Bladder-operated dispenser

摘要

A bladder assembly for operating a dispenser for fluid material. The dispenser includes a hinged pressure bar movable into and out of collapsing engagement with a collapsible tube which leads from a source of supply of the material to be dispensed. The bladder assembly includes a flexible bladder in fluid communication with a foot pump. The bladder is removably located within the dispenser behind the pressure bar so that inflation of the bladder by pumping air into it through a hose from the foot pump moves the pressure bar into collapsing engagement with the tube to dispense the material.
