Description
Technical Field
[0001] The utility model relates to the technical field of bottle preforms, in particular to a bottle preform with a lightweight bottle body. Background Art
[0002] Bottle preforms are products produced by injection molding and are intermediates before blow molding into various bottles. Under specific temperature and pressure, the raw materials are filled into the mold to form semi-finished products with specific shapes and sizes. These bottle preforms are then processed by blow molding and eventually become common plastic bottles, cosmetic bottles and other containers in our daily lives.
[0003] The bottle preform is mainly composed of three parts: the bottle body, the bottle mouth and the bottle bottom. The bottle mouth is provided with threads and limit rings. During blow molding, the bottle body and the bottle bottom are placed inside the blow molding machine, and the bottle mouth is placed outside the blow molding machine. The thickness of large-volume bottle preforms is generally 5 to 5.5 mm.
[0004] Nowadays, most preforms have smooth surfaces on both sides of the bottle body, simple structure, and no lightweight structure. The bottle body uses more materials, the production cost of the preform cannot be reduced, and the weight of the bottle after blow molding is relatively large. Utility Model Content
