Abstract
Description
Technical Field
[0001] The utility model relates to the field of wine bottle caps, in particular to an anti-counterfeiting bottle cap and a bottle with the bottle cap. Background Art
[0002] In the liquor industry, to prevent the resale of counterfeit liquor, major manufacturers incorporate special anti-counterfeiting features into their bottle caps. For example, bottle caps are typically welded using a welding ring or connected by hooking the outer and inner caps. However, welding presents numerous issues. For example, the welding process can easily cause deformation of the inner cap, affecting the overall seal and aesthetics of the cap. Furthermore, welded caps exhibit high torque, making them difficult to open and inconvenient for consumers. Hooking the outer and inner caps together can easily cause the hooks to become detached during use, resulting in poor anti-counterfeiting effectiveness and ineffective protection of product quality and brand image. Utility Model Content
[0003] In order to solve the technical problem that the inner cover and the outer cover of the existing bottle cap are easily separated, the utility model provides an anti-counterfeiting bottle cap and a bottle with the bottle cap.
[0004] The utility model is implemented using the following technical solution: an anti-counterfeit bottle cap comprising an outer cap, an inner cap, and a reverse gear structure. The inner cap is threadably mounted within the outer cap, and the reverse gear structure is used to prevent the outer cap and inner cap from being unlocked by reverse threading. The reverse gear structure includes a gear that is coaxially fixed to the outer wall of the inner cap and mounted on the inner wall of the outer cap, and at least one protrusion that is fixed to the inner wall of the outer cap and meshes with the gear. The teeth on the gear are all reverse gears, and the reverse gear prevents the protrusion from reversely rotating in the direction of the threads of the outer cap and inner cap being twisted to open the cap.
[0005] As a further improvement of the above solution, the gear is integrally formed on the outer wall of the inner cover.
[0006] As a further improvement of the above solution, the protrusion is integrally formed on the inner wall of the outer cover.
[0007] As a further improvement of the above solution, the protrusion is in a strip shape.
[0008] As a further improvement of the above solution, the strip-shaped protrusion is parallel to the axis of the gear.
[0009] As a further improvement of the above solution, the threads of the outer cover and the inner cover are located on the side of the reverse tooth structure facing the opening of the anti-counterfeit bottle cap.
[0010] As a further improvement of the above solution, there are multiple protrusions, and they are evenly distributed in a ring shape with the axis of the gear as the center line.
[0011] As a further improvement of the above solution, in a direction parallel to the axis of the gear, the length of the protrusion is not less than the length of the threaded connection.
[0012] As a further improvement of the above solution, anti-slip grooves are provided on the outer wall of the outer cover.
[0013] The utility model also provides a bottle, comprising a bottle body and a bottle cap for sealing the bottle mouth of the bottle body. The bottle cap is any of the above-mentioned anti-counterfeiting bottle caps.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] 1. Improved anti-counterfeiting performance: The use of threaded assembly combined with a reverse gear structure greatly increases the difficulty of disassembly, solving the technical problem of the inner and outer caps being easily separated. This effectively prevents counterfeiting and secondary use, and ensures product authenticity and brand reputation. During the screwing of the inner and outer caps, the protrusion continuously reduces the height difference with the gear. When the inner and outer caps are screwed together, the height difference decreases to a negative value, allowing the protrusion to engage with the gear through elastic deformation. At this point, the inner and outer caps are completely assembled and can no longer be unlocked by reversing the threads.
[0016] 2. Easy to assemble: Compared with traditional welding and hooking methods, the threaded assembly process is simple and efficient, reducing the defective rate in the production process and improving production efficiency. Compared with the existing bottle cap assembly process of welding and hooking, it has the outstanding effect of simple operation and high production efficiency.
[0017] 3. Easy to open: The traditional welding method is not used, thus avoiding the problems of inner cover deformation and excessive torque caused by high welding temperature, allowing consumers to easily open the bottle cap and improve the user experience.
[0018] 4. Stable structure: The combination of threaded connection and reverse tooth structure makes the connection between the inner cover and the outer cover more secure and less likely to separate, thus ensuring the anti-counterfeiting performance of the product.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are for the purpose of describing specific embodiments only and are not intended to limit this invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.
[0027] See also Figure 1 , which is a schematic cross-sectional view of a preferred embodiment of the anti-counterfeiting bottle cap provided by the present invention. The bottle cap and the bottle body (not shown) are the primary components of the bottle. The anti-counterfeiting bottle cap is used to seal the bottle mouth. The anti-counterfeiting bottle cap includes an outer cap 1, an inner cap 2, an inverted tooth structure 4, and may also include an assembly cap 3 for assembly over the bottle mouth. The assembly cap 3 is detachably assembled to the bottle neck.
[0028] Please combine Figure 2 、 Figure 3, the inner cover 2 is assembled inside the outer cover 1 by means of a threaded connection. The reverse tooth structure 4 is used to prevent the reversal between the outer cover 1 and the inner cover 2, and to prevent the outer cover 1 and the inner cover 2 from being unlocked by thread reversal. That is to say, in the bottle cap of the present invention, once the outer cover 1 and the inner cover 2 are locked by thread, due to the presence of the reverse tooth structure 4, the outer cover 1 and the inner cover 2 can no longer be unlocked by thread reversal. The threaded connection of this embodiment is specifically as follows: an internal thread 12 is provided on the inner wall of the outer cover 1, and an external thread 22 is provided on the outer wall of the inner cover 2 to be screwed together with the internal thread 12. An internal thread 23 can also be provided on the inner wall of the inner cover 2 to achieve threaded assembly with the assembly cover 3.
