Cosmetic applicator
First Claim
1. Apparatus for applying mascara to eyelashes, comprising:
- a handle;
a boss coupled to the handle;
a stem defining a longitudinal stem axis and having a first end coupled to the handle and a second end, wherein the stem first end comprises a stem extension defining a socket sized to rotatably engage the boss;
an applicator head coupled to the stem second end; and
an actuator operatively coupled to the applicator head for moving the applicator head in a vibrational motion, wherein the vibrational motion comprises a frequency of 0.5 Hz to less than 9.5 Hz, wherein the actuator comprises an electric motor having a rotating motor shaft and an eccentric weight coupled to the motor shaft, and wherein rotation of the eccentric weight generates a vibratory force;
wherein the applicator head is supported for rotation with respect to the handle, andwherein rotation of the eccentric weight moves the applicator head in a composite motion including a vibrational component and a rotational component.

Abstract
An apparatus for applying a cosmetic, such as mascara to eyelashes, includes a handle, a boss coupled to the handle, and a stem defining a longitudinal stem axis and having a first end coupled to the handle and a second end, wherein the stem first end comprises a stem extension defining a socket sized to rotatably engage the boss. The apparatus further comprises an applicator head coupled to the stem. An actuator is operatively coupled to the applicator head for moving the applicator head in a vibrational motion. The actuator comprises an electric motor having a rotating motor shaft and an eccentric weight coupled to the motor shaft. Rotation of the eccentric weight generates a vibratory force.

10. A mascara applicator capable of producing a composite vibrational and rotational motion, comprising:
-
a handle with a motor coupled thereto through a spring, wherein the motor comprises a rotating motor shaft and an eccentric weight coupled to the motor shaft; a boss coupled to the handle; a stem defining a longitudinal stem axis and having a first end coupled to the handle and a second end, wherein the stem first end comprises a stem extension defining a socket sized to rotatably engage the boss; and an applicator head coupled to the stem second end; wherein rotation of the eccentric weight generates a vibratory force that is substantially isolated from the handle by the spring, and wherein the force is transferred via the boss to the stem, which causes the stem to rotate, which enables the applicator head to move in a composite motion comprising both a vibrational element and a rotational element. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
