Abstract:
1. Stackable tray for transport of fruit and horticultural products, constructed from a compact cardboard sheet in a single piece or by assembly of five pieces of compact cardboard, which define the base, greater side walls and end pieces, the last provided with prism-shaped reinforcements on the corners obtained by an enveloping construction of several sectors defined in an extension provided at each end of said end pieces, and further provided with means allowing the stable and correct stacking of trays, essentially characterised in that the end extensions of end pieces ( 3 ) are provided with folding lines which give rise to a first, second, third, fourth and fifth consecutive sections ( 8 , 9 , 10 , 11 , 12 ), where first sector ( 8 ) is larger than the second sector ( 9 ), with these sectors folded on each other and attached perpendicular to end piece ( 3 ) from which they originate, with first sector ( 8 ) attached by its external surface on the inner face of the corresponding side wall of the tray, while extreme fourth sector ( 11 ) and fifth sector ( 12 ), which also differ in size, are attached to each other through the external face of larger fifth sector ( 12 ) folded onto the inner face of the corresponding end segment of end piece ( 3 ), with third sector ( 10 ) remaining perpendicular to the diagonal of the corresponding corner; with double trapezoidal ridges ( 15 ) provided in correspondence with the upper edge of the concurrent prismatic reinforcements of each corner, said ridges created by upper extensions of both the inner and outer wall of said corner reinforcements, and where double upper ridges ( 15 ) are complementary of bottom openings or slits ( 5 ) provided for insertion of the former in the latter when the tray is stacked with other identical trays.
