ABSTRACT:
A method of making a plastic container having a body and a finish with at least one external thread includes injection or compression molding a plastic preform having a body and a finish with at least one external thread, blow molding the body of the preform to form the body of the container, and either prior to, subsequent to or both prior and subsequent to blow molding the container body, expanding the injection or compression molded preform finish to form a container finish having at least one injection or compression molded external thread. In the preferred embodiments of the invention, the finish is expanded after the container body is blow-molded. The invention can be implemented to expand a narrow-neck preform or container finish to a wide-mouth preform or container finish.
