Definitions
- the present invention relates to a glass container having a film excellent in scratch resistance and alkali resistance and capable of preventing the glass container from being damaged, a method for manufacturing the glass container, and a manufacturing apparatus.
- the glass surface is scratched to impair the appearance of the glass, and the glass containers are easily chipped or broken due to the scratches.
- many glass containers for business use are often carried at the same time. For this reason, the glass containers collide with each other, causing scratches on the glass containers, and the glass containers are further damaged by repeated use. Often leads to chipping or breakage.
- the scratch may be a starting point for damage, leading to the damage of the glass container.

- chemical strengthening is a secondary process performed after a molded and slowly cooled product, the treatment requires a long time and costs.
- the compressive stress layer on the surface of the glass product formed by chemical strengthening is thin, so that the expected hardness and scratch strength cannot be obtained, and sufficient scratch resistance cannot be obtained.
- a technique for improving the scratch resistance effect by forming a tin oxide or titanium oxide film on the glass surface of a glass bottle is already known.
- an oxide film such as tin oxide or titanium oxide having a thickness of about 12 nm to 15 nm is formed on the surface of the glass immediately after the plate making and before slow cooling.
- a polyethylene-based resin film is further formed on the film after slow cooling to impart scratch resistance.
- the material treated in this way has insufficient alkali resistance, and in particular, the polyethylene resin component is immediately peeled off with an alkaline cleaning solution. It itself is easy to peel off, and the iris phenomenon and the whitening phenomenon occur.
- Patent Document 1 Japanese Patent Laid-Open No. 3-131547.
- the glass bottles prepared by this method have improved alkali resistance, when they are repeatedly washed using a dishwasher, the alkali resistance is not yet sufficient and the scratch resistance is not sufficient. Further, the glass bottle produced by this method is not suitable for a glass container in which aesthetics are important because an iris is likely to be formed when the film is thick.
