Abstract
A method for filling a plastics container, wherein an excess pressure is built up in the filled and closed container. The method includes the following method steps: filling the plastics container with a liquid, and closing the filled plastics container. In a deformation step, the container, prior to being closed, is deformed by a mechanical force such that the cross-sectional shape of the container is changed and its volume is thereby increased. In a pressure relief step, the mechanical force is removed once the container has been closed, as a result of which the volume contraction causes an excess pressure to build up in the container, and the filling height of the liquid increases.
