Abstract: Packaging apparatus, such as a tray sealer, with a gas supply arrangement enabling a flushing gas to be conducted between a flushing gas outlet (26) and a flushing gas inlet (14) which are relatively moveable. The flushing gas inlet is positioned above the flushing gas outlet. The gas supply arrangement includes a barrel 15 connected to the inlet (14) and sliding in a sleeve connected to the outlet (26). In a first predetermined relative position of the flushing gas outlet and flushing gas inlet a fluid flow connection is established between the flushing gas outlet and flushing gas inlet. In a second predetermined relative position the flushing gas inlet and flushing gas outlet are disconnected and liquid may drain from the barrel 15.
