Description

Technical Field

[0001] This invention relates to the field of anti-counterfeiting technology for bottle caps, and more specifically, to an anti-counterfeiting outer cap assembly, a bottle cap, and a wine bottle. Background Technology

[0002] The anti-counterfeiting performance of baijiu products directly affects the identification of genuine products and brand reputation. Therefore, anti-counterfeiting bottle caps are widely used in baijiu products. Existing anti-counterfeiting bottle caps usually include an inner sleeve, an inner cap, and an outer cap assembly. The outer cap assembly is usually composed of an upper outer cap and a lower outer cap (the upper and lower outer caps have different names in different existing technologies. For example, in patent document "CN223253757U", they are called outer cap and outer sleeve; in patent document "CN221368517U", they are called outer cap and lower tube; in patent document "CN222592251U", they are called anti-counterfeiting upper cap and anti-counterfeiting lower cap; and in patent document "CN120607035A", they are called upper cap and lower sleeve. Hereinafter, they are collectively referred to as upper outer cap and lower outer cap).

[0003] Most existing anti-counterfeiting structures involve setting an anti-counterfeiting flap (also known as an anti-counterfeiting tooth, anti-counterfeiting block, etc., hereinafter collectively referred to as an anti-counterfeiting flap) between the upper and lower outer caps. When the bottle cap is pulled or twisted, the anti-counterfeiting flap will be irreversibly damaged, thereby achieving the purpose of anti-counterfeiting.

[0004] However, since the anti-counterfeiting flap is usually made of a plastic material with a certain degree of elasticity, and there is a gap between the anti-counterfeiting flap and the notch of the upper outer cover, criminals may use tools to pry the anti-counterfeiting flap outward without damaging it, so that it temporarily disengages from the matching position with the notch of the upper outer cover. Thus, when the upper outer cover is rotated, the anti-counterfeiting flap is no longer subjected to the shearing force of the notch, and the upper outer cover can be rotated open without damaging the anti-counterfeiting flap, which seriously weakens the reliability of the anti-counterfeiting structure. Summary of the Invention

[0005] The purpose of this invention is to provide an anti-counterfeiting outer cap assembly, bottle cap, and wine bottle to overcome the above-mentioned defects of the prior art.

[0006] This invention is achieved through the following technical solution:

[0007] An anti-counterfeiting outer cover assembly includes an upper outer cover and a lower outer cover, and also includes an anti-counterfeiting ring, wherein the lower outer cover is fitted over the anti-counterfeiting ring and the upper outer cover is fitted over the lower outer cover. The outer wall of the anti-counterfeiting ring has an outwardly protruding anti-counterfeiting petal, and the side wall of the upper outer cover has an anti-counterfeiting window. The anti-counterfeiting petal protrudes through the lower outer cover and is housed in the anti-counterfeiting window so that it will break when the upper outer cover is pulled or twisted.

[0008] Furthermore, the side wall of the lower outer cover is provided with a positioning window, the outer wall of the anti-counterfeiting ring is provided with a positioning block that cooperates with the positioning window, and the anti-counterfeiting petal is provided on the positioning block.

[0009] Furthermore, the inner wall of the upper outer cover is provided with a positioning step that abuts against the top surface of the lower outer cover. One of the positioning step and the top surface of the lower outer cover is provided with a plurality of positioning holes, and the other is provided with a positioning pin that cooperates with the positioning holes. When the upper outer cover is screwed open, the positioning pin can be broken off.

[0010] Furthermore, the outer side of the anti-counterfeiting flap is provided with an indicator mark to indicate the opening and / or closing direction of the upper outer cover.

[0011] Furthermore, the inner diameter of the lower end of the outer cover is larger than the outer diameter of the anti-counterfeiting ring.

[0012] Furthermore, the inner wall of the lower outer cover is provided with a limiting step that abuts against the top surface of the anti-counterfeiting ring.

[0013] The present invention also provides a bottle cap, comprising an inner sleeve, an inner plug, an inner cap, and an anti-counterfeiting outer cap assembly as described in any one of the above. The inner plug is embedded inside the inner sleeve, the inner cap is connected to the upper end of the inner sleeve by a thread, the lower outer cap is fixedly sleeved on the lower end of the inner sleeve, and the upper outer cap is fixedly sleeved on the outside of the inner cap.

[0014] Furthermore, the inner wall of the anti-counterfeiting ring is provided with a plurality of hanging platforms along the circumferential direction, and the outer wall of the inner sleeve is provided with a limiting ring groove that cooperates with the hanging platforms. The present invention also provides a wine bottle, comprising a bottle body and a bottle cap as described in any of the above claims.

