[Problems to be solved by the invention] In the prior art,
Because the knob of the inner lid is undulating, when you pick this knob, you must first raise this knob,
Further, there is a problem that the inner lid is not stable in a state where the knob is pinched, and the handleability of the inner lid is poor. In addition, since the finger touches the inner lid when the pick is made, there is a risk of burning when the inner lid is hot.

Therefore, in order to improve the handleability and safety of the inner lid, it is conceivable to stand the knob with the knob fixed on the upper surface of the inner lid. A problem arises in that the height of the entire insulated cooker is increased. On the other hand, if the entire heat insulating outer lid is made thinner by the height of the knob, the heat insulating performance is reduced.

When the cooking pot is stored in the heat-insulating container, it is placed on the inner bottom surface of the heat-insulating container, and the curved outer bottom edge of the cooking pot is curved inside the heat-insulating container. Because it is configured to be supported in contact with the, the storage state of the cooking pot in the insulated container becomes unstable, for example,
When handling the insulated cooker in a state where the cooking pot containing the object to be cooked is stored in the heat insulating container, there is a possibility that the contents may flow out due to rattling of the cooking pot and tilting. In addition, the contact between the outer bottom edge of the cooking pot and the inner bottom edge of the heat-insulating container may be caused by shocks when placing the cooking pot on the inner bottom surface of the heat-insulating container or vibrations when handling the heat-insulating cooker. There is a problem in that the bumps collide with each other and dents and scratches occur near the contact portion between the outer bottom edge of the cooking pot and the inner bottom edge of the heat insulating container. Furthermore, since the bottom edge of the outer surface of the cooking pot and the bottom edge of the inner surface of the heat insulating container are in contact with each other, heat can be easily conducted from the cooking pot to the heat insulating container or from the heat insulating container to the cooking pot via this contact portion. However, there is a problem that the heat retention and the cold retention performance are reduced.

The present invention is intended to solve such a problem, and the inner lid can be easily and safely handled.
Further, it is an object of the present invention to provide an easy-to-use heat-insulating cooker that can reduce the height of the entire heat-insulating cooker and has excellent heat-insulating performance.
