Applicator for Cosmetic Product, In Particular Mascara, and Method for Manufacturing Such an Applicator

Abstract

An applicator for cosmetic product, in particular mascara, has a twisted core ( 12 ) and fibres that extend radially from the core ( 12 ) in directions substantially orthogonal to said core. The fibres held by the core ( 12 ). The fibres form at least one envelope (E) by means of their free end, the envelope extending in a longitudinal extension direction around the core ( 12 ), referred to as the main axis X. The envelope (E) has a zone (Z), along the main axis (X), in which the fibres are deflected so as to produce a local deformation (F 1 -F 4 ) of the envelope.

1 . Applicator for cosmetic product, in particular mascara, comprising a twisted core and fibres that extend radially from the core in directions substantially orthogonal to said core, said fibres being held by said core, said fibres forming at least one envelope (E) by means of their free end, said envelope extending in a longitudinal extension direction around said core ( 12 ), referred to as the main axis (X), characterised in that the envelope (E) has a zone (Z), along said main axis (X), in which the fibres are deflected so as to produce a local deformation (F 1 -F 4 ) of the envelope. 
     
     
         2 . Applicator according to  claim 1 , wherein said deflected fibres locally form at least one flattened face (F 1 , F 2 , F 3 , F 4 ) of the envelope (E). 
     
     
         3 . Applicator according to  claim 2 , wherein the flattened face or faces (F 1 , F 2 , F 3 , F 4 ) has/have greater dimensions compared with the parts of the envelope (E) located in the proximity. 
     
     
         4 . Applicator according to  claim 2 , wherein the core has a distal end and a proximal end, the proximal end being opposite the distal end along the main axis (X), said flattened face (F 1 ) being located in the vicinity of the distal end. 
     
     
         5 . Applicator according to  claim 4 , comprising at least two flattened faces (F 1 , F 2 ) arranged to form at least one ridge (C 1 ) in the vicinity of the distal end. 
     
     
         6 . Applicator according to  claim 5 , wherein said ridge (C 1 ) extends the core from the distal end. 
     
     
         7 . Applicator according to  claim 4 , comprising two flattened faces (F 2 , F 3 ) arranged to form a reservoir bordered by two ridges (C 1 , C 2 ) that each comprise one of said flattened faces (F 2 , F 3 ). 
     
     
         8 . Applicator according to  claim 1 , wherein the reservoir is suitable for holding cosmetic product. 
     
     
         9 . Applicator according to  claim 2 , wherein said flattened face (F 1 ) is substantially parallel to a plane including the main axis (X). 
     
     
         10 . Method for manufacturing an applicator for cosmetic product, in particular mascara, said method comprising:
 a step of positioning a plurality of fibres between longitudinal portions of a pin, then   a step of twisting said pin to form a twisted pin having fibres extending radially about said pin, the ends of said fibres forming at least one cylindrical envelope (E) extending in a longitudinal extension direction around said pin, referred to as the main axis (X), then   a step of deforming and heating the fibres such that the envelope (E) has, along said main axis (X), a zone (Z) in which the fibres are deflected so as to produce at least one local deformation of the envelope (E).   
     
     
         11 . Method according to  claim 10 , comprising an additional step between said positioning step and said twisting step, said additional step being a step of offsetting the fibres transversely to the longitudinal portions of the pin so as to form groups of fibres, said groups being offset transversely relative to one another along the pin. 
     
     
         12 . Applicator for cosmetic product, in particular for mascara, obtained using the method according to  claim 10 . 
     
     
         13 . Container for cosmetic product, in particular mascara, comprising an applicator according to  claim 1 .
