    摘要： This invention relates to a closure which permits the opening of a hermetically sealed plastic container in a single action motion, which also maintains the hermetic seal under retort conditions. This closure includes a generally cylindrical side wall having threads along the inner surface thereof and a top portion having a metallic disk with its lower surface coated with a fusible coating, such as polypropylene. An annular flange is provided along the inner surface of the side wall to retain the metallic disk between the annular flange and an inwardly inclined inner surface portion of the side wall. A method is also disclosed for providing a hermetic seal on plastic containers using the closure of this invention.

    摘要： This invention is concerned with a closure which permits the sterile opening of a membrane sealed container in a single-action motion which also maintains a hermetic seal under retort conditions. This closure includes a generally cylindrical side wall having threads along the inner surface thereof, a top with an upper surface having a protective rim extending upwardly therefrom, with the top also having a dome assembly with the protective rim extending above such dome assembly. The dome has a top and bottom surface, with at least one plow member projecting downwardly from the bottom surface of the dome.
