Description

Technical Field

[0001] This application relates to the field of packaging technology, and in particular to an anti-counterfeiting bottle cap and bottle container. Background Technology

[0002] With societal progress, people's demands for product packaging have gone beyond simply more refined appearances; they also require anti-counterfeiting features. For alcoholic beverages, especially high-end brands, an increasing number of criminals are manufacturing counterfeit products, using genuine packaging to deceive consumers. Therefore, various anti-counterfeiting packaging designs have become an indispensable part of the production process.

[0003] In the realm of high-value goods such as alcoholic beverages, anti-counterfeiting bottle caps are a core component ensuring product safety. Currently, anti-counterfeiting bottle caps often employ a connected-point structure with cuts on the outer cylinder as the primary anti-counterfeiting measure. The principle behind this is to set up a ring of break points at the connection between the outer cylinder of the cap and the bottle body. When a user opens the cap, the connected points break, creating irreversible physical damage marks, thus indicating whether the product has been illegally opened.

[0004] However, the anti-counterfeiting effect of the dotted structure is limited, relying solely on the physical destruction of the dotted structure as the basis for anti-counterfeiting. The dots are easily broken by external force or damaged by cutting tools. Counterfeiters can completely separate the bottle cap without triggering other anti-counterfeiting mechanisms, steal the internal code or replace the contents and reseal it, causing the anti-counterfeiting function to fail. Utility Model Content

[0005] Therefore, it is necessary to address the problem of poor anti-counterfeiting effect of the current anti-counterfeiting bottle cap with a dotted structure, and to provide an anti-counterfeiting bottle cap and bottle container that can play an anti-counterfeiting role when the anti-counterfeiting bottle cap is pulled upwards, thereby increasing the anti-counterfeiting effect, preventing the anti-counterfeiting function from failing, and increasing the difficulty for counterfeiters.

[0006] An anti-counterfeiting bottle cap is installed at the neck of a bottle in a bottle-type container, the anti-counterfeiting bottle cap comprising:

[0007] The inner sleeve is fixedly installed on the outside of the bottleneck.

[0008] The inner cover is rotatably mounted on the outside of the inner sleeve;

[0009] An anti-counterfeiting cap, fitted onto the inner cap, is capable of rotating the inner cap relative to the inner sleeve. The anti-counterfeiting cap is also capable of moving relative to the inner cap in a direction away from the bottleneck. The outer surface of the anti-counterfeiting cap has a first protrusion that protrudes away from the inner cap.

[0010] An outer sleeve covers the anti-counterfeiting cover, the inner cover, and the inner sleeve, and the anti-counterfeiting cover is fixedly installed. The outer sleeve can drive the anti-counterfeiting cover to move away from the bottleneck relative to the inner cover, and the inner cover can push the first protrusion towards the outer sleeve, so that the outer sleeve is deformed under the lifting of the first protrusion.

[0011] In one embodiment of this application, the anti-counterfeiting cover further includes a second protrusion, which protrudes from the surface of the anti-counterfeiting cover facing the inner cover and is disposed opposite to the first protrusion.

[0012] The inner cover has a first receiving hole on the surface facing the anti-counterfeiting cover. The second protrusion is installed in the first receiving hole. The second protrusion can abut against the wall of the first receiving hole so that the second protrusion pushes the inner cover to rotate relative to the inner sleeve. The second protrusion can also move out of the first receiving hole and move along the outer surface of the inner cover.

[0013] In one embodiment of this application, the outer surface of the inner cover also has a guide surface. The guide surface is disposed on the side of the first receiving hole away from the bottle body. The guide surface is inclined from the first receiving hole toward the direction away from the first receiving hole and toward the anti-counterfeiting cap. The guide surface is used to guide the second protrusion to move relative to the inner cover and push the second protrusion to drive the first protrusion to lift the outer sleeve.

[0014] In one embodiment of this application, the inner cover further has a second receiving hole, the second receiving hole being disposed on the side of the first receiving hole away from the bottleneck, the guide surface being disposed between the first receiving hole and the second receiving hole, and the second receiving hole being able to engage the second protrusion;

[0015] The distance between the top wall of the first receiving hole and the top wall of the second receiving hole ranges from 3mm to 7mm.

[0016] In one embodiment of this application, the anti-counterfeiting cover includes a cover body and a support member. The bottom of the cover body has an installation notch, and the support member is disposed on the top wall of the installation notch and has a gap between it and the side wall of the installation notch.

[0017] The support member is rotatable radially relative to the cover body, and the first protrusion is disposed on the surface of the support member facing the inner sleeve.

[0018] In one embodiment of this application, the first protrusion is provided in a pointed cone shape;

[0019] And / or, the second protrusion is cylindrical;

[0020] And / or, the inner cover includes a first cylinder and a second cylinder, the first cylinder and the second cylinder are coaxially arranged and connected, the second cylinder is rotatably installed on the outside of the inner sleeve, and the anti-counterfeiting cover is sleeved on the outside of the first cylinder;

[0021] And / or, the inner cover also has a first mounting hole and a second mounting hole, the first mounting hole being axially disposed on the outer surface of the inner cover, the second mounting hole being circumferentially disposed on the outer surface of the inner cover and communicating with the first mounting hole and the first receiving hole, the second protrusion being mounted in the first receiving hole through the first mounting hole and the second mounting hole;

[0022] The inner cover also includes a limiting member disposed in the second mounting hole and inclined toward the first receiving hole. The limiting member can guide the second protrusion from the second mounting hole to the first receiving hole, and the limiting member can also abut against the second protrusion in the first receiving hole.

[0023] In one embodiment of this application, the surface of the anti-counterfeiting cap facing away from the bottle body has a recessed glue injection groove, which contains glue to bond the anti-counterfeiting cap to the outer sleeve.

[0024] In one embodiment of this application, the glue injection groove includes a first glue groove and a plurality of second glue grooves. The first glue groove is located in the central region of the anti-counterfeiting cover, and the plurality of second glue grooves are circumferentially spaced at the edge of the first glue groove and communicate with the first glue groove.

[0025] In one embodiment of this application, the anti-counterfeiting bottle cap further includes an inner plug and a sealing cap. The inner plug is located in the inner sleeve and is sealed in the bottle mouth of the bottle body. The sealing cap is sealed in the inner sleeve. The anti-counterfeiting cap further includes a plurality of support ribs. The support ribs extend axially and are disposed on the inner side of the anti-counterfeiting cap. The support ribs can press against the sealing cap so that the sealing cap is sealed in the inner sleeve.

