Cosmetic Product Applicator, In Particular for Mascara, and Associated Applicator Assembly

Abstract

An applicator ( 10 ) for cosmetic product, in particular for mascara, having a core ( 12 ) extending in a main direction of longitudinal extension, referred to as an axis of extension (X), and protrusions ( 30 ) projecting from the core ( 12 ) in directions that are substantially radial to the axis of extension (X). The protrusions ( 30 ) are moulded to the core ( 12 ). The free ends of the protrusions ( 30 ) form at least two envelopes (E1, E2) overlapping along the axis of extension (X), a first helical envelope (E1) formed by a first plurality of protrusions ( 31 ) and a second helical envelope (E2) formed by a second plurality of protrusions ( 32 ). The second envelope (E2) from the axis of extension (X), a radial extension that is smaller than the radial extension of the first envelope (E1).

1 . Applicator for cosmetic product, in particular for mascara, comprising a core extending in a main direction of longitudinal extension, referred to as the axis of extension (X), and protrusions projecting from said core in directions that are substantially radial to the axis of extension (X), the protrusions being moulded to the core, characterised in that the free ends of the protrusions form at least two envelopes (E 1 , E 2 ) overlapping along the axis of extension (X), a first helical envelope (E 1 ) formed by a first plurality of protrusions, and a second envelope (E 2 ) formed by a second plurality of protrusions, the second envelope (E 2 ) having, from the axis of extension (X), a radial extension that is smaller than the radial extension of the first envelope (E 1 ). 
     
     
         2 . Applicator according to  claim 1 , wherein said envelopes (E 1 , E 2 ) are in the shape of a screw, around the axis of extension (X), in the shape of a helix having a circular cross section. 
     
     
         3 . Applicator according to  claim 1 , wherein the protrusions of at least one of the envelopes (E 1 , E 2 ) are arranged in rows, referred to as radial rows, the radial rows each being spaced apart from one another along the core ( 12 ). 
     
     
         4 . Applicator according to  claim 3 , wherein a plurality of rows, referred to as mixed rows, of said radial rows comprises protrusions of each of the envelopes (E 1 , E 2 ). 
     
     
         5 . Applicator according to  claim 4 , wherein said mixed rows comprise as many protrusions having the smallest radial extension as protrusions having the largest radial extension. 
     
     
         6 . Applicator according to  claim 1 , wherein the protrusions have a semi-circular cross section. 
     
     
         7 . Applicator according to  claim 1 , wherein the protrusions each have a planar surface. 
     
     
         8 . Applicator according to  claim 7 , wherein the protrusions are positioned such that the planar surfaces of two adjacent protrusions are oriented in the same direction of rotation. 
     
     
         9 . Applicator according to  claim 1 , wherein the core has a constant cross section. 
     
     
         10 . Applicator assembly for cosmetic product, comprising:
 a receptacle comprising a member forming a container intended to contain the cosmetic product, and   an applicator according to  claim 1  that is suitable for being attached to the receptacle, such that the applicator is received inside the container.