[0029] Before the bottle cap is assembled, the protrusion 11 does not mesh with the gear 21. Instead, it engages with the gear 21 through elastic deformation when the inner cap 2 and the outer cap 1 are threadedly connected. During the threaded assembly of the inner cap 2 and the outer cap 1, the protrusion 11 continuously reduces the height difference with the gear 21. When the inner cap 2 and the outer cap 1 are threaded together, the height difference decreases to a negative value, allowing the protrusion 11 to mesh with the gear 21 through elastic deformation. At this point, the inner cap 2 and the outer cap 1 are completely assembled, but the inner cap 2 and the outer cap 1 can no longer be unlocked by reversing the threads.
[0030] Please combine Figure 4 、 Figure 5 The inverted tooth structure 4 includes a gear 21 and at least one protrusion 11. Gear 21 is mounted on the outer wall of the inner cover 2 and fixed coaxially with the inner cover 2. For example, a through-hole is bored in the side of gear 21, through which gear 21 is mounted on the outer wall of the inner cover 2 and fixed coaxially with the inner cover 2. The protrusion 11 is fixed to the inner wall of the outer cover 1 and meshes with gear 21. The teeth on gear 21 are all inverted teeth, and the direction of the inverted teeth to prevent the protrusion 11 from rotating is the direction in which the threads of the outer cover 1 and inner cover 2 are twisted to open the cover.
[0031] This new invention utilizes a threaded assembly combined with a reverse tooth structure (4), significantly increasing the difficulty of disassembly. This solves the technical problem of the inner and outer caps of existing bottle caps being easily separated, effectively preventing counterfeiting and secondary use, and safeguarding product authenticity and brand reputation. Compared to traditional welding and hooking methods, the threaded assembly process is simpler and more efficient, reducing the defective rate during production and improving production efficiency.
[0032] The outer wall of the outer cover 1 can be provided with anti-slip grooves and anti-slip protrusions. The surfaces of the anti-slip grooves and anti-slip protrusions have vertical grooves. The vertical grooves can increase the friction of the outer wall of the outer cover 1, thereby achieving an anti-slip effect. The anti-slip protrusions are symmetrically arranged on the outer wall of the outer cover 1, which is equivalent to providing a lever arm with the center point of the outer cover 1 as a reference, facilitating the twisting and rotating operation of the outer cover 1, reducing the force required to open the wine bottle, and avoiding slipping when twisting the bottle cap. The anti-slip grooves and anti-slip protrusions can be integrally formed on the outer cover 1. Traditional welding methods are not used, thus avoiding the problems of deformation of the inner cover and excessive torque caused by high welding temperatures, allowing consumers to easily open the bottle cap and improving the user experience.
[0033] The gear 21 can be integrally formed on the outer wall of the inner cover 2 to enhance the structural strength of the inverted tooth structure 4. In order to improve the structural strength of the inverted tooth structure 4, the protrusion 11 can be integrally formed on the inner wall of the outer cover 1.
[0034] In this embodiment, the protrusion 11 can be strip-shaped to increase the contact area with the counter-tooth. The strip-shaped protrusion 11 can be parallel to the axis of the gear 21. In this way, during the threaded connection assembly process of the outer cover 1 and the inner cover 2, it will not affect the assembly effect of the threaded connection and will not increase the assembly resistance during the threaded connection.
[0035] The inverted tooth structure 4 can be set at any position of the bottle cap as long as it does not affect the threaded connection assembly of the outer cap 1 and the inner cap 2. In this embodiment, the threaded structure of the outer cap 1 and the inner cap 2 is preferably located on the side of the inverted tooth structure 4 facing the opening of the anti-counterfeiting bottle cap.
[0036] In this embodiment, a plurality of protrusions 11 are used as an example for illustration. If there are multiple protrusions 11, they can be evenly distributed in a ring shape with the axis of the gear 21 as the center line. Multiple groups of protrusions can also be formed, and the multiple groups are distributed as evenly as possible, thereby increasing the difficulty of demolition.
[0037] When threading the inner cover 2 and outer cover 1 together, the protrusion 11 must first be aligned with the counter-tooth on the gear 21, achieving a simultaneous threaded connection and meshing of the protrusion 11 with the gear 21. To ensure that the protrusion 11 is constantly engaged with the gear 21, the protrusion 11 must be short; in a direction parallel to the axis of the gear 21, the length of the protrusion 11 must be at least as long as the length of the threaded connection. During assembly, simply twisting the inner cover 2 and outer cover 1 relative to each other automatically achieves automatic meshing of the protrusion 11 with the gear 21, simultaneously with the threaded connection.
[0038] Compared to existing bottle cap assembly processes that rely on welding and hooking, this new design offers significant advantages in ease of operation and high production efficiency. By eliminating traditional welding, it avoids the problems of inner cap deformation and excessive torque caused by high welding temperatures, making it easier for consumers to open the bottle cap and enhancing the user experience. The combination of the threaded connection and the inverted tooth structure 4 provides a more secure connection between the inner cap 2 and the outer cap 1, preventing separation and ensuring the product's anti-counterfeiting performance.
[0039] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0040] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
