Abstract

The box, which can be made from a single sheet or from five separate pieces which are fastened to one another to form the box, is such that at the front ends, extensions project with transverse folding lines to form corner reinforcements. The extensions that form these reinforcements present four folding lines that define the sectors, which form an initial sector which is attached to the inner face of the side, a second sector with a diagonal disposition, a third sector which is attached on the inside of the front, a fourth sector which lies at right angles to the diagonal sector, and a last sector which is attached to one of the two halves of the inner face of the diagonal sector. At their upper edge the sectors present flanges which form projections perpendicular to one another, for positioning in matched opposing notches when the boxes are stacked.