[0026] And / or, the anti-counterfeiting bottle cap further includes an inner cylinder, which is sleeved on the outside of the inner cap and the inner sleeve, and located inside the outer sleeve;

[0027] And / or, the inner sleeve includes a first sleeve and a second sleeve, the first sleeve and the second sleeve are coaxially arranged and connected, the second sleeve is fixedly installed on the bottleneck, and the inner cover is rotatably installed on the first sleeve.

[0028] A bottle-type container, comprising a bottle body and an anti-counterfeiting bottle cap as described in any of the above technical features;

[0029] The inner sleeve of the anti-counterfeiting bottle cap is fixedly installed at the bottleneck of the bottle body.

[0030] By adopting the above technical solution, this application has at least the following technical effects:

[0031] The present application discloses an anti-counterfeiting bottle cap and bottle container. In the anti-counterfeiting bottle cap, when the outer sleeve is twisted, the outer sleeve can drive the anti-counterfeiting cap and the inner cap to rotate relative to the inner sleeve, so that the anti-counterfeiting bottle cap can be opened or closed normally. When the anti-counterfeiting bottle cap is pulled up by an upward external force, the outer sleeve can drive the anti-counterfeiting cap to move away from the bottle body relative to the inner cap. At this time, the inner cap can push the first protrusion radially, so that the first protrusion moves towards the outer sleeve, and then the first protrusion can press against the outer sleeve, causing the outer sleeve to deform.

[0032] This anti-counterfeiting bottle cap features an additional anti-counterfeiting cap between the inner cap and the outer sleeve, with a first raised portion on the outer surface of the anti-counterfeiting cap. When the anti-counterfeiting bottle cap is pulled up by an upward force, the first raised portion deforms the outer sleeve, thus achieving the anti-counterfeiting function. In this way, when the anti-counterfeiting bottle cap is pulled upwards, it causes deformation or even damage to the outer sleeve, indicating to consumers that the anti-counterfeiting cap has been opened, preventing packaging material recycling, and achieving the purpose of preventing counterfeiting.

Detailed Implementation

[0052] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0053] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0054] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0055] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0056] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact, or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0057] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0058] Understandably, in the realm of high-value goods such as alcoholic beverages, anti-counterfeiting bottle caps are one of the core components ensuring product safety. Currently, anti-counterfeiting bottle caps often employ a connected-point structure with cuts on the outer cylinder as the primary anti-counterfeiting measure. The principle is to set up a ring of break points at the connection between the outer cylinder of the cap and the bottle body. When a user opens the cap, the connected points break, creating irreversible physical damage marks, thereby indicating whether the product has been illegally opened.

[0059] However, the anti-counterfeiting effect of the dotted structure is limited, relying solely on the physical destruction of the dotted structure as the basis for anti-counterfeiting. The dots are easily broken by external force or damaged by cutting tools. Counterfeiters can completely separate the bottle cap without triggering other anti-counterfeiting mechanisms, steal the internal code or replace the contents and reseal it, causing the anti-counterfeiting function to fail.

[0060] For this purpose, please refer to Figures 1 to 4 This application provides an anti-counterfeiting bottle cap 100. Figure 1 This is a front view of an anti-counterfeiting bottle cap 100 according to an embodiment of this application. Figure 2 for Figure 1 The cross-sectional view of the anti-counterfeiting bottle cap 100 shown along the AA direction. Figure 3 for Figure 2 The diagram shown is an exploded view of the anti-counterfeiting bottle cap 100 from one perspective. Figure 4 for Figure 3 The tamper-evident bottle cap 100 shown is a cross-sectional view along the BB direction. The tamper-evident bottle cap 100 is used in bottle containers and can be installed at the neck (not shown) of the bottle body (not shown) in the bottle container (not shown).

[0061] In this application, the bottle container is a wine bottle, and the anti-counterfeiting cap 100 is disposed at the neck of the bottle body, which can realize the sealing of the wine bottle. At the same time, the anti-counterfeiting cap 100 can also serve as an anti-counterfeiting function. Of course, in other embodiments of this application, the bottle container can also be other containers that need to serve an anti-counterfeiting function, such as cosmetic bottles, etc. The following description only uses a wine bottle as an example.

[0062] Understandably, the bottle capacity is not limited in principle; it can be 100ml, 200ml, or even 50ml, 350ml, 500ml, or other capacities. The anti-counterfeiting bottle cap 100 of this application serves an anti-counterfeiting function. When the anti-counterfeiting bottle cap 100 is pulled upwards, it will cause the outer sleeve 140 to deform or even be damaged, thus alerting the consumer that the bottle cap has been opened, preventing packaging material recycling, and achieving the purpose of preventing counterfeiting.

[0063] See Figures 1 to 5 In one embodiment, the anti-counterfeiting bottle cap 100 includes an inner sleeve 110, an inner cap 120, an anti-counterfeiting cap 130, and an outer sleeve 140. The inner sleeve 110 is fixedly installed on the outside of the bottle neck. The inner cap 120 is rotatably installed on the outside of the inner sleeve 110. The anti-counterfeiting cap 130 is sleeved on the inner cap 120, and the anti-counterfeiting cap 130 can drive the inner cap 120 to rotate relative to the inner sleeve 110. The anti-counterfeiting cap 130 can also move relative to the inner cap 120 in a direction away from the bottle neck. The outer surface of the anti-counterfeiting cap 130 has a first protrusion 131, which protrudes in a direction away from the inner cap 120.

[0064] The outer sleeve 140 is covered with an anti-counterfeiting cover 130, an inner cover 120 and an inner sleeve 110, and the anti-counterfeiting cover 130 is fixedly installed. The outer sleeve 140 can drive the anti-counterfeiting cover 130 to move away from the bottleneck relative to the inner cover 120, and the inner cover 120 can push the first protrusion 131 to move towards the outer sleeve 140, so that the outer sleeve 140 is deformed under the lifting of the first protrusion 131. Figure 5 for Figure 3 The diagram shows an exploded view of the anti-counterfeiting bottle cap 100 from another perspective.

