Description

Technical Field

[0001] This utility model relates to the field of anti-counterfeiting technology for bottle caps, and more specifically, to an anti-counterfeiting bottle cap. Background Technology

[0002] Currently, most large-diameter bottled wine bottles on the market that use bottle stoppers employ clamps to lock the caps in place. This results in limitations on the overall appearance of the cap and the bottle. The caps themselves lack anti-counterfeiting features, and to ensure a tight seal, the caps usually require considerable force to remove, leading to a poor opening experience. Furthermore, most bottled wine bottles that use bottle stoppers lack a flow control mechanism, making it difficult to control the flow rate when pouring wine, and wine tends to spill along the bottle opening, further complicating the user experience. Utility Model Content

[0003] The present invention aims to provide an anti-counterfeiting bottle cap to solve the problems of large-diameter wine bottles being restricted in appearance by clamps, lacking anti-counterfeiting features, difficult to open, difficult to control the flow of wine, and easy spillage in the prior art.

[0004] The embodiments of this utility model are implemented as follows: This utility model provides an anti-counterfeiting bottle cap, which includes an upper component, a lower component, and a bottle mouth; The upper component includes an outer cap, a connector, and a seal; the lower component includes a bottle nozzle and a locking mechanism. The outer cover is provided with a first protruding rib, a first buckle and an anti-counterfeiting ring, and the anti-counterfeiting ring is provided with a third buckle, a connection point and a twist-off ring; The aforementioned connector is provided with a second snap, a first edge, a limiting groove, an external thread, and a lower sealing cylindrical surface; The aforementioned seal is provided with a second flange and a sealing cylindrical surface; The above-mentioned bottle nozzle is equipped with a guide bevel, a groove, a backflow preventer, an anti-surge device, and a wine outlet; The aforementioned locking component includes a third flange, internal thread, pawl, sealing outer ring surface, anti-rotation protrusion, fourth flange, and sealing inner ring surface; The bottle opening is equipped with positioning teeth and a bottle opening sealing surface; The aforementioned sealing element and the aforementioned connecting element are engaged in a snap-fit ​​configuration. The aforementioned outer cover is assembled and fixed with the aforementioned connecting element and the aforementioned sealing element in a combination. The aforementioned bottle nozzle is assembled inside the aforementioned locking element. The aforementioned upper component and the aforementioned lower component are pre-fitted with threads. The aforementioned lower component is press-fitted with the aforementioned bottle opening in an interference seal configuration. The aforementioned anti-counterfeiting ring is engaged in a snap-fit ​​configuration with the locking element.

[0005] During assembly, first assemble the sealing element from the lower end of the connector upwards, so that the second edge of the sealing element engages with the second snap fastener of the connector; then assemble the outer cover from the upper end of the assembly of the connector and the sealing element downwards, so that the first rib of the outer cover engages with the limiting groove of the connector, and the first snap fastener engages with the first edge of the connector, thus completing the assembly of the upper component. Then, the bottle nipple is placed into the cavity of the locking member, so that the guide slope of the bottle nipple fits against the third edge upper slope of the locking member, and then the upper component and the lower component are pre-fitted through the external thread of the connector and the internal thread of the locking member. Finally, the pre-assembled whole is pressed onto the bottle mouth, so that the claws of the locking component retract into the bottle mouth, the outer sealing ring surface mates with the sealing surface of the bottle mouth, and the anti-rotation protrusion mates with the positioning teeth. It is further pressed onto the third edge of the locking component and engages with the groove of the bottle mouth, the lower sealing column surface of the connector seals with the inner sealing ring surface of the locking component, the anti-reverse ring of the bottle mouth abuts against the claws to lock the bottle mouth, and the third buckle of the anti-counterfeiting ring of the outer cap engages with the fourth edge of the locking component, thus completing the overall assembly.

[0006] The anti-counterfeiting bottle cap disclosed in this embodiment adopts a modular assembly structure of the upper component, the lower component, and the bottle mouth. The components are precisely connected and sealed through multi-dimensional cooperation such as snaps, threads, and beveled surfaces. This solves the limitations imposed on the bottle's appearance by traditional clamp locking and, through the twist-off design of the anti-counterfeiting ring, forms an irreversible physical anti-counterfeiting mark, effectively preventing secondary counterfeiting. Simultaneously, the anti-surge device of the bottle mouth and the protruding wine outlet, combined with the multi-position sealing of the sealing element, avoid the problems of uncontrollable flow and spillage along the bottle mouth during pouring, ensuring overall sealing performance and optimizing the opening experience. This comprehensively improves the shortcomings of traditional stopper-type wine bottles in terms of appearance, anti-counterfeiting, sealing, and user experience, resulting in an anti-counterfeiting bottle cap with the beneficial effects of good appearance, anti-counterfeiting function, effortless opening, easy flow control during pouring, and reduced spillage.

