  • Method for canning food products
    Patent number: 4332826
    Abstract: A method and apparatus for canning food products in a container whose lid is held on by pressure differential between the interior of the container and the outside atmosphere, in which a pressure cover encloses the upper portion of the container and lid, and with the container, forms an enclosed pressure vessel with internal structure urging the container lid against the upper extremity of the container, and pressure control apparatus for limiting the pressure within the pressure vessel, and a base assembly for engaging the pressure cover and the container.
