Description

Technical Field

[0001] The utility model relates to a cover body of a liquid container, in particular to a bottle cap and an oil bottle with a recycling function. Background Art

[0002] Plastic bottle caps are widely used in the field of liquid containers. In daily life, there are various types of liquid containers with bottle cap designs. For example, oil bottles, soy sauce bottles, vinegar bottles, etc. are all equipped with spouted bottle caps on the liquid containers to achieve the pouring of liquids. The liquid pours out from the spout. However, there are many problems when using spouted bottle caps in the prior art. For example, the sealing performance is poor, and it is easy to leak when the container is tilted. To solve this defect, many solutions have been proposed in the prior art. For example, the patent document CN218752388U discloses an anti-leakage structure for a soy sauce bottle. It mainly includes a bottle body, a bottle cap, a spout, an auxiliary anti-leakage mechanism, an anti-leakage mechanism, and a sealing mechanism. The bottle cap is fixed on the top of the bottle body by means of threaded rotation, which can make the bottle cap more firmly fixed on the bottle body. The spout can pour out the soy sauce inside the bottle body. Then, the auxiliary sealing mechanism can initially prevent leakage of the spout. When in use, the spout can be opened through the anti-leakage mechanism. When it is not necessary to pour out soy sauce, the anti-leakage mechanism can re-seal the spout to prevent soy sauce from leaking out from the spout. The sealing mechanism is fixedly arranged between the bottle cap and the bottle body. When the bottle cap is fixed on the bottle body by threaded rotation, the bottle cap can squeeze the sealing mechanism to prevent soy sauce from leaking through the interface between the bottle cap and the bottle body. This design has a complex structure, relatively high cost, and mostly relies on spring structures to achieve anti-leakage, which is prone to failure, has a short service life, and is inconvenient to operate. Moreover, there will still be residual liquid at the spout after pouring out, and the residual liquid drips along the spout. In the long term, on the one hand, it will cause waste of liquid, and on the other hand, it will also cause hygienic problems. Summary of the Utility Model

[0003] This application proposes a bottle cap and an oil bottle with a recycling function, which solves the defects in the prior art such as the complex anti-leakage design and high cost of the spouted structure of liquid containers such as oil bottles, and at the same time effectively solves the defect that the residue at the spout cannot be recycled or is inconvenient to recycle.

Detailed implementation manners

[0022] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer, the following further details the present utility model in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0023] The present utility model provides a bottle cap and an oil bottle with a recycling function, as Figure 1 、 2 shown. The bottle cap mainly includes three major parts: a cap body 1, a bottle nozzle 5 and a top seat 14. The cap body 1 is a circular cap that is universal for the bottle mouth. The inner side of the cap body 1 has threads, and the cap body 1 can be fixed on the bottle mouth through the threads. The bottle nozzle 5 is arranged on the cap body 1 and is communicated with the cap body 1. Liquid can be poured out through the bottle nozzle 5. The top seat 14 is prominently arranged on the upper part of the cap body 1.

[0024] Specifically, in combination with the attached Figure 1 、 2As shown in FIGS. 3, in this embodiment, an installation position 2 is provided on the outer side of the cover body 1. The installation position 2 is specifically arranged on the upper part of the cover body 1. The bottle mouth 5 is a hollow rod body. One end of the bottle mouth 5 is rotatably installed in the installation position 2, so that the bottle mouth 5 can rotate freely in the installation position 2. An liquid outlet 3 and a liquid return port 4 are respectively arranged in the installation position 2. Both the liquid outlet 3 and the liquid return port 4 communicate with the inside of the bottle. And the bottle mouth 5 further includes a liquid outlet channel 6 and a liquid return channel 7. The liquid outlet channel 6 and the liquid return channel 7 penetrate through both ends of the bottle mouth 5. The liquid outlet channel 6 is communicated with the liquid outlet 3 for pouring out the liquid in the bottle. One end of the liquid return channel 7 is a return port 8. The return port 8 is arranged on the liquid outflow side of the liquid outlet channel 6. The other end of the liquid return channel 7 is communicated with the liquid outlet channel 6. The liquid return port 4 is communicated with the liquid return channel 7 for the liquid at the bottle mouth 5 to flow back into the bottle. By rotating the bottle mouth 5, the liquid outlet 3 is communicated with the liquid outlet channel 6 to pour out the liquid, or the liquid return port 4 is communicated with the liquid return channel 7 to make the liquid flow back. In other traditional implementable solutions, one end of the bottle mouth can also be fixedly arranged in the installation position. The liquid outlet channel is communicated with the liquid outlet. One end of the liquid return channel is a return port. The other end of the liquid return channel communicates with the inside of the cover body. And the return port is arranged on the liquid outflow side of the liquid outlet channel. The liquid return channel 7 communicates with the inside of the bottle cap for the liquid at the bottle mouth 5 to flow back into the bottle.

[0025] Based on this embodiment, when the bottle mouth is outside the storage groove, the liquid outlet is relatively connected to the first opening to realize the pouring of the liquid. After use, the liquid droplets at the end of the liquid outlet channel can enter the liquid return channel along the return port, and finally flow into the liquid outlet channel. Then the bottle mouth is returned to the storage groove, and the liquid droplets can be collected from the liquid return channel. This can not only simplify the bottle mouth structure of the liquid container, making the anti-leakage design simpler and of lower cost, but also effectively solve the problem that the residue at the bottle mouth cannot be recycled or is inconvenient to recycle.