[0007] Optionally, the sealing element is assembled from the lower end of the connector upwards, and the second edge of the sealing element engages with the second snap-fit ​​of the connector.

[0008] This design allows for quick positioning and assembly of the sealing element and the connecting element using a snap-fit ​​mechanism, simplifying the assembly process, improving production efficiency, and avoiding the inconvenience caused by complex connection structures. In addition, the snap-fit ​​mechanism can form a stable connection, preventing the sealing element from shifting or falling off relative to the connecting element during subsequent bottle loading, opening, or use, ensuring the overall sealing effect of the bottle cap and preventing leakage of the wine.

[0009] Optionally: the outer cover is assembled downward from the upper end of the assembly of the connector and the seal, the first protrusion of the outer cover engages with the limiting groove of the connector, and the first buckle of the outer cover engages with the first edge of the connector.

[0010] This configuration restricts the circumferential rotation of the outer cover and the assembly by cooperating with the first protruding rib and the limiting groove, ensuring synchronous linkage when opening; the first buckle and the first mounting edge are engaged to achieve axial fixation, preventing the outer cover from loosening; and no additional fasteners are required, simplifying assembly, reducing costs, and ensuring the stability of the upper component structure, laying the foundation for subsequent cooperation and anti-counterfeiting functions.

[0011] Optionally: the bottle nozzle is placed into the cavity of the locking member, the guide slope of the bottle nozzle is in contact with the third edge upper slope of the locking member, and the upper component and the lower component are pre-fitted with the internal thread of the locking member through the external thread of the connector.

[0012] With this configuration, the guide slope and the third step along the upper slope can be fitted together to achieve precise pre-positioning of the bottle nozzle in the locking component, avoiding assembly misalignment; the pre-fitting of the external thread and the internal thread can quickly complete the initial connection of the upper and lower components, laying the foundation for subsequent press-fitting and locking when loading the bottle.

[0013] Optionally: when the lower component is assembled with the bottle opening, the claw of the locking member shrinks and deforms to fit into the bottle opening, the sealing outer ring surface fits tightly with the sealing surface of the bottle opening, and the anti-rotation protrusion cooperates with the positioning tooth to prevent rotation; After further pressing, the third edge of the above-mentioned device engages with the groove of the above-mentioned bottle mouth, the lower sealing column surface of the above-mentioned connector engages with the inner sealing ring surface of the above-mentioned locking member, the anti-reverse ring of the above-mentioned bottle mouth abuts against the claw of the above-mentioned locking member and deforms it outward to lock it with the sealing surface of the above-mentioned bottle mouth, and the third buckle of the above-mentioned outer cover engages with the fourth edge of the above-mentioned locking member.

[0014] With this configuration, when the lower component is assembled with the bottle neck, the retracting and insertion of the claws, the fitting of the outer sealing ring, and the engagement of the anti-rotation protrusion with the positioning teeth quickly complete the initial positioning, sealing, and anti-rotation, ensuring the stability of the assembly base. After further pressing, the multi-structure collaboration of the third edge engaging with the groove and the lower sealing cylinder sealing with the inner sealing ring enhances the connection sealing performance. The anti-reverse ring abuts against the outward expansion of the claws to lock the bottle neck, improving the overall locking firmness. The engagement of the third buckle with the fourth edge secures the upper and lower components, ultimately achieving a reliable seal, anti-loosening, and anti-rotation between the bottle cap and the bottle neck, ensuring structural stability when unopened and preventing leakage of the wine.

[0015] Optionally: the outer cover drives the upper component to rotate, the engagement length of the external thread of the connector and the internal thread of the locking member decreases, the upper component separates from the lower component, the connection point of the anti-counterfeiting ring breaks, and the torsion ring separates from the outer cover.

[0016] With this configuration, the rotation of the upper component driven by the outer cover reduces the engagement length between the external and internal threads, enabling smooth separation of the upper and lower components and ensuring a smooth opening operation. At the same time, the breakage of the connection point and the separation of the torsion ring from the outer cover form an irreversible physical anti-counterfeiting mark, directly proving whether the bottle cap has been opened, effectively preventing counterfeiting through secondary use, and ensuring that the authenticity of the product can be identified.

