Child safe cream dispenser
摘要:
The child safe cream dispenser is a child-resistant pump-actuated dispenser for topical preparations having an elongated housing, the housing defining a container for holding a supply of cream or other viscous material. A plunger mechanism functions to advance a piston through a one-way ratchet or clutch mechanism so that successive operation of the plunger mechanism causes the piston to advance towards a dispensing opening. A trigger release mechanism disables the plunger mechanism until a release button has cleared the sidewall of the housing. The dispensing outlet may have a cap or a ball valve that is either pivoted or rotated to an open position by operation of the plunger trigger.
