Abstract

A novel closure-making process and apparatus are disclosed for formation of plastic closures. The closures include a plastic closure cap which is compression molded to provide a closure having the requisite strength. The process includes steps for formation of a sealing liner within the closure cap if desired, with formation of a novel liner-retaining arrangement provided for secure retention of the liner within the cap. The process also includes steps for formation of a tamper-indicating pilfer band integrally with the plastic cap of the closure for formation of closures requiring a suitable tamper-indicating device.
