<p>The tray comprises a base part, in the shape of a small cask, forming the bottom panel (1) of the tray with an upwardly extending peripheral flange (2) to which is attached one or more parts (3) that form the four sidewalls of the tray. Additional elements (4) may be added to the sidewalls to enhance structural stiffners. According to a further aspect of the invention, the plane of the bottom panel lies below the lower most edge (3a) of the sidewalls, providing a stepped portion which may be received into the open upper end of an underlying similar tray to provide a positive stacking means, the upper edge of the sidewalls (3c) of the underlying tray supporting the lower edge (3a) of the sidewalls of the overlying tray. The bottom panel and sidewalls may be formed from differing densities of cardboard. <IMAGE></p> |
