Abstract
A filling method includes executing a pre-stressing phase, during which, at plural time intervals, gas is drawn from a gas space that lies above the filling material in a tank. The gas pre-stresses a container up to a second pressure that is below the pressure in the gas space. During a filling phase, a liquid valve opens to allow the filling material in the tank to enter into the container. This valve is above the level of the filling material, thus preventing gravity from driving the flow.
