Box with four side walls, a box base and at least one handle located on a side wall in which have been made, at least in specific zones, hollow channels for closure reinforcement in the contour thereof, which are formed by means of the blowing-in of gas. This produces a high degree of rigidity with respect to torsion and an increase in the stability vis-à-vis breaking of the transportation handles. <IMAGE>
