Abstract
A lid for a container is disclosed that has a series of seals. The first seal is a cork seal mechanism that is forced against the container interior at a top portion of the container. The second seal is created by at least two ribs that produce a spring-like force against the container. An additional stretch fit seal can be incorporated into the lid. A tear strip can also be incorporated into the lid with windows immediately above the tear strip, thereby forming slits in the skirt to aid in removal of the lid.
