The device (1) has a valve (4) rigidly connected to a liquid container (3), and a sleeve (19) whose upper part is connected to the valve and lower part is inserted into a bottle. A contracting zone of a liquid flow path (12) is formed between a liquid inlet and a liquid outlet, and exhibits a cross-section smaller than that of the outlet such that air takes a reverse path of the liquid during an operational configuration of the device. The lower part is laterally sealed against air. An opening is formed at an end of the lower part to allow outflow of the liquid and inflow of the air. |
