本考案はステンレス等の金属で真空二重容器を
構成してなる金属製魔法瓶に関する。[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a metal thermos flask having a vacuum double container made of metal such as stainless steel.
（従来技術）
従来の金属製魔法瓶においては、前記真空二重
容器に前記肩部材を取り付ける構造として、次の
３種類のものがある。(Prior Art) In conventional metal thermos flasks, there are the following three types of structures for attaching the shoulder member to the vacuum double container.
第１のものは、前記真空二重容器の外筒部外周
に環状の突条を一体形成し、ここに肩部材を無理
嵌めし、且つその無理嵌めが金属と合成樹脂とに

め部に接着剤を塗布する構造である。しかし、こ
の構造によれば、接着剤の接着強度にバラツキが
あり、肩部材の真空二重容器に対する取り付けが
不安定となる。 The first method is to integrally form an annular protrusion on the outer periphery of the outer cylindrical part of the vacuum double container, and force the shoulder member to fit therein, and the force fit is made of relatively rigid metal and synthetic resin. In order to compensate for the fact that the height of the shoulder member does not allow for sufficient fitting, adhesive is applied to the forced fit between the protrusion and the shoulder member. However, with this structure, the adhesive strength of the adhesive varies, making attachment of the shoulder member to the vacuum double container unstable.
第２のものは、前記突条に代えて、前記外筒部
外周に雄ネジを一体形成した構造である。しか
し、この構造によれば、前記雄ネジがプレス成形
されるため、ネジ山の高さや形状に限界があり、
肩部材の保持力が不十分であるという問題があ
る。 The second one has a structure in which a male screw is integrally formed on the outer periphery of the outer cylindrical portion in place of the protrusion. However, according to this structure, since the male thread is press-formed, there are limits to the height and shape of the thread.
There is a problem that the holding force of the shoulder member is insufficient.
第３のものは、前記真空二重容器の外筒部に取

の複雑化を招くという問題がある。 The third type has a structure in which a fitting is welded to the outer cylindrical portion of the vacuum double container, and a shoulder member is screwed to the fitting. However, this structure has the problem of increasing the number of parts and complicating the installation work.
以上のように従来のものは、肩部材の真空二重
容器への取り付けが不安定となつたり、その取り
付け作業が煩雑になるという問題を抱えている。 As described above, the conventional devices have problems in that the attachment of the shoulder member to the vacuum double container becomes unstable and the attachment work becomes complicated.
又上記従来例のいずれもが、肩部材の外筒部を
真空二重容器の外筒部に取り付けた構造としてい
