20130156067 | TEMPERATURE MANAGEMENT MEMBER UNDER REDUCED-PRESSURE ATMOSPHERE AND TEMPERATURE MANAGEMENT METHOD UNDER REDUCED-PRESSURE ATMOSPHERE - A temperature management member under a reduced-pressure atmosphere, wherein the difference in the discoloration temperature of a temperature-sensitive discoloration layer between under an atmospheric pressure atmosphere and under a reduced-pressure atmosphere can be minimized. A temperature management member under a reduced-pressure atmosphere includes a temperature-sensitive discoloration layer which contains granular or powdery hot-melt matter that melts at a melting temperature corresponding to a heating temperature to be detected under a reduced-pressure atmosphere and which is discolored in response to the hot melting thereof, and a difference in the melting temperature of the hot-melt matter within the temperature-sensitive discoloration layer between under an atmospheric pressure atmosphere and under the reduced-pressure atmosphere is 5° C. at most. | 06-20-2013 |
