Claim:
A storage container for containing a carbon dioxide, which is used for a method for molding a molded article by introducing a liquid carbon dioxide, in which a metal complex or a metal alkoxide is dissolved, to a melted resin in a plasticizing cylinder of an injection molding machine or the resin which is in a melted state or a softened state in a extrusion molding machine to impregnate the carbon dioxide into a resin, the storage container comprising: the carbon dioxide in a gas-liquid mixed state; the metal complex or the metal alkoxide, being dissolved in the carbon dioxide in the gas-liquid mixed state, which modifies a surface or a interior of the molded article; a container body which hermetically contains the carbon dioxide in the gas-liquid mixed state in which the metal complex or the metal alkoxide is dissolved not more than a saturation solubility; a siphon tube through which only liquid phase, in which the metal complex or the metal alkoxide is dissolved, is taken out from the carbon dioxide in the gas-liquid mixed state in the container body.
