Description

Technical Field

[0001] This utility model relates to the field of bottle cap technology, specifically to an anti-counterfeiting bottle cap with a highly efficient anti-backflow (anti-refill) function, and a wine bottle containing the bottle cap. Background Technology

[0002] Existing anti-counterfeiting bottle caps, such as the structure disclosed in Chinese Utility Model Patent Application No. 201921723320.4 (Authorization Announcement No. CN210913607U), typically include an inner stopper, a glass bead (or check ball) disposed inside the inner stopper, and a one-way valve disposed above the glass bead.

[0003] During normal pouring, the liquid pushes the glass bead upwards, opening the one-way valve and allowing the liquid to flow out from the spout. When pouring stops, the glass bead and one-way valve fall back under gravity. The one-way valve acts like a lid, covering the opening of the inner stopper. Simultaneously, when the outer cap (such as an infrared cap) is tightened, its internal column pushes downwards against the one-way valve, creating a seal and preventing backflow of liquid.

[0004] However, in practice, the inventors discovered a serious security vulnerability in the existing anti-counterfeiting structure. The existing "pot lid" type one-way valve, after the outer cap of the bottle is opened, will tip over or flip over if the bottle is placed horizontally (i.e., laid flat) due to its unbalanced structure, preventing it from sealing the inner stopper opening. Criminals can then use pressure (e.g., by squeezing with a mineral water bottle) to refill the bottle with counterfeit liquor through this channel, severely harming the interests of consumers and manufacturers. Utility Model Content

[0005] The main objective of this invention is to provide an anti-backflow and anti-counterfeiting bottle cap to solve the technical problem mentioned in the background art that existing bottle cap structures can be easily refilled when in a "flat" state.

[0006] To achieve the above objectives, this utility model provides an anti-backflow and anti-counterfeiting bottle cap, comprising:

[0007] The inner plug defines a cavity for accommodating at least one check ball;

[0008] At least one check ball is disposed within the cavity;

[0009] A one-way valve is movable up and down above the check ball, which is opened by the check ball when pouring wine and closed when pouring stops.

[0010] The one-way valve includes:

[0011] Valve body, used to close the opening of the inner plug when the one-way valve is in the closed position; and

[0012] A limiting element, which is fixedly connected to the valve body and extends downward into the cavity of the inner plug, and at least partially covers the at least one check ball, so that when the bottle cap is placed horizontally, the one-way valve forms a balanced counterweight by means of its limiting element and the internal check ball to keep the valve body and the opening of the inner plug of the one-way valve in a closed state.

[0013] In one embodiment, the limiting member is cylindrical.

[0014] In one embodiment, the limiting member is provided with a plurality of sieve holes.

[0015] In one embodiment, the at least one anti-reverse ball includes an upper anti-reverse ball and a lower anti-reverse ball; the limiting member is configured to cover and restrict the radial movement of the upper anti-reverse ball.

[0016] In one embodiment, the inner wall of the inner plug is provided with multiple guide ribs, which together define a guide track for limiting the radial movement of the lower anti-reverse ball.

[0017] In one embodiment, the cavity includes an upper cavity and a lower cavity, the inner diameter of the upper cavity is larger than the inner diameter of the lower cavity, the lower end of the limiting member extends into the upper cavity, and the multiple guide ribs are disposed on the inner wall of the lower cavity.

[0018] In one embodiment, the bottle cap further includes a spout disposed on the inner stopper; the spout is provided with multiple dispensing holes.

[0019] In one embodiment, the plurality of dispensing holes includes at least one first dispensing hole and a plurality of second dispensing holes, wherein the at least one first dispensing hole is located in the middle of the dispensing nozzle, and the plurality of second dispensing holes are arranged around the at least one first dispensing hole.

[0020] In one embodiment, the plurality of second wine outlet holes are arranged in two rings, and the arrangement of the two rings of wine outlet holes is staggered.

[0021] A wine bottle, comprising a bottle body and a backflow prevention and anti-counterfeiting cap.

[0022] Compared with the prior art, the anti-backflow and anti-counterfeiting bottle cap provided by this utility model has the following outstanding advantages:

[0023] 1. Solves the major loophole of "backflow when laid flat": The core of this utility model lies in the limiting component and its internal anti-reverse ball forming a balancing counterweight assembly. When the outer cap is removed and the bottle is placed horizontally, this assembly generates a balancing torque like a "ballast stone" or a "seesaw," constantly pressing down on the valve body to keep it balanced and maintain a closed state. This fundamentally eliminates the serious defect of unscrupulous individuals being able to backflow by simply laying the bottle flat.

[0024] 2. Preferably, this utility model has a second outlet hole on the spout. The second outlet hole prevents tools such as thin wires from finding a straight path to pass through, thus forming the first line of defense against hacking.

[0025] 3. Balancing anti-counterfeiting strength with smooth pouring: The upper anti-reverse ball is controlled by a "short limiting component" (located in the upper cavity), while the lower anti-reverse ball is controlled by a "guide rib" (located in the lower cavity), avoiding the problem of uneven pouring caused by the "long cylindrical" cover. At the same time, it ensures that both anti-reverse balls can accurately reset and seal, achieving a perfect balance between anti-counterfeiting performance and user experience.