[0065] The inner sleeve 110 is a component of the anti-counterfeiting bottle cap 100 that is installed on the bottle body. The inner sleeve 110 is fitted onto the bottle neck and fixedly installed there. The inner sleeve 110 cannot rotate relative to the bottle body. Moreover, the inner sleeve 110 also serves as a support for installation. Other components of the anti-counterfeiting bottle cap 100 cooperate with the bottle body through the inner sleeve 110, facilitating the installation of the anti-counterfeiting bottle cap 100 at the bottle neck and achieving sealing and anti-counterfeiting of the bottle body.

[0066] The outer sleeve 140 is the outer cylindrical body of the anti-counterfeiting bottle cap 100, the anti-counterfeiting cap 130 is the cap body that serves as an anti-counterfeiting measure, and the anti-counterfeiting cap 130 is fixedly installed in the outer sleeve 140. The inner cap 120 is the component that connects the anti-counterfeiting cap 130 and the inner sleeve 110. The inner cap 120 is rotatably installed on the outside of the inner sleeve 110, and the anti-counterfeiting cap 130 is installed on the outside of the inner cap 120. The outer sleeve 140 can drive the anti-counterfeiting cap 130 and the inner cap 120 to rotate relative to the inner sleeve 110, and the outer sleeve 140 can also drive the anti-counterfeiting cap 130 to move relative to the inner cap 120 in a direction away from the bottle body.

[0067] In this application, the outer sleeve 140 has axial, circumferential, and radial directions. The axial direction of the outer sleeve 140 is the direction of its central axis. Figures 1 to 5 The vertical direction of the anti-counterfeiting bottle cap 100 is shown above, while the circumferential direction of the outer sleeve 140 is the same as the circumferential direction of the outer sleeve 140. The radial direction of the outer sleeve 140 refers to the radial direction of the outer sleeve 140. When the anti-counterfeiting bottle cap 100 is pulled upward, it moves axially away from the bottle body.

[0068] The inner cap 120 is fitted over the inner sleeve 110, and the anti-counterfeiting cap 130 is fitted over the inner cap 120. The outer sleeve 140 completely covers the outer side of the anti-counterfeiting cap 130, the inner cap 120, and the inner sleeve 110 to protect them. When the anti-counterfeiting bottle cap 100 is opened normally, the outer sleeve 140 is turned. The outer sleeve 140 can drive the inner cap 120 to rotate through the anti-counterfeiting cap 130, thereby gradually loosening the inner cap 120 relative to the inner sleeve 110, allowing the anti-counterfeiting bottle cap 100 to open normally.

[0069] To enhance the anti-counterfeiting effect of the anti-counterfeiting bottle cap 100, this application provides a protruding first protrusion 131 on the outer surface of the anti-counterfeiting bottle cap 100. The first protrusion 131 extends radially and extends toward the outer sleeve 140. When the anti-counterfeiting bottle cap 100 is pulled upward, the outer sleeve 140 can drive the anti-counterfeiting cap 130 to move upward relative to the inner cap 120 (moving axially toward the direction away from the bottle neck).

[0070] During this process, the inner cap 120 can push the first protrusion 131 to extend radially away from the inner cap 120. The first protrusion 131 then abuts against the inner wall of the outer sleeve 140, pushing the outer sleeve 140 radially upwards. That is, the first protrusion 131 expands outwards, causing the outer sleeve 140 to bulge outwards under the action of the first protrusion 131, thus deforming the outer sleeve 140. In this way, the outer side of the outer sleeve 140 has a noticeable protrusion, indicating to consumers that the anti-counterfeiting cap 100 has been pulled upwards, thus serving an anti-counterfeiting function.

[0071] Thus, when the anti-counterfeiting bottle cap 100 is pulled upwards, the upward force of the outer sleeve 140 causes the first protrusion 131 on the anti-counterfeiting cap 130 to act on the outer sleeve 140, causing the outer sleeve 140 to deform significantly or even be damaged, thereby achieving the anti-counterfeiting function. In this way, when the outer sleeve 140 of the anti-counterfeiting bottle cap 100 is deformed or even damaged, it indicates that the anti-counterfeiting bottle cap 100 has been opened, thus alerting consumers that the anti-counterfeiting bottle cap 100 has been opened, preventing packaging material recycling, and increasing the anti-counterfeiting effect. Furthermore, counterfeiters cannot restore the anti-counterfeiting bottle cap 100 to its initial state after pulling it up, thus alerting consumers that the anti-counterfeiting bottle cap 100 has been opened, achieving the purpose of preventing counterfeiting.

[0072] See Figures 2 to 7 In one embodiment, the inner sleeve 110 includes a first sleeve 111 and a second sleeve 112. The first sleeve 111 and the second sleeve 112 are coaxially arranged and connected. The second sleeve 112 is fixedly installed on the bottleneck, and the inner cover 120 is rotatably installed on the first sleeve 111. Figure 6 for Figure 3 The diagram shows the inner sleeve 110 of the anti-counterfeiting bottle cap 100. Figure 7 for Figure 6 The inner sleeve 110 shown is a cross-sectional view along the CC direction.

[0073] The inner sleeve 110 is divided into two parts along the axial direction: an upper first sleeve 111 and a lower second sleeve 112. The first sleeve 111 and the second sleeve 112 are coaxially arranged and connected. The second sleeve 112 is fixedly installed at the neck of the bottle so that the inner sleeve 110 is fixed to the neck. The inner cap 120 is rotatably installed on the first sleeve 111 so that the inner cap 120 and the inner sleeve 110 are rotatably connected.

[0074] In one embodiment, the first sleeve 111 and the second sleeve 112 are an integral structure. This improves the structural strength of the inner sleeve 110, prevents breakage at the connection between the first sleeve 111 and the second sleeve 112, and simplifies the assembly process. Of course, in other embodiments of this application, the first sleeve 111 and the second sleeve 112 can also be separately disposed and reliably connected by means of adhesive bonding or other methods.

[0075] See Figures 2 to 5 , Figures 8 to 11 In one embodiment, the inner cover 120 includes a first cylindrical body 121 and a second cylindrical body 122, which are coaxially arranged and connected. The second cylindrical body 122 is rotatably installed on the outside of the inner sleeve 110, and the anti-counterfeiting cover 130 is sleeved on the outside of the first cylindrical body 121. Figure 8 for Figure 3 The image shown is a 3D view of the inner cap 120 within the anti-counterfeiting bottle cap 100. Figure 9 for Figure 8The front view of the inner cover 120 shown is shown. Figure 10 for Figure 9 The side view of the inner cover 120 shown is shown. Figure 11 for Figure 9 The inner cover 120 shown is a cross-sectional view along the DD direction.

