- the brush groove of the plush hair mold can be on the same straight line along the axial direction of the handle.
- the same brush bristle mold can be used, and at the time of molding as compared with different types of brush bristle molds.
- the arrangement of the brush bristle mold is easy.
- the brush grooves of adjacent brush hair molds may have different lengths along the axial direction of the handle. In this case, since the length of the brush groove of the adjacent brush hair mold is different along the axial direction of the handle, the brush hair can be applied according to the length of the eyelashes and eyebrows, and the cosmetic material can be applied. Can be applied evenly.
- the brush groove may be gradually elongated from the distal end side in the axial direction of the handle toward the proximal end side. In this case, since the brush groove is gradually longer from the distal end side to the proximal end side in the axial direction of the handle, a right-handed person can easily apply cosmetic material to the right eyelash. Become.
- the second invention is a cosmetic applicator obtained by the above production method. In this case, the same effect as the above manufacturing method can be obtained.
- FIG. 1 is a perspective view showing a main part of a mold of the cosmetic applicator according to the first embodiment.
- FIG. 2 is a cross-sectional view showing a mold of a cosmetic applicator.
- FIG. 3 is a perspective view showing a main part of the cosmetic applicator according to the first embodiment.
- FIG. 4 is a plan view showing a main part of the cosmetic applicator according to the first embodiment.
- FIG. 5 is a perspective view showing the main part of the mold of the cosmetic applicator according to the second embodiment.
- FIG. 6 is a schematic cross-sectional view showing a production example of the color-modified titanium oxide powder of the present invention.
- FIG. 9 is a plan view showing a main part of a cosmetic applicator according to a modification.
- FIG. 8 is a plan view showing a main part of a cosmetic applicator according to a modification.
- FIG. 2 is a perspective view showing a main part of a mold of a cosmetic applicator according to the first embodiment
- FIG. 2 is a cross-sectional view showing a mold of the cosmetic applicator
- FIG. 3 is a cosmetic application according to the first embodiment
- FIG. 4 is a plan view showing the main part of the cosmetic applicator according to the first embodiment.
- the cosmetic applicator 1 according to the present embodiment is mainly used as a mascara brush, and includes a handle 3 and brush hairs 5 formed integrally with the handle 3.
- the handle 3 has a flat surface 3a on which the brush bristles 5 are provided, and the back side of the flat surface 3a has a curved surface 3b having a substantially semicircular cut surface.
- the brush bristles 5 are arranged in a staggered pattern in which three brush bristles 5 and two brush bristles 5 are alternately provided along the axial direction of the handle 3.
- the brush bristles 5 have a substantially triangular cross section, and each of the bristles 5 arranged in a direction intersecting with the axial direction of the handle 3 is substantially straight in a direction where the base 5a of the triangular shape intersects with the axial direction of the handle
- the mold for molding the cosmetic applicator 1 is composed of a pattern mold 7 for molding the pattern 3 and a plurality of brush hair molds 9 for molding the brush hair 5.
- the pattern mold 7 is composed of an arc-shaped part side mold 7 a for forming the arc-shaped part of the pattern 3 and a pair of flat surface part-side molds 7 b and 7 b for forming the flat surface part of the handle 3. Have been.
- the brush bristle mold 9 is plate-shaped, and the axial thickness of the handle is about 0.6 mm.
- the brush bristle dies 9 are provided side by side in the axial direction of the handle 3, and at the time of molding, the brush bristle dies 9 are arranged adjacent to each other in the axial direction of the handle.
- Each of the bristle molds 9, 9,... Has a brush groove 11 formed in a row on a surface that intersects the axial direction of the handle 3.
- the brush groove 11 is formed only on one side 9a of each brush bristle mold 9, the other side 9b is flat, and the one side 9a of the brush bristle mold 9 is connected to the adjacent bristle. Aligned with the other side surface 9 b of the mold 9 for lashi hair.
