No more pull rings.
Twisting the cap breaks two safety seals:
1. First, the seal to the safety ring at the base of the cap will break.
2. Second, "teeth" on the inside of the cap are extended down through the carton, opening the flap and creating the hole in the package.
Twist cap to open, our caps do not use a pull ring. As the cap is twisted counterclockwise, the plastic "teeth" cut through the carton creating the pour opening.
