Storage vessels and related closure methods

A method for storing a material comprising:

• providing a container having a single wall with an inner surface and an outer surface, and a first open end, said container defining an interior;
• providing a closure lid adapted to be received within the open end and adapted to engage in a sealing relationship with said inner surface;
• providing a compression link having a container engagement surface and a closure lid engagement surface;
• and
• engaging said compression link between said closure lid and said inner surface such that said closure lid is retained by placing a portion of the closure lid under compression and a corresponding portion of inner surface under tension with said compression link contacting both said closure lid and said inner surface.

A storage system comprising:

• a container having a wall and a first open end, said wall having an inner surface and an outer surface;
• a closure lid configured to be inserted within said open end and adapted to engage in a sealing relationship with said inner surface;
• a compression link having a container engagement surface and a closure lid engagement surface, said compression link being configured to engage between and contact said closure lid and said inner surface to retain said closure lid in sealing engagement with said container;
• and
• an outer lid configured to engage a distal end of said container, wherein said outer lid has a lid hold-down member associated therewith for retaining said outer lid by exerting force on said outer surface of said wall of said container.

A storage system comprising:

• a container defining an interior and having an open end and a wall, the wall having an outer surface and an inner surface;
• the inner surface of the container having a first annular ledge and a first annular recess,
• the first annular ledge extending into the interior of the container,
• the first annular recess being located about a circumference of the inner surface and between the first annular ledge and the open end,
• the first annular recess having an upper surface;
• a closure lid sized and shaped to be inserted within the open end of the container and to engage in a sealing relationship with the inner surface of the wall,
• the closure lid having a second annular recess formed about an outer periphery thereof, the second annular recess being defined by a lower surface,
• the closure lid being movable between an open position, in which the closure lid is disengaged from a sealing relationship with the container, and a closed position, in which the closure lid is inserted within the open end of the container and contacts and is supported by the first annular ledge, the first annular ledge preventing further movement of the closure lid into the interior of the container;
• and
• a compression link sized and shaped to engage between and contact the closure lid and the inner surface to retain said closure lid in sealing engagement with said container,
• the compression link having a container engagement surface and a closure lid engagement surface, the container engagement surface and said closure lid engagement surface being operative to extend outwardly from each other such that, when the closure lid is in the closed position and the compression link is positioned to retain the closure lid in the sealing relationship with the container, said container engagement surface contacts the upper surface of the first annular recess of the inner wall and the closure lid engagement surface contacts the lower surface of the second annular recess of the closure lid.
