ABSTRACT:
An apparatus and a method is disclosed for an improved ferrule for sealing with an annular bead of a container. The ferrule comprises a peripheral rim having an inner peripheral region and an outer peripheral region. The outer peripheral region of the peripheral rim includes a portion thereof having a contour different from an outer bead surface of the annular bead of the container. The different contour portion of the outer peripheral region inhibits the inner peripheral region of the peripheral rim from fully contacting an inner bead surface of the annular bead of the container when the ferrule is disposed upon the container. The different contour portion of the outer peripheral region is deformed when the ferrule is sealed to the annular bead of the container to have substantially the same contour as the outer bead surface of the annular bead to provide a sealing engagement between the ferrule and the container.
