Description

TECHNICAL FIELD

[0001] The utility model relates to wine bottle cap technical field, specifically is a wine bottle cap. BACKGROUND

[0002] For wine products, the sealing performance of the bottle cap is particularly important. The alcohol and other components in the wine are prone to volatilization, and good bottle cap sealing can reduce alcohol volatilization, maintain the aroma and taste of the wine, and prevent the wine from deteriorating. The twist-off bottle cap is opened by twisting and breaking, and once opened, the anti-theft ring or safety ring will break and cannot be restored to its original state, which can clearly show whether the bottle cap has been opened, and plays a good anti-theft and anti-tampering role, allowing consumers to intuitively determine whether the wine is the original unopened product.

[0003] For the elderly, children or people with weak hand strength, the twist-off bottle cap may be difficult to open. It requires a lot of effort to twist the bottle cap, which may cause hand pain or even injury. Moreover, if the design of the twist-off bottle cap is not reasonable, it may also occur that multiple attempts are required to successfully twist off, which is inconvenient for the user. Once the twist-off bottle cap is twisted off, it cannot be resealed as completely as a normal bottle cap. If the wine in the bottle is not finished, the remaining wine is difficult to seal well, which can easily cause the wine to deteriorate and the aroma to dissipate, affecting the quality of the wine. Therefore, we propose a wine bottle cap. SUMMARY

[0004] The utility model aims at providing a wine bottle cap, which has the advantages of ensuring that the safety device is not easily damaged during transportation, facilitating opening, requiring less effort to open, and being able to continue sealing after opening, solving the problems of inconvenient opening and inability to continue sealing after opening of the existing twist-off bottle cap.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a wine bottle cap, comprising an upper cap and a lower cap, the lower cap is fixedly installed on the bottle mouth, and a threaded cap is fixed on the upper cap and is threadedly connected with the bottle mouth through the threaded cap.

[0006] An upper safety device section is provided on the upper cap, and a lower safety device section connected with the upper safety device section is provided on the lower cap, the safety device is a plastic part, divided into an upper safety device section and a lower safety device section, and a punch cracking line is provided between the upper safety device section and the lower safety device section; the punch cracking line is a weakened line on the safety device, the purpose is to make the safety device twist off along this line when the bottle cap is opened, and the punch cracking line can reduce the required torque for opening based on the principle of stress concentration.

[0007] The lower cover is provided with a limiting protrusion, and the upper cover is provided with a limiting ring that matches the limiting protrusion. After the limiting protrusion is inserted into the groove of the limiting ring, it is used to restrict the upper cover from rotating relative to the lower cover, so as to prevent the bottle cap from rotating and the safety device from breaking due to collision or other reasons during transportation.

[0008] The top cover is provided with a sliding groove, and the limiting ring can slide longitudinally along the sliding groove. When the limiting ring slides upward, the limiting protrusion disengages from the groove of the limiting ring, thus removing the restriction on the rotation of the top cover and making it convenient for the user to open the bottle cap.

[0009] Preferably, the lower cover is equipped with an anti-counterfeiting mechanism. The lower section of the safety device is inserted into the housing of the anti-counterfeiting mechanism. The lower section of the safety device is connected to a metal component. A magnetic element is installed inside the housing. This magnetic element is used to magnetically pull the lower section of the safety device and the metal component into the housing after the safety device is disconnected. Once the lower section of the safety device is pulled into the housing, it cannot be removed, thus providing excellent anti-theft and anti-tampering protection and preventing criminals from restoring the safety device.

[0010] Preferably, the housing contains a roll with an anti-counterfeiting layer wound on it. The anti-counterfeiting layer bypasses a guide rod inside the housing and connects to a metal component. The front of the anti-counterfeiting layer faces the outside of the lower cap, and an observation window is provided on the lower cap corresponding to the anti-counterfeiting layer. While the magnetic element draws the lower section of the safety component and the metal component into the housing, the metal component pulls the anti-counterfeiting layer out of the roll. When the bottle cap is closed, the observation window on the outward-facing side of the anti-counterfeiting layer displays sealing information. When the bottle cap is opened, pulling the roll rotates the bottle, so that the information indicating that the bottle has been opened is visible under the observation window, allowing consumers to intuitively determine whether the wine is an original, unopened product.

