A seal ring for sealing a container. A seal ring has a base and a longitudinal axis extending therethrough, a radially outer portion, and an inner seal. The radially outer portion has a locking band that is configured to lock beneath an external engagement element of a container so as to secure the seal ring thereto. The inner seal is configured to be biased into sealing engagement with an inner finish surface of the container. The seal ring may be part of a package that also includes a container having a finish that comprises a sealing lip, an external engagement element, and an inner surface, and a foil sealingly and removably coupled to the base of the seal ring.
