Abstract An annular flange extends radially from the rim around the open top of a container in a plane perpendicular to the axis of the container. The flange is integrally formed with the container and has a plurality of notches formed therein and extending radially inwardly from the outer edge of the flange. The flange has a planar top surface and tapered bottom surfaces forming a plurality of inverted inclined planes relative to the top surface, each extending from one of the notches to the next-adjacent notch in the same direction around the flange. A lid has a plurality of lock members formed thereon in the same angular relation as the notches of the container whereby each of the lock members is simultaneously passable through a corresponding one of the notches of the flange of the container. Each of the lock members comprises an arm supported by the lid and extending parallel to the lid in spaced relation below the lid in a manner whereby when the lid is positioned on the container with the lock members in alignment with the notches of the flange and such members are passed through the notches and the lid is turned, the arms of the lock members move into abutment with the bottom surfaces of the flange. If the lid is further turned, the arms securely seal the lid to the container via the flange.
A sealable canning container device, comprising a container having an open top with a rim therearound, a substantially annular flange extending substantially radially from the container at the rim thereof in a plane substantially perpendicular to the axis of the container, said flange being integrally formed with the container and having a plurality of notches formed therein and extending substantially radially inwardly from the outer edge of the flange, said flange having a substantially planar top surface and tapered bottom surfaces forming a plurality of inverted inclined planes relative to the top surface, each extending from one of the notches to the next-adjacent notch in the same direction around the flange; a lid having a plurality of lock members formed thereon in the same angular relationship as the notches of the container whereby each of the lock members is simultaneously passable through a corresponding one of the notches of the flange of the container, each of said lock members comprising an arm supported by the lid and extending substantially parallel to the lid in spaced relation below said lid in a manner whereby when the lid is positioned on the container with the lock members in alignment with the notches of the flange and the lock members are passed through the notches and the lid is turned, the arms of the lock members move into abutment with the bottom surfaces of the flange, and if the lid is further turned, said arms securely seal said lid to said container via said flange to provide a seal strong enough to preserve perishable foods for years; a plurality of stop projections each extending from a bottom surface of the flange at a corresponding one of the notches at the area of maximum flange thickness between top and bottom surfaces; and a circular groove formed in the top surface of the flange in spaced relation with the notches thereof and a corresponding circular protrusion extending from the bottom of the lid for fitting in the groove and sealing the container.

A sealable canning container device, comprising a container having an open top with a rim therearound, a substantially annular flange extending substantially radially from the container at the rim thereof in a plane substantially perpendicular to the axis of the container, said flange being integrally formed with the container and having a plurality of notches formed therein and extending substantially radially inwardly from the outer edge of the flange, said flange having a substantially planar top surface and tapered bottom surfaces forming a plurality of inverted inclined planes relative to the top surface, each extending from one of the notches to the next-adjacent notch in the same direction around the flange; a lid having a plurality of lock members formed thereon in the same angular relationship as the notches of the container whereby each of the lock members is simultaneously passable through a corresponding one of the notches of the flange of the container, each of said lock members comprising an arm supported by the lid and extending substantially parallel to the lid in spaced relation below said lid in a manner whereby when the lid is positioned on the container with the lock members in alignment with the notches of the flange and the lock members are passed through the notches and the lid is turned, the arms of the lock members move into abutment with the bottom surfaces of the flange, and if the lid is further turned, said arms securely seal said lid to said container via said flange to provide a seal strong enough to preserve perishable foods for years; a plurality of stop projections each extending from a bottom surface of the flange at a corresponding one of the notches at the area of maximum flange thickness between top and bottom surfaces; and a circular groove formed in the top surface of the flange in spaced relation with the notches thereof and a corresponding circular protrusion extending from the bottom of the lid for fitting in the groove and sealing the container.
