Room temperature phase transition system thermal equilibrium type cold insulation means

摘要

PROBLEM TO BE SOLVED: To provide a cold insulation means for keeping cold at a temperature exceeding 0 ° C. and lower than 36 ° C. SOLUTION: The phase transition type thermal equilibrium type cold insulation means of the present invention includes a cold insulation agent having a melting point of a predetermined temperature exceeding 0 ° C. and lower than 36 ° C., and a flexible container for sealing the cold insulation agent. The cold insulating agent is sealed in the flexible container, and a cold insulating means capable of maintaining the temperature near the phase transition is constructed by the persistence of the thermal equilibrium state at the time of the phase transition from the solid phase to the liquid phase at the melting point. It is characterized by having a pocket-shaped mounting means that can be mounted on the axillary portion of clothing or the like and into which the above-mentioned cold insulation means can be inserted.
