Abstract: A container lid is provided having a lid insert constructed of a paper-based material and a peripheral ring constructed of a plastic material. The ring is configured to be separated from the lid insert upon disposal. The lid insert includes a peripheral rim extending outwardly from a central cover portion. The ring includes an outwardly extending flange and a skirt depending downwardly from the flange. A first undercut extends inwardly from the skirt defining a channel sized and shaped for receiving an outer edge of the lid insert's peripheral rim. The channel may alternatively be sized and shaped for also receiving an outer edge of a peripheral rim of a container base to which the lid is attached. Another embodiment includes a second undercut located beneath the first undercut and defining a second channel into which an outer edge of the rim of the container base may be received.
