(Prior art) Some conventional electronic jars are known in which the lead wire to the lid heater is guided from the heat insulating container body side to the lid body side through a space formed in the hinge device. Conventional electronic jars have a problem in that the lead wires move within the hinge device during assembly, making it time-consuming to dispose of the lead wires.

In addition, in this type of electronic jar, while the lid heater is energized, the bottom surface of the lid is heated, so that the internal steam does not condense on the bottom surface of the lid.
When the electricity supply to the lid heater is interrupted, the lid is cooled and the steam inside the lid is condensed on the lower surface of the lid. In such conventional electronic jars, when the lid is pivoted open, the condensed water that has condensed on the bottom surface of the lid flows downward and falls onto the hinge device, and is electrically connected to the hinge device. There was a problem in that the wire could flow into the main body through the lead wire insertion gap or the joint of the hinge device.

(Purpose of the invention) In view of the above-mentioned problems with the conventional heat insulating container (electronic jar), the present invention has been developed so that the lead wires to electrical components such as the lid heater, which are led to the lid side through the hinge device during assembly, are To provide a heat insulating container having a structure that prevents movement within a hinge device and prevents dew condensed water condensed on the lower surface of a lid from flowing into a heat insulating container main body from a hinge device when the lid is opened. The purpose is to

(Structure of the invention) The invention is constructed by connecting a lid body equipped with electrical components such as a lid heater and a heat insulation container body equipped with a power terminal with a shaft between a lid side hinge member and a body side hinge member. While being pivotally connected by a hinge device, a plurality of lead wires for electrically connecting the power terminal on the heat insulation container main body side and the electrical components on the lid side are passed through the main body side hinge member and inserted into the lid side. In the heat insulating container, a concave part recessed outward is formed in the center part of the main body side hinge member excluding both sides, and a pair of lead wires for the lead wires are formed on both sides forming the concave part. Each of the lead wires is fixed in each lead wire insertion convex part as an insertion convex part, and the concave part is located directly below a condensed water dripping position where condensed water condensed on the lower surface of the lid body drips when the lid body is opened. It is characterized by the fact that
