摘要

The packing box is made from a single sheet of material and has a base (1) with integral sides (5 and 6) formed by bending the card along the edges. The ends (2 and 3) are similarly formed, and have an outside reinforcing tab (9) integral with the sides to form a corner. The flap (10) is folded down horizontally inwards to fit under the lid flaps (7 and 8) which are an extension of the sides. The ends and the covering flaps are fitted with overlapping ventilation holes (4 and 11).
