Cardboard box with hinging lid - has oblong insertion slot in lid locking lug parallel to fold line

摘要

The box is made of a crboard or corrugated paper. It has a lid attached along a fold line and has an insertion lug hinging on a further fold line at the free edge. A slot in the lug runs in the direction of this line and accommodates a locking lug attached by a fold line to a section of the adjacent box wall, so as to swing out from the latter. In the locking lug there is an oblong insertion slot running parallel to the fold line joining it to the wall section.
