Abstract
Description
Technical Field
[0001] This utility model belongs to the field of bottle cap technology, and in particular relates to an RFID chip anti-theft prize redemption bottle cap structure. Background Technology
[0002] Currently, wineries are offering prize redemption programs on their products to encourage consumer purchases. With the development of mobile internet and IoT technologies, more and more wineries are adopting RFID-based smart bottle caps for anti-counterfeiting and prize redemption. After normally opening the bottle cap, consumers can scan the RFID chip inside using their mobile phone's NFC function or a dedicated reader to read the prize information and claim a cash reward or points. Compared to traditional QR codes or printed codes, RFID technology has advantages such as difficulty in copying information and convenient and fast reading.
[0003] Due to the significant promotional efforts and substantial prizes offered by wineries, many criminals exploit the contactless reading capabilities of RFID technology. They use portable RFID readers to scan unopened bottle caps during the distribution process, obtaining winning information in advance. These criminals scan bottle caps in bulk at the wholesale and retail levels, selecting winning products for special redemption, or replacing non-winning products on shelves, severely damaging the legitimate rights and interests of consumers and wineries. Even more seriously, some criminals break the anti-counterfeiting structure by forcibly pulling or damaging the plastic hooks on the bottle caps, removing the entire cap, reading the winning information from the RFID chip, and then reattaching the cap with glue. Alternatively, they may replace the bottle with a different bottle and reassemble the cap, making it difficult to tell from the outside that the bottle has been tampered with or already redeemed. Consumers who purchase these altered products not only cannot redeem their prizes but may also receive counterfeit wine, leading to significant consumer resentment towards the wineries and severely damaging their brand reputation. Utility Model Content
[0004] To address the technical problems existing in the background art, this utility model provides an RFID chip anti-theft prize redemption bottle cap structure, which can effectively prevent criminals from opening the bottle cap to read the prize information or replace the wine by using abnormal methods such as forceful pulling or side pulling without damaging the anti-counterfeiting structure. At the same time, it can automatically trigger the RFID chip to enter the corresponding working mode, realizing the triple protection function of anti-theft scanning, anti-tampering, and anti-counterfeiting wine.
[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows: An RFID chip anti-theft prize redemption bottle cap structure includes an outer cap bottle sleeve assembly, which includes an inner sleeve and an outer sleeve. The inner sleeve is snapped onto the outer wall of the bottle mouth. An inner cap assembly is fitted inside the outer cap. The inner cap assembly includes an upper inner cap. An anti-counterfeiting identification component is provided at the top of the upper inner cap. The anti-counterfeiting identification component includes an RFID chip fixing ring, a middle ring body, and an outer ring body. The RFID chip fixing ring is connected to the middle ring body through several first breakable connecting parts. The middle ring body is connected to the outer ring body through several second breakable connecting parts. The outer end of the outer ring body is also provided with several bending parts. When the outer cover is rotated open, the first breakable connection can be broken under relative torsion, which is used to change the resonant frequency of the RFID chip to obtain the second resonant frequency. When the outer cover is forcibly pulled out, the second breakable connection can be broken under axial tensile force, which is used to change the resonant frequency of the RFID chip to obtain the third resonant frequency.
[0006] Optionally, the inner cover assembly also includes a lower inner cover that snaps into the inner wall of the outer cover. The top of the lower inner cover is snapped with a retaining ring. The lower inner cover is sleeved with the upper inner cover, and the tops of the lower inner cover, the retaining ring, and the upper inner cover are on the same plane.
[0007] Optionally, the top of the upper inner cover is fixedly connected to the RFID chip fixing ring, the top of the lower inner cover is fixedly connected to the middle ring body, the top of the retaining ring is fixedly connected to the outer ring body, and the outer wall of the retaining ring is fixedly connected to the bending part.
[0008] Optionally, the inner wall of the outer cover is locked to the outer wall of the lower inner cover by a snap-fit structure, and the inner wall of the upper inner cover is snapped to the inner sleeve by an anti-rotation structure.
