Abstract

Disclosed is an apparatus for expanding and filling plastic parisons to form plastic containers with a liquid medium, with at least one transforming station which has a hollow mould, inside which the plastic parisons can be expanded into plastic containers and can be simultaneously filled by application of a liquid medium, wherein the transforming station is arranged on a carrier and wherein the transforming station has a filling device which feeds the liquid medium to the plastic parisons under pressure, wherein the transforming station has a pressure chamber to which a gas can be applied, wherein for filling of the plastic parisons the filling device can be introduced into the pressure chamber and after the filling can be removed at least partially, and wherein a closing unit can be introduced into the pressure chamber, in order to close the expanded und filled plastic containers.
