  • Patent number: 8322177
    Abstract: The present invention relates to a method and tooling suitable for handling closure blanks (5) having an external radius (6) at their cut edge at production speeds of about (1200) closures per minute. The external radius (6) limits formation of “angel hair” (a common problem in metal closure production). However, reversing the external radius causes a problem, when producing metal closures having a conventional inward curl at their peripheral edge. Accordingly, the invention proposes a modified curling rail (40) having a first portion (41) to uncurl the external curl (6) on the closure blank (5) and a second portion (45) to urge the straightened side wall of the closure blank (5) towards an inward curl.

  • Patent number: 7861874
    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.

  • Publication number: 20100089924
    Abstract: A metal container or component part of a metal container (e.g. a can end or sidewall of a can body) has an aperture defined by a cut edge about the periphery of the aperture, with a cover element sealed to the outward-facing surface of the can end so as to extend over and cover the aperture. A film of lacquer is directly applied (without the presence of an intermediate primer layer) to the inward-facing of the container/component part so as to coat the entirety of the cut edge and all or part of the inward-facing surfaces of both the can end and that part of the cover element located radially inward of the cut edge, thereby inhibiting corrosion of the cut edge. The invention is particularly suitable for can ends. The invention also relates to a method of making a can end to the invention.
