In the upper part of the container there is provided a filling orifice (6). To simplify the use of the apparatus and to prevent mistakes, the orifice (6) is provided with a closure means (27) which is arranged to close the orifice automatically in conjunction with charging gas to the container (4). In this respect, the closing movement of the closing means is preferably arranged to be initiated by the stream of gas entering the container.
