Semi-rigid material cutout blank i.e. cardboard, for forming parallelepipedic shaped box to pack food product i.e. pizza, has foldable shutter and side pavements comprising mutual co-operation unit formed of tabs and notches

摘要

The blank (2) has a transverse pavement arranged opposite to a connection strip (22), where the pavement is extended by a foldable shutter (28) by folding along a folding line (28a) parallel to a folding line (25a) of a rectangular panel (20). Pavements (26, 27) are arranged and connected in periphery of another rectangular panel (21) by folding lines (26a, 27a) to form flaps of a lid. The shutter and side pavements (23, 24) of the former panel comprise a mutual co-operation unit formed of tabs (29) and notches (40) for closing and locking a parallelepipedic shaped box.
