As a cooking utensil suitable for this type of cooking, an insulating cooking container shown in FIG. 6 has been conventionally provided.

This heat-insulating cooking container includes an outer container 1, an inner container 2 to which an inner container lid 2a is attached, and a heat-insulating outer container lid 3.
It consists of and. The outer container 1 is an outer bottle 4 and an inner bottle 5.
With a double structure consisting of and, between the inner and outer bottles 4, 5,
A heat insulating portion 6 filled with vacuum or a heat insulating material is formed.

Outer container handles 7 projecting outward are attached to the outer sides of the opposing portions of the opening of the outer container 1, and the outer bottom portion is supported for stably placing the outer container 1. The body 8 is attached by screws 8a.

Further, the inner container 2 is provided with a handle portion 11 of the inner container 2 which is composed of a handle handle 9 and a handle 10 attached to the tip. The base end of the handle handle 9 of the handle portion 11 is fixed to the outer peripheral surface of the inner container 2, extends upward, bends outward, and abuts on the edge 12 of the opening portion of the outer container 1, The handle 10 of the container 1 extends above the handle 7, and the handle 10 has substantially the same height as the upper surface of the outer container lid 3 and the outer container lid 3
Is close to.

However, in the heat-insulated cooking container, the inside of the inner container cannot be observed while the inner container is covered. In order to see the inside of the inner container during heating or adiabatic cooking, it is necessary to open the inner container lid or the heat insulating outer container lid and the inner container lid.

In particular, when the lid is opened during the adiabatic cooking, the temperature of the inner container is lowered, the adiabatic cooking function is significantly lowered, and there is a possibility that the heat cooking is required again.

As a result of various studies to solve the above problems, the present inventors have made the inner container lid transparent, and the water vapor generated from inside the inner container condenses on the inner surface of the inner container lid, resulting in its transparency. If you do not damage the inner container lid, you can observe the inside of the inner container by opening only the outer container lid without opening the inner container lid, and if you form a viewing window on the outer container lid, It was thought that the heat loss could be reduced by observing the inside of the inner container through the transparent portion of the outer container lid.

The present invention has been made on the basis of the above idea, and provides a heat-insulating cooking container capable of observing the inside of the inner container without heat loss not only during heat cooking but also during heat insulating cooking. The purpose is to do.

[0014]

In the heat-insulating cooking container according to the present invention, an outer container having a heat insulating property, and an inner container having an inner container lid that is removably accommodated in the outer container,
In a heat-insulated cooking container consisting of a heat-insulating outer container lid that closes the opening of the outer container in a state where the covered inner container is housed, the inner container lid that closes the opening of the inner container is from the center. The problem-solving means is a heat-resistant transparent body having a convex shape that gradually descends toward the periphery or a concave shape that gradually descends from the periphery toward the center and that is composed of a part of a substantially spherical surface. By forming a metal vapor deposition film or a heat shield plate on the inner surface of the inner container lid made of the heat-resistant transparent body while leaving a part of the transparent portion, the inside can be seen and heat loss due to radiation can be suppressed. it can. Furthermore, if a viewing window is formed in a predetermined portion of the heat insulating outer container lid, the inside of the inner container can be observed through the inner container lid.

[0015]

Since the heat-insulating cooking container according to the present invention has the above-mentioned structure, the water vapor generated from the inside of the inner container is condensed on the inner surface of the inner container lid, and the transparency of the lid is lost, but the inner surface of the lid is
Since it continuously descends from the central part to the outer peripheral part or from the outer peripheral part to the central part, the condensed water flows along the inner surface of the inner container lid, flows into the inner container, and then the inner surface of the lid. The haze is removed and remains almost transparent. Therefore, if only the outer container lid is opened, the inside of the inner container can be observed through the lid of the inner container. When the outer container lid is provided with a transparent portion, the inside of the inner container can be observed without opening the lid of the inner and outer containers.

[0016]
