Cosmetic applicator
First Claim
1. A mascara applicator comprising:
- a handle;
a stem defining a longitudinal stem axis and having a first end coupled to the handle and a second end;
a mascara applicator head coupled to the stem second end and supported for rotation about the longitudinal stem axis;
an actuator operatively coupled to the applicator head for moving the applicator head in a rotational oscillating motion; and
a controller operatively coupled to the actuator for automatically reversing the applicator head direction of rotation, wherein the applicator head automatically alternates between a first rotational direction and a second rotational direction in response to operation of the actuator;
wherein the controller provides a dynamic speed signal to the actuator to automatically adjust the rotational speed of the applicator head; and
wherein the applicator head is rotatable at speeds of 1 to 200 rpm.

Abstract
An apparatus for applying a cosmetic, such as mascara to eyelashes, includes a handle, a stem, and an applicator head coupled to the stem and supported for rotation relative to the handle. An actuator moves the applicator head in a rotational oscillating motion, in which the applicator head automatically rotates in both a first rotational direction and a second rotational direction in response to operation of the actuator. Additionally or alternatively, the actuator may also radially translate the applicator head, move the applicator head through an angle of rotation less than 360 degrees, and vary the rotational speed of the applicator head. The applicator head may include protrusions that are spaced to define gaps during rotation, thereby to promote coverage and separation of eyelashes.
