The present disclosure provides systems and methods for refilling fluid containers. A fluid container may include a bottle and a valve assembly. The valve assembly may include two valves and be configured to engage with the bottle and a filling head or dispensing head. A system is configured to provide pressurized fluid to the refillable container, monitor filling, determine when to stop filling, and determine how much fluid was provided. The valve assembly may include a float mechanism coupled to one of the valves of the valve assembly to ensure fluid flow is stopped when the fluid container is full. The fluid, which can include carbon dioxide, is stored in a storage tank. A flow system provides the fluid to a filling head, which engages with the fluid container. The flow system includes a transfer pump, valves, and sensors configured to provide the fluid to the filling head.

A method for filling and closing containers at a filling and closing unit of a handling station. After the completion of a filling phase, a handling phase is carried out at the filling and closing unit of the handling station, in which the process chamber is pre-loaded, in particular above the container opening of the corresponding container, by way of nitrogen to a pressure which is at or above the saturation pressure of the CO.sub.2 contained in the filling material.

A carbonated beverage aseptic filling system (10) comprises: a filling nozzle (72) for filling a carbonated beverage; a carbonated beverage filling tank (75) connected to the filling nozzle (72) via a carbonated beverage supplying pipe (73) and a counter pressure pipe (74); a snift pipe (78) connected to the filling nozzle; and an aseptic chamber (13) enclosing the filling nozzle (72), at least part of the carbonated beverage supplying pipe (73), and at least part of the counter pressure pipe (74). The carbonated beverage supplying pipe (73) and the counter pressure pipe (74) are attached to the aseptic chamber (13) by a rotary joint (77). A discharging valve (79) is provided in the snift pipe (78) inside the aseptic chamber (13), and gas from the snift pipe (78) is discharged into the aseptic chamber.

A filling method includes sealing a container against a filling element of a filling system, after the container has been sealed against the filling element and before beginning a filling phase, connecting the container to an annular vacuum duct, while the container is connected to the vacuum duct, carrying out an evacuation-and-flushing step in which the container is evacuated and flushed with flushing gas that comprises steam from an annular steam duct that carries pressurized steam, connecting the container to an annular pre-tensioning duct, pre-loading the container with inert gas from the pre-tensioning duct, filling the container with the liquid, and relieving pressure into the vacuum duct.

A filling method includes executing a pre-stressing phase, during which, at plural time intervals, gas is drawn from a gas space that lies above the filling material in a tank. The gas pre-stresses a container up to a second pressure that is below the pressure in the gas space. During a filling phase, a liquid valve opens to allow the filling material in the tank to enter into the container. This valve is above the level of the filling material, thus preventing gravity from driving the flow.
