[0025] Whenever possible, the various aspects and features described and shown in the specification can be applied individually, and these individual aspects can serve as the subject of a divisional application.

[0026] See Figures 1-10 This is one embodiment of a quick-fill refueling bottle proposed in this utility model. A quick-fill refueling bottle 100 includes: a bottle body 10 and a bottle cap 20. The bottle body 10 has a cavity 11 for holding oil, and the bottle cap 20 is detachably installed on the bottle body 10. The bottle cap 20 has a cap cylinder 21 fixedly installed to the bottle body 10, and an openable upper cap 22 located at the upper end of the cap cylinder 21. A quick-fill refueling channel 212 is provided inside the cap cylinder 21, with a lower port 2121 communicating with the cavity 11 and an upper port 2122 communicating with the outside. By providing the refueling channel 212 inside the cap cylinder 21, the user only needs to open the upper cap to inject liquid from the upper port of the refueling channel 212, eliminating the cumbersome steps of disassembling and reinstalling the traditional bottle cap, simplifying the refueling process, and improving operational efficiency. The openable design of the top cover 22 ensures convenient operation during refueling and can also close the upper port of the refueling channel 212 when not in use. Combined with the sealing structure of the cap tube 21 and the bottle body 10, it effectively prevents liquid leakage or evaporation and is suitable for storing liquids that are easily oxidized or volatile, such as edible oil and soy sauce.

[0027] In some embodiments of this application, the refueling channel 212 has a funnel-shaped cavity 2123 with a gradually decreasing cross-sectional size in the downward direction, and a refueling chamber 2124 extending upward from the upper end of the funnel-shaped cavity 2123. A partition 2125 is provided inside the refueling channel 212, located below the refueling chamber 2124, and the funnel-shaped cavity 2123 is formed on the partition 2125. The funnel-shaped cavity 2123, with its gradually decreasing cross-section in the downward direction, forms a funnel-shaped structure, which guides and converges the injected liquid, allowing it to flow quickly and accurately into the bottle cavity, reducing liquid overflow caused by excessive flow rate or angular deviation during refueling; and reducing dead zones for liquid residue. The refueling chamber 2124 extends upward from the upper end of the funnel-shaped cavity 2123, providing a buffer space for the injected liquid and reducing splashing when the liquid directly impacts the funnel-shaped cavity.

[0028] In some embodiments of this application, the refueling channel 212 further includes a lower oil chamber 2126 located below the funnel-shaped cavity 2123, and a partition 2125 located between the refueling cavity 2124 and the lower oil chamber 2126. The funnel-shaped cavity 2123 connects the refueling cavity 2124 and the lower oil chamber 2126. The lower oil chamber 2126 is located below the funnel-shaped cavity 2123 and is separated from the refueling cavity 2124 by the funnel-shaped cavity and the partition 2125. The liquid is first initially buffered by the refueling cavity, then converged and slowed down by the funnel-shaped cavity, and finally smoothly transitions into the bottle cavity through the lower oil chamber 2126, completely avoiding splashing caused by excessive flow rate, which is especially suitable for liquids with large pouring volume or high viscosity. The baffle 2125 is located between the filling chamber 2124 and the lower oil chamber 2126. Its funnel-shaped cavity 2123 forms a one-way flow structure: liquid can flow from the filling chamber 2124 into the lower oil chamber 2126 through the funnel-shaped cavity 2123. When the bottle is tilted or shaken, the liquid in the lower oil chamber 2126 is difficult to flow back to the filling chamber 2124 through the funnel-shaped cavity 2123, which reduces channel contamination caused by liquid backflow.

[0029] In some other embodiments of this application, the lower oil cavity 2126 may not be provided, and the partition 2025 may be directly provided at the lower port 2121; the partition 2125 and the bucket-shaped cavity 2123 may also not be provided.

[0030] In some embodiments of this application, the bottle cap 20 also has an oil outlet structure 23 disposed within the cap cylinder 21, and the oil outlet channel 212 is disposed in the middle or front part of the cap cylinder 21. The oil outlet structure 23 has an oil nozzle 231 located in front of the oil outlet channel 212, an oil spray pipe 232 located behind the oil outlet channel 212, and a connecting pipe 233 connecting the oil spray pipe 232 and the oil nozzle 231. During refueling, the liquid is directly injected into the bottle body 10 through the middle / front channel, and during oil dispensing, the liquid is sprayed out from the oil nozzle through the rear oil spray pipe and the connecting pipe, ensuring that the refueling and dispensing processes do not interfere with each other, thus improving hygiene. The oil outlet channel 212 is located in the middle or front, in a conspicuous position with ample operating space, allowing users to complete refueling without adjusting their grip, making it particularly suitable for one-handed operation and improving ease of use.

