Applicator for Cosmetic Product, Method for Obtaining an Applicator, and Associated Applicator Assembly

Abstract

An applicator ( 10 ) for a cosmetic product has a core ( 12 ) extending in a main longitudinal extension direction, which is referred to as the main direction (X). The core ( 12 ) has two twisted metal strands. The applicator ( 10 ) further has a plurality of fibres held on the core ( 12 ) by the twisted strands. The twisted strands form non-contiguous turns ( 14, 14′, 15 ) so as to accommodate the fibres, the number and/or the type of the fibres varying from one turn, which is referred to as the first turn ( 14, 14′ ), to the other, which is referred to as the second turn ( 15 ).

1 . Applicator for cosmetic product, comprising a core extending in a main longitudinal extension direction, which is referred to as the main direction (X), said core comprising two twisted metal strands, said applicator further comprising a plurality of fibres held on the core by said twisted strands, said applicator being characterised in that said twisted strands form non-contiguous turns so as to accommodate said fibres, the number and/or the type of the fibres varying from one turn, referred to as the first turn, to the other, referred to as the second turn. 
     
     
         2 . Applicator according to  claim 1 , comprising a plurality of first turns and a plurality of second turns along said main direction (X). 
     
     
         3 . Applicator according to  claim 2 , wherein said plurality of first turns comprises fibres of a first, hollow type (A), and fibres of a second, solid type (B). 
     
     
         4 . Applicator according to  claim 2 , wherein said plurality of second turns comprises only fibres of a first, hollow type. 
     
     
         5 . Applicator according to  claim 4 , having a proximal end which extends through a region with no fibres, and a distal end which is opposite said proximal end in the main direction (X), said plurality of first turns defining, starting from said proximal end, a first region (Z 1 ) along said main direction (X). 
     
     
         6 . Applicator according to  claim 5 , wherein said first region (Z 1 ) comprises a number of turns which is in the range of [8; 12]. 
     
     
         7 . Applicator according to  claim 5 , wherein said first region (Z 1 ) comprises a number of fibres which is in the range of [1100; 1500]. 
     
     
         8 . Applicator according to  claim 7 , wherein said first region (Z 1 ) comprises a number of fibres of the first, hollow type (A) which is in the range of [500; 700], and a number of fibres of the second, solid type (B) which is in the range of [600; 800]. 
     
     
         9 . Applicator according to  claim 5 , wherein the plurality of second turns is located between said first region (Z 1 ) and said distal end, thus defining a second region (Z 2 ) along said main direction (X). 
     
     
         10 . Applicator according to  claim 9 , wherein said second region (Z 2 ) comprises a number of turns ( 15 ) which is in the range of from 3 to 5. 
     
     
         11 . Applicator according to  claim 9 , wherein said second region (Z 2 ) comprises a number of fibres which is in the range of [150; 250]. 
     
     
         12 . Applicator according to  claim 9 , wherein said first region (Z 1 ) has turns which are spaced apart by a first pitch (p 1 ), and said second region (Z 2 ) has turns ( 15 ) which are spaced apart by a second pitch (p 2 ), said first pitch (p 1 ) being greater than said second pitch (p 2 ). 
     
     
         13 . Method for obtaining an applicator for cosmetic product, comprising:
 a) a step of distributing a plurality of fibres between two metal strands, said two strands extending in a main longitudinal extension direction, which is referred to as the main direction (X), the density and/or the type of the fibres distributed between said two strands varying along said main direction (X),   b) a single step of twisting said two strands so as to form non-contiguous turns along said main direction so as to form a substantially cylindrical envelope using the free ends of said fibres, the twisting force applied to said strands being uniform along said main direction (X).   
     
     
         14 . Method according to  claim 13 , further comprising a step of cutting the free ends of said fibres so as to form cavities in the region of turns comprising fibres of a first, hollow type (A), and peaks in the region of turns comprising fibres of a second, solid type (B). 
     
     
         15 . Applicator assembly for cosmetic product, comprising:
 a receptacle comprising a body forming a container which is intended to contain the cosmetic product, and   an applicator according to  claim 1 , which is capable of being attached to the receptacle in such a way that said applicator is accommodated inside the container.   
     
     
         16 . Applicator assembly for cosmetic product, comprising:
 a receptacle comprising a body forming a container which is intended to contain the cosmetic product, and   an applicator obtained according to  claim 13 , which is capable of being attached to the receptacle in such a way that said applicator is accommodated inside the container.
