摘要

The box has a base (1) and vertical and horizontal side walls (2, 4) that are connected as a single piece with the base. The wall (4) or a section of the wall (4) is connected with the box over a weak spot. Guides (13), projections (17) and recesses (18) connect the wall (4) and/or the side wall section and the box. The spot includes a thin bar (11) weakened in comparison to a thickness of the wall (4). The bar is formed at a wall section (10) of a stage (9) of the section, where the former section is provided perpendicular to the base, and the stage is protruded in the box.
