Description

Technical Field

[0001] This application belongs to the field of bottle cap anti-counterfeiting technology, specifically relating to an NFC tag with disconnection detection function and a smart bottle cap composed of the tag and the tag. Background Technology

[0002] Ordinary liquor bottle caps only serve a sealing and decorative purpose. Printing QR codes on the surface or inside the cap cannot effectively serve as an information-based anti-counterfeiting and traceability tool or facilitate interactive marketing. Utility Model Content

[0003] The technical problem to be solved by this application is to overcome the shortcomings of the prior art and provide an NFC tag with disconnection detection function and a smart bottle cap composed of the tag and the tag. In addition to sealing and decoration functions, the smart bottle cap of this application also has NFC anti-counterfeiting and traceability functions, disconnection detection functions, and interactive marketing code activation functions after opening. It can display the entire process information of wine production in real time, and intelligently feedback the opening status of the bottle cap through the detection line status, thereby establishing a consumer interaction channel and enhancing brand loyalty.

[0004] The technical solution adopted by this application to solve its existing problems is:

[0005] An NFC tag with disconnection detection function includes a face layer, an inlay layer, and a backing paper layer, wherein the inlay layer is sandwiched between the face layer and the backing paper layer.

[0006] The inlay layer includes interconnected NFC coils and NFC disconnection detection lines, with the NFC disconnection detection lines extending to the outside of the backing paper layer.

[0007] Preferably, the backing paper layer is made of a transparent material. An intermediate layer is provided between the backing paper layer and the inlay layer, and variable graphic information is provided on the intermediate layer.

[0008] Preferably, the backing paper layer uses double-sided adhesive tape with transparent PET as the release film.

[0009] A smart bottle cap, based on the aforementioned NFC tag with disconnection detection function, includes an inner cap and an outer cap fitted over the inner cap. The inner cap is made of a transparent material, and the backing paper layer is fixedly connected to the inner wall of the top of the inner cap. The NFC disconnection detection line is bent and positioned between the inner cap and the outer cap.

[0010] Preferably, the NFC disconnection detection line is coated with adhesive and is flatly attached to the outer wall of the inner cover sidewall.

[0011] Preferably, the inner wall of the outer cover sidewall is provided with reverse teeth at the position corresponding to the NFC disconnection detection line.

[0012] Compared with the prior art, the beneficial effects of this application are as follows:

[0013] (1) Adopting a partially fragile breakage detection line design: The built-in label of the smart bottle cap is divided into a main structure NFC coil part and a secondary structure breakage detection line part. The main structure part of the label is completely bonded to the inner cap of the smart bottle cap through an adhesive layer and is flatly attached to the top of the transparent inner cap. The variable information layer of the main label can be scanned through the transparent bottle cap for interactive marketing. The secondary structure part of the label is bent and completely bonded to the side wall of the inner cap of the smart bottle cap through an adhesive layer. This part is not covered by the PET of the middle layer and adopts an antenna structure with a release fragile process. When the bottle cap is opened, the outer cap is rotated and the toothed structure of the outer cap can easily break the breakage detection line part, which plays the role of breakage detection.

[0014] (2) Image and text comparison design: The variable information layer adopts a variable image and text design and does not use QR codes. Generally, QR codes are easy to copy, and when scanning through the inner cap, the depth of the inner cap makes it impossible to accurately recognize the QR code, resulting in recognition failure. The variable image and text method directly compares the images and text stored in the database by taking pictures with a camera, which can quickly query and compare for marketing interaction.

[0015] (3) NFC technology is adopted: Compared with barcode technology, NFC technology has the characteristics of unique chip code, non-visual recognition, multi-target recognition, and fast recognition. The management method based on NFC technology eliminates the possibility of batch copying of QR codes, improves the anti-counterfeiting registration of products, and allows for querying single-item-level traceability information through NFC.

Detailed Implementation

[0023] The attached figure shows a preferred embodiment of an NFC tag with disconnection detection function and a smart bottle cap, in particular. The present application will be further described in detail below with reference to the attached figure.

[0024] Depend on Figures 1 to 5 As shown, an NFC tag with disconnection detection function includes a face layer 1, an inlay layer 3, and a backing paper layer 8, with the inlay layer 3 sandwiched between the face layer 1 and the backing paper layer 8.

[0025] The surface layer 1 is made of 25μm to 50μm white PET self-adhesive material, with a first adhesive layer 2, which is bonded to the inlay layer 3.

[0026] The inlay layer 3 includes an interconnected chip body, an NFC coil 301, and an NFC disconnection detection line 302. The inlay layer 3 uses a locally fragile process to design the antenna. It uses 38μm PET as the substrate. The NFC coil 301 is designed on the front side of the PET substrate, and the NFC disconnection detection line 302 is designed on the back side as a locally pre-coated release layer. The line shape of the disconnection detection line is completed by aluminum etching process.

