A means for emptying a container, especially a large bag (9), comprises a tubular element (1) having a cutter portion (2), a socket element (3), which is equipped with an outer thread (4), and at least one flange element (5). The means consisting of the parts (1,3,5) is pushed by using the cutter portion through the wall of the container (9), screwed into its final position and then locked by means of the flange portion (5), whereby the edge portion of the opening in the wall is wedged between the flange portion (5) and the thread (4). The tubular element is further provided with closing means (7), and may be withdrawn from the element (3) to which a cap is then fitted. <IMAGE> |
