ABSTRACT:
A portable beverage dispenser system particularly suited for dispensing semi-frozen slush beverages is housed within a back pack and transported on the back of a vendor. The slush beverage is contained in an insulated vessel having a sealed closure lid, a gas supply valve connected with a pressurized gas tank to maintain pressurization of the beverage, a slush delivery conduit with an insulated dispensing hose releasably connected to the conduit, and an agitator contained within the vessel which is rotated by a motor on the vessel exterior. The motor is selectively operated by a battery pack carried by the back pack to swirl the slush beverage adjacent the lower end of the delivery conduit and to prevent the semi-frozen slush beverage from solidifying as it is being discharged. The vessel is surrounded by a thermally insulating jacket which prevents the formation of a thin layer of ice on its exterior due to the temperature of the semi-frozen slush beverage contained therein. The slush beverage vessel including the motor and the pressurized gas supply tank including a recharging manifold assembly are carried in the back pack. In a preferred embodiment the central compartment may be divided by walls to define individual compartments for receiving the components. The side wall of the back pack may be provided with an opening through which the dispensing hose extends when in use.
