Description

Technical Field

[0001] This application relates to the field of container packaging technology, and in particular to an anti-counterfeiting bottle cap. Background Technology

[0002] Counterfeit alcoholic beverages exist in the current market. To protect consumers' rights, RFID electronic tags have emerged as a method for verifying the authenticity of alcoholic beverages. RFID tags can be placed on bottle caps, bottles, or inside packaging boxes. Merchants pre-write genuine product information into the RFID tags, and consumers can identify the brand and other information to verify the authenticity of the alcoholic beverage, thus avoiding the purchase of counterfeit products.

[0003] In related technologies, RFID tags are typically attached inside the bottle cap. The RFID tag cannot be removed without opening the cap, providing a certain level of security. Consumers can also obtain information from the RFID tag to determine the authenticity of the alcohol without opening the cap. However, this method of attaching the RFID tag inside the bottle cap does not damage the tag once the cap is opened. Therefore, it is possible for the RFID tag of genuine alcohol to be collected and placed in counterfeit alcohol, making it impossible for consumers to distinguish between genuine and counterfeit products and harming their rights. Therefore, it is necessary to design a bottle cap with anti-counterfeiting features that is non-reusable. Summary of the Invention

[0004] Therefore, it is necessary to provide an anti-counterfeiting bottle cap to address the problem of RFID electronic tags in the bottle caps being easily reused.

[0005] An anti-counterfeiting bottle cap, comprising:

[0006] RFID electronic tags;

[0007] The inner cover has a first protrusion on its outer side wall;

[0008] A liner is fitted around the outer periphery of the inner cover and rotatably connected to the inner cover. The liner includes an annular wall, a mounting plate, and a connecting plate. The mounting plate and the connecting plate are both connected to the annular wall. The inner sidewall of the connecting plate is provided with a second protrusion.

[0009] The mounting plate is fixedly connected to a portion of the RFID electronic tag, and the connecting plate is fixedly connected to another portion of the RFID electronic tag. When the inner cover and the liner rotate relative to each other, the first protrusion and the second protrusion abut against each other and drive the connecting plate away from the mounting plate, so that the connecting plate and the mounting plate tear the RFID electronic tag in opposite directions.

[0010] In some embodiments, the RFID electronic tag includes a main coil and a connecting wire, the connecting wire being integrated with the main coil to achieve electrical connection between the two, the main coil being fixedly connected to the mounting plate, and the connecting wire being fixedly connected to the connecting plate.

[0011] In some embodiments, the mounting plate and the connecting plate are spaced apart along the circumferential direction of the annular wall; the anti-counterfeiting bottle cap further includes a first connector, a second connector, and a third connector. The first connector is disposed between the main coil and the mounting plate, and the main coil is fixedly connected to the mounting plate via the first connector. The second connector is disposed between the connecting line and the connecting plate, and a portion of the connecting line is fixedly connected to the connecting plate via the second connector. The third connector is disposed between the first connector and the second connector, and the first connector and the second connector are connected via the third connector. Another portion of the connecting line is fixedly connected to the third connector. The third connector is capable of breaking, allowing the connecting plate to move away from the mounting plate.

[0012] In some embodiments, fracture grooves are provided at the opposite two edges of the third connector, and the fracture grooves extend to the opposite side of the third connector.

[0013] In some embodiments, the annular wall of the liner is formed with a receiving groove, and the connecting plate is disposed in the receiving groove. When the liner and the inner cover move relative to each other, the connecting plate moves along the length direction of the receiving groove.

[0014] In some embodiments, the liner further includes connecting ribs, through which the connecting plate is connected to the annular wall.

[0015] In some embodiments, the outer side wall of the inner cover is provided with a third protrusion, and the inner side wall of the liner is provided with a fourth protrusion corresponding to the third protrusion. The third protrusion and the fourth protrusion are spaced apart. When the inner cover and the liner rotate relative to each other by a certain distance, the third protrusion can abut against the fourth protrusion.

[0016] In some embodiments, the outer side wall of the inner cover is provided with a clearance groove, the third protrusion is correspondingly provided with the clearance groove, and the fourth protrusion is provided in the clearance groove.

[0017] In some embodiments, the outer wall of the annular wall is provided with a serrated structure, which is arranged along the circumferential direction of the annular wall.

