用于涂抹睫毛膏等化妆品，通过旋转振荡提升效果。
专利摘要
一种用于将化妆品（如睫毛膏）涂抹到睫毛的装置，包括手柄、杆以及耦合到杆并相对于手柄可旋转地支撑的涂抹器头。致动器使涂抹器头以旋转振荡运动移动，其中涂抹器头响应于致动器的操作而自动沿第一旋转方向和第二旋转方向旋转。附加地或替代地，致动器还可使涂抹器头径向平移、使涂抹器头旋转小于360度的角度、以及改变涂抹器头的旋转速度。涂抹器头可包括在旋转期间间隔开以限定间隙的突出物，从而促进睫毛的覆盖和分离。
Original abstractAn 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.
