摘要

A filling device for use in a bottling machine, which device is provided with a sealing member for closing the opening of a bottle, a filling tube for supplying the bottle with a filling liquid and an exhaust tube for discharging the air from the bottle to the outside during the filling operation. When the opening of the bottle is closed by the sealing member, the filling liquid is fed into the bottle through the filling tube and the air in the bottle is simultaneously discharged outside. The filling device is provided with a valve mechanism which receives the pressure of the air remaining in the bottle as an indication pressure when the filling liquid in the bottle blocks the lower end of the exhaust tube. The valve mechanism closes the exhaust tube or the filling tube when the indication pressure exceeds a predetermined value.
