Description

Technical Field

[0001] This utility model relates to the field of novel anti-counterfeiting wine cap technology, specifically, to a two-piece anti-counterfeiting wine cap. Background Technology

[0002] In the field of alcoholic beverage packaging, bottle caps, as core components, must simultaneously meet multiple requirements such as sealing and preservation, anti-counterfeiting and traceability, brand display, and convenient use by consumers. Currently, most conventional alcoholic beverage bottle caps on the market adopt a modular structure, which usually contains multiple independent parts, resulting in a large number of parts.

[0003] Such modular bottle caps have significant limitations in actual production and application: On the one hand, the multi-component design leads to complex assembly processes, requiring multiple steps to assemble each component sequentially. This not only increases equipment investment and operation time on the production line but also raises the incidence of quality problems such as component misalignment and omissions due to the increased number of assembly steps, thus reducing production efficiency. On the other hand, the multi-component structure inevitably increases raw material procurement and processing costs, and the high precision requirements between components further drive up overall production costs, making it difficult for companies to control product costs and enhance market competitiveness.

[0004] Therefore, how to simplify the bottle cap structure, reduce the number of parts, thereby reducing assembly complexity and production costs, while improving production efficiency, without affecting the bottle cap's sealing performance, anti-counterfeiting function, brand display effect, and ease of use, has become a pressing technical problem for the current wine packaging industry. Utility Model Content

[0005] The present invention aims to provide a two-piece anti-counterfeiting wine cap to solve the problem in the prior art of how to reduce the number of parts, improve efficiency and reduce costs while ensuring functionality.

[0006] The embodiments of this utility model are implemented as follows: This utility model embodiment provides a two-piece anti-counterfeiting wine cap, which includes an outer cap and a double anti-counterfeiting inner cap; The outer cap is assembled downwards and fastened to the upper end of the double anti-counterfeiting inner cap. The assembly of the outer cap and the double anti-counterfeiting inner cap is press-fitted onto the bottle mouth, which has external threads, a flange, and a sealing surface. The outer cover has a cavity, a raised strip, and a retaining ring. The cavity is fitted over the upper part of the double anti-counterfeiting inner cover, and the raised strip is axially arranged along the inner wall of the cavity. The aforementioned double anti-counterfeiting inner cover is provided with anti-rotation ribs, annular grooves, limiting steps, internal threads, folded skirts, sealing cylindrical surfaces, anti-theft rings, transparent gaskets, and the inner surface of the top plate. The aforementioned anti-rotation ribs and the aforementioned protrusions are mutually adapted to prevent rotation, the aforementioned annular grooves are adapted to the aforementioned retaining rings for fastening, and the bottom end of the aforementioned outer cover abuts against the aforementioned limiting steps. The aforementioned anti-theft ring has a connection point and a ring body, wherein the connection point is used to connect the ring body to the aforementioned double anti-counterfeiting inner cover body; The aforementioned transparent gasket is injection molded in two colors inside the aforementioned double anti-counterfeiting inner cover. The inner surface of the aforementioned top plate has an inner code, and the inner code is data-linked with the outer code on the top of the aforementioned outer cover.

[0007] During assembly, the outer cap is first aligned and fitted onto the upper end of the double anti-counterfeiting inner cap, so that the upper structure of the double anti-counterfeiting inner cap gradually enters the cavity of the outer cap. During this process, the protrusions on the inner wall of the cavity correspond and match the anti-rotation ribs of the double anti-counterfeiting inner cap. After the retaining ring of the outer cap is elastically deformed, it is embedded in the annular groove of the double anti-counterfeiting inner cap until the bottom end of the outer cap abuts against the limiting step of the double anti-counterfeiting inner cap, thus completing the snap-fit ​​and fixing of the outer cap and the double anti-counterfeiting inner cap, forming a two-piece anti-counterfeiting wine cap assembly. The assembly is then aligned with the bottle opening and pressed downwards. The assembly is pressed downwards gradually until the sealing cylindrical surface of the double anti-counterfeiting inner cap is tightly fitted with the sealing surface of the bottle opening. At the same time, the folded skirt of the double anti-counterfeiting inner cap is folded by the edge of the bottle opening and snaps onto the edge. The internal thread of the double anti-counterfeiting inner cap engages with the external thread of the bottle opening, completing the assembly of the cap and the bottle opening.

