The tray is obtained from a sheet 1 which constitutes the base, and four strips 6, 7 which form the faces thereof which are glued on folded flanges of the base. The faces have wings 10, 11 at their ends which are folded and glued on the adjacent faces. Two faces 7 are equipped with fins 12 which project from the upper edge and with notches 13 on the lower edge which fit together when the trays are stacked, immobilising them laterally. <IMAGE>
