Abstract
Description
Technical Field
[0001] This utility model relates to the cap of a liquid container, and in particular to a rotating, retractable spout and bottle cap. Background Technology
[0002] Bottle caps have a wide range of applications in the field of liquid containers. In daily life, there are many types of liquid containers with caps, such as oil bottles, soy sauce bottles, and vinegar bottles. These containers are equipped with caps with spouts for pouring liquids. To prevent dust from settling on the spout, existing technologies often include a flip-up top cover to shield the top of the spout, effectively preventing dust accumulation. Some existing designs also feature rotating, retractable spouts, such as Chinese patent CN 219215808 U, which uses a rotating spout for opening or closing. However, in existing technologies, rotating the spout requires direct contact, which can soil hands and compromise liquid cleanliness. Therefore, designing a simpler structure that avoids direct contact with the spout is essential. Utility Model Content
[0003] This application proposes a rotating, retractable spout and bottle cap, which aims to solve many technical problems such as hygiene and cleaning caused by the need for direct contact between the spout and the bottle cap during rotation in the prior art.
[0004] The technical solution adopted by the utility model is: a rotating and retractable flow guide nozzle, the flow guide nozzle including a cover body, the cover body having a storage groove, a clearance opening on one side of the storage groove for the flow guide nozzle to rotate through, a mounting groove at the bottom of the storage groove, a rotating support seat located in the mounting groove at one end of the flow guide nozzle, a pressing cover at the top opening of the storage groove, the pressing cover being rotatably connected to the storage groove, and a rib plate at the lower end of the pressing cover, the rib plate having a guide groove, the flow guide nozzle having a sliding rod, the sliding rod being movably disposed in the guide groove.
[0005] Furthermore, the bottom surface of the mounting groove is arc-shaped, and the bottom surface of the rotating support is arc-shaped and fits against the bottom surface of the mounting groove; the mounting groove is provided with first shaft holes on both sides, and the rotating support is provided with a first rotating shaft, the first shaft holes being adapted to the first rotating shaft.
[0006] Furthermore, the storage slot is provided with second shaft holes on both sides of the relief opening, and the pressing cover is provided with a matching second rotating shaft, which is located on the side of the pressing cover biased towards the relief opening.
[0007] Furthermore, a liquid outlet is provided in the mounting groove. When the rotating support base rotates to the second position where the guide nozzle is open, the inlet of the guide nozzle is connected to the liquid outlet. When the rotating support base rotates to the first position where the guide nozzle is retracted, the inlet of the guide nozzle is offset from and connected to the liquid outlet.
[0008] Furthermore, the cross-section of the flow guide nozzle is circular.
[0009] Furthermore, the inner surface of the mounting groove is provided with a leak-proof membrane.
[0010] This utility model further proposes a bottle cap using the aforementioned guide nozzle structure.
[0011] This invention utilizes a press-fit cap to allow the nozzle to rotate, open, and retract without requiring contact with the nozzle, thus ensuring cleanliness and hygiene during rotation. Furthermore, the press-fit cap provides excellent coverage. This design eliminates the need for additional redundant structures, minimizing the complexity of the nozzle's design.

[0020] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0021] This utility model innovatively discloses a flow guide nozzle structure with a reflux function. Thanks to its superior design concept and high versatility, this structure can be seamlessly adapted to various liquid containers. It demonstrates strong practical value in both everyday beverage packaging and chemical raw material storage containers in industrial production. From a structural application perspective, the flow guide nozzle 1 can cleverly serve as an indispensable component of the container cap, working in conjunction with the cap to achieve convenient integrated operation; alternatively, it can be directly integrated into the container using advanced manufacturing processes, providing an efficient solution for precise liquid pouring. To facilitate understanding of the technical content of this utility model, this paper will use the application of the flow guide nozzle 1 structure on bottle caps as a typical example for detailed explanation. However, it should be emphasized that in practical applications, the applicability of this structure is extremely broad, not limited to bottle caps as a specific carrier. It can be easily adapted to various shapes of plastic bottles, glass bottles, and large industrial liquid storage tanks.
[0022] According to the appendix Figure 1 , 2As clearly illustrated in Figure 3, the structure of the guide nozzle 1 of this utility model mainly consists of two core parts: the guide nozzle 1 and the mounting base. The guide nozzle 1, as a key component for liquid flow guidance, is mounted on the mounting base in a flexible, rotatable manner thanks to a cleverly designed rotating support base 3. The mounting base plays a crucial role in the entire structural system. Through precise manufacturing processes, it can become an integral part of the container body structure; it can also serve as a core component of the container cover 18, working in conjunction with the cover 18. The core function of the mounting base is to provide a stable and reliable mounting foundation for the guide nozzle 1, ensuring that the guide nozzle 1 will not experience shaking, displacement, or other instability during use. Simultaneously, the structural design of the mounting base fully considers the rotation requirements of the guide nozzle 1. Through reasonable mechanical design and structural layout, it ensures that the guide nozzle 1 can rotate flexibly within a certain angle range, meeting the diverse needs for liquid pouring angles in different usage scenarios.
