Abstract
A pump dispenser, useful especially for lotions, soaps and creams, has a structure which allows locking into a sealed and locked position. The pump dispenser may therefore be transported and stored without fear of accidental actuation or leakage. The dispenser has a valve stem which acts as an inlet valve, as well as a mechanism for sealing the inlet and outlet to the pump chamber when locked. The pump dispenser also has structure to seal the vent passage when in a locked position.