[0018] In some embodiments, the anti-counterfeiting bottle cap further includes an outer cap, which is fitted around the outer periphery of the liner and fixedly connected to the liner.

[0019] The aforementioned anti-counterfeiting bottle cap includes an inner cap and a liner that are rotatably connected. The two caps can rotate relative to each other. At least one of the inner cap and the liner, or through other structures in conjunction with the inner cap and the liner, is positioned at the bottle opening to achieve a bottle seal. Both the mounting plate and the connecting plate are connected to the annular wall. An RFID electronic tag is used to realize the RFID electronic tag identification function. Part of the RFID electronic tag structure is fixed to the mounting plate, and another part of the RFID electronic tag structure is fixedly connected to the connecting plate. The first protrusion moves with the inner cap, and the second protrusion rotates with the liner. When the bottle cap needs to be opened, the inner cap and the liner move relative to each other, and the first and second protrusions approach each other until they abut. The inner cap and the liner continue to rotate relative to each other. The first protrusion applies a pushing force to the connecting plate through the second protrusion. When the pushing force reaches a certain value, the connecting plate moves away from the mounting plate under the influence of the first protrusion. Because part of the RFID electronic tag structure is pulled by the connecting plate, the part of the RFID electronic tag connected to the mounting plate breaks from the part connected to the connecting plate, thereby destroying the overall structure of the RFID electronic tag. After the RFID tag breaks, the inner cover and the liner rotate synchronously, or the inner cover and the liner are disassembled to open the liner and the inner cover. Through the above settings, the relative movement between the liner and the inner cover during the opening process tears the RFID tag, causing it to break and become damaged, thus destroying its identification function and rendering it irreparable. This effectively prevents reuse. Attached Figure Description

Therefore, this application is not limited to the specific embodiments disclosed below.

[0031] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0032] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0036] See Figures 1 to 4 , Figure 1 A schematic diagram of the anti-counterfeiting bottle cap according to one embodiment of this application is shown. Figure 2 This illustration shows a schematic diagram of the structure of the liner in an anti-counterfeiting bottle cap according to one embodiment of the present application. Figure 3 This illustration shows a structural diagram of the second protrusion in an embodiment of the anti-counterfeiting bottle cap. Figure 4A schematic diagram of the structure of the inner cap in an embodiment of this application is shown. An embodiment of this application provides an anti-counterfeiting bottle cap, which includes an RFID electronic tag 100, an inner cap 200, and a liner 300. The outer side wall of the inner cap 200 is provided with a first protrusion 210. The liner 300 is fitted around the outer periphery of the inner cap 200 and rotatably connected to the inner cap 200. The liner 300 includes an annular wall 310, a mounting plate 320, and a connecting plate 330. Both the mounting plate 320 and the connecting plate 330 are connected to the annular wall 310. The inner side wall of the connecting plate 330 is provided with a second protrusion 331. The mounting plate 320 is fixedly connected to a portion of the RFID electronic tag 100, and the connecting plate 330 is fixedly connected to another portion of the RFID electronic tag 100. When the inner cover 200 and the liner 300 rotate relative to each other, the first protrusion 210 and the second protrusion 331 abut against each other and drive the connecting plate 330 away from the mounting plate 320, so that the connecting plate 330 and the mounting plate 320 tear the RFID electronic tag 100 in opposite directions.

[0037] It should be noted that when using anti-counterfeiting bottle caps, manufacturers can write genuine product information into the RFID electronic tag 100. Consumers can then determine the authenticity of the product by reading the pre-written signals in the RFID electronic tag 100. For example... Figures 1 to 4 As shown, the liner 300 is fitted around the outer periphery of the inner cover 200 and the liner 300 is rotatable relative to the inner cover 200. The outer side wall of the inner cover 200 is provided with a first protrusion 210, and the inner side wall of the connecting plate 330 of the liner 300 is provided with a second protrusion 331. The first protrusion 210 and the second protrusion 331 are correspondingly arranged so that the first protrusion 210 and the second protrusion 331 can contact each other during the relative rotation of the liner 300 and the inner cover 200. Since part of the RFID electronic tag 100 is fixedly connected to the connecting plate 330 and another part of the RFID electronic tag 100 is fixedly connected to the mounting plate 320, it is easy to understand that when the first protrusion 210 and the second protrusion 331 abut against each other, the cover 300 and the inner cover 200 rotate relative to each other. The first protrusion 210 and the second protrusion 331 exert a pushing force on each other, thereby causing the connecting plate 330 to move away from the mounting plate 320 under the push of the first protrusion 210. As a result, the part of the RFID electronic tag 100 connected to the connecting plate 330 and the part connected to the mounting plate 320 are torn apart, the RFID electronic tag 100 is damaged, its identification function is disabled, and the RFID electronic tag 100 cannot be reused.

