A molded plastic lid construction employs a peripheral edge section which includes first and second spaced, adjacent, radially discrete hoop sections or depending flanges connected together by a horizontal, annular section. The outermost hoop section or flange includes a projecting horizontal shelf extending partially around the lid. A slot is provided in the shelf for inserting the blade of a tool so that the outer hoop may be elastically deformed to facilitate release of the lid from the rim of a bucket, for example. A lid release flange depends downwardly from the shelf to provide a manual release flange that may also be used to elastically deform and reclose the lid from a bucket.

1. A molded plastic lid for use in combination with a bucket, said bucket having an open top with a circumferential top rim, said lid comprising, in combination:a central portion for covering the open top of the bucket; and a peripheral lid edge section for engaging and fastening to the top rim of the bucket, said peripheral lid edge section including a first outer depending gripping flange with an inwardly projecting lip for gripping the top rim of the bucket, said peripheral lid edge section further including a generally horizontal, radially outwardly extending shelf with an outer extension, and a lid-release flange extending downwardly from the outer extension of said shelf and at least partially radially outwardly from the first depending gripping flange, said lid-release flange extending at least partially circumferentially around the peripheral lid edge section, and at least one generally vertical slot through the horizontal shelf for receipt of a tool blade for elastically deforming the first gripping flange to disengage the inwardly projecting lip thereof from a bucket top rim. 2. The lid of claim 1 wherein the lid release flange comprises a depending extension flange from the first gripping flange for manual gripping and elastically deforming the first gripping flange to disengage from a bucket top rim.3. The lid of claim 1 wherein the lid edge section in radial cross section, at least in part, comprises a generally horizontal top run, having an outer radial extent and an inner radial extent, a generally vertical depending run at the outer extent comprising said first gripping flange, said lip comprising a radially inwardly extending run from the vertical depending run, said edge section in radial cross section further comprising a second downwardly directed flange from the inner radial extent to define a lid sealing surface for a top rim of a bucket, anda bucket in combination with the lid, said bucket having a top rim with a radial cross section including an inclined sealing surface in opposed sealing contact with said lid sealing surface. 4. The lid and bucket combination of claim 3 wherein the bucket rim in radial cross section comprises a shape compatible with the interior surfaces of the lid edge section and said bucket rim is compressed between the first and second spaced vertical and downwardly directioned flanges of the lid edge section.5. The lid of claim 3 or claim 4 wherein the lid release flange comprises an extension flange from the first gripping flange for manual gripping and for elastically deforming the first gripping flange to effect disengagement from the bucket rim.
