INTERNAL TEMPERATURE DISPLAYING DEVICE FOR COLD INSULATED CONTAINER FITTED WITH INTERNAL TEMPERATURE SENSOR OF COLD INSULATED CONTAINER

摘要

PROBLEM TO BE SOLVED: To solve the problem in a conventional device in capable of displaying measurement showing that food in a cold insulated container is kept at a temperature not higher than the reservation temperature stipulated by the Food Sanitation Act by displaying the temperature throughout reservation.;SOLUTION: Substances having different linear expansion coefficients are combined into a temperature sensor with the expansion coefficients of the substances set against each other. Showing temperatures by using this allows food in the cold insulated container to be dealt in lawfully in the eye of the Food Sanitation Act.;COPYRIGHT: (C)2001,JPO
