The present invention relates to a beverage dispensing apparatus. Prior art devices are overly complicated and/or have the problem of undesirable oxygen contamination which destroys the product quality. The present invention provides improved pressurized dispensing of perishable beverages and liquids from a container which is isolated from the pressurizing atmosphere. The dispenser of the invention has a pump (24), an inflatable bag (28), a dispensing tube (40) and a dispensing nozzle (18). The inflatable bag and dispensing tube are sealably located in the container through its outlet. The pump, coupled to the bag through the container outlet, forces air into the inflatable bag causing it to apply pressure against the beverage within the container. When the dispensing nozzle which is connected to the dispensing tube is opened, the beverage is dispensed from the container by displacement as the bag expands. |
