ABSTRACT:
An applicator for the application of a cosmetic medium, such as mascara, is disclosed having a central core, preferably formed from a twisted metal wire, having a brush section at one end thereof. The brush section comprises a plurality of radially extending bristles gripped medially by the central core. At least some of the bristles have a substantially slotted cross-sectional configuration, most preferably, each bristle is substantially hollow and has a slot extending along at least a portion of the length of the bristle. The cross-sectional configuration of the slotted filaments is such that the gripping thereof by the core causes the slotted filaments to flare outwardly in a generally random direction and so as to be substantially uniformly distributed throughout the brush section; unlike the prior art bristles, the bristles of the present invention do not follow a substantially helical pattern when gripped by the twisted wire core. Various types of slotted filaments are disclosed including a rectangular type (having four sidewalls) and triangular type (having three sidewalls). In each type, the slot is open along at least a portion of one sidewall.
