Description

Technical Field

[0001] This utility model relates to the field of anti-counterfeiting technology for wine bottle caps, and in particular to a double anti-counterfeiting threaded wine bottle cap. Background Technology

[0002] Bottle caps are structural components used to seal the mouth of wine bottles, serving functions such as leak prevention, preservation, dust prevention, and anti-counterfeiting. Depending on the type of wine, common bottle caps include metal screw caps, corks, plastic caps, and composite material caps. They are usually connected to the bottle neck by screwing, pressing, or inserting, making them easy to open while effectively preventing the evaporation of the wine and external contamination. Some bottle caps also integrate anti-counterfeiting structures to prevent resealing after opening, ensuring the authenticity and quality safety of the product.

[0003] Existing technologies for anti-counterfeiting features of bottle caps are limited. For example, they may use a break ring, tear strip, or one-time locking structure to provide a visual indication of the first opening. However, these anti-counterfeiting methods have significant limitations. These structures are mostly one-time designs and only provide anti-counterfeiting features when the bottle cap is opened for the first time. If the bottle cap is replaced or resealed, it is difficult to identify the counterfeit. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that the anti-counterfeiting function of bottle caps in the prior art is singular. For example, visual prompts for the first opening are achieved through a fracture ring, tear strip, or one-time locking structure. However, these anti-counterfeiting methods have obvious limitations. These structures are mostly one-time designs, providing anti-counterfeiting marks only when the bottle cap is opened for the first time. If the bottle cap is replaced or resealed, it is difficult to effectively identify the counterfeit. Therefore, a double anti-counterfeiting threaded bottle cap is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A double anti-counterfeiting threaded bottle cap includes a starting tube, a middle tube, and an ending tube. The ending tube is movably inserted into the bottle neck. One end of the ending tube is provided with a convex platform. The inner cavity of the ending tube is interference-fitted with the bottle neck.

[0007] The starting cylinder is fixedly provided with a closed cap at one end, the end cylinder is provided with a positioning shoulder on its outer wall, the middle cylinder is movably inserted into the outer wall of the positioning shoulder, and the end of the middle cylinder is provided with a docking component, which is used for quick insertion and fixing between the middle cylinder and the end cylinder.

[0008] The intermediate cylinder is a stepped cylinder composed of small-diameter cylindrical sections and large-diameter cylindrical sections connected in sequence, and the outer wall of the intermediate cylinder is provided with a double anti-counterfeiting component.

[0009] Optionally, the docking assembly includes inner locking teeth, a raised ring, and a receiving groove. The end of the end cylinder is fixedly provided with a raised ring, and one end of the intermediate cylinder has a circular array of inner locking teeth.

[0010] Optionally, the ends of the plurality of inner locking teeth away from the outer wall of the intermediate cylinder are inclined toward the central axis of the intermediate cylinder, and the end cylinder is provided with a receiving groove on the outer wall of one side of the protruding ring.

[0011] Optionally, the dual anti-counterfeiting component includes an anti-counterfeiting block, a first indicator block, and a second indicator block. An anti-counterfeiting block is fixedly provided on the side of the large-diameter cylindrical section of the intermediate cylinder. The anti-counterfeiting block is provided with a hollow groove in the middle position. A docking groove is provided on the edge of the side wall of the starting cylinder away from the closed cover. The anti-counterfeiting block is inserted into the docking groove.

[0012] Optionally, the outer wall of the small-diameter cylindrical section of the intermediate cylinder is provided with external threads, and the top of the first indicator block and the second indicator block are provided with inclined arc surfaces. The first indicator block and the second indicator block are sequentially fixed in the thread gap between adjacent threads of the external threads.

