Convertible peristaltic and piston pump dispenser

A dispenser for flowable materials comprising:

• a replaceable piston pump reservoir unit comprising a reservoir for flowable material and a piston pump, the piston pump including a piston chamber-forming member coupled to the reservoir and forming a piston chamber in communication with material in the reservoir, the piston pump including a piston element reciprocally slidably received in piston chamber-forming member for movement between a retracted position and an extended position to dispense material from the reservoir out a piston pump outlet on the piston element,
• a replaceable peristaltic pump reservoir unit comprising a reservoir for flowable material and a deformable tube member in communication with material in the reservoir providing a peristaltic pump outlet to dispense material from the reservoir,
• a housing;
• the housing including both a piston pump socket arrangement adapted to removably engage the piston pump reservoir unit for dispensing material from the piston pump reservoir unit and a peristaltic pump socket arrangement adapted to removably engage the pump reservoir unit for dispensing material from the peristaltic pump reservoir unit;
• the piston pump socket arrangement including a piston carriage member mounted to the housing for relative movement between a first position and a second position;
• the piston carriage adapted to removably engage the piston element;
• an actuator member mounted to the housing for relative movement between a retracted position and an extended position;
• the piston carriage member and actuator member coupled such that movement of the actuator member between the retracted position and the extended position correspondingly moves the piston carriage member between the first position and the second position;
• the peristaltic pump socket arrangement having a first block member and a second block member removably receiving the deformable tube there between, the first block member and the second block mounted to the housing for movement towards and away from each other between a distant first position and a proximate second position to compress the deformable tube and dispense material from an outlet distal end of the deformable tube;
• the first block member and actuator member coupled such that movement of the actuator member between the retracted position and the extended position correspondingly moves the first member between the first position and the second position.
