外容器側に放出され易くなる。(Prior art) In recent years, liquid containers made of stainless steel plates and having a vacuum-insulated double wall structure have become popular. Compared to the commonly used glass vacuum-insulated double-bottle bottles, the heat retention ability will be lower.
That is, in a metal heat-insulating double container, over time gas is released from inside the metal material into the space between the double walls, the degree of vacuum in the space decreases, and the radiant heat from the wall of the inner container is released into the space. It becomes easy to be released to the outer container side through the gas inside the chamber.

空間部５４内へ放出されるという問題がある。 However, in this known metal heat-insulating double container, the plating layer 60 is formed from the bottom to the vicinity of the mouth on the outer surface of the inner container 52, but it extends from the mouth 52a of the inner container 52 to a depth a. reachable range T
Since no plating layer is formed on the inner container 52, there is a problem in that radiant heat is released into the space 54 from the wall surface of the portion of the inner container 52 where the plating layer is not formed.

いる。(Example) An example of the present invention will be described with reference to FIGS. 1 and 2. The metal insulated double container of this example is similar to the inner container 2 made of stainless steel with low thermal conductivity. The outer container 3 made of stainless steel is joined to each other by a predetermined height range A at the respective mouths 2a and 3a (joint part 5), and the upper end of the joint part 5 is welded (welded part 6). Both inner and outer containers 2, 3
In addition, a plating layer is provided on the outer surface of the inner container 2 to prevent radiant heat from dissipating from the wall surface of the inner container 2. 10.

されている。 Plating layer 10 formed on the outer surface of the inner container 2
is formed in the entire area including the bottom and side circumferential portions of the inner container 2 as well as the mouth joints 5 of both the inner and outer containers 2 and 3 (excluding the welded portions 6). That is, in this embodiment, the opening joint portion 5 of both the inner and outer containers 2 and 3 is
The height range A (Fig. 2) of The height C is approximately 0.6 mm, and the inner container 2
A plating layer 10 is formed on the entire outer surface except for the height B range (approximately 1 mm height range).

器２と外容器３の接合部上端部を溶接する際に、
該メツキ層１０が溶接の支障になることがない。 Furthermore, since the plating layer 10 is not formed at least in the height range C that forms the welding part 6, when welding the upper end of the joint between the inner container 2 and the outer container 3,
The plating layer 10 does not interfere with welding.
尚、この実施例では、内容器２の外面だけしか

ておくこともできる。 In this embodiment, the plating layer 10 is formed only on the outer surface of the inner container 2, but in other embodiments, the plating layer can be similarly formed on the inner surface of the outer container 3. When plating layers are formed on the outer surface of the inner container 2 and the inner surface of the outer container 3 in this way,
Space 4 from inside the material of the inner container 2 and outer container 3
can prevent gas from being released into the
The degree of vacuum within the space 4 does not decrease over a long period of time. In other embodiments, the space 4 may be
A getter material can also be sealed inside to prevent a decrease in the degree of vacuum.

なることがない。(Effect of the invention) The metal heat-insulating double container of the present invention has a plating layer 10 formed on the outer surface of the inner container 2 in an area that reaches the inside of the mouth joint 5. 58-12680), the radiant heat released from the wall surface of the inner container 2 into the space 4 between the double walls can be reduced as much as possible, and the heat retention ability can be improved. It has the effect of being able to. Furthermore, even if the plating layer 10 is formed on the outer surface of the inner container 2 as widely as possible, the plating layer is not formed on the portions that will become the mouth welds 6 of both the inner and outer containers 2 and 3. Since there is no such container, both the inner and outer containers 2 and 3
There is no problem when welding at each mouth portion 2a, 3a.
