  • Patent number: 5984552
    Abstract: "Lock" for this impel/repel lipstick container comprises a downward extension at the lower end of the slot in the inner body. The extension is adapted to receive the pomade cup lug and is partly defined by a margin portion facing in opposition to the direction in which the lug is moved when the cam is turned to raise the cup. When a user attempts to propel the pomade upward by turning the cam relative to the inner body, the cam track merely forces the lug against the margin portion of the extension. To unlock, the salesperson applies a tool upward into the base of the lipstick container to raise the pomade cup so that the lug moves upward out of the extension.

  • Patent number: 5863144
    Abstract: A lipstick container cover has a cup-shaped insert which sealingly telescopes over a sealed base assembly. The cover insert has an inward peripheral rib which makes line sealing contact with the sleeve. A bump formed on the sleeve raises the rib to vent pressure caused either by pushing the cover on the lipstick container or pressure build-up due to vaporizing solvent after the cover is fully installed. Venting the pressure in the container avoids the lifting off of the cover after installation. Otherwise such lifting unseals the container.

  • Patent number: 5649777
    Abstract: A cosmetic preparation dispenser permits filling of a dispenser cartridge and retraction thereof, but is subsequently inoperable until assembly with a master case. The cartridge includes a cam sleeve, innerbody and elevator cup. The locking of the cartridge is obtained by lower leftwardly extending track segments at the lower end of innerbody longitudinal track segments, which trap and retain the elevator cup when it is retracted after the cartridge is filled with a cosmetic stick. When the cartridge is assembled with the master base, a stem in the master base pushes against the elevator cup to urge it out of it locked position to permit the elevator cup to be freely movable along the axial path.

  • Patent number: 5638839
    Abstract: A refillable cosmetic case has a base with a recess for a releasable tray held in place by a tray retaining cover hinged in the base and having a latching element. The case lid has a rear edge and is hinged to the base at an edge opposite the tray cover hinge, and the lid rear edge can be associated with the tray to assist in its removal whereby when the lid is opened beyond its usual limit of travel the rear edge releases the latching element and thus the tray retaining cover. The cover pivots back on its hinge, so the tray can be lifted out and refilled or replaced.

  • Patent number: 5636930
    Abstract: A cosmetic preparation dispenser is provided that has a helical cam track with a horizontal step at its lower end and a longitudinal innerbody track that terminates adjacent the horizontal step. A cam follower lug of an elevator cup will track into and be trapped by and between the horizontal step and the lower end of the longitudinal track. This locks the innerbody to the cam sleeve to prevent longitudinal sliding of the innerbody relative to the cam sleeve when, e.g., a lipstick cover is removed in an assembled cosmetic container, which cover removal might leave an undesirable gap between the decorative shells surrounding the innerbody and cam sleeve.

  • Patent number: 5324126
    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.
