[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat insulation container for cooking which has an inner container for storing cooked food in an outer container having a vacuum double wall and which holds the cooked food in the inner container for a long time in a heat-retaining state. It is a thing.

[0002]

2. Description of the Related Art Conventionally, a heat-insulating container for cooking is provided with a single-walled inner container made of a metal material such as stainless steel for storing cooked food, and a metal material such as stainless steel is provided on the opposite left and right outer walls of the inner container. The handle for connecting the handle is screwed or welded, and the handle for the inner container is attached to the tip of the connector for the handle, while an outer container having a vacuum double wall made of a metal material such as stainless steel surrounding the inner container is provided. A flange part is provided at the mouth of the vacuum double wall with the end part of the vacuum double wall expanded outward, an annular shoulder member is attached to the lower part of the flange part, and handles for outer containers are provided on the opposite left and right outer walls of the shoulder member. At the same time, the inner lid was attached to the mouth of the inner container, the inner container handle was placed on the upper portion of the outer container handle, and then the lid was detachably attached to the outer container mouth.

[0003]

However, in this type of heat-insulating container for cooking, the inner container handle is placed on the upper part of the outer container handle with the handle connection part of the inner container and the flange part of the outer container joined together. However, a gap is provided between the inner container and the outer container so that they do not come into contact with each other, and the heat of the cooked food in the heated or cooled inner container is not released. There is a problem that the heat retaining effect is very poor because the heat in the inner container is released to the outside of the outer container along the flange portion of the outer container which is in contact therewith.

The present invention has been made to solve the above problems, and an object thereof is to provide a heat insulating container for cooking which is excellent in heat retention effect.

[0005]

In order to achieve the above object, in the heat insulating container for cooking according to the present invention, the fitting for fitting the outer container and the inner container in which the outer container and the inner container are overlapped with each other. The fitting protrusion and the fitting groove are provided, and the inner container is held in a suspended state in the outer container only by joining the fitting protrusion and the fitting groove.

[0016]

As described above, in the heat insulating container for cooking of the present invention, the outer container handle and the inner container handle in which the outer container and the inner container are overlapped with each other are fitted with the fitting projections. Since the inner container is held in a suspended state in the outer container only by joining the fitting protrusion and the fitting groove, the metal portion forming the outer container and the inner container are formed. Since there is no contact with the metal part and only the resin parts with poor heat conduction contact each other, the heat dissipation of the cooked food in the inner container is shielded, and the heat retaining effect is very excellent. Further, the fitting projection and the fitting groove are fitted to each other so that positioning can be performed, so that the set state of the inner container is always stable. Furthermore, since a space is always provided between the inner container and the outer container, the inner surface of the outer container or the outer surface of the inner container is not contaminated by contact scratches. Furthermore, since the state in which the outer container and the inner container are set can be held outside the outer container, the inner container can be made sufficiently larger than the outer container to maximize the capacity of the inner container.
