Description

Technical Field

[0001] This utility model relates to the technical field of oil bottle caps, and specifically discloses a telescopic oil bottle cap with a sealing pull ring. Background Technology

[0002] Oil bottle caps are components used to seal the opening of oil bottles or containers. They are very common in daily life and are mainly used for holding and storing edible oils such as olive oil, soy sauce, and sesame oil. However, people often encounter many inconveniences when pouring oil from oil bottles. Traditional oil bottle caps have short spouts, making it difficult to accurately reach the filling opening when pouring oil into containers with small openings or deep locations, making the pouring process extremely difficult. Moreover, oil is prone to spillage during pouring, which not only wastes resources but also makes a mess of the surrounding environment, causing significant cleanup problems. More seriously, spilled oil can pose a serious safety hazard if it comes into contact with an open flame. To solve these problems, retractable oil bottle caps have gradually appeared on the market.

[0003] Existing telescopic oil bottle caps typically consist of an outer sleeve, an nozzle, a spring, and a top cap. The spring allows the nozzle to extend from the inner cavity of the outer sleeve for easy pouring; when not in use, the top cap retracts the nozzle back into the outer sleeve. However, these telescopic oil bottle caps are mostly sold as additional accessories for soy sauce bottles, rarely used as the original caps at the factory. This is because the top cap and outer sleeve use an easy-open connection, resulting in poor sealing. Furthermore, during product transportation, vibrations can easily cause the spring to push the top cap out, leading to leakage. Therefore, there is an urgent need for a telescopic oil bottle cap with better sealing, capable of meeting the usage requirements of soy sauce bottles and other oil bottles at the factory, ensuring no leakage during transportation and storage, while also providing convenience for consumers.

[0032] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Example 1

[0034] This embodiment discloses a telescopic oil bottle cap with a sealing pull ring, referring to... Figure 1 , Figure 2a , Figure 2b , Figure 3 , Figures 4a-4c It includes a bottle stopper outer sleeve 1, a bottle stopper inner liner 2, a telescopic nozzle 3, and a top cap 4. The bottle stopper outer sleeve 1 is a component that matches and is installed with the mouth of the oil bottle. The bottle stopper outer sleeve 1 has an oil pouring port 11 inside, and the oil pouring port 11 has a removable sealing ring 12 for sealing. The bottle stopper inner liner 2 is disposed inside the bottle stopper outer sleeve 1, and a snap-fit ​​structure is provided between the bottle stopper inner liner 2 and the bottle stopper outer sleeve 1 for detachable connection. The bottle stopper inner liner 2 has an oil pouring chamber 21, and the top of the oil pouring chamber 21 has an installation port 211 corresponding to and communicating with the oil pouring port. The bottom of the bottle stopper inner liner 2 has an oil inlet hole 212. The telescopic nozzle 3 is movably sleeved inside the bottle stopper inner liner 2, and the telescopic nozzle 3 includes an nozzle part and an elastic part 3. 3. A travel limiting structure is provided between the nozzle and the bottle stopper liner 2. The elastic part 33 can be a spring. One end of the elastic part 33 acts on the bottle stopper liner 2, and the other end acts on the nozzle. The sealing pull ring 21 abuts against the nozzle to overcome the elastic force of the elastic part 33 and compresses the telescopic nozzle 3 into the pouring chamber 21. The top cover 4 is installed on the top of the bottle stopper outer sleeve 1. It is used to replace the sealing pull ring 21 after compression of the telescopic nozzle 3. In this embodiment, the top cover 4 is snap-on installed on the top of the bottle stopper outer sleeve 1. In other embodiments, it can also be installed on the top of the bottle stopper outer sleeve 1 by a threaded cap. This structural design of the solution can ensure that the oil bottle cap has good sealing performance when it leaves the factory, facilitates pouring oil during use, and effectively prevents leakage. During assembly, the telescopic nozzle 3 can be pressed into the pouring chamber 21 from the installation port on the top of the bottle stopper liner 2, and then the bottle stopper liner 2 and the bottle stopper outer sleeve 1 can be connected by a snap-on structure to complete the assembly.

[0035] As a preferred option, refer to Figure 4a , Figure 4b , Figure 4b for Figure 4a The enlarged view at point B shows the snap-fit ​​structure, which includes a snap-fit ​​protrusion 13 on the inner wall of the bottle stopper outer sleeve 1 and a snap-fit ​​groove 22 on the outer side of the bottle stopper liner 2 that matches and snaps into the protrusion 13. This snap-fit ​​structure ensures a tight connection between the bottle stopper liner 2 and the bottle stopper outer sleeve 1, and facilitates disassembly, which is beneficial for production and subsequent maintenance and replacement. In other embodiments, the snap-fit ​​groove 22 and the snap-fit ​​protrusion 13 can be interchanged.

