摘要

A stackable open topped box is provided in which the box is made of a folded blank of fluted sheet material. At least a part of a ledge panel is attached to an upper edge of a relevant wall so as to project over a pillar formation in a corner of the box. The pillar formation comprises first, second, third and optionally fourth flaps each attached to the other by a sulcation with the first pillar flap being attached to the ledge panel. An attachment flap may also be provided at each end of the wall having the flutes extending up its height. The arrangement is such that the flutes of all of the first, second, third and any fourth pillar flaps as well as any attachment flap extend in the direction of the height of the box.