[0031] In some embodiments of this application, the cap 21 has a cylindrical body 210, a sealing plate 211 that divides the space inside the cylindrical body 210 vertically, and a lower port 2121 formed on the sealing plate 211. The cylindrical body 210, the sealing plate 211, and the refueling channel 212 are integrally formed, with the lower end of the refueling channel 212 connected to the lower port 2121. The sealing plate 211 divides the space inside the cylindrical body 210 vertically, forming an independent upper operating area with a refueling channel and an oil outlet structure; and a lower connecting area that connects to the bottle cavity, achieving a detachable seal through a threaded structure; effectively preventing the evaporation of liquid inside the bottle or the upward movement of odors. The refueling channel 212 directly connects to the cavity of the bottle 10 through the lower port 2121, forming a straight refueling path, avoiding the corner and gap residue problems caused by traditional multi-part connections. The sealing plate 211 provides lateral support to the cylinder 210, enhancing the overall structural strength of the cover cylinder 21 and preventing cylinder deformation caused by frequent refueling or tilting. The refueling channel 212 is directly connected to the sealing plate 211, reducing the connection gap and dispersing the impact force during refueling to the sealing plate, which in turn is transmitted to the entire cover cylinder, improving its long-term durability.

[0032] In some embodiments of this application, the upper cover 22 has a cover body 221 covering the upper end of the cover cylinder 21, and a sealing plug 222 extending downward along the cover body 221 and into the refueling channel 212. An annular sealing strip 223 is provided on the outer side of the sealing plug 222. The sealing plug 222 extends into the refueling channel 212, and, in conjunction with the outer annular sealing strip 223, fits tightly against the inner wall of the refueling channel 212, improving sealing performance. This effectively prevents leakage of liquid inside the bottle due to tilting or shaking, while also blocking the leakage of volatile liquid odors, keeping the kitchen environment fresh. The design of the sealing plug 222 extending into the channel can adapt to the shape of the inner wall of the refueling channel 212. Even if there are slight dimensional deviations in the channel, the sealing strip 223 can fill the gaps through elastic deformation, ensuring consistent sealing performance at different locations. The sealing strip 223 contacts and seals against the inner wall of the refueling chamber 2124. The cover 221 and the sealing plug 222 of the top cover 22 are integrated. When opening, simply lift the top cover 22 to simultaneously pull out the sealing plug 222. When closing, the sealing plug 222 naturally falls into the refueling channel 212 and automatically fits through the sealing strip 223 without any additional adjustment.

[0033] In some embodiments of this application, the sealing strip 223 achieves a seal between the sealing plug 222 and the refueling channel 212, and the upper cover 22 is installed by extending into the refueling channel 212 through the sealing plug 222. An annular groove is formed on the outer side of the sealing plug 222, and the sealing plug 222 is installed within the groove. The annular groove on the outer side of the sealing plug 222 provides precise installation positioning for the sealing strip 223, making it less likely to fall off or shift during long-term use. Compared to the traditional structure of directly fitting onto a smooth surface, the groove provides mechanical restraint, ensuring that the sealing strip 223 always remains in contact with the inner wall of the refueling channel 212, maintaining a stable sealing effect. After the sealing strip 223 is inserted into the groove, its outer side protrudes from the surface of the sealing plug 222. When the sealing plug 222 is inserted into the refueling channel, the inner wall of the refueling channel 212 will compress the sealing strip 223, causing the sealing strip 223 to undergo elastic deformation in the groove, increasing the contact pressure and contact area with the inner wall of the channel; it can effectively fill tiny gaps, and even if there are slight unevennesses in the inner wall of the channel, it can ensure tight sealing and reduce the risk of leakage.

[0034] In some embodiments of this application, the bottle cap 20 further includes an inner cap 24 covering the upper side of the cap cylinder 21. The inner cap 24 is located below the upper cap 22, and an allowance opening 241 matching the refueling channel 212 is provided on the inner cap 24. The allowance opening 241 on the inner cap 24 precisely matches the refueling channel 212, providing a through space for the refueling channel 212 without obstructing the refueling operation. At the same time, the remaining part of the inner cap 24 closes the non-channel area on the upper side of the cap cylinder 21, preventing dust and impurities from falling into the gap between the cap cylinder 21 and the upper cap 22, thus keeping the inside of the cap cylinder 21 clean. After the upper cap 22 is opened, the inner cap 24 and the refueling channel 212 extending into the allowance opening 241 are visible.

