Abstract

A dispensing head is removably attached to a beverage dispensing system base without additional fasteners, wherein beverage forming liquids are supplied through a plurality of separate conduits in the base. Each base conduit has a normally closed valve that normally blocks fluid flow. The dispensing head has at least one passageway that receives liquid from an associated one of the base conduits. A projection associated with each dispensing head passageway opens the associated conduit valve to allow fluid flow from the base to the head. Dispensing valves in the dispensing head are independently accountable to regulate the dispensing of the beverage. In one version of the invention, four liquids are supplied to the dispensing head through the conduits, namely two liquid concentrates; carbonated water; and noncarbonated water. By selective opening of the dispensing valves, a plurality of beverages are formed from combinations of one or more of the liquids.
