A filling machine for the hot filling of containers includes a line for feeding the containers to at least one supporting plate and a line for unloading the filled container from the supporting plate. Above the supporting plate there is a filling head associated with a respective valve assembly to convey the liquid from a containment tank into the container to be filled.

The valve assembly is associated with an internally hollow feeder conduit which accommodates a suction conduit with at least one suction inlet configured to determine the liquid level inside the container.

The filling head includes a sealing element having a first sealing body configured to engage hermetically against the upper edge of the container and is associated with a vent adapted to pass between a position for sealing the chamber for passing liquid from the supply feeder conduit toward the container and a position for venting.

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 pressure filling method for pressure filling a container that has been sealed against a filling element includes connecting a container's interior to a vacuum, evacuating its contents, and flushing it with gas, at least some of which has been recovered during container processing and that has already been used during container processing.

The present disclosure is directed to a vent tube apparatus, system and methods incorporating a ball cage with a modified pill device design comprising a traceable material such as a Radio Frequency Identification (RFID) tag for use in conjunction with a filling machine during container filling operations for a quicker and more accurate detection of the location of the pill device to the extent it becomes detached from the ball cage during filling operations, and to increase the safety of the filling operation and reduce costs and time when a malfunction occurs.
