ABSTRACT:
The dispenser for lip-salve or similar ointment includes a tube, an elevator axially movable within the tube for expelling the ointment, and a screw rotatable within the cylinder and interacting with the elevator for moving the elevator within the tube. The internal threads on the elevator interact with the external threads on the screw when the screw is rotated. The elevator is generally cup-shaped, and is arranged to prevent relative rotation between the elevator and the tube. A knob is integral with the screw and external of the tube, and a groove in the knob and a collar in the tube permit relative rotation of the knob and screw with the tube but prevents relative axial movement between the tube and the screw. At least one inclined plane is on the bottom of the cup-shaped elevator and interacts with at least one inclined plane on the knob, within the tube, whereby when turning the knob, the inclined planes on the knob forceably push the inclined planes on the elevator axially within the tube. The interacting external threads on the screw and the internal threads on the elevator move the elevator axially within the tube after the inclined planes on the elevator move out of contact with the inclined planes on the knob.
