摘要

PPROBLEM TO BE SOLVED: To provide a temperature change detector for easily detecting whether or not a temperature change has occurred in an article while being simply and inexpensively manufactured, and to provide a temperature change reader and a temperature change management system for transported articles. PSOLUTION: Two kinds of liquid insoluble in each other and different in specific gravity, such as water 12 and oil 13, are sealed within a transparent container 11 to form a temperature change detection cell 10. The detection cell 10 is frozen and invertedly placed on a frozen article A. By observing whether the position of water (ice) 12 and that of oil 13 within the transparent container 11 have changed places with each other after storing or transporting the article, it can be easily known whether the temperature of the frozen article A has risen or not. Further, two frozen temperature change detection cells 10 are side-by-side placed on the article so that the position of water 12 and that of oil 13 are inverted to form this temperature change detector. By observing whether the position of water 12 and that of oil 13 are in the same positional relation after storing or transporting the article, it can be easily known whether temperature has risen or not.

要解决的问题：提供一种温度变化检测器，该温度变化检测器用于在简单且廉价地制造的同时容易地检测物品中是否发生了温度变化，并且提供了一种用于运输的温度变化读取器和温度变化管理系统文章。

解决方案：将彼此不溶且比重不同的两种液体（例如水12和油13）密封在透明容器11内，以形成温度变化检测单元10。将检测单元10冷冻并冷冻。将透明容器11内的水（冰）12的位置和油13的位置在储存或运输后是否相互改变，从而可以容易地知道温度是多少。冷冻物品A的数量是否升高。此外，两个冷冻的温度变化检测单元10并排放置在物品上，使得水12和油13的位置倒置以形成该温度变化检测器。通过观察在储存或运输物品之后水12的位置与油13的位置是否处于相同的位置关系，可以容易地知道温度是否升高。
