Abstract
Description
Technical Field
[0001] This utility model relates to the field of bottle opener technology, and in particular to a bottle opener. Background Technology
[0002] Beverages with cork stoppers, such as wine and rice wine, refer to bottled liquid foods that use cork as the sealing material at the bottle opening. In terms of categories, wine (including red wine, white wine, and sparkling wine) is the most typical example. Its cork stoppers are mostly made from the bark of cork oak trees in the Mediterranean region, possessing excellent elasticity and breathability. The elasticity ensures the stopper fits tightly against the bottle opening, preventing the ingress of outside air and moisture; the breathability allows a small amount of air to slowly enter the bottle, helping the wine mature gradually during storage and develop a richer flavor profile. Some mid-to-high-end rice wine products (such as aged rice wine and handcrafted rice wine) also use cork stoppers. This is because these types of rice wine require long-term storage to improve their flavor. The sealing and stability of cork avoids the potential for odor contamination or seal failure that can occur with traditional plastic stoppers or metal caps. Cork stoppers must be firmly fixed to the bottle opening and cannot be pulled out by hand; a special corkscrew is required to open them.
[0003] A bottle opener suitable for cork-corked beverages such as wine and rice wine is a tool specifically designed to break the seal between the cork and the bottle neck and remove the cork from the bottle. Because cork is soft yet has a certain degree of toughness and there is considerable friction between it and the inner wall of the bottle neck, the bottle opener must have two core functions: first, "drilling and fixing," which involves screwing a threaded part (such as a drill bit) into the cork to establish a connection point between the tool and the cork; second, "pulling out by force," which uses levers, pulling force, or clamping structures to overcome the friction between the cork and the bottle neck and remove the cork completely.
[0004] Existing bottle openers mostly rely on a single auger bit structure. The cork is removed by screwing the bit into it and pulling it out. However, due to the limited contact area between the bit and the cork, the gripping force is insufficient. When dealing with cork corks that are tight or brittle, the cork is prone to breakage or falling off. Broken corks left at the bottle opening not only affect the use of the beverage but also require additional tools for cleaning, greatly reducing the efficiency of opening bottles. Furthermore, traditional bottle openers lack operational safety. After removing the cork, users need to directly touch the cork with their hands and pull it off the bit. However, the tip of the bit is sharp, and the edges of the grippers in some bottle openers are sharp, making it easy for hands to be cut by sharp parts during contact. Therefore, a new bottle opener is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above deficiencies, this utility model provides a bottle opener, which aims to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A bottle opener includes a bottle opener body, wherein the interior of the bottle opener body is provided with a bottle opening mechanism for drilling into and grabbing the bottle stopper, and the bottom of the bottle opener body is provided with a protective mechanism for safely removing the bottle stopper.
[0008] The bottle opening mechanism includes a cross plate, which is fixedly connected to the top inner wall of the bottle opener body. A rivet is installed in the center of the cross plate, and a central rod is threadedly connected to the rivet. An opening is provided on both the left and right sides of the bottom of the central rod. A fixed shaft is fixedly connected inside the opening. An expandable blade is rotatably connected to the outer wall of the fixed shaft. A drill bit is fixedly connected to the bottom end of the central rod.
[0009] As a further description of the above technical solution:
[0010] Both blades have rounded outer end faces, the outer wall of the blade is in contact with the inner wall of the opening, and the blade is in an unfolded state when not subjected to external force.
[0011] As a further description of the above technical solution:
[0012] The protective mechanism includes a cover, the inner side of which is threaded to the bottom outer side of the bottle opener body. Multiple rivet parts are installed circumferentially inside the cover. A vertical rod is installed on the inner thread of the rivet parts. An opening is provided on the top of the vertical rod near the center rod. A fixed shaft is fixedly connected inside the opening. An unfoldable pressure plate is rotatably connected to the outer wall of the fixed shaft.
[0013] As a further description of the above technical solution:
[0014] The drill bit has a continuous thread structure on its outside, and the outer surfaces of the bottle opener body and the cap body are both provided with anti-slip textures.
[0015] As a further description of the above technical solution:
[0016] The outer wall of the pressure plate is in contact with the inner wall of the second opening. The pressure plate is naturally tilted downward when not subjected to external force. The cover is hollow in shape.
[0017] As a further description of the above technical solution:
[0018] Mounting holes are provided in the middle of the cross plate and at the bottom of the cover, respectively for mounting the first riveting component and the second riveting component;
[0019] As a further description of the above technical solution:
[0020] During the process of the drill bit being screwed into the bottle stopper, a portion of the blade near the fixed shaft retracts into the opening, while the remaining portion extends out of the opening. During the process of removing the bottle stopper, the blade unfolds outward under the frictional force of the bottle stopper, with the maximum unfolding angle perpendicular to the central rod at 90°.
