ABSTRACT:
An arrangement for closing an open end of a substantially stiff, generally cylindrical side wall of a container is disclosed, comprising a cover of an elastic, resilient material to be fixed to an end portion of the side wall. Said cover includes a central main portion forming an end wall of the container and an integral peripheral flange projecting in an axially outward direction from said main portion. A hard spring, formed by a ring of circumferentially closed configuration, is pressed into the cover, on the inner side of said flange, and into engagement with a selected circumferentially extending section of the flange to force the outer side of said flange section into contact under pressure with the inner side of the end portion of the side wall. Hereby a tight connection is established between the cover and the side wall and the cover is firmly fixed to the side wall.
