Abstract
A lid of molded plastic construction, includes a lid body and a cap attached to the lid body by a tether. The tether is substantially continuous with an adjacent peripheral edge of the lid body, with a tear zone between the tether and the adjacent peripheral edge of the lid body formed during molding of the lid. The tear zone is disruptable by application of a tearing pressure to free the tether from the peripheral edge.
