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.

An improved ferrule for sealing with a container of a dispensing device, the container having an annular bead extending about an opening in the container with the annular bead having an outer bead periphery defining an inner bead surface and an outer bead surface, the inner bead surface being generally planar and with the outer bead surface being generally annular and with the outer bead surface being established generally normal to the inner bead surface, comprising in combination: a ferrule comprising a central region and a peripheral rim; said central region of said ferrule being established for receiving the dispensing device for providing controlled fluid flow between the interior and exterior of the container; said peripheral rim of said ferrule extending outwardly of said central region; said peripheral rim of said ferrule having an inner peripheral region being generally planar and located proximate said central region; said peripheral rim of said ferrule having an outer peripheral region being generally annular and located remote said central region; said outer peripheral region of said ferrule being established generally normal to the said planar inner peripheral region of said ferrule; said inner peripheral region and said outer peripheral region of said ferrule being established for cooperating with the inner bead surface and the outer bead surface of the container; a bevel integrally formed in said ferrule between said inner peripheral region and said outer peripheral region for inhibiting said inner peripheral region of said ferrule from fully contacting the inner bead surface of the annular bead of the container when said ferrule is disposed upon the container; said bevel of said ferrule being deformed when said ferrule is sealed to the annular bead of the container to approximate the general shape of the outer bead periphery of the annular bead and to move said inner peripheral region of said ferrule proximate the inner bead surface to provide a sealing engagement between said ferrule and the container.
