<p>PROBLEM TO BE SOLVED: To easily realize deodorizing, anti-fungal and heat insulation properties when fresh fishes, shellfishes, meats, flowers, etc., are carried by making cooling, deodorizing, anti-fungal and heat insulating properties based on chemicals possible by using chem. reactions of the chemicals. SOLUTION: In a heat insulating box provided with a lid A and a main body B, a gas-permeable partition plate C is provided on the back side of the lid A and a chem. agent D (a heat insulating agent) is stored in the space divided with this partition plate C. As the chem. agent D, for cooling, e.g. ammonium nitrate-urea is used and for deodorizing and anti-fungal functions, an extract powder of a plant mixed with a polymer powder is used and they are used as a embodiment wherein these chem. are sealed in a paper fiber bag. When it is used, the chem. with the bag are immersed into water. In addition, a check valve is fitted on the side face and air in the box is properly exhausted by opening this check valve so as to bring cool air into uniform contact with carried articles. In addition, to hold cooling effect for a long time, sealability is improved by applying an adhesive tape, etc., on the bonded part between the main body B and the lid A.</p> |
