Abstract: Method of manufacturing a box and an arrangement permitting the secure but separable connection of an edge part of a first component to an adjacent edge part of a second component. Each edge part is provided with a number of connecting portions designed to produce the connection. The connecting portions for one of the edge parts and the connecting portions for the other edge part are so poritioned with respect to each other as to include, irrespective of their directional orientation lengthwise along the respective edge part, connecting portions which correspond to each other for interacting with one another.
