<p>The tray has a series of integrated laminates defining the tray bottom, a pair of sidewalls, and a pair of lateral walls. The sidewalls and lateral walls are individually provided with upper flanges to close the tray. The upper flanges have connecting portions that engage each other. A groove is formed on each corner of the upper flange, such that the upper flange can be inserted into the groove on the corner of another flange. The tray is made of very resistant material, and can be piled on top of another similar tray.</p> |
