PROBLEM TO BE SOLVED: To provide a dual-cell drug bag sealing body and its wrapper preventing the opening with a diaphragm section uncommunicated and, even if moving in an outer bag, preventing the formation of a pinhole in the outer bag.SOLUTION: This dual-cell drug bag sealing body is provided with: a dual-cell liquid medicine bag 10 consisting of a bag body 11 formed by connecting two liquid medicine storage cells 12a and 12b storing different liquid medicines respectively via a diaphragm section 13b capable of communicating them to each other, and an injection plug 14 installed on one liquid medicine storage cell 12a in the bag body 11 and a bag-shaped sealing material 20 for covering the liquid medicine storage cell 12a installed with the injection plug 14 in the dual-cell liquid medicine bag 10 from the side of the injection plug 14, thermally contracting it and sealing it. The sealing material 20 extends over the diaphragm section 13b to cover an opposite drug storage cell 12b by 10 mm or more, so that only the diaphragm section 13b and sections corresponding to its peripheral sections are thermally contracted and its opening end is deformed while pushing the drug storage cell 12b having a little shape retaining property in the width direction.COPYRIGHT: (C)2009,JPO&INPIT【課題】隔壁部を開通させない状態では開封することができず、しかも、外装袋内で動いても、外装袋にピンホールが発生しにくい複槽薬剤バッグ封緘体及びその包装体を提供する。【解決手段】異なる薬液がそれぞれ収容された二つの薬液収容室12a、12bを相互に連通可能な隔壁部13bを介して連結してなるバッグ本体11と、このバック本体11における一方の薬液収容室12aに装着された注出用口栓14とからなる二槽薬液バッグ10と、この二槽薬液バッグ10における注出用口栓14が装着された薬液収容室12aに、注出用口栓14側から被せて加熱収縮させることによって封緘する袋状の封緘材20とを備えている。封緘材20は、隔壁部13bを越えて、反対側の薬剤収容室12bを10mm以上覆っており、隔壁部13b及びその周辺部に対応する部分だけが熱収縮し、その開口端は、保形性の乏しい薬剤収容室12bを幅方向に押えて変形させている。【選択図】 図1
