Abstract
The closure of the bottle is achieved with the aid of a cylindrical ring (20), the base of which is closed by a membrane (22). This ring (20) is put in place together with a filling adaptor which is screwed onto the neck of the bottle and which allows the ring (20) to be tightened after filling. A drawing-off adaptor is also designed to be screwed onto the neck of the bottle and includes a bevelled drawing-off tube intended to pierce the membrane.
