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.

In a product dispenser having a body with walls defining a product holding chamber and a piston reciprocably movable along a reference axis within said chamber for pumping products from the latter, the improvement comprising: a depressible actuator connected to said piston for movement of the piston along said axis, said actuator including structure defining a passageway therethrough and in communication with said chamber for receiving the flow of products from said chamber upon movement of said piston, said structure terminating in a product discharge opening communicating with said passageway; a closure element carried by said actuator and movable between a first position substantially closing the discharge opening and a second position away from said first position for enabling the flow of products through said opening; and a locking member rotatable relative to said actuator between a first orientation and a second orientation, said locking member being coupled to said closure element for moving said closure element toward said first position as said locking member is moved toward said first orientation and for moving said closure element toward said second position as said locking member is moved toward said second orientation, said locking member including means for preventing depression of said actuator and thereby movement of said piston when said locking member is in said first orientation and said closure element is in said first position substantially closing said discharge opening, said locking member being movable in an arc substantially about said axis of movement of said piston during movement between said first orientation and said second orientation.
