PROBLEM TO BE SOLVED: To decrease the amount of remaining hydrogen peroxide on the inner face of a cup without bringing about thermal deformation on the cup made of polyethylene terephthalate (PET).
SOLUTION: After sterilizing treatment of the cup is performed by blowing mist or gas (a) or b of hydrogen peroxide toward the inner and outer faces of the cup 1 made of PET, hot air c and d are blown toward the inner and outer faces of the cup so as not to deform, to dry the hydrogen peroxide sticking to at least the inner face. Before the mist of the hydrogen peroxide is blown, mist of water is blown on the inner face of the cup. After the hydrogen peroxide is allowed to stay in the cup until the inner face of the cup is sterilized to a required extent, blowing of the hot air is immediately started. The hot air c blown to the inner face of the cup is made to such a high temperature that the remaining amount of the hydrogen peroxide on the inner face can be decreased and the sterilization can be performed to a required extent, and the hot air d blown on the outer face is made to such a low temperature that the outer face can be sterilized to a required extent.
