  • Patent number: 4938387
    Abstract: A device for selectively dispensing and mixing a plurality of beverages, having separately for each beverage a storage unit a pump unit and a dispensing unit, the units for each beverage are connected in series by pipe conduits, the dispensing units being combined to a bundle to dispense and mix the beverages in selected quantities and combinations in a receptacle, such as a drinking-glass, in order to prevent admittance of air both into the storage units and the dispensing units, and to prevent after-dripping and incorrect dispensing. Each storage unit comprises an intermediate storage unit provided between a storage container and a respective pump unit and arranged to receive a volume of beverage larger than the volume dispensable on each operation by the pump unit via the dispensing unit. Each dispensing unit comprises a dispensing nozzle of resilient material and actuable by the pressure from the pump unit only.
