초록 ▼

A radially expandable core pin is disclosed for blow-molding a thermoplastic container having a body-portion and a neck-portion, with such neck-portion including a dispensing orifice and internal attachment means. The core pin is radially expandable to compression mold the internal attachment means of the container and comprises a plurality of circumferentially disposed core sections surrounding the central axis of the core pin. These core sections are radially movable between a normally collapsed position and an expanded position, and have outer surfaces which mate along their longitudinal adjacent sides when radially displaced to expanded position to form a substantially continuous neck-forming surface thereabout. The neck-forming surface is relieved in a predetermined pattern to form the internal attachment means of the container. The core pin also includes expansion means for moving the core sections to expanded position, and blowing means formed through the core pin and adapted to be connected to a pressure source. The blowing means provides blow-molding pressure for forming the body portion of the thermoplastic container.