[0017] Optionally, the outlet of the bottle nipple extends beyond the top of the locking member, and the anti-surge device is disposed inside the bottle nipple.

[0018] This design prevents the wine from dripping down the outer wall of the bottle opening when pouring, while the anti-flow device limits the pouring flow rate and prevents the wine from overflowing. Together, they improve the controllability and user experience of pouring wine, while also ensuring the cleanliness of the pouring process.

[0019] Optionally: The outer wall of the outer cover is provided with several evenly distributed anti-slip textures.

[0020] With this design, the anti-slip texture increases the friction between the hand and the outer wall of the cover, preventing the hand from slipping when opening and ensuring stable force to rotate the upper component, thus improving the convenience and reliability of the opening operation.

[0021] Optionally, the lower section of the aforementioned seal can be sealed and embedded into the wine outlet of the aforementioned bottle mouth.

[0022] This design further enhances the sealing performance of the outlet, effectively preventing external air from entering the bottle or the wine from leaking out of the outlet. At the same time, the embedded structure improves the connection stability between the seal and the bottle mouth, preventing the seal from shifting and affecting the sealing effect, and ensuring the overall sealing reliability of the bottle cap.

[0023] Optionally: the anti-counterfeiting ring of the outer cover is disposed at the lower end of the outer cover along the axial direction of the outer cover, the twisted ring is a ring structure and is connected to the anti-counterfeiting ring through at least two evenly distributed connection points, and the third buckle protrudes along the inner circumference of the twisted ring.

[0024] With this configuration, the anti-counterfeiting ring is axially positioned at the lower end of the outer cover to precisely engage with the locking component; the torsion ring is connected to the anti-counterfeiting ring through at least two evenly distributed connection points, balancing the connection strength when not opened and the reliable breakage when opened; the third buckle protrudes along the inner circumference of the torsion ring, which can stably engage the locking component, ensuring structural stability when not opened and not affecting the torsion separation.

[0025] Optionally, the limiting groove of the connector is a rectangular groove opened along the axial direction of the connector, and the number of rectangular grooves is the same as the number of the first ribs on the inner wall of the outer cover. The first ribs are protruding along the inner circumference of the outer cover and slide in a one-to-one correspondence with the limiting grooves.

[0026] With this configuration, the aforementioned limiting groove of the rectangular groove slides in conjunction with the corresponding number of the aforementioned first protrusions, which can not only precisely limit the circumferential relative rotation of the aforementioned outer cover and the aforementioned connector to ensure synchronous linkage when opening, but also improve the smoothness of assembly through the adapted sliding structure, and ensure the connection stability of the aforementioned upper components.

[0027] In summary, the anti-counterfeiting bottle cap disclosed in this utility model has the advantages of good appearance, anti-counterfeiting function, easy opening, easy control of pouring flow, and less leakage. Attached Figure Description

[0033] Example See Figures 1 to 11 An anti-counterfeiting bottle cap includes an upper component 1, a lower component 2, and a bottle mouth 3; The upper component 1 includes an outer cover 4, a connector 5, and a seal 6; the lower component 2 includes a bottle mouth 7 and a locking component 8. The outer cover 4 is provided with a first protruding rib 9, a first buckle 10 and an anti-counterfeiting ring 11. The anti-counterfeiting ring 11 is provided with a third buckle 12, a connection point 13 and a twist ring 14. The connector 5 is provided with a second buckle 15, a first edge 16, a limiting groove 17, an external thread 18, and a lower sealing cylindrical surface 2119; The seal 6 is provided with a second edge 20 and a sealing cylindrical surface 21; The bottle spout 7 is provided with a guide slope 22, a groove 23, a backflow preventer 24, an anti-surge device 25, and a wine outlet 26; The locking component 8 is provided with a third edge 27, an internal thread 28, a pawl 29, a sealing outer ring surface 30, an anti-rotation protrusion 31, a fourth edge 32, and a sealing inner ring surface 33; The bottle mouth 3 is provided with positioning teeth 34 and a sealing surface of the bottle mouth 3; The sealing element 6 and the connecting element 5 are snapped together. The outer cover 4 is assembled and fixed with the combination of the connecting element 5 and the sealing element 6. The bottle mouth 7 is assembled in the locking element 8. The upper component 1 and the lower component 2 are pre-fitted with threads. The lower component 2 and the bottle mouth 3 are press-fitted together. The anti-counterfeiting ring 11 is snapped together with the locking element 8.

