An apparatus for filling with a propellant material aerosol containers of the type which have an opening in the container bottom with a valve forming member enabling propellant material to be introduced through said opening, which apparatus comprises a metering valve assembly incorporated in a container filling machine which has a series of filling stations each with a means operable for sealing the container closure cap and its associated valve assembly to the mouth of the container so as to close the same, and a combination container support and stripper platform at each station which is resiliently mounted above the metering valve so that downward pressure on the container resulting upon operation of the cap sealing means lowers the platform and effects a connection between the bottom fill valve or the bottom of the container and the metering valve so as to permit entry of the propellant through the bottom opening while the closure cap is being sealed on the container mouth.
