PROBLEM TO BE SOLVED: To realize adjustment of an angle inclination of a pouch according to a heating condition.SOLUTION: A packaging box according to an aspect of the present invention is a flat packaging box having a steam port near an upper part for storing a pouch to be heated in a microwave oven. The packaging box is opened to be separated into a main body part and a rid part. The main body part holds the pouch when the pouch is heated in the microwave oven. The rid part is connected to the main body part with a hinge part at a back plate side region. The rid part is folded along the hinge part and in contact with the back plate side region of the main body part to support the main body part. In addition, the main body part is configured to deform in a height direction when the pouch is heated in the microwave oven to expand in the height direction. By virtue of the deformation, inclination for holding the pouch can be increased. |
