PROBLEM TO BE SOLVED: To close a spout passage hole of a chamber.SOLUTION: A spout passage hole through which a spout of an inner bag of a bag-in-box passes is continuously opened from a side surface to a bottom surface on a chamber that provides contents filling rooms. When the inside of the chamber is steam-sterilized, the spout passage hole is closed by a CIP adapter 40. The CIP adapter 40 has an L-shape along front and bottom surfaces of the chamber on which the spout passage hole is opened, and is big enough to cover the entire spout passage hole. On an inner surface of the CIP adapter 40 is provided an elastic O-ring 47 which is in close contact with the front and bottom surfaces of the chamber when the CIP adapter 40 is mounted on the chamber.SELECTED DRAWING: Figure 4COPYRIGHT: (C)2020,JPO&INPIT【課題】チャンバのスパウト通過孔を閉じる。【解決手段】内容物の充填室を提供するチャンバにはバッグインボックスの内袋のスパウトが通過するスパウト通過孔が側面から底面にかけて連続してあけられている。チャンバの内部を蒸気殺菌するときに，上記スパウト通過孔はＣＩＰアダプタ40によって閉じられる。ＣＩＰアダプタ40は，スパウト通過孔があけられたチャンバの前面および底面に沿うＬ字形の形状を備え，スパウト通過孔の全体を覆う大きさを持つ。ＣＩＰアダプタ40の内面には，ＣＩＰアダプタ40がチャンバに取り付けられたときにチャンバの前面および底面に密着する弾性Ｏリング47が設けられている。【選択図】図４
