<p><P>PROBLEM TO BE SOLVED: To provide a method of manufacturing a cylindrical container for a body fluid treating device by an injection molding in which flash does not occur or falls into an allowable range if occurs even when a pair of inner molds of a butting type are used, to provide a high quality and practical cylindrical container for the body fluid treating device having no flash on the center inner surface, and to provide a hollow yarn membrane type body fluid treating device provided with the cylindrical container. <P>SOLUTION: In the method, by which the cylindrical container 1 for the body fluid treating device is formed by forming a cylindrical molding part 41 of an outer mold 11 of an injection molding mold 10 and a pair of the inner molds 21, 31 inserted into the outer mold 11, and injecting a synthetic resin into the molding part 41, a butting position A, where the end faces 21a, 31a of a pair of the inner molds 21, 31 are butted, is within a range 1/4 long of the total length of the molding part 41 from one end of the container and the injection molding is carried out by engaging the end faces 21a, 31a of the inner molds 21, 31 with each other at the butting position A. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
