<p>The box is of cardboard, corrugated paper etc, with walls and a top opening closed by flaps hinging on the walls. One of the flaps has a tongue on each side, engaging in an opening in the adjacent sidewall, and of truncated arrow-head section. Each opening (12) is of the same shape as the tongue (11), but shorter than it in the lengthwise direction. The opening can be formed by a lug (13) cut out and remaining attached to the top edge of the sidewall, the lug being of the same shape as the opening. There can also be a flap (8, 9) attached to the top edge of the sidewall and partly closing the top opening in the box.</p> |