[0038] It should be noted that at least one of the inner cap 200 or the liner cap 300 is placed over the bottle opening to achieve a bottle seal. The bottle cap is opened by rotating the inner cap 200 or the liner cap 300. It should also be noted that the bottle opening can be sealed by the inner cap or the liner cap alone, or by a combination of the inner cap and the liner cap, or by the inner cap and the liner cap in conjunction with other structures. The above configurations are only some feasible embodiments, and no specific sealing method for the bottle opening is limited here.

[0039] like Figure 1 The anti-counterfeiting bottle cap shown is located at the bottle opening. To open the bottle opening, the anti-counterfeiting bottle cap needs to be rotated. Rotating the inner cap 200 or the liner 300 causes the inner cap 200 and the liner 300 to rotate relative to each other, bringing the first protrusion 210 and the second protrusion 331 closer together until they abut against each other. Continuing to rotate the inner cap 200 or the liner 300 causes the connecting plate 330 to move away from the mounting plate 320, thereby tearing the RFID electronic tag 100. Continuing to rotate the inner cap 200 or the liner 300 allows both the inner cap 200 and the liner 300 to rotate relative to the bottle body, thereby causing the anti-counterfeiting bottle cap located at the bottle opening to detach from the bottle opening, thus opening the bottle opening. In other embodiments, after tearing the RFID tag 100, continuing to rotate the inner cover 200 or the liner 300 can create an opening between the inner cover 200 and the liner 300. Liquid inside the bottle can then flow out through this opening, meaning the bottle opening can be opened without the liner 300 and the inner cover 200 needing to detach from the bottle opening. The above methods of opening the bottle opening are merely examples of feasible embodiments for ease of understanding, and no specific method of opening the bottle opening is limited here.

[0040] With the above settings, the RFID tag 100 can be broken when the cover is opened, thereby rendering the identification function invalid and irreparable, effectively preventing the RFID tag 100 from being reused for counterfeiting.

[0041] like Figures 6 to 9 As shown, further, in the initial state, i.e., the storage state, there is a certain gap between the first protrusion 210 and the second protrusion 331. The inner cover 200 or the liner 300 needs to be rotated a certain angle before the first protrusion 210 and the second protrusion 331 can abut against each other. This can prevent the RFID electronic tag 100 from breaking due to bumps or other situations during storage or transportation. For ease of understanding, if the first protrusion 210 and the second protrusion 331 abut against each other in the initial state, then a slight bump to the RFID electronic tag 100 during storage or transportation would cause the connecting plate 330 to move away from the mounting plate 320, resulting in the breakage of the RFID electronic tag 100. By setting the first protrusion 210 and the second protrusion 331 at a distance, non-human-caused damage to the RFID electronic tag 100 can be effectively avoided.

[0042] Taking the rotation of the inner cap 200 relative to the liner 300 as an example, after the connecting plate 330 moves away from the mounting plate 320, causing the RFID electronic tag 100 to break, the connecting plate 330 abuts against the annular wall 310 and pushes the annular wall 310 and the liner 300 to rotate. This causes the inner cap 200 and the liner 300 to rotate synchronously. It can be easily understood that the steps of rotating to open the cap include three stages. In the first stage, the inner cap 200 and the liner 300 rotate relative to each other, causing the first protrusion 210 to abut against the second protrusion 331. In the second stage, the connecting plate 330 moves away from the mounting plate 320 and moves a certain distance to ensure that the RFID electronic tag 100 breaks. In the third stage, the connecting plate 330 separates from the annular wall 310, and the protrusion on the inner cap 200 abuts against the protrusion on the liner 300. The abutment between the inner cap 200 and the liner 300 allows the liner 300 and the inner cap 200 to rotate synchronously to open the bottle cap. It should be noted that the protrusion on the inner cover 200 that abuts against the liner 300 can be the first protrusion 210 or other protrusions. The above-mentioned method of abutting between the liner 300 and the inner cover 200 is only one feasible embodiment and not the only feasible solution. It is only necessary to ensure that the inner cover 200 and the liner 300 can rotate synchronously after the RFID electronic tag 100 breaks.

