Abstract:
A box of plastics material comprising:a bottom wall with a rectangular shape, from which a pair of longer lateral walls and a pair of shorter lateral walls project, a first and second pair of support elements having respective bearing surfaces, wherein the support elements of the first pair of support elements are arranged along a first lateral wall and the support elements of the second pair are arranged along respective lateral walls orthogonal with respect to the first wall, each of said support elements having a corresponding recessed portion formed on the outer side of the box and adapted to receive the homologous support element of a box of the same type when the boxes are interpenetrated, whereby the box can be interpenetrated with a box of the same type when the two boxes have the same relative orientation and can be superimposed to a box of the same type when the two boxes have opposite relative orientation, wherein each of said support elements is arranged in correspondence with a corner formed by two adjacent lateral walls, and that each of said support elements have a centering portion upwardly projecting from the respective bearing surface and defining a centered position for a superimposed box, and wherein a first rib element and a second rib element are formed in correspondence with each recessed portion and arranged such that when the boxes are interpenetrated, the first rib element of the upper box rests on the bearing surface of the lower box and the second rib element rests on the upper portion of the centering portion of the lower box.
