Applicator device for applying a fluid or pasty product to keratin fibers

Abstract

The present invention relates to an applicator device for applying a fluid or pasty product to keratin fibres, including an elongate core ( 1 ) extending according to a longitudinal axis XX and spikes ( 2 ) embedded at a first end ( 20 ) on the exterior surface of the core, the second ends ( 21 ) of said spikes being free. According to the invention, ail or some of said spikes ( 2 ) are provided on their exterior surface with at least one protuberance or hook ( 3 ) placed at a distance D from the first end ( 20 ) of the spike, the distance D being less than around 75% of the length of the spike ( 2 ).

1 . Applicator device for applying a fluid or pasty product to keratin fibres, including an elongate core ( 1 ) extending according to a longitudinal axis XX and spikes ( 2 ) embedded at a first end ( 20 ) on the exterior surface of the core ( 1 ), the second ends ( 21 ) of said spikes being free, characterized in that all or some of the spikes ( 2 ) are provided on their exterior surface with at least one protuberance or hook ( 3 ) placed at a distance D from the first end ( 20 ) of the spike, the distance D being less than around 75% of the length of the spike ( 2 ). 
     
     
         2 . Applicator device according to  claim 1 , characterized in that the distance D is measured between the first end ( 20 ) of the spike ( 2 ) and the surface or line of the hook closest to the core, and is greater than or equal to around 0.02 millimetres. 
     
     
         3 . Applicator device according to  claim 1 , characterized in that the longitudinal axis XX of the core ( 1 ) is not straight. 
     
     
         4 . Applicator device according  claim 1 , characterized in that the core ( 1 ) has a constant transverse cross-section over its length. 
     
     
         5 . Applicator device according to  claim 1 , characterized in that the lengths of said spikes ( 2 ) implanted on the core ( 1 ) are such that the spikes form a substantially cylindrical external volume. 
     
     
         6 . Applicator device according to  claim 1 , characterized in that the lengths of said spikes ( 2 ) implanted on the core ( 1 ) are such that the spikes together form an oval ball- or barrel-shaped volume. 
     
     
         7 . Applicator device according to  claim 1 , characterized in that said spikes ( 2 ) form at least one aligned row substantially parallel to the axis XX of the core. 
     
     
         8 . Applicator device according to  claim 1 , characterized in that said spikes ( 2 ) form part of a plane perpendicular or substantially perpendicular to the longitudinal axis XX of the core. 
     
     
         9 . Applicator device according to  claim 1 , characterized in that the distance D is around one-third the total length of the spike ( 2 ). 
     
     
         10 . Applicator device according to  claim 1 , characterized in that said hooks ( 3 ) have a flat right triangle shape in which a first face of the right angle coincides with the exterior surface of the spike and a second face of the right angle is close to the exterior surface of the core. 
     
     
         11 . Applicator device according to  claim 1 , characterized in that the spikes ( 2 ), the hooks ( 3 ) and the core ( 1 ) are produced in a single layer.
