PROBLEM TO BE SOLVED: To provide a knockdown bathtub in which a cloth-shaped member is connected to a side plate and a protrusion edge part is provided in a hot water supply bag for solving the problem in which a hot water supply bag needs to be hooked with a string and connection between a standing plate and a hooking plate becomes weak in a knockdown bathtub with a constitution using a side plate and a bottom plate.SOLUTION: Portion of a hot water supply bag 1 protruding above a standing plate upper edge 46 becomes a continuous protrusion edge part 2. When a moderately hard member is used, a segment protrusion edge part 12 is constituted by cutting corners of the portion protruding above the standing plate upper edge 46. A cloth-shaped member 24 is joined to the lower part of the standing plate, the standing plate is connected so as to constitute an annular standing plate 30, a large connection standing plate 33, and a small connection standing plate, the respective plates are erected to constitute wall surfaces, and the hot water supply bag is internally provided on the wall surfaces to constitute a bathtub.COPYRIGHT: (C)2015,JPO&INPIT【課題】本発明は、組み立て浴槽には、側板と底板を用いた構成のものがあるが、給湯袋を紐で掛止する必要があり、また、立設板と掛止板の接続が弱くなる問題点があったので、側板に布形状部材を接続し、給湯袋に突縁部を設けた組み立て浴槽を提供する。【手段】給湯袋1の、立設板上縁46より上方に突出し部位が連続突縁部2となる。やや硬い部材を用いる際に、立設板上縁46より突出した部位の、角を切離して切片突縁部12として構成する。立設板下方に布形状部材24を接合し、立設板を接続して環状立設板30、連結立設板大33、連結立設板小を構成し、それぞれを立設して壁面を構成し、壁面に給湯袋を内装し、浴槽を構成する。【選択図】 図1