[0009] Optionally, the snap-fit structure includes a lower snap-fit rib and an upper snap-fit rib fixedly connected to the inner wall of the outer cover. The upper snap-fit rib snaps with the bottom of the snap ring. The inner wall of the outer cover is also fixedly connected with a number of first anti-rotation teeth. The outer wall of the lower inner cover is provided with a third snap-fit rib that snaps with the lower snap-fit rib. The outer wall of the lower inner cover is provided with a lower anti-rotation tooth and an upper anti-rotation tooth. The lower anti-rotation tooth snaps with the first anti-rotation tooth. The inner wall of the snap ring is provided with a second anti-rotation tooth that snaps with the upper anti-rotation tooth. The anti-rotation structure includes a third anti-rotation tooth provided on the inner wall of the upper inner cover.
[0010] Optionally, the inner wall of the lower inner cover is threadedly connected to the outer wall of the inner sleeve. The inner sleeve includes a spout, which is integrally injection molded with the inner sleeve. The outer wall of the spout is provided with several anti-rotation plates that engage with the third anti-rotation tooth. The bottom of the inner wall of the inner sleeve engages with the bottle mouth, the top of the inner sleeve abuts against the upper inner cover, and the outer wall of the inner sleeve engages with the outer sleeve.
[0011] Optionally, the top of the outer cover has a transparent part, which is circular and has a diameter larger than the diameter of the RFID chip fixing ring but smaller than the diameter of the middle ring.
[0012] Optionally, the anti-counterfeiting identification component is integrally molded using an injection molding process, and the material of the anti-counterfeiting identification component is PP, PE or ABS plastic.
[0013] Optionally, both the first breakable connector and the second breakable connector have rectangular cross-sectional shapes.
[0014] This utility model has the following advantages and beneficial effects: In this invention, an anti-counterfeiting identification component is first installed at the top of the inner cover assembly. This component adopts a three-ring nested structure. The RFID chip fixing ring is connected to the middle ring body through a first breakable connection part, and the middle ring body is connected to the outer ring body through a second breakable connection part, forming a double breakage mechanism. During normal opening, the outer cover drives the lower inner cover and the retaining ring to rotate, while the upper inner cover remains stationary due to the anti-rotation structure. This causes the first breakable connection part to break due to relative rotation, shortening the antenna length and changing the resonant frequency from the first resonant frequency f1 to the second resonant frequency f2. The RFID chip automatically switches to the prize redemption information output mode, realizing the normal prize redemption function. When the outer cover is forcibly pulled out, the outer cover drives the retaining ring to move axially upwards, causing the second breakable connection part to break due to axial tension. The resonant frequency further shifts to the third resonant frequency f3. The chip determines this as an abnormal opening and automatically enters the anti-theft mode, permanently locking the prize redemption function and outputting a warning message. This method ensures that when criminals forcibly remove the bottle cap, not only will the second disconnectable connection be damaged, activating the anti-theft function, but more importantly, the RFID chip will automatically switch to anti-theft mode and permanently lock the prize redemption function. Even if normal opening is attempted later, the prize redemption status cannot be restored. Simultaneously, consumers can determine whether a product is illegitimate by simply tapping their mobile phone against the cap using NFC without opening the box. By combining a dual-break mechanism with the multi-frequency operating mode of the RFID chip, a combination of physical and electronic protection is achieved, enhancing the overall protection against theft, tampering, and counterfeit liquor, effectively safeguarding the legitimate rights and interests of both consumers and the winery.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.
[0018] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0019] Example like Figure 1 As shown, an RFID chip anti-theft prize redemption bottle cap structure includes components such as a bottle mouth, an inner plug 7, and an anti-counterfeiting ring 8.
