PLASTIC BOTTLE HAVING HANDLE, AND MANUFACTURING METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a plastic bottle having a handle which generates no puncture during blow molding. SOLUTION: The excessive elongation at a bottom surface of a recessed part for forming a handle is suppressed by forming right and left edge portions of a fitting inlet part in a lower handle fitting part of a bottle body in a substantially perpendicularly erected manner. The change of contact with a lower surface of the handle body in a process that an oriented resin is swollen during the blow-molding can be effectively reduced, and the ratio of generation of puncture can be effectively suppressed by forming a hill part raised from its periphery whose upper surface is abutted on a lower surface of a lower fitting arm of the handle body in the bottom surface of the recessed part for forming the handle in the bottle body.
