<p><P>PROBLEM TO BE SOLVED: To form a central depression part into which a remaining liquid of a content liquid is naturally concentrated on the center of an inner face of a bottom part by constituting the bottom part into a cone shape whose inner face is expanded downward and having a self-standing function. <P>SOLUTION: In a blow molded container made of a parison, the bottom wall 5 of the bottom part 4 is constituted into the cone shape expanded downward, and three or more leg pieces 9 are hung down into plate piece shapes on the outer face of the bottom wall 5. Three or more leg pieces 9 are arranged radially by equal central angles, and three or more pinch-off lines 10 being traces of pinching-off remaining and formed on the bottom face of the bottom part 4 are arranged radially by equal central angles under a condition that they are positioned on the undersurface of the leg pieces 9. The central depression part 7 into which the remaining liquid of the content liquid is naturally concentrated is thereby formed on the inner face of the bottom wall 5, and a stable 'seat' function is ensured. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
