| Abstract: |
A long-term storage container including a box-like titanium receptacle having a titanium primary cover and sealed by a seal ring of malleable precious metal clamped between the cover and the receptacle, with titanium/ceramic valves in the cover for use in exhausting air from the receptacle and replacing it with argon gas, with titanium/precious metal back-up plugs sealing the valves after the air has been replaced. A titanium secondary cover is bonded to the receptacle by a titanium weld, reinforces the seal by the primary cover, and has a cuttable integral metal wall for ease of opening, and an inner titanium container is disposed in the receptacle with elongated, resiliently flexible ribs in its walls engaging similar ribs on the adjacent walls to provide cushioning against crushing and shocks.

1. A long-term storage container for use as a time capsule, comprising:
- a box-like titanium receptacle having an open top side surrounded by a continuous rim, said rim having a flat top surface formed with a continuous seal groove therein;
- a primary titanium cover for said receptacle having a bottom sealing surface overlying said top surface;
- a seal ring of corrosion-resistant and malleable precious metal disposed partially in said seal groove and engaging said top and bottom surfaces;
- bolts extending through said primary cover and threaded into said rim and clamping the cover in sealed relation with said receptacle;
- at least one one-way valve in said cover composed of titanium and having a ceramic closure ball movable into an open position for evacuation of the receptacle and introduction of inert gas, and normally tightly closed;
- a back-up seal for said valve comprising a plug composed of titanium and a precious metal seal held in place in said valve by said plug;
- a one-piece secondary titanium cover overlying the primary cover and having an integral depending flange tightly surrounding the primary cover and said rim and bonded to said rim by a titanium weld, said flange having a thin-wall section cuttable with a knife for removal of the secondary cover;
- and an inner titanium container in said receptacle, said inner container having walls with outwardly extending, elongated and resiliently flexible ribs thereon;
- said receptacle having walls with inwardly extending elongated and resiliently flexible ribs thereon engageable with the ribs on the inner container to cushion the latter.
