PROBLEM TO BE SOLVED: To provide a urine collection bag, the opening of which can be easily opened.SOLUTION: The urine collection bag 11 has a longitudinal direction Y, a transverse direction X and a depth direction Z, and is configured from a plurality of sheets (39, 40, 41, 42, 44, 45, 49) formed of thermoplastic synthetic resin. The urine collection bag 11 is formed in a bag shape with an opening 28 that extends in the transverse direction X and provides therein a urine-collecting space S that communicates with the opening 28. In the urine collection bag 11, rigid parts 80, which are formed by heat-sealing the plurality of sheets (39, 40, 41, 42, 44, 45, 49), are formed only at the two edges (30c, 30d) of the plurality of sheets (39, 40, 41, 42, 44, 45, 49) in the transverse direction X that are a part of a rim 28a of the opening 28. The rigid parts 80 are formed so as to be continuous in the depth direction Z from one surface to the other surface.COPYRIGHT: (C)2013,JPO&INPIT【課題】開口を容易に開くことができる尿収容袋を提供する。【解決手段】尿収容袋11は、縦方向Yと横方向Xと厚さ方向Zとを有し、熱可塑性合成樹脂で形成された複数枚のシート39,40,41,42,44,45,49で構成してある。尿収容袋11は、横方向Xに延びる開口28を有して開口28に通じる尿収容空間Sを内部に備える袋状に形成してある。尿収容袋11には、複数枚のシート39,40,41,42,44,45,49を熱融着することで形成した高剛性部80を開口28の周縁部28aの一部であって、シート39,40,41,42,44,45,49の横方向Xにおける両側縁30c,30dのみに形成してある。高剛性部80は、厚さ方向Zにおける一方の表面から別のもう一方の表面まで連続するように形成してある。【選択図】図11
