Abstract
A manually actuated pump dispenser has a control ring mounted on the pump body for rotation about its central axis and engaging the pump plunger for controlling the number of plunger strokes and thereby the dosage of the dispenser for each cycle of revolution of the control ring, the plunger being releasably locked with the control ring against plunger reciprocation at the commencement and at the end of each cycle of revolution of the control ring to thereby render the same child-resistant.
