<P>PROBLEM TO BE SOLVED: To provide a synthetic-resin multiple container that allows an inner container to be surely gripped so as to allow a molded product to be extracted from a die when molding an outer container, and a manufacturing method for the same. <P>SOLUTION: The synthetic-resin multiple container includes an injection-molded inner container (2) and an outer container (3) integrally injection-molded on the outer surface of the inner container (2) to be configured to form a locked part (13), where the inner container (2) is locked to the core-side die, on the inner container (2) when the outer container (3) is injection-molded to the inner container (2). Accordingly, the inner container (2) is allowed to be held in the core-side die, and also, the locked part (13) to the core-side die (15), thereby preventing the inner container (2) from falling off from the core-side die even if resistance occurs between the outer container (3) and the cavity-side die. <P>COPYRIGHT: (C)2012,JPO&INPIT |