[0023] Specifically, the guide nozzle 1 has two key openings. The opening at the top of the guide nozzle 1 is defined as the outlet 5, which plays a crucial role in accurately guiding the liquid inside the container to the outside. The other opening, seamlessly connected to the inside of the container, is called the inlet 6, which provides a smooth channel for the liquid inside the container to flow into the guide nozzle 1. It is worth mentioning that the structural design of the guide nozzle 1 exhibits extremely high flexibility and versatility. Under conventional design principles, a simple and practical straight tube structure can be adopted, and the cross-sectional shape of the tube can be flexibly selected as circular, rectangular, or other irregular shapes according to actual usage requirements. At the same time, the size of the tube cross-section can also be optimized from bottom to top based on parameters such as the liquid's flow rate and volume. Furthermore, this invention fully accommodates various special forms in existing designs. For example, a specific curvature can be set on the inner wall of the guide nozzle 1 to optimize the liquid flow path using fluid dynamics principles and improve guiding efficiency; or the outlet 5 can be designed as a beak shape, a beveled cut, or other special shapes to meet the pouring requirements of different liquid characteristics (such as high-viscosity liquids, volatile liquids, etc.). It can be said that this utility model adopts an open and inclusive attitude towards the specific structural form of the guide nozzle 1, covering all known existing design forms, and fully reflects its technological foresight and versatility.
[0024] The inlet 6 is located at the bottom of the rotating support 3, and is further integrated with the attached... Figures 3 to 6The mounting base is specially equipped with a mounting groove 2 for mounting the rotating support base 3, and the mounting groove 2 also has a carefully designed overflow port 7. This seemingly simple design detail contains ingenious technical conception. When the rotating support base 3 and the mounting groove 2 are rotated to the first position where the guide nozzle 1 is retracted under the operation of the user, the guide nozzle 1 is in the retracted state, and the entire structure enters the liquid recovery mode. In this mode, the inlet 6 and the overflow port 7 are partially connected, allowing the liquid remaining inside and outside the guide nozzle 1 to flow smoothly back into the container under the action of gravity through the overflow port 7, completing the liquid recovery process. When the rotating support base 3 and the mounting groove 2 are rotated to the second position where the guide nozzle 1 is open, the structure switches to the liquid pouring function mode. In this mode, the inlet 6 and the overflow port 7 are quickly connected, so that during the liquid pouring process, the liquid can flow smoothly from the inlet 6 through the outlet 5 of the guide nozzle 1 along the preset flow channel, effectively avoiding the liquid entering the return flow channel and causing backflow, ensuring the smoothness and stability of the liquid pouring process.
[0025] The specific implementation is as follows: In the first position, the inlet 6 and the outlet 7 are partially connected to form a small hole. This small hole design is ingenious, as it provides a slow backflow channel for the liquid remaining inside the guide nozzle 1, avoiding problems such as liquid splashing due to excessive backflow speed. In the second position, the inlet 6 and the outlet 7 are completely overlapped and connected, opening up a wide and smooth main channel for liquid pouring.
[0026] Specifically, when the cross-section of the guide nozzle 1 is set to circular, the liquid guidance effect during the guiding process reaches its optimal state, the liquid flow is smoother, and the resistance and turbulence of the liquid in the flow channel can be effectively reduced, improving the efficiency and accuracy of liquid pouring. When the length of the guide nozzle 1 is repeatedly optimized and set to 3cm, and the total height of the guide nozzle 1 and the rotating support 3 is precisely controlled at 4.5cm, both the liquid pouring and return effects reach their optimal levels. Under this parameter combination, an ideal balance can be achieved in terms of liquid pouring speed, flow control, and residual liquid recovery efficiency, bringing users an ultimate user experience.
[0027] In a typical embodiment of practical application, the nozzle 1 is precisely installed on the cap 18, which is the bottle cap body commonly seen in our daily lives. A protruding storage groove 8 is specially designed on the top of the cap 18. The existence of this storage groove 8 is of great significance; its main function is to store the nozzle 1, preventing it from accumulating dust when exposed during idle periods, thus affecting the product's hygiene and performance. A through-hole 9 is provided on one side of the storage groove 8, providing ample space and a convenient channel for the rotation of the nozzle 1. When the nozzle 1 rotates out of the through-hole 9, it naturally tilts, with the outlet 5 located outside the storage groove 8, creating excellent conditions for liquid outflow and facilitating smooth liquid flow. The mounting groove 2 is located at the bottom of the storage groove 8 and is used to install the rotating support 3. The bottom surface of the mounting groove 2 is carefully designed and curved, and the bottom surface of the rotating support 3 fits closely to it, also being curved. The mounting groove 2 has first shaft holes 11 on both sides, and the rotating support 3 has a matching first rotating shaft 12. The rotating support 3 is installed in the mounting groove 2 through the first rotating shaft 12. During the rotation of the rotating support 3, its arc-shaped bottom surface always keeps in close contact with the arc-shaped surface of the mounting groove 2. This design can not only effectively reduce the frictional resistance during the rotation process, but also greatly ensure the stability of the rotation, ensuring that the guide nozzle 1 will not shake or jam during the rotation process, providing a solid guarantee for the stable realization of the liquid pouring and backflow function.
