The invention consists in oversizing the corner pieces 6 [lacuna] lateral extension of their walls and which will give rise to the conventional columns for stiffening the vertical edges of the box, each pair of corner pieces 6 which frame a major lateral wall 3 also being connected directly together by means of the residual strip 17 which in principle it is necessary to remove in order to give said lateral wall 3 the appropriate height, fold lines 18 being made to correspond with the ends of the residual strips 17, which make them independent of the actual corner pieces 6, so that when the box is made up and at the same time as the corner pieces are fitted to the walls 5 the residual strips 17 are fitted to the bottom 1 of the box in a situation of symmetry with respect to the major axis of the bottom, stiffening it. <IMAGE>