[0036] As a preferred option, refer to Figure 4a , Figure 4b A limiting groove 15 is provided below the oil pouring port 11 of the bottle stopper outer sleeve 1, and the top of the bottle stopper inner liner 2 abuts against the bottom surface of the limiting groove 15. The design of the limiting groove 15 can restrict the installation position of the bottle stopper inner liner 2, prevent it from moving excessively upward, ensure accurate communication between the oil pouring port 11 and the installation port 211, and also help improve the stability of the structure.

[0037] As a preferred option, refer to Figure 3 The inner wall of the bottle stopper outer sleeve 1 is provided with an axially extending positioning block 14, and the outer side of the bottle stopper inner liner 2 is provided with an axially penetrating positioning groove 23, which is inserted into the positioning block 14. The cooperation between the positioning block 14 and the positioning groove 23 can ensure the accuracy of the position of the bottle stopper inner liner 2 during installation, avoid displacement, and thus ensure the structural stability of the entire oil bottle cap.

[0038] As a preferred option, refer to Figure 2a , Figure 2b , Figure 2b for Figure 2a The enlarged view at point A shows that the nozzle assembly includes a slidingly fitted outer nozzle 31 and an inner nozzle 32. The lower end of the inner nozzle 32 has a limiting protrusion 321. The inner wall of the outer nozzle 31 is limited by a limiting step 311 that abuts against the limiting protrusion 321. One end of the elastic part 33 acts on the nozzle assembly by abutting against the limiting protrusion 321 of the inner nozzle 32. This structure of the inner and outer nozzles, combined with the elastic part 33, allows the nozzle assembly to extend and retract flexibly, facilitating its extension during oil pouring and retraction when not in use. Simultaneously, the cooperation of the limiting protrusion 321 and the limiting step 311 prevents the inner nozzle 32 from detaching, ensuring safety during use. Of course, in other embodiments, the nozzle assembly can be a single section, or three or more sections, achieving the same telescopic nozzle function through the design of corresponding limiting steps and protrusions.

[0039] As a preferred embodiment, the limiting protrusion 321 of the inner nozzle 32 is provided with a stop groove 322. One end of the elastic part 33 acts on the nozzle by abutting against the stop groove 322 of the limiting protrusion 321. The stop groove 322 provides a stable abutment point for the elastic part 33, allowing the elastic part 33 to function better and ensuring the stability and reliability of the nozzle during the extension and retraction process. Furthermore, a stop rod 323 is provided in the stop groove 322, located at the top of the elastic part 33. The stop rod 323 can further restrict the position of the elastic part 33, preventing excessive deformation or detachment of the elastic part 33 during the extension and retraction process, enhancing the stability and safety of the entire oil bottle cap structure, ensuring that the oil bottle cap maintains good performance during long-term use, and reducing the risk of malfunction.

[0040] As a preferred option, refer to Figure 4a , Figure 4c , Figure 4c for Figure 4a The enlarged view at point C shows the stroke limiting structure, which includes: a snap-fit ​​flange 312 at the lower end of the outer nozzle 31; and a stop step 24 on the inner wall of the pouring chamber 21 of the bottle stopper liner 2 engaging with the snap-fit ​​flange 312 for limiting the stroke. The elastic modulus of the snap-fit ​​flange 312 is configured to allow elastic contraction into the mounting opening 211, and to elastically return to engaging with the stop step 24. The stop step 24 engages with the snap-fit ​​flange 312 to prevent the outer nozzle 31 from disengaging from the bottle stopper liner 2. The stroke limiting structure restricts the extension length of the telescopic nozzle, preventing excessive extension that could cause damage or difficulty in retraction. In other embodiments, a matching connection between a plug and a long slot can also achieve the stroke limiting function.

[0041] As a preferred embodiment, a traction member 41 connects the top cap 4 and the bottle stopper outer sleeve 1. The traction member 41 prevents the top cap 4 from being lost during use, allowing the user to easily open the top cap 4 when needing to pour oil, and to close it promptly afterward to maintain a good seal. In this embodiment, the top cap 4, traction member 41, and bottle stopper outer sleeve 1 are integrally injection molded. This integral injection molding design increases the structural integrity and robustness, improves the product's lifespan, reduces production costs, and facilitates large-scale manufacturing.

[0042] Example 2

[0043] This embodiment discloses a telescopic oil bottle cap with a sealing pull ring, which differs from Embodiment 1 in that, referring to... Figure 5 In this embodiment, the inner nozzle 32 and the elastic part 33 are integrally injection molded and connected. Compared with the elastic part 33 and the nozzle part of Embodiment 1, which are separate structures, the integral structure of the inner nozzle 32 and the elastic part 33 does not require the installation of an additional independent spring, which reduces the number of parts, simplifies the installation steps and difficulty, improves production efficiency, and reduces production costs.

[0044] The technical solution provided by this utility model has been described in detail above. Specific examples have been used to illustrate the principle and implementation of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
