ABSTRACT:
A filling device for sterile filling of containers. A flexible temporary storage container is placed in a dosage chamber and exposed to external over-pressure and under-pressure, respectively. The filling goods is sucked into the temporary storage container and pressed out to the final storage container. A device for fine adjustment of the volume of the chamber has the shape of an adjustable membrane. The temporary storage container can be made of two semi-spheres, of which one is rigid and the other flexible. The flexible part forms a membrane having an area equal to the inner area of the rigid semi-sphere. In order to promote natural rolling of the membrane on the inner surface of the rigid semi-sphere, the membrane has reduced wall thickness in a direction towards the margin thereof.