[0028] In addition, a pressing cover 10 is provided at the top opening of the storage slot 8, and the pressing cover 10 is rotatably connected to the storage slot 8. Second shaft holes 13 are provided on both sides of the clearance opening 9 in the storage slot 8. A matching second rotating shaft 14 is provided on the pressing cover 10, located on the side of the pressing cover 10 biased towards the clearance opening 9. A pair of ribs 15 are provided at the lower end of the pressing cover 10. The ribs 15 have vertically extending guide grooves 16, and the flow nozzle 1 has a sliding rod 17 that can move within the guide grooves 16. The first rotating shaft supports the flexible rotation of the flow nozzle 1; the second rotating shaft provides stable power for the rotation of the pressing cover 10. The guide groove 16 and the sliding rod 17 cooperate to limit the rotation trajectory of the flow nozzle 1, ensuring that it rotates along a preset path and avoiding rotational deviation. When the right side of the press cover 10 is pulled upwards, the press cover 10 acts like an activated "mechanical arm," quickly rotating and driving the guide nozzle 1 to turn right out of the clearance port 9, smoothly realizing the liquid pouring function; when the right side of the press cover 10 is pressed downwards, the press cover 10 drives the guide nozzle 1 to turn left and retract into the storage groove 8. At this time, the press cover 10 tightly covers the guide nozzle 1, playing a good protective role and effectively protecting the structure of the guide nozzle 1 from external pollution and damage. This utility model uses the press cover to realize the rotation, opening and storage of the guide nozzle without contacting the guide nozzle throughout the process, thus ensuring the cleanliness and hygiene of the guide nozzle during rotation. Moreover, the press cover can provide a good covering effect. Under this structure, there is no need to add new redundant structures, ensuring the simplicity of the guide nozzle structure as much as possible.
[0029] To prevent leakage during the opening and closing of the nozzle 1, liquid pouring, and backflow, a flexible leak-proof membrane is installed on the inner surface of the mounting groove 2. This leak-proof membrane is made of a special polymer material, possessing excellent flexibility and sealing properties. During installation, the leak-proof membrane adheres tightly to the surface of the mounting groove 2, forming a good seal and effectively eliminating the risk of liquid leakage, ensuring the safety and hygiene of the product.
[0030] Based on the meticulously designed nozzle 1 structure described above, this utility model further proposes a bottle cap incorporating this structure. This integrated design concept perfectly combines the nozzle 1 structure with the bottle cap, providing users with a more convenient, efficient, and practical liquid container solution.
[0031] Working principle
[0032] When liquid needs to be poured, the user simply needs to gently pry up the right side of the press cap 10. The press cap 10 will then rotate rapidly at the top opening of the receiving slot 8, using the second rotating shaft 14 as a fulcrum. The guide groove 16 of the lower rib plate 15 of the press cap 10 cooperates with the slide rod 17 on the guide nozzle 1, driving the guide nozzle 1 to rotate smoothly around the first rotating shaft 12 within the mounting slot 2, rotating out of the relief opening 9 of the receiving slot 8 to an inclined state, so that the outlet 5 is located outside the receiving slot 8. At this time, driven by this series of mechanical movements, the rotating support 3 precisely rotates to the second position where the guide nozzle 1 is open. The inlet 6 of the guide nozzle 1 is completely aligned and connected with the liquid outlet 7 in the mounting slot 2 of the mounting base. Under the action of gravity, the liquid in the container is smoothly poured out of the container from the inlet 6 through the outlet 5 of the guide nozzle 1, achieving an efficient and precise liquid pouring process.
[0033] After the liquid has been poured out, the user presses down on the right side of the press cap 10. The press cap 10 quickly drives the guide nozzle 1 to rotate in the opposite direction, causing it to retract into the collection tank 8. When the rotating support 3 rotates to the first position where the guide nozzle 1 is retracted, the inlet 6 and the liquid outlet 7 partially connect to form a small hole. The liquid remaining inside the guide nozzle 1 also slowly flows back into the container through this small hole and the liquid outlet 7, achieving efficient recovery of the residual liquid. This fully demonstrates the positive significance of this utility model in terms of resource conservation and environmental protection.
[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
