Patent number: 7753221Abstract: A blow-molded container is provided, which has a low blow ratio and good appearances with no flash line, glossy spot, and/or color spot on the sidewall of the container near the bottom. The mold created for this purpose is used in blow molding and is characterized in that a split mold has a mold parting face perpendicular to the mold-clamping direction, splits into front and rear mold halves, and has a mold pinch-off section, which is used to pinch off parison P and is provided with pinch-off blades on bottom surface of mold cavity bottom. In the cross-sectional plan view of said split mold in its closed state, a bottom parting line is formed by a linear pinch-off line, which is formed on the bottom surface by the pinch-off blades, a pair of mold parting lines formed by said mold parting face on the right and left peripheries, and a pair of connecting lines that connects the right and left ends of said pinch-off line with the inner ends of said right and left mold parting lines.Type: GrantFiled: October 29, 2003Date of Patent: July 13, 2010Assignee: Yoshino Kogyosho Co., Ltd.Inventors: Hiroaki Tokuda, Kazuhisa Innami