[0076] The inner cap 120 is divided into two parts along the axial direction: an upper first cylindrical body 121 and a lower second cylindrical body 122. The first cylindrical body 121 and the second cylindrical body 122 are coaxially arranged and connected. The second cylindrical body 122 is rotatably installed on the outside of the first sleeve 111 of the inner sleeve 110, so that the inner cap 120 can be rotatably installed on the inner sleeve 110. The anti-counterfeiting cap 130 is installed on the outside of the first cylindrical body 121. The anti-counterfeiting cap 130 can be engaged with the first cylindrical body 121, so that the anti-counterfeiting cap 130 can drive the first cylindrical body 121 and the second cylindrical body 122 to rotate relative to the inner sleeve 110, thereby realizing the normal opening of the anti-counterfeiting bottle cap 100.

[0077] Because the second cylinder 122 is rotatably fixed to the first sleeve 111, when the anti-counterfeiting cap 100 is pulled up, the first sleeve 111 will limit the second cylinder 122, restricting the movement of the inner cap 120 on the line. As a result, the anti-counterfeiting cap 130 can detach from the first cylinder 121 and move along the outer surface of the first cylinder 121. At the same time, the outer surface of the first cylinder 121 can push the first protrusion 131 to lift the outer sleeve 140, so that the outer sleeve 140 is deformed, thus playing an anti-counterfeiting role.

[0078] In one embodiment, the first cylindrical body 121 and the second cylindrical body 122 are an integral structure. This improves the structural strength of the inner cover 120, prevents breakage at the connection between the first cylindrical body 121 and the second cylindrical body 122, and simplifies the assembly process. Of course, in other embodiments of this application, the first cylindrical body 121 and the second cylindrical body 122 can also be separately disposed and reliably connected by means of adhesive or other methods.

[0079] See Figures 2 to 11 In one embodiment, the outer surface of the first sleeve 111 is provided with external threads, and the inner wall of the second cylinder 122 is provided with internal threads. The first sleeve 111 and the second cylinder 122 are connected by threaded engagement. When the consumer normally opens the anti-counterfeiting bottle cap 100, he twists the outer sleeve 140. The outer sleeve 140 drives the first cylinder 121 and the second cylinder 122 to rotate through the anti-counterfeiting cap 130. In turn, the internal threads of the second cylinder 122 rotate along the external threads of the first sleeve 111, thereby opening the anti-counterfeiting bottle cap 100.

[0080] See Figures 1 to 5In one embodiment, the outer sleeve 140 is an aluminum sleeve. That is, the outer sleeve 140 is made of aluminum. In this way, after the first protrusion 131 pushes up the outer sleeve 140, the outer sleeve 140 can easily deform to indicate to the consumer that the anti-counterfeiting cap 100 has been pulled up and opened. Furthermore, the deformation of the aluminum outer sleeve 140 is not easily reversed, that is, after the outer sleeve 140 is deformed, it cannot return to its initial state, thus preventing the anti-counterfeiting function from failing, increasing the difficulty for counterfeiters to counterfeit, and making it easier for consumers to identify.

[0081] See Figures 1 to 5 In one embodiment, the outer sleeve 140 has an anti-counterfeiting connection point 141 at its lower part. The anti-counterfeiting connection point 141 is located near the bottom of the outer sleeve 140. When the outer sleeve 140 is twisted, the anti-counterfeiting connection point 141 can be disconnected, thus serving as an anti-counterfeiting measure.

[0082] See Figures 2 to 5 , Figures 12 to 16 In one embodiment, the anti-counterfeiting cover 130 includes a cover body 132 and a support member 133. The bottom of the cover body 132 has an installation notch, and the support member 133 is disposed on the top wall of the installation notch and has a gap between it and the side wall of the installation notch. A first protrusion 131 is disposed on the surface of the support member 133 facing the inner sleeve 110. Figure 12 for Figure 3 The diagram shows the anti-counterfeiting cap 130 in the anti-counterfeiting bottle cap 100. Figure 13 for Figure 12 The front view of the anti-counterfeiting cover 130 shown is shown. Figure 14 for Figure 13 The side view of the anti-counterfeiting cover 130 shown is shown. Figure 15 for Figure 13 The top view of the anti-counterfeiting cover 130 shown is shown. Figure 16 for Figure 15 The anti-counterfeiting cover 130 shown is a cross-sectional view along the EE direction.

[0083] The cap body 132 is the main component of the anti-counterfeiting bottle cap 100. The cap body 132 has the structural form of a bottle cap and is fixedly installed in the outer sleeve 140. Furthermore, the cap body 132 is fitted onto the outside of the first cylinder 121. The outer surface of the cap body 132 is provided with an installation notch, and the installation notch extends to the bottom of the cap body 132, that is, the installation notch presents a notch structure.

[0084] The support member 133 is located in the mounting notch, with its top connected to the top wall of the mounting notch, and a predetermined distance between its two sides and the side walls of the mounting notch. Thus, the support member 133 exhibits a cantilever structure within the mounting notch, allowing it to move radially relative to the cover body 132 when subjected to external force. A first protrusion 131 is provided on the outer surface of the support member 133.

[0085] When the anti-counterfeiting cap 100 is pulled upward, the outer sleeve 140 drives the anti-counterfeiting cap 130 to move upward. The inner surface of the support member 133 can abut against the outer surface of the inner cap 120 (the first cylinder 121, which will not be described in detail below). When the anti-counterfeiting cap 130 continues to move upward, the outer surface of the inner cap 120 can push the support member 133 to move radially toward the outer sleeve 140. Then, the support member 133 drives the first protrusion 131 to lift the outer aluminum cylinder, causing the outer sleeve 140 to deform, so as to play an anti-counterfeiting role.

[0086] In one embodiment, the cover body 132 and the support member 133 are integrally formed. That is, the cover body 132 and the support member 133 are integrally molded, and grooves are cut on both sides of the support member 133 to separate the sides of the support member 133 from the cover body 132, thereby allowing the support member 133 to move radially relative to the cover body 132. Optionally, the support member 133 is plate-shaped or sheet-shaped, and optionally, the support member 133 is a spring sheet.

