A bottling machine performs one or more of the processes required to fill a bottle and prepare the bottle and its contents for commercial sale. Some of the more common processes bottling machines perform are filling bottles, capping bottles, and labeling bottles.

These normally have a pneumatically powered pump mechanism, set to fill containers with the required volume of liquid, fed from either a floor-standing container or a machine-mounted hopper. Containers are positioned below the filling nozzles and a foot pedal switch to start the filling process.
