Abstract
Abstract The present invention relates to a high pressure resin-coated glass bottle containing a polyvinyl alcohol resin on the surface of the bottle and an alkali-resistant layer on the surface of the polyvinyl alcohol resin. The resin-coated bottles are especially adapted for bottling effervescent or carbonated beverages from a safety standpoint in that if they explode, the resin prevents the bottle fragments from scattering and injuring nearby persons.