[0021] As a further description of the above technical solution:
[0022] During the process of removing the bottle stopper, multiple pressure plates contact the top of the bottle stopper and unfold, with the maximum unfolding angle perpendicular to the upright rod at 90°. The length of the upright rod is greater than that of a conventional bottle stopper.
[0023] This utility model has the following beneficial effects:
[0024] 1. In this utility model, the tapered drill bit at the bottom of the central rod has a continuous thread structure, which can easily screw into the cork stopper. When the blade is not subjected to external force, it is in an unfolded state. During the process of screwing into the stopper, the squeezed part retracts into the opening, and the remaining part keeps in contact with the stopper to avoid slippage. When the drill bit has drilled into the stopper to a certain depth, when the central rod is pulled in the opposite direction to remove the stopper, the blade unfolds outward under the action of friction, which greatly increases the contact area and gripping force with the stopper, improves the problem of insufficient gripping force, easy breakage or fall off of the stopper, and improves the efficiency and success rate of opening bottles.
[0025] 2. In this utility model, when the bottle stopper is pulled out, rotating the cap can drive the upright rod to move downward. After the pressure plate contacts the top of the bottle stopper, it gradually unfolds. At this time, the anti-slip protrusion at the end of the pressure plate increases the friction between it and the bottle stopper, and at the same time applies a uniform downward rotating force to the bottle stopper, causing the bottle stopper to rotate in the opposite direction to the direction in which the drill bit is screwed in, making it easier to remove it from the drill bit. The whole process does not require direct contact with the bottle stopper by hand, completely avoiding the risk of hand being cut by the sharp end of the drill bit or the edge of the blade. Compared with the operation of traditional bottle openers that require manual removal of the stopper, the safety is significantly improved.
[0026] 3. In this utility model, the middle part of the cross plate and the bottom of the cover are provided with matching mounting holes, which are used to install riveting part one and riveting part two, respectively. Both types of riveting parts are cylindrical structures with internal threads on the inner wall. They can be quickly fixed in the mounting holes by riveting process. Afterwards, the assembly can be completed by connecting the center rod and the upright rod to the riveting parts by thread. There is no need for complicated welding or custom processing, which reduces the production difficulty, shortens the production cycle, and facilitates mass production. Attached Figure Description

[0035] 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.
[0036] Reference Figure 2 , Figure 3 and Figure 4 The present invention provides an embodiment of a bottle opener, including a bottle opener body 1, which is a hollow cylindrical design. The whole body is made of high-strength food-grade stainless steel, which not only ensures the structural strength to withstand the torque when opening the bottle, but also meets the food contact safety standards. At the same time, it has good corrosion resistance and extends service life. The bottle opener body 1 is provided with a bottle opening mechanism for drilling into and grabbing the bottle stopper, and the bottom of the bottle opener body 1 is provided with a protective mechanism for safely removing the bottle stopper.
[0037] The bottle opening mechanism includes a cross plate 2, which is externally fixedly connected to the top inner wall of the bottle opener body 1. The outer edge of the cross plate 2 is fixedly connected to the bottle opener body 1 by welding or integral molding. A rivet 3 is installed in the center of the cross plate 2, and a central rod 4 is internally threaded to the rivet 3. The four ends of the cross plate 2 are respectively connected to the inner wall of the bottle opener body 1, which can evenly distribute the force generated during bottle opening, avoid excessive local force leading to deformation of the body, and provide guidance for the axial movement of the central rod 4. Openings 6 are provided on the left and right sides of the bottom of the central rod 4, and a fixed shaft 7 is fixedly connected inside the opening 6. The outer wall of the fixed shaft 7 rotates. The device is connected to deployable blades 8. The outer ends of both blades 8 are rounded to prevent scratching the bottle stopper or generating excessive local pressure when in contact with it. The outer wall of the blade 8 contacts the inner wall of the opening 6. The size of the opening 6 matches the thickness of the blade 8, providing space for the blade 8 to retract and unfold. The blade 8 is in the unfolded state when not under external force. The two openings 6 are symmetrically distributed to ensure that the blades 8 on both sides can move synchronously and ensure that the gripping force on the bottle stopper is evenly distributed. The bottom end of the central rod 4 is fixedly connected to a drill bit 5. The drill bit 5 has a continuous thread structure on the outside. The drill bit 5 has a conical structure, and the continuous spiral thread on the outside makes it easy to screw into cork bottle stoppers.
[0038] During the process of the drill bit 5 being screwed into the bottle stopper, the blade 8 retracts into the opening 6 near the fixed shaft 7, while the remaining part extends out of the opening 6; during the process of removing the bottle stopper, the blade 8 unfolds outward under the friction force of the bottle stopper, and the maximum unfolding angle is perpendicular to the center rod 4 at 90°. By increasing the contact area and friction force with the bottle stopper, the blade 8 can stably grip the bottle stopper.
