Abstract

The invention concerns a fuel container of plastic material such as a motor vehicle fuel tank, having one or more welded seams as seam locations for the body of the container and/or as connecting or sealing seams between the container wall in the region of openings and closure elements or covers welded thereto. At least some of the welded seams are at least partially penetrated by a duct which extends in the longitudinal direction in the seam and which can be filled with air and vented.
