Patent ID: 8074666

Claim:
A head-switchable cosmetic applicator, comprising: a head assembly including a ferrule having: (a) a first generally planar mating surface formed at least in part by a first magnetic element and (b) one of a recess or a projection; and a handle including: (a) a second generally planar mating surface formed at least in part by a second magnetic element and (b) the other of the recess or the projection; wherein the recess is non-magnetic and capable of receiving the projection; wherein at least one of the first and second magnetic elements is a magnet, and the head assembly is releasably attachable to the handle by magnetic attraction between the first and second magnetic elements creating a pulling force between about 0.4 lbf to about 1.2 lbf when the head assembly and the handle are attached; and wherein the part of the first generally planar mating surface formed by the first magnetic element and the part of the second generally planar mating surface formed by the second magnetic element are in flush alignment when the head assembly and the handle are attached; wherein the projection and the recess have longitudinal axes that align when the head assembly and the handle are attached, wherein one of the projection and the recess comprises at least one axially extending groove, and wherein the other of the projection and the recess comprises at least one protuberance positioned to engage in the at least one groove to restrain the head assembly from rotation relative to the handle about the aligned axes.
