Description

Technical Field

[0001] This utility model relates to the field of beer bottle cap technology, specifically to a combination beer bottle cap. Background Technology

[0002] Most beer bottle caps in the current technology are screw-on structures. This type of beer bottle cap has the following drawbacks in use: the larger the cap, the greater the force required to generate enough torque to overcome the friction and sealing force between the cap and the bottle mouth. The more effort is required to screw on the cap, especially under the pressure of the gas inside the bottle. Under high pressure, the threads of large-diameter caps will be subjected to air pressure force, making them even more difficult to screw on.

[0003] Furthermore, in the beer bottle manufacturing process, if a large-capacity beer bottle is to be produced, a large-diameter design must be used; otherwise, the required weight standard for the bottle cannot be met. A small-diameter design cannot meet product requirements in casting or blow molding processes, and it is impossible to produce large-capacity beer bottles with specific weight requirements.

[0004] Therefore, existing technologies need further development. Utility Model Content

[0005] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and provide a beer bottle cap assembly to solve the technical problem that large-diameter beer bottle caps are difficult to screw on in related technologies.

[0006] To achieve the above technical objectives, the present invention adopts the following technical solution: a beer bottle cap assembly is provided, comprising: a first cap body, the first cap body being detachably mounted on the beer bottle body; a first bottle mouth, the first bottle mouth being disposed on the first cap body, the first bottle mouth being provided with a first external thread, the diameter of the first bottle mouth being smaller than the diameter of the first cap body; and a second cap body, the second cap body including an accommodating space disposed inside the second cap body, a connecting component being disposed within the accommodating space, the inner side of the connecting component being provided with a first internal thread corresponding to the first external thread.

[0007] Furthermore, the connecting component includes: a connecting portion, which protrudes into the accommodating space and extends axially along the second cover, and is hollow inside; and a third cover, which is detachably installed inside the connecting portion, and has a first internal thread on its inner side.

[0008] Furthermore, a limiting tooth is provided on the second inner wall of the connecting part, the limiting tooth extends along the axial direction of the connecting part, and a limiting groove corresponding to the limiting tooth is provided on the outer surface of the third cover, the limiting groove abuts against the limiting tooth, wherein the limiting tooth includes a plurality of limiting teeth, and a plurality of limiting grooves are provided accordingly.

[0009] Furthermore, the connecting component includes a third cover, which is fixedly connected to the second cover, and the inner side of the third cover is provided with a first internal thread.

[0010] Furthermore, the first cap includes a first inner wall, which houses the mouth of a beer bottle. A second internal thread is provided on the first inner wall, which is threadedly connected to the mouth of the beer bottle. The diameter of the first mouth is smaller than the inner diameter of the first inner wall.

[0011] Furthermore, the first cap includes an annular protrusion disposed inside the first cap, the annular protrusion extending along the axial direction of the first cap, the interior of the annular protrusion being hollow, the interior of the annular protrusion communicating with the interior of the first bottle neck, the annular protrusion being spaced apart from the first inner wall, and at least a portion of the beer bottle neck being accommodated between the annular protrusion and the first inner wall.

[0012] Furthermore, a recessed groove is formed on the side of the annular protrusion near the first inner wall, and the groove contains the mouth of a beer bottle.

[0013] Furthermore, the first cap includes an installation platform located on the side of the first cap away from the beer bottle body, and a first bottle opening is formed on the installation platform, the first bottle opening protruding from the installation platform.

[0014] Furthermore, the second cover includes an anti-slip block, which protrudes from the outer peripheral surface of the second cover. The anti-slip block includes multiple blocks, which are arranged in a circumferential array around the axis of the second cover.

[0015] Beneficial effects:

[0016] 1. By improving the traditional single cap structure to a double or multi-layer cap combination structure, the smaller diameter design of the first bottle opening reduces the force required for twisting, significantly reduces the difficulty of twisting, and improves the ease of operation. Under the premise of meeting the weight standard and production process requirements of beer bottles, the difficulty of twisting is greatly reduced, the user experience is improved, and the technical problem of large-diameter beer bottle caps being difficult to twist in related technologies is solved.

[0017] 2. By setting a connecting part for installing the third cap, specifically, the outer diameter of the second cap is larger than that of the third cap. The second cap with a larger outer diameter is used as a tool to screw on the third cap with a smaller outer diameter, which increases the contact area between the user and the bottle cap, making it easier for the user to screw on the third cap with a relatively smaller diameter. In actual operation, the user screws on the third cap with a smaller outer diameter rather than the larger diameter cap. The third cap with a smaller outer diameter is less affected by air pressure because of its smaller screw opening, so it is easier to unscrew.

