<p>The invention concerns a liquid dispensing tap designed to be placed on a container with a single flow opening, such as a bottle with its neck pointing downwards, consisting of: a) two juxtaposed flexible tubes (2, 3); b) closure means (47) by squeezing the two tubes; c) plugging means (4, 56) for hermetically sealing the orifice around the two tubes when the tap is installed on the container. Moreover, one of the tubes (3) has locally in the proximity of its end (9) facing inside the container a reduced internal diameter. Preferably, the internal cross-section of each of the two tubes (2, 3) is of the order of 50 to 80 mm<2> and the reduced cross-section of the second tube (3) is of the order of 3 to 4 mm<2> over a height of 2 mm.</p> |
