20100012614SEALING SYSTEM AND METHOD FOR SEALING CONTAINERS - A capping system in combination with a container having a mouth and a wall segment disposed proximate to the mouth is provided. The capping system includes a cap having a bottom for selectively covering the mouth, a jacket extending from the bottom, and a guarantee ring disposed at a distal edge of the jacket. At least one cam extends from an outer surface of the wall segment, is at least partially overlapped by the guarantee ring, and applies a force on the guarantee ring when the cap is rotated a predetermined distance relative to the container to at least partially sever the guarantee ring. The guarantee ring includes an overlapping region extending over the cam that provides clearance for the cam when the cap is initially installed on the container to prevent deformation of the guarantee ring during the installation.01-21-2010
