The seal section has an outer edge seal part that is positioned along an outer edge of the bag, and a steam-releasing seal part that is positioned closer to a center point side of the storage section than the outer edge seal part and peels off due to an increase in pressure in the storage section. The steam-releasing seal part peels off when the pressure in the storage section is 130 kPa or lower.
