Abstract
Abstract A tamper-evident lid for use with containers includes a surface to cover the container, and downward projections around the periphery of the surface which surrounds the mouth of said container. An interrupted ring is frangibly attached to the downward projections. A plurality of tamper-evident hooks are affixed to said ring. The hooks are visible through openings in the downward projections. The hooks engage the container, but when the lid is removed, the ring fractures away from the downward projection ring and the tampering with the package is apparent. In the preferred embodiment, a bead on the lid engages the sidewall of the container to provide a resealable, airtight seal.
