Title: APPLICATOR ATTACHMENT TO CONVERT OSCILLATING ROTATIONAL MOTION TO ORTHOGONAL RECIPROCATING MOTION
Abstract:
An infuser tip can be used to assist penetration of cosmetic formulas through the outer layer of human skin. Generally described, the infuser tip includes a concave surface or a similarly structured area that retains formula to generally apply cosmetic formula to the skin with a reciprocating (e.g., tapping) motion. Embodiments of converter assemblies for generating such reciprocating motion from an oscillating motor include an outer housing, a follower having a cam following surface, and a cam rotatably couplable to the outer housing; or a follower elastically coupled to the outer housing, and a contact point configured to slidingly interface a following surface on the follower. In general, the follower is configured for reciprocating motion and the cam or contact point are configured for oscillating motion, both with respect to the outer housing. Interaction of the cam or the contact point and the following surface causes the follower to reciprocate.
