Abstract: A dispensing device particularly useful for dispensing nutritional liquids includes an electrolytic cell having electrodes and an electrolyte capable of generating a gas upon the energization of the electrodes, which gas causes the dispensing of the liquid according to the rate of generation of the gas. The container for the liquid to be dispensed may be a disposable unit including the electrolytic cell, and a non-disposable electrical control circuit may be provided for controlling the rate of energization of the electrodes. The dispensing unit may also include an outer container adapted to receive a bag containing the liquid to be dispensed, the generated gas being applied between the outer container and the pliable bag.
