Abstract
PURPOSE:To simplify the structure of a monitor and to attain massproduction by composing a sensor of a container, a heat sensing material, a shuttle, and a sensing member. CONSTITUTION:The temperature and time monitor consists of the container 1 which is formed partially in a tube shape, the shuttle 3 made of liquid inserted into the tube part 2 of the container 1 movably so that its cross section is closed, the heat sensing material which is charged the enclosed space 4 partitioned in the container 1 by the shutter 3, and the sensing member 5 which is exposed at a specific position of the inner peripheral surface of the tube body 2 and changes its form irreversibly and reversibly by contacting the shuttle 3 so that the progress extent of the form changing has a specific relation with the time of contacting with the shuttle 3. Here, when the tube part 2 is made transparent or translucent, the position of the shuttle 3 which is viewed from outside can be decided objectively, so a high function as a thermometer is obtained. Further, when the capacity of a heat sensing material reservoir part 5 is increased or when the internal diameter of the tube part 2 is reduced, the movement quantity of the shuttle 3 in the tube part 2 with temperature increases and the temperature and temperature resolution are increased.
