Folded box with integral reinforcement - has two superimposed and bent bands with recesses forming cross support

摘要

The box has a shape formed of movable parts with webs. These form the basis of a cross stay (4) and are fitted integrally in a band (3) at the base (1) of the box, the bottom passing under the band. The ends of the band continue beyond the web notches and are lifted to form the box fronts (3,3'). There can be two bands, crossing perpendicularly, superimposed at the crossing. The other ends are similarly lifted to form the box sides (22,22'). The two crossing bands can be of different materials.
