<p><P>PROBLEM TO BE SOLVED: To provide a blow molding bottle with a synthetic resin grip in which the bottle is provided with a barrel part having a rectangular cylindrical section where an easy holding grip is integrally molded. <P>SOLUTION: This blow molding bottle 1 with a grip is made so that a cavity 6 can be formed over an entire circumference at a middle location in a vertical direction of a barrel 2 having a rectangular cylindrical section, and the cavities 61, 63 of the wide side surfaces 11a, 11b, 13a and 13b act as a grip part. The cavities 61, 63 have the deepest size at the central part in a side width direction and have the widest width. Cavity bottom surfaces 31, 33 are defined by a concave curved surface 31a and a convex curved surfaces 31b, 31c that are smoothly continuous to each other and the right and left convex curved surfaces 31b, 31c have a large curvature. A downward inclined outer peripheral surface 41 defining the upper inner side surface of the cavity 61 extends linearly in a side surface width direction. Fingers contacting the grips 61, 63 are positively engaged with both side convex curved surfaces 31b, 31c having a large curvature and a downward inclined outer circumferential surface 41 extending linearly, so that the grip facilitating a lifting-up of the bottle 1 can be attained. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
