ABSTRACT:
A box is folded from a flat blank of sheet material. The flat blank of sheet material has a bottom portion, two side walls correspondingly connected via folds to first opposing edges of the bottom portion, and two end walls correspondingly connected via folds to second opposing edges of the bottom portion. The second edges extend perpendicular to the first edges. The end walls are of "double-wall" design, including inner and outer wall portions. Connecting portions are provided, with each connecting portion connected to intersecting edges of a side wall and a corresponding inner wall portion of an end wall and symmetrically foldable about a fold diagonally extending from a corner of the bottom portion such that in an erected state of the box the connecting portions are foldedly received between the corresponding inner and outer wall portions of each end wall. Engaging structures are provided at a vertical edge of the side walls for resiliently arresting the inner portions of the end walls for retaining them in a folded upright position. There is further provided a method of folding (erecting) a box from a flat blank of sheet material.
