Mould filling with subsequent closing under internal pressure

An apparatus for expanding and filling plastic parisons to form plastic containers with a beverage, with at least one transforming station which has a hollow mould, inside which the plastic parisons are expanded into plastic containers and simultaneously filled by application of the beverage through a mouthpiece of the plastic parison, wherein the transforming station is arranged on a carrier and wherein the transforming station has a filling device configured to feed the beverage to the plastic parisons under pressure, wherein the transforming station has a pressure chamber to which a gas is applied, wherein for filling of the plastic parisons the filling device is introduced into the pressure chamber and after the filling is removed at least partially, and wherein a closing unit is introduced into the pressure chamber, in order to close the expanded and filled plastic containers, wherein

• the plastic containers are beverage containers and wherein a main body of the plastic parison or the plastic container is located in the hollow mould and the mouthpiece is located inside the pressure chamber, and a container closure is introduced at ambient pressure into the pressure chamber, before the pressure is raised, and wherein
• the closing unit is configured to be withdrawn completely from the pressure chamber, and the closing unit, when completely withdrawn from the pressure chamber, is configured to receive a container closure outside the pressure chamber.
