Method Of Manufacturing Applicator For Cosmetics And Applicator Cosmetics

Abstract

A method of manufacturing an applicator ( 1 ) for cosmetics by molding a shank ( 3 ) and a brush bristle ( 5 ) integrally with each other with a mold. The mold comprises a mold ( 7 ) for the shank and a plurality of molds ( 9 ) for brush bristle molding the brush bristle. A plurality of brush grooves ( 11 ) are formed in the surfaces of the molds for brush bristle crossing the axial direction of the shank, the molds for brush bristle are disposed adjacent to each other along the axial direction of the shank, and a resin material is filled in the mold for the shank and the molds for brush bristle for molding.

1 . A method for manufacturing an applicator for cosmetics by molding a shank and a brush bristle integrally with each other with a mold, wherein the mold comprises a mold for the shank molding the shank and a plurality of molds molding the brush bristles, a plurality of brush grooves are formed on surfaces of the molds for brush bristle crossing the axial direction of the shank, the molds for brush bristle are disposed adjacent to each other along the axial direction of the shank, the brush grooves of at least one of the molds for brush bristle disposed adjacent to each other are arranged at positions shifted in the axial direction of the shank, the brush grooves are arranged in a staggered manner along the axial direction of the shank, and a resin material is filled in the mold for the shank and the molds for brush bristle for molding.  
   
   
       2 . The method for manufacturing an applicator for cosmetics according to  claim 1 , wherein the brush grooves are formed on only one side surface of each mold for brush bristle, other side surface is flat shaped, and the one side surface of the mold for brush bristle is fit to the other side surface of the adjacent mold for brush bristle.  
   
   
       3 . (canceled)  
   
   
       4 . The method for manufacturing an applicator for cosmetics according to  claim 1 , wherein the brush grooves of the mold for brush bristle are aligned on substantially the same straight line along the axial direction of the shank.  
   
   
       5 . The method for manufacturing an applicator for cosmetics according to  claim 1 , wherein length of the brush grooves of the adjacent molds for brush bristle differs along the axial direction of the shank.  
   
   
       6 . The method for manufacturing an applicator for cosmetics according to  claim 5 , wherein the length of the brush grooves is gradually increased from a top end portion side to a base end portion side.  
   
   
       7 . An applicator for cosmetics is manufactured by the manufacturing method according to  claim 1.
