Zusammenfassung:To provide a manufacturing method of an insulating container capable of forming a vacuum heat insulation layer between an outer container and an inner container without providing a slip for degassing.SOLUTION: The present invention discloses a manufacturing method of an insulating container 1A having a metallic outer container 2 and a metallic inner container 3 each having open one end, in which mutual open end sides are bonded in the state where the inner container 3 is stored inside the outer container 2, and a vacuum heat insulation layer 4 is provided between the outer container 2 and the inner container 3. One component 2a and another component 2b constituting the outer container 2 are bonded together by welding in a decompressed state, thereby forming the vacuum heat insulation layer 4 between the outer container 2 and the inner container 3.SELECTED DRAWING: Figure 2 【課題】脱気用のスリットを設けることなく、外容器と内容器との間に真空断熱層を形成することを可能とした断熱容器の製造方法を提供する。【解決手段】一端が開口した金属製の外容器2及び内容器3を有して、外容器2の内側に内容器3を収容した状態で互いの開口端側が接合されると共に、外容器2と内容器3との間に真空断熱層4が設けられた断熱容器1Aの製造方法であって、減圧された状態で、外容器2を構成する一の部材2aと他の部材2bとの間を溶接により接合することによって、外容器2と内容器3との間に真空断熱層4を形成する。【選択図】図2
