Injection molded preform for producing a plastic container in a blow process, plastic containers produced therefrom and production methods for the preform or the plastic container.

摘要

The invention relates to an injection - molded preform for producing a plastic container in a blow process, which comprises an elongated, tubular preform body (2), one longitudinal end of which is closed and a neck portion (4) with a pouring opening at the other longitudinal end. The neck section (4) is connected by spraying to a functional part (10), which is likewise produced by means of an injection-molding process. The functional part (10) has an annularly shaped section (7) with an inner wall (71), which rests directly against an outer surface (61) of the neck section (4), and an annularly closed area (6) of the outer surface (61) of the neck section (4) completely.
