ABSTRACT:
A method for producing a blow molded, heat set container including at least one large collapse panel in a side wall of the container. The area of the side wall of the container forming a collapse panel is heat set at a lower temperature than the area of the side wall of the container adjacent to the collapse panel to prevent distortion of the large collapse panel when the container is removed from a mold.