[0027] NFC coil 301 is a high-frequency coil with aluminum etching process. It is connected to the IN1 and IN2 pins of the chip to realize normal NFC reading and display the anti-counterfeiting and traceability information of the product. NFC disconnection detection line 302 is a fragile single coil with aluminum etching process. It is connected to the GND and DP pins of the chip to realize NFC disconnection detection and display information when the bottle cap has been opened.

[0028] The inlay layer 3 constitutes the NFC chip. Regardless of whether it is a high-frequency or ultra-high-frequency electronic tag, the inlay is composed of an antenna part and a chip. It is a semi-finished product of electronic tags. It usually needs to go through surface layer design and printing of logo, and use professional equipment for composite packaging to make a finished electronic tag.

[0029] The chip's GND and DP pins are shorted together by a wire, which can be either open or closed. When the reader sends a specific command to the chip, the chip returns the current pin connection status to the reader, displaying the current wire state. The chip can still ensure normal tag reading by using the original IN1 and IN2 pins.

[0030] The surface of the NFC tag is assigned a unique code through a digital device, and each tag has a unique code or graphic. The surface unique code is then linked with the chip UID, NFC URI and other information through an RFID information collection device. Finally, the NFC tag is used to display the product's single-item level anti-counterfeiting traceability and interactive marketing applications.

[0031] The base paper layer 8 is made of a transparent material. An intermediate layer 5 is provided between the base paper layer 8 and the inlay layer 3. An information layer 6 with variable graphic information is provided on the intermediate layer 5. The intermediate layer 5 uses 25μm–50μm white PET self-adhesive material and has a second adhesive layer 4, which adheres to the inlay layer 3. The variable graphic information uses a database random code design to select different random combinations of graphics and text, changing colors and graphic angles to ensure the uniqueness of the graphics and text on each label.

[0032] When positioning the composite, the width of the intermediate layer 5 is 3mm to 4mm narrower than that of the inlay layer 3, exposing part of the NFC disconnection detection line 302.

[0033] The base paper layer 8 uses double-sided adhesive tape with 50μm transparent PET as the release film. The side facing the middle layer 5 is the third adhesive layer 7, which is bonded to the information layer 6.

[0034] The semi-finished material after positioning and lamination is laminated with the base paper layer 8. The variable information layer can collect information through the transparent PET release film and associate it with NFC data.

[0035] A smart bottle cap, based on the aforementioned NFC tag with disconnection detection function, includes an inner cap and an outer cap fitted over the inner cap.

[0036] During the bottle cap assembly process, the inner cap of the smart bottle cap is transparent, and the NFC tag information layer 6 has adhesive on one side, which is pre-attached to the top cap 3 of the inner cap; the NFC tag disconnection detection line 3-2 has adhesive on one side, which is bent and flatly attached to the side wall 4 of the inner cap.

[0037] The inner cover is made of a transparent material, and the bottom paper layer 8 is fixedly connected to the inner wall of the top 11 of the inner cover. Information on the information layer 6 can be scanned by a mobile phone through the inner cover. The NFC disconnection detection line 302 is bent and positioned between the inner and outer covers. Furthermore, the NFC disconnection detection line 302 is coated with adhesive and is flatly attached to the outer wall of the inner cover sidewall 12.

[0038] The inner and outer covers are assembled together via a snap-fit ​​mechanism, allowing them to rotate. For example, the inner cover has an L-shaped groove on its outer side wall 12, with the upper opening of the groove located on the top surface of the inner cover top 11. The outer cover has a protruding protrusion on its inner side wall 10. When installing the inner and outer covers, the protrusion enters through the opening of the L-shaped groove on the top surface of the inner cover top 11, and after being inserted to the bottom, the outer cover is rotated to snap it into place with the inner cover.

[0039] Alternatively, the inner cap top 11 has an arc-shaped T-groove, with a large insertion port at one end. The outer cap top 9 has a T-shaped block inside. After the T-shaped block is inserted through the large insertion port, it rotates into the T-groove, causing the outer cap to engage with the inner cap. The inner wall of the outer cap sidewall 10 has countersunk teeth at the position corresponding to the NFC disconnection detection line 302. Rotating the outer cap will cause the countersunk teeth to break the fragile part of the NFC disconnection detection line 302 attached to the inner cap sidewall. When the NFC mobile phone reads the NFC coil 301 inside the cap, the displayed data information is that the tag has been damaged and the bottle has been opened. After opening the bottle cap, the information on the transparent inner cap can be scanned by a mobile phone for interactive marketing business management.

[0040] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
