Plastic container for liquids and method for producing a plastic container

Abstract

A plastic container (10) and a method for producing a plastic container for liquids, in particular an inner container for transport and storage containers for liquids comprising an outer jacket made of latticework or of sheet metal material and a pallet type understructure, the plastic container (10) being realized as a blow-molded body by blow molding from a tubular preform in a blow mold and having a container socket (17) for connecting a container fitting (18) in a fitting connecting area (16) of a container wall (13), the container socket (17) being provided with a container opening and being connected to a connecting flange (21) of the container fitting (18) via a welded joint (52), wherein the container wall (13) has an inner layer made of a first plastic material and an outer layer made of a second plastic material, and the container socket (17) has a longitudinal cross section widening toward the container opening in such a manner that an end face of the container socket (17) is formed at least in part by an inner layer segment disposed opposite the outer layer, and a welding contact surface of the container socket (17) is formed by the inner layer segment.
