Zusammenfassung:	A seal pin assembly for a forming and filling head configured to inject a product into a thermoplastic preform for simultaneously forming a container from the thermoplastic preform and filling the container with the product. The seal pin assembly includes a seal pin movable within the forming and filling head towards and away from a nozzle of the forming and filling head. The nozzle is configured to cooperate with the thermoplastic preform. A vortex generating member is mounted to the seal pin and configured to convert a stream of the product into a vortex as the product flows across the vortex generating member and out through the nozzle.
