Description

Technical Field

[0001] This application relates to the field of anti-counterfeiting technology for packaging boxes, and in particular to a novel anti-counterfeiting buckle. Background Technology

[0002] In the field of packaging anti-counterfeiting technology, as consumers increasingly focus on product authenticity and packaging integrity, effectively preventing counterfeit and substandard products has become a crucial issue for the industry. This is especially true for high-end gifts, artwork, and alcoholic beverages, where the sealing and anti-counterfeiting performance of the packaging directly impacts the product's market value and brand image. While traditional anti-counterfeiting technologies have improved packaging security to some extent, their designs often struggle to balance ease of opening and packaging integrity, thus limiting the improvement of user experience.

[0003] To address these issues, common industry practices currently include using tape, adhesives, or physical locking mechanisms. While tape and adhesives achieve sealing through bonding, they are easily resealed, offering limited anti-counterfeiting effectiveness. Physical locking mechanisms, such as buckles or locks, mechanically secure the packaging box, providing better anti-counterfeiting performance, but often damage the box upon opening, hindering reuse. Furthermore, these methods may leave residues during opening, causing contamination and affecting aesthetics.

[0004] However, these existing technologies generally share a common drawback: while ensuring the packaging box's airtightness, they cannot achieve easy, damage-free opening, thus affecting user experience and the box's reusability. This contradiction urgently requires a solution that can both guarantee airtightness and enable easy, damage-free opening. Utility Model Content

[0005] The purpose of this application is to provide a new type of anti-counterfeiting buckle.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution: a novel anti-counterfeiting buckle, comprising a bursting ring, a pin, and a sleeve; the middle part of the bursting ring has an easily detachable structure; the pin comprises a head and a rod, the diameter of the head being larger than the inner diameter of the bursting ring, and a spring piece being provided on the rod; the sleeve comprises a base and a hyperbolic retaining ring, the base being used to fix it inside the packaging box, the hyperbolic retaining ring being disposed on the base, and the bursting ring being placed inside the hyperbolic retaining ring.

[0007] By adopting the above technical solution, the easily breakable structure of the bursting ring allows the sealing structure to be easily broken when the rivet is inserted. The hyperbolic rivet opens after the bursting ring breaks, which does not hinder the initial insertion and removal of the rivet, and can also lock the rivet in place after the bursting ring is removed to achieve a firm seal. This balances the reliability of the packaging box when sealed and the convenience of opening. The diameter of the rivet head is larger than the inner diameter of the bursting ring and works with the spring clip on the rod to ensure that the broken bursting ring is pulled out simultaneously when the rivet is pulled out, avoiding residue contamination of the inside of the packaging box. The overall structural design enables the packaging box to be opened without damage, which not only ensures the anti-counterfeiting performance in the sealed state, but also avoids the packaging damage caused by opening in traditional sealing methods, effectively improving the aesthetics and user experience of high-end product packaging.

[0008] Optionally, the middle part of the bursting ring has a thickness less than that at both ends, forming a fracture groove.

[0009] By adopting the above technical solution, the middle part of the bursting ring is designed to be thinner than the two ends, forming a fracture groove. This structural differentiation weakens the strength of the middle area, making it a pre-designed weak point. This allows for precise control of the fracture location and reduces the external force required for fracture, ensuring that the bursting ring can stably break from the middle when the clip is inserted. This avoids sealing failure or difficulty in opening due to uncontrollable fracture location or excessive strength. The fracture groove provides a clear fracture guidance path for the bursting ring, improving the reliability and consistency of the breaking process. Combined with the pressure of the clip head, it can achieve a complete fracture without residue. At the same time, it simplifies the processing technology of the bursting ring. The standardized design of the thickness difference or groove structure facilitates mass production and quality control, further ensuring the stability and practicality of the anti-counterfeiting buckle in practical applications.

[0010] Optionally, the bursting ring has a plurality of fracture openings formed in the fracture groove.

