  • Patent number: 5551456
    Abstract: An applicator brush for fluid-type cosmetics, such as may be used in applying mascara to eyelashes which includes a bristle portion disposed at one end of a helical twisted wire core with a handle disposed at the outer end. The configuration of the bristle portion is such that the bristle tips define a generally cylindrical outer surface having two (2) diametrically opposed channels and application surfaces helically disposed along the length of the brush portion which are spiraled about the core to form a helix thereof. The brush portion is formed by disposing the bristles between the lengths of the wire and helically twisting the wire to form the core that retains the bristles therebetween. The bristle portion is then trimmed to a shape of generally rectangular cross-section. To form the helical application surface, the wire core is further twisted in the same direction a predetermined number of turns.
