ABSTRACT:
A container lid has a depending insert having a thickness sufficient to have a groove formed in its peripheral edge, and a beverage container has an annular, radially inwardly extending protrusion formed in it that snaps into the groove when the insert is inserted into the container. The connection is so strong that the lid will not separate from the container even when the cup is filled with a beverage or food and inverted. The lid includes a peripherally positioned handle that enables facile removal of the lid, and the interconnection between the lid and the container includes a double seal that inhibits the risk of spillage.