[0011] Preferably, a fluorescent plate is disposed inside the housing and on the back of the anti-counterfeiting layer. The fluorescent plate serves as a background for observing the anti-counterfeiting layer through the observation window. The fluorescent plate, acting as a light source such as visible light shining through the observation window, excites the fluorescent material, thereby making the anti-counterfeiting layer more noticeable.

[0012] Preferably, the lower cap is fixed to the bottle neck by a fastener. The fastener ensures that the lower cap does not move as the upper cap rotates.

[0013] Preferably, the anti-counterfeiting layer has two different markings indicating a sealed state and an open state, and the anti-counterfeiting layer is made of a light-transmitting material. The transparent material of the anti-counterfeiting layer allows light from the fluorescent board to pass through, thus making it more noticeable.

[0014] Preferably, the top cover is fitted with decorative elements. These decorative elements serve both an aesthetic purpose and allow for the printing of the product's brand, thus acting as an identifier.

[0015] Preferably, the limiting ring and the limiting protrusion are fixed together by wrapping with a plastic layer or by magnetic attraction. Wrapping with a plastic layer prevents the limiting ring from sliding up and down during transportation, ensuring stable fixation to the upper and lower covers. Magnetic attraction uses a magnetic material to attract the limiting ring and the limiting protrusion, preventing slippage.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention utilizes a stamped crack line between the upper and lower sections of the safety cap, allowing it to be easily broken with minimal force. The safety cap then falls into the anti-counterfeiting mechanism's housing and cannot be removed, effectively preventing theft and tampering. Consumers can directly verify the authenticity of the bottle. To prevent breakage during transport, a limiting ring and a limiting protrusion secure the upper and lower caps. Even in the event of a collision or twisting of the upper cap, the bottle cap cannot be opened, and the safety cap will not break. The limiting ring and protrusion are sealed with a plastic layer. To open the bottle cap, simply peel off the plastic layer, slide the limiting ring upwards, and gently rotate the upper cap to break the safety cap and open the bottle cap without damaging the threaded cap or bottle neck. The bottle can be resealed after opening. This solves the problems of inconvenient opening and failure to reseal existing twist-off bottle caps. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figure 1 and 2 As shown, a bottle cap includes an upper cap 1 and a lower cap 2. The lower cap 2 is fixedly installed on the bottle mouth 3, and a threaded cap 11 is fixed on the upper cap 1 and is threadedly connected to the bottle mouth 3 through the threaded cap 11.

[0030] The upper cover 1 is provided with an upper section 12 of the safety element, and the lower cover 2 is provided with a lower section 21 of the safety element connected to the upper section 12 of the safety element. The safety element is a plastic part, which is divided into an upper section 12 of the safety element and a lower section 21 of the safety element. A stamping crack line is provided between the upper section 12 of the safety element and the lower section 21 of the safety element. The stamping crack line is a weakening line on the safety element. Its purpose is to enable the safety element to break along this line when the bottle cap is opened. The stamping crack line is based on the principle of stress concentration and can reduce the torque required to open.

[0031] The lower cover 2 is provided with a limiting protrusion 23, and the upper cover 1 is provided with a limiting ring 13 that matches the limiting protrusion 23. After the limiting protrusion 23 is inserted into the groove of the limiting ring 13, it is used to limit the upper cover 1 from rotating relative to the lower cover 2; so as to prevent the bottle cap from rotating and the safety device from breaking due to collision or other reasons during transportation.

[0032] The top cover 1 is provided with a sliding groove 14, and the limiting ring 13 can slide longitudinally along the sliding groove 14. When the limiting ring 13 slides upward, the limiting protrusion 23 disengages from the groove of the limiting ring 13, thus removing the restriction on the rotation of the top cover 1, making it convenient for users to open the bottle cap.

[0033] The limiting ring 13 and the limiting protrusion 23 are fixed together by a plastic layer or by magnetic attraction. The plastic layer prevents the limiting ring 13 from sliding up and down during transportation, ensuring its stable fixation to the upper cover 1 and the lower cover 2. Magnetic attraction uses magnets to attract the limiting ring 13 and the limiting protrusion 23, preventing slippage.

[0034] like Figure 1 and 2 As shown, the lower cover 2 is fixed to the bottle mouth 3 by a fastener 24. The fastener 24 ensures that the lower cover 2 does not move as the upper cover 1 rotates.

