Abstract
A closure for a container having generally helical threads on the neck finish is formed from a one-piece cap shell of thermoplastic material including a top wall and a peripheral skirt, the skirt having a plurality of spaced, hard, flexible generally vertical thermoplastic ribs integral with the shell for contacting the threads of the container. Each rib is so constructed and arranged that it has sufficient resistance to cold flow that it only slightly flexes and bends around the thread to form a shallow indentation on the rib when the rib is forced into contact with the thread, the indentation being sufficient to provide purchase on the threads for removing the closure.
