Abstract
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. The all or those portions of said connecting lines that lie adjacent to said pinch-off line are formed by end parting faces located at right and left ends of the pinch-off section of said split mold so that a pair of roughly right-angled bent corners is formed by all or those adjacent portions of said connecting lines and said pinch-off line.
