POROUS MEMBRANE CARTRIDGE AND ITS MANUFACTURING PROCESS

摘要

PROBLEM TO BE SOLVED: To prevent a liquid from entering the side part of a porous membrane in a cartridge holding the porous membrane. SOLUTION: The porous membrane cartridge 1 has a tubular barrel 40 with an outer circumferential face constituting a barrel side fused part 42 at one end side, a tubular cap having a cap side fused part 23 externally in contact with the barrel side fused part 42 and a holding face to be brought into contact with an opening end part 42b of the barrel side fused part 42 for holding the porous membrane 30 between the holding face and the barrel 40 and the porous membrane 30 held between the the opening end part 42b of the part 42 and the holding face of the cap 20. The shape of barrel 40 is molded by inserting the cap 20 and the porous membrane 30 into the cavity and injecting the molding material into the cavity. The relationship (H/D) between the height (H) and the outer diameter (D) of the cap side fused part 23 is≥0.07. COPYRIGHT: (C)2006,JPO&NCIPI
