The closing device for a bottle containing a liquid comprises a casing (1) with a plastic cylindrical body (2) disposed therein, a dispensing device (5) with inlet and outlet openings, a cap (6) rigidly fastened in the cylindrical body (2), and a stopper (7) with an upper end surface (20), upper and lower cylindrical mounting surfaces (8 and 9 respectively), and upper and lower annular supporting surfaces (10 and 11 respectively). The upper annular supporting surface (10) of the stopper (7) is provided with locking teeth (17) to prevent the dispensing device (5) from being turned relative to the stopper (7) and is contiguous with corresponding congruously arranged stopping members (18) in the cavity of the dispensing device (5). The lower annular supporting surface (11) of the stopper (7) is provided with locking catches (19) to prevent the stopper (7) from being turned relative to the neck of the bottle (13). The assembly for closing a bottle also comprises the neck of the bottle (13), which has at least one annular rib (36) on the lateral portion thereof and an end face which abuts the lower annular supporting surface (11) of the stopper (7). Furthermore, stopping ribs (37) are arranged at given intervals on the end face of the neck of the bottle (13) in order to engage with the locking catches (19) on the lower annular supporting surface (11) of the stopper (7). This makes it possible to provide highly reliable closure of the bottle and prevent the closing device from being turned relative to the neck of the bottle, while also reducing the amount of material required to produce the bottle closing assembly. |
