Description

Technical Field

[0001] This utility model relates to the field of anti-counterfeiting packaging technology, specifically to an RFID-based anti-transfer device, bottle cap, and container. Background Technology

[0002] Traditional barcode, QR code, and laser anti-counterfeiting technologies have relatively simple anti-counterfeiting logic and lack secondary feedback, making them easy to damage and counterfeit. Customers cannot reliably verify the bottles they buy in real time. RFID (Radio Frequency Identification), commonly known as "electronic tags," is a non-contact automatic identification technology that automatically identifies target objects and obtains relevant data through radio frequency signals. It is currently widely used in the field of anti-counterfeiting packaging for goods.

[0003] Patent document CN112906845A discloses a method for using RFID caps with anti-counterfeiting and tamper detection functions. The RFID tag binds the chip and antenna coil together. The coil is divided into two parts: the main coil is connected to the chip's radio frequency pin to achieve energy acquisition in the form of electromagnetic coupling, and the secondary coil is connected to the chip's tamper detection pin. If the product is opened and the secondary coil breaks, a second scan will identify the opened state and transmit the opened state to the NFC master control device according to the relevant protocol.

[0004] However, the electronic tags in the aforementioned patent documents are passive electronic tags. Unless actively scanned and read, the tag cannot be activated and can only detect and record the secondary coil's status after being read and activated. Therefore, there is a risk that damage to the secondary coil cannot be detected and repaired. Utility Model Content

Detailed Implementation

[0020] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0021] Example 1 like Figure 1 As shown, the present invention provides an RFID-based anti-transfer device comprising: an RFID main control component 1, a power supply unit 2, and a trigger structure 303. The power supply unit 2 is electrically connected to the RFID main control component 1 and is used to supply power to the RFID main control component 1. Both are mounted on a second component. The trigger structure 303 is mounted on or integrally formed with the first component. (See reference...) Figure 4 As shown, the trigger structure 303 can be a protrusion structure. Through the relative movement between the first component and the second component, the trigger structure 303 comes into contact with the RFID master control component 1, thereby triggering the RFID master control component 1.

[0022] The RFID main control component 1 includes a circuit board 100 and a microcontroller 101 and a trigger unit 104 connected to the circuit board 100. The microcontroller 101 is electrically connected to the RFID tag 102 and the trigger unit 104 via the circuit board 100. Specifically, the microcontroller 101 and the RFID tag 102 can be connected via the I2C protocol, which is not a limitation of this invention. When the first component and the second component move relative to each other, the trigger structure 303 can contact the trigger unit 104 on the movement path, thereby activating the microcontroller 101 by receiving a signal from the trigger unit 104. The microcontroller then sends a corresponding signal to the RFID tag 102, at which point the RFID tag 102 knows that the item it is holding has been opened. The trigger unit 104 can be a toggle switch, a dome switch, or a pressure sensor. Contact with the trigger structure 303 generates a signal distinct from the non-contact state. The RFID tag 102 is used to establish near-field communication with the terminal device when scanned, and can also trigger the activation of the microcontroller 101 when scanned.

[0023] In addition, the RFID main control component 1 also includes an Internet of Things (NB-IoT) module 103 and a communication antenna 105. The NB-IoT module 103 is electrically connected to the microcontroller, and the communication antenna 105 is electrically connected to the NB-IoT module 103, for example, via a pin connection. The NB-IoT module 103 includes an NB-IoT wireless communication module and a SIM card (such as a patch SIM card). The SIM card is connected to the NB-IoT wireless communication module, and the NB-IoT wireless communication module is electrically connected to the microcontroller 101. When the microcontroller 101 is woken up, the NB-IoT module 103 can connect to the network through the communication antenna 105 and establish communication with the backend server, thereby enabling the backend server to know the current status and location information of the RFID-based anti-transfer device.

[0024] With the above structure, as long as the product containing the RFID-based anti-transfer device is opened, that is, relative movement occurs between the first and second components of the product, the triggering structure 303 can promptly trigger and activate the microcontroller 101. Thus, the RFID tag 102 can promptly receive the signal sent by the microcontroller 101 and execute its built-in anti-counterfeiting function, such as writing the opening information into its own memory.

[0025] Figure 2 The illustration shows an RFID-based anti-transfer bottle cap, representing a specific application scenario of the aforementioned RFID-based anti-transfer device. It includes a bottle cap body 3 and an RFID-based anti-transfer device. The bottle cap body 3 includes an outer shell 301 and an inner shell 304, serving as the first and second components, respectively. The outer shell 301 is fitted over the inner shell 304, forming a receiving space between them. The RFID main control component 1 and the power supply unit 2 are located within this receiving space.

[0026] like Figure 3 As shown, a trigger structure 303 is connected to the side of the inner wall of the outer shell 301. The trigger structure 303 is a protrusion. Multiple reinforcing ribs 302 are connected to the top of the inner wall of the outer shell 301 to increase the structural strength of the outer shell 301.

[0027] like Figure 4 As shown, in this embodiment, the top surface of the inner housing 304 is recessed inward to form a cavity, and the circuit board 100 is located inside the cavity. The outer wall of the inner housing 304 includes an RFID tag fixing groove 307, in which the RFID tag 102 is fixed. The outer wall of the inner housing 304 also includes a communication antenna fixing groove 308, in which the communication antenna 105 is fixed. In this way, the gap between the outer housing 301 and the inner housing 304 can be effectively reduced, making the bottle cap structure more compact. The effect after the inner housing 304 is assembled is as follows: Figure 5As shown, the RFID tag fixing slot 307 and the communication antenna fixing slot 308 have no overlap in the vertical direction. The advantage of this is that it can avoid mutual interference between the antennas in the two slots.

[0028] like Figure 6 As shown, when the outer shell 301 and inner shell 304 are assembled together, the inner shell 304 is confined within the outer shell 301 by a limiting structure and is difficult to detach, while the two are movably connected. At this time, the triggering structure 303 on the outer shell 301 has not yet come into contact with the triggering unit 104. Figure 7 As shown, when it is necessary to open the bottle cap, the outer shell 301 is rotated to move the trigger structure 303 to the position of the trigger unit 104 to form contact, thereby activating the microcontroller. At this time, the outer shell 301 abuts against the inner shell 304 through the trigger structure 303, so that the inner shell 304 limits the trigger structure 303, thereby allowing the outer shell 301 to drive the inner shell 304 to rotate, causing the bottle cap to detach from the bottle.

[0029] To ensure a more secure fixation of the RFID main control component 1, multiple clips 305 are connected to the inner wall of the recess to secure the circuit board 100 and prevent it from detaching from the recess. A stop structure 306 is connected to the inner wall of the recess, and the trigger unit 104 abuts against the stop structure 306. This stop structure supports the trigger unit 104 when the trigger structure 303 contacts it. It also supports the trigger unit 104 when the outer shell 301 and inner shell 304 rotate relative to each other, preventing it from rotating and failing to make contact with the trigger structure 303. A limiting protrusion is also connected to the inner wall of the recess. A corresponding limiting recess is provided on the circuit board 100, and the limiting protrusion is located within the limiting recess to circumferentially limit the circuit board 100, preventing it from deflecting within the recess.

[0030] Example 2 The RFID-based anti-transfer device of this invention can also be applied to other types of containers, such as packaging boxes. The trigger structure 303 can be set inside the box lid, and the RFID main control component 1 and power supply unit 2 can be set inside the box body, so that the microcontroller 101 can be triggered and activated in time when the box lid is separated from the box body.