[0026] In this embodiment, in combination with the attached Figure 4 、 5As shown, the installation position 2 is set as an arc-shaped groove. One end of the bottle nozzle 5 is provided with a sphere 9. The sphere 9 is rotatably arranged in the installation position 2 through a rotating shaft 19. By rotating the sphere 9, the liquid outlet channel 6 is communicated with the liquid outlet 3 or the liquid return port 4 is communicated with the liquid return channel 7. At the same time, in order to ensure that the fitting clearance between the installation position 2 and the sphere 9 is small enough to avoid the situation of liquid overflowing from the gap between the installation position 2 and the sphere 9, the material of the sphere 9 can be selected to be elastic, such as silicone. In this way, the contact surface between the installation position 2 and the sphere 9 can be sealed by elastic extrusion. A flexible tube body can also be used to connect the liquid outlet channel 6 with the liquid outlet 3, and a flexible tube body is used to connect the liquid return port 4 with the liquid return channel 7. For example, a section of flexible pipeline extends from the ends of the liquid outlet channel 6 and the liquid return channel 7. When the pipeline of the liquid outlet channel 6 extends into the liquid outlet 3 when the sphere 9 rotates, the liquid outlet channel 6 is communicated with the inside of the bottle. When the sphere 9 continues to rotate until the pipeline of the liquid outlet channel 6 is squeezed at the gap between the sphere 9 and the installation position 2, the liquid outlet channel 6 is closed. The principle of the liquid return channel 7 is the same as that of the liquid outlet channel 6 and will not be elaborated here.

[0027] In addition, in this embodiment, the sphere 9 can also be set to be hollow, and the interior of the sphere 9 is divided into two independent chambers, namely the liquid outlet chamber 10 and the liquid return chamber 11. The liquid outlet chamber 10 is communicated with the liquid outlet channel 6, and the liquid outlet chamber 10 is also provided with a first opening 12 that can communicate with the liquid outlet 3. The liquid return chamber 11 is communicated with the liquid return channel 7, and the liquid return chamber 11 is also provided with a second opening 13 that can communicate with the liquid return port 4. The communication with the liquid outlet 3 is achieved through the first opening 12, and the communication with the liquid return port 4 is achieved through the second opening 13. In this way, there is no need to additionally set up a complex flow path, and the liquid return channel 7 and the liquid outlet channel 6 are integrally arranged, making the bottle cap structure more compact.

[0028] Furthermore, a filter screen can be set on the liquid outlet 3 and / or the liquid return port 4 in this application. By setting the filter screen, impurities can be effectively blocked from entering and leaving, ensuring the smoothness of the flow channel.

[0029] It should be emphasized that in other embodiments, the sphere 9 can also be rotatably nested in the installation position 2. The notch of the installation position 2 is smaller than the diameter of the sphere 9, so that the sphere 9 can freely rotate in the installation position 2 and the degree of freedom is not limited. The bottle nozzle 5 extends out from the notch of the installation position 2. In this way, the rotational connection between the bottle nozzle 5 and the installation position 2 can also be achieved.

[0030] Furthermore, a storage groove 15 is also provided on one side of the top seat 14 in this application. The storage groove 15 is vertically arranged and is adapted to the shape of the bottle nozzle 5. By setting the storage groove 15, the bottle nozzle 5 can be received in the storage groove 15 when the oil is not being poured. At the same time, a dust-proof cover 16 is also provided at the top of the storage groove 15 to prevent the bottle nozzle 5 from being exposed to accumulate dust and sundries from entering the bottle nozzle 5.

[0031] Furthermore, the dust cover 16 can be fixedly arranged at the top end of the storage groove 15, or can be arranged on the top of the storage groove 15 in an openable and closable manner. The so-called openable and closable arrangement means that the dust cover 16 can perform the functions of opening and closing. By such an arrangement, it is more convenient to take out the nozzle 5 located in the storage groove 15. In a specific embodiment, the opening and closing of the dust cover 16 is realized by a push-pull arrangement. For example, a horizontal chute 17 is provided at the top of the top seat 14, and the dust cover 16 is slidably arranged in the chute 17, and the storage groove 15 is arranged in the bottom direction of the chute 17, so that the opening and closing of the dust cover 16 can be realized by pushing and pulling it. In other embodiments, the dust cover 16 can also be arranged in a form of flipping open and closing. Since this is prior art, it will not be elaborated here.

[0032] Further, an air hole 18 is also provided on the top seat 14, and the air hole 18 is communicated with the inside of the cover body 1 to realize the normal pouring of the liquid.

[0033] When in use, when the nozzle 5 is outside the storage groove 15, the liquid outlet 3 is oppositely communicated with the first opening 12 to realize the pouring of the liquid. After use, the liquid drops at the end of the liquid outlet channel 6 can flow into the liquid return channel 7 along the liquid return port 8, and then the nozzle 5 is returned to the storage groove 15. At this time, the liquid return port 4 is oppositely communicated with the second opening 13, and the liquid drops can smoothly enter the bottle through the liquid return port 4 from the liquid return channel 7 for collection. In this way, the structure of the liquid container with the nozzle 5 can be simplified, the anti-leakage design can be made more simple and low-cost, and at the same time, the problem that the residue of the nozzle 5 cannot be recycled or is inconvenient to recycle is effectively solved.

[0034] The present utility model also discloses an oil bottle, and the oil bottle includes the above-mentioned bottle cap.

[0035] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
