[Action]

 In the containers 1 and 11 of the present invention, the air permeability of the containers 1 and 11 is adjusted according to the type of the food F to be stored prior to the microwave heating of the food F. The ventilation is adjusted between the ventilation holes 4, 14a, 14b and the valve body 5 by changing the insertion depth of the valve body 5 into the ventilation holes 4, 14a, 14b of the lids 3, 13. This is done by adjusting the cross-sectional area of the ventilation channel. As the insertion depth of the valve body 5 into the ventilation holes 4, 14a, 14b is made shallower, the cross-sectional area of the ventilation passage becomes larger. The high temperature steam or hot air generated by the microwave heating of the food F is discharged to the outside of the containers 1 and 11 through the ventilation passage between the ventilation holes 4, 14a and 14b and the valve body 5. Therefore, the insides of the containers 1 and 11 do not become abnormally high temperature, high pressure, and high humidity, and deformation of the containers 1 and 11, abnormal heating of the food F, and deterioration of flavor due to stuffiness are avoided. When the temperature is kept after heating, the valve body 5 is pushed to the deepest part into the vent holes 4, 14a, 14b, and the collar part 7 closes the vent holes 4, 14a, 14b.
