ABSTRACT:
A portable beverage dispenser for use by a vendor. The dispenser comprises a tank worn on the back of the vendor and having an insulated internal chamber for receiving a carbonated beverage to be dispensed by a pressurized gas in the chamber, a filling conduit for filling the chamber with the carbonated beverage, a pressurized gas supply for pressurizing the chamber, and an outlet nozzle. The chamber has a concave bottom wall with a small concave recess at its nadir. The conduit extends into the chamber at an acute angle to the chamber's longitudinal axis and has a port centered on that axis immediately adjacent the concave recess. The conduit carries carbonated beverage into the chamber so that the beverage enters the recess and quickly fills it with minimal foaming and so that the level of the beverage in the chamber is above the port to ensure that further filling of the chamber is also accomplished with minimal foaming. The supply of the pressurizing gas comprises a thermally insulative vessel holding a gas in a liquid phase for selective release to allow the liquified gas to change to its gaseous phase at a high pressure for introduction into the dispensing chamber to pressurize the dispensing chamber, whereupon a portion of the beverage is dispensed from the dispensing chamber via the nozzle.
