It is generally configured to include 1, a spout 22, and a handle 23.

In order to heat and heat the object W to be heated using the kettle, first, the object W to be heated is placed in the main body 10.
After pouring in, heat is applied from the bottom surface portion of the main body 10 or the like, and heating is stopped when the object W to be heated reaches a predetermined temperature.

[0005]

By the way, the object W to be heated which has been once heated to a predetermined temperature using the kettle described above.
Also, heat is taken to the outside via the wall surface 11 of the main body 10 and the temperature drops. In particular, when the main body 10 of the kettle is made of a material having a high thermal conductivity (for example, copper) in order to improve the easiness of heating, the object W to be heated in the main body 10 can be cooled more easily.

After heating, if the main body 10 of the kettle is placed directly on, for example, a sink without pulling the insole or the like,
Heat escapes even through the sink, and the object W to be heated becomes easier to cool. Therefore, it is often necessary to reheat the object to be heated W each time it is used, which is complicated and uneconomical.

Therefore, in order to eliminate the above-mentioned drawbacks,
It is conceivable to increase the thickness of the wall surface 11 of the kettle body 10 to make it difficult for heat to escape. However, in this case, the kettle becomes heavy and the handleability deteriorates.
There is an inconvenience that it becomes difficult to heat.

In view of the above circumstances, an object of the present invention is to efficiently heat an object to be heated such as water contained in the main body without deteriorating the handleability, and it is effective regardless of the mounting place.
It is to provide a heating container that can keep warm efficiently .

An embodiment of the present invention will be described with reference to the drawings.
As shown in FIGS. 1 to 4, the heating container according to the present invention (the kettle in this embodiment) includes a main body 10, a tray 19 for keeping heat,
The lid 21, the spout 22 and the handle 23 are included. The same components as those shown in FIG. 5 are designated by the same reference numerals, and the description thereof will be omitted or simplified.

Here, the main body 10 has at least a wall surface 11.
The part has a double wall structure with an air layer in the middle.
In this embodiment, only the wall surface 11 of the main body 10 has a double wall structure in consideration of thermal efficiency and workability.
That is, the wall surface 11 of the main body 10 is formed such that an air layer A (heat conductivity of air; 0.02 kcal / mh ° C.) having a predetermined thickness is formed between the inner wall surface 12 and the inner wall surface 12. The inner wall surface 12 and the outer wall surface 13 are provided at a predetermined distance. The inner wall surface 12 and the outer wall surface 13 are made of the same or different materials (different materials in this embodiment).

Specifically, the inner wall surface 12 (and the bottom surface portion 14) of the main body 10 has a high thermal conductivity of copper (heat conductivity; 332 kcal / mh ° C.) in order to improve the heating easiness.
Is formed. In addition, the outer wall surface 13 of the main body 10 is
In order to improve heat retention, stainless steel (heat conductivity; 1
4 kcal / mh ° C.). As the material for forming the main body 10 and the like, various materials such as metal materials (stainless steel, aluminum, copper, etc.), pottery, enameled metal materials and the like can be cited.

In the lower portion of the main body 10, a support portion 15 having an opening 16 and a predetermined distance H from the bottom surface portion 14 in contact with a liquid or solid object (water in this embodiment) W to be heated.
