The end walls are formed by means of extreme extensions of the parts constituting the side walls, in whose prolongations, by gluing a sector, two bellows and flat projections are formed, and are completed by prolonged flaps of the central part they fold outwards, so that the bellows are folded and the edges of the part of this flap that is to constitute the inner wall in the cuts that originated the flat projections, the next section of these flaps that form the backs of the front walls.
