  • Folding box cutout and folding box folded therefrom
    Patent number: 8695870
    Abstract: A folding box cutout has wall units that can be folded along the fold lines, a lid unit that can be folded about a lid folding line, and a bottom unit that can be folded about a bottom folding line. In the transport state, the folding box cutout is folded to form a flat folding box, which is filled and closed by the lid unit and the bottom unit. A corrugated cardboard unit lies against the inner wall of the wall units and is connected to the inner wall of the folding box cutout so that the folding box cutout and the corrugated cardboard unit form a unit that can be handled as one piece for folding it flat and for unfolding it. The corrugated cardboard unit is present on each inner wall of the wall units, particularly all around, after the flat folded folding box has been erected.
