ABSTRACT:
A receptacle for liquids, which has a portion with an opening and provided with a thread portion and a lid with a thread portion for engagement with the first said thread portion and a drawing off tube. This tube is displaceable between two positions, in one of which it extends from the opening portion into the interior of the receptacle. In the other position the tube extends from the opening portion and outwardly which is utilized in connection with drawing-off operations. The tube has a flange which is arranged in a resilient manner to change shape. It can be squeezed between an inner sealing surface of the lid and a sealing surface of the opening portion of the receptacle for liquids. Over a limited extension in connection with the removal of said surface of the lid from the sealing surface the flange can be pressed against said surface of the lid performing a sealing action and at the same time be removed from the sealing surface of the opening portion, thereby uncovering escape openings round the tube for gas under pressure.