[0035] The lower cover 2 is equipped with an anti-counterfeiting mechanism 22, such as Figure 3 and 4 As shown, the lower segment 21 of the fuse is inserted into the housing 221 of the anti-counterfeiting mechanism 22. The lower segment 21 is connected to a metal component 211. A magnetic element 222 is installed inside the housing 221. The magnetic element 222 is used to magnetically draw the lower segment 21 and the metal component 211 into the housing 221 after the fuse is disengaged. Once the lower segment 21 is drawn into the housing 221, it cannot be removed, thus providing excellent anti-theft and anti-tampering protection, preventing criminals from restoring the fuse and reselling it.

[0036] A drum 223 is provided inside the housing 221, such as Figure 5 As shown, an anti-counterfeiting layer 224 is wound on the roll 223. The anti-counterfeiting layer 224 bypasses the guide rod 225 inside the housing 221 and is connected to the metal part 211. The guide rod 225 can change the direction of movement of the anti-counterfeiting layer 224. When the metal part 211 moves downward, it pulls the anti-counterfeiting layer 224 upward, pulling out the anti-counterfeiting layer 224 with the opened information from the roll 223. The front of the anti-counterfeiting layer 224 faces the outside of the lower cover 2, and an observation window 2 is provided on the lower cover 2 corresponding to the anti-counterfeiting layer 224. 5. While the magnetic element 222 draws the lower section 21 of the safety device and the metal part 211 into the housing 221, the metal part 211 is used to pull the anti-counterfeiting layer 224 out of the roll 223. When the bottle cap is not opened, the observation window 25 on the outward side of the anti-counterfeiting layer 224 displays the sealing information. When the bottle cap is opened, the roll 223 is pulled to rotate, so that the information written on the anti-counterfeiting layer 224 indicating that it has been opened is under the observation window 25, allowing consumers to intuitively judge whether the wine is an original unopened product.

[0037] like Figure 3 and 4 As shown, a fluorescent plate 226 is disposed inside the housing 221 and on the back of the anti-counterfeiting layer 224. The fluorescent plate 226 serves as a background for observing the anti-counterfeiting layer 224 through the observation window 25. The fluorescent plate 226 acts as a light source, such as visible light, shining through the observation window 25 to excite the fluorescent material, thereby making the anti-counterfeiting layer 224 more conspicuous.

[0038] like Figures 6-8 As shown, the anti-counterfeiting layer 224 has two different markings indicating a sealed state and an open state, and the anti-counterfeiting layer 224 is made of a light-transmitting material. The transparent material of the anti-counterfeiting layer 224 allows light from the fluorescent board 226 to pass through easily, thus serving a conspicuous purpose.

[0039] like Figure 9 As shown, a decorative element 4 is installed on the top cover 1. By setting the decorative element 4, it serves two purposes: aesthetics and branding of the product, thus acting as an identifier.

[0040] In use, a stamped crack line is set between the upper section 12 and the lower section 21 of the safety device, allowing it to be easily broken with minimal force. This causes the safety device to fall into the housing 221 of the anti-counterfeiting mechanism 22, making it impossible to remove. This provides excellent anti-theft and anti-tampering protection, allowing consumers to directly determine whether the wine is an original, unopened product. Figure 6 As shown, to prevent the safety device from breaking during transportation, a limiting ring 13 and a limiting protrusion 23 are used to fix the positions of the upper cap 1 and the lower cap 2. Even if there is a collision or twisting of the upper cap 1, the bottle cap cannot be opened, and the safety device will not break. The limiting ring 13 and the limiting protrusion 23 are sealed with a plastic layer. Figure 7 As shown, when it is necessary to open the bottle cap, peel off the plastic layer, slide the limiting ring 13 upwards, and gently rotate the top cover 1 to break the safety device, open the bottle cap, and avoid damaging the threaded cap 11 and the bottle mouth 3. After opening, it can continue to seal. Figure 8 As shown, after the bottle cap is opened, the safety device is disconnected. The lower section 21 of the safety device falls into the housing 221 of the anti-counterfeiting mechanism 22 under the action of gravity and magnetic element 222. During the downward movement of the lower section 21 of the safety device, the anti-counterfeiting layer 224 with the information that it has been opened is pulled out from the roll 223, allowing consumers to use the observation window 25 to intuitively determine whether the wine is an original unopened product.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
