ABSTRACT:
A fountain-style carbonated soft drink dispenser includes a housing adapted to attach to a beverage container, an actuator for selectively opening a fluid conduit, and one or more long tubes that vary a pressure drop across the dispensing assembly and convey fluid. The resistance through the tube(s) is decreased as the pressure within the container decreases so as to maintain a substantially constant flow rate throughout dispensing.
