Technical Field
[0001] This utility model relates to the cap of a liquid container, and in particular to a recyclable bottle cap and bottle. 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 bottles, sauce bottles, and vinegar bottles, all of which are equipped with caps with spouts to allow liquids to be poured out. However, with prolonged use, leaking liquid can easily flow along the outside of the spout to the top of the cap, forming residue. Over time, this residue can easily mix with dust and become difficult to clean. For example, the bottle spout proposed in the prior art CN86205143U involves air passing through the upper end of a bottle stopper with two holes drilled axially. One hole connects to an oil guide tube for oil flow in and out; the other connects to an oil collection groove surrounding the guide tube. The bottom of the groove communicates with the small hole in the bottle stopper. The lower end of the bottle stopper connects to a return pipe through the small hole. The inner diameter of the lower end of the return pipe is very small, providing a sealing effect during pouring. This allows the oil on the bottle spout to seep along the outside to the oil collection groove, and then flow back into the bottle through the small hole and the return pipe. However, in the existing technologies represented by the aforementioned patents, both the oil collection tank and the oil guide pipe are exposed to the environment, making it impossible to effectively shield the oil guide pipe and the oil collection tank. They are prone to dust accumulation and difficult to clean. Utility Model Content
[0003] This application proposes a recyclable bottle cap and bottle, which aims to solve the problems existing in the prior art where, when liquid is poured out of the cap of a liquid container for a long time, liquid tends to remain outside the cap, and the oil outlet and other oil ports of the cap are exposed for a long time, and the residual liquid tends to accumulate dust and form stubborn stains, making it difficult to clean.
[0004] The technical solution adopted by the utility model is: a recyclable bottle cap, which includes a cap body, a storage groove and a liquid outlet tube on the top of the cap body, a rotating support block at one end of the liquid outlet tube, the liquid outlet tube being rotatably connected to the cap body through the rotating support block, the liquid outlet tube being rotatably stored in the storage groove, and a return pipe for guiding the liquid at the outlet end of the liquid outlet tube into the cap body on one side.
[0005] Furthermore, the top of the storage tank is provided with an upper cover, and one side of the storage tank is provided with a slot for the liquid outlet pipe to pass through. A slot is provided on the cover body, and the slot is located at the connection between the storage tank and the cover body. The rotating support block is rotatably engaged in the slot.
[0006] Furthermore, the cover is also provided with a spring-loaded snap-fit component, which is elastically connected to the cover. The spring-loaded snap-fit component is provided with a first snap-fit element, and the liquid outlet tube is provided with a second snap-fit element. When the liquid outlet tube is stored in the storage groove, the first snap-fit element and the second snap-fit element are snapped together. After pressing the spring-loaded snap-fit component, the first snap-fit element and the second snap-fit element are disengaged.
[0007] Furthermore, the second snap-fit element is a snap-fit connector, and the first snap-fit element is a snap-fit groove, the opening shape of which is adapted to the elastic movement trajectory of the spring-loaded snap-fit element.
[0008] Furthermore, the card connector is provided with a slot, and the card slot is provided with a card body that is adapted to the slot.
[0009] Furthermore, the cover is provided with a sliding groove, the spring-loaded snap fastener is slidably disposed in the sliding groove, and a first elastic element is provided between the spring-loaded snap fastener and the sliding groove. The storage groove is provided with an opening for the second snap fastener to pass through, and the spring-loaded snap fastener is disposed outside the opening of the storage groove.
[0010] Furthermore, the inner wall of the slide groove is provided with at least one slide channel, and the spring-loaded snap-fit component is provided with a slider that is adapted to the slide channel.
[0011] Furthermore, the cover is provided with a slot, and the rotating support block is rotatably engaged in the slot. A second elastic element is also provided between the rotating support block and the slot to elastically rotate the liquid outlet pipe outwards into the receiving groove.
[0012] Furthermore, the rotating support block is provided with a central shaft, the slot is provided with a shaft hole, the central shaft is disposed in the shaft hole, and the second elastic element is a torsion spring, which is sleeved on the central shaft.
[0013] This invention further proposes a bottle that includes the aforementioned recyclable bottle cap.
[0014] This invention features a rotating support block at one end of the outlet pipe, allowing it to rotate on the cap. When not in use, the outlet pipe can be rotated into the storage slot, effectively saving space and protecting the pipe. A return pipe is also fixedly installed on one side of the outlet pipe, guiding any leaked liquid back into the cap, preventing spillage and waste. This perfectly solves the problems of existing liquid containers where liquid residue easily remains outside the cap after prolonged pouring, and where oil outlets such as the grease fitting are exposed for extended periods, leading to dust accumulation and stubborn stains that are difficult to clean.

[0023] To make the technical problem to be solved, the technical solution, and the 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.
[0024] This utility model provides a recyclable bottle cap, combined with an attached... Figures 1 to 6 As shown, the retractable bottle cap includes a cap body 1, a liquid outlet pipe 3, a liquid return pipe 5, a spring-loaded snap fastener 9, a first elastic element 15, a storage groove 2, an upper cover 6, a rotating support block 4, and a second elastic element 20.