[0087] See Figures 2 to 5 , Figures 8 to 16 In one embodiment, the anti-counterfeiting cover 130 further includes a second protrusion 134, which protrudes from the surface of the anti-counterfeiting cover 130 facing the inner cover 120, and is disposed opposite to the first protrusion 131. The surface of the inner cover 120 facing the anti-counterfeiting cover 130 has a first receiving hole 123, and the second protrusion 134 is installed in the first receiving hole 123. The second protrusion 134 can abut against the hole wall of the first receiving hole 123, so that the second protrusion 134 pushes the inner cover 120 to rotate relative to the inner sleeve 110. The second protrusion 134 can also move out of the first receiving hole 123 and move along the outer surface of the inner cover 120.

[0088] The second protrusion 134 is disposed opposite to the first protrusion 131, and is located on the inner surface of the anti-counterfeiting cover 130, extending toward the inner cover 120. Specifically, the second protrusion 134 is disposed on the surface of the support member 133 facing the inner cover 120. The second protrusion 134 can engage with the outer surface of the inner cover 120, so that the support member 133 pushes the first protrusion 131 to lift the outer sleeve 140.

[0089] Furthermore, the outer surface of the inner cap 120 also has a first receiving hole 123. Specifically, the first receiving hole 123 is located on the outer surface of the first cylindrical body 121 and corresponds to the second protrusion 134. After the anti-counterfeiting bottle cap 100 is assembled, the second protrusion 134 can be snapped into the first receiving hole 123, such as... Figure 2As shown, the second protrusion 134 can abut against the inner wall of the first receiving hole 123, and there is a gap between the first protrusion 131 and the inner surface of the outer sleeve 140. When the outer sleeve 140 is turned counterclockwise, the outer sleeve 140 drives the anti-counterfeiting cap 130 to rotate, and then the anti-counterfeiting cap 130 can push the inner wall of the first receiving hole 123 to rotate through the second protrusion 134, thereby driving the inner cap 120 to rotate relative to the inner sleeve 110, so as to realize the normal opening of the anti-counterfeiting bottle cap 100.

[0090] When the anti-counterfeiting bottle cap 100 is pulled upwards, the outer sleeve 140 moves the anti-counterfeiting cap 130 upwards simultaneously. Because the inner sleeve 110 limits the inner cap 120 through a threaded connection, the inner cap 120 will not move upwards. At this time, the second protrusion 134 can move out of the second receiving hole 125 under the upward pulling force and abut against the outer surface of the inner cap 120. Because the first receiving hole 123 is recessed relative to the outer surface of the inner cap 120, during this process, the outer surface of the inner cap 120 will push the second protrusion 134 to move radially toward the outer sleeve 140, so that the second protrusion 134 drives the support member 133 and the first protrusion 131 to move radially, thereby enabling the first protrusion 131 to push up the outer sleeve 140.

[0091] This application provides a second protrusion 134 on the inner surface of the anti-counterfeiting cap 130, with the second protrusion 134 and the first protrusion 131 arranged radially opposite to each other. A first receiving hole 123 is provided on the inner cap 120 at the position corresponding to the second protrusion 134. After the anti-counterfeiting cap 100 is assembled, the second protrusion 134 is located in the first receiving hole 123, and the first protrusion 131 does not contact the inner surface of the outer sleeve 140. When the anti-counterfeiting cap 100 is pulled upward, the upward outer wall causes the anti-counterfeiting cap 130 to move the second protrusion 134 away from the first receiving hole 123, and pushes the second protrusion 134 to move the first protrusion 131 toward the outer sleeve 140, so that the first protrusion 131 pushes up the outer sleeve 140, causing the outer sleeve 140 to deform and play an anti-counterfeiting role.

[0092] In one embodiment of this application, the first receiving hole 123 is provided radially through the first cylindrical body 121. That is, the first receiving hole 123 is a through hole. In this way, the second protrusion 134 can be snapped into the first receiving hole 123. Of course, in other embodiments of this application, the first receiving hole 123 may also be provided radially recessed on the outer surface of the first cylindrical body 121. That is, the first receiving hole 123 is a blind hole.

[0093] See Figure 2 , Figure 12 , Figure 13 and Figure 16In one embodiment, the first protrusion 131 is cone-shaped. That is, the end of the first protrusion 131 facing the outer sleeve 140 is pointed. In this way, when the first protrusion 131 pushes up the outer sleeve 140, the pointed end can more easily deform the outer sleeve 140, thereby improving the anti-counterfeiting effect.

[0094] See Figure 2 and Figure 16 In one embodiment, the second protrusion 134 is cylindrical. The cylindrical second protrusion 134 has high structural strength. Thus, when the outer sleeve 140 is twisted (counterclockwise), the outer sleeve 140 can drive the inner cap 120 to rotate relative to the inner sleeve 110 via the second protrusion 134 of the anti-counterfeiting cap 130. Simultaneously, when the anti-counterfeiting bottle cap 100 is pulled upwards, the inner cap 120 can also apply a lifting force to the first protrusion 131 via the second protrusion 134, causing the first protrusion 131 to lift the outer sleeve 140.

[0095] See Figure 2 , Figures 7 to 11 , Figure 17 In one embodiment, the outer surface of the inner cover 120 also has a guide surface 124. The guide surface 124 is disposed on the side of the first receiving hole 123 away from the bottle body. The guide surface 124 is inclined from the first receiving hole 123 toward the direction away from the first receiving hole 123 toward the anti-counterfeiting cap 130. The guide surface 124 is used to guide the second protrusion 134 to move relative to the inner cover 120 and push the second protrusion 134 to drive the first protrusion 131 to lift the outer sleeve 140. Figure 17 for Figure 2 The enlarged view of the anti-counterfeiting bottle cap 100 at point F is shown.

[0096] The guide surface 124 is inclined, which guides the second protrusion 134 to move upward along the axial direction, and at the same time, pushes the second protrusion 134 to move radially toward the outer sleeve 140. Figure 2 The right side and Figure 17 In the guide surface 124 shown, the guide surface 124 is inclined from the lower left to the upper right. In this way, when the anti-counterfeiting bottle cap 100 is pulled upward, the second protrusion 134 can be moved out from the first receiving hole 123 under the upward pulling force and abut against the guide surface 124.

