PREFORM AND CONTAINER

摘要

An injection-molded preform for manufacturing plastic containers, for example plastic bottles, in a stretch blow molding process is disclosed. The preform can have an essentially elongated preform body, whose one longitudinal end is formed closed. On an opposite longitudinal end, the preform body is connected to a neck section that is provided with a pour opening and whose outer wall has a connector to make an interlocking connection with a closure that is equipped with corresponding engagement. The neck section has at least one bottleneck that extends all the way around and has a wall thickness of between 0.4 mm and 0.8 mm. The injection-molded plastic material exists at least on the at least one bottleneck in a state that is highly oriented and at least partially crystalline, due to an injection-molding process.

1. An injection-molded preform for manufacturing plastic containers, in a stretch blow molding process, the injection molded preform comprising:
an elongated preform body including one longitudinal end formed closed; and another longitudinal end, lying opposite the one longitudinal end, connected to a neck section provided with a pour opening and on whose outer wall is formed a connector for making an interlocking connection with a closure equipped with corresponding connector, wherein the neck section has at least one bottleneck that extends all the way around the neck section at least in places and has a wall thickness of 0.4 mm to 0.8 mm, and the injection-molded plastic material exists on the at least one bottleneck in a state that is highly oriented and at least partially crystalline, due to an injection-molding process.
