Claims

[Scope of utility model registration request]

In a metal thermos consisting of a vacuum double container, in which a metal inner container and a metal outer container are integrally joined at their mouths, and the gap between the inner and outer containers is a vacuum insulated space, on the circumference of the neck of the outer container and Ribs extending along the circumference are formed on the inner circumference of the cap, and these ribs are engaged with each other to fit the cap to the mouth and neck of the vacuum double container, and also to fit the cap to the top of the outer container. A recess or a convex part is provided at a position different from the rib on the neck including the part, and a locking part that engages the recess or the convex part is provided on the inner periphery of the mouthpiece so that they engage with each other. A metal thermos flask characterized in that a spout surrounds the mouth of an outer container and is fixed to be integrated with the neck.
