ABSTRACT:
A relatively small product dispenser for cosmetics such as creams and lotions and adapted to be carried in a handbag or purse has a locking ring which is rotatable to a first orientation that prevents depression of an actuator and which is also rotatable a second orientation enabling actuator movement. The locking ring is coupled to a closure element in such a fashion that the element covers a discharge opening of the dispenser when the actuator is locked in position in order to retard the drying and consequent hardening of any products remaining within a passageway adjacent the discharge opening. As the locking ring is turned to its second orientation enabling the actuator to be depressed, the closure element moves away from the discharge opening to permit full flow of products therethrough.
