Abstract

Selon l'invention, une brosse à mascara comprend une partie centrale composée au moins de deux sections en fil métallique (12, 13) torsadées entre elles le long d'un axe longitudinal d'âme en fil métallique (LD) et d'une garniture de poils (26) composée de poils (1) en matière plastique formés de filaments, lesquels poils sont maintenus par serrage respectivement entre les deux sections en fil métallique (12, 13) et sont réalisés, sur leurs extrémités libres, avec ou sans pointe de poil en forme de coin. Les poils sont formés en particulier au moins en partie à partir de filaments creux à l'intérieur. L'invention vise à proposer une solution permettant d'améliorer la distribution de masse par rapport aux applicateurs connus. A cet effet, en particulier au moins les poils réalisés de manière creuse à l'intérieur comportent, sur leurs extrémités libres radialement extérieures, une découpe oblique (3) à la manière d'un simple coin et comprennent une pointe de poil en forme de coin, pourvue au moins d'une face de découpe (4) réalisant un coin.