[0011] By adopting the above technical solution, several hollow fracture openings are set at the fracture groove, further weakening the structural strength of the middle part of the bursting ring and making this area a more significant weak point. This allows for precise fracture with less external force when pressure is applied to the head of the clip, ensuring a fast and stable fracture process. The hollow design of the fracture openings forms a preset stress concentration point, guiding the bursting ring to break along a specific path, avoiding randomness in the fracture location and improving the reliability of the anti-counterfeiting buckle. At the same time, after the bursting ring breaks, the hollow fracture openings can form a more effective cooperation with the spring piece on the clip rod, facilitating the complete removal of fragments when the clip is pulled out, eliminating the risk of residue remaining in the packaging box. This not only ensures the one-time destruction characteristic of the sealed structure to achieve the anti-counterfeiting function, but also improves the cleanliness and user experience during use through structural optimization.

[0012] Optionally, the hyperbolic retaining ring includes two opposing arc-shaped retaining arms, with an annular space between the two arc-shaped retaining arms for accommodating the bursting ring.

[0013] By adopting the above technical solution, the two opposing arc-shaped arms of the hyperbolic retaining ring form an annular space, providing precise positioning and accommodating space for the bursting ring, ensuring stable installation and uniform force distribution of the bursting ring within the retaining sleeve. The elastic structure of the arc-shaped arms allows them to open under external force after the bursting ring breaks, without interfering with the initial insertion and multiple insertions and removals of the rivet. Simultaneously, after the bursting ring is removed, its own deformation can lock the rivet rod, forming a reliable mechanical lock and achieving a sealed state for the packaging box. This annular space design not only provides the necessary space for the bursting ring to break but also optimizes the fit between the retaining ring and the rivet through the mechanical properties of the arc structure. This makes the pressure transmission during rivet insertion smoother and the spring linkage during removal more efficient. Thus, while ensuring anti-counterfeiting functionality, it improves the stability of the buckle operation and the user experience, avoiding the rivet jamming or sealing failure problems caused by the lack of elasticity in traditional rigid retaining rings.

[0014] Optionally, the bursting ring is provided with a limiting element.

[0015] By adopting the above technical solution, the limiting component on the bursting ring can form a precise fit with the ferrule base, ensuring the positioning accuracy of the bursting ring within the hyperbolic ferrule. This avoids issues such as fracture position deviation or uneven force due to installation misalignment, thus ensuring that the pressure applied when the ferrule is inserted is accurately applied to the easily breakable structure of the bursting ring. The design of the limiting component effectively prevents the bursting ring from shifting or falling off during packaging, transportation, or storage, improving the overall stability of the anti-counterfeiting buckle structure. It also provides installation guidance for the bursting ring, simplifying the assembly process and facilitating standardized installation during mass production. Furthermore, the fitting between the limiting component and the base enhances the stress stability of the bursting ring during fracture, ensuring that it breaks along a preset path and maintains controllable movement trajectory when pulled out with the ferrule after breakage, preventing fragments from remaining or the ferrule from jamming. This further optimizes the reliability of the anti-counterfeiting buckle and the user experience.

[0016] Optionally, the base has a recessed mounting groove on the side away from the hyperbolic retaining ring, and the limiting member can be fitted into the mounting groove.

[0017] By adopting the above technical solution, the fitting design of the mounting groove on the base and the bursting ring limiting component forms a precise mechanical positioning structure, ensuring that the installation position of the bursting ring within the hyperbolic retaining ring is fixed and unique, effectively avoiding uneven force or breakage failure caused by displacement. The concave mounting groove provides a stable fitting space for the limiting component, enhancing the connection strength of the bursting ring in the retaining sleeve, making it less prone to displacement or detachment when the packaging box is subjected to external impact or long-term use, ensuring the reliability of the anti-counterfeiting buckle in a sealed state. At the same time, this standardized fitting structure simplifies the assembly process, facilitates rapid positioning and installation during production, improves manufacturing efficiency, and the cooperation between the limiting component and the mounting groove provides a stable support foundation for the bursting ring's fracture process, ensuring that the pressure of the retaining pin can be accurately transmitted to the easily breakable structure, achieving stable fracture along the preset path, avoiding fragment retention or retaining ring jamming, further optimizing the structural stability and user experience of the anti-counterfeiting buckle.