[0097] As the outer sleeve 140 continues to move the anti-counterfeiting cover 130 upward, the anti-counterfeiting cover 130 can move the second protrusion 134 along the guide surface 124. During this process, since the guide surface 124 is inclined from the lower left to the upper right, the guide surface 124 can also push the second protrusion 134 to the right (towards the outer sleeve 140). That is, the second protrusion 134 can move upward and towards the outer sleeve 140 at the same time. Then, the second protrusion 134 can push the first protrusion 131 to lift the outer sleeve 140 through the support member 133, causing the outer sleeve 140 to deform.

[0098] In this embodiment, the guide surface 124 is an inclined plane. That is, the inclined plane guides the movement of the second protrusion 134, causing the second protrusion 134 to gradually move upwards and towards the outer sleeve 140. Of course, in other embodiments of this application, the guide surface 124 may also be a guide plane.

[0099] See Figure 2 , Figures 7 to 11 , Figure 17 In one embodiment, the inner cover 120 further has a second receiving hole 125, which is located on the side of the first receiving hole 123 away from the bottleneck. A guide surface 124 is located between the first receiving hole 123 and the second receiving hole 125. The second receiving hole 125 can engage the second protrusion 134. The outer surface of the inner cover 120 also has a second receiving hole 125. Specifically, the second receiving hole 125 is located on the outer surface of the first cylindrical body 121, and is also located above the first receiving hole 123. The second receiving hole 125 can achieve the engaging and limiting of the second protrusion 134.

[0100] When the anti-counterfeiting cap 100 is pulled upwards, the anti-counterfeiting cap 130 moves the second protrusion 134 out of the first receiving hole 123 and upwards along the guide surface 124. At the same time, the second protrusion 134 pushes the first protrusion 131 to lift the outer sleeve 140. After the anti-counterfeiting cap 130 moves the second protrusion 134 to the second receiving hole 125, the second protrusion 134 can be locked into the second receiving hole 125. There are no parts above or below the second receiving hole 125 to guide the second protrusion 134 out, so the second protrusion 134 is fixed in the second receiving hole 125 and cannot be moved out of the second receiving hole 125.

[0101] After the anti-counterfeiting bottle cap 100 is pulled upwards, the anti-counterfeiting cap 130 moves the second protrusion 134 from the first receiving hole 123 along the guide surface 124 into the second receiving hole 125. Because the second receiving hole 125 locks and limits the second protrusion 134, the anti-counterfeiting cap 130 cannot be lowered back down. Thus, the anti-counterfeiting bottle cap 100 remains in the upward-pulled state, which also serves to remind consumers that the anti-counterfeiting bottle cap 100 has been pulled upwards, thus fulfilling its anti-counterfeiting function.

[0102] In one embodiment of this application, the second receiving hole 125 is provided radially through the first cylindrical body 121. That is, the second receiving hole 125 is a through hole. In this way, the second protrusion 134 can be snapped into the second receiving hole 125. Of course, in other embodiments of this application, the second receiving hole 125 may also be provided radially recessed on the outer surface of the first cylindrical body 121. That is, the second receiving hole 125 is a blind hole.

[0103] In one embodiment, the distance between the top wall of the first receiving hole 123 and the top wall of the second receiving hole 125 is 3mm to 7mm. Thus, after the anti-counterfeiting bottle cap 100 is pulled upwards by 3mm to 7mm, the second protrusion 134 can move from the first receiving hole 123 along the guide surface 124 into the second receiving hole 125, thereby causing the outer sleeve 140 to rise by 3mm to 7mm as a whole. This significantly increases the height of the anti-counterfeiting bottle cap 100 after being pulled upwards, indicating to consumers that the anti-counterfeiting bottle cap 100 has been opened, thus serving its anti-counterfeiting function.

[0104] See Figures 8 to 11 In one embodiment, the inner cover 120 further has a first mounting hole 126 and a second mounting hole 127. The first mounting hole 126 is axially disposed on the outer surface of the inner cover 120, and the second mounting hole 127 is circumferentially disposed on the outer surface of the inner cover 120 and connects the first mounting hole 126 with the first receiving hole 123. The second protrusion 134 is mounted on the first receiving hole 123 through the first mounting hole 126 and the second mounting hole 127.

[0105] A first mounting hole 126 is vertically disposed on the outer wall of the first cylindrical body 121, and the first mounting hole 126 penetrates the top of the first cylindrical body 121. A second mounting hole 127 is circumferentially disposed on the outer wall of the first cylindrical body 121, one end of the second mounting hole 127 communicating with the bottom of the first mounting hole 126, and the other end of the second mounting hole 127 communicating with the first receiving hole 123. Thus, the first mounting hole 126 and the second mounting hole 127, when connected, roughly form an L-shaped form.

[0106] The first mounting hole 126 and the second mounting hole 127 facilitate the assembly between the second protrusion 134 and the inner cover 120. It is understood that the second protrusion 134 extends radially toward the inner cover 120 by a certain length, which prevents it from being installed into the first receiving hole 123. Therefore, this application provides the first mounting hole 126 and the second mounting hole 127 on the inner cover 120, facilitating the movement of the second protrusion 134 on the inner cover 120.

[0107] During assembly of the anti-counterfeiting cover 130, the second protrusion 134 is installed from the top of the inner cover 120 into the first mounting hole 126. The anti-counterfeiting cover 130 is then moved downwards so that the second protrusion 134 gradually moves from between the first mounting holes 126 into the second mounting hole 127. Subsequently, the anti-counterfeiting cover 130 is rotated counterclockwise so that the second protrusion 134 gradually moves from the second mounting hole 127 into the first receiving hole 123, thus completing the assembly of the anti-counterfeiting cover 130 and the inner cover 120.

[0108] Furthermore, when the outer sleeve 140 is turned counterclockwise, the outer sleeve 140 can also push the inner cover 120 to rotate through the second protrusion 134 on the anti-counterfeiting cap 130 and the inner wall of the first receiving hole 123, so that the inner cover 120 rotates relative to the inner sleeve 110, thereby opening the anti-counterfeiting bottle cap 100. Of course, when the anti-counterfeiting bottle cap 100 is pulled up, the second protrusion 134 can also move out of the first receiving hole 123 axially.

