【Abstracts】 The utility model discloses a bottle with a pollution-proof sealed structure of a beverage bottle. The utility model comprises a bottle body with a male thread mouth and a bottle cap with a female thread structure; a cylindrical surface and a flange matching sealing structure are formed between the lower part of the male thread mouth and the bottom of the female thread structure of the inner wall of the bottle cap. Through the adoption of the above structure, the utility model can seal the threaded part of the beverage bottle through the cooperation of the flange and the cylindrical surface, so as to prevent it from being polluted, and is suitable for filling various beverages. Moreover, the additional structural weight of the caps and bottles is minimal; at the same time, the structure of the cap molds (injection molding and compression molding) does not become complicated, and the production of the preforms of the bottles does not complicate the blow molding process. The process is the same as the current production of bottle caps and bottles to reduce costs. When the inside bottom of the bottle cap of the utility model adopts the form of a sealing gasket, the packaging bottle can be expanded to be used for filling beverages with positive pressure in carbonated beverages and other bottles.
