れている。2. Description of the Related Art Conventionally, a vacuum insulating structure such as a thermos bottle in which a vacuum is evacuated between an inner bottle and an outer bottle made of stainless steel is inspected for its heat insulation performance in order to judge the quality of the product. ing. As a method of testing the heat retention performance, it is common to put hot water of 95 ° C. in a vacuum heat insulating structure and measure the temperature of the hot water after 24 hours. However, in this inspection method, it is necessary to prepare hot water and a long time is required for measurement. Therefore, various alternative methods have been proposed.

開示されている。[0003] For example, Japanese Patent Publication No. 42-19811 discloses that a vacuum insulated structure is placed in a heating furnace in a state where a thermistor is inserted and sealed in an inner bottle and heated, and the inside of the vacuum insulated structure is heated. A method for measuring the temperature change of the vacuum heat insulating structure with the thermistor to inspect the heat insulation performance of the vacuum heat insulating structure is disclosed.

In addition, since a heating furnace is required, the equipment becomes large and cannot be incorporated into a production line, and a large amount of electric power is required to maintain the temperature of the heated furnace, which increases energy costs. There was a problem.

が生じてしまうという問題があった。In the latter inspection method, the inside of the inner bottle is heated using heat conduction by a high-temperature gas, so that the inside of the inner bottle is kept at a high temperature for at least 2 minutes to reach a predetermined temperature required for measurement. Gas needs to be injected into the inner bottle. Therefore, there is a problem that the energy cost is increased as in the former case. In addition, since the high-temperature gas is injected into the inner bottle, it is necessary to keep the vacuum heat insulating structure in an inverted state in consideration of the convection of air, which imposes restrictions on the design of the production line. There was a problem.

It is preferable to measure the temperature of the outer bottle and determine the heat retention performance by comparing the temperature difference between the temperature and the initial temperature with a predetermined threshold value. In this way, the inspection time can be further reduced.
