At least one protuberance, which can be inflexible, can project from a shoulder portion of the innerbody and can be axially aligned with a flexible wall segment of the spiral member thereby to produce a frictional drag between the innerbody and the spiral member. The flexible wall segment of the spiral member can comprise a proximally disposed skirt. Axial movement of the elevator member can be produced by opposed lugs that project from the elevator member through opposed longitudinal tracks in the innerbody and into engagement with opposed spiral threads on the spiral member.

  • Patent number: 5997202
    Abstract: A package for a solid stick product, including barrel for containing the stick product and, provided within the barrel, a product support member for supporting the stick product thereon. The product support member is movable in the longitudinal direction of the barrel for raising and lowering the stick product. The barrel has a longitudinally extending slot through a wall thereof. An adjustment button is provided on the outside of the barrel and is movable in the longitudinal direction of the barrel generally over the slot area. A tab extends through the slot and connects the adjustment button to the product support member, whereby movement of the adjustment button outside the barrel brings about an equivalent translational movement of the product support member and, therefore, the stick product within the barrel. Thus, by raising or lowering the adjustment button outside the barrel, the user can raise or lower the stick product to extract the product from or retract the product within the barrel.
