Abstract
Abstract A mascara brush comprises a plurality of radially extending bristle filaments (22) fastened in brush formation by a helically twisted metallic wire core (10). The bristles are tubular (24 - Figure 5) 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 (26 - Figure 6) are non-circular in cross-section and include a plurality of longitudinal, radially extending flange portions (28).

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
107 words
Applicator brush for liquid-type cosmetics comprising a core and bristle portion having a cylindrical bristle face, 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 synthetic plastic filaments which are gripped at their midpoints by said twisted lengths of wire, said filaments having cross-sectional configuration such that the gripping thereof will cause said filaments to be crimped so that the filaments extend in various directions from said core whereby the tip portions of said bristles are uniformly distributed throughout said bristle face.
Claim 2
Dependent Claim
107 words
Applicator brush for liquid-type cosmetics comprising a core and bristle portion having a cylindrical bristle face, 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 synthetic plastic filaments which are gripped at their midpoints by said twisted lengths of wire, said filaments having cross-sectional configuration such that the gripping thereof will cause said filaments to be crimped so that the filaments extend in various directions from said core whereby the tip portions of said bristles are uniformly distributed throughout said bristle face.

Claim 7
Dependent Claim
82 words
An applicator brush for cosmetics comprising an elongate core with bristles extending radially from it, the core being formed of lengths of wire twisted together, the bristles being formed of plastics filaments gripped at their midpoint by the twisted lengths of wires characterised in that the cross-section of at least some of the filaments is hollow or non-circular such that the filaments extend in various directions from the core and the tips of the bristles are uniformly distributed throughout the bristle face.
Claim 8
Dependent Claim
82 words
An applicator brush for cosmetics comprising an elongate core with bristles extending radially from it, the core being formed of lengths of wire twisted together, the bristles being formed of plastics filaments gripped at their midpoint by the twisted lengths of wires characterised in that the cross-section of at least some of the filaments is hollow or non-circular such that the filaments extend in various directions from the core and the tips of the bristles are uniformly distributed throughout the bristle face.