[0034] During assembly, first assemble the seal 6 from the lower end of the connector 5 upwards, so that the second edge 20 of the seal 6 engages with the second snap 15 of the connector 5; then assemble the outer cover 4 from the upper end of the assembly of the connector 5 and the seal 6 downwards, so that the first rib 9 of the outer cover 4 engages with the limiting groove 17 of the connector 5 and the first snap 10 engages with the first edge 16 of the connector 5, thus completing the assembly of the upper component 1. Then, the bottle nipple 7 is placed into the cavity of the locking component 8, so that the guide slope 22 of the bottle nipple 7 fits against the upper slope of the third edge 27 of the locking component 8, and then the upper component 1 and the lower component 2 are pre-fitted through the external thread 18 of the connector 5 and the internal thread 28 of the locking component 8. Finally, the pre-assembled whole is pressed onto the bottle mouth 3, so that the claw 29 of the locking part 8 retracts into the bottle mouth 3, the sealing outer ring surface 30 mates with the sealing surface of the bottle mouth 3, the anti-rotation protrusion 31 mates with the positioning tooth 34, and is further pressed onto the third edge 27 of the locking part 8 and the slot 23 of the bottle mouth 7, the lower sealing column surface 2119 of the connecting part 5 seals with the sealing inner ring surface 33 of the locking part 8, the anti-reverse ring 24 of the bottle mouth 7 abuts against the claw 29 to lock the bottle mouth 3, and the third buckle 12 of the anti-counterfeiting ring 11 of the outer cover 4 engages with the fourth edge 32 of the locking part 8, thus completing the overall assembly.

[0035] The anti-counterfeiting bottle cap disclosed in this implementation scheme adopts a modular assembly structure of upper component 1, lower component 2, and bottle mouth 3. The components are precisely connected and sealed through multi-dimensional cooperation such as buckles, threads, and beveled fits. This not only solves the limitation of traditional clamp locking on the appearance of the bottle, but also forms an irreversible physical anti-counterfeiting mark through the twist-off design of the anti-counterfeiting ring 11, effectively preventing secondary counterfeiting. At the same time, the anti-surge device 25 of the bottle mouth 7 and the protruding wine outlet 26, together with the multi-position sealing cooperation of the sealing element 6, not only avoid the problem of difficult flow control and wine spillage along the bottle mouth 3 when pouring wine, but also ensure the overall sealing performance and optimize the opening operation experience. It comprehensively improves the shortcomings of traditional bottle stopper-type wine bottles in terms of appearance, anti-counterfeiting, sealing, and user experience. Thus, an anti-counterfeiting bottle cap has the beneficial effects of good appearance, anti-counterfeiting function, easy opening, easy flow control, and less wine spillage.

[0036] See Figures 1 to 11 The sealing element 6 is assembled from the lower end of the connector 5 upwards. The second edge 20 of the sealing element 6 engages with the second snap 15 of the connector 5. This snap engagement enables quick positioning and assembly of the sealing element 6 and the connector 5, simplifying the assembly process, improving production efficiency, and avoiding the inconvenience caused by complex connection structures. In addition, the snap engagement forms a stable connection, preventing the sealing element 6 from shifting or falling off relative to the connector 5 during subsequent bottle loading, opening, or use, ensuring the overall sealing effect of the bottle cap and preventing leakage of the wine.

[0037] The outer cover 4 is assembled downwards from the upper end of the assembly of connector 5 and seal 6. The first protruding rib 9 of the outer cover 4 cooperates with the limiting groove 17 of connector 5, and the first buckle 10 of the outer cover 4 engages with the first edge 16 of connector 5. The circumferential rotation of the outer cover 4 and the assembly is restricted by the cooperation of the first protruding rib 9 and the limiting groove 17, ensuring synchronous linkage when opening. The engagement of the first buckle 10 and the first edge 16 achieves axial fixation to prevent the outer cover 4 from loosening. Moreover, no additional fasteners are required, simplifying assembly, reducing costs, and ensuring the structural stability of the upper component 1, laying the foundation for subsequent cooperation and anti-counterfeiting functions.

