- the inner container 4 can be supported from the lower side by using a pair of thin pipes 6 and 7 joined to the outer lid 3 of the outer container 2. At this time, the heat source stored in the inner container 4 can be supplied into the inner container 4 from one or both of the thin pipes 6 and 7.
- the joining of the pair of thin pipes 6, 7 and the outer lid 3 and the inner lid 5, the joining of the outer lid 3 and the bellows-like cylindrical surface 2a, the cylindrical surface 2a and the upper surface 12 Joining, joining of the inner lid 5 and the cylindrical surface portion 4a, and joining of the mounting flange 8 and the cylindrical surface portion 2a are the same as described in the configuration in which the inner container 4 shown in FIG. It can be performed.
- the upper surface portion 14 of the inner container 4 is integrally formed with the cylindrical surface portion 4a by deep drawing.
- the upper surface portion 12 of the outer container 2 is formed in a curved shape that protrudes in a curved shape to the outside, and an exhaust port 11 is formed.
- the cylindrical surface portion 4a of the inner container 4 is simply formed in a cylindrical surface shape without being formed in a bellows shape, but in the case where the size of the inner container 4 is large, etc. If it is necessary to improve the strength of the cylindrical surface 4a, the cylindrical surface 4a can be configured as a bellows-like cylindrical surface as required.
- the present invention can be suitably applied as a sealed double container made of metal.

Abstract
Description
これによって、内容器内の熱が外容器側に逃げていく割合が多くなり、内容器内における温度を長時間に亘って維持しておくことが難しくなる。
即ち、本願発明は、外容器内に内容器を離間させて配設した金属製の密閉二重容器であって、前記内容器と、前記内容器の開口部を塞ぐ内蓋と、前記外容器と、前記外容器の開口部を塞ぐ外蓋とが、全て薄板の金属材によって構成され、前記内容器が、前記内蓋と前記外蓋との間に接続された少なくとも一本以上の薄肉パイプによって、前記外容器に支持され、
前記薄肉パイプの両端部が、前記内蓋及び前記外蓋に形成したバーリング形状の接続孔にそれぞれ差し込まれた状態で、前記内蓋及び前記外蓋にそれぞれ接合され、前記内容器の内部空間が、前記薄肉パイプを通って前記外容器の外部に連通していることを最も主要な特徴としている。
更に、本願発明では、前記薄肉パイプを構成する金属材が、前記内蓋と前記外蓋とを構成する金属材の熱伝導率よりも低い熱伝導率を有する金属材で構成されていることを主要な特徴としている。
また、本願発明では、前記内容器が、前記薄肉パイプによって吊り下げられた状態で配されていることを主要な特徴としている。
更に、本願発明では、前記外容器と前記内容器との間の空間が、真空状態に保持されていることを主要な特徴としている。
このように構成することによって、内容器と外容器とは、薄肉パイプを介してのみ接続している構成になるので、内容器と外容器との間における断熱性を大幅に向上させることができる。
フランジ部5cを介して内蓋5と円筒面部4aとを接合することにより、フランジ部5cによって内蓋5と円筒面部4aとの接触面積を広く構成しておくことができる。そして、内蓋5と円筒面部4aとを薄板で構成しても、接合部の接触面積を広く構成しておくことができ、内蓋5と円筒面部4aとの接合強度を高めることができる。
尚、比較用の密閉二重容器としては、外容器及び内容器を薄板の金属材で構成し、外蓋及び内蓋と、外蓋及び内蓋に接続するパイプと、をそれぞれ板厚の厚い金属材で構成している。
即ち、外容器2及び内容器4としての強度を維持することができる構成であれば、それらの構成を採用することができる。
