An end cap for a container is generally dish shaped and is for fitting within a tubular container to be fixed in position at one end thereof or for sliding movement within the container as the container is emptied. The end cap includes a peripheral portion 129 which is capable of limited movement relative to the main portion of the end cap so as to allow movement of the end cap in one direction within the container but to cause locking of the end cap against the wall of the container when the end cap is caused to move in the opposite direction. |
