Description

Technical Field

[0001] This utility model relates to the field of food packaging technology, specifically to a leak-proof edible oil bottle cap. Background Technology

[0002] Currently, drinking water and edible oils such as vinegar, soy sauce, sesame oil, and peanut oil in the market are often bottled. During the use of edible oil, traditional bottle caps often have defects in their sealing structure design, resulting in problems such as oil backflow and leakage when poured, and poor sealing at the connection between the cap and the bottle mouth leading to oil evaporation or the intrusion of external impurities. This not only causes waste and affects the user experience, but may also pollute the storage environment.

[0003] When using existing cooking oil bottle caps, in household use, users often repackage large bottles of cooking oil into smaller bottles or containers. Most existing bottle caps are designed so that the spout can be opened by pressing with a finger, allowing the bottle to be tilted to pour out the cooking oil. However, after use, younger children may knock over or play with the bottle, causing the cooking oil to leak out and resulting in waste.

[0004] To address this issue, we designed a leak-proof cooking oil bottle cap. Utility Model Content

[0005] The purpose of this invention is to provide a leak-proof edible oil bottle cap to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides a leak-proof edible oil bottle cap, including a bottle cap base and a bottle cap top connected to the top of the bottle cap base. A mounting base is fixedly connected to one side of the bottle cap base, and a fixing block is fixedly installed on the top of the mounting base. An abutment block is slidably connected inside the fixing block, and a slider is provided below the abutment block. A slot is opened on one side of the fixing block, and the slider is slidably inserted into the slot. A telescopic spring is fixedly connected to one side of the slider, and a handle is fixedly connected to one side of the telescopic spring.

[0007] Furthermore, a mounting groove is provided on one side of the slot, and a telescopic spring is fixedly connected to one side of the inner wall of the mounting groove. The other end of the telescopic spring is fixedly connected to the rectangular block.

[0008] Furthermore, a lever is fixedly connected to one side of the abutting block, and a sliding groove is provided on one side of the fixed block, with the lever slidably connected to the sliding groove.

[0009] Furthermore, the number of the telescopic springs is set to two, and the two telescopic springs are symmetrically arranged on both sides of the slider with the slider as the center.

[0010] Furthermore, a toggle is fixedly connected to one side of the bottle cap top, and a rotating shaft is inserted into the top of the fixing block. The toggle is movably connected to the fixing block through the rotating shaft.

[0011] Furthermore, a spout is fixedly installed on the top of the bottle cap base.

[0012] Furthermore, a guide groove is provided at one end of the fixing block, and the abutting block is slidably connected to the guide groove.

[0013] Furthermore, the handle is U-shaped, and the outer side of the handle has an integrally formed anti-slip texture.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: After using the oil can, the top of the oil can cap is limited, the handle is pulled, and the slider slides in the slot on one side of the fixed block. The slot moves from the through guide groove to not contacting the guide groove. At this time, the toggle block is slid to the top of the groove, and then the hand holding the handle is released. At this time, the telescopic spring returns to its original position and drives the rectangular block to slide inside the fixed block, so that the slider passes through the slot again through the guide groove, fixing the abutment block and preventing the toggle part from being touched by the outside and easily rotating downward, causing the top of the cap to open and the oil to leak out.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides a technical solution: it includes a bottle cap base 1 and a bottle cap top 2 connected to the top of the bottle cap base 1. A mounting base 3 is fixedly connected to one side of the bottle cap base 1. A fixing block 6 is fixedly installed on the top of the mounting base 3. An abutment block 7 is slidably connected inside the fixing block 6. A slider 9 is provided below the abutment block 7. A slot 14 is opened on one side of the fixing block 6. The slider 9 is slidably inserted into the slot 14. A telescopic spring 15 is fixedly connected to one side of the slider 9. A handle 12 is fixedly connected to one side of the telescopic spring 15.

[0023] It should be noted that the bottom of the cap 2 is threaded, and the cap 2 can be screwed onto the top of the oil bottle. The inside of the cap 2 is a spout, which can communicate with the inside of the oil bottle containing the cooking oil, making it convenient to use the cooking oil. When it is necessary to pour the oil, hold the bottle handle 12 and open the cap 2 to let the cooking oil flow out from the spout. This is existing technology, so it will not be described in detail here.