[0018] 3. Based on the third cap, a second cap with a larger diameter is adopted. This not only facilitates the easier and less strenuous screwing of the "small bottle cap" (third cap), but also allows the second cap to serve as a "decorative cap." The diameter of the second cap can be adapted as closely as possible to the diameter of the first cap and the beer bottle body. For example, the outer diameter of the second cap and the first cap can be made to be the same, thereby making the overall appearance of the beer bottle more harmonious and beautiful, and playing a decorative role.

[0025] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0026] According to an embodiment of this utility model, a beer bottle cap combination is provided; please refer to [link / reference]. Figures 1 to 4The system includes: a first cap 1, which is detachably mounted on the body 10 of a beer bottle; a first bottle neck 2, which is disposed on the first cap 1, the diameter of the first bottle neck 2 being smaller than the diameter of the first cap 1, and the first bottle neck 2 having a first external thread; and a second cap 3, which includes an accommodating space 30 disposed inside the second cap 3, and a connecting component 4 disposed within the accommodating space 30, the inner side of the connecting component 4 having a first internal thread corresponding to the first external thread.

[0027] The first cap 1 has a first bottle neck 2, the diameter of which is smaller than the diameter of the first cap 1, and a first external thread is provided on its outer side. The design of the first external thread allows the first bottle neck 2 to fit tightly with the connecting part 4 in the second cap 3. By reducing the diameter of the first bottle neck 2, which is smaller than the diameter of the first cap 1, the first cap adopts a large-diameter design, thus meeting the weight standards and production process requirements of beer bottles. The small-diameter design of the first bottle neck 2 makes it easier to unscrew, reducing the difficulty of screwing on the second cap 3.

[0028] The second cap 3 has an internal accommodating space 30, within which a connecting component 4 is fixed. The inner side of the connecting component 4 has a first internal thread corresponding to the first external thread. This matching design of the internal and external threads ensures a reliable connection between the first cap 1 and the second cap 3. When the user rotates the second cap 3, the first internal thread interacts with the first external thread, allowing the second cap 3 to move smoothly along the axial direction of the first bottle opening 2. Simultaneously, the first bottle opening 2 employs a small-diameter design, making the screw-on opening action easy.

[0029] By improving the traditional single cap structure into a double or multi-layer cap combination structure, the smaller diameter design of the first bottle opening 2 reduces the force required for twisting, significantly reduces the difficulty of twisting, and improves the ease of operation. Under the premise of meeting the weight standard and production process requirements of beer bottles, it greatly reduces the difficulty of twisting, improves the user experience, and solves the technical problem of large-diameter beer bottle caps being difficult to twist in related technologies.

[0030] In the beer bottle cap assembly of this embodiment, see... Figure 2The connecting component 4 includes: a connecting part 41, which protrudes from the accommodating space 30 and extends axially along the second cap 3, and is hollow inside; and a third cap 42, which is detachably installed in the connecting part 41, and has a first internal thread on its inner side. Thus, by providing the connecting part 41 for installing the third cap 42, specifically, the outer diameter of the second cap 3 is larger than the outer diameter of the third cap 42. Using the larger outer diameter second cap 3 as a tool to screw on the smaller outer diameter third cap 42 increases the contact area between the user and the cap, making it easier for the user to screw on the relatively smaller diameter third cap 42. In actual operation, the user screws on the smaller outer diameter third cap 42 rather than the larger diameter cap. Because the smaller outer diameter third cap 42 has a smaller thread opening, it is less affected by air pressure and therefore easier to unscrew.

[0031] Based on the third cap 42, a second cap 3 with a larger diameter is adopted. This not only facilitates the easier and less strenuous screwing of the "small bottle cap" (third cap 42), but also allows the second cap 3 to serve as a "decorative cap." The diameter of the second cap 3 can be adapted as closely as possible to the diameter of the first cap 1 and the beer bottle body. For example, the outer diameters of the second cap 3 and the first cap 1 can be made to be the same, thereby making the overall appearance of the beer bottle more harmonious and beautiful, and playing a decorative role.

[0032] The third cap 42 is detachably installed inside the connecting part 41. The second cap 3 can be pressed onto the third cap 42 and used as a decorative cap. When it is necessary to open the beer bottle, the second cap 3 can be used to screw the third cap 42.

