ABSTRACT:
A large easy opening plastic lid, such as for a five gallon paint can, having a peripheral flange with an annular locking ring that engages an annular bead on a container sidewall to retain the lid in sealed engagement with the container. The flange is formed with a plurality of peripherally spaced frangible lines of weakness, which, when broken, segment the peripheral flange into separate flange segments, each having a segment of the locking ring. Following rupture of the flange along the frangible lines of weakness, each of the flange segments is independently pivotable between two positions, a first lowered position in which the respective segments of the locking ring engage with the container bead to securely retain the lid on the container, and a second raised or winged position in which all of the respective segments of the locking ring are disengaged from the container bead to facilitate easy removal and replacement of the lid. The lid is reapplied to the container by forcing the flange segments radially inward to a position beneath the locking bead to hold the lid to prevent splashing of the container contents.
