ABSTRACT:
An aseptic system and filling head wherein the container is presterilized and has a rupturable membrane over the inlet which membrane is broken by the filling machine prior to filling. The membrane may be a laminate which is broken by pressure of the product with which the container is to be filled. In that case the outermost layer of the laminate is dissolved prior to the filling step to weaken the membrane. Alternatively the membrane may be pierced by a reciprocating tool which also functions as a valve member in the filling head or by a fixed blade arranged around the outlet nozzle of the filling head.
