【発明の詳細な説明】 ＜産業上の利用分野＞ 本発明は液体紙容器の殺菌方法に関し、特に液体紙容
器の内面を殺菌する殺菌方法に関する。Description: TECHNICAL FIELD The present invention relates to a method for sterilizing a liquid paper container, and more particularly to a method for sterilizing an inner surface of a liquid paper container.
＜従来技術＞ 耐熱菌（例えば、枯草菌、ステアロサーモフィラス）

く、又、加熱ムラによって殺菌効果がばらつく。<Prior art> Heat-resistant bacteria (for example, Bacillus subtilis, Stearothermophilus)
For sterilization such as H 2 O 2 (Hydrogen peroxide) to apply a disinfectant, but H 2 O 2 etc. will have no effect unless heated above a certain temperature and used, generally H 2 O 2 Dip the object to be sterilized (container, etc.) in a heating bath, or spray H 2 O 2 , then heat it with hot air to enhance the sterilizing effect and dry H 2 O 2 to prevent residue The method is adopted. In the case of heating with hot air alone, since heating is performed at a high temperature because there is no heat capacity, the carton is partially heated and easily damaged, and the sterilization effect varies due to uneven heating.

を多くして殺菌効果を安定せざるをえなかった。Therefore, a method of increasing the sterilizing effect by heating with hot air after spraying H 2 O 2 is employed, and drying is performed at the same time. However, due to heating with air only, due to the structure of the equipment that has a small heat capacity, use multiple stations, take up space for the equipment, and if it is heated rapidly to a high temperature, it is difficult to heat the entire surface evenly and part of the carton Can be damaged by heat. Also, the sterilization effect tends to be uneven due to uneven heat. In particular, it is said that when H 2 O 2 is heated rapidly, vapor deposition occurs before the sterilizing effect increases, so that the sterilizing effect decreases. In particular, in the case of a container formed of one blank sheet such as a liquid paper container or the like, a folded portion, a bonding portion, and the like are present on the inner surface thereof, and the inner surface is provided with a synthetic resin layer such as polyethylene. Bad wetness,
Application of the disinfectant was likely to be uneven, and the disinfecting effect had to be stabilized by rapidly spraying to increase the application amount.
＜発明が解決しようとする問題点＞ 本発明は上記した問題点を解決するためになされたも