[0038] See Figures 1 to 11 The bottle nozzle 7 is placed into the cavity of the locking component 8. The guide slope 22 of the bottle nozzle 7 is in contact with the upper slope of the third edge 27 of the locking component 8. The upper component 1 and the lower component 2 are pre-fitted with the internal thread 28 of the locking component 8 through the external thread 18 of the connector 5. The contact between the guide slope 22 and the upper slope of the third edge 27 can achieve precise pre-positioning of the bottle nozzle 7 in the locking component 8 and avoid assembly misalignment. The pre-fitting of the external thread 18 and the internal thread 28 can quickly complete the initial connection of the upper and lower components 2, laying the foundation for the subsequent press-fit locking when loading the bottle.

[0039] When the lower component 2 is assembled with the bottle mouth 3, the claw 29 of the locking member 8 shrinks and deforms to fit into the bottle mouth 3, the sealing outer ring surface 30 fits tightly with the sealing surface of the bottle mouth 3, and the anti-rotation protrusion 31 cooperates with the positioning tooth 34 to prevent rotation; after further pressing, the third edge 27 engages with the slot 23 of the bottle mouth 7, the lower sealing column surface 2119 of the connecting member 5 engages with the sealing inner ring surface 33 of the locking member 8, the anti-reverse ring 24 of the bottle mouth 7 abuts against the claw 29 of the locking member 8 and deforms it outward to lock it with the sealing surface of the bottle mouth 3, the third buckle 12 of the outer cover 4 engages with the fourth edge 32 of the locking member 8, and when the lower component 2 is assembled with the bottle mouth 3, the claw 29 shrinks and deforms to fit into the bottle mouth 3, the outer cover 4 engages with the fourth edge 32 of the locking member 8, and the claw 29 engages with the bottle mouth 3. The shrinkage insertion, sealing of the outer ring surface 30, and anti-rotation protrusion 31 and positioning teeth 34 can quickly complete the initial positioning, sealing, and anti-rotation, ensuring the stability of the assembly base. After further pressing, the multi-structure collaboration of the third edge 27 and the slot 23, and the sealing of the lower sealing column surface 2119 and the sealing inner ring surface 33, enhances the connection sealing performance. The anti-reverse ring 24 abuts against the claw 29 to expand and lock the bottle mouth 3, improving the overall locking firmness. The third buckle 12 and the fourth edge 32 engage to stabilize the upper component 1 and the lower component 2, ultimately achieving reliable sealing, anti-loosening, and anti-rotation of the bottle cap and bottle mouth 3, ensuring structural stability when not opened and preventing wine leakage.

[0040] See Figures 1 to 11 The outer cap 4 drives the upper component 1 to rotate, reducing the mating length between the external thread 18 of the connector 5 and the internal thread 28 of the locking component 8. This causes the upper component 1 to separate from the lower component 2, breaking the connection point 13 of the anti-counterfeiting ring 11 and separating the torsion ring 14 from the outer cap 4. By driving the upper component 1 to rotate through the outer cap 4, the mating length between the external thread 18 and the internal thread 28 is reduced, enabling the smooth separation of the upper and lower components 2 and ensuring smooth opening operation. At the same time, the breaking of the connection point 13 and the separation of the torsion ring 14 from the outer cap 4 form an irreversible physical anti-counterfeiting mark, directly proving whether the bottle cap has been opened, effectively preventing counterfeiting through secondary use, and ensuring that the authenticity of the product can be identified.

[0041] The outlet 26 of the bottle spout 7 extends out of the top of the locking member 8. The anti-surge device 25 is set inside the bottle spout 7. This can prevent the wine from flowing down the outer wall of the bottle mouth 3 when pouring. The anti-surge device 25 can limit the pouring speed and prevent the wine from overflowing. The two work together to improve the controllability and user experience of pouring wine, while ensuring the cleanliness of the pouring process.

[0042] See Figures 1 to 11 The outer wall of the outer cover 4 is provided with several evenly distributed anti-slip textures. The anti-slip textures can increase the friction between the hand and the outer wall of the outer cover 4, prevent the hand from slipping when opening, ensure that the upper component 1 can be rotated stably, and improve the convenience and reliability of the opening operation.

[0043] The lower section of the seal 6 can be embedded in the wine outlet 26 of the bottle mouth 7, which further enhances the sealing performance at the wine outlet 26, effectively preventing external air from entering the bottle or the wine in the bottle from leaking out of the wine outlet 26. At the same time, the embedded structure can improve the connection stability between the seal 6 and the bottle mouth 7, prevent the seal 6 from shifting and affecting the sealing effect, and ensure the overall sealing reliability of the bottle cap.

