<p>The blank has a base portion (1) and peripheral edge portions folded to define side walls, one pair (2,3) of a single layer of cardboard, the other pair (4,5) of double form. The region (8) of the fold defines a support surface for an identical tray, when stacked. The outermost parts of the end walls have folded extensions (16) at the corners of the tray, which define upstanding stacking projections (9,10) and recesses (16). The innermost parts of the folded wall portions have extensions (11,12) which extend diagonally across the corners to brace them.</p> |
