    • A personal care applicator (20; 200; 400) has a platform (40) mounted for movement within a barrel. A screw member (42; 204; 404) has: a screw (44) extending into an aperture of the platform so that rotation of the screw about an axis (500) causes a shift of the platform and screw relative to the barrel parallel to the axis. One of the barrel and the screw member has a track (62; 124; 126; 126) circumscribing the axis and having a surface with an axial position varying with circumferential position about the axis. The other of the barrel and the screw member comprises a follower (124; 62; 144; 220) engaged to the track so that a continuous rotation of the screw member about the axis causes a reciprocal motion of the screw relative to the barrel. The track is shaped to provide two cycles of the reciprocal motion per each revolution of the screw member.
    • 个人护理施加器(20; 200; 400)具有安装用于在筒内移动的平台(40)。 螺钉构件(42; 204; 404)具有:螺钉(44),其延伸到平台的孔中,使得螺钉围绕轴线(500)的旋转引起平台和螺钉相对于桶平行于 轴。 其中一个筒体和螺杆构件具有外接轴线的轨道(62; 124; 126; 126),并具有轴向位置随着围绕轴线的圆周位置而变化的表面。 筒体和螺杆构件中的另一个包括接合到轨道的从动件(124; 62; 144; 220),使得螺杆构件围绕轴线的连续旋转引起螺杆相对于筒体的往复运动。 轨道成形为螺杆构件每次旋转提供两个周期的往复运动。