[0013] Optionally, the inner cavity of one end of the starting cylinder is provided with an internal thread, and a concentric tapered column is fixedly provided in the inner cavity of the starting cylinder.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] 1. This utility model bottle cap achieves visually identifiable dual anti-counterfeiting functions through two structures. The first layer of visual anti-counterfeiting is achieved through a breakable mechanism when the cap is unopened (the breakable part appears intact and undamaged; after opening, the integrity of the breakable part is compromised, resulting in permanent physical damage). The second layer of visual anti-counterfeiting is achieved by using an anti-counterfeiting slider on the threaded part of the cap after opening, preventing it from rotating completely and creating a certain spatial distance compared to when it is unopened. This allows for clear visual identification of any abnormalities in the cap. In summary, this utility model bottle cap achieves visually identifiable dual anti-counterfeiting functions through these two anti-counterfeiting technologies, meeting the high anti-counterfeiting requirements of the product at a low cost, thus improving the product's anti-counterfeiting function and cost-effectiveness.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-5 A double anti-counterfeiting threaded bottle cap includes a starting cylinder 3, a middle cylinder 9, and an end cylinder 5. The end cylinder 5 is movably inserted into the bottle neck. One end of the end cylinder 5 is provided with a convex platform 1. The inner cavity of the end cylinder 5 is interference-fitted with the bottle neck. One end of the starting cylinder 3 is fixedly provided with a sealing cap 2. The outer wall of the end cylinder 5 is provided with a positioning shoulder 51. The middle cylinder 9 is movably inserted into the outer wall of the positioning shoulder 51. The end of the middle cylinder 9 is provided with a docking component, which is used for quick insertion and fixing between the middle cylinder 9 and the end cylinder 5.

[0024] The docking assembly includes inner locking teeth 6, a raised ring 10, and a receiving groove 52. The raised ring 10 is fixedly provided at the end of the end cylinder 5. The middle cylinder 9 has a circular array of inner locking teeth 6 at one end. The ends of the multiple inner locking teeth 6 away from the outer wall of the middle cylinder 9 are inclined towards the central axis of the middle cylinder 9. The receiving groove 52 is provided on the outer wall of the side of the raised ring 10 of the end cylinder 5. When the middle cylinder 9 is inserted into the outer wall of the end cylinder 5, the raised ring 10 can force the multiple inner locking teeth 6 to expand and then enter the receiving groove 52, thus achieving relative fixation between the middle cylinder 9 and the end cylinder 5.

[0025] The positioning shoulder 51 is used so that when the intermediate cylinder 9 is inserted into the end cylinder 5, the intermediate cylinder 9 will not rotate around the end cylinder 5 when subjected to external force, so that the intermediate cylinder 9 can be connected to the starting cylinder 3 through the external thread 7 and the internal thread 32. The intermediate cylinder 9 is a stepped cylinder body composed of small diameter cylindrical sections and large diameter cylindrical sections connected in sequence. The outer wall of the intermediate cylinder 9 is provided with a double anti-counterfeiting component, which includes an anti-counterfeiting block 8, a first indicator block 71, and a second indicator block 72. The anti-counterfeiting block 8 is fixedly provided on the side of the large diameter cylindrical section of the intermediate cylinder 9. The middle position of the anti-counterfeiting block 8 is set as a hollow groove. The word "open" can also be set above the hollow groove of the anti-counterfeiting block 8. A docking groove 31 is provided on the edge of the side wall of the starting cylinder 3 away from the closing cover 2. The anti-counterfeiting block 8 is inserted into the docking groove 31.

[0026] The outer wall of the small-diameter cylindrical section of the intermediate cylinder 9 is provided with external threads 7. The top of the first indicator block 71 and the second indicator block 72 are provided with inclined arc surfaces. The first indicator block 71 and the second indicator block 72 are fixedly installed in the thread gap between adjacent threads of the external threads 7. The inner cavity of one end of the starting cylinder 3 is provided with internal threads 32. A concentric tapered column 4 is fixedly installed in the inner cavity of the starting cylinder 3. The tapered column 4 is made of soft rubber and is used to seal the inner cavity of the end cylinder 5.

[0027] The specific implementation steps and principles of this utility model are as follows:

[0028] When the bottle cap is in the closed state, the anti-counterfeiting block 8 is inserted into the docking groove 31. The starting cylinder 3 is connected to the intermediate cylinder 9 through the internal thread 32 and the external thread 7. When the bottle cap is opened, the user rotates the starting cylinder 3. The starting cylinder 3 rotates relative to the intermediate cylinder 9 and breaks the anti-counterfeiting block 8 through the docking groove 31. The threads of the internal thread 32 continuously separate from the external thread 7. Since the top of the first indicator block 71 is an inclined arc surface, the internal thread 32 can pass over the first indicator block 71. When the user screws the starting cylinder 3 with the closed cap 2 into a section of the intermediate cylinder 9 through the internal thread 32 and the external thread 7, the threads of the internal thread 32 will be blocked by the first indicator block 71, causing the starting cylinder 3 to not be completely screwed into one end of the intermediate cylinder 9. There is a certain gap between one end of the starting cylinder 3 and one end of the intermediate cylinder 9, indicating that the bottle cap has been opened.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
