摘要： A dual-chamber container is formed in an injection blow molding process. Two preforms are injection molded around respective core rods. The preforms and core rods are then moved to a blow mold, in which the preforms are molded to the confines of the mold. The blow mold has partial walls between the two cavities, which provide directional control over the preforms as the preform wall portions are blown against and contact welded to each other. The outer walls of the preforms, which must travel and stretch a greater amount than the inner walls, are formed thicker in the preform molding operation.

摘要： Injection molding apparatus (10) for molding a thermoplastic article (A) from a moldable thermoplastic material. The molding apparatus includes a core pin (12) around which the article is formed in a cavity that is defined by separable mold halves (14, 16). Moldable thermoplastic material is introduced into the mold cavity, coaxially of the core pin, from an injection nozzle (18) through a restricted passage or gate (20). The nozzle seats solely in a radial extension (16a) of one of the mold halves, which is received in a recess (14a) of the other mold half when the mold halves are closed with respect to one another, and the gate extends solely through the extension (16a) of the mold half (16).
