Description

Technical Field

[0001] This utility model specifically relates to a sealing structure for bubble bottles. Background Technology

[0002] With the rise of healthy eating trends, sparkling beverages and freshly squeezed juices have gained popularity among consumers due to their unique taste and rich nutritional content. Most existing equipment on the market separates sparkling water production from juicing, which not only increases the complexity of operation for users but also limits the integrated user experience. In view of this, the inventor previously applied for a patent with patent number CN202510150542.5, entitled "An Integrated Sparkling Juicer." This patent proposes an innovative sparkling beverage bottle design that can prepare sparkling drinks with unique flavors by injecting gases such as carbon dioxide while blending juice, greatly enriching the variety of beverages and enhancing the drinking experience.

[0003] However, in practical applications, it has been found that the aforementioned sparkling beverage bottles have certain limitations in terms of cleaning and maintenance. Since the interior requires regular cleaning to ensure hygiene and safety, the bottle body and base must be easily disassembled. However, considering that the interior of sparkling beverage bottles typically maintains a high pressure (e.g., after CO2 gas injection), improper design of the disassembly structure can easily lead to seal failure, resulting in gas leakage or liquid seepage. Poor sealing performance not only affects the normal use of the product but may also pose a potential threat to user safety. Furthermore, frequent disassembly and reassembly accelerates the aging of the seals, further reducing their effectiveness.

[0004] Therefore, how to achieve convenient disassembly and installation while ensuring good sealing has become an urgent problem to be solved. This utility model is an improvement solution proposed to address the shortcomings of existing technologies, aiming to provide a bubble bottle sealing structure that is both easy to disassemble and clean while maintaining excellent sealing performance. By optimizing the connection method between the bottle body and the base and the design of the sealing components, this utility model can achieve reliable sealing under high-pressure environments while simplifying the user's cleaning and maintenance process, extending the product's service life, and improving the overall safety and convenience of use.

[0005] This utility model was developed precisely because of the aforementioned shortcomings. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a bubble bottle sealing structure that is easy to disassemble and install while having good sealing performance.

[0007] This utility model is achieved through the following technical solution:

[0008] This utility model provides a sealing structure for a bubble bottle. The bubble bottle includes a bottle body, a base, and a cap. The bottle body and the base form a receiving cavity. The cap is connected to the top of the bottle body and closes the receiving cavity. The cap is provided with an injection structure for injecting gas. A sealing element is provided between the bottle body and the base. An upper threaded cylinder is provided at the bottom of the bottle body. A lower threaded cylinder is provided on the base and is threadedly connected to the upper threaded cylinder. The sealing element is annular and has a support ring portion for abutting against the base. After the upper threaded cylinder and the lower threaded cylinder are screwed together, the lower end of the upper threaded cylinder presses against the support ring portion. The support ring portion has an upwardly extending sealing ring portion.

[0009] In the bubble bottle sealing structure described above, the lower part of the sealing ring abuts against the inner wall of the upper threaded cylinder, and the side wall of the sealing ring near the upper threaded cylinder gradually slopes away from the upper threaded cylinder from bottom to top.

[0010] In the bubble bottle sealing structure described above, the included angle between the side wall of the sealing ring near the upper threaded cylinder and the inner wall of the upper threaded cylinder is α, and 0°<α≤15°.

[0011] As described above, in the bubble bottle sealing structure, the base is provided with a mounting ring groove for accommodating the support ring, so that the support ring can abut against the two side walls of the mounting ring groove.

[0012] As described above, in the bubble bottle sealing structure, the base has a snap-fit ​​ring groove at the bottom of the mounting ring groove, the support ring is connected to a snap-fit ​​ring that can be inserted into the snap-fit ​​ring groove, and the snap-fit ​​ring groove is correspondingly located below the upper threaded cylinder, so that the lower end of the upper threaded cylinder can press the snap-fit ​​ring into the snap-fit ​​ring groove.

[0013] The bubble bottle sealing structure described above features a seal made of food-grade silicone, which is a flexible, one-piece structure.

