Aseptic filling and sealing of packages with a food product is carried out in compartments which contain an atmosphere of sterile air and which contain devices for filling and sealing packages and a transporter device for transporting the packages through the compartments for the filling and sealing operations. Headspace sterile air is removed and displaced from the packages by injection of nitrogen into the packages from a nozzle which is at a fixed position and which directs the nitrogen at an angle with reference to a vertical perpendicular to the horizontal package transport direction and counter to the transport direction.

[ We claim:] [3.] In a process for aseptically filling packages with a product wherein compartments contain an atmosphere of sterile air and wherein packages are transported through the compartments for filling and sealing, first filling a transported package with a product, wherein the package filled contains headspace sterile air, and transporting the filled package horizontally to a nozzle positioned for injecting nitrogen gas between two movable sealing elements and at atmosphere pressure and room temperature, injecting sterile nitrogen gas from the nozzle into package headspace and between the sealing elements for displacing headspace sterile air and moving the movable sealing elements together for sealing the package sealing elements, the improvements comprising:ejecting the sterile nitrogen gas from a nozzle maintained in a fixed position and so that the gas is injected into the package headspace in a direction at an angle to a vertical perpendicular of and counter to the horizontal direction of package travel to displace sterile headspace air with the sterile nitrogen gas and sealing the package so that the sealed package contains the sterile nitrogen gas.
