Definitions
- the present invention relates to a cosmetic applicator and, in particular, to an applicator for applying liquid cosmetics, such as mascara, to eyelashes or other parts of the body.
- an applicator or brush The general purpose of an applicator or brush is to pick up an adequate supply of material, such as mascara, from a container, carry it from the reservoir of the container without dripping, and apply it evenly to the particular area of the body, such as, for example, eyelashes. This needs to be achieved without depositing lumps or blobs of the material on the eyelashes.
- material such as mascara
- the bristle ends of the applicator have a distribution that permits the pick up of an adequate supply of material and retains it until it is applied to the eyelashes. It is also important that the filaments that form the bristle ends have sufficient structural strength to comb the material or mascara through the eyelashes.
- a conventional mascara brush has a twisted wire core, and a bristle portion.
- the bristle portion has a plurality of plastic filaments. Each plastic filament is gripped by the twisted wire medially of its ends to form bristle ends.
- U.S. Patent No. 4,887,622 to Gueret is directed to a brush of this type in which the bristle ends extend radially from the core as a helical array and are disposed in a manner to avoid interference of the bristle ends of one turn with the bristle ends of adjacent turns.
- Each filament has a diameter from 0.10 to 0.25 mm.
- the number of filaments per helical turn of the twisted wire core is approximately 10 to 40.
- U.S. Patent No. 4,993,440 to Gueret is also directed to a mascara brush that has a twisted wire core, and a bristle portion.
- the bristle portion has a plurality of plastic filaments.
- Each plastic filament is gripped by the twisted wire medially of its ends to form bristle ends.
- This patent also provides that each filament has one or more U or V shaped capillary channels formed in its surface. The sides of the U or V shaped capillary channel converge slightly toward each other near their free ends before again diverging outward to a zone where the channel opens out at the surface of the filament.
- the bristle ends are disposed to extend radially from the wire core, and are distributed to avoid interference of the bristle ends of one turn with the bristle ends of adjacent turns.
- U.S. Patent No. 4,733,425 to Hartel, et al. is directed to a brush of the type described above in U.S. Patent No. 4,887,622.

- the filament is described as a hollow or tubular polyamide, or one that has a non-circular cross section.
- an applicator that has a core of twisted wire that forms a plurality of helical turns.
- the applicator includes a bristle portion that is formed of a plurality of filaments with each filament being crimped medially of its ends by the wire core.
- the ends of the crimped filament form bristles or bristle ends that flare outwardly in various directions from the core. This flaring forms a uniform distribution of the bristle ends throughout the bristle portion.
- the filament density in the bristle portion is approximately 45 to approximately 60 filaments per helical turn.
- Each filament has a central core with at least two spaced apart radially extending flanges.
- at least one of the flanges is bent.
- at least one of the flanges radially extends from the central core in a nonlinear manner.
- the central core is hollow. The area along the central core between adjacent flanges holds mascara by surface tension.