[0014] In the bubble bottle sealing structure described above, the sealing ring is vertically positioned and abuts against the inner wall of the upper threaded cylinder.

[0015] The bubble bottle sealing structure described above includes an injection structure comprising an injection channel on the bottle cap for external gas injection and a one-way valve disposed in the injection channel to prevent gas from escaping.

[0016] As described above, in the bubble bottle sealing structure, a stirring mechanism for stirring and juicing is connected to the base.

[0017] As described above, in the bubble bottle sealing structure, the base is provided with an upwardly protruding conical mounting platform, the stirring mechanism is connected to the mounting platform, and the sealing element is arranged around the mounting platform.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] 1. Achieving a balance between convenient disassembly and reliable sealing, the detachable connection structure of the upper and lower threaded cylinders, combined with the annular sealing design, ensures both the ease of disassembly and cleaning between the bottle body and the base, and the multi-stage sealing structure and self-reinforcing sealing mechanism of the sealing ring and support ring, which maintains good sealing performance even under high pressure, effectively solving the contradiction between the difficulty of cleaning and the insufficient sealing of existing bubble bottles.

[0020] 2. It has a self-reinforcing sealing function, which improves the safety of use. Under the high pressure inside the bottle, the sealing element can automatically deform and fit more tightly against the inner wall of the threaded cylinder, forming a self-sealing effect of "the greater the air pressure, the tighter the seal". Even in the case of slight leakage, the internal air pressure difference can achieve sealing compensation, which significantly improves the stability and long-term reliability of the sealing structure and ensures the safety of users.

[0021] 3. The structure is reasonably designed, the assembly stability is high, and it is easy to promote and apply. The sealing components are precisely positioned and firmly fixed through the installation ring groove and the snap ring groove, which prevents displacement or falling off during use. At the same time, it provides two sealing ring structures, namely inclined and vertical, which take into account both sealing performance and manufacturing and assembly convenience. It is suitable for a variety of carbonated beverage bottle products and has good prospects for industrial application. Attached Figure Description

[0028] The utility model will be further described below with reference to the accompanying drawings:

[0029] The orientations described in this utility model specification, such as "up," "down," "left," "right," "front," and "back," are based on the orientations in the accompanying drawings and are intended to facilitate the description of the relationships between the various components. They do not indicate the unique or absolute positional relationships between the various components, but are merely one embodiment of the utility model and are not a limitation on its implementation.

[0030] This embodiment describes a bubble bottle sealing structure, such as... Figures 1 to 4 As shown, the sparkling bottle includes a bottle body 1, a base 2, and a cap 3. The bottle body 1 and the base 2 form a receiving cavity 10. The bottle body 1 and the base 2 are detachably connected for easy cleaning and maintenance; the detachable structure is described below. The cap 3 is connected to the top of the bottle body 1 and can be threaded to tightly seal the bottle opening of the bottle body 1, thereby closing the receiving cavity 10. The cap 3 has a gas injection structure 30 for injecting gas. The gas injection structure 30 includes a gas injection channel 301 on the cap 3 for external gas injection and a one-way valve 302 in the gas injection channel 301 to prevent gas leakage. Structural principle explanation: The gas injection structure 30 injects external gas (such as CO2) through the gas injection channel 301, while the one-way valve 302 ensures that gas can only enter the bottle and cannot leak back, thus maintaining stable gas pressure inside the bottle. This structure is particularly suitable for sparkling water, sparkling juice, and other scenarios requiring carbonated storage or consumption. The threaded cap design not only provides excellent sealing but also makes it easy to open and close, simplifying user operation. The one-way valve design effectively prevents gas leakage and extends the shelf life of sparkling beverages.

[0031] A sealing element 4 is provided between the bottle body 1 and the base 2. Preferably, the sealing element 4 is a one-piece structure with elasticity made of food-grade silicone. However, it can also be a separate structure, or made of soft plastic or other rubber. Structural principle explanation: As a key sealing component between the bottle body 1 and the base 2, the sealing element 4, with its elastic material (such as food-grade silicone), can deform under the pressure of the threaded connection, filling the tiny gaps between the connecting surfaces, thereby forming a reliable sealing interface. The one-piece structure not only facilitates assembly but also reduces the fitting error between sealing elements; the food-grade silicone material is non-toxic and odorless, meets food safety standards, and is suitable for sealing food containers.

