Description
Technical Field
The invention belongs to the technical field of RFID (radio frequency identification) tags, relates to an RFID functional bottle cap, and particularly relates to an RFID functional plastic bottle cap which forms a high-degree coupling between an RFID top antenna and a bottleneck metal foil, and forms a low-degree coupling between a near-field antenna loop and the bottleneck metal foil to form a large signal-enhanced antenna.
Background
The electronic tag is used as a data carrier and can play the roles of identification, article tracking and information acquisition. And an RFID system consisting of the electronic tag, the reader-writer, the antenna and the application software is directly connected with the corresponding management information system. Each item can be accurately tracked, including real-time data acquisition, secure data access channels, all product information available off-line, and the like.
The existing plastic containers for packaging foods, pharmaceuticals, cosmetics, cleaning products, nutriments and health care products are mostly identified by one-dimensional bar codes or two-dimensional bar codes, and a small number of the containers are stuck with RFID labels. Although the bar code or the two-dimensional code can be identified, the following defects exist: (1) the code is easy to decode, copy and forge; (2) the label can only read the code and can not continuously record data; (3) during identification, the bar codes are required to be aligned by a bar code scanner and read one by one, which wastes time and labor; (4) the bar code is marked or pasted after the product is finished and packaged, and the data history in the production is difficult to trace.
Although the defects of the bar code mode are partially improved by sticking the RFID label on the package or the bottle cap, the following problems are not solved: (1) the label is easy to be heated, taken down and repeatedly stuck on the counterfeit product; (2) the concealment of the label is not good; (3) the label is attached to the container after the product manufacturing process is completed and the product is packaged, and the data record tracing depth in the production process is insufficient.
As shown in fig. 1, although the RFID tag is injection-molded on the top of the inside of the bottle cap, although it is a great improvement, if a metal foil, mainly an aluminum foil, is used for sealing the bottle body, interference such as shielding and reflection of an RFID signal is formed due to the overlapping of the metal foil and the RFID antenna, so that the bottle body of the RFID bottle cap combined in this way cannot be read or written.