[0109] See Figures 8 to 11 , Figure 17 In one embodiment, the inner cover 120 further includes a limiting member 128, which is disposed in the second mounting hole 127 and inclined toward the first receiving hole 123. The limiting member 128 can guide the second protrusion 134 to move from the second mounting hole 127 to the first receiving hole 123, and the limiting member 128 can also abut against the second protrusion 134 in the first receiving hole 123.

[0110] A limiting member 128 is disposed in the second mounting hole 127 and inclined toward the first receiving hole 123. When the second protrusion 134 moves from the second mounting hole 127 to the first receiving hole 123, the second protrusion 134 can move along the limiting member 128 and press against the limiting member 128, so that the second protrusion 134 can move into the first receiving hole 123. After the second protrusion 134 moves into the first receiving hole 123, the limiting member 128 resets and extends toward the first receiving hole 123. At this time, the limiting member 128 can abut against the second protrusion 134, restricting the second protrusion 134 from moving from the first receiving hole 123 into the second mounting hole 127.

[0111] In other words, this application provides a limiting member 128 in the second mounting hole 127. The limiting member 128 does not affect the installation of the second protrusion 134. At the same time, the limiting member 128 can also limit the second protrusion 134 installed in the first receiving hole 123, thereby restricting the clockwise rotation of the anti-counterfeiting cap 130. In this way, after the anti-counterfeiting bottle cap 100 is assembled, the outer sleeve 140 can only drive the inner cap 120 to rotate counterclockwise through the anti-counterfeiting cap 130, and cannot rotate clockwise.

[0112] See Figure 2 , Figure 7 and Figure 16In this embodiment, two support members 133 are symmetrically arranged on the cover body 132 of the anti-counterfeiting cover 130. Each support member 133 has a first protrusion 131 and a second protrusion 134 arranged opposite to each other. Furthermore, two sets of first receiving holes 123, guide surfaces 124, second receiving holes 125, first mounting holes 126, second mounting holes 127, and limiting members 128 are symmetrically arranged on the cover body 132. Thus, the second protrusion 134 can cooperate with the corresponding first receiving hole 123, guide surface 124, second receiving hole 125, first mounting hole 126, second mounting hole 127, and limiting member 128. Of course, in other embodiments of this application, the number of first protrusions 131 may be one, three, or other numbers.

[0113] See Figures 12 to 16 In one embodiment, the anti-counterfeiting cap 130 has a recessed glue injection groove 135 on the surface opposite to the bottle body. The glue injection groove 135 contains glue to bond the anti-counterfeiting cap 130 to the outer sleeve 140. That is, the top of the cap body 132 has a recessed glue injection groove 135. After the anti-counterfeiting cap 130 is assembled onto the inner cap 120, glue is injected into the glue injection groove 135. Subsequently, the outer sleeve 140 is fitted onto the anti-counterfeiting cap 130. At this time, the glue in the glue injection groove 135 can contact the inner surface of the outer sleeve 140, bonding the anti-counterfeiting cap 130 to the outer sleeve 140, thereby enabling the outer sleeve 140 to move synchronously with the anti-counterfeiting cap 130.

[0114] See Figures 12 to 16 In one embodiment, the glue injection groove 135 includes a first glue groove 1351 and a plurality of second glue grooves 1352. The first glue groove 1351 is located in the central region of the anti-counterfeiting cover 130, and the plurality of second glue grooves 1352 are circumferentially spaced at the edge of the first glue groove 1351 and communicate with the first glue groove 1351. The first glue groove 1351 is located in the central region of the top of the cover body 132, and the second glue grooves 1352 are located at the edge of the first glue groove 1351 and communicate with the first glue groove 1351. Furthermore, the second glue grooves 1352 extend to the edge of the cover body 132.

[0115] In this way, after the adhesive is injected into the first adhesive groove 1351, the adhesive can fill the first adhesive groove 1351 and the second adhesive groove 1352. At the same time, the adhesive can also flow along the second adhesive groove 1352 to the edge of the cover body 132, so that the cover body 132 is also bonded to the outer sleeve 140 at the edge by the adhesive, thereby improving the reliability of the connection between the anti-counterfeiting cover 130 and the outer sleeve 140.

[0116] See Figures 2 to 5 , Figure 16 , Figure 18In one embodiment, the anti-counterfeiting bottle cap 100 further includes an inner plug 150 and a sealing cap 160. The inner plug 150 is located in the inner sleeve 110 and is sealed in the bottle mouth of the bottle body. The sealing cap 160 is sealed in the inner sleeve 110. The anti-counterfeiting cap 130 also includes a plurality of support ribs 136. The support ribs 136 extend axially and are disposed on the inner side of the anti-counterfeiting cap 130. The support ribs 136 can press against the sealing cap 160 so that the sealing cap 160 is sealed in the inner sleeve 110. Figure 18 for Figure 2 The enlarged view of the anti-counterfeiting bottle cap 100 at point G.

[0117] The inner plug 150 is installed at the bottle mouth of the bottle body. The inner plug 150 is located inside the inner sleeve 110 and can be sealed into the bottle mouth, thus achieving a preliminary seal on the bottle body. The sealing cap 160 is a component that achieves a secondary seal on the bottle body. The sealing cap 160 is installed on the top of the first sleeve 111 in the inner sleeve 110, and the sealing cap 160 seals the opening at the top of the first sleeve 111.

[0118] Furthermore, the inner side of the anti-counterfeiting cap 130 is provided with an axially extending support rib 136. After the anti-counterfeiting cap 130 is assembled into the inner cap 120, the bottom of the support rib 136 can press against the sealing cap 160, so that the sealing cap 160 is sealed and installed on the top of the inner sleeve 110. Even if the bottle is inverted, the liquid in the bottle, such as wine, will not leak from the gap between the inner sleeve 110 and the sealing cap 160. When the anti-counterfeiting cap 100 is pulled up, the anti-counterfeiting cap 130 moves upward from the first receiving hole 123 to the second receiving hole 125. The anti-counterfeiting cap 130 will drive the support rib 136 to move upward synchronously, and the support rib 136 will disengage from the sealing cap 160.

[0119] At this point, the support rib 136 no longer presses against the sealing cap 160, causing the sealing cap 160 to loosen within the inner sleeve 110. When the bottle is inverted, liquids such as wine will leak from the gap between the inner sleeve 110 and the sealing cap 160, resulting in leakage. This renders the liquid-filled bottle unsellable and also serves as an anti-counterfeiting measure.

