Title:
長さの異なるファイバを有するマスカラブラシ及びその製造方法
Document Type and Number:
Japanese Patent JP4674028
Kind Code:
B2
Abstract:
A mascara brush is disclosed that has a twisted wire core supporting a plurality of regularly disposed radially extending short and long bristles. The tips of the long bristles define an outer envelope of the brush. The short and long bristles are interspersed such that tips of the short bristles form a layer spaced inwardly from the outer envelope. The brush can be made without regard to bristle stiffness. Because the brush can be made without regard to bristle stiffness, the short bristles can have a degree of flexibility for a given length that is equal to or greater than a degree of flexibility for a given length of the long bristles. The brush is made by first forming a brush blank. The brush blank is made by providing a plurality of bristles of substantially equal length between a pair of parallel wire segments. The wire segments are initially twisted sufficiently to secure the bristles for subsequent steps. After the initial twisting, the bristles having their original lengths define the outer envelope, or the bristles may be trimmed to define the outer envelope and finish the brush blank. The short bristles are formed from a portion of the longer bristles by cutting a series of circumferentially spaced longitudinal grooves in the outer envelope of the brush blank. The wire segments are then further twisted to displace and disperse the short bristles among the long bristles such that the tips of the short bristles define a layer spaced inwardly from the tips of the long bristles.
