Abstract: This invention is related to an anti-counterfeiting bottle cap that includes an outer cap made up of an upper outer cap and a lower outer cap connected by a breaking ring and an inner cap. The said inner cap at the end of which a protuberant identifying ring is set and the upper outer cap are fastened with each other. The breaking ring lies above the identifying ring which inserts in the sunk head on top of the lower outer cap. The breaking ring breaks revealing the identifying ring when the bottle is uncapped. With its radius bigger than that of the sunk head on top of the lower outer cap, the identifying ring can not be buried in the sunk head when the bottle is capped to be anti-counterfeiting. No breakage to the cap is made when the bottle is uncapped so that reseal of the remnants is not affected.