[0008] This embodiment discloses a two-piece anti-counterfeiting bottle cap. Due to its streamlined two-piece structure consisting of an outer cap and a double anti-counterfeiting inner cap, it significantly reduces the number of parts compared to traditional multi-part bottle caps, simplifying the assembly process and lowering production and assembly costs. Simultaneously, the outer cap handles aesthetic decoration and brand display, while the double anti-counterfeiting inner cap integrates sealing, physical anti-counterfeiting, and digital traceability functions, achieving clear and comprehensive functional zoning. Specifically, when the bottle cap does not require brand display, the decorative outer cap is unnecessary; the double anti-counterfeiting inner cap alone can achieve sealing, connection, and physical information anti-counterfeiting. Furthermore, the large-lead four-thread design of the double anti-counterfeiting inner cap, combined with the anti-misfit design of the outer cap and the double anti-counterfeiting inner cap, further enhances its functionality. The design allows for easy opening with a simple 90° counter-rotation, enhancing the user experience. The interlocking of the folded skirt with the bottle neck's edge, and the interference fit between the sealing cylinder and the bottle neck's sealing surface, provide double protection for sealing performance and assembly stability. The fragile connection point design of the anti-theft ring ensures it cannot be restored after opening, achieving physical anti-counterfeiting. The dual-color injection-molded transparent gasket, combined with the data association between the inner code and the outer code on the cap, further enables digital traceability. This comprehensively meets the core needs of wine bottle caps for cost, safety, branding, and digitalization, resulting in a two-piece anti-counterfeiting wine cap that, while maintaining functionality, reduces the number of parts, improves production efficiency, and lowers production costs.

[0009] Optionally, the internal thread of the aforementioned double anti-counterfeiting inner cap is a large lead four-thread thread, and the aforementioned internal thread is rotatably adapted to the aforementioned external thread of the bottle opening.

[0010] This design allows the bottle cap to be opened simply by rotating the assembly of the outer cap and the double anti-counterfeiting inner cap counterclockwise by 90°. This significantly reduces the rotation stroke and time required for opening, avoiding the cumbersome operation of traditional threaded bottle caps that require multiple rotations. This greatly improves the convenience and user experience for consumers when opening the bottle cap. At the same time, while ensuring the quick opening function, the threaded connection still ensures the connection stability and sealing of the bottle cap during assembly.

[0011] Optionally: The aforementioned folded skirt is located at the lower part of the aforementioned double anti-counterfeiting inner cap. When the bottle cap is pressed onto the aforementioned bottle mouth, the aforementioned folded skirt folds over and is engaged with the aforementioned edge of the aforementioned bottle mouth.

[0012] This design allows the cap to be secured and prevented from loosening by engaging with the folded skirt and the edge of the bottle opening, thus improving sealing performance. It also works in conjunction with the anti-theft ring to form double physical protection, enhancing anti-counterfeiting measures and preventing the cap from being illegally reused.

[0013] Optionally, the sealing cylindrical surface is tightly fitted to the sealing surface of the bottle opening.

[0014] With this configuration, when the bottle cap is in place, the aforementioned sealing cylindrical surface and the aforementioned sealing surface come into close contact to achieve a seal, effectively blocking the bottle opening and preventing foreign objects from entering the bottle opening or liquid from overflowing from the bottle opening.

[0015] Optionally: the retaining ring of the outer cover is an annular protrusion structure, and the annular groove of the double anti-counterfeiting inner cover is an annular groove structure. The retaining ring and the annular groove are interlocked and interference-fitted.

[0016] This design allows for quick assembly of the outer cover and the double anti-counterfeiting inner cover, while ensuring a secure connection between the two to prevent loosening after assembly. It also simplifies the component connection structure and reduces assembly complexity.

