(see Publication No. 6), a plurality of solid brazing materials (7) are arranged at large intervals between the container body diagram and the lid (6), and the brazing materials (
7), the space (4) is evacuated by utilizing the large gap (C) formed between the container body and the lid (6), and as the brazing material (7) melts, The main body of the container was lowered under its own weight to force the molten brazing material (7) around the entire circumference of the opening (3).

において不完全になり、外筒１１）と内容器（２）の間
の空間（４）の真空度が低下する場合があった。The disadvantages of the above conventional method are as follows. In other words, since the solid brazing material (7) is arranged at large intervals in the circumferential direction of the opening (3), the molten brazing material (7) is
When pushing away the molten brazing material (7), depending on the case, the molten brazing material (7)
) flows to the outside of the lid (6) and the opening (al, ltl! ) may become incomplete in some parts, resulting in a decrease in the degree of vacuum in the space (4) between the outer cylinder 11) and the inner container (2).
本発明の目的は、ロー材の配置方法に改良を 。The purpose of the present invention is to improve the method of arranging brazing material.
加えて、容器本体と蓋体の確実な気密接合を行えるよう
にする点にある。In addition, it is possible to ensure a reliable airtight connection between the container body and the lid.
本発明による製造法の特徴手段は、ロー材を、容器本体
と蓋体の間において、外筒と内容器の間の空間に対する
開口の全周あるいはほぼ全周にわたって配置し、その後
で溶融して冷却固化することにある。The characteristic means of the manufacturing method according to the present invention is that the brazing material is placed between the container body and the lid over the entire circumference or almost the entire circumference of the opening to the space between the outer cylinder and the inner container, and then melted. It solidifies by cooling.
その作用は次の通りである。Its action is as follows.
つまり、従来、外筒と内容器間の空間からの排気のため
に容器本体と量体の間に大きな隙間を形成しなければな
らないと考えられていたが、このような既成観念から脱
却して、ロー材を開口の全周あるいははは全周にわたっ
て配置し、容器本体と黄体の間の隙間がｔｌとんど無い
又は小さい状態にして、確認実験を行った。In other words, it was previously thought that a large gap had to be formed between the container body and the mass in order to exhaust air from the space between the outer cylinder and the inner container, but we have broken away from this preconceived idea. A confirmation experiment was conducted with the brazing material placed around the entire circumference of the opening, or the entire circumference of the opening, so that the gap between the container body and the corpus luteum was almost absent or small.
その結果、空間の排気を十分に行え、かつ、容器本体と
蓋体の気密接合を完全にかつ信頼性高く行える事実を見
出したのである。As a result, they discovered that the space can be sufficiently evacuated and the container body and lid can be hermetically sealed completely and reliably.
本発明による効果は次の通りである。The effects of the present invention are as follows.
容器本体と蓋体の気密接合を確実に行えるから、外筒と
内容器間の空間を長期にわたって十分な真空度に維持で
き、断熱性能において優れた金属製魔法瓶を確実に提供
できるようになりた。Since the container body and lid can be reliably sealed, the space between the outer cylinder and the inner container can be maintained at a sufficient degree of vacuum for a long period of time, making it possible to reliably provide metal thermos flasks with excellent insulation performance. .
