- 摘要：
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 surface of the cup 1 is performed by blowing mist or gas (a) or b of hydrogen peroxide toward the inner and outer faces of the cup made of PET, a hot air c is blown toward the inner and outer faces of the cup so as not to deform the cup to dry hydrogen peroxide sticking to at least the inner face of the cup. Until the inner face of the cup is sterilized to a required extent, hydrogen peroxide is stayed in the cup, and just after it, blowing of the hot air is started, and a plurality of times of the blowing of the hot air are performed until the remaining amount of hydrogen peroxide on at least the inner face of the cup falls within an allowable range, and the cup is cooled to a required temperature by placing a cooling time from the preceding blowing of the hot air to the next blowing of the hot air.
