  • Patent number: 4450987
    Abstract: A portion control liquid dispenser comprising a conductive metal liner forming the inner surface of a container or tank, an intermediate layer of insulation and an outer shell. The inner tank surface is cooled by a thermoeletric heat pump. A removable liquid container is placed within the tank so that its walls make contact with the cooled inner liner. The container is open at the top for liquid fill and venting and is coupled at its lower end to a molded element comprising a dispensing tube combination cap. The elongated dispensing tube extends downwardly within a locating structure and houses a plunger having a conical lower portion which normally blocks an aperture in the lower end of the tube. A solenoid coil is mounted about the downwardly extending tube and is activated by a selected manual switch to dispense a particular amount of liquid.