[0025] The cap 1 has an internal thread that is specifically designed to match the bottle opening. The pitch, thread profile, and other parameters of this thread are precisely designed to ensure a tight fit with the bottle opening, thus securing it firmly to the bottle and forming a good seal to prevent oil leakage. Figure 1 As shown, a storage groove 2 is provided on the top of the cover 1. A slot 8 is opened at the connection between the storage groove 2 and the cover 1. The dimensional accuracy of the slot 8 is extremely high, and the fit tolerance with the rotating support block 4 is controlled within a very small range, providing stable support for the rotation of the liquid outlet pipe 3.
[0026] Furthermore, in conjunction with the appendix Figure 2 , 3 As shown in Figure 4, a rotating support block 4 is located at one end of the outlet pipe 3. The central shaft 19 on the support block and the shaft hole in the slot 8 of the cover 1 fit together perfectly. This fit is not a simple connection, but a carefully designed one. The difference between the inner diameter of the shaft hole and the diameter of the central shaft 19 is accurate to the micrometer level, ensuring that the outlet pipe 3 can rotate flexibly without shaking or shifting. When not in use, the outlet pipe 3 can be rotated into the storage slot 2, effectively saving space and protecting the outlet pipe 3. A return pipe 5 is also fixedly installed on one side of the outlet pipe 3. The return pipe 5 can be firmly connected to the outlet pipe 3 and the cover 1 through a hot-melt welding process that involves heating and melting materials. This hot-melt welding process is precisely controlled at high temperatures, allowing the connection between the return pipe 5 and the outlet pipe 3 and the cover 1 to achieve a molecular-level bond, ensuring a strong connection. Alternatively, the return pipe 5 can be integrally formed with the outlet pipe 3. The return pipe 5 guides any liquid that may drip after the liquid is poured out of the outlet pipe 3 back into the cover 1, preventing liquid from dripping onto the outside and causing pollution and waste.
[0027] Furthermore, such as Figure 4 , 5 As shown, there is also a groove 14 on the cover 1, which is used to install the spring-loaded snap-fit connector 9. The inner wall of the groove 14 is finely polished to ensure smooth cooperation with the slider 18 on the spring-loaded snap-fit connector 9, ensuring the stability and reliability of the spring-loaded snap-fit connector 9 when sliding. The spring-loaded snap-fit connector 9 is installed in the groove 14 of the cover 1 and can slide smoothly in the groove 14. The inner wall of the groove 14 is provided with a slide rail 17. The slider 18 on the spring-loaded snap-fit connector 9 and the slide rail 17 on the inner wall of the groove 14 fit together perfectly, ensuring that its sliding trajectory is stable and accurate. The design of the slide rail 17 not only increases the friction between the slider 18 and the groove 14 to prevent the spring-loaded snap-fit connector 9 from sliding accidentally, but also guides the spring-loaded snap-fit connector 9 to slide down along a predetermined trajectory when it is pressed. Between the spring-loaded snap-fit connector 9 and the bottom of the slide 14, a first elastic element 15 is installed. Under normal conditions, it keeps the spring-loaded snap-fit connector 9 in a stable position. The elastic coefficient of the first elastic element 15 has been repeatedly tested and optimized to ensure that while providing sufficient elastic force, the spring-loaded snap-fit connector 9 will not be difficult to operate due to excessive elastic force.
[0028] Furthermore, in conjunction with the appendix Figure 3 , 4 As shown in Figures 5 and 6, the spring-loaded snap-fit component 9 is provided with a first snap-fit element 10, and the liquid outlet tube 3 is provided with a second snap-fit element 11. When the liquid outlet tube 3 is stored in the storage groove 2, the first snap-fit element 10 and the second snap-fit element 11 are snapped together. After pressing the spring-loaded snap-fit component 9, the first snap-fit element 10 and the second snap-fit element 11 are disengaged. In one embodiment, the second snap-fit element 11 is a snap-fit connector, and the first snap-fit element 10 is a snap-fit groove. The spring-loaded snap-fit component 9 has a snap-fit groove, and the liquid outlet tube 3 has a snap-fit connector. When the liquid outlet tube 3 is stored in the storage groove 2, the snap-fit connector will accurately fall into the snap-fit groove. The shape of the opening 16 of the snap-fit groove is specially designed according to the elastic movement direction trajectory of the spring-loaded snap-fit component 9. The snap-fit opening 12 on the snap-fit connector and the snap-fit body 13 that is adapted to it in the snap-fit groove are tightly engaged. The two are locked together, firmly fixing the liquid outlet tube 3 in the storage groove 2, so that the liquid outlet tube 3 will not shake or fall out at will when not in use. When the user needs to pour oil using the dispensing tube 3, they gently press the spring-loaded locking element 9 with their finger. Under pressure, the spring-loaded locking element 9 overcomes the elastic force of the first elastic element 15 and slides smoothly down the slide rail 17 on the inner wall of the slide groove 14. As the spring-loaded locking element 9 slides down, the position of the locking groove changes, breaking the locking state between it and the locking connector, and the locking connector smoothly disengages from the locking groove. At this time, the second elastic element 20 (torsion spring), which was originally storing force, comes into play. The torsion spring is tightly fitted on the central shaft 19 of the rotating support block 4. After the restraint is released, it quickly releases the torque by virtue of the stored elastic potential energy, and drives the dispensing tube 3 to quickly rotate out of the receiving groove 2 with the central shaft 19 of the rotating support block 4 as the axis, generally rotating 45°-90°. Then the user can tilt the bottle to let the oil flow smoothly from the dispensing tube 3. The whole process is smooth and natural, and the operation is simple, providing great convenience to the user.