[0043] like Figure 1 and Figure 5 As shown, in some embodiments, the RFID electronic tag 100 includes a main coil 110 and a connecting line 120. The connecting line 120 is integrated with the main coil 110 so that the two are electrically connected. The main coil 110 is fixedly connected to the mounting plate 320, and the connecting line 120 is fixedly connected to the connecting plate 330.

[0044] Most of the structure of the RFID electronic tag 100 constitutes the main coil 110, while a small portion forms the connecting line. In simple terms, the RFID electronic tag 100 is arranged around the coil to form the main coil 110. The RFID electronic tag 100, located at one edge of the coil, extends away from the main coil 110. After extending a certain length, the RFID electronic tag 100 bends and extends towards the main coil 110 until it connects with it. Thus, the RFID electronic tag 100 consists of two parts: the main coil 110 and the connecting line 120. The connecting line 120 extends from the main coil 110 on the mounting plate 320 to the connecting plate 330. The connecting line 120 is electrically connected to the main coil 110 to form a circuit, enabling the RFID electronic tag 100 to perform its identification function. When the connecting plate 330 moves away from the mounting plate 320, the connecting line 120 is torn and breaks, causing damage to the circuit. With the above settings, the RFID electronic tag 100 can be made to have easily tearable parts, so that the RFID electronic tag 100 can break at a specific location during the tearing process, thus avoiding the uncontrollable breakage location of the RFID electronic tag 100.

[0045] In some preferred embodiments, the number of turns of the connecting wire 120 is less than the number of turns of the main coil 110. It is easy to understand that the user only needs to apply a small force to tear the connecting wire 120. That is, the connecting wire 120 is easier to break than the main coil 110, making the breaking operation of the RFID electronic tag 100 easier and more convenient.

[0046] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the mounting plate 320 and the connecting plate 330 are spaced apart along the circumferential direction of the annular wall 310; the anti-counterfeiting bottle cap also includes a first connector 400, a second connector 410, and a third connector 420. The first connector 400 is disposed between the main coil 110 and the mounting plate 320, and the main coil 110 is fixedly connected to the mounting plate 320 through the first connector 400. The second connector 410 is disposed between the connecting line 120 and the connecting plate 330, and a portion of the structure of the connecting line 120 is fixedly connected to the connecting plate 330 through the second connector 410. The third connector 420 is disposed between the first connector 400 and the second connector 410, and the first connector 400 and the second connector 410 are connected through the third connector 420. Another portion of the structure of the connecting line 120 is fixedly connected to the third connector 420. The strength of the third connector 420 is less than the strength of the first connector 400 and the strength of the second connector 410.

[0047] Mounting plate 320 and connecting plate 330 are spaced apart. First connector 400, second connector 410, and third connector 420 are all plate-shaped structures. The main coil 110 is connected to the outer wall of mounting plate 320 via first connector 400. A portion of the connecting wire 120 is connected to the outer wall of connecting plate 330 via second connector 410, ensuring the main coil 110 and connecting wire 120 are on the same side of cover 300 for easy connection. Third connector 420 is located between connecting plate 330 and mounting plate 320. The portion of connecting wire 120 between connecting plate 330 and mounting plate 320 is fixed to third connector 420. Third connector 420 provides support for this portion of connecting wire 120, preventing it from being suspended and easily bent. The third connector 420 is designed with a fracture-prone structure, such as having a smaller cross-sectional area than the connecting plate 330 and the mounting plate 320, or being made of a fracture-prone material. This ensures that the strength of the third connector 420 is less than that of the first connector 400 and the second connector 410, guaranteeing that the fracture occurs at the third connector 420. This makes the fracture point controllable and ensures that the intended function can be performed normally. Through this design, the mounting plate 320 and the connecting plate 330 are indirectly connected via the third connector 420, which limits the fracture point to the third connector 420. This prevents the fracture point from being located at the mounting plate 320 or the connecting plate 330, which could damage the overall structure of the liner 300 and render the anti-counterfeiting cap unusable.

