PROBLEM TO BE SOLVED: To provide an easy-to-use transfer set which can be easily fixed on a vial or the other medical container, is relatively inexpensive, and has a simple structure.SOLUTION: An assembly 20 of a tightly-sealed container and a transfer set includes: a first container 22 having a diameter reduced neck part 30 that is adjacent to a rim part 28 enclosing an open end a stopper 32 arranged on the open end of the first container and a fluid transfer set 40 which is mounted on the open end of the first container for transferring a fluid between the first container and a second container. The fluid transfer set includes: a first tubular collar part 46 which is permanently deformed radially into the diameter reduced neck part of the first container for retaining the transfer set on the first container a second tubular part 50 integrated with a radial part 48 a third tubular part 52 which tightly engages with the stopper and is aligned to be approximately coaxial with the second tubular part a piercing member 42 received in a nested manner in the third tubular part and a removable plug 44 for closing a free end 57 of the second tubular part and an opposite free end of the third tubular part.COPYRIGHT: (C)2015,JPO&INPIT【課題】バイアルまたは他の医療用容器に容易に固定され得て、比較的安価で、構造が単純であり、使い易い移送セットを提供する。【解決手段】密封容器と移送セットのアセンブリ20であって、開放端を囲むリム部28に隣接する縮径ネック部30を有する第1の容器22と、第1の容器の開放端に配置されるストッパ32と、第1の容器の開放端に装着され、第1の容器と第2の容器との間で流体を移送する流体移送セット40であって、第1の容器の縮径ネック部へと径方向に永久変形させられ、第1の容器上に保持する第1の管状カラー部46と径方向部分48と、一体になった第2の管状部50と、ストッパと密に係合する、第2の管状部と概ね同軸になるように整列される第3の管状部52と、第3の管状部内に入れ子状に受け入れられる穿刺部材42と、第2の管状部の自由端57および第3の管状部の反対側の自由端を閉じる取り外し可能な栓44をを備える。【選択図】図2
