When the capacity of the container is 1000 ml, 320 ° C or higher, 500 ml
And 250 ml, the temperature is 280 ° C. or higher, and it can be understood that hydrogen peroxide can be sufficiently removed from the inside of the container by blowing pressurized hot air having a temperature equal to or higher than the predetermined temperature according to the capacity of the packaging container 3. This is because the hydrogen peroxide-containing solution adhering to the inside of the container is heated and decomposed by the hot compressed air blown inside the container to generate water and oxygen, and the water content after decomposition is It is mainly due to the fact that it can vaporize quickly. In addition, 500 ml and 250 ml
And the both have the same predetermined temperature as 280 ° C. or higher because the average flow rate of the hydrogen peroxide-containing solution applied to the inside of the container is 250 ml less than 500 ml (2/2 /
This is because it is set 3 times).
