making at least one oblique crease or scoring in each angle of said box, one end being located at an intersection between said horizontal crease, another end being located at an upper ridge of one side wall, the oblique crease forming an angle of substantially 45° with said horizontal crease made in said one side wall; and

folding said upper portions back toward a center of said box, around said horizontal crease, at an angle of substantially 90°, and simultaneously, one on top of another, different flaps being folded back, separated by the oblique crease and being comprised of said upper portions of said side walls, around oblique creases and at an angle substantially of 180°, said upper portion being in a substantially horizontal plane.
