ABSTRACT:
A dispenser for a viscous substance includes a disposable plastic container for the substance and a pump permanently unreleasably mounted to the top of the container for pumping the substance from the container. The pump includes a housing communicating with the interior of the container and a pumping assembly including a movable housing wall and a tubular member connected to the wall and being movable along a motion axis between extended and retracted positions relative to the housing. An actuator is provided for the pump which includes a support member removably mounted to the cartridge, a target member movably mounted to the support member and linkage for releasably linking the target member to the tubular member so that when the target member is moved in one direction, the pumping assembly is moved to its extended position in the housing and when the target member is moved in another direction, the pumping assembly is moved to its retracted position in the housing. Preferably, the connection between the tubular member and the movable housing wall is a lost-motion connection.