[0015] The technical solution of this invention has at least the following advantages and beneficial effects: In this invention, by having the anti-counterfeiting petal on the outer wall of the anti-counterfeiting ring pass through the side wall of the lower outer cap and directly extend into the anti-counterfeiting window of the upper outer cap, a forced mechanical limiting structure is formed in which the anti-counterfeiting petal penetrates the lower outer cap and is inserted into the upper outer cap. Under this structure, even if criminals apply an external force to pry open or laterally push the anti-counterfeiting petal from the outside, since the anti-counterfeiting petal always penetrates the lower outer cap and its end is accommodated in the anti-counterfeiting window, the circumferential interference relationship between the anti-counterfeiting petal and the anti-counterfeiting window of the upper outer cap will not be eliminated by external prying. When the upper outer cap is twisted or pulled open, the anti-counterfeiting window of the upper outer cap will inevitably interfere with the anti-counterfeiting petal, thereby forming an unavoidable shearing or tensile force on the anti-counterfeiting petal, forcing the anti-counterfeiting petal to break, eliminating the possibility of criminals opening the bottle cap without damaging the anti-counterfeiting petal, and improving the reliability of anti-counterfeiting.

Detailed Implementation

[0017] Example 1 refer to Figures 1-5 This embodiment provides an anti-counterfeiting outer cover assembly, including an upper outer cover 1, a lower outer cover 2, and an anti-counterfeiting ring 3. The lower outer cover 2 is fitted over the anti-counterfeiting ring 3, and the upper outer cover 1 is fitted over the lower outer cover 2. That is, the outer wall of the lower outer cover 2 fits with the inner wall of the upper outer cover 1, and the inner wall of the lower outer cover 2 fits with the outer wall of the anti-counterfeiting ring 3.

[0018] The outer wall of the anti-counterfeiting ring 3 has an outwardly protruding anti-counterfeiting flap 301, which is integrally injection molded with the anti-counterfeiting ring 3. The side wall of the upper outer cover 1 has an anti-counterfeiting window 101. The anti-counterfeiting flap 301 protrudes through the lower outer cover 2 and is housed in the anti-counterfeiting window 101, so that it will break when the upper outer cover 1 is pulled or twisted. In practical applications, in order to ensure that the anti-counterfeiting flap 301 breaks, the anti-counterfeiting flap 301 and the anti-counterfeiting ring 3 are connected by several connecting ribs (which is equivalent to the anti-counterfeiting flap 301 and the outer wall of the anti-counterfeiting ring 3 being hollow). It should be understood that "the anti-counterfeiting flap 301 breaks" means that the connecting ribs break, and the anti-counterfeiting flap 301 separates from the anti-counterfeiting ring 3.

[0019] It is worth noting that the anti-counterfeiting flap 301 penetrates the lower outer cover 2 and is inserted into the upper outer cover 1 through a forced mechanical limiting structure. Even if criminals apply an external force to pry open or laterally push the anti-counterfeiting flap 301, the circumferential interference between the anti-counterfeiting flap 301 and the anti-counterfeiting window 101 of the upper outer cover 1 will not be eliminated by external prying because the anti-counterfeiting flap 301 always penetrates the lower outer cover 2 and its end is accommodated in the anti-counterfeiting window 101. When the upper outer cover 1 is twisted or pulled open, the anti-counterfeiting window 101 of the upper outer cover 1 will inevitably interfere with the anti-counterfeiting flap 301, thereby creating an unavoidable shearing or tensile force on the anti-counterfeiting flap 301, forcing the anti-counterfeiting flap 301 to break. This eliminates the possibility of criminals opening the bottle cap without damaging the anti-counterfeiting flap 301, thus improving the reliability of anti-counterfeiting measures.

[0020] The lower outer cover 2 has a through positioning window 201 on its side wall. The outer wall of the anti-counterfeiting ring 3 has a positioning block 302 that mates with the positioning window 201, and the anti-counterfeiting flap 301 is located on the positioning block 302. During assembly, the anti-counterfeiting flap 301 passes through the positioning window 201 of the lower outer cover 2 and finally extends into the anti-counterfeiting window 101 of the upper outer cover 1. The positioning block 302 then mates with the positioning window 201 to achieve circumferential positioning between the anti-counterfeiting ring 3 and the lower outer cover 2. Furthermore, the inner wall of the lower outer cover 2 has a limiting step 203 that abuts against the top surface of the anti-counterfeiting ring 3 to achieve accurate axial positioning of the anti-counterfeiting ring 3. In addition, the inner diameter of the lower end of the lower outer cover 2 (it should be understood that "upper" and "lower" are defined according to the state in which the bottle is placed upright during actual use) is designed to be larger than the outer diameter of the anti-counterfeiting ring 3, that is, there is a radial gap between the two, which facilitates pushing the anti-counterfeiting ring 3 into the lower outer cover 2 to its mating position during assembly.

