Described is a collapsible folding box made from a one-piece corrugated-cardboard blank and with four side walls (1, 2) from each of which a flat zone (5, 11) has been partly punched out and folded downwards or upwards along one edge (7, 12). The four end flaps (8, 13) of these flat zones (5, 11) are bent over into the plane of the upper or lower end of the box and joined together, thus forming the top and bottom of the box. |
