Portable post-mix beverage dispenser unit

摘要

A lightweight, portable post-mix carbonated beverage dispenser unit for use in small offices or small-volume locations is described. Flavored syrup is supplied to the unit from disposable sealed syrup packages which are plugged into a dispenser valving system. CO2 is supplied to the unit carbonator system in returnable containers which also may be quickly plugged into a CO2 valving system. A thermoelectric refrigeration system may be provided to decrease noise and the number of moving parts or a mechanical freon system may be used. The unit construction may be modular for ease of repair. The cabinet is injection-molded from plastic. Water is supplied to the unit for mixing with the CO2 and syrup from a water reservoir which may be manually filled. The refrigeration system cools the water in the reservoir, as well as the syrup packages and carbonator tank.
