ABSTRACT:
A a lid for sealing a container. The lid adheres to the container by no more than a vacuum formed within the container. The lid is formed of a substantially circular panel having a flanged perimeter and a concave depression on an upper side of the circular panel. A pressure release hole extends through the concave depression of the circular panel and sanitary varnish is disposed on a lower side of the circular panel. A first adhesive material is applied to the lower side of the lid by fusion to the sanitary varnish to form a thin film over the release hole, and a second adhesive material is disposed in the concave depression on the upper side of the lid to form a removable seal. The second adhesive material has the same properties as the first adhesive material.
