Abstract
[Object] To provide a resin container having a dense and. thin coating with good gas barrier properties and a resin-container coating apparatus. [Solution] A metal oxide film 102 is formed on at least one of inner and outer surfaces of a resin container 101. The metal oxide film 102 includes a stack of layers of a metal forming the metal oxide film that are deposited on an atomic level and has a thickness of 5 to 100 nm.
Claims6
A resin container having a metal oxide film formed on at least one of inner and outer surfaces thereof,
- wherein the metal oxide film comprises a stack of layers of a metal forming the metal oxide film that are deposited on as atomic level and has a thickness of 5 to 100 nm.
A resin-container coating apparatus comprising a reaction vessel in which a resin container is supported;
- a mechanism that maintains the temperature in the reaction vessel at 0° C. to 150° C.;
- supply means for supplying a gasified organometallic to the reaction vessel;
- plasma-gas supply means for introducing a gas comprising water vapor or oxygen through a tube that leads to the reaction vessel and that comprises a dielectric including glass, the plasma-gas supply means comprising a mechanism that creates a radio-frequency magnetic field in and around the tube to generate plasma in the tube;
- and control means for repeating a step of diffusing the gasified organometallic supplied from the supply means to allow the organometallic to adsorb onto the resin container and a step of oxidizing the organometallic adsorbed on the resin container with the gas, comprising water vapor or oxygen and excited with the plasma, supplied from the plasma-gas supply means.
