[0029] 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. Example

[0030] See Figures 1-10 This is the first embodiment of a rotary-opening oil bottle proposed in this utility model. The rotary-opening oil bottle 100 includes: a bottle body 10, a fastening sleeve 20, and a cap module 30. The fastening sleeve 20 has a fastening cylinder 21 that is detachably and sealingly fastened to the bottle body 10, and an upper cylinder 22 extending upwardly along the fastening cylinder 21. The cap module 30 has an installed state sealed within the fastening sleeve 20, and a quick-filling state after being rotary-opened; the upper cylinder 22 forms a quick-filling channel. A locking structure is provided between the cap module 30 and the upper cylinder 22, the locking structure being used to lock the cap module 30 in the installed state.

[0031] In this embodiment, switching to the rapid refueling state is achieved by rotating and opening the cap module 30. The upper cylinder forms a rapid refueling channel, allowing for quick refueling simply by rotating and opening the cap module 30, significantly reducing refueling time. With the cap module 30 installed, the seal between the cap module 30 and the fastening sleeve 20 effectively prevents air from entering the bottle. The locking structure between the cap module 30 and the upper cylinder 22 securely locks the cap module 30 in the non-rapid refueling state, preventing automatic opening due to accidental contact or tipping, and thus preventing oil leakage. The detachable design of the fastening sleeve 20 and the bottle body 10 facilitates cleaning the inside of the bottle body 10.

[0032] In this embodiment, the cap module 30 is hinged to the inside of the upper cylinder 22, and a hinge shaft 29 for rotating the cap module 30 is provided between the upper cylinder 22 and the cap module 30. After the locking structure is released, the cap module 30 is rotated around the hinge shaft 29 to open, allowing the bottle 10 to communicate with the outside world; rapid refueling is achieved through the rapid refueling channel enclosed by the upper cylinder 22. The cap module 30 is hinged to the upper cylinder 22. In the rapid refueling state, the cap module 30 is connected to the fastening sleeve 20 and can be temporarily placed on a table or container without disassembly. The hinge shaft 29 can be a separate component, or it can be set on the upper cylinder 22 or the cap module 30. The cap module 30 forms a fixed rotation axis through the hinge shaft 29 and the hinge hole 222 of the upper cylinder 22, ensuring that the trajectory of the cap module is stable when rotating around the axis; ensuring that it can be stably maintained in the rapid refueling state after opening, and can accurately return to the sealing position when closed, improving the reliability of operation.

[0033] In some embodiments of this application, the cover module 30 is provided with an outwardly protruding hinge protrusion 321, and the upper cylinder 22 is provided with a clearance notch 221 for avoiding the hinge protrusion 321. Two symmetrically arranged hinge holes 222 are provided at the clearance notch 221, and the hinge holes 222 are matched with the hinge shaft 29. The clearance notch 221 of the upper cylinder 22 provides movement space for the hinge protrusion 321 of the cover module, ensuring that the hinge protrusion will not collide or rub against the inner wall of the upper cylinder when the cover is rotated open.

[0034] In other embodiments of this application, the hinged connection between the cover module 30 and the upper cylinder 22 may also adopt other structural forms.

[0035] In some embodiments of this application, the cover module 30 has an inner cover 32 and an upper cover 32 assembled together. The upper cover 32 is located above the inner cover 31. An oil outlet 311 is provided on the inner cover 31, and an oil outlet cap 322 for pouring oil is provided on the upper cover. The oil bottle 100 is an oil bottle that pours oil by tilting.

[0036] In some other embodiments of this application, the oil bottle 100 may also be configured as an oil spray bottle, with an oil spray pipe provided on the inner cover 31.

[0037] In some embodiments of this application, the cover module 30 is provided with a lifting member 33, which can be pulled to open the cover module 30. A locking structure is provided between the lifting member 33 and the upper cylinder 22. The lifting member 33 has a closed state where the cover module 30 is locked, and an open state where the lock is released after rotation. After the locking structure is released, that is, when the lifting member 33 is in the open state, the cover module 30 can be rotated open by pulling the lifting member 33. The lifting member 33 is hinged to the upper cover 32. The lifting member 33 can lock and unlock the cover module 30 by rotation; and the lifting member 33 also has the function of pulling the cover module 30 to rotate open. In operation, simply rotate the lifting member 33 to release the lock, that is, switch to the open state, and then pull directly to rotate and open the cover module 30; the linkage design of the lifting member 33 greatly simplifies the operation steps and reduces the user's operational burden. The locking structure is located between the lifting member 33 and the upper cylinder 22. The closed state of the lifting member 33 directly corresponds to the locked state of the cover module 30; the open state of the lifting member 33 corresponds to the unlocking, and the cover module 30 can be lifted and rotated to open. Users can intuitively determine whether the cover module 30 is locked by observing the state of the lifting member 33.

[0038] In some embodiments of this application, the lifting member 33 is provided with a handle 331 for lifting operation, and the handle 331 is located above the hinge shaft 29. The handle 331 is located above the hinge shaft 29 and is consistent with the rotation trajectory direction of the cover module 30: when the user lifts his hand, his hand naturally exerts upward force, without the need to deliberately adjust his posture or apply lateral force, making the action smoother and more natural.

