<p><P>PROBLEM TO BE SOLVED: To solve the problem with difficulty in uniformly controlling the thickness of resin as a whole and forming a complicated structure, when forming a hollow structure using a blow molding method. <P>SOLUTION: A composite structure is formed by injection-molding an alkali-resistant resin on the peripheral surface of a core body made of an injection-molded polyglycolic acid resin so as to be adhered and to coat the peripheral surface. The resin-made hollow body is formed by immersing the composite structure in an alkaline solution and eluting the core body. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
