The lid has a base, a rim extending about a perimeter of the base for receiving the lip and at least one finger extending upwardly from the rim and toward the base for engaging an underside of the lip. A frangible membrane is associated with the fingers to facilitate outward tearing of the finger regions away from the sidewalls. Each finger has a length exceeding the distance between an inside of the lip and the sidewall.
