Abstract: A box having side walls (10, 12, 14, 16), a first set of panels (20, 22, 24, 26) along the top edges of the side walls and a second set of panels (28, 30, 32, 34) along the bottom edges of the side walls. The first set of panels overlap one another to form a box top and the second set of panels similarly overlap to form a box base. The first set of panels are so shaped that the box top has some areas which are above the level of the remainder of the top. The panels forming the box base also provide areas which are above the level of the remainder of the base. Said areas of the top and base are of the same shape and layout so that when two boxes are stacked, said areas of the top are received in said areas of the base.

Abstract: A container for perishables such as fruit is disclosed. The container includes a tray having a base panel and upstanding side and end panels. At each end there are locking panels which are parallel to, and spaced inwardly from, the end panels. Between each end panel and the two adjacent locking panels there is a strengthening insert of wood, metal or synthetic plastics material. An end piece of inverted U-shape is provided to hold each composite end wall comprising a strengthening insert, an end panel and two locking panels in its erected condition. The spaced walls of the insert are located one on each side of the composite wall. Tongues (or right angled corner structures) project upwardly from the end pieces. Where tongues are provided, the base panel can have apertures therein for receiving the tongues of a lower container. Where right angled corner structures are provided, an upper container nests within the four structures of a lower container.
