Blank for stackable carton - in which bottom flaps create formation to engage with formation on top of lower box in stack

摘要

The blank for erection into a box includes four panels which form the side walls of the erected box and flaps joined to the panels. The flaps, in the erected condition of the box, are folded inwardly so as to overlap one another to constitute the top and base of the box. The flaps are formed to define, in the erected condition of the box, formations on the base of the box which inter-engage with formations on the top of an identical box on which the box is stacked. This arrangement inhibits relative lateral movement between the two or more stacked boxes.
