A strong-box has side panels (4, 6) foldably hinged to a base panel (1). A lid (18) has an external depending flange (20) and internal depending support flanges (21). The top edges of the side panels have inturned flanges (10) which locate between the flanges (20 and 21) and which are engaged by locks (23) secured to the underside of a lid (18). When the box is folded down the lid (18) can be placed over the base portion and the locks (23) engaged with recessed projections (17) on the side panels (6). |