[0024] In practice, to prevent children from knocking over the oil bottle and causing cooking oil to leak out, the top 2 of the bottle cap can be stopped after use. When using the oil bottle, the abutment block 7 is located at the bottom of the guide groove 10 and contacts the mounting base 3. After use, pull the handle 12 to make the slider 9 slide in the slot 14 on one side of the fixed block 6. The slot 14 moves from penetrating the guide groove 10 to not contacting the guide groove 10. At this time, slide the toggle block 8 to the top of the slide groove 11, and then release the hand holding the handle 12. At this time, the telescopic spring 15 returns to its original state from the stretched state, causing the rectangular block 16 to slide inside the fixed block 6, so that the slider 9 passes through the slot 14 again through the guide groove 10. The abutment block 7 is fixed at the bottom. The top end of the abutment block 7 abuts against the bottom of the inner wall of the toggle member 4, which can prevent the toggle member 4 from rotating downward, thereby opening the top 2 of the bottle cap and causing oil to leak out.

[0025] See Figure 5 A mounting groove 13 is provided on one side of the slot 14. A telescopic spring 15 is fixedly connected to one side of the inner wall of the mounting groove 13. The other end of the telescopic spring 15 is fixedly connected to the rectangular block 16. There are two telescopic springs 15, which are symmetrically arranged on both sides of the slider 9 with the slider 9 as the center.

[0026] By setting two telescopic springs 15, one end of each spring 15 is connected to the inner wall of the mounting groove 13, and the other end is connected to a rectangular block 16. The rectangular block 16 is slidably disposed on one side inside the fixed block 6. When the handle 12 is pulled by the rectangular block 16, the telescopic spring 15 is stretched. When the handle 12 is no longer pulled by the hand, the telescopic spring 15 retracts and resets, causing the rectangular block 16 to reset. There are two telescopic springs 15, symmetrically disposed on both sides of the slider 9, which helps to improve the stability of the sliding of the rectangular block 16 and the slider 9.

[0027] See Figure 3 A toggle block 8 is fixedly connected to one side of the contact block 7, and a sliding groove 11 is provided on one side of the fixed block 6. The toggle block 8 is slidably connected to the sliding groove 11. A guide groove 10 is provided at one end of the fixed block 6, and the contact block 7 is slidably connected to the guide groove 10.

[0028] By setting a lever 8, one end of the lever 8 protrudes out of the outside of the slide groove 11, making it easy for the user to move the lever 8 within the slide groove 11, thus improving the convenience of moving the contact block 7. The lever 8 is set perpendicular to one side of the contact block 7.

[0029] See Figure 1 and Figure 2 A toggle 4 is fixedly connected to one side of the bottle cap top 2, and a rotating shaft 5 is inserted into the top of the fixing block 6. The toggle 4 is movably connected to the fixing block 6 through the rotating shaft 5, and a spout is fixedly installed on the top of the bottle cap base 1.

[0030] By setting a toggle 4, the end of the toggle 4 away from the top of the bottle cap 2 is provided with a rounded corner, so that the user can press the tail of the toggle 4 with his finger, thereby causing the toggle 4 to rotate around the pivot 5, and the top of the bottle cap 2 to separate from the bottle cap base 1, so that the cooking oil can be poured out from the spout by tilting the oil bottle.

[0031] See Figure 5 The handle 12 is shaped like a "U" and has an integrally formed anti-slip texture on the outside.

[0032] By setting the handle 12, the shape of the handle 12 is set as "U" and the outer side of the handle 12 is provided with an integrally formed anti-slip texture, so that parents can hold the handle 12, put their fingers into the handle 12, pull the handle 12 to drive the rectangular block 16 to move, so that the slider 9 slides inside the fixed block 6.

[0033] Working principle: To prevent children from knocking over the oil bottle and causing oil to leak out, the top 2 of the bottle cap can be stopped after use. When using the oil bottle, the contact block 7 is located at the bottom of the guide groove 10 and contacts the mounting base 3. After use, pull the handle 12 to make the slider 9 slide in the slot 14 on one side of the fixed block 6. The slot 14 moves from penetrating the guide groove 10 to not contacting the guide groove 10. At this time, slide the toggle block 8 to the top of the slide groove 11, and then release the hand holding the handle 12. At this time, the telescopic spring 15 returns to its original state from the stretched state, causing the rectangular block 16 to slide inside the fixed block 6, so that the slider 9 passes through the slot 14 again through the guide groove 10. The contact block 7 is fixed at the bottom. The top end of the contact block 7 abuts against the bottom of the inner wall of the toggle member 4, which can prevent the toggle member 4 from rotating downward, thereby opening the top 2 of the bottle cap and causing oil to leak out.

[0034] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