[0039] Reference Figure 3 , Figure 5 and Figure 6The protective mechanism includes a cover 9, the inner side of which is threaded to the bottom outer side of the bottle opener body 1. The cover 9 is hollow, allowing the bottle stopper to pass through. The cover 9 is made of the same food-grade stainless steel as the bottle opener body 1, ensuring structural strength while facilitating cleaning and maintenance. Multiple rivet parts 10 are installed circumferentially inside the cover 9. A vertical rod 11 is threaded inside each rivet part 10. The length of the vertical rod 11 is greater than that of a conventional bottle stopper, ensuring sufficient travel to completely push the bottle stopper off the drill bit 5. An opening 12 is provided on the top of the vertical rod 11 near the center rod 4. A fixed shaft 13 is fixedly connected inside the opening 12. The outer wall is rotatably connected to an expandable pressure plate 14. The outer wall of the pressure plate 14 contacts the inner wall of the second opening 12. The size of the second opening 12 matches the thickness and length of the pressure plate 14, providing space for the rotation of the pressure plate 14. The second fixed shaft 13 is the rotation axis of the pressure plate 14. The pressure plate 14 is in a natural downward tilting state when not subjected to external force. The bottom of the pressure plate 14 is provided with anti-slip protrusions. During the process of removing the bottle stopper, multiple pressure plates 14 contact the top of the bottle stopper and unfold. The maximum unfolding angle is perpendicular to the upright rod 11 at 90°. The anti-slip protrusions increase the friction between the pressure plate and the bottle stopper. At the same time, a uniform downward rotating force is applied to the bottle stopper, causing the bottle stopper to rotate in the opposite direction to the direction in which the drill bit 5 is screwed in, making it easier to remove it from the drill bit 5.
[0040] Reference Figure 1 and Figure 2 The outer surfaces of both the bottle opener body 1 and the cap 9 are provided with anti-slip textures. The anti-slip textures adopt a continuous concave-convex stripe design, which can increase the friction between the hand and the body, ensuring that it is not easy to slip during rotation operation, improving grip stability, and providing a certain degree of aesthetics. The middle part of the cross plate 2 and the bottom of the cap 9 are provided with mounting holes for installing riveting parts 1 3 and 2 10, respectively. Both riveting parts 1 3 and 2 10 are cylindrical structures, which are fixedly installed in the mounting holes in the center of the cross plate 2 and the bottom of the cap 9 by riveting process. Their inner walls are machined with internal threads to match the external threads of the center rod 4 and the upright rod 11. The setting of mounting holes and riveting parts facilitates the manufacturing of the bottle opener.
[0041] Working principle: When in use, align the bottle opener with the bottle stopper. Rotate the bottle opener body 1 to rotate the center rod 4, causing the drill bit 5 with a continuous thread structure to screw into the bottle stopper. During the screwing process, the blade 8, which was originally in an extended state, is squeezed by the bottle stopper. The part near the fixed shaft 7 retracts into the opening 6, while the remaining part remains extended and in contact with the bottle stopper. When the drill bit 5 has drilled into the bottle stopper to a certain depth, pull the center rod 4 in the opposite direction to start removing the bottle stopper. If the bottle stopper cannot be pulled out, continue to rotate downwards and try to pull it out again. If the bottle stopper still cannot be pulled out, continue the above actions until the drill bit 5 has completely drilled into the bottle stopper. Then pull the bottle stopper out. At this time, the blade 8 unfolds outwards under the friction of the bottle stopper. The close contact between the blade 8 and the bottle stopper increases the gripping force, ensuring that the bottle stopper is stably pulled out of the bottle mouth.
[0042] After the bottle stopper is pulled out, the cap 9, which is threadedly connected to the bottle opener body 1, is rotated, causing the upright rod 11 to move upward. During this process, the pressure plate 14, which was originally tilted downward, contacts the top of the bottle stopper and gradually unfolds until it is perpendicular to the upright rod 11 at 90°. The anti-slip protrusion at the end of the pressure plate 14 increases the friction between it and the bottle stopper. Continuing to rotate the cap 9 allows the pressure plate 14 to apply a uniform downward rotating force to the bottle stopper, causing the bottle stopper to rotate in the opposite direction to the direction in which the drill bit 5 is screwed in. In addition, the length of the upright rod 11 is greater than the length of the bottle stopper, which makes it easier to detach the bottle stopper from the drill bit 5. The whole process does not require direct contact with the bottle stopper by hand, avoiding the risk of hand injury from sharp parts such as the drill bit 5 and the blade 8.
[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