[0045] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described clearly and completely below with reference to the accompanying drawings. Obviously, the specific details described below are only a part of the embodiments of this utility model, and this utility model can be implemented in many other embodiments different from those described herein. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0046] In this document, when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intervening element. When 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. The directional terms such as "front," "back," "up," and "down" are defined based on the location of the components in the accompanying drawings and their relative positions, and are merely for clarity and convenience in expressing the technical solution. It should be understood that the use of these directional terms should not limit the scope of protection claimed by this utility model.

[0047] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0048] See Figure 1 In one embodiment of this utility model, the anti-backflow and anti-counterfeiting bottle cap is installed on the bottle mouth. The bottle cap includes an inner plug 10, at least one check ball 20, and a one-way valve 30.

[0049] like Figure 2As shown, the one-way valve 30 includes a valve body 31 and a limiting member 32. The valve body 31 is used to engage with the opening edge of the inner plug 10 when the one-way valve 30 is in the closed position to achieve a sealing function. The limiting member 32 is fixedly connected to the valve body 31, for example, integrally formed, and extends downward into the cavity of the inner plug 10, and at least partially covers the at least one check ball 20.

[0050] In a preferred embodiment, such as Figure 2 As shown, the limiting member 32 is cylindrical, forming a "cylindrical cover". The limiting member 32 and the check ball 20 contained inside constitute a balancing counterweight assembly, which acts as a "ballast" or "seesaw" for balance. When the outer cap of the bottle is removed and the bottle is placed horizontally, the "pot lid" valve 30 in the prior art will "fall down" on its own. However, in this utility model, the weight and structure of the limiting member 32 and the internal check ball 20 effectively manage the center of gravity of the one-way valve 30. The balancing torque it generates will always press against the sealing side of the valve body 31, keeping it balanced and tightly pressed against the opening of the inner plug 10, keeping it in a closed state, thereby preventing it from opening on its own.

[0051] In one embodiment, such as Figure 2 As shown, in order to optimize the smoothness of pouring wine without sacrificing anti-counterfeiting performance, multiple sieve holes 32a can be provided on the side wall of the limiting member 32, i.e., the cylindrical protective cover. The aperture of these sieve holes 32a is designed to be small enough (e.g., 1 mm) to prevent tools from passing through, but to allow the wine to flow smoothly when pouring.

[0052] If the limiting member 32 is designed to be too long, such as a "long cylinder," although the anti-counterfeiting performance is good, it may affect the smoothness of pouring wine. Therefore, in a preferred embodiment of this utility model, a clever "relay" solution is adopted. In this solution, the cavity of the inner plug 10 is designed as two regions with different inner diameters: an upper cavity 11 with a larger inner diameter and a lower cavity 12 with a smaller inner diameter. Two anti-reverse balls 20 are provided in the cavity, namely an upper anti-reverse ball 21 and a lower anti-reverse ball 22. The limiting member 32 is correspondingly designed as a "short protective cover," with its lower end only extending into the upper cavity 11. Its main function is to cover and restrict the radial movement of the upper anti-reverse ball 21, and to achieve the above-mentioned "anti-tool" and "anti-flat-laying" functions.

[0053] To control the lower check ball 22, multiple guide ribs 101 are provided on the inner wall of the lower cavity 12 of the inner plug 10. Preferably, as shown below... Figure 3As shown, there are 8 guide ribs. These 8 guide ribs 101 together define a circular "guide track" within the lower cavity 12. The inner diameter of this track precisely matches the outer diameter of the lower anti-reverse ball 22. This ensures that the lower anti-reverse ball 22 is always confined within this track when moving up and down, and will not experience radial displacement or "deviation".

[0054] This "relay" solution of "short limiting tube upper bead + 8 guide rib tube lower bead" not only ensures the anti-counterfeiting performance of the upper structure, but also ensures the accurate sealing of the bottom anti-reverse ball through the guide ribs. At the same time, the optimized short protective cover structure also ensures the smoothness of pouring wine.

[0055] like Figure 4 As shown, this utility model also includes a wine outlet 40 disposed above the one-way valve 30. The top surface of the wine outlet 40 has a plurality of wine outlet holes. These wine outlet holes are preferably designed such that at least one first wine outlet hole 41 (e.g., for air reflux) is disposed in the center, and a plurality of second wine outlet holes 42 (for dispensing wine) are arranged around it.

[0056] In a preferred embodiment, the second wine outlet 42 is configured as two rings (e.g., an inner ring and an outer ring), and the wine outlets of the inner ring and the outer ring are staggered.

[0057] Finally, this utility model also provides a wine bottle (not shown in the figure), characterized in that it is fitted with any of the anti-backflow and anti-counterfeiting bottle caps described above.

[0058] Those skilled in the art will understand that the structure of the limiting member 32 is not limited to a continuous cylinder. In another alternative embodiment, the limiting member 32 can be designed as a cage-like structure. Specifically, the cage-like structure can consist of multiple axially extending columns or rods, the lower ends of which can be connected to an annular ring or extend independently downward from the valve body 31. These columns or rods also form a "covering" and radial restriction on the check ball 20, preventing its displacement, and also serve as a "balanced counterweight" when the bottle is laid flat.

[0059] In summary, this utility model solves two major industry problems—"tool prying" and "flat pouring"—through a combination of "limiting component balancing weight" and "multi-layer misaligned maze" design. Furthermore, the "relay solution" balances anti-counterfeiting performance with smooth pouring, making it highly practical.

[0060] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