[0018] Optionally, the head is provided with a guide surface.

[0019] By adopting the above technical solutions, the guide surface design of the rivet head can form a guiding inclined or arc-shaped structure during insertion, effectively reducing the insertion resistance between the rivet and the hyperbolic retaining ring or bursting ring, avoiding jamming or offset problems caused by rigid contact, and enabling the rivet to quickly and accurately align with the easily breakable structure of the bursting ring; the tilt angle or arc contour of the guide surface can guide the pressure of the rivet head to be evenly applied to the middle part of the bursting ring, ensuring that it breaks stably along the preset path and improving the reliability of the breaking process; at the same time, the guide surface design optimizes the user's operating experience, making the insertion action smoother and less strenuous, especially suitable for high-end packaging scenarios that require ease of operation and structural refinement, avoiding packaging damage or sealing failure caused by insertion difficulties, and further enhancing the practicality and market applicability of the anti-counterfeiting buckle.

[0020] Optionally, the spring clips are provided in multiple quantities.

[0021] By adopting the above technical solution, the multiple spring clips on the rivet rod can form a multi-point contact clamping structure. Compared with a single or two spring clips, this provides a more balanced clamping force and a stronger linkage effect, ensuring that the broken bursting ring and its fragments can be stably and reliably pulled out when the rivet is pulled out, avoiding clamping failure or residue retention due to insufficient number of spring clips. The distribution design of the multiple spring clips can be flexibly adjusted according to the size and fracture pattern of the bursting ring, enhancing the adaptability to bursting rings of different specifications and improving the versatility of the anti-counterfeiting buckle. At the same time, the multi-point contact structure can evenly distribute the pulling force during the pulling process, reducing the frictional resistance between the rivet and the hyperbolic rivet, making the operation smoother and less strenuous, avoiding rivet deformation or bursting ring fragment breakage due to uneven force, further ensuring the integrity and reliability of the anti-counterfeiting buckle during the opening process, and effectively achieving a clean opening effect without residue.

[0022] In summary, this application has at least the following beneficial effect:

[0023] 1. The easily breakable structure of the burst ring allows the rivet to easily break the seal when inserted. The hyperbolic rivet opens after the burst ring breaks, which does not hinder the initial insertion and removal of the rivet, and can also hold the rivet securely after the burst ring is removed, thus balancing the reliability of the packaging box's seal with the ease of opening. The rivet head diameter is larger than the inner diameter of the burst ring, and in conjunction with the spring clip on the rod, it ensures that the broken burst ring is pulled out simultaneously when the rivet is removed, preventing residue from contaminating the inside of the packaging box. The overall structural design enables the packaging box to be opened without damage, ensuring the anti-counterfeiting performance in the sealed state, and avoiding the packaging damage caused by opening in traditional sealing methods, effectively improving the aesthetics and user experience of high-end product packaging.

[0024] 2. The middle section of the bursting ring is designed to be thinner than the two ends, forming a fracture groove. This structural differentiation weakens the strength of the middle area, making it a pre-designed weak point. This allows for precise control of the fracture location and reduces the external force required for fracture, ensuring that the bursting ring can stably break from the middle when the clip is inserted. This avoids sealing failure or difficulty in opening due to uncontrollable fracture location or excessive strength. The fracture groove provides a clear fracture guide path for the bursting ring, improving the reliability and consistency of the breaking process. Combined with the pressure from the clip head, it achieves a complete fracture without residue. At the same time, it simplifies the processing technology of the bursting ring. The standardized design of the thickness difference or groove structure facilitates mass production and quality control, further ensuring the stability and practicality of the anti-counterfeiting clip in actual applications.

