Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a returnable glass bottle that does not cause any change in the appearance of the content therein after being coated with one layer of colorless transparent film, superior in alkaline cleaning resistance and damage resistance, withstanding repeated use, with the coating film being of minimal thickness and formed only on the necessary portion eliminating fear of coloring even when reused as glass cullet, and effectively reusable as is capable of being minutely crushed. SOLUTION: A glass bottle body 1 has its contact point on the outer surface treated with primer and further has a resin coating film 2 formed in a belt form made of a mixture of urethane resin having alkali resistance and styrene- butadiene rubber. |