[0032] The bottle body 1 has an upper threaded cylinder 11 at its bottom, and the base 2 has a lower threaded cylinder 21 threadedly connected to the upper threaded cylinder 11. The sealing element 4 is annular and has a support ring portion 41 for abutting against the base 2. After the upper threaded cylinder 11 and the lower threaded cylinder 21 are screwed together, the lower end of the upper threaded cylinder 11 presses against the support ring portion 41. The support ring portion 41 has an upwardly extending, elastic sealing ring portion 42. At least the bottom of the support ring portion 41 abuts against the inner wall of the upper threaded cylinder 11, or the entire support ring portion 41 abuts against the inner wall of the upper threaded cylinder 11. Structural principle explanation: After the upper threaded cylinder 11 and the lower threaded cylinder 21 are screwed together, the lower end of the upper threaded cylinder 11 applies axial pressure to the support ring portion 41 of the sealing element 4, causing the sealing ring portion 42 to tightly adhere to the inner wall of the upper threaded cylinder 11, thereby forming a sealing interface. Figure 2 As shown, gas enters the bottle body from the top cap 3, causing the liquid inside to flow downwards in a liquid flow P. This downward flow P then disperses outwards, impacting the connection between the bottle body 1 and the base 2, increasing the risk of leakage. The upward-extending sealing ring 42 significantly reduces this risk. Furthermore, when high pressure is generated inside the bottle due to gas injection, if there is a minor leak at the sealing interface, the internal pressure will push the sealing ring 42 further against the inner wall of the threaded cylinder 11, creating a self-tightening sealing effect. This structure has excellent self-sealing performance; even in the event of a minor leak, the internal pressure enhances the sealing effect, improving overall sealing reliability.

[0033] With the above structure, the lower end of the upper threaded cylinder 11 presses the support ring 41 tightly against the base 2. The support ring 41, pressed against the inner wall of the upper threaded cylinder 11, forms a tight seal. If leakage occurs between the upper threaded cylinder 11 and the lower threaded cylinder 21, the high pressure inside the bottle creates a negative pressure between the support ring 41 and the inner wall of the upper threaded cylinder 11, causing the support ring 41 to press against the inner wall of the upper threaded cylinder 11, thus improving the sealing performance. Here, "negative pressure" refers to the initial stage of seal failure, where high-pressure gas inside the bottle attempts to escape through the leakage path, causing a localized pressure difference in the sealing element. This pressure difference pushes the sealing element to deform in the direction of leakage, thus automatically compensating for the seal failure. This design significantly improves the fault tolerance and long-term stability of the sealing structure.

[0034] In this embodiment, the seal 4 has two implementation methods:

[0035] One is that the sidewall of the sealing ring 42 is inclined, such as Figure 2 and Figure 6As shown, the lower part of the sealing ring 42 abuts against the inner wall of the upper threaded cylinder 11, and the side wall of the sealing ring 42 near the upper threaded cylinder 11 gradually slopes away from the upper threaded cylinder 11 from bottom to top. The side wall of the sealing ring 42 near the upper threaded cylinder 11, i.e., the outer ring wall 421, is inclined with the inner wall of the upper threaded cylinder 11 in its natural state to maintain a gap, which facilitates installation, makes the structure more stable, and facilitates disassembly and cleaning maintenance. When the gas pressure inside the bottle is high, the sealing ring 42 can deform and abut against the outer ring wall 421. Therefore, the included angle between the outer ring wall 421 and the inner wall of the upper threaded cylinder 11 is α, and 1°≤α≤10°. Of course, in practical applications, 0°<α≤15° can also be selected. Structural principle explanation: as Figure 2 As shown, gas enters the bottle body from the top cap 3, causing the liquid inside to flow downwards in a liquid flow P. This downward flow P then disperses outwards, impacting the connection between the bottle body 1 and the base 2, increasing the risk of leakage. The upward-extending sealing ring 42 significantly reduces this risk. Furthermore, the inclined sealing ring 42 maintains a small gap with the inner wall of the upper threaded cylinder 11 in its natural state, facilitating assembly and disassembly. When the internal gas pressure increases, the sealing ring 42 undergoes elastic deformation under pressure, and the outer ring wall 421 tightly adheres to the inner wall of the upper threaded cylinder 11, forming a seal. The inclined angle α balances assembly convenience and sealing performance, ensuring automatic sealing under high pressure while avoiding deformation damage caused by overly tight assembly.

