Patent ID: 7175358

Claim:
A cosmetic applicator, comprising: a. an internal cylindrical casing having an exterior wall having a top and a bottom with a recess in the exterior wall adjacent the location of the bottom, the exterior wall having an interior surface defining an interior chamber, the interior surface having a pair of oppositely disposed longitudinal channels extending from adjacent the bottom of the casing to an area between the top and bottom of the casing and terminating at an interior transverse wall; b. a cylindrical shaft having an exterior cylindrical wall with a multiplicity of spaced apart parallel threads formed at an angle on the exterior cylindrical wall, the cylindrical shaft having a top and a bottom, a base having an exterior wall and a bottom which form an interior cavity into which the bottom of the cylindrical shaft is affixed with a space in the interior cavity around the bottom of the cylindrical shaft, the base having grasping means on its exterior wall; c. a hollow cylindrical shelf having an exterior wall with a top and bottom, the top of the exterior wall terminating in a top platform with a top circumferential wall extending from the top platform to form a top cavity with a pair of cosmetic grasping means formed on the top platform and extending into the top cavity, a pair of oppositely disposed teeth extending transversely from the exterior wall, the exterior wall having an interior surface defining an interior cavity which is open at the bottom and a pair of oppositely disposed interior teeth adjacent the bottom of the interior surface and extending transversely from the interior surface into the cavity; d. the cylindrical shaft and the hollow cylindrical shelf received within the interior chamber of the internal cylindrical casing with the recess in the lower area of the exterior wall of the internal cylindrical casing retained within the hollow cavity of the base and surrounding the cylindrical shaft; and e. the cylindrical shaft being positioned within the hollow interior cavity of the hollow cylindrical shelf so that the threads of the cylindrical shaft intermesh with the oppositely disposed interior teeth of the hollow cylindrical shelf so that as the grasping means causes the base to rotate, the interior teeth ride on the threads and when the cylindrical shaft is rotated in one direction the teeth rotate upwardly on the threads and cause the hollow cylindrical shelf to move upwardly within internal cylindrical casing and when the grasping means is rotated in the opposite direction the teeth ride downwardly on threads and cause the hollow cylindrical shelf to move downwardly within interior cylindrical casing, each respective exterior tooth on the hollow cylindrical shelf respectively received within a longitudinal channel in the interior wall of the internal cylindrical casing to prevent the hollow cylindrical shelf from rotating or spinning so it only moves up and down within interior cylindrical casing.
