Abstract (en)
[origin: EP0109875A1] 1. Packing tray of corrugated cardboard, of the type comprising a base 12, two longitudinal walls 14, two transversal walls 16 higher than the transversal walls and each terminating at its ends in two angular returns 18, two horizontal entablatures 20 advancing parallel to the base from horizontal upper edges of the transversal walls, and two independent reinforcement sheets 24 applied against the transversal walls and designed to increase the resistance to "bundling" of the ends of the tray or the heads 28 which are defined between the base and the entablatures, the said tray being characterized by the fact that the reinforcement sheets 24 are held in position by reason of the fact that their horizontal edges fit into grooves 34 approximately equal in thickness to the reinforcement sheets and formed by compressing the cardboard along folding lines by which the lateral walls 14, 16, are articulated to the base and to the entablatures, the said reinforcement sheets having for this purpose a height 1 substantially equal to the internal height, h, of the transversal walls 16 puls the sum of the depths of the two grooves 34 into which each of them is fitted.