[0029] Furthermore, such as Figure 2 As shown, the storage slot 2 is meticulously designed at the top of the cover 1, providing a dedicated storage space for the dispensing tube 3. The dimensions of the storage slot 2 perfectly match the dispensing tube 3; its length is slightly longer than the dispensing tube 3, and its width and depth have been precisely calculated to ensure that the dispensing tube 3 will not be loose after being placed in the slot, nor will it be difficult to store due to insufficient space. Above the storage slot 2, a top cover 6 is specially provided. This top cover 6 not only serves a protective function but also has a certain aesthetic appeal. On one side of the top cover 6, a slot 7 is precisely cut to allow the dispensing tube 3 to freely enter and exit. The dimensions of the slot 7 have been precisely calculated to ensure that the dispensing tube 3 can enter and exit smoothly without excessive shaking. The edges of the slot 7 are chamfered to prevent scratching the surface of the dispensing tube 3 when it enters and exits.
[0030] Looking further, the storage slot 2 also features an opening. The position and size of this opening are perfectly positioned to allow the clamping connector of the liquid outlet tube 3 to pass smoothly through. The shape of the opening in the storage slot matches the clamping connector, ensuring accurate alignment when it passes through. The spring-loaded clamping component 9 is cleverly placed outside this opening. Its position and layout are closely integrated with the entire storage structure, together forming a stable and efficient storage system. The relative position of the spring-loaded clamping component 9 and the opening has been optimized through multiple tests to ensure accurate control of the separation and engagement of the clamping slot and the clamping connector when the spring-loaded clamping component 9 is pressed.
[0031] Furthermore, a rotating support block 4 is installed at one end of the dispensing tube 3. This rotating support block 4 is a key component that allows the dispensing tube 3 to rotate flexibly. The material of the rotating support block 4 can be high-strength engineering plastic, which has good wear resistance and toughness, and can maintain stable performance during long-term use. The second elastic element 20 (torsion spring) is tightly fitted onto the central shaft 19 of the rotating support block 4. The torsion spring is specially designed and processed to have a suitable elastic coefficient, which can quickly release the stored elastic potential energy after the dispensing tube 3 is unlocked, causing the dispensing tube 3 to rotate quickly out of the storage slot 2, providing great convenience for users. The elastic coefficient of the torsion spring is precisely adjusted according to the weight of the dispensing tube 3 and the force required for rotation, ensuring that the speed at which the dispensing tube 3 pops out is moderate, neither too fast to cause accidental injury, nor too slow to affect the user experience.
[0032] The cap 1 is tightly connected to the bottle, ensuring no oil leakage and providing a mounting space for other components. The dispensing tube 3 can rotate freely, making it easy to use when pouring oil for cooking, and can be stored in the storage compartment 2 after use, saving space and preventing dust. The return tube 5 can collect any dripping oil, preventing table stains and waste. The spring-loaded latch 9 and the first elastic element 15 together securely fix the dispensing tube 3 in the storage compartment 2, and can be unlocked by pressing the spring-loaded latch 9 when needed. The storage compartment 2 provides storage space for the dispensing tube 3, and the upper cover 6, when closed, can block dust and protect the dispensing tube 3. The rotating support block 4 allows the dispensing tube 3 to rotate, and the torsion spring will automatically pop the dispensing tube 3 out like a spring rebound after unlocking, making it very convenient to use. These components work together to create a fully functional and easy-to-use bottle cap.
[0033] The bottle body is made of high borosilicate glass, which has good heat resistance and can withstand large temperature changes without cracking, making it suitable for various cooking scenarios. The bottle mouth has external threads that can be screwed onto the cap body 1. The machining precision of the external threads on the bottle mouth is extremely high, and the tolerance of the fit between the external threads and the internal threads on the cap body 1 is strictly controlled to ensure a tight and stable connection between the two.
[0034] The internal threads of the bottle cap body 1 and the external threads of the bottle mouth are machined with great precision, with minimal errors in thread angle and spacing, ensuring a secure screw-on connection. A layer of food-grade sealing silicone can be applied to the screw-on area between the bottle mouth and the cap for even better sealing and to prevent oil leakage. This food-grade sealing silicone not only has excellent sealing performance but also meets food safety standards and will not contaminate the oil. In this way, the bottle cap not only seals the bottle well, ensuring oil quality, but also makes installation and removal convenient.
[0035] 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.
