【産業上の利用分野】この発明は、ポットのような断熱
容器として用いられる金属製断熱二重容器に関するもの
である。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a metal insulated double container used as an insulated container such as a pot.
【0002】[0002]
【従来の技術】金属製の真空二重容器は、内容器に気密
を保持して外容器を被せ、その両容器間の間隙に真空層

ステンレススチールであり、製造コストの点から、両容
器とも同一仕様のものが用いられる。2. Description of the Related Art A vacuum double container made of metal has an inner container covered with an outer container while keeping airtightness, and a vacuum layer is formed in a gap between the two containers. The material of the outer container of the inner container is stainless steel, and both containers have the same specifications in terms of manufacturing cost.

【発明が解決しようとする課題】上記のごとき真空二重
容器に所定温度の内容物を収納して長時間に及ぶとその
内容物の温度が次第に低下することは免れない。When the contents at a predetermined temperature are stored in a vacuum double container as described above, the temperature of the contents is inevitably reduced gradually over a long period of time.
【0004】この場合、その内容物をヒーターを用いて
再加熱しようとすると、真空二重容器では、内外容器が
真空層で断熱されているため、外容器側から内容物を加
熱することはできない。このため、内容器の内部にヒー
ターを投入して加熱するしかない。In this case, if the contents are to be reheated using a heater, the contents cannot be heated from the outer container side in the vacuum double container because the inner and outer containers are insulated by a vacuum layer. . For this reason, there is no other choice but to put a heater inside the inner container to heat it.
【0005】しかし、ヒーターの投入を予定して真空二
重容器を製作すると、内容器口部に装着された栓にヒー
ターのリード線を通す必要があるので、栓の構造が複雑
になり、また栓の開閉の際にリード線と共にヒーターが
栓に付随するという不便が生じる。[0005] However, when a vacuum double container is manufactured with the heater being charged, the lead wire of the heater must be passed through the stopper attached to the inner opening of the inner container, which complicates the structure of the stopper. The inconvenience that the heater is attached to the plug together with the lead wire when opening and closing the plug occurs.
【0006】また、栓は従来構造のままとし、容器の底
からヒーターを挿入する方法も考えられるが、この場合
でもリード線を挿通した栓のまわりで内容器と外容器と
を接続しなければならず、いずれにしても構成が複雑に
なると共に、保温性能も低下する。It is also conceivable to insert the heater from the bottom of the container while keeping the stopper in the conventional structure, but even in this case, the inner container and the outer container must be connected around the stopper through which the lead wire has been inserted. However, in any case, the configuration becomes complicated and the heat retention performance is reduced.
【0007】そこで、この発明は金属製断熱二重容器の
構造を複雑にすることなく、内容物を効果的に加熱する
方法及びその加熱に適した金属製断熱二重容器を提供す
ることを目的とする。Accordingly, an object of the present invention is to provide a method for effectively heating the contents without complicating the structure of the metal insulated double container and a metal insulated double container suitable for the heating. And
