<p><P>PROBLEM TO BE SOLVED: To provide a container with a blow ratio reduced by a direct blow molding method in which the formation of a cut-off trace by a split mold for blow molding is limited to the bottom surface of the bottom part and to provide a novel blow-molded container excellent in appearance. <P>SOLUTION: The container is obtained by the direct blow molding method. In the container, a cylindrical barrel part is formed above the bottom part, and a cylindrical spout is formed above the barrel part. The cut-off trace by the split mold for blow molding is formed only in the bottom surface of the bottom part. The minimum diameter of the spout is equal to or slightly larger than the outside diameter of a parison formed in the container by blow molding, and the width of the cut-off trace formed in the bottom surface of the bottom part is smaller than 1.6 times of the outside diameter of the parison. <P>COPYRIGHT: (C)2004,JPO</p> |
