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 different 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 the mold.

A method for producing a blow-molded heat set container, including at least one large panel in a side wall of said container, said method comprising: blowing-molding a parison of thermoplastic material to form said container in a mold comprising a mold cavity which defines a final shape of said container, said mold cavity having an inner wall and having at least one mold wall panel portion corresponding to said large panel to be formed in said side wall of said container; and applying heat to said mold to heat set said container, an inner surface of said mold wall panel portion being heated to a temperature sufficiently different from a temperature to which adjacent portions of said inner wall of said mold are heated to heat set said large panel at a temperature sufficiently different than remaining sections of said container to prevent distortion of said large panel when said container is removed from said mold.