[0036] Secondly, the sealing ring 42 is vertically arranged, such as... Figure 5 As shown, the sealing ring 42 is vertically positioned and abuts against the inner wall of the upper threaded cylinder 11. Alternatively, a gap of 0.05mm to 0.1mm can be maintained between the sealing ring 42 and the inner wall of the upper threaded cylinder 11. The vertical sealing ring 42 directly abuts against the inner wall of the upper threaded cylinder 11, resulting in a simple structure and good manufacturing and assembly processability. The 0.05-0.1mm gap prevents sealing failure due to assembly errors, while still ensuring a good seal under air pressure. This structure is suitable for products with moderate sealing requirements and strict manufacturing cost control, offering good versatility and replaceability.

[0037] As a preferred option, such as Figure 2 As shown, to facilitate the installation and fixing of the sealing element 4, the base 2 is provided with a mounting ring groove 22 for accommodating the support ring 41, allowing the support ring 41 to rest against the two side walls of the mounting ring groove 22. The mounting ring groove 22 provides positioning space for the support ring 41, preventing it from shifting during assembly and ensuring the fitting accuracy between the sealing element and the bottle body. This improves assembly consistency and stability, and reduces the risk of seal failure due to assembly errors.

[0038] As a further optimization plan, such as Figure 2As shown, the base 2 has a snap-fit ​​ring groove 23 at the bottom of the mounting ring groove 22. The support ring 41 is connected to a snap-fit ​​ring part 43 that can be inserted into the snap-fit ​​ring groove 23. The snap-fit ​​ring groove 23 is correspondingly located below the upper threaded cylinder 11, so that the lower end of the upper threaded cylinder 11 can press the snap-fit ​​ring part 43 into the snap-fit ​​ring groove 23, which not only improves the stability and firmness of the installation, but also enhances the sealing performance.

[0039] The snap-fit ​​ring 43 and the snap-fit ​​ring groove 23 form a mechanical locking structure. During the tightening of the upper threaded cylinder 11, its lower end presses the snap-fit ​​ring 43 into the snap-fit ​​ring groove 23, preventing the seal from shifting or falling off during use. The snap-fit ​​structure enhances the fixing reliability of the seal, avoids seal failure due to vibration or pressure changes, and improves the overall durability of the structure.

[0040] In detail, such as Figures 2 to 4 As shown, a stirring mechanism 5 for stirring and juicing is connected to the base 2. The stirring mechanism 5 includes a stirring blade located inside the bottle for stirring and juicing, and a transmission component for connecting to a transmission structure to achieve rotation. The stirring mechanism 5 is connected to an external drive device (such as a motor) through the base 2. The stirring blade rotates under the drive of the transmission component, realizing the functions of liquid stirring or fruit juicing. The bubble bottle with integrated stirring function can realize the integrated operation of "stirring + aeration", meet the diverse needs of users, and enhance the added value of the product.

[0041] The base 2 has an upwardly protruding, cone-shaped mounting platform 24. The stirring mechanism 5 is connected to the mounting platform 24, and the sealing element 4 is arranged around the mounting platform 24. Structural principle explanation: The cone-shaped mounting platform 24 provides mounting support for the stirring mechanism 5, while the sealing element 4 surrounding it ensures a tight seal between the stirring mechanism and the base. The cone-shaped structure helps the sealing element to automatically align during assembly, improving sealing reliability; it also helps to form a stable pressure inside the sealing element 4.

[0042] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model. These modifications will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application shall be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