[0029] The present application will be further described in detail below with reference to the accompanying drawings.

[0030] Example 1, in this example, refers to Figures 1-2A novel anti-counterfeiting buckle includes a bursting ring 1, a clip 2, and a sleeve 3; the middle part of the bursting ring 1 has an easily detachable structure; the clip 2 includes a head 4 and a rod 5, the diameter of the head 4 is larger than the inner diameter of the bursting ring 1, and a spring piece 6 is provided on the rod 5; the sleeve 3 includes a base 7 and a hyperbolic retaining ring 8, the base 7 is used to fix it inside the packaging box, the hyperbolic retaining ring 8 is set on the base 7, and the bursting ring 1 is placed inside the hyperbolic retaining ring 8.

[0031] Specifically, the bursting ring 1 includes a middle section and two end sections. The thickness of the middle section is less than that of the end sections, forming a fracture groove 9. This structural design makes it easier for the bursting ring 1 to fracture from the middle under stress without affecting the strength of the end sections. Furthermore, the fracture groove 9 has hollow spaces forming several fracture openings 10, further reducing the energy required for fracture and ensuring reliable fracture of the bursting ring 1. The bursting ring 1 can be made of flexible materials such as polypropylene to improve its fracture performance.

[0032] The clip 2 includes a head 4 and a rod 5. The diameter of the head 4 is larger than the inner diameter of the bursting ring 1, ensuring that the bursting ring 1 can split open when the clip 2 is inserted, facilitating the removal of the bursting ring 1 by the subsequent spring piece 6. The head 4 has a guide surface 13, which reduces resistance during insertion and makes the operation smoother. The rod 5 is equipped with a spring piece 6. The number of spring pieces 6 can be selected according to actual needs, with two spring pieces selected based on the diameter and length of the clip 2. The spring pieces 6 can be made of spring steel or stainless steel, and their shape can be designed as curved or straight to adapt to different usage scenarios.

[0033] The sleeve 3 includes a base 7 and a hyperbolic retaining ring 8. The base 7 is used to secure the sleeve inside the packaging box, and can be fixed via threaded connection or snap-fit ​​connection. The hyperbolic retaining ring 8 includes two opposing arc-shaped retaining arms, forming an annular space between the two arc-shaped retaining arms to accommodate the bursting ring 1. The two arc-shaped retaining arms stably clamp and install the bursting ring 1. The arc-shaped retaining arms can be made of metal or high-strength plastic to ensure sufficient elastic deformation capacity. The cross-section of the arc-shaped retaining arms can be designed as circular or elliptical to optimize stress distribution. Furthermore, the dimensions of the hyperbolic retaining ring 8 need to be adjusted according to the size of the bursting ring 1 to ensure the precision of the fit between the two.

[0034] The bursting ring 1 is provided with a limiting member 11, which can be fitted into the recessed mounting groove 12 on the side of the base 7 away from the hyperbolic retaining ring 8. The function of the limiting member 11 is to prevent the bursting ring 1 from moving when the retaining pin 2 is not inserted, ensuring its accurate position. The limiting member 11 can be designed in a square shape, and the material can be plastic or metal, depending on the actual requirements.

