Abstract

A filling apparatus 1 is made up of a gas passage 14 connected to a storage tank 31 via a connection passage 14a, a first gas valve 35 that opens and closes the gas passage, a pressure gas passage 41 connected to a pressure gas supply source, a pressure gas valve 42 that opens and closes the pressure gas passage, an exhaust passage 43 that allows an interior of a container 4 to communicate with the exterior thereof, and an exhaust valve 44 that opens and closes the exhaust passage. With this filling apparatus, before a pressurized filling operation, both the gas passage and the pressure gas passage are opened to pressurize the interior of the container with a carbonated gas supplied through both passages. Further, also before a unpressurized filling operation, both the gas passage and the pressure gas passage are opened to perform a flushing operation in which droplets are discharged from the gas passage with air exhausted from the container into the storage tank via the gas passage. Then, after the filling operation, both the gas passage and the exhaust passage are opened to discharge a certain amount of filling liquid remaining in the gas passage, into the container.
