• side edges, each side edge having a pivotable wing portion extending therefrom, each pivotable wing portion joined to its respective side edge by a hinge and moveable between a disengaged first position where the wing portion extends generally outwardly, and an engaged second position where the wing portion extends generally in the second direction, each wing portion including on an inner surface thereof a tab member configured for detent engagement with the rim of the container;
• and,
• corner portions extending between the side edges, each corner portion including a skirt portion extending, from a first wing portion around a corner and terminating at an adjacent wing portion, generally in the second direction, and each corner portion defining a recessed shoulder,
• wherein the lids are stackable upon one another, and wherein when a first lid of the pair of lids is stacked upon a second lid of the pair of lids, the recessed shoulders of the second lid each receive and support a respective one of the skirt portions of the first lid, such that the recessed shoulders of the second lid provide the only support for the first lid stacked upon the second lid.
