Abstract:
1. An applicator for applying a cosmetic composition to eyelashes or eyebrows, the applicator comprising: a stem having a distal stem portion extending along a longitudinal axis; and a brush extending from the distal stem portion, the brush comprising a core supporting bristles, the core extending along a longitudinal axis that is entirely contained within a single plane and having a first curve that is concave towards a first side of the core and having a second curve that is concave towards a second side of the core opposite from the first side of the core, the first curve being different from the second curve, a distal end of the core being aligned with the longitudinal axis of the distal stem portion; wherein the longitudinal axis of the core crosses the longitudinal axis of the distal stem portion at least once; wherein the core of the brush extends along the longitudinal axis of the core towards a free end of the core without turning back towards the distal stem portion; wherein the first curve comprises a first vertex on the longitudinal axis of the core and the second curve comprises a second vertex on the longitudinal axis of the core, the first vertex being located on a first side of the longitudinal axis of the distal stem portion and the second vertex being located on a second side of the longitudinal axis of the distal stem portion opposite from the first side of the longitudinal axis of the distal stem portion; wherein free ends of the bristles of the brush define an envelope surface that is not circularly symmetrical about the longitudinal axis of the core, when the core is straightened, and which defines at least two faces oriented perpendicularly to the single plane containing the longitudinal axis of the core; wherein a first radius of curvature measured at the first vertex of the first curve is smaller than a second radius of curvature measured at the second vertex of the second curve and wherein the second radius of curvature differs from the first radius of curvature by at least 10%; and wherein the envelope surface is either conical or frustoconical along at least a fraction of the core, when the core is straightened.
