Abstract
A cosmetic preparation dispenser is provided that has a resilient tab formed on the lower end of the innerbody that presses against the cam sleeve to provide a desirable swivel drag, and which tab is prevented from undesirable deformation that reduces the swivel torque by providing a relaxation zone in the cam sleeve where the tab can recall its original shape. The relaxation zone is preferably a thin walled section of the cam sleeve that is formed by the combination of a flat outer wall and a circular inner wall, which thin walled section is deformable by pressure from the tab when the tab is seated against the thin walled section. The tab presses against the cam sleeve which causes the cam sleeve to move up a bevelled shoulder to enhance swivel drag between the cam sleeve and a retaining lip on the innerbody. The bevelled shoulder also engages the cam sleeve when force is applied to the elevator.