[0017] Optionally, multiple of the aforementioned protruding strips and anti-rotation ribs are provided and are evenly distributed along the circumference, with each of the aforementioned protruding strips and anti-rotation ribs corresponding to one another.

[0018] This design, through the precise cooperation of multiple sets of circumferentially evenly distributed convex strips and anti-rotation ribs, ensures that the outer cover and the double anti-counterfeiting inner cover rotate synchronously, avoiding relative slippage, while evenly distributing the force and improving the structural stability after assembly.

[0019] Optionally: The aforementioned transparent gasket is made of PP material, and the inner code is set on the inner side of the inner surface of the aforementioned top plate.

[0020] With this design, the transparent gasket made of PP material has both good transparency and stability, and can clearly expose the inner code on the inner surface of the top plate, which facilitates the identification of the inner code and the association of the outer code data, thus realizing digital traceability.

[0021] Optionally, the connection points mentioned above are fragile connection structures spaced apart along the circumference of the ring body, and break along the connection points when subjected to force.

[0022] With this design, the fragile connection points with circumferential spacing can be precisely broken under force when opened, ensuring that the anti-theft ring and the double anti-counterfeiting inner cap are completely separated and cannot be restored, effectively achieving one-time anti-counterfeiting and preventing the bottle cap from being illegally recycled and reused.

[0023] Optionally, the bottom end of the outer cover has a limiting end, which abuts against the limiting step.

[0024] With this configuration, the assembly positions of the outer cover and the double anti-counterfeiting inner cover are precisely defined by the limiting end and the limiting step, avoiding excessive fitting of the outer cover and ensuring the axial structural stability of the two after assembly, thus preventing relative movement.

[0025] Optionally, the sealing cylindrical surface is the annular smooth surface of the inner wall of the double anti-counterfeiting inner cap, and the diameter of the sealing cylindrical surface is adapted to the diameter of the sealing surface of the bottle mouth, and the sealing cylindrical surface and the sealing surface are mutually interference-sealed.

[0026] With this configuration, the diameter of the sealing cylindrical surface of the annular smooth surface is matched and interference fits the diameter of the sealing surface of the bottle mouth, which can form an effective seal by tightly fitting together, preventing the alcohol from evaporating and leaking. At the same time, the smooth surface reduces assembly wear and ensures stable and long-lasting sealing performance.

[0027] In summary, the two-piece anti-counterfeiting wine cap disclosed in this utility model has the beneficial effects of reducing the number of parts, improving production efficiency, and reducing production costs while ensuring functionality. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0032] 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.

[0033] Example See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 This embodiment proposes a two-piece anti-counterfeiting wine cap, including an outer cap 1 and a double anti-counterfeiting inner cap 2; The outer cover 1 is assembled downwards and fastened to the upper end of the double anti-counterfeiting inner cover 2. The assembly of the outer cover 1 and the double anti-counterfeiting inner cover 2 is press-fitted onto the bottle mouth 6, which has external threads 3, a flange 4 and a sealing surface 5. The outer cover 1 is provided with a cavity 7, a protrusion 8 and a retaining ring 9. The cavity 7 is fitted on the upper part of the double anti-counterfeiting inner cover 2, and the protrusion 8 is arranged axially along the inner wall of the cavity 7. The double anti-counterfeiting inner cover 2 is provided with anti-rotation rib 10, annular groove 11, limiting step 12, internal thread 13, folded skirt 14, sealing cylindrical surface 15, anti-theft ring 16, transparent gasket 17 and top plate inner surface 18. The anti-rotation rib 10 and the protruding strip 8 are mutually adapted to prevent rotation, the annular groove 11 is adapted to the snap ring 9 to fasten, and the bottom end of the outer cover 1 abuts against the limiting step 12. The anti-theft ring 16 has a connection point 19 and a ring body 20. The connection point 19 is used to connect the ring body 20 to the main body of the double anti-counterfeiting inner cover 2. When opened, the connection point 19 can break, causing the ring body 20 to separate and become irreparable. The transparent gasket 17 is injection molded in two colors inside the double anti-counterfeiting inner cover 2. The inner surface 18 of the top plate has an inner code (not shown in the figure), and the inner code is data-linked with the outer code on the top of the outer cover 1.

