In a sheet metal or plastic container for storing beverages or the like a plug member is located against an opening region provided in the container's end wall and defined by a score line. The plug member has a closing peripheral edge which has the same geometry as the peripheral edge of the opening resulted after the score line is ruptured by external pressure applied to the plug member towards the interior of the container. The plug member and the opening region after it has been ruptured are slidably displaced from the opening to expose the latter. That opening can be tightly closed again by the plug member inserted at that peripheral edge into the opening.
