Claim:
A plastic lid for large commercial and industrial solid waste containers, comprising: a central area of said lid having a single wall with a plurality of raised ribs spaced apart by intervening wells; front, rear and two side perimeter edges connected integrally to said central area, said perimeter edges having a substantially hollow double wall cross-sectional configuration; a plurality of hinge lugs along the rear perimeter edge, said hinge lugs including a plurality of tubular portions connected together by tubular web portions, said plurality of tubular portions being radially thicker than said tubular web portions; said lid being substantially symmetrical for permitting alternate stacking with similar lids with adjacent lids facing in opposite directions; and the front edge of said lid being shaped to provide vertical clearance for said hinge lugs on said rear edge when the lid is stacked with edges of adjacent lids being in engagement and adjacent lids being reversed in orientation; whereby said similar lids may be stacked with the vertical height of the stack being equal to the number of lids multiplied by the thickness of the hollow edges, plus the height of the ribs of one lid above the hollow edge thereof.
