Abstract
A tamper evident container lid is provided that includes a lid body configured to cover the opening of a base container having a top rim. The lid body has a skirt extending therefrom. The skirt has an annular score line and an annular fold line extending therearound. An outer band of the skirt extends between the score line and the fold line, and an inner band is folded inwardly to be in opposing relation to the outer band and extends upwardly from the fold line to an upper free edge. When the container lid is sufficiently applied to the base container such that the free edge slides downwardly past a top rim of the container, achieving a proper closure, an attempt to remove the lid will cause a plurality of sections of the inner band to engage the top rim and impede removal of the lid from the base container.
