PROBLEM TO BE SOLVED: To provide a bag body for a medical drainage recovery container, where the occurrence of a pin hole in the bag body caused by a protrusion of a hard plastic cover body is prevented, the edge of the bag body is prevented from being cut at the fused portion of the bag body and the hard plastic cover body, and productivity and economy are excellent, by improving the pinking strength and tensile strength of a lamination sheet configuring the bag are improved.SOLUTION: The medical drainage recovery container is composed of: the soft plastic bag body comprising a nearly circular bottom and a nearly cylindrical trunk having an open upper end and the hard plastic cover body which is fitted into the upper end of the bag body and fixed at an outer periphery. The bag body is composed of a trunk member and a bottom member each composed of the laminate sheet obtained by laminating in order: an outer layer made of thermobonding resin, a support substrate layer made of a thermally shrinking film, and an inner layer made of thermobonding resin. A fused edge formed by bending the lower end periphery of the nearly cylindrical trunk toward the inside of the bag body and the outer periphery end edge of the nearly circular bottom member are fused to form the bottom.COPYRIGHT: (C)2012,JPO&INPIT【課題】 袋体を構成する積層体シートの突刺し強度、引張強度を向上させ、硬質プラスチック製の蓋体の突起による袋体のピンホール発生を防ぎ、袋体と硬質プラスチック製の蓋体との溶着部分で袋体がエッジ切れすることを防止すると共に、生産性、経済性に優れた医療排液回収容器用袋体を提供する。【解決手段】 略円形の底部と上端を開口した略円筒状の胴部とからなる軟質プラスチック製の袋体と、該袋体の上端に嵌入され外周縁で固着される硬質プラスチック製の蓋体とからなる医療排液回収容器において、袋体が熱接着性樹脂からなる外層と熱収縮性を有するフィルムからなる支持基材層と熱接着性樹脂からなる内層とが順に積層された積層体シートからなる胴部材と底部材で構成され、略円筒状の胴部の下端周縁を袋体の内側に折曲形成した溶着縁と略円形の底部材の外周端縁とを溶着して底部と成すものである。【選択図】 図1
