Abstract

L'invention fournit un instrument d'application pour maquillage qui se révèle à la fois excellent dans sa fonction pour peigner les cils et les sourcils à l'aide d'une partie brosse, et dans sa fonction pour appliquer une matière de maquillage, quel que soit le degré de viscosité (propriétés de viscosité) d'une matière liquide de maquillage à appliquer. Cet instrument d'application pour maquillage est équipé : d'un axe de brosse (14) dont une partie extrémité de base sert de partie de manipulation (15); et de la partie brosse (16) dans laquelle des dents de peigne (17) aplaties qui se prolongent dans une direction perpendiculaire à l'axe de brosse (14) sur une face latérale côté extrémité avant de l'axe de brosse (14), sont rangées selon un pas prédéfini dans la direction axiale. Des rainures latérales (18) qui s'étendent dans une direction perpendiculaire à la direction de prolongement des dents de peigne (17), sont formées sur la face latérale des dents de peigne (17). La surface de contact des dents de peigne (17) avec la matière de maquillage est réduite, du fait de l'intervalle relativement grand entre les dents de peigne (17) de manière à s'adapter à l'application d'une matière de maquillage très visqueuse. La fonction de la partie brosse (16) de conservation d'une matière de maquillage faiblement visqueuse, est réduite, toutefois, les rainures latérales (18) formées sur la face latérale des dents de peigne (17) compensent la diminution de surface de contact des dents de peigne (17) avec la matière de maquillage, et la partie brosse (16) peut conserver une grande quantité de matière de maquillage faiblement visqueuse.
