Snap-on, flexible lid

A plastic snap-on flexible lid for mounting on a top of a plastic container of the type having an annular rim which projects radially outwardly, said lid comprising, in combination, a top lid face, an annular peripheral flange, an inner annular wall spaced inwardly from said flange, said flange and said annular inner wall defining a downwardly facing annular recess to receive said annular rim on said top of said lid, said flange and said annular wall being generally upright, said flange including a plurality of spaced, flexible panels which are each connected to said flange only at a bottom edge of said panel and which extend upwardly and inwardly from said bottom edge, said flexible panels being deflected outwardly when said lid is initially forced down on said top of said container and springing back to radially inward positions to lock under said rim when said lid is forced fully down on said top of said container, and an aperture formed in said flange on each side of each of a plurality of said spaced panels, each said aperture being for the purpose of permitting entry of a cutting instrument to permit cutting down from said aperture to a lower edge of said flange to permit removal of said spaced panels and thereby facilitate removal of said lid, said flange being essentially free of a circumferential tear line.
