[0006] The lid has an assembly groove at the bottom, and an inner sealing strip is embedded in the assembly groove. The groove of the inner sealing strip has a first sealing boss at the bottom of the groove, a second sealing boss and a third sealing boss at the wall of the groove. The first sealing boss is used to abut against the top wall of the mating part at the top of the barrel, and the second sealing boss and the third sealing boss are used to abut against the side wall of the mating part at the top of the barrel, respectively.

[0007] The cover includes an outer edge buckle portion, which is used to limit the connection with the fastening part of the mating part.

[0008] In some embodiments, the mating gap between the first sealing boss and the outer edge buckle is smaller than the distance between the top wall of the mating part and the buckle.

[0009] In some embodiments, the mating surfaces of the second sealing boss and the third sealing boss are inclined surfaces, and they are interference-fitted with the mating part.

[0029] Reference Figures 1 to 4 In a first aspect, this embodiment provides a sealing cap for sealing a barrel 20, comprising:

[0030] The cover 10 has an assembly groove 11 at the bottom, and an inner sealing strip 30 is embedded in the assembly groove 11. The groove of the inner sealing strip 30 has a first sealing boss 31 located at the bottom of the groove, a second sealing boss 32 located on the groove wall, and a third sealing boss 33 located on the groove wall. When the cover 10 is closed on the barrel 20, the mating part 21 at the top of the barrel 20 is inserted into the groove of the inner sealing strip 30. Specifically, the first sealing boss 31 is used to abut against the top wall of the mating part 21 at the top of the barrel 20, and the second sealing boss 32 and the third sealing boss 33 are respectively used to abut against the side wall of the mating part 21 at the top of the barrel 20. When the cover 10 is closed on the barrel 20, these sealing bosses form multiple sealing contacts with the barrel 20 from three mating surfaces.

[0031] The lid 10 includes an outer edge buckle 12, which is used to limit the connection with the buckle 22 of the mating part 21. By limiting the connection between the outer edge buckle 12 and the buckle 22 of the mating part 21, the lid 10 is firmly fixed on the barrel 20 to prevent loosening.

[0032] Specifically, when the cap 10 is placed on the barrel 20, the first sealing protrusion 31 of the inner sealing strip 30 first abuts against the top wall of the mating part 21 at the top of the barrel 20, forming the first sealing barrier. Subsequently, the second sealing protrusion 32 and the third sealing protrusion 33 respectively make an interference fit with the side wall of the mating part 21, forming the second and third sealing barriers. Finally, the outer edge buckle 12 is locked and connected to the buckle 22 of the mating part 21, ensuring that the cap 10 will not loosen, thereby achieving a multi-seal effect. This embodiment effectively improves the sealing performance through a multi-seal structure, preventing oil leakage during transportation and storage, and ensuring the safety and environmental friendliness of the oil.

[0033] Combination Figure 2 and Figure 7 In one embodiment, the fitting gap between the first sealing boss 31 and the outer edge buckle 12 is smaller than the distance between the top wall of the fitting part 21 and the buckle 22. When the cover 10 is fully closed, under the pre-tightening action between the outer edge buckle 12 and the buckle 22 of the fitting part 21, the first sealing boss 31 and the top wall of the fitting part 21 form a tight contact, thereby making the seal between the cover 10 and the barrel 20 tighter and effectively preventing oil leakage. At the same time, the optimized design of the fitting gap avoids the loosening of the cover 10, further ensuring the reliability and durability of the seal.

[0034] Combination Figure 2 In one embodiment, the mating surfaces of the second sealing boss 32 and the third sealing boss 33 are beveled and are interference-fitted with the mating part 21. This beveled design allows the sealing bosses to gradually press against the side wall of the mating part 21 when the cover 10 is closed, forming an interference fit and further enhancing the sealing effect. The interference fit of the beveled surface not only improves the sealing performance but also increases the stability of the connection, effectively preventing seal failure and thus ensuring the safe storage and transportation of oil.

[0035] Preferably, the inner seal 30 is made of polyethylene, a material with good wear resistance, capable of withstanding friction and impact during daily use and maintaining a good sealing effect. Simultaneously, PE material has good high and low temperature resistance, maintaining good elasticity and sealing effect in high and low temperature environments, without softening or deforming due to temperature increases, thus ensuring the reliability of the seal. Furthermore, PE seals also have excellent chemical stability, resisting the erosion of various chemicals and ensuring that they will not react with loaded oils during long-term use.

[0036] Combination Figure 3 and Figure 4 In one embodiment, the top surface of the cover 10 is also provided with an oil outlet component 40, which includes an inner cover 41 and an outer cover 42.

[0037] The inner cover 41 is fixed to the clearance hole on the top surface of the cover body 10, and the inner cover 41 is provided with a tear-out opening 43;

[0038] The outer cover 42 includes a fixing part 44 and a protective part 45. The fixing part 44 is connected to the top of the inner cover 41, and the protective part 45 is connected to the fixing part 44 through a number of bridge points 46.

[0039] When oil is needed, the user only needs to pull the protective part 45 to break the bridge point 46 between the protective part 45 and the fixed part 44 and unscrew it. Then, the tear-off opening 43 of the inner cover 41 is pulled off, and the oil in the container 20 can be poured out for use. This oil outlet component 40 design not only makes it easy for users to use, but also avoids accidental leakage and pollution of oil, improving the convenience and cleanliness of use.

[0040] Preferably, the oil outlet component 40 and the cap 10 are integrally injection molded; the integral molding process ensures a tight connection between the oil outlet component 40 and the cap 10, avoiding the problems of weak connection and poor sealing that may occur with traditional assembly processes. Through integral injection molding, the product structure is more compact, the sealing performance is better, and the production process is also simplified, improving production efficiency and product quality.

[0041] Combination Figures 5 to 7 Secondly, this embodiment provides an oil container, including a container body 20 and a sealing cap as described above. By using the sealing cap 10 designed above, the oil container can maintain good sealing performance during storage and transportation, preventing oil leakage and ensuring the safety and environmental friendliness of the oil. At the same time, the multiple sealing structure and one-piece molding process of the sealing cap 10 improve the reliability and durability of the product, meeting the sealing requirements in various usage scenarios.

[0042] In summary, compared with the prior art, the above embodiments provide a sealing cap and an oil container. Through the inner sealing strip 30 set in the assembly groove 11, the multiple sealing protrusions of the inner sealing strip 30 make multiple sealing contacts with the top wall and side wall of the mating part 21 at the top of the container 20. Combined with the outer edge buckle part 12 of the cap 10 and the buckle 22 of the mating part 21 for limiting connection, multiple sealing barriers are formed, thereby significantly improving the sealing performance of the sealing cap 10, preventing oil leakage during transportation and storage, and ensuring the safety and environmental protection of the oil.

[0043] The inner seal 30 is made of polyethylene, which has good elasticity and durability, further enhancing the sealing effect and service life. The overall structure is manufactured through a one-piece injection molding process, ensuring a tight fit between all components and improving the reliability and stability of the product.

[0044] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