[0048] It should be noted that since the first connector 400, the second connector 410, and the third connector 420 are separate from the cover 300, the cover 300 can be manufactured using a specified mold, while the third connector 420 can have its cross-sectional area, thickness, and other parameters adjusted according to actual usage needs. In other words, the cover 300 and the connectors can be manufactured separately, reducing processing difficulty. The spaced arrangement of the connecting plate 330 and the mounting plate 320 further reduces processing difficulty. For ease of understanding, if the mounting plate 320 and the connecting plate 330 were directly connected, i.e., without connectors, it would be difficult to adjust the mold for the cover 300, and thus difficult to adjust the dimensions of the connection between the mounting plate 320 and the connecting plate 330, making the connection part more difficult to process.

[0049] like Figure 5 As shown, in some embodiments, fracture grooves 421 are provided on both opposite sides of the third connector 420, and the fracture grooves 421 extend to the opposite side of the third connector 430.

[0050] The third connector 420 has multiple fracture grooves 421 on both opposite sides. The multiple fracture grooves 421 on the same side of the third connector 420 are spaced apart, forming a pattern as follows: Figure 5 The structure shown above. This design makes the third connector 420 easier to break, thus facilitating its use.

[0051] like Figure 1 and Figure 2 As shown, in some embodiments, the annular wall 310 of the cover 300 is formed with a receiving groove 311, and the connecting plate 330 is disposed in the receiving groove 311. When the cover 300 and the inner cover 200 move relative to each other, the connecting plate 330 moves along the length direction of the receiving groove 311.

[0052] The connecting plate 330 is disposed within the receiving groove 311, which restricts the movement direction of the connecting plate 330. This configuration restricts the movement direction of the connecting plate 330, preventing it from shifting or falling during movement, thus facilitating the collection of the connecting plate 330 that has separated from the annular wall 310.

[0053] It should be noted here that, as Figures 6 to 9 As shown, after the connecting plate 330 moves a certain distance along the receiving groove 311, it will abut against the inner wall of the receiving groove 311, thereby driving the liner 300 and the inner cover 200 to rotate synchronously. The above solution is a feasible embodiment of the liner 300 driving the inner cover 200, which is only for the purpose of understanding the solution of this application and does not limit the specific solution of the liner 300 driving the inner cover 200.

[0054] like Figure 1 and Figure 2 As shown, in some embodiments, the liner 300 further includes a connecting rib 340, and the connecting plate 330 is connected to the annular wall 310 via the connecting rib 340.

[0055] The connecting plate 330 is connected to the annular wall 310 through the connecting rib 340 to form an integral structure, which facilitates molding and production.

[0056] Furthermore, the cross-sectional area of ​​the connecting rib 340 is smaller than that of the connecting plate 330, making the connecting rib 340 more prone to breakage than the connecting plate 330. It is easy to see that after the connecting rib 340 breaks, the connecting plate 330 can be moved away from the mounting plate 320, thereby ensuring that the breakage location is at the connecting rib 340 and avoiding damage to the connecting plate 330 caused by the breakage location.

[0057] like Figure 1 and Figure 4 As shown, in some embodiments, the outer side wall of the inner cover 200 is provided with a third protrusion 220, and the inner side wall of the liner 300 is provided with a fourth protrusion 350 corresponding to the third protrusion 220. The third protrusion 220 and the fourth protrusion 350 are spaced apart. When the inner cover 200 and the liner 300 rotate relative to each other by a certain distance, the third protrusion 220 can abut against the fourth protrusion 350.

[0058] In the stored state, the third protrusion 220 and the fourth protrusion 350 are spaced apart. When the bottle cap needs to be opened, the inner cap 200 and the liner 300 rotate relative to each other. During this process, the fourth protrusion 350 and the third protrusion 220 approach each other until the third protrusion 220 and the fourth protrusion 350 abut against each other. Continuously rotating the liner 300 or the inner cap 200 will make the inner cap 200 and the liner 300 rotate synchronously. This allows the anti-counterfeiting bottle cap to be opened after the RFID electronic tag 100 breaks.

[0059] It should be noted that the aforementioned "certain distance" refers to the distance between the third protrusion 220 and the fourth protrusion 350. When the third protrusion 220 and the fourth protrusion 350 abut against each other, continuing to rotate the inner cap 200 or the liner 300 will cause the liner 300 and the inner cap 200 to rotate synchronously, thus opening the bottle. Combining this with the aforementioned steps for opening the cap by rotation, it is easier to understand that after the RFID tag 100 breaks, the third protrusion 220 and the fourth protrusion 350 abut against each other to achieve synchronous rotation of the inner cap 200 and the liner 300, thereby opening the bottle. That is, during the relative rotation of the inner cap 200 and the liner 300 a certain distance, it is necessary to ensure that the RFID tag 100 breaks.

