Abstract
Mascara brush construction composed of a plurality of radially extending bristle filaments fastened in brush formation by a helically twisted metallic wire core. The bristles are tubular or hollow polyamide filaments, each crimped at the midpoint of its length by portions of the helically twisted wire so that the filament halves flare outward in various directions from the brush core. In an alternate embodiment the filaments are noncircular in cross-section and include a plurality of longitudinal, radially extending flange portions.
Claims5
Applicator brush for liquid-type cosmetics comprising a core and bristle portion having a bristle face of generally circular configuration, said core being formed by lengths of metallic wire helically twisted together, said bristle portion being formed by a plurality of bristles extending radially from said core, pairs of said bristles being formed by discrete synthetic plastic filaments that are tubular or have irregularly shaped cross-sections and which are gripped medially of their outer ends by the twisted lengths of wire, the cross-sectional configuration and stiffness of said filaments being such that the gripping thereof will cause said filaments to be crimped so that the filaments flare outwardly in various directions from said core whereby the tip portions of said bristles are generally uniformly distributed throughout said bristle face.
