PROBLEM TO BE SOLVED: To provide a sterilization bag which facilitates sterilization treatment, facilitates the storing of material to be sterilized and the taking-out of the material after sterilization, permits sanitary maintenance even after the taking-out of the material and can be used for various forms of material to be sterilized including sharp form and slender form.SOLUTION: A sterilization bag comprises a rectangular non-air permeable sheet body 2 made by laminating a resin layer 2B having heat-sealability and easy peeling performance onto a substrate layer 2A and a rectangular air permeable sheet body 3 which is impervious to bacteria and has heat-sealability. Onto the inner surface side of a folded body formed by folding opposite edges 4A, 4B of the non-air permeable sheet body 2 such that the resin layer 2B gets to the inner side and the opposite edges 4A, 4B are separated from each other to form an air permeable part A, the air permeable sheet body 3 is joined so as to cover the air permeable part A by heat seal to form a tubular body and, at the same time, the opposite edge 4B is made to be such a knob part D that the opposite edge 4B can be pinched from the outside and the opening part 5A of the tubular body is sealed by heat seal 8.COPYRIGHT: (C)2015,JPO&INPIT【課題】滅菌処理し易く、被滅菌物を収納して滅菌した後に取り出し易く、取り出し後も衛生に保ち易く、尖った形態や細長い形態を含む多様な形態の被滅菌物に対しても使用できる滅菌用袋を提供する。【解決手段】基材層2Aにヒートシール性且つイージーピール性を有する樹脂層2Bを積層した、矩形状の非通気性シート体2と、菌を通さなく且つヒートシール性を有する、矩形状の通気性シート体3とからなり、非通気性シート体2の対辺4A,4Bを樹脂層2Bが内側になり且つ対辺4A,4B間を離間させて通気部Aを形成するように折り曲げて形成された折曲体の内面側に、通気部Aを塞ぐように通気性シート体3をヒートシールにより接合して筒状体とするとともに、対辺4Bを外方から摘むことができる摘み部Dとし、前記筒状体の開口部5Aをヒートシール8で封止した。【選択図】図1