[0033] Specifically, the connecting part 41 is fixedly connected to the second cover 3, which can be integrally formed by injection molding.

[0034] It should be noted that the diameters of the first cap 1 and the second cap 3 are both larger than that of the third cap 42. The third cap 42 adopts a small-diameter design, which makes it easier to open the beer bottle. The first cap 1 adopts a large-diameter design to meet the weight requirements of the beer bottle. The second cap 3 adopts a large-diameter design to facilitate the screwing on the third cap 42.

[0035] In the beer bottle cap assembly of this embodiment, see... Figure 2A limiting tooth 411 is provided on the second inner wall of the connecting part 41, extending axially along the connecting part 41. A limiting groove 421 corresponding to the limiting tooth 411 is provided on the outer surface of the third cover 42, abutting against the limiting tooth 411. Several limiting teeth 411 and several limiting grooves 421 are provided accordingly. By providing the limiting teeth 411 and the limiting grooves 421, relative rotation between the third cover 42 and the connecting part 41 is restricted, thereby facilitating the control of the rotation of the third cover 42 by screwing on the second cover 3, making it convenient for the user to operate.

[0036] In another embodiment of the beer bottle cap assembly, the connecting component 4 includes a third cap body 42, which is fixedly connected to the second cap body 3. The third cap body 42 has a first internal thread on its inner side. In this way, the third cap body 42 and the second cap body 3 can be integrally injection molded without the need for a limiting structure.

[0037] In the beer bottle cap assembly of this embodiment, see... Figure 2 The first cap 1 includes a first inner wall 11, which houses the neck of a beer bottle. A second internal thread is provided on the first inner wall 11, which is threadedly connected to the neck of the beer bottle. The diameter of the first neck 2 is smaller than the inner diameter of the first inner wall 11. This threaded connection between the second internal thread and the neck of the beer bottle ensures a reliable connection between the first cap 1 and the beer bottle. The smaller diameter of the first neck 2 facilitates the screwing on of the second cap 3.

[0038] In the beer bottle cap assembly of this embodiment, see... Figure 2 The first cap 1 includes an annular protrusion 12 disposed inside the first cap 1. The annular protrusion 12 extends axially along the first cap 1 and is hollow inside. The interior of the annular protrusion 12 communicates with the interior of the first bottle neck 2. The annular protrusion 12 is spaced apart from the first inner wall 11, and at least a portion of the beer bottle neck is accommodated between the annular protrusion 12 and the first inner wall 11. By providing the annular protrusion 12, the sealing performance of the first cap 1 is increased, preventing beer leakage.

[0039] In the beer bottle cap assembly of this embodiment, see... Figure 3 A recessed groove 13 is formed on the side of the annular protrusion 12 near the first inner wall 11, and the groove 13 contains the mouth of a beer bottle. By setting the annular protrusion 12, the sealing performance of the first cap 1 is further increased. Specifically, the groove 13 includes a first sealing surface and a second sealing surface that are connected, and the angle between the two is ninety degrees.

[0040] In the beer bottle cap assembly of this embodiment, see... Figure 1The first cap 1 includes a mounting platform 14, which is located on the side of the first cap 1 away from the beer bottle body 10. A first bottle opening 2 is formed on the mounting platform 14, protruding from the mounting platform 14. By setting the mounting platform 14 and forming the first bottle opening 2, the mounting platform 14 makes it easier for the user to grip the first cap 1, thereby facilitating the screwing and installation of the first cap 1.

[0041] In some embodiments, the mounting platform 14 has a chamfered structure at its edge to avoid the second cover 3, so as to facilitate the screwing of the second cover 3.

[0042] In the beer bottle cap assembly of this embodiment, see... Figure 1 The second cover 3 includes anti-slip blocks 31, which protrude from the outer circumferential surface of the second cover 3. Multiple anti-slip blocks 31 are arranged in a circumferential array around the axis of the second cover 3. The design of the anti-slip blocks 31 increases the friction between the fingers and the second cover 3, making the cover more stable when twisting and reducing the possibility of hand slippage. This also makes the applied force more even and concentrated, facilitating easier rotation of the cover.

[0043] In some embodiments, a sealing structure is also provided inside the third cap 42, such as an annular protrusion structure provided in the third cap 42, to seal the liquid inside the beer bottle.

[0044] It is understood that the beer bottle cap combination in this application is not only applicable to beer bottles, but can also be widely used in other beverage containers containing gas, such as carbonated beverage bottles and soda bottles. Of course, it can also be used in beverage containers that do not contain gas.
