Each wall in a first pair of opposing side walls (4, 5) is provided with at least one line of weakness (7, 9) extending from the top edge (11) of the wall to the base of the box (6), close to one of the walls (2) in the second pair of opposing side walls (2, 3). The lines of weakness divide the side walls into narrow sections (25, 26) and wide sections (27, 28) and are designed to be broken in order to detach the narrow sections from the wide sections, so that the side wall in the second pair close to the narrow section can be folded down to form a side opening (29) in the box. The side opening has a dimension in the plane of the base of the box which is equal to the distance between the walls in the first pair of side walls. |
