Abstract
Abstract A container is provided with a lid which projects outwardly beyond the walls of the container and with a flange secured on the outside of the container slightly below its top. Bolts are provided passing through the projecting portion of the lid and the flange for drawing the two towards each other. Immediately outside the wall of the container is an annular washer of plastic material arranged in the space between the lid and the flange. A resilient support strip which is slightly less in height than the distance between the flange and the lid is positioned in the space between the washer and the bolts and abuts with one edge against the outside of the washer and with the other edge against the bolts.
