Title: Biaxially stretched bottle having a carrying handle

Abstract: A biaxially oriented bottle having a carrying handle is provided. A carrying handle, which is provided at a side surface of a neck portion, and which is injection molded together with the neck portion of a preform, is used without further modification as the carrying handle of a biaxial stretching blow molded, thinly formed bottle. The carrying handle is integrally formed in a U-shaped configuration from a grip portion and arm portions on both ends of the grip portion. The arm portions are integrally formed with base portions comprising projected pieces formed at symmetrical positions on both sides of the neck portion. The arm portions, moreover, extend out to the sides with a length greater than the height of the neck portion. The boundary of the base portion and arm portion is thinly molded by being constricted and forms a connecting portion which can be freely bent in a vertical direction. The base portion is supported by a bracket which is integrally formed with the bottom surface of the base portion and the side surface of the neck portion.
