Abstract
The method comprises the following steps: a) the container opening is sealed, b) at least one wall opening is created by drilling through or piercing the wall of the outer container using a drill, graver or needle, a pressurized medium being introduced into the gap between the outer container and the inner tube, once the wall of the outer container has been fully penetrated, c) the advance of the drill or needle is halted as soon as a predetermined first pressure threshold has been reached in the inner tube, d) the introduction of the pressurized medium into the gap between the outer container and the inner tube is halted as soon as a predetermined second pressure threshold has been reached in the inner tube, e) once the pressure in the gap between the outer container and the inner tube has been relieved, a pressurized medium is introduced into the inner tube through the container opening, in order to place the inner tube against the container wall again after it has been detached from the latter. The method allows the inner tube to be detached in a controlled manner with a high degree of uniformity from the outer container and to be placed against said outer container again without a significant inclusion of air.
