Abstract
Disclosed are plastic preforms and containers in which the materials in the neck, neck finish and/or neck cylinder are at least partially in the crystalline state and the body is primarily in the amorphous or semi-crystalline state. This structure in a preform enables the preform to be easily blow molded by virtue of the amorphous material in the body, while maintaining dimensional stability in hot-fill applications. In addition, the amorphous inner surface of the neck finish stabilizes the post mold dimensions allowing closer molding tolerances than other crystallizing processes. The crystallized outer surface of the preform supports the amorphous structure during high temperature filling of the container. Physical properties are also enhanced as a result of this unique crystalline/amorphous structure.