[0021] The inner wall of the upper outer cover 1 has a downwardly extending positioning step 102, which abuts against the top surface of the lower outer cover 2 after assembly. In this embodiment, multiple positioning pins 202 are arranged circumferentially on the top surface of the lower outer cover 2, and positioning holes 1021 are correspondingly provided on the positioning step 102 of the upper outer cover 1. It should be understood that in other embodiments, the positioning pins 202 can be set on the positioning step 102 of the upper outer cover 1, and the positioning holes 1021 can be set on the top surface of the lower outer cover 2. During actual assembly, the positioning pins 202 are inserted into the positioning holes 1021, and the friction between the positioning pins 202 and the positioning holes 1021 is used to temporarily fix the upper outer cover 1 and the lower outer cover 2 into a whole, which facilitates the subsequent assembly process. In addition, when the consumer unscrews and opens the upper outer cover 1, the positioning pins 202 are broken by shearing force, which can also serve as an auxiliary anti-counterfeiting verification.

[0022] To facilitate correct operation by consumers, the outer side of the anti-counterfeiting cap 301 is equipped with indicator markings. These markings can be arrows or text (such as "open," "close," "OFF," "ON," etc.), or a combination of arrows and text, making it easy for users to twist the cap correctly according to the instructions. It is easy to understand that the indicator markings can indicate only the opening direction (the opposite direction is the closing direction), or only the closing direction (the opposite direction is the opening direction), or of course, both the opening and closing directions can be indicated simultaneously.

[0023] Example 2 refer to Figure 6 This embodiment provides a bottle cap, including an inner sleeve 4, an inner plug 5, an inner cap 6, and an anti-counterfeiting outer cap assembly provided in Embodiment 1.

[0024] The upper end of the inner plug 5 is embedded inside the inner sleeve 4, forming a sealing pair with the inner wall of the inner sleeve 4. In practical applications, the lower end of the inner plug 5 is embedded inside the bottle mouth, forming a sealing pair with the inner wall of the bottle mouth. The inner cap 6 is connected to the upper end of the inner sleeve 4 by threads. The lower outer cap 2 is fixedly fitted onto the lower end of the inner sleeve 4, and the upper outer cap 1 is fixedly fitted onto the outside of the inner cap 6. The connection method between the lower outer cap 2 and the inner sleeve 4, and between the upper outer cap 1 and the inner cap 6, is not limited. Commonly used methods in the art can be adopted, such as using mutually cooperating anti-rotation ribs to restrict circumferential relative rotation, and using mutually cooperating locking blocks and slots to restrict axial relative movement. Those skilled in the art should understand that the above-mentioned composition of the bottle cap is only an option and not a limitation. Those skilled in the art can certainly add or remove components according to actual needs. Those skilled in the art also naturally know that the bottle cap is not limited to the above-mentioned anti-counterfeiting outer cap assembly for anti-counterfeiting. In practical applications, it can certainly be combined with other anti-counterfeiting structures for joint anti-counterfeiting.

[0025] Based on the above, in this embodiment, the inner wall of the anti-counterfeiting ring 3 is provided with several hanging platforms 303 along the circumferential direction, and the outer wall of the inner sleeve 4 is provided with a limiting ring groove that cooperates with the hanging platforms 303. The cooperation between the hanging platforms 303 and the limiting ring groove mainly serves the purpose of assembly and positioning. During the bottle cap assembly process, the hanging platforms 303 are engaged in the limiting ring groove, so that the anti-counterfeiting ring 3 and the inner sleeve 4 form a whole, preventing the anti-counterfeiting ring 3 from falling downwards due to gravity in subsequent processes, that is, preventing the limiting ring from being misaligned axially. It is worth noting that before the entire bottle cap is pressed onto the bottle mouth, the anti-counterfeiting ring 3 needs to be kept in the correct position. If the anti-counterfeiting ring 3 is misaligned axially, it will cause the anti-counterfeiting flap 301 to deviate from the preset position, thereby affecting the capping accuracy or even causing the product to be scrapped. In this embodiment, the cooperation between the hanging platforms 303 and the limiting ring groove effectively avoids this problem.

[0026] Example 3 This embodiment provides a wine bottle, including a bottle body 7 and a bottle cap as provided in Embodiment 2. As described above, the lower end of the inner plug 5 of the bottle cap is embedded inside the bottle mouth, forming a sealing pair with the inner wall of the bottle mouth. In addition, those skilled in the art should understand that the inner sleeve 4 should engage with the outer side of the bottle mouth, and the specific method is not limited. For example, it can be done by setting claws on the inner sleeve 4 to engage with the corresponding grooves on the outer side of the bottle mouth, as is done in the prior art.

[0027] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
