  • Patent number: 5758789
    Abstract: A bottle for carbonated beverages is disclosed. The bottle almost completely prevents the dissolved carbonic dioxide from vaporizing and vanishing into carbonic acid gas when drinking the carbonated beverage sparingly, thus maintaining the cool and fresh taste of the carbonated beverage for a lengthy period of time. A bellows is formed on the bottle body and may be compressed by at least two strip fasteners, thus reducing the volume of the bottle. In order to couple the fasteners to the bottle, the bottle has at least two lock slits with respective elastic pawls and at least two passing slits with respective stop depressions. The lock slits may be formed on the neck flange of the bottle, while the passing slits may be formed on the bottle stand. Alternatively, the positions of the lock slits and the passing slits may be changed with each other.
