Subsequently, an appropriate brazing material 15 is placed in the concave portion 14 of the content body 5, and vacuum suction is performed in a vacuum heating furnace as usual, so that the space between the outer body 4 and the content body 5 becomes the vacuum space S2. Then, the brazing material 15 is melted by heating, and the exhaust hole 8 is closed with the brazing material 15 which has been melted (see FIGS. 4 and 5).

  The sealing means for the exhaust hole 8 includes a sealing means for melting the brazing material 15 and sealing the exhaust hole 8 with the sealing plate 16 as shown in FIGS. Thus, a sealing means using a copper tip tube 25 may be used, and in the case of this tip tube means, the portion to be vacuum-sealed for protecting the tip tube 25 and the protective material 26 covered by the tip tube 25 from heat It is significant that the contents are provided in the contents body (the tip tube 25 is made of copper, and thus is thermally expanded and damaged in a high temperature environment). In addition, the concealing member 27 is arranged by providing the tip tube 25 in the content body. Reference numeral 18 denotes a handle member disposed on the top of the lid body 6.

  In the present embodiment, the height of the peripheral wall portion 6 a of the lid 6 is substantially the same as that of the peripheral wall portion 3 a of the container body 3.

  This is because when the lid body 6 is disposed in a fitted state with respect to the container body 3, by increasing as much as possible the overlapping portions of the peripheral wall portions 3a, 6a, the inside and outside of the container body 3 Therefore, it is possible to obtain a state in which heat hardly enters the inside. In the present embodiment, the lid body 6 is disposed in a fitted state with respect to the container body 3, but the lid body 6 may be disposed in the container body 3 in a fitted state.

  The lid 6 is provided with a locking member 22a constituting a separation preventing means 22 for preventing separation from the container body 3 at a position facing the outer peripheral surface at the lower portion.

  This locking member 22a is made of a metal (stainless steel) having an appropriate heat resistance as shown in FIGS. 1 and 2 and formed in a plate shape. It is provided so as to be freely swingable in the direction, and is configured such that its front end locking portion can be locked to the locking portion 22b provided in the container body 3 described above.

  The separation preventing means 22 may be appropriately adopted as long as it has a configuration that exhibits the characteristics of this embodiment, such as a type in which a band made of a heat-resistant material is wound.

  Reference numeral 19 denotes a disk laminated body 19a in which a rod body 19a ′ for fitting a hole 20a provided in a disk 20 such as a CD or a DVD is installed in the center, and the rod body 19a ′ and the laminated body of the disk laminated body 19a. This is a disk rack composed of a lid 19b fitted on the disk.

  That is, when manufacturing the container main body and the lid, it is assumed that an exhaust hole is provided in the outer body that constitutes the container main body and the lid, and a vacuum sealing process is performed in the exhaust hole (conventional manufacturing aspect). In general, an exhaust hole is provided in the outer container and vacuum-sealed, and the outer container is directly exposed to a high-temperature environment, particularly in the case of a cover-fitting structure. There is a concern that heat may enter from the exhaust hole provided in the interior.

  Specifically, for example, the vacuum sealing process is generally performed using a brazing material (and a sealing plate), but in an environment (for example, a fire) higher than the melting temperature of the brazing material. In this case, if a structure for exhausting from the exhaust hole provided in the outer container is adopted, the vacuum-sealed part is directly exposed to high-temperature heat and the brazing material is melted (a general soldering). The melting temperature of the material is 900 ° C. to 1050 ° C., and the high temperature environment due to the fire is 1000 ° C. to 1200 ° C.), when heat enters the inside from this vacuum sealed part (exhaust hole) There is.

  In this regard, if a structure for vacuum sealing treatment is adopted in the exhaust hole provided in the content body, this vacuum sealed part does not reach the melting temperature of the brazing material, so this vacuum sealed part (exhaust hole) Therefore, heat does not enter from the inside, so that the heat insulating performance is surely exhibited.

  Note that the present invention is not limited to this embodiment, and the specific configuration of each component can be designed as appropriate.
