  • 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 3 a on which the brush bristles 5 are formed and a rear side of the flat surface 3 a has a curved surface 3 b 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 5 a 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 7 a for a circular portion side molding a circular portion of the shank 3 and a pair of molds 7 b, 7 b 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 mold 7 a for the circular portion side and molds 7 b 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 7 a for the circular portion side and the molds 7 b 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 7 a for the circular portion side and the molds 7 b 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 9 a 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.
  • the mold 9 for brush bristles has the brush grooves 11 in the direction crossing the axial direction of the shank 3 , the side end surface of the bristle 5 is aligned on substantially the same straight line in a direction perpendicular to the axial direction of the shank, so that smooth brushing can be performed when mascara is applied to eyelashes.
  • the brush bristles 5 are arranged in a staggered manner along the axial direction of the shank 3 , mascara can enter between the bristles while moving in a zigzag manner along the axial direction of the shank, resulting in a good application of mascara as compared with the case in which the brush bristles 5 are arranged to be on substantially the straight line along the axial direction of the shank 3 .