[0034] During assembly, the outer cap 1 is first aligned and fitted onto the upper end of the double anti-counterfeiting inner cap 2, so that the upper structure of the double anti-counterfeiting inner cap 2 gradually enters the cavity 7 of the outer cap 1. During the process, the protrusion 8 on the inner wall of the cavity 7 corresponds and matches the anti-rotation rib 10 of the double anti-counterfeiting inner cap 2. After the retaining ring 9 of the outer cap 1 is elastically deformed, it is embedded in the annular groove 11 of the double anti-counterfeiting inner cap 2 until the bottom end of the outer cap 1 abuts against the limiting step 12 of the double anti-counterfeiting inner cap 2, thus completing the snap-fit ​​and fixing of the outer cap 1 and the double anti-counterfeiting inner cap 2, forming a two-piece anti-counterfeiting wine cap assembly. The assembly is then aligned with the bottle neck 6 and pressed downwards. The assembly is pressed downwards gradually until the sealing cylindrical surface 15 of the double anti-counterfeiting inner cap 2 is tightly fitted with the sealing surface 5 of the bottle neck 6. At the same time, the folded skirt 14 of the double anti-counterfeiting inner cap 2 is squeezed and folded by the platform edge 4 of the bottle neck 6 and snapped onto the platform edge 4. The internal thread 13 of the double anti-counterfeiting inner cap 2 engages with the external thread 3 of the bottle neck 6, completing the assembly of the cap and the bottle neck 6.

[0035] This embodiment discloses a two-piece anti-counterfeiting bottle cap. Due to its streamlined two-piece structure of an outer cap 1 and a double anti-counterfeiting inner cap 2, compared to traditional multi-part bottle caps, it significantly reduces the number of parts, simplifies the assembly process, and lowers production and assembly costs. Simultaneously, the outer cap 1 is responsible for appearance decoration and brand display, while the double anti-counterfeiting inner cap 2 integrates sealing, physical anti-counterfeiting, and digital traceability functions, achieving clear and comprehensive functional division. Specifically, when the bottle cap does not require brand display, the decorative outer cap 1 is unnecessary; the double anti-counterfeiting inner cap 2 alone can achieve sealing, connection, and physical information anti-counterfeiting. Furthermore, the large-lead four-thread design of the double anti-counterfeiting inner cap 2, combined with the anti-rotation cooperation of the outer cap 1 and the double anti-counterfeiting inner cap 2, The design allows for easy opening with a simple 90° counter-rotation, enhancing the user experience. The interlocking of the folded skirt 14 with the edge 4 of the bottle mouth 6, and the interference fit between the sealing cylinder 15 and the sealing surface 5 of the bottle mouth 6, provide double protection for sealing performance and assembly stability. The fragile connection point 19 of the anti-theft ring 16 prevents it from being restored after opening, achieving physical anti-counterfeiting. The dual-color injection-molded transparent gasket 17, combined with the data association between the inner code and the outer code of the outer cap 1, further enables digital traceability. This comprehensively meets the core needs of wine bottle caps for cost, safety, branding, and digitalization, resulting in a two-piece anti-counterfeiting wine cap that, while maintaining functionality, reduces the number of parts, improves production efficiency, and lowers production costs.

[0036] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The inner thread 13 of the double anti-counterfeiting inner cap 2 is a large lead four-thread thread. After the assembly is pressed into place, the inner thread 13 is adapted to the outer thread 3 of the bottle mouth 6. This allows the bottle cap to be opened by simply rotating the assembly of the outer cap 1 and the double anti-counterfeiting inner cap 2 counterclockwise by 90°. This significantly shortens the rotation stroke and time required for opening, avoiding the cumbersome operation of traditional threaded bottle caps that require multiple rotations. This significantly improves the convenience and user experience of opening the bottle cap for consumers. At the same time, while ensuring the quick opening function, the connection stability and sealing of the bottle cap during assembly can still be ensured by the thread fit.

