A barrier-film forming apparatus that forms a barrier film on an inner face of a container having a concave or convex portion as a processing target, including: a dielectric member having a cavity sized to enclose the container, an external electrode covering an outer circumference of the dielectric member, an exhaust unit installed on an end face of the external electrode on a side where a mouth of the container is located, with an insulating member interposed therebetween, and depressurizing inside of the container through an exhaust pipe, an internal electrode inserted from a side of the exhaust pipe and also serving as a gas blowout unit that blows out medium gas for generating a barrier film into the container, and an electric-field applying unit that applies an electric field for generating exhaust between the external electrode and a ground electrode.

Barrier-film forming apparatus, barrier-film forming method, and barrier-film coated container

An inner electrode for barrier film formation is an inner electrode for barrier film formation that is inserted inside a plastic container having an opening, supplies a medium gas to the inside of the plastic container, and supplies high frequency power to an outer electrode arranged outside the plastic container, thereby generating discharge plasma on the inner surface of the plastic container to form a barrier film on the inner surface of the plastic container, and that is provided with a gas supply pipe having a gas flow path to supply a medium gas and an insulating member screwed into an end portion of the gas supply pipe to be flush therewith and having a gas outlet communicated with the gas flow path.
