(I) a fold defining a folding plane and a first peripheral edge of the pouch； (ii) a first side crossing the folding plane； and (iii) a second opposite the first side and crossing the folding plane. A pouch provided with a film including the side surface of the pouch. The pouch fixture includes a port and a base. The base portion includes an intermediate portion that engages with the fold in the folding plane, a first side portion that is located on one side of the intermediate portion, and a second portion that is located on the opposite side of the intermediate portion with respect to the first side portion. A side of the head. The first and second sides of the base cross the folding plane and engage the first and second sides of the film, respectively. The base or film overlaps the other to define an overlap region. The base and film are sealed together in the overlap region to form a liquid tight seal that extends around the port.（ｉ）パウチの折り畳み平面および第１の周縁部を画定する折り目と、（ｉｉ）折り畳み平面を横切る第１の側面と、（ｉｉｉ）第１の側面の反対にあり、折り畳み平面を横切る第２の側面とを含むフィルムを備えるパウチである。パウチの取付具は、ポートと基部とを含む。基部は、折り畳み平面で折り目と係合する中間部と、中間部の一方の側に位置する第１の側部と、第１の側部に対して中間部の反対の側に位置する第２の側部とを画定する。基部の第１および第２の側部は、折り畳み平面を横切り、フィルムの第１および第２の側面とそれぞれ係合している。基部またはフィルムは、他方に重なって重なり領域を画定する。基部およびフィルムは、重なり領域内で互いにシールされ、ポートを囲んで延在する液密シールを形成する。
