Abstract
The disclosed invention describes a container end that can be easily opened and does not rely on a conventional metal tab, riveted onto the end, thereby avoiding the problems and the cost associated with such a tab. The invention utilizes a traditional container end shell with a separate and distinct piece that is formed independently and is inserted into a countersink which is placed on the outer surface of the container end shell. The removal of this separate piece exerts a force or causes a change in the properties of the container wall in the countersink area, initiating and proliferating a discontinuity in the container wall, thereby creating an opening in the container. This change in the properties of the container wall can be mechanical, chemical, thermal or any other modality, which has the ability to influence the integrity of the container wall.
