Description

Technical Field

[0001] The utility model relates to the technical field of bottle caps, in particular to a double-color anti-counterfeiting bottle cap. Background Art

[0002] At present, unscrupulous merchants often recycle empty beverage bottles, wine bottles and other bottles containing liquids, fill the bottles with inferior, non-genuine liquids, and reseal them for sale. For this reason, many merchants will add anti-counterfeiting structures to the bottles during production to prevent imitation by unscrupulous merchants. In the prior art, merchants usually add a disposable anti-counterfeiting ring to the bottom of the bottle cap to prevent beverage bottles from being counterfeited. However, in the process of putting them on the market, it will be found that: 1. The identification degree of the disposable anti-counterfeiting ring is too low, and many times users will not pay attention to the anti-counterfeiting effect of the anti-counterfeiting ring itself when using it; 2. The bottle caps of existing beverage bottles are usually mostly monochrome designs, and it is not technically difficult to imitate the same bottle caps. Utility Model Content
