Abstract
The invention relates to a method and to a device for the production of at least one container filled with a medium, said container being made of a plastic material. The plastic material is extruded in a tubular manner and is applied to the inner walls of a moulding tool in order to mould the respective container by means of differential pressure. The respective container is filled with a medium via the inlet opening with the aid of a filling device and the inlet opening of the container is closed by a lock. A coextrusion method is used for the extrusion of different plastic materials, whereby the respective container is made at least partially of several layers of plastic materials. At least one of the layers is used at a barrier layer.
