Abstract
An easy opening container component and a method and tools for forming the same are provided in which the container component includes a substantially rigid inwardly displaceable opening panel including a V-shaped weakening indentation therearound in the public or exterior surface of the component providing a fracturable web at the root of the indentation adapted to be fractured by inwardly directed pressure digitally applied against an integral outwardly projecting deflectable portion of the container component around the opening panel. The V-shaped indentation may be formed in the exterior surface of the container component while the opposite surface lies against a rounded anvil which forms an inwardly concave undersurface on the non-public surface of the container component, and may be formed in sheet metal without destroying the integrity of a protective coating on the interior surface thereof.
