  • FIG 4 is a plane view illustrating essential parts of the mold for the applicator for cosmetics according to the first embodiment of the present invention, respectively.
  • An applicator 1 for cosmetics is mainly used as a mascara brush and includes a shank 3, brush bristles 5 molded integrally with the shank 3.
  • the shank 3 has a flat surface 3a on which the brush bristles 5 are formed and a rear side of the flat surface 3a has a curved surface 3b with a cross section of substantially semicircular shape.
  • the brush bristles 5 are arranged in a staggered manner where three brush bristles 5 and two brush bristles 5 are alternately formed along the axial direction of the shank 3.
  • Each brush bristle 5 has a cross section of substantially triangular shape, and the brush bristles 5 arranged in a direction crossing the axial direction of the shank 3 are formed in such a way that their triangular bottom portions 5a are positioned on a substantially straight line in a direction crossing the axial direction of the shank 3.
  • the mold for molding the applicator 1 for cosmetics includes a mold 7 for the shank molding the shank 3 and a plurality of molds 9 for brush bristles molding the brush bristles 5.
  • the mold 7 for the shank includes a mold 7a for a circular portion side molding a circular portion of the shank 3 and a pair of molds 7b, 7b for a flat portion side molding a flat surface portion of the shank 3.
  • the molds 9 for brush bristles are plate-shaped and each thickness in the axial direction of the shank is about 0. 6 mm.
  • the molds 9 for brush bristles are arranged in the axial direction of the shank 3 and the respective molds 9 for brush bristles are disposed to be adjacent to each other along the axial direction of the shank at the time of molding.
  • each of the molds 9, 9, ... for brush bristles has brush grooves 11 that form a column on the surface of the mold crossing the axial direction of the shank 3.
  • the brush grooves 11 are formed on only one side surface 9a of each of the molds 9 for brush bristles and other surface 9b is flat and the one side surface 9a of the mold 9 for brush bristles is fit onto the other surface 9b of the adjacent mold 9 for brush bristles.
  • a resin material is filled between the end surface 9b of the adjacent mold 9 for brush bristles and the brush grooves 11.
  • the mold 7a for the circular portion side and molds 7b for the flat portion side and the mold 9 for brush bristles are disposed as illustrated in FIG 2, and the resin material is injected in a space 13 formed between the mold 7a for the circular portion side and the molds 7b for the flat portion side from an inflow entrance.
  • the resin material injected in the space 13 enters the brush grooves 11 via the mold 7a for the circular portion side and the molds 7b for the flat portion side and the brush grooves 11 are filled with the resin material, and the space 13 is also filled with the resin material.
  • the resin material is cooled and hardened after the resin material is filled in the space 13 and a predetermined time has passed, thereafter a resultant is extracted from the molds to make it possible to obtain the applicator 1 for cosmetics.
  • the mold 9 for brush bristles since the mold 9 for brush bristles has the brush grooves 11 in the direction crossing the axial direction of the shank 3, the brush grooves 11 can be formed at any position of the surface where the brush grooves are formed, thereby making it possible to increase degree of freedom of the arrangement of brush bristles 5.
  • the brush grooves 11 are formed on only the one side surface 9a of each of the molds 9 for brush bristles, there is no need to adjust the positions of the brush grooves 11 with high precision, thereby making it easy to perform mold positioning as compared with the case in which the brush grooves 11 are formed on both side surfaces of each mold 9 for brush bristles.
