ABSTRACT OF THE DISCLOSURE Method for producing a container whose interior is substantially under atmospheric pressure, by means of a vacuum welding process in which the container is sealed by welding together under vacuum a plurality of wall components while maintaining an opening therein. The interior of the container is filled through the opening with a medium which is substantially under atmospheric pressure. The opening is made vacuum-tight by means of a first sealing means. The container interior is sealed from the outside by an additional seal in the form of a cover for the opening, which cover is welded to the container under vacuum. The cover borders on the outer face of the container in such a manner that the cover is welded to the container under vacuum along a line which extends at such a distance from the first sealing means that the sealing effect of the first sealing means is not adversely influenced.
