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.

Abstract: A closure that can be threadingly screwed onto an associated container includes a body having a thread form for engaging a thread form on the container.

Abstract: A tamper evident container closure seal with an integral pull opener is constructed from one or more layers of frangible sheet material adhesively bonded to one or more layers of strengthening sheet material. The one or more strengthening layers each contain one or more duplicate void configurations that form a weak area in the multi layered seal only in the area of the void configuration. When a consumer forces a finger into the seal when bonded to the rim of a container the applied pressure forces the seal to break open and tear only in the weaker area of the void configuration while the peripheral portion of the seal remains bonded to the container rim. The broken open center portion of the seal then forms a pull tab that can be partially connected which allows the pull tab to be lifted back out and pulled from the container.
