Method and device for filling a container to be filled with a filling product

A method for filling a container to be filled with a filling product, comprising:

• accommodating the container in a treatment chamber;
• sealing a filling device to the container;
• subsequent to the sealing of the filling device to the container, rinsing the container with a rinsing gas introduced into the container through a rinsing gas channel;
• subsequent to the rinsing of the container with the rinsing gas, filling the container with the filling product;
• pre-pressurizing the treatment chamber with a pressurization gas through a pressurization gas channel, wherein the pressurization gas channel is distinct from the rinsing gas channel;
• subsequent to the filling of the container and the pre-pressurization of the treatment chamber, removing the filling device from the container;
• subsequent to the removal of the filling device from the container, closing the container with a container closure;
• and
• subsequent to the closing of the container, relieving the pre-pressurization pressure in the treatment chamber and removing the container from the treatment chamber,
• wherein the pre-pressurization pressure that is present in the treatment chamber is at least in part relieved into the rinsing gas channel.
