[0004]

[Problems to be solved by the device]

 However, in the conventional heat-insulated cooker, only one inner pan for cooking can be stored in the heat-insulated container, so the number of dishes is limited to one. In addition, even if the capacity of the heat-insulating container is increased to accommodate multiple cooking pots, the contents will spill if the lid of the cooking pot cannot be fixed to the pot body. Furthermore, when the handle of the inner cooking pot is not protruding from the upper edge of the inner cooking pot when it is stored in the heat-insulating container, the inner cooking pot is difficult to remove, but the handle is the inner cooking pot. If more than one cooking pan is stacked, the handle will tilt the upper cooking pan due to the handle and the stability will be poor and the contents will spill if more than one cooking pan is stacked.

Therefore, the present invention can fix the lid of the inner cooking pot to the main body of the pan even when the inner cooking pots are housed in the heat-insulating container, and also when the inner cooking pots are stacked. , The purpose is to provide an insulated cooker in which the upper cooking pot does not tilt due to the handle.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, according to the present invention, an inner cooking pot in which a lid is attached to a pan body with a handle is put into and taken out of an insulated outer container consisting of an outer lid having heat insulation and an outer container body. In a heat-insulating cooker that can be stored freely, the inner pot for cooking has a lid whose peripheral edge covers the upper edge of the opening of the main body of the pot, and a knob whose height is the same as or slightly protrudes from the peripheral edge of the lid. And the handle is formed to be slightly larger than the outer diameter of the opening of the pan body, and the handle is rotatably attached to the opposite side walls of the pan body via mounting brackets, and is attached to at least one of the mounting brackets. When the handle is laid down, it is held in a state of slightly protruding from the peripheral edge of the lid, and when the handle is pressed from above, a rotation restricting piece that makes the handle at the same height as the peripheral edge of the lid is provided, A plurality of inner cooking pots are housed in the heat-insulating outer container, and the inner surface of the outer lid It is characterized by pressing and holding the lid of the cooking in a pot.
