  • Patent number: 4946072
    Abstract: An apparatus is disclosed which dispenses a metered quantity of a liquid. The apparatus uses a roller and base pad to form a nip which receives a dispensing leg of a container. Movement of the roller along the base pad causes liquid within the dispensing leg to be dispensed through a pressure responsive valve. The roller travels along a D-shaped path, the straight portion of the path is the nip forming portion. The apparatus operates in response to an object reflecting a beam of electromagnetic energy in the form of infrared light. A container is also disclosed which has a housing, preferably cardboard, and an envelope of flexible plastic contained therein. The envelope holds the liquid and the dispensing leg is accessed through a tear-away opening in the cardboard housing.
