to  claim 1 , which has a plurality of channels, at least some of which accommodate a fibre, between 2 and 50 channels. 
     
     
         3 . The applicator according to  claim 1 , wherein the inside diameter of each channel is greater than a largest diameter of the fibre that it contains. 
     
     
         4 . The applicator according to  claim 1 , wherein the channels are formed in an elastomeric material, with a Shore A hardness of 0 to 50. 
     
     
         5 . The applicator according to  claim 1 , wherein at least one channel is closed in section along its entire length. 
     
     
         6 . The applicator according to  claim 1 , wherein at least one channel is open in section along a portion of its length less than its total length and around a portion of its circumference less than its total circumference. 
     
     
         7 . The applicator according to  claim 1 , wherein at least some of the channels have the same shape. 
     
     
         8 . The applicator according to  claim 1 , wherein at least some of the channels have different shapes. 
     
     
         9 . The applicator according to  claim 1 , wherein the channels are defined by tubes, the applicator having at least one link connecting the tubes together. 
     
     
         10 . The applicator according to  claim 9 , wherein said at least one link constitutes a flexible articulation between the tubes so as to make it possible to modify the orientation of a tube with respect to an adjacent tube. 
     
     
         11 . The applicator according to  claim 9 , wherein the link makes it possible to join the tubes together by snap-fastening. 
     
     
         12 . The applicator according to  claim 1 , wherein the channels are formed in a monolithic part. 
     
     
         13 . The applicator according to  claim 1 , wherein the fibres are chosen from natural fibres and synthetic fibres. 
     
     
         14 . The applicator according to  claim 1 , wherein the fibres have a largest diameter of between about 50 and 200 μm. 
     
     
         15 . The applicator according to  claim 1 , wherein the fibre protrudes from the channel, through an open outlet thereof, by a length greater than or equal to 1 mm, it being possible for this length to be different for two different fibres. 
     
     
         16 . The applicator according to  claim 15 , wherein the channels are disposed in a fan shape. 
     
     
         17 . The applicator according to  claim 1 , wherein the end-of-travel stop is movable relative to the outlet of the channel through which the fibre emerges. 
     
     
         18 . The applicator according to  claim 1 , wherein the end-of-travel stop is formed by a portion of a monolithic part in which the channels are formed. 
     
     
         19 . A cosmetic treatment process implemented with the aid of an applicator according to  claim 1 , wherein the process comprises the following steps of:
 a) applying an adhesive composition to the area on which the fibre(s) are intended to be deposited and/or to the fibre(s) be applied,   b) bringing the fibre(s) to be applied into contact with said area such that the fibre(s) can adhere to said area,   c) moving the applicator away from said area, the fibre(s) adhering to said area, being withdrawn from the corresponding channel(s) of the applicator.   
     
     
         20 . The process according to  claim 19 , wherein said area is constituted of the eyelid, the eyelashes and/or the eyebrows. 
     
     
         21 . The applicator according to  claim 1 , wherein the applicator is for filling out and/or lengthening the eyelashes and/or eyebrows. 
     
     
         22 . The applicator according to  claim 2 , wherein the number of channels is between 10 and 50. 
     
     
         23 . The applicator according to  claim 1 , wherein the channels are formed in an elastomeric material, with a Shore A hardness of 8 and 40. 
     
     
         24 . The applicator according to  claim 13 , wherein the synthetic fibres are polyamide fibres.
