The object of this invention is a lid of truncated pyramidal shape made of thin transparent synthetic material to be used a-top a tray containing eggs, the object of this lid it to facilitate film wrapping of tray. Said lid is equipped with features to ease its placement on to the tray, provides for the avoidance of displacement and arching of its lateral walls during film wrapping; with features which would insure a stable and protected position of the eggs via small anti-shock air pockets; with features which would prevent the impaction of empty lids one to the other when stacked.

A lid to facilitate film wrapping of an open egg container, said lid being essentially of truncated pyramidal shape with a quadrangular top surface (15), in which is formed cone-shaped depressions (17), (18), (19) and having lateral walls (20), in which are formed grooves, each corresponding to a depression (17), (18), (19), said grooves and depressions, in use, being mounted upon internal and peripheral reliefs (37) and (34), respectively, of said container (33); said lead further including; recesses (16), (29), (30), which provide, in combination with the film wrapping, anti-shock pockets; a continuous rim (21) disposed about the quadrangular top surface, said rim, in use, being partially mounted upon the peripheral relief (34), said rim including at least one expansion on each side of the rim, each expansion being disposed towards the interior of the lid, and joined to the top surface (15) thereof via additional depressions (22), (23); and a reinforcement groove (24) with a marginal border (25), said groove being disposed at a lower part of the lateral wall (20); said top surface (15), further including cavities (28) defining reinforcement ribbing from which spacers (36) project toward the interior; said expansion, additional depression, rim, groove and border of the lid interacting with the container to reduce arching and breaking of the lateral walls during film wrapping.
