Abstract: A closure that includes a top panel and a skirt extending downwardly from a peripheral edge of the top panel is provided. The closure includes a tamper band which extends downwardly from the skirt and a multi-seal, seal portion which is located inside of the closure above the threads where the top panel is joined to the skirt. The tamper band and seal portion are configured to improve the removability of the closure from a mold.

Abstract: A system and method for injecting pressurizing fluid into a filled and sealed container is provided. The container is filled with a product and is then sealed with a closure. A pressurizing fluid is injected through the closure into the container cavity after sealing and filling.

Abstract: A closure that includes a top panel and a skirt extending downwardly from a peripheral edge of the top panel is provided. The skirt terminates in a plurality of spaced thread engagement flanges for engaging the thread of the neck of a container. The closure includes a polymer-filled channel which connects the top panel to the skirt. When engaged with the threaded neck of a container, the neck is forced into the channel and engaged by the polymer so that the channel and polymer provide lateral rigidity to the neck. This rigidity prevents the neck from deflecting from the forces resulting between the threads and thread engagement lugs when the forces therebetween are increased to the level required to adequately seal the closure to the container.

Abstract: A closure including a top panel and a transition section extending from a peripheral edge of the top panel is provided. The closure includes a skirt extending from a peripheral edge of the transition section such that the skirt extends away from the top panel. The skirt includes a plurality of projections extending outwardly and away from an outer surface of the transition section.

Abstract: Retortable packages including plastic closure caps are disclosed. The closure cap includes an end panel and a liner applied to the end panel. The finish contacting surface of the liner has a profile that is generally arc-shaped or torroidal-like prior to contact with the finish.
