Abstract:
A retortable container (C) or a retortable closure () for use with the container (C). A receptacle (R) is included that may incorporate fasteners (F) attaching the closure (). The closure () includes a retainer () received with a sealing barrier () formed from a polymeric material. The sealing barrier () includes a heat transfer material such as powdered metal in a volume that is between about 25% and about 65% of the closure () and an an oxygen barrier material such as a nanocompound or other barrier material having a relative volume of approximately between 10% and 60%. Variations of the closure () may incorporate seal layer of a thermoplastic elastomeric vulcanizate such as a santoprene and the heat transfer material may be an economically attractive powdered and/or oxide material such as zinc, aluminum, copper, nanotube, or similarly available material, which preferably is diffused throughout the closure ().
