摘要 |
Two longitudinal walls (2) are folded to adjoin a rectangular bottom (1). Two transverse walls (3), of height greater than the longitudinal walls, have articulated ends. A flap is placed against the internal face of the contiguous longitudinal wall (2) and passes above it. Each flap adjoining transverse walls (3) is extended by a reinforcing part (5). Against the face of each reinforcing part (5), which is turned inwards, is a tongue (10) joined by a fold to the contiguous longitudinal wall (2) or to a similar tongue (9) adjoining the longitudinal wall. The tongue (10) is fixed to the reinforcing part by gluing or stapling. ADVANTAGE - The reinforcing part is locked in position and provides greater resistance to bending.
