Abstract: To improve the moldability and keeping cold performance of a vacuum heat insulating container. A constant temperature container includes a heat insulating container formed by disposing a core material between an outer cover material and an inner cover material and sealing the core material in a reduced-pressure state. The core material includes a first core material, the first core material being an organic substance made of open-cell foam, and a second core material having a lower thermal conductivity than the first core material at a vacuum degree of 100 Pa or less.

Abstract: An inspection device (12) for a cold insulator (10) includes: an RF reader 50 that receives from an RF tag 30 a detected temperature of a cold insulator in a cold insulation box, the detected temperature being detected by a temperature sensor (20) attached to a surface of the cold insulator; and a controller 61. The controller outputs information indicating a result of comparison between: at least one of a lower limit temperature obtained by adding a predetermined first value to a lowest management temperature of an article that is kept cold in the cold insulation box and an upper limit temperature obtained by subtracting a predetermined second value from a solidification temperature of the cold insulator; and the detected temperature of the cold insulator which has been received by the RF reader.
