A plastic container and a method for producing a plastic container for liquids comprising an outer jacket made of latticework or of sheet metal material and a pallet-type understructure, the plastic container including a blow-molded body having a container socket in a container wall, the container socket provided with a container opening and connected to a flange of the container fitting via a welded joint, wherein the container wall has an inner layer made of a first plastic material and an outer layer made of a second plastic material, and the container socket has a longitudinal cross section widening toward the container opening such that an end face of the container socket 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 is formed by the inner layer segment.

Plastic container for fluids and method for producing a plastic container

A lid (1) is injection-molded of polyethylene, for a widemouthed barrel of a synthetic resin, and includes an outer rim (4) encompassing the barrel neck (3) and an inner rim (5) dipping into the barrel neck. The outer lid rim (4) and inner lid rim (5) form an annular space (7), an annular web (8) projecting axially from the base of this space. For producing the lid gasket (13), the annular space (7) is exposed to an open flame for activating the annular space surface. Subsequently the sealing material, preferably polyurethane, is injected from a foaming machine into the base of the annular space (7), and thereafter the lid (1) is vibrated in order to degasify the gasket (13). The sealing material, preferably consisting of foamed polyurethane, contains a parting compound having a long-term effect.
