ABSTRACT:
A fluid dispenser10with a replaceable receptacle11containing fluid47positioned within a housing12. An inlet tube42and an outlet tube43are connected to a pump assembly15for drawing fluid from the receptacle and moving the fluid through a nozzle80having fluid discharge aperture41. The nozzle is secured to a hand actuatable cover13which is depressable to operate the pump. The pump is mounted upon a retainer14which is connectable to the housing. When the receptacle becomes empty, the retainer may be disengaged from the housing, and the retainer and pump are then lifted away as one unit from the housing. The empty receptacle may then be replaced with a full one, and in reverse order, the dispenser may be reassembled.
