Abstract
A resealable can end is provided including a neck (10) and a cooperating cap member (12) which can be sealed onto and removed from the neck, and is capable of containing product under pressure or vacuum if desired. This end may be added, by convention seaming methods, such as roll seaming or by appropriate adhesive, to a container body, or may be formed integrally with container bodies. The venting feature of the end will achieve a controlled release of differential internal-to-ambient pressure upon initial opening of the cap, and may also provide resealed containment of partial contents retained in the container, although the contents will no longer be under pressure or vacuum, as the case may be. The end may be applied to, or incorporated in, containers made of various material, such as aluminum, coated steel, or selected plastics.