[0035] The implementation principle of this embodiment is as follows: The sleeve 3 is fixed inside the packaging box by the base 7. The annular space of the hyperbolic retaining ring 8 provides a precise installation position for the bursting ring 1. With the engagement of the limiting member 11 on the bursting ring 1 and the mounting groove 12 of the base 7, the bursting ring 1 is fixed in position within the sleeve 3 and subjected to uniform force. When the pin 2 is inserted into the hyperbolic retaining ring 8 from outside the packaging box, the design of the head 4 having a diameter larger than the inner diameter of the bursting ring 1 causes it to first contact the middle of the bursting ring 1. The applied pressure is concentrated on the easily breakable structure, causing the bursting ring 1 to break along a preset weak area (such as the fracture groove 9 or the fracture opening 10). The broken fragments of the bursting ring 1 press outward against the arc-shaped retaining arm of the hyperbolic retaining ring 8, causing it to open elastically, releasing the clamping restriction on the pin 2, allowing the pin 2 to be pulled out freely, achieving unobstructed operation during the first opening. The spring clip 6 on the rod 5 of the clip 2 plays a crucial role in the removal process. Because the diameter of the head 4 is larger than the inner diameter of the bursting ring 1, the broken fragments cannot fall off directly. The spring clip 6 uses the clamping force generated by elastic deformation or the hook-like structure to carry the fragments out simultaneously with the clip 2, avoiding residue inside the packaging box and solving the contamination problem of traditional sealing methods. When the product is placed in the packaging box and the clip 2 is inserted again, because the bursting ring 1 has been removed, the arc-shaped clamping arm of the hyperbolic retaining ring 8 returns to its initial elastic state, using its own deformation to clamp the head 4 of the clip 2, forming a stable mechanical lock. At this time, the engagement between the sleeve 3 and the clip 2 does not rely on the bursting ring 1. The seal is achieved through the elastic clamping of the hyperbolic retaining ring 8, ensuring that the packaging box remains closed during transportation or storage, while retaining its non-destructive characteristics when opened later.

[0036] Example 2 differs from the previous example in that the arc-shaped retaining arm of the hyperboloid retaining ring 8 incorporates an anti-slip texture design. The anti-slip texture increases the friction between the retaining pin 2 and the hyperboloid retaining ring 8, thereby improving sealing performance. The anti-slip texture can be designed as a diamond grid or a wave pattern. Furthermore, the thickness of the arc-shaped retaining arm can be appropriately increased to enhance its load-bearing capacity.

[0037] The implementation principle of this embodiment is as follows: by adding an anti-slip texture design, the fitting accuracy between the clip 2 and the hyperboloid retaining ring 8 is further improved, enhancing the sealing performance. At the same time, the increased thickness of the arc-shaped retaining arm ensures its stability during long-term use, extending its service life.

[0038] Example 3 differs from the previous examples in that the fracture groove 9 of the bursting ring 1 is designed in a spiral shape. The function of the spiral fracture groove 9 is to guide the bursting ring 1 to fracture in a specific direction when subjected to force, preventing fragments from scattering. The angle of the spiral fracture groove 9 can be designed to be 30 degrees or 45 degrees. In addition, the material of the bursting ring 1 can be a biodegradable material to reduce environmental pollution.

[0039] The implementation principle of this embodiment is as follows: the spiral fracture groove 9 design not only improves the fracture reliability of the bursting ring 1, but also effectively reduces the risk of fragment scattering. At the same time, the application of biodegradable materials reflects the concept of environmental protection and meets the requirements of sustainable development.

[0040] Example 4 differs from the previous examples in that a marking area is added to the head 4 of the rivet 2. The marking area serves to record production information or anti-counterfeiting codes for easy traceability and verification. The marking area can be created using laser engraving or inkjet printing technology. Furthermore, the marking area can be positioned on the top or side of the head 4 to suit different usage scenarios.

[0041] The implementation principle of this embodiment is as follows: by adding a labeling area design, the traceability and anti-counterfeiting functions of the product are realized, further improving the safety and reliability of the product.

[0042] Example 5

[0043] The difference between this embodiment and the previous embodiment is that a shock-absorbing washer is added to the base 7 of the card sleeve 3. The function of the shock-absorbing washer is to absorb external impact and protect the contents of the packaging box. The shock-absorbing washer can be made of silicone or rubber. Furthermore, the thickness of the shock-absorbing washer can be adjusted according to the size of the packaging box to ensure a tight fit between it and the base 7.

[0044] The implementation principle of this embodiment is as follows: by adding shock-absorbing pads, the overall protective performance of the packaging box is effectively improved, especially during transportation and storage, it can better protect the contents from damage.

[0045] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
