PLASTIC BOTTLE WITH HANDLE AT ITS NECK

摘要

PROBLEM TO BE SOLVED: To provide a superior handle formed by an injection molding having a superior durability by a method wherein a bending strength and a flexibility of the hanger integrally molded with a neck are applied by stretch orientation. SOLUTION: This is a bottle formed by a blow molding in which a hanger 5 is integrally formed in an upward direction at a lower side surface of a neck 2 when a pre-form of crystalline resin is injection molded. A location 52 connected to the side surface of the neck 2 of the handle 5 is formed at a thin- walled bending section 52a made by tensioning and extension. Both a bending strength and flexibility are applied to the handle 5 in response to the extension and elongation of the bending section 52a and the handle 5 can be bent in an upward or downward direction.
