Abstract: At the step of preheating the container, in addition to heating of the whole container, a neck portion (1a) of the container may be heated separately. Alternatively on the step of preheating the container, while whole container is heated by a hot air blast which is supplied in the container, neck portion (1a) of the container may be heated separately. Since it is difficult to increase the temperature of the neck portion as compared with other portions, by heating the neck portion separately, the effect of the preheating is performed more effectively. It is desirable that the hot air blast is supplied from the nozzle inserted in the container. For example by the method of spraying hot air blast from the outside of the portions, heating of the neck portions can be performed.

Abstract: Opposite sides of an article are irradiated to sterilize the article. The cumulative irradiation should be above a first value, and below a second value greater than the first value, at all of the positions in the article to provide the article with desired radiation benefits. Any amount of cumulative radiation between the first and second values is considered as optimal values. For a first range of article thicknesses, the cumulative radiation in the article is at the optimal values. For article thicknesses in a second range greater than in the first range, the cumulative radiation at positions in the article is greater than the optimal values. For article thicknesses in a third range greater than the second range, the cumulative radiation at the different positions in the article is at the optimal values. For the thicknesses in the second range, a member disposed in the radiation path weakens the radiation passing to the article, thereby reducing the cumulative radiation to an optimal value.
