Multi-container filling machine technologies

An apparatus for filling containers with fluid, the apparatus comprising:

• a rotary filling station, wherein at least one fluid container is filled with a fluid in the rotary filing station;
• a rotary gassing station comprising:
• a single rotary wheel having a top plate and bottom plate, wherein the single rotary wheel is positioned at an immediate exit of the rotary filling station, wherein the single rotary wheel of the rotary gassing station is rotationally interfacing with the rotary filling station such that the fluid containers exiting the rotary filling station transfer directly from the rotary filling station to the rotary gassing station;
• a fluid container movable directly from the rotary filling station to the single rotary wheel of the rotary gassing station wherein the top plate is positioned at least partially above an opening of the fluid container;
• at least one gassing channel for supplying a quantity of carbon dioxide (CO2) gas to a headspace of the fluid container, wherein the at least one gassing channel is positioned at least partially through the top plate;
• and
• a lid supplied from a lid delivery chute to an upper portion of the top plate of the single rotary wheel, wherein the lid is held by the upper portion of the top plate in a position directly above an opening of the fluid container during rotation of the single rotary wheel, wherein an exit of the at least one gassing channel is positioned proximate to the headspace of the fluid container and between the opening of the fluid container and the lid, and, wherein after supplying the quantity of CO2 as to the headspace of the fluid container, the lid is moved downward through the upper plate and positioned on the opening of the fluid container.
