To provide a high temperature and high pressure sterilization of a mushroom medium which can efficiently raise the temperature inside a culture medium when carrying out high temperature and pressure sterilization, and which does not cause excessive drying of the culture medium and a bad effect accompanying a change in atmospheric pressure in the sterilization chamber Provide tools.SOLUTION: The upper opening 2 is opened so that the culture medium 8 can be put in and taken out. Both sides of the opening 2 are overlapped so that they can be hermetically sealed in a plane, the overlapping portion 1a is tilted to one side, In a bag-shaped film container 1 which can be bent downward by bypassing the high pressure which is increased by the steam boiler of the sterilization chamber and the low pressure accompanied with the exhaust, and also has a hardness such that the airway can not be narrowed, A tube 5 having a bellows portion 6 formed in an intermediate portion is sealed in a gap between the tube 5 and the overlapped portion 1a of the film container 1 and one end portion 5a is opened to the outside of the filmy container 1 And the other end portion 5 b faces the culture medium 8 and opens in a state where ventilation is possible and mounts it.(FIG.【課題】高温高圧殺菌を行うに際し、効率良く培地内の温度を上昇させることができ、又培地の過度な乾燥や殺菌室内の気圧変化に伴う弊害を発生させることのないきのこ培地の高温高圧殺菌用具を提供する。【解決手段】上部の開口部2を開いて培地8を出し入れ可能とし、該開口部2の両側を重ね合わせて平面的に密封可能とすると共に重ね合わせ部分1aを一方側に倒し、収納した培地を迂回して下向きに屈曲可能とした袋状のフィルム容器1に、殺菌室の蒸気ボイラーで高められた高圧と排気に伴う低圧との繰り返しによっても気道が狭められない硬度を備え、折り曲げ可能な蛇腹部6を中間部位に形成した管体5を、該管体5とフィルム容器1の重ね合わせ部分1aとの隙間を密封状態とし、一方端部5aを前記フィルム状容器1の外部に開口させると共に他方端部5bを培地8に臨んで通気可能な状態に開口させて装着する。【選択図】 図1
