Definitions
- the present invention relates to a synthetic resin container represented by a polyethylene terephthalate bottle, a so-called PET bottle, which prevents gas permeation into the container, in particular, oxygen gas and carbon dioxide gas. Therefore, the quality of the contents is stably maintained.
- blow containers made of synthetic resin have been frequently used as containers for soft drinks, alcohol, oil, soy sauce, etc., because disposal, transportation, recycling, and the like are easy to handle! RU
- this type of container cannot avoid the permeation of oxygen gas and carbon dioxide gas, and thus has a short shelf-live that can maintain the quality of the contents.
- Japanese Patent Application Laid-Open No. 2000-109076 proposes a container in which a gas-nolia high coating (SiO 2) is coated on the inner surface of a bottle by vapor deposition or sputtering.
- other containers have been proposed, including a compound film containing silicon, carbon and oxygen and located on the surface of the container body, and a two-layer film of a silicon oxide compound located on the surface of the compound film.
- Such containers can improve oxygen nobility (PET bottle oxygen nobility) several times more than uncoated containers, and can stably maintain the quality of the contents.
- further improvement in gas nori- lation has been required to achieve long-term stability. Disclosure of the invention
- An object of the present invention is to propose a new synthetic resin container having higher gas barrier properties.
- the present invention relates to a synthetic resin container having a coating having high gas barrier properties on at least one of the inner surface and the outer surface of the container body,
- At least the coating is located on the surface of the container body and includes an organic silicon compound layer containing nitrogen, silicon, carbon, hydrogen, and oxygen; and an organic silicon compound layer located on the surface of the organic silicon compound layer.
- a synthetic resin container having a high barrier property comprising a silicon oxide compound layer containing a silicon compound as a main component.
- an organic silicon compound layer containing nitrogen is located on the surface (inner and outer surfaces) of the container body as a first layer of a coating film, and a second layer is formed on the surface of the organic silicon compound layer.
- the organic silicon compound layer and the Z or silicon oxide compound layer are preferably formed as vapor-deposited films, and those having a refractive index in the range of 1.3 to 1.6 are particularly desirable. Good.
- FIG. 1 is a sectional view of a main part of a synthetic resin container according to the present invention.
- Fig. 1 shows, in cross section, the main parts of a PET bottle formed by biaxial stretch blow molding
- reference numeral 1 denotes a wall constituting the container body
- 2 denotes a wall provided on the wall 1 for use in or inside the container. It is a coating with high barrier properties to prevent gas (particularly oxygen gas, carbon dioxide gas, etc.) from permeating outside the container.
- the coating 2 contains nitrogen, silicon, carbon, hydrogen and oxygen, and has an organic silicon compound layer 2a located on the outer surface of the container body 1 and a silicon oxide layer located on the surface of the organic silicon compound layer 2a.
- the silicon nitride compound layer 2b containing a compound as a main component is formed.
- the organic silicon compound layer 2a is formed by adding a nitrogen gas instead of an inert gas (a rare gas element such as Ar) when forming the layer.
- an inert gas a rare gas element such as Ar
- the conventional organic silicon compound layer containing silicon, carbon, and oxygen has almost no gas-no-reactivity itself, and the organic silicon compound layer 2a in the present invention also has the above-mentioned conventional silicon compound layer. This is similar to the organic silicon compound layer, and there is no significant difference in this point.
- a compound layer having a gas barrier property containing silicon oxide as a main component
- the present invention merely shows the gas nolia property, and in the present invention, no significant improvement in the gas nolia property due to the synergistic effect of the two kinds of films obtained can be expected.
- a coating was formed on the surface of the PET bottle by a plasma CVD method using a high-frequency pulse, and the oxygen noria (oxygen permeability and moisture permeability) of the PET bottle was investigated.
- the results are shown in Tables 1 and 2, respectively.
- the pulse discharge conditions in plasma CVD are On: 0.1 sec, Off: 0.1 sec.
- Table 1 shows the results when Ar gas was used to provide the organic silicon compound layer
- Table 2 shows the results when nitrogen gas was used to provide the organic silicon compound layer.
- DEPO is the discharge time (for example, 8 means pulse discharge 8 sec)
- HMDSO is hexamethyldisiloxane
- sccm is 0 ° C, 1 ° C. It means the amount of gas (cc) flowing per minute under atmospheric pressure.
- composition ratio of raw material gas is a ratio of a state in which gases such as HMDSO, oxygen, nitrogen, and argon are mixed.
- gases such as HMDSO, oxygen, nitrogen, and argon are mixed.
- Relative humidity, “BIFJ is the Barrier Improvement Factor compared to the uncoated product.
