  • Method of making a frangible port protector
    Patent number: 4415393
    Abstract: A method of manufacturing a tear-off port protector for a container comprises placing flexible, typically extruded tubing on a mandrel that fills the bore of the tubing, with the tubing preferably outwardly stretched by the mandrel. A cutting blade is spaced a predetermined distance of less than the tubing wall thickness from the mandrel. One then causes the cutting blade to form an annular cut about the tubing, while maintaining the predetermined distance, and thereafter one removes the tubing from the mandrel.
