A highly functional lunch box that functions as a cooling agent when frozen by sealing an ice pack inside the lid. After filling it with food, just place the lid, which has been frozen overnight in a household refrigerator, in place. By freezing the lid and using it, the lid itself acts as a cooling agent, so you can carry it around safely even on warm days.
