  • Fluid dispensing mechanism
    Patent number: 5878919
    Abstract: A product dispenser utilizes an elastomeric tube which is compressed between a plunger and a frame by means of axially slidable members which support the plunger and frame for movement in equal and opposite directions so as to compress the tube and thereby force an aliquot portion of liquid from the tube. Release of the tube will cause the tube to return to its original position due to the elasticity of the tube.