[0037] The folded skirt 14 is located at the lower part of the double anti-counterfeiting inner cap 2. When the cap is pressed into the bottle mouth 6, the folded skirt 14 folds over and is locked onto the edge 4 of the bottle mouth 6. This not only locks the cap in place and prevents it from loosening by locking the folded skirt 14 onto the edge 4 of the bottle mouth 6, thus improving the sealing performance, but also works with the anti-theft ring 16 to form double physical protection, enhance the anti-counterfeiting effect, and prevent the cap from being illegally reused.

[0038] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The sealing cylindrical surface 15 is tightly fitted to the sealing surface 5 of the bottle mouth 6. When the bottle cap is installed in place, the sealing cylindrical surface 15 and the sealing surface 5 are in close contact to achieve a seal, effectively blocking the bottle mouth 6 and preventing foreign objects from entering the bottle mouth 6 or liquid from overflowing from the bottle mouth 6.

[0039] The retaining ring 9 of the outer cover 1 is a ring-shaped protrusion structure, and the ring groove 11 of the double anti-counterfeiting inner cover 2 is a ring-shaped groove structure. The retaining ring 9 and the ring groove 11 are interlocked and interference-fitted. This can quickly complete the assembly of the outer cover 1 and the double anti-counterfeiting inner cover 2, and ensure that the connection between the two is stable, preventing loosening after assembly. At the same time, it simplifies the component connection structure and reduces the assembly complexity.

[0040] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 Multiple convex strips 8 and anti-rotation ribs 10 are provided and are evenly distributed along the circumference. Multiple convex strips 8 and multiple anti-rotation ribs 10 are matched one-to-one. Through the precise matching of multiple sets of evenly distributed circumferential convex strips 8 and anti-rotation ribs 10, the outer cover 1 and the double anti-counterfeiting inner cover 2 are ensured to rotate synchronously, avoiding relative slippage. At the same time, the force is evenly distributed, improving the structural stability of the two after assembly.

[0041] The transparent gasket 17 is made of PP material, and the inner code is set on the inner side of the inner surface 18 of the top plate. The transparent gasket 17 made of PP material has both good transparency and stability, and can clearly expose the inner code of the inner surface 18 of the top plate, which is convenient for the identification of the inner code and the association of the outer code data, so as to realize digital traceability.

[0042] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 Connection point 19 is a fragile connection structure that is spaced out circumferentially along the ring body 20. When subjected to force, it breaks at connection point 19. The circumferentially spaced fragile connection points 19 can break precisely under force when opened, ensuring that the anti-theft ring 16 and the double anti-counterfeiting inner cap 2 are completely separated and cannot be restored, effectively achieving one-time anti-counterfeiting and preventing the bottle cap from being illegally recycled and reused.

[0043] The bottom end of the outer cover 1 has a limiting end 21, which abuts against the limiting step 12. By abutting against the limiting step 12, the assembly position of the outer cover 1 and the double anti-counterfeiting inner cover 2 is precisely limited, avoiding overfitting of the outer cover 1 and ensuring the axial structural stability of the two after assembly, preventing relative movement.

[0044] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The sealing cylinder 15 is an annular smooth surface on the inner wall of the double anti-counterfeiting inner cap 2, and the diameter of the sealing cylinder 15 is adapted to the diameter of the sealing surface 5 of the bottle mouth 6. The sealing cylinder 15 and the sealing surface 5 are interference-fitted to each other. The annular smooth surface of the sealing cylinder 15 and the sealing surface 5 of the bottle mouth 6 are adapted to each other and interference-fitted, which can fit tightly to form an effective seal, preventing the evaporation and leakage of alcohol. At the same time, the smooth surface reduces assembly wear and ensures stable and long-lasting sealing performance.

