Brush for applying a product to the eyelashes or eyebrows

Abstract

The present invention relates to a brush for applying a product to the eyelashes and/or eyebrows, comprising: —a core, notably a twisted core, that extends along a curved longitudinal axis, and —bristles that are held by the core, the core comprising a portion (43) carrying bristles that has a proximal end (40a) intended to be fixed to a stem and a distal end (40b), the bristles having free ends that define an envelope surface, the envelope surface having, before the core is curved, at least one first facet (60) and at least one second facet (45) which are different from one another.

1 : Brush for applying a product to the eyelashes and/or eyebrows, comprising:
 a core that extends along a curved longitudinal axis, and   bristles that are held by the core, the core comprising a portion carrying bristles that has a proximal end intended to be fixed to a stem and a distal end, the bristles having free ends that define an envelope surface,   the envelope surface having, before the core is curved, at least one first facet and at least one second facet which are different from one another.   
     
     
         2 : Brush according to  claim 1 , wherein the first facet is disposed in the hollow of the curvature of the core. 
     
     
         3 : Brush according to  claim 1 , wherein the second facet is smaller than the first facet. 
     
     
         4 : Brush according to  claim 1 , which comprises at least two second facets. 
     
     
         5 : Brush according to  claim 4 , wherein the two facets are symmetrical to one another with respect to a plane containing the longitudinal axis of the core. 
     
     
         6 : Brush according to  claim 1 , wherein the first and second facets form a triangle when the brush is viewed in cross section. 
     
     
         7 : Brush according to  claim 6 , wherein the first and/or second facets, or both facets, are delimited by an edge oriented perpendicularly to the longitudinal axis of the stem at the proximal end of the portion of the core carrying the bristles. 
     
     
         8 : Brush according to  claim 1 , wherein the width of the first facet decreases in the direction of the distal end of the portion of the core carrying the bristles. 
     
     
         9 : Brush according to  claim 1 , wherein the envelope surface has, before the core is curved, an at least partially frustoconical or ogival overall shape. 
     
     
         10 : Brush according to  claim 1 , wherein the envelope surface comprises a distal frustoconical portion having a cross section that decreases towards the free end of the core. 
     
     
         11 : Brush according to  claim 1 , wherein the envelope surface comprises a cylindrical central portion situated between a distal frustoconical portion and a proximal frustoconical portion. 
     
     
         12 : Brush according to  claim 1 , wherein the envelope surface has at least one cross section of circular shape situated at the distal end. 
     
     
         13 : Brush according to  claim 12 , wherein the distal end of the core is situated on the longitudinal axis of a stem to which it is attached. 
     
     
         14 : Brush according to  claim 1 , wherein the core is fixed by its proximal end to a stem. 
     
     
         15 : Packaging and application device comprising a container containing a product to be applied and a brush according to  claim 1 .
