Abstract: In a vacuum heat insulating double walled container 1, adsorbent blocks 30 are formed in block, and each of the adsorbent blocks 30 disposed on the peripheral surface of a sample storage container 25 is placed on a partition plate 27. Moreover, an inner container 10 is hang in an outer container 3 using a connecting tube 20 formed of a thin material having an uneven outer peripheral surface, and a heat insulating tube 40 is disposed on the inner surface of the connecting tube 20. Further, as to a workpiece carrier 50 as a fixing device, a carrier guide 52 is in close contact with the heat insulating tube 40, and a plate-like portion 54 and a workpiece storage portion 51 are disposed in a non-contact state with respect to the sample storage container 25.

Abstract: The metallic sealed double container of the present invention includes an outer container, an inner container, an outer lid for the outer container, and an inner lid for the inner container, all of which being formed from thin metallic sheet. Connection holes are formed in the outer lid and the inner lid by burring, and both end parts of thin-walled pipes are respectively connected while inserted in the connection holes. The inner lid is joined to the inner container, and the outer lid is joined to the outer container, thereby constituting a metallic sealed double container in which the inner container is isolated in the outer container. As a result, the weight of the metallic sealed double container is reduced, the temperature in the inner container can be maintained over long periods of time, and the heat-insulating effect of the resulting sealed double container is high.