[0045] The cross-section of the protrusion 8 of the outer cover 1 is a trapezoidal structure, with the upper base of the trapezoid facing the center of the cavity 7 and the lower base connected to the inner wall of the cavity 7; the cross-section of the anti-rotation rib 10 of the double anti-counterfeiting inner cover 2 is a trapezoidal groove structure that matches the protrusion 8. After the protrusion 8 is embedded in the groove, it forms an anti-rotation fit. This design not only enhances the stability of the anti-rotation fit between the outer cover 1 and the double anti-counterfeiting inner cover 2 and avoids relative slippage, but also facilitates the rapid embedding of the protrusion 8 into the groove during assembly by guiding the trapezoidal structure, thereby improving assembly efficiency.

[0046] The outer wall of the outer cap 1 is provided with several anti-slip textures (not shown in the figure) along the axial direction. The anti-slip textures are arranged on the outer wall of the outer cap 1 along the circumference. The anti-slip textures can increase the friction between the user's hand and the outer cap 1, avoid slipping when opening or screwing on the wine cap, and improve the ease of operation. At the same time, the anti-slip texture structure is simple and does not affect the appearance integrity of the outer cap 1 or the brand display effect.

[0047] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 In this embodiment, the simplified two-piece structure meets the core requirements of cost, safety, brand, and digitalization for wine bottle cap packaging. The outer cap 1 achieves overall aesthetics and brand display, while the double anti-counterfeiting inner cap 2 is responsible for sealing, connection, and physical information anti-counterfeiting, realizing four major functions: appearance decoration, sealing function, mechanical anti-counterfeiting, and digital traceability. With only two components, the decorative outer cap 1 and the double anti-counterfeiting inner cap 2, the assembly is simple and the cost is low. In particular, when the wine cap does not require brand display, the decorative outer cap 1 is not needed, and the double anti-counterfeiting inner cap 2 alone can achieve sealing, connection, and physical information anti-counterfeiting.

[0048] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 In this embodiment, the simplified structural design allows the double anti-counterfeiting inner cap 2 to have enough space to design a large-lead four-threaded design. When opening, the cap can be opened by simply rotating it 90° in the opposite direction, which greatly enhances the consumer's experience.

[0049] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The specific working principle of the two-piece anti-counterfeiting cap in this embodiment: First, the outer cover 1 is fitted onto the upper end of the double anti-counterfeiting inner cover 2. The protrusion 8 on the inner wall of the cavity 7 of the outer cover 1 is adapted to the anti-rotation rib 10 of the double anti-counterfeiting inner cover 2 to prevent rotation. The retaining ring 9 is inserted into the annular groove 11 of the double anti-counterfeiting inner cover 2 to achieve fastening. The bottom end of the outer cover 1 abuts against the limiting step 12 of the double anti-counterfeiting inner cover 2 to complete the limiting, forming a two-piece assembly. Then, the assembly is pressed onto the bottle mouth 6. The internal thread 13 of the double anti-counterfeiting inner cover 2 engages with the external thread 3 of the bottle mouth 6 until the sealing column surface 15 is in contact with the sealing surface 5 of the bottle mouth 6 and seals. At the same time, the folded skirt 14 of the double anti-counterfeiting inner cover 2 is squeezed and folded by the platform edge 4 of the bottle mouth 6 to complete the fixed assembly with the bottle mouth 6. When opened, the assembly is rotated in reverse. Because the double anti-counterfeiting inner cap 2 has a large lead four-thread, it only needs to be rotated 90° to separate the double anti-counterfeiting inner cap 2 from the bottle mouth 6 thread. During the rotation, the weak connection point 19 of the anti-theft ring 16 of the double anti-counterfeiting inner cap 2 breaks under force, and the ring 20 separates from the inner cap body and cannot be restored. The non-restoreability of the ring 20 achieves physical anti-counterfeiting and prevents the bottle cap from being illegally recycled and reused. The transparent gasket 17 of the double anti-counterfeiting inner cover 2 is made of two-color injection molding, and the inner code on the inner surface 18 of the top plate can be clearly identified through the gasket. The inner code is pre-established with the outer code on the top of the outer cover 1. Consumers or regulators can retrieve the product information (such as production batch, traceability path, etc.) corresponding to the inner code by scanning the outer code, so as to realize the digital traceability of the product throughout the entire process and further ensure that the authenticity of the product can be verified.

[0050] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
