Beschreibung
Zusammenfassung:	A dispensing device comprising a flexible inner container having a valve unit for dispensing a filling substance present in the inner container and an outer container sealingly engaged with the inner container. Pressurized gas present in an intermediate space between the outer and inner containers is used to generate an expulsion force for discharging the filling substance. To simplify manufacturing and make lower quantities economically feasible to manufacture, while also increasing the metering accuracy of the discharge of the filling substance the intermediate space is connected to an external pressurized gas source.
