The parts (40-43) of the box which form a rectangular base are connected along their edges to side wall parts (10-13) that are pivotally connected to each other in order to form a tube with a rectangular cross- section. Each base part is joined to a side wall part and folded against the inside of the latter when the box is collapsed. Adjacent base parts are overlapping and joined together in such a way that a flat base is formed. The base parts protrude from the top side of the base along a diagonal (70) in the base. |
