A multiwalled container made of corrugated paper board and formed from an open ended sleeve of such multiwalled container board is provided with an end closure that is discreet from the sleeve but is connected thereto via flaps connected to the outer surface of the walls of the sleeve. The closure includes at least one panel connected to the sleeve by the flaps and providing a bridging member extending across the open end of the sleeve and functioning to resist outward deflection of the side walls of the sleeve via tension in the bridging member when said container is erected and foldable into the interior of said sleeve when said container is in knock down condition.
