摘要

The folded box has an inserted sealing portion and side flaps joined to its sides. Each side flap (7) is also joined to an edge of the lid (2), and has a fold line (6) emanating from that of the lid. This fold line is punched right through for part of the way from the lid fold line. The punched-through portion (11) can extend along a curve in relation to the fold line, or can alternatively be straight and on the fold line itself.