[0020] like Figures 1 to 7As shown, an RFID chip anti-theft prize redemption bottle cap structure also includes an outer cap 1 and a bottle sleeve assembly. The bottle sleeve assembly includes an inner sleeve 31 and an outer sleeve 32. The inner sleeve 31 is snapped onto the outer wall of the bottle mouth. An inner cap assembly is fitted inside the outer cap 1. The inner cap assembly includes an upper inner cap 43, forming a multi-layer nested structure. An anti-counterfeiting identification component 2 is provided at the top of the upper inner cap 43. The anti-counterfeiting identification component 2 includes an RFID chip fixing ring 21, a middle ring body 22, and an outer ring body 23. The RFID chip fixing ring 21 is fixedly connected to the middle ring body 22 through several first breakable connecting parts 24. The middle ring body 22 is fixedly connected to the outer ring body 23 through several second breakable connecting parts 25. The outer end of the outer ring body 23 is also provided with several bending parts 26. The bending parts 26 are flush with the outer ring body 23 before installation.
[0021] The RFID chip fixing ring 21, the middle ring body 22, the outer ring body 23, the first disconnectable connection part 24, and the second disconnectable connection part 25 all adopt a double-layer structure. The interlayer of the RFID chip fixing ring 21 is used to install the passive RFID chip, and the upper surface of the RFID chip fixing ring 21 is used to print the QR code. The interlayer of the middle ring body 22, the outer ring body 23, the first disconnectable connection part 24, and the second disconnectable connection part 25 is used to pre-embed the antenna coil. The interlayer structure can completely encapsulate the RFID chip and the antenna, preventing moisture, dust, and mechanical damage. The antenna coil is in a fixed position and will not be affected by external deformation, thus preventing information tampering. Once encapsulation is completed, the chip cannot be accessed without damaging the structure.
[0022] like Figures 3-4 As shown, the inner cover assembly further includes a lower inner cover 41 that snaps into the inner wall of the outer cover 1. A retaining ring 42 is snapped into the top of the lower inner cover 41. The lower inner cover 41 is sleeved with the upper inner cover 43. The tops of the lower inner cover 41, the retaining ring 42, and the upper inner cover 43 are on the same plane. The tops of the three components are flush to form a complete plane, which facilitates the installation of the anti-counterfeiting identification component 2, avoids stress concentration caused by unevenness, ensures that the RFID chip antenna is parallel to the reading device, and guarantees reading performance.
[0023] Furthermore, the top of the upper inner cover 43 is glued to the RFID chip fixing ring 21 with strong adhesive, the top of the lower inner cover 41 is glued to the middle ring body 22 with strong adhesive, the top of the retaining ring 42 is glued to the outer ring body 23 with strong adhesive, and the outer wall of the retaining ring 42 is also glued to the bending part 26 with strong adhesive. This can prevent the RFID chip fixing ring 21 from being pulled up when the first breakable connecting part 24 and the second breakable connecting part 25 break.
[0024] like Figures 3-7As shown, further, the inner wall of the outer cover 1 is locked to the outer wall of the lower inner cover 41 by a snap-fit structure, and the inner wall of the upper inner cover 43 is snapped to the inner sleeve 31 by an anti-rotation structure, restricting the circumferential rotation and axial movement of the outer cover 1. Under normal conditions, when the bottle cap is sensed by the mobile phone NFC, the resonant frequency is the first resonant frequency f1, and the passive RFID chip outputs the preset promotional information. At this time, the winning information cannot be read. Even after the criminals scan in batches, they still cannot filter the winning products. Consumers can verify the authenticity of the product by reading the promotional information. Counterfeit products cannot output the correct information. In the retail process, consumers do not need to open the box or the cap. They can use their mobile phone NFC to sense the outside of the wine box. If the mobile phone displays a status such as "scanned / invalid / abnormal", or the mobile phone cannot sense the chip signal outside the box, it is determined to be an abnormal product (including stolen or suspected counterfeit wine). The store and consumers can be prompted "Do not purchase".
