REFRIGERATOR

PROBLEM TO BE SOLVED: To maintain the antibacterial constitution concentration in a container constantly and to obtain a high antibacterial effect including air and food surface by arranging a sustained release film for discharging an antibacterial constituent made of olefin resin at a volatile antibacterial material at a part where a cool air passes in a refrigerator. SOLUTION: A sustained release film 12 for discharging an antibacterial constituent made of olefin resin at a volatile antibacterial material 1 at a point where a cool air passes inside a refrigerator. Then, an antibacterial constituent particle 11 is impregnated with a gel-shaped substance 2. Also, the amount of sustained release of the antibacterial constituent is increased against the temperature increase in a container due to the opening/closing of the door by the sustained release film made of a shape memory resin due to temperature, thus dispersing the antibacterial constituent into the refrigerator and constantly maintaining the antibacterial constituent concentration in the container, killing germs floating in air and germs being adhered to the surface of food, and hence achieving a high antibacterial effect.
