CA 2607255

A bristle brush for applying a cosmetic product to hair is provided with a sleeve having a longitudinal axis and at least one perforation. The brush is disposed within the sleeve so that brush bristles extend through the perforation for contact with the hair. The perforation is circular, arcuate, rectangular, square, triangular or trapezoidal in shape or at an angle with respect to the longitudinal axis of the sleeve. When the sleeve has a plurality of perforations, the perforations can be shaped alike or can differ in shape and/or in angle with respect to the longitudinal axis of the sleeve so that one or more predetermined performance characteristics are obtained when the brush is used to apply the cosmetic product to the hair. A method for adjusting brush performance characteristics is also disclosed.

L'invention concerne un pinceau permettant d'appliquer un produit cosmétique sur des parties du système pileux. Ce pinceau est pourvu d'un manchon ayant un axe longitudinal et au moins un orifice. Le pinceau est disposé dans le manchon de façon que les crins du pinceau traversent l'orifice pour entrer en contact avec les poils. L'orifice est circulaire, arqué, rectangulaire, carré, triangulaire ou trapézoïdal ou forme un certain angle par rapport à l'axe longitudinal du manchon. Lorsque le manchon comporte une pluralité d'orifices, les orifices peuvent être de forme similaire ou présenter une forme et/ou un angle différents par rapport à l'axe longitudinal du manchon de façon à obtenir une ou plusieurs caractéristiques prédéterminées de rendement lorsque le pinceau est utilisé pour appliquer le produit cosmétique sur les poils. L'invention concerne également un procédé permettant de régler les caractéristiques de rendement du pinceau.
