Patent ID: 8851387

Claim:
An anti-counterfeiting bottle, comprising: a metal cap; a bottle body; a RFID (Radio Frequency identification) tag, comprising: a grounded surface attached to the metal cap; a monopole antenna which is attached to the botte body without substantially contacting the metal cap and is electrically connected to the grounded surface; and a RFID chip which is attached to the bottle body and is electrically connected to the monopole antenna and the grounded surface respectively, wherein the RFID chip, the monopole antenna and the grounded surface form a loop structure; and a perforation line formed at a joint of the monopole antenna and the grounded surface, wherein when the metal cap is turned, the RFID tag is broken along the perforation line to separate the grounded surface and the monopole antenna, thereby destroying the loop structure, such that the RFID tag cannot be read anymore, thus achieving anti-counterfeiting function.