[0044] See Figures 1 to 11 The anti-counterfeiting ring 11 of the outer cover 4 is set at the lower end of the outer cover 4 along the axial direction of the outer cover 4. The twist-off ring 14 is a ring structure and is connected to the anti-counterfeiting ring 11 through at least two evenly distributed connection points 13. The third buckle 12 protrudes along the inner circumference of the twist-off ring 14. The anti-counterfeiting ring 11 is set at the lower end of the outer cover 4 along the axial direction to accurately engage with the locking element 8. The twist-off ring 14 is connected to the anti-counterfeiting ring 11 through at least two evenly distributed connection points 13, which takes into account both the connection strength when not opened and the reliable breakage when opened. The third buckle 12 protrudes along the inner circumference of the twist-off ring 14, which can stably engage with the locking element 8, ensuring that the structure is stable when not opened and does not affect the twist-off separation.

[0045] The limiting groove 17 of the connector 5 is a rectangular groove opened along the axial direction of the connector 5, and the number of rectangular grooves is the same as the number of first protruding ribs 9 on the inner wall of the outer cover 4. The first protruding ribs 9 are protruding along the inner circumference of the outer cover 4 and slide in a one-to-one correspondence with the limiting groove 17. The limiting groove 17 of the rectangular groove slides in a one-to-one correspondence with the corresponding number of first protruding ribs 9, which can not only accurately limit the relative circumferential rotation of the outer cover 4 and the connector 5 to ensure synchronous linkage when opening, but also improve the smoothness of assembly through the adapted sliding structure and ensure the connection stability of the upper component 1.

[0046] See Figures 1 to 11 In this embodiment, the outer cover 4, connector 5, seal 6, bottle mouth 7, locking member 8, and bottle mouth 3 are connected and fitted along the same axis.

[0047] See Figures 1 to 11 The anti-counterfeiting bottle cap principle in this embodiment is as follows: The bottle cap is disassembled into an upper component 1 (outer cap 4, connector 5, seal 6) and a lower component 2 (bottle mouth 7, locking component 8). During assembly, the upper component 1 is first assembled by snap-fitting (the second edge 20 of the seal 6 and the second snap 15 of the connector 5, and the first snap 10 of the outer cap 4 and the first edge 16 of the connector 5). Then, the lower component 2 is pre-positioned by the guide slope 22 of the bottle mouth 7 and the slope 27 of the third edge 27 of the locking component 8. Finally, the external thread 18 of the upper component 1 and the internal thread 28 of the lower component 2 are pre-fitted, laying the foundation for the subsequent precise assembly with the bottle mouth 3.

[0048] When the lower component 2 is assembled with the bottle mouth 3, the claw 29 of the locking component 8 first shrinks and deforms to enter the bottle mouth 3. At the same time, the sealing outer ring surface 30 initially fits with the sealing surface of the bottle mouth 3, and the anti-rotation protrusion 31 cooperates with the positioning tooth 34 to prevent rotation. After further pressing, the anti-reverse ring 24 of the bottle mouth 7 abuts against the claw 29 to deform it outward and tightly locks it with the sealing surface of the bottle mouth 3. At the same time, the lower sealing column surface 2119 of the connecting component 5 and the sealing inner ring surface 33 of the locking component 8, and the sealing component 6 and the wine outlet 26 of the bottle mouth 7 form multiple seals, which not only ensures the structural stability but also prevents the wine from leaking.

[0049] When not in use, the third buckle 12 of the anti-counterfeiting ring 11 on the outer cap 4 engages with the fourth edge 32 of the locking component 8, ensuring a stable connection between the upper and lower components 2. When opened, rotating the outer cap 4 causes the upper component 1 to rotate, reducing the engagement length between the external thread 18 of the upper component 1 and the internal thread 28 of the lower component 2. This forces the connection point 13 of the anti-counterfeiting ring 11 to break, causing the twisted ring 14 to separate from the outer cap 4, forming an irreversible physical damage mark that directly proves that the bottle cap has been opened, thus preventing secondary counterfeiting.

[0050] The wine outlet 26 of the bottle spout 7 extends from the top of the locking piece 8, which can prevent the wine from flowing down the outer wall of the bottle mouth 3 when pouring; at the same time, the anti-flow device 25 inside the bottle spout 7 can prevent the wine from flowing out quickly, limit the pouring speed, achieve controllable flow, and improve the pouring experience.
