Abstract
A rotary dispenser with internal pressure relief includes a housing; an elevator slidably and non-rotatably disposed in the housing; a dome slidably and rotatably mounted relative to the housing and having at least one aperture for dispensing product from within the housing; a drive member fixed relative to the dome and rotatably engaged with the elevator whereby rotation of the drive member relative to the elevator slides the elevator relative to the housing; and a pressure relief member including a cam and a cam follower, one of the cam and the cam follower being associated with the dome and the other of the cam and the cam follower being associated with the housing, the cam follower being rotatably engaged with the cam whereby rotation of the housing relative to the dome rotates one of the cam and the cam follower relative to the other of the cam and the cam follower, the cam having at least one first cam surface for causing axial movement of the dome toward the elevator and at least one second cam surface for allowing axial movement of the dome away from the elevator.
