ABSTRACT:
There is disclosed a system and dispensing unit for the controlled and metered dispensing of a liquid product, or of two or more liquid products, which should be combined in the right proportions only shortly before ultimate usage. The basic system, as disclosed, employs a single pressure source for pressurization of the liquid product and the pressurized dispensing of the liquid product from the dispensing unit, per se. In addition to the basic illustrated system, there are disclosed novel dispensing units which enables the dispensing of a uniform or proportioned amount of liquid upon each operation thereof. Further, these units are constructed so as to permit the dispensing of several different liquids simultaneously from the same unit, or the selected dispensing of the individual liquid.
