<p>The plastic rectangular tray has a perforated base and four vertical side-walls, there being a distance piece extending above the walls at each corner. The distance pieces (9) extend for a distance below the base and have recesses (10) at the bottom accommodating the tops (11) of the distance pieces of the tray below when all are stacked the same way up. Two or more the sidewalls have grooves (12) alongside the distance pieces accommodating the tops of those of an adjacent tray when stacked alternate ways up - e.G. when empty. Spacers are provided in the tray base to accommodate the bottom of the distance pieces of an adjacent tray in the stack.</p> |
