とを同時に行っているものである。The conventional manufacturing method involves punching an exhaust hole in a part of the hollow container body consisting of a metal outer container and a metal inner container, filling the space between the exhaust hole and the lid with brazing, and then vacuuming the hole. Heat treatment is carried out in a heating furnace under vacuum to perform a vacuum evacuation process and a lid brazing process at the same time.
ところが、この製造法は、蝋力λ蓋の周囲に均一に流れ
ると良好な蝋付けが行われる訳であるが、実際には隙間
か出来たりして１００％の製造法でないのが現状であっ
た。However, in this manufacturing method, good brazing is achieved when the wax force λ flows uniformly around the lid, but in reality, gaps are created and the manufacturing method is not 100% accurate. Ta.
本発明は、１００％に近い状態の製造法が出来る金属製
真空保温容器の製造法であって、その製造工程を添付図
面を参照に詳述すると次の通りである。The present invention is a method for manufacturing a metal vacuum heat-insulating container that can be manufactured in a state close to 100%, and the manufacturing process will be described in detail with reference to the accompanying drawings as follows.

。A metal outer container (1) such as stainless steel and a metal inner container (2)
) A hollow container body (R) is formed by a conventional method.

空容器体（ａ）を製造する。This hollow container body (a) is heated under vacuum in a vacuum heating furnace, evacuated through the screw hole of the nut (3), and the stopper lid (3) is screwed and tightened to the nut (3). In addition, the stopper lid (4) is deformed by a blow, and the stopper lid (4) is screwed into the nut (3) to produce a hollow container body (a) in a predetermined vacuum state.

製品となる。Since the present invention is configured as described above, when the hollow container body (a) is placed in a vacuum heating furnace and heat-treated under vacuum, the metal outer container (1) is connected to the metal outer container (1) through the screw hole of the nut (3). The air from the open gate of the outer container (2) is removed to create a vacuum state, and in this state, the stopper lid (4) is screwed onto the nut (3) and tightened.
When the stopper lid (4) is deformed by a blow and screwed onto the nut (3), a completed product of the hollow container body (a) is obtained.
真空加熱炉の中であるからロボットや自動供給装置等に
よって栓蓋（４）をナラ） ｆ３Ｊに螺合締め付けする
と良い。Since it is inside a vacuum heating furnace, it is best to screw the stopper lid (4) onto the bolt (F3J) using a robot or automatic feeder.

栓蓋（４）も変形度合の大きい材質のものにすると良い
。This nut (3) and lid (4) are made of metal outer container (1),
It is preferable to use stainless steel like the metal inner container (2), and the stopper lid (4) should also be made of a material that is highly deformable.

。As described above, the present invention allows the air inside the hollow container body (aJ to be removed to create a vacuum), and the seal is also tightly screwed into the nut (3) by utilizing the deformation of the stopper lid (4). Since the nut (3) and the lid (4) are screwed together, the nut (3) and the lid (4) are screwed together, so once the lid (4) is screwed together, it cannot be removed. This has the advantage of making the rail even more reliable.
尚本発明の場合ナツト（３）の熱膨張を利用すると栓蓋
