Bottle with carrying handle

摘要

A biaxially stretched bottle (1) made of a thermoplastic resin having a carrying handle (6) formed by integrally injection molding on the side of a lower neck portion (2) of a preform (10) at the same time when the preform (10) is molded and applied as-formed as a carrying handle (6) of a thin-wall bottle formed by stretch blow molding, wherein the carrying handle (6) is formed with its arm portions (62) extending across the both sides of the neck portion (2), enabled to rotate up and down with respective joining portions of base portions (7) and the arm portion (62) which are formed in symmetrical positions on both sides of the neck portion (2) as its axis. This enables the change in the position of a gripping portion (61), which has been difficult in conventional integral forming, even in a bottle made of a material resin like PET resin which lacks in flexibility.