[0120] In one embodiment, the anti-counterfeiting bottle cap 100 further includes an inner cylinder 170, which is sleeved on the outside of the inner cap 120 and the inner sleeve 110, and located inside the outer sleeve 140. The inner cylinder 170 is sleeved on the outside of the second cylinder 122 and the inner sleeve 110, and located inside the outer sleeve 140. The inner cylinder 170 is a cylindrical structure with openings at both ends.

[0121] When the anti-counterfeiting bottle cap 100 is opened normally, the inner sleeve 110 is broken at the connection point, thus serving as an anti-counterfeiting measure. Furthermore, the outer sleeve 140 covers the anti-counterfeiting cap 130 and the inner sleeve 170. At this time, all other components of the anti-counterfeiting bottle cap 100 are located inside the outer sleeve 140, which protects the internal components of the anti-counterfeiting bottle cap 100 from being pried open.

[0122] Furthermore, when the anti-counterfeiting bottle cap 100 is pulled upwards, the outer sleeve 140 causes the anti-counterfeiting cap 130 to move upwards as a whole. At this time, the bottom of the inner sleeve 170 will be exposed through the outer sleeve 140, which serves as a reminder to consumers that the anti-counterfeiting bottle cap 100 has been pulled upwards, thus playing the role of anti-counterfeiting reminder.

[0123] In one embodiment, the inner cylinder 170 is an aluminum cylinder. That is, the inner cylinder 170 is made of aluminum. After connecting points are set at corresponding positions in the inner cylinder 170, the connecting points can be broken when the anti-counterfeiting cap 100 is opened normally. In one embodiment, the inner stopper 150, sealing cap 160, inner sleeve 110, inner cap 120, and anti-counterfeiting cap 130 are injection molded from thermoplastic materials.

[0124] The anti-counterfeiting bottle cap 100 of this application has a first protrusion 131 on the outer surface of the anti-counterfeiting cap 130. When the anti-counterfeiting bottle cap 100 is pulled upward, the outer sleeve 140 drives the anti-counterfeiting cap 130 to move upward. At the same time, the inner cap 120 can push the first protrusion 131 to move towards the outer sleeve 140, so that the second protrusion 134 can lift the sleeve, causing the outer sleeve 140 to deform or even be damaged, so as to indicate to the consumer that the anti-counterfeiting bottle cap 100 has been opened, thus playing an anti-counterfeiting role.

[0125] Meanwhile, this application also provides a first receiving hole 123 on the inner cover 120 and a second protrusion 134 on the inner surface of the anti-counterfeiting cover 130. The second protrusion 134 is positioned opposite to the first protrusion 131 and can be installed into the first receiving hole 123. When the anti-counterfeiting bottle cap 100 is opened normally, the outer sleeve 140 is turned, and the inner cover 120 is opened relative to the inner sleeve 110 through the cooperation of the second protrusion 134 in the anti-counterfeiting cover 130 and the first receiving hole 123.

[0126] Furthermore, the inner cap 120 is also provided with a guide surface 124 and a second guide hole. When the anti-counterfeiting bottle cap 100 is pulled up, the second protrusion 134 can move out of the first receiving hole 123 and slide upward along the guide surface 124. At the same time, the guide surface 124 can push the second protrusion 134 radially, so that the second protrusion 134 drives the first protrusion 131 to lift the outer sleeve 140, thereby playing an anti-counterfeiting role.

[0127] When the outer sleeve 140 moves the second protrusion 134 to the second receiving hole 125 through the anti-counterfeiting cap 130, the second protrusion 134 will be locked in the second receiving hole 125. At this time, the anti-counterfeiting bottle cap 100 cannot be pulled up or reset down. The anti-counterfeiting bottle cap 100 rises to a certain height and exposes the inner cylinder 170 below, which can also play an anti-counterfeiting role.

[0128] Furthermore, after the anti-counterfeiting cap 130 moves upward, the anti-counterfeiting cap 130 will cause the support rib 136 to disengage from the sealing cap 160. At this time, the sealing cap 160 will loosen in the inner sleeve 110. After the bottle container is inverted, the bottle container will leak wine, which can also play an anti-counterfeiting role.

[0129] When the anti-counterfeiting bottle cap 100 of this application is pulled upwards, the first protrusion 131 pushes up the outer sleeve 140, causing the outer sleeve 140 to deform or even be damaged. The deformation of the outer sleeve 140 cannot be reversed, thus providing a first layer of anti-counterfeiting protection. After the anti-counterfeiting bottle cap 100 continues to be pulled upwards, the second protrusion 134 will engage in the second receiving hole 125, preventing the anti-counterfeiting bottle cap 100 from returning to its original position. At this point, the anti-counterfeiting bottle cap 100 rises to a certain height, exposing the inner sleeve 170 below, thus providing a second layer of anti-counterfeiting protection. Simultaneously, the support rib 136 on the anti-counterfeiting cap 130 detaches from the sealing cap 160, potentially causing leakage, thus providing a third layer of anti-counterfeiting protection.

[0130] Thus, the anti-counterfeiting bottle cap 100 of this application achieves its anti-counterfeiting function through a combination of multiple anti-counterfeiting measures, increasing the anti-counterfeiting effect and preventing the anti-counterfeiting function from failing, thereby increasing the difficulty for counterfeiters. In this way, counterfeiters cannot restore the anti-counterfeiting bottle cap 100 to its initial state after removing it, thus reminding consumers that the anti-counterfeiting bottle cap 100 has been opened, preventing packaging material recycling, and achieving the purpose of preventing counterfeiting.

[0131] This application also provides a bottle container, including a bottle body and an anti-counterfeiting bottle cap 100 as described in any of the above embodiments. The inner sleeve 110 of the anti-counterfeiting bottle cap 100 is fixedly installed at the neck of the bottle body. By using the anti-counterfeiting bottle cap 100 of the above embodiments, the bottle container of this application can enhance the anti-counterfeiting effect, prevent the anti-counterfeiting function from failing, and increase the difficulty for counterfeiters. Thus, counterfeiters cannot restore the anti-counterfeiting bottle cap 100 to its initial state after removing it, thereby alerting consumers that the anti-counterfeiting bottle cap 100 has been opened, preventing packaging material recycling, and achieving the purpose of preventing counterfeiting.

[0132] The technical features of the above embodiments can be combined in any way. For the sake of brevity, 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.

[0133] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
