Abstract:
1. A method for producing a filled pump arrangement comprising the steps of: (a) filling a product capable of flow into a film bag accommodated in a container having at least one feed channel; and (b) closing the film bag and the container using a manually-activated pump to block a fluid connection between an outlet opening and an interior portion of the bag using at least one kick-back valve in an unstressed state; wherein the at least one feed channel remains open in the container after the container has been closed by the pump for introduction of a fluid under pressure through the at least one feed channel into the container in order to compress the film bag in the container and eject from the film bag gases through the pump or through a bypass channel circumventing the pump; and wherein the at least one feed channel remains open in order to permit pressure equalization between the interior of the container and the surroundings while the film bag is being emptied.