[0025] When a consumer rotates the outer cover 1 normally, the outer cover 1 drives the lower inner cover 41 and the retaining ring 42 to rotate synchronously. The upper inner cover 43 remains stationary due to the restriction of the anti-rotation structure. This causes the first breakable connection 24 between the RFID chip fixing ring 21 and the middle ring body 22 to break due to relative rotation. The antenna length shortens, and the resonant frequency changes to the second resonant frequency f2. The passive RFID chip automatically switches to the prize redemption information output mode. The mobile phone enters the prize redemption page. Once the first breakable connection 24 breaks, it cannot be repaired to its original state, and the antenna length cannot be restored. This ensures that each bottle cap can only be activated once. After the mobile phone receives the second resonant frequency f2 frequency signal and the prize redemption information, it can verify with the server whether the chip ID is for the first prize redemption, preventing chip cloning.
[0026] When the outer cover 1 is forcibly pulled out, the outer cover 1 can drive the retaining ring 42 to move upward axially, causing the second breakable connection 25 between the middle ring 22 and the outer ring 23 to break due to axial tension. The resonant frequency further shifts to the third resonant frequency f3. After the resonant frequency becomes the third resonant frequency f3, the internal logic unit of the chip judges it as an abnormal opening and violent destruction, automatically enters the anti-theft mode, and permanently locks the prize redemption function. At the same time, the chip outputs warning messages such as "invalid", "suspected tampering", and "please contact the manufacturer" to the mobile phone. Consumers can immediately identify that the product has been illegally opened. After the second breakable connection 25 breaks, even if someone tries to open it normally by rotating it and then break the first breakable connection 24, the chip will still remain in the anti-theft mode and cannot switch back to the prize redemption mode.
[0027] like Figures 6-7As shown, the snap-fit structure further includes a lower snap-fit rib 51 and an upper snap-fit rib 52 fixedly connected to the inner wall of the outer cover 1. The upper snap-fit rib 52 snaps with the bottom of the snap ring 42. The inner wall of the outer cover 1 is also fixedly connected with a plurality of first anti-rotation teeth 53. The outer wall of the lower inner cover 41 is provided with a third snap-fit rib 54 that snaps with the lower snap-fit rib 51. The outer wall of the lower inner cover 41 is provided with a lower anti-rotation tooth 55 and an upper anti-rotation tooth 56. The lower anti-rotation tooth 55 snaps with the first anti-rotation tooth 53. The inner wall of the snap ring 42 is provided with a second anti-rotation tooth 57 that snaps with the upper anti-rotation tooth 56. The anti-rotation structure includes a third anti-rotation tooth 58 provided on the inner wall of the upper inner cover 43.
[0028] When the consumer opens the outer cap 1 normally, the lower locking rib 51 and the third locking rib 54 are engaged, restricting the axial movement of the outer cap 1, which can only rotate circumferentially. When the outer cap 1 is rotated, the first anti-rotation tooth 53 on the outer cap 1 engages with the lower anti-rotation tooth 55, and the outer cap 1 drives the lower inner cap 41 to rotate synchronously. The threads of the lower inner cap 41 and the inner sleeve 31 are loosened, while the third anti-rotation tooth 58 on the upper inner cap 43 is engaged with the inner sleeve 31 and cannot rotate, keeping the RFID chip fixing ring 21 stationary. Since the upper locking rib 52 is engaged with the bottom of the retaining ring 42, and the second anti-rotation tooth 57 on the inner wall of the retaining ring 42 engages with the upper anti-rotation tooth 56, when the bottle cap is rotated open, the retaining ring 42 rises and rotates together with the outer cap 1, thereby driving the middle ring body 22 and the outer ring body 23 to rotate together, twisting off the first breakable connecting part 24. Then, the lower inner cap 41 can be removed to pour out the wine.
[0029] When opened normally, the outer cover 1 destroys the anti-counterfeiting teeth 9 fixed at the top of the outer cover 32, and the notch on the outer cover 1 exposes the words "opened" on the anti-counterfeiting ring 8, further warning consumers.
