ABSTRACT:
An improved end closure arrangement for a paperboard container which, when moved to closed position, will remain in a closed position without springing back to an open position. The closure arrangement includes a pair of outer end closure flaps interconnected by a pair of inner bellows members each of which includes three panel elements. The panel elements are foldably joined to a container end wall and to each other along spaced fold lines and are separated from each other by U-shaped cut lines that enable the container closure flaps, when folded to a closed position, to remain in a closed position without springing back to open position.
