摘要

The dispenser consists of a support (2) for a casing (3) holding a supple container (5) filled with liquid and equipped with a tap (6). The casing, which also acts as a heat exchanger, contains a moving weight (51) or an inflatable chamber that applies a pressure on the container as the liquid is drawn from it. The weight can be removed from the casing after taking off its cover (42), while the inflatable chamber is connected to a pressurised gas source such as a pump or compressor.
