Abstract
In an injection blow-molding process the preform is purposely formed as a smooth walled tube closed at one end and without any thread or other cap attachment configuration about the mouth of the preform. The preform is moved to the bottle mold which completely forms the cap attachment configuration with the bottle in the blow-molding step. A processing dome is also formed from the preform in the blow-molding step to provide means to transfer the bottle to the trimmer which removes the dome. By using the smooth walled preform (without threads or any other cap fastening features), the bottle mold may utilize only a portion of the vertical height of the preform for the bottle. Bottle molds for a variety of bottle volumes and heights may employ the same preform and preform injection mold. The smooth walled preform also permits bottle molds with a variety of mouth diameters to be employed with the same preform injection mold. Since the bottle mold provides the specific cap attachment configuration of the bottle such as threads or lugs, the same preform and preform injection mold may be employed for a variety of cap attachment configurations.
