<p>Process for 'returnable' packaging comprising two concave structures of plastic material, each having inside it a tray of plastic foam the dimensions and shape of which correspond to those of the upper and lower ends of the object to be carried, means for ensuring stability of said concave structures on the object, consisting of an elastic wrapping of a stretch film or a heat-shrinkable film, means for protecting the edges of the object in the area between the two concave structures and means for stable association in the form of a 'suitcase' of said concave structures when empty after extraction of the object, to enable the despatching firm to reuse said package. The bodies (51, 71) of the corner pieces (50) are placed side by side in the trays (20, 40) after which the concave structure (101) can be placed over the second concave structure (100) and firmly fixed by the clamps (90). Said clamps are closed by fitting their tips (92) inside the fissures (36) made in the edge (37) of the concave structure (101). The ends of said fissures become inserted in the notches (94) made in the elastic tips (92) of the clamps, thus firmly closing the 'suitcase' (120) formed of the two concave structures (100, 101) with handle (121).</p> |
