Portola Packaging, Inc: Inner pull ring

The Easy-to-Open Inner Pull Ring closure from Portola Packaging is a 2-piece snap-on closure consisting of a threaded injection-molded PE bottom component and an injection-molded top PP component that screws onto the threads of the PE piece.

Both pieces are mated as the cap is snapped on to the bottle’s neck finish. When the consumer screws off the top piece, the bottom piece remains on the neck finish, and a pull ring in its center provides tamper-evident protection. Closure works with any PET or HDPE bottle and is designed to run on most existing capping equipment.
