ABSTRACT:
The present invention relates to a glass bottle coated with a multi-layer protective film comprising high polymer substances, and a method for producing such a coated glass bottle. More particularly, the invention is concerned with a glass bottle designed for containing carbonated beverages such as soft drinks or beer, wherein the beverages must be maintained under pressurized conditions, said bottle being coated on its outer wall by spraying or otherwise applying a plurality of protective films. Still more particularly, the present invention is directed to a "return-type" glass bottle for carbonated beverages such as soft drinks and beer, wherein the glass bottles are designed for repeated use, each cycle of which requires washing and sterilizing steps prior to filling.
The present invention also provides for a method for coating the glass bottle with protective films which will prevent or retard the scattering of glass fragments when the bottle is broken due to internal pressure exerted by the pressurized gas within the bottle, or due to external forces such as impact. The coatings of the present invention are adapted to prevent the scattering of glass fragments around the surrounding area in the event a coated bottle breaks or explodes.