[0035] In some embodiments of this application, the refueling channel 212 is located within the clearance opening 241, and a reinforcing edge 242 extends downward along the clearance opening 241. The inner cover 24 is located inside the cap cylinder 21, and an extending edge 243 extends downward at the edge of the inner cover 24. The refueling channel 212 is located within the clearance opening 241, forming a nested fit. The reinforcing edge 242 extends downward and fits against the outer wall of the refueling channel 212, enhancing the connection strength between the inner cover 24 and the refueling channel 212 and reducing displacement of the inner cover 24 due to vibration or collision during use. Simultaneously, the extending edge 243 of the inner cover 24 extends downward and fits against the inner side of the cap cylinder 21, further securing the inner cover 24 within the cap cylinder 21, making the assembly of the bottle cap 20 components more stable. The reinforcing edge 242 fits tightly against the outer wall of the refueling channel 212, increasing the contact area between them, increasing the firmness of the inner cover 24 after installation, and increasing support for the upper end of the refueling channel 212. The reinforcing edge 242 extends downwards along the clearance opening, dispersing the pressure on the inner cover 24 and preventing deformation due to excessive local stress. The extending edge 243 strengthens the structural strength of the inner cover 24's edges, reducing edge warping caused by frequent disassembly or collisions and extending the service life of the inner cover 24. The nesting fit between the reinforcing edge 242 and the refueling channel 212, and the fit between the extending edge 243 and the inner side of the cover cylinder 21, provide a clear positioning reference for the installation of the inner cover 24, enabling the inner cover 24 to be quickly aligned during assembly, reducing production errors, and improving assembly efficiency and consistency.

[0036] In some embodiments of this application, a locking and fixing structure is provided between the inner side of the cover cylinder 21 and the inner cover 24. The locking and fixing structure consists of a groove 213 on the cover cylinder 21 and a protrusion 244 on the inner cover 24. The groove 213 is located on the inner circumferential side of the cylinder 210, and the protrusion 244 is located on the outer circumferential side of the cover 221. The groove 213 on the inner circumferential side of the cover cylinder 21 and the protrusion 244 on the outer circumferential side of the inner cover 24 form a full circumferential locking, which can evenly distribute the force on the inner cover 24, so that the inner cover 24 is firmly fixed to the inner side of the cover cylinder 21, and avoid the inner cover 24 from loosening or falling off due to vibration or tilting during use. During assembly, simply align the inner cover 24 with the inner side of the cover cylinder 21 and press it down, and the protrusion 244 will elastically engage with the groove 213 to complete the fixing.

[0037] In other embodiments of this application, the locking structure may also be a locking protrusion on the cover cylinder 21 and a locking groove on the inner cover 24.

[0038] In some embodiments of this application, a vertically extending support rib 214 is provided inside the cap cylinder 21, and a receiving groove 245 is provided on the inner cap 24 to accommodate the support rib 214. The vertically extending support rib 214 inside the cap cylinder 21 can enhance the longitudinal structural strength of the cylinder 210 and reduce the deformation of the cylinder 210 caused by the weight of the liquid inside the bottle, external pressure, or temperature changes. The receiving groove 245 of the inner cap 24 fits into the support rib 214, further dispersing the force through the rigid cooperation between the two, so that the cap cylinder and the inner cap form a support, improving the overall impact resistance. The fitting cooperation between the support rib 214 and the receiving groove 245 provides an additional positioning reference for the installation of the inner cap 24 inside the cap cylinder 21. With the circumferential fixing of the slot 213 and the protrusion 244, the radial movement and circumferential rotation of the inner cap 24 can be restricted, ensuring that the clearance opening 241 of the inner cap 24 is always precisely aligned with the refueling channel 212, avoiding refueling obstruction or sealing failure due to the misalignment of the inner cap 24.

[0039] In some embodiments of this application, the cover cylinder 21 is provided with a handle 215 connected to the cylinder body 210, and the oil outlet structure 23 also has a pressure rod 234, which realizes oil spraying from the oil injector 231 by pressing down the oil injection pipe 232.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
