PURPOSE:To simplify a member for announcing an abnormal temp. rise and to reduce the cost thereof by sealing an odorous material into an enclosure which melts down to rupture when the temp. rises abnormally and evaporating the odorous material to emit an alarm when the temp. rises abnormally. CONSTITUTION:The odorous material consisting of, for example, ester or the like which has odorousness and has no inflammability is sealed into a microcapsule 1 consisting of, for example, gelatin, etc. The capsules are stuck to the surface of a base 2 consisting of a sheet such as paper and an adhesive sheet 3 is stuck to the rear thereof to constitute a label 7. The label 7 is adhered to an object A of which the temp. is likely to arise abnormally. The heat of the object A is conducted through the adhesive sheet 3 and the base 2 to the capsules 1 when the temp. of the object A rises abnormally. The odorous material diffuses into the air and announces the abnormality when the shell of the capsules 1 is heated up to the melting temp. |
