Title:
PREFORM HAVING INTEGRAL HANDLE
Document Type and Number:
WIPO Patent Application WO/2023/229120
Kind Code:
A1
Abstract:
The present invention relates to a preform having an integral handle, comprising: a preform having an overall "U" shape in which the shape of an inlet of a PET container is integrally formed with an inlet hole configured such that a stretch rod can be inserted thereinto; and a handle, formed integrally with the preform, having a fixing piece so that the handle can be drawn into the PET container to be molded when the preform is stretched by the stretch rod. Since the handle is integrally formed with the PET container when injecting the basic preform for molding the PET container, the process of coupling the handle is omitted, and thus the manufacturing process is simplified. In addition, since the PET container and the handle are made of the same material and the preform is stretched by means of the stretch rod to bind the fixing piece when the PET container is molded, durability is enhanced.
