Abstract
Abstract Improvements in easy-opening containers of the type frequently referred to as ''''pop-top'''' containers used for beverages and other substances. The portion of the easy-opening container which is removed upon opening of the container, and which typically includes a tab of material torn or otherwise removed from the container and a pull ring attached to the tab and having a finger pull therein, is provided with container engagement structure which enables the ring to be secured to the container with the torn-out tab inserted through the opening in the opened container. The finger pull in the ring partially or completely surrounds the opening in the container, thus shielding the sides of the container opening from possible damage to the lips or tongue of a person drinking from the container and also providing a convenient, non-littering technique for disposal of the tornout portion.
