Abstract
A propellant filling device that reliably fills a prescribed amount of propellant into an aerosol container without variations in amount while also preventing backflow to a supply unit side even when the pressure in the aerosol container is higher than a supply unit side pressure. The propellant filling device includes a valve opening member that continuously presses a valve to open a valve system. On the upper end side of the valve opening member, a flow conduit is provided. A valve member in the flow conduit allows a flow channel of the flow conduit to be closed. The valve system is kept in an open state. When the pressure in the aerosol container is higher than the supply unit side pressure, the propellant flows into the aerosol container with backflow of aerosol content being prevented.
