て栓蓋４をナツト３に螺合止して所定の真空状態
の中空容器体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. The cap 4 is screwed onto the nut 3 by being deformed by a blow, and a hollow container body a in a predetermined vacuum state is manufactured.
尚栓蓋４の外側にナツト３の雌ネジに合わせて
雌ネジを形成していると共に上面に回動並びに打
撃用の孔５を形成している。 A female thread is formed on the outside of the stopper lid 4 to match the female thread of the nut 3, and a hole 5 for rotation and impact is formed on the top surface.
更に、この場合、ナツト３と栓蓋４との間に接
着剤を介入させることにより完全なシールが行わ
れることになる。 Furthermore, in this case, a complete seal is achieved by interposing an adhesive between the nut 3 and the stopper lid 4.
本発明は上述の様に構成したから中空容器体ａ

した上、栓蓋４に打撃を与えて変形させて栓蓋４
をナツト３に螺合止すると中空容器体ａの出来上
がり製品となる。 Since the present invention is configured as described above, the hollow container body a
When placed in a vacuum heating furnace and subjected to heat treatment under vacuum, the air between the metal outer container 1 and the metal inner container 2 is removed through the screw hole of the nut 3, creating a vacuum state. After screwing and tightening the stopper lid 4 to 3, the stopper lid 4 is deformed by giving a blow to the stopper lid 4.
When screwed into 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ツトや自動供給
装置等によつて栓蓋４をナツト３に螺合締め付け
すると良い。 Since it is inside a vacuum heating furnace, it is preferable to screw and tighten the stopper lid 4 onto the nut 3 using a robot, an automatic feeder, or the like.
この栓蓋４を変形させる方法はドライバー溝や
ポンチ穴５を作り、このドライバー溝やポンチ穴
５を鏨やポンチ等で強く叩くと良い。この場合金
属製内容器２を下型にのせて打撃すると良い。 A good way to deform the stopper lid 4 is to create a driver groove or punch hole 5, and then hit the driver groove or punch hole 5 strongly with a chisel, punch, or the like. In this case, it is preferable to place the metal inner container 2 on the lower mold and impact it.

もあるから栓蓋４は一旦螺合止されると抜け止め
となつて一層確実なシールが行われる等秀れた特
長を有するものである。 The nut 3 and the stopper lid 4 are preferably made of stainless steel like the metal outer container 1 and the metal inner container 2, and the stopper lid 4 is also preferably made of a material that is highly deformable. In this way, the present invention can simplify the hollow container body a.
The air inside is 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, so a highly accurate seal can be achieved. Since the stopper lid 4 is also screw-fitted, once the stopper lid 4 is screwed together, it is prevented from coming off and has excellent features such as a more reliable seal.
尚本発明の場合ナツト３の熱膨張を利用すると
栓蓋４が一層確実に螺合止されてベストなシール
が行われる。 In the case of the present invention, if the thermal expansion of the nut 3 is utilized, the stopper lid 4 will be more securely screwed together and the best seal will be achieved.
