TOOL, APPARATUS, AND METHOD FOR REFORMING A TRIMMED FINISH PORTION OF A PLASTIC CONTAINER

摘要

A tool, an apparatus, and a method are provided for reforming a portion of a plastic container such as, for example, a trimmed neck finish end portion of an extrusion blow molded plastic container, after molding and trimming, to eliminate or reduce sharp edges on an inner end surface of the finish end portion. The tool includes a heated portion, a substantially unheated portion, and an insulating portion disposed between the heated portion and the unheated portion. The heated portion has a higher temperature than the unheated portion and is configured to contact and heat the finish portion to at least a glass transition temperature of the plastic container. The unheated portion is also configured to contact the finish portion of the container. The tool is tapered along a longitudinal axis defined by the tool.