[0060] like Figure 1 and Figure 4 As shown, in some embodiments, the outer side wall of the inner cover 200 is provided with a relief groove 230, the third protrusion 220 is correspondingly provided with the relief groove 230, and the fourth protrusion 350 is provided in the relief groove 230 and can move along the relief groove 230.

[0061] A clearance groove 230 is formed at the top of the inner cover 200, and a fourth protrusion 350 is disposed within the clearance groove 230 and is movable along the clearance groove 230. Specifically, a third protrusion 220 is disposed on the path along which the fourth protrusion 350 moves along the clearance groove 230, forming as follows: Figure 4 The structure is shown. When the liner 300 and inner cover 200 need to be fitted together, the liner 300 is placed above the inner cover 200 and the two are coaxially arranged, so that the fourth protrusion 350 is located in the clearance groove 230. The liner 300 and inner cover 200 rotate relative to each other, so that the fourth protrusion 350 approaches the third protrusion 220 until the two abut against each other. Through the above arrangement, the fourth protrusion 350 can move within the clearance groove 230, thereby limiting the range of movement of the fourth protrusion 350, avoiding misalignment between the fourth protrusion 350 and the third protrusion 220, and the clearance groove 230 can provide positioning for the fourth protrusion 350. When the inner cover 200 and the liner 300 are fitted together, the operator can quickly align the fourth protrusion 350 with the clearance groove 230, improving the efficiency of the fitting and installation.

[0062] Furthermore, such as Figure 2 and Figure 4As shown, the outer side wall of the inner cover 200 is also provided with a fifth protrusion 240 corresponding to the third protrusion 220. The fifth protrusion 240 is also provided on the path of the fourth protrusion 350 moving along the relief groove 230. The fourth protrusion 350 and the fifth protrusion 240 abut against each other, so that the liner 300 and the inner cover 200 can rotate in the opposite direction of rotation when the fourth protrusion 350 abuts against the third protrusion 220. Specifically, when the fourth protrusion 350 rotates clockwise relative to the inner cap 200, it abuts against the third protrusion 220, causing both the liner 300 and the inner cap 200 to rotate clockwise, allowing the anti-counterfeiting cap to detach from the bottle opening. When the fourth protrusion 350 rotates counterclockwise relative to the inner cap 200, it abuts against the fifth protrusion 240, causing both the liner 300 and the inner cap 200 to rotate counterclockwise, allowing the anti-counterfeiting cap to be tightened at the bottle opening. By providing the fifth protrusion 240 to cooperate with the third protrusion 220, the liner 300 and the inner cap 200 can rotate synchronously in both directions, enabling the anti-counterfeiting cap to be tightened or unscrewed.

[0063] like Figure 1 and Figure 2 As shown, in some embodiments, the outer wall of the annular wall 310 is provided with a serrated structure 312, which is arranged along the circumferential direction of the annular wall 310.

[0064] In some preferred embodiments, the serrated structure 312 is provided along the outer periphery of the annular wall 310. This arrangement increases the friction when holding the cover 300, making it easier for the user to hold and rotate the cover 300, and preventing the user from slipping when holding the cover 300.

[0065] In some embodiments, the anti-counterfeiting bottle cap further includes an outer cap (not shown in the figure), which is fitted around the outer periphery of the liner 300 and is fixedly connected to the liner 300.

[0066] The outer cover is fitted around the outer periphery of the liner 300. Since the outer cover is fixedly connected to the liner 300, rotating the outer cover will cause the liner 300 to rotate. This allows the outer cover, located on the outermost side, to rotate the liner 300 relative to the inner cover 200, thereby causing the RFID electronic tag 100 to break. Through the above arrangement, the outer cover can protect the RFID electronic tag 100 located on the outer periphery of the liner 300, and at the same time, it can cause the liner 300 to rotate relative to the inner cover 200, thus achieving the purpose of damaging the RFID electronic tag 100 and opening the anti-counterfeiting bottle cap.

[0067] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0068] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