[0030] When criminals forcibly pull out the outer cover 1, the connection between the lower locking rib 51 inside the outer cover 1 and the third locking rib 54 outside the lower inner cover 41 is damaged. The outer cover 1 moves upward axially, preventing the anti-counterfeiting tooth 9 from being damaged. However, as the outer cover 1 moves upward, the upper locking rib 52 on the outer cover 1 will drive the retaining ring 42 to rise together, thereby breaking the second breakable connection 25 between the outer ring body 23 and the middle ring body 22.
[0031] Furthermore, the inner wall of the lower inner cover 41 is threadedly connected to the outer wall of the inner sleeve 31. The inner sleeve 31 includes a spout 33 and a snap-fit portion 35, such as... Figure 1As shown, a fastener 36 is embedded inside the snap-fit part 35, and a fourth anti-rotation tooth 37 is also provided at the bottom of the inner wall of the inner sleeve 31. When the inner sleeve 31 is put on the outer wall of the bottle mouth, the fastener 36 drives the snap-fit part 35 to be embedded in the groove of the outer wall of the bottle mouth for axial positioning. At the same time, the fourth anti-rotation tooth 37 is engaged with the anti-rotation tooth of the outer wall of the bottle mouth for circumferential positioning. The spout 33 and the inner sleeve 31 are integrally injection molded. The outer wall of the spout 33 is provided with several anti-rotation pieces 34 that engage with the third anti-rotation tooth 58. The anti-rotation pieces 34 can prevent the upper inner cover 43 from rotating. The top of the inner sleeve 31 abuts against the upper inner cover 43, and the outer wall of the inner sleeve 31 is engaged with the outer sleeve 32.
[0032] Furthermore, the top of the outer cover 1 is provided with a transparent part 6, which is circular. The diameter of the transparent part 6 is larger than the diameter of the RFID chip fixing ring 21 but smaller than the diameter of the middle ring 22. This prevents criminals from seeing the overall structure of the anti-counterfeiting identification component 2, allowing them to see only the QR code. This further prevents criminals from cracking the anti-counterfeiting identification component 2. At the same time, consumers can scan the code through the transparent part 6 to obtain relevant product information. In addition, the supporting RFID solution supports consumers to use their mobile phones for NFC near-field sensing on the outside of the box for pre-purchase verification. If an abnormal status such as "already scanned / expired" is read or the chip cannot be sensed on the outside of the box, the consumer will be prompted "Do not purchase".
[0033] Furthermore, the anti-counterfeiting identification component 2 is integrally molded using injection molding technology. Integral molding can ensure the continuity of materials and prevent weak points at the interface. The material of the anti-counterfeiting identification component 2 is PP, PE or ABS plastic.
[0034] Furthermore, the cross-sectional shape of both the first breakable connecting part 24 and the second breakable connecting part 25 is rectangular. When the rectangular cross-section breaks, the corners crack first to form an irregular tear surface. After adhesive repair, the fit is poor and there are gaps visible to the naked eye, which prevents criminals from tampering with it and restoring it.
[0035] During assembly, assemble the top of the upper inner cover 43 with the top of the inner sleeve 31, insert the lower inner cover 41 into the outer wall of the inner sleeve 31, and snap the retaining ring 42 onto the top of the lower inner cover 41. Then, snap the assembled anti-counterfeiting ring 8 onto the inner sleeve 31. Next, place the anti-counterfeiting identification component 2 as a whole in the center of the upper inner cover 43 and stick it with strong adhesive. Then, snap the outer cover 1 into the outer end of the lower inner cover 41. When the outer cover 1 is snapped on, the inner wall of the outer cover 1 will bend the bending part 26, so that the bending part 26 is firmly attached to the outer wall of the retaining ring 42. Finally, assemble the whole assembly from the top of the outer sleeve 32 from top to bottom.
[0036] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