[0039] In some embodiments of this application, an inwardly extending sealing edge 23 is provided on the inner side of the fastening cylinder 20, and a first sealing ring 41 is provided between the sealing edge 23 and the upper opening of the bottle body 10. A second sealing ring 42 is provided between the cap module 30 and the sealing edge 23. A receiving groove 312 with a lower opening is provided on the cap module 30. The receiving groove 312 is used to receive the second sealing ring 42. The downward extension dimension of the outer groove wall 3121 of the receiving groove 312 is smaller than the downward extension dimension of the inner groove wall 3122 of the receiving groove 312. The longer extension of the inner groove wall 3122 of the receiving groove 312 can form a more stable inner support for the second sealing ring 42. When the cap module 30 is pressed down to seal, the second sealing ring 42 will preferentially be squeezed and deformed outward rather than collapsed inward. This deformation guidance allows the second sealing ring 42 to fit more tightly against the contact surface of the sealing edge 23. When the cover module 30 is rotated open via the hinge shaft 29, the design of the shorter outer wall of the receiving groove 312 can prevent it from colliding and interfering with the sealing edge 23 below or the inner side of the upper cylinder 22.

[0040] In some embodiments of this application, the fastening sleeve 20 further includes a lower cylinder 24 fitted onto the outside of the bottle body 10, with an observation port 241 on the lower cylinder 24 for observing the liquid level inside the bottle body 10. The lower cylinder 24 is a separate unit, with its upper end fitted onto the outside of the fastening sleeve 21, and a third sealing ring 43 is provided between the lower cylinder 24 and the fastening sleeve 21. A groove 11 matching the lower cylinder 24 is provided on the outside of the bottle body 10, and the lower cylinder 24 is located within the groove 11, with the height of the lower cylinder 24 being greater than 1 / 2 of the bottle body 10. The lower cylinder 24 covers the lower middle part of the bottle body 10 and serves as the main force-bearing part for the user to hold the oil bottle. Compared to directly holding the smooth bottle body 10, the lower cylinder 24 increases friction and improves the stability of the grip. The lower cylinder 24 is separately set from the fastening cylinder 21 and can be detachably assembled with the bottle body 10 through a groove. When the outside of the oil bottle is contaminated with oil, the lower cylinder 24 can be removed separately for cleaning, preventing oil from accumulating in the gaps and keeping the oil bottle clean. Example

[0041] See Figures 11-15 This is the second embodiment of a rotary-opening oil bottle proposed in this utility model. The main difference between this embodiment and the first embodiment is that the cap module 30 unlocks the locking structure by rotating.

[0042] A rotary-opening oil bottle 100 includes a bottle body 10, a fastening sleeve 20, and a cap module 30. The fastening sleeve 20 has a fastening cylinder 21 that is detachably and sealingly fastened to the bottle body 10, and an upper cylinder 22 extending upward along the fastening cylinder 21. The cap module 30 has an installed state that is sealed within the fastening sleeve 20, and a quick-filling state after being rotary-opened; the upper cylinder 22 forms a quick-filling channel. A locking structure is provided between the cap module 30 and the upper cylinder 22, the locking structure being used to lock the cap module 30 in the installed state.

[0043] In this embodiment, the cap module 30 is rotated and opened to switch to a rapid refueling state. The upper cylinder forms a rapid refueling channel, allowing for quick refueling simply by rotating and opening the cap module 30, significantly reducing refueling time. With the cap module 30 installed, the seal between the cap module 30 and the fastening sleeve 20 effectively prevents air from entering the bottle. The locking structure between the cap module 30 and the upper cylinder 22 securely locks the cap module 30 in the non-rapid refueling state, preventing accidental opening due to contact or tipping and thus preventing oil leakage. The detachable design of the fastening sleeve 20 and the bottle body 10 facilitates cleaning the inside of the bottle body 10.

[0044] In this embodiment, the locking structure is a rotary locking structure. The locking structure consists of multiple spaced first locking ribs 225 arranged circumferentially inside the upper cylinder 22, and multiple spaced second locking ribs 315 arranged circumferentially outside the cover module 30. The second locking ribs 315 are matched with the first locking ribs 225. The circumferential distance between two adjacent first locking ribs 225 is greater than the circumferential dimension of the second locking rib 315. This allows the second locking rib 315 to move downwards through the space between adjacent first locking ribs 225 after the cover module 30 is inserted into the upper cylinder 22. Then, through relative rotation between the cover module 30 and the fastening sleeve 20, the cover module 30 is locked inside the upper cylinder 22. The cover module 30 is in the installed state, with the second locking rib 315 located below the first locking ribs 225. The locking structure can be unlocked by rotating the cover module 30. The cover module 30 can then be opened upwards and removed. The cover module 30 is in a rapid refueling state and can be refueled through the rapid refueling channel enclosed by the upper cylinder 22. The cover module 30 is rotated before being opened. The first locking rib 225 and the second locking rib 315 engage through circumferential rotation to form a mechanical interlock; after the cover module 30 extends into the upper cylinder 22, the second locking rib 315 first moves down through the gap between the first locking ribs 225, and after rotation, it engages under the first locking rib 225, using the rigidity of the ribs to prevent the cover from moving upward, and the locking state is stable.

[0045] In some embodiments of this application, the cover module 30 has an inner cover 32 and an upper cover 32 assembled together. The upper cover 32 is located above the inner cover 31. An oil outlet 311 is provided on the inner cover 31, and an oil outlet cap 322 for pouring oil is provided on the upper cover. The oil bottle 100 is an oil bottle that pours oil by tilting.

[0046] In some embodiments of this application, an inwardly extending sealing edge 23 is provided on the inner side of the fastening cylinder 20, and a first sealing ring 41 is provided between the sealing edge 23 and the upper opening of the bottle body 10. A second sealing ring 42 is provided between the cap module 30 and the sealing edge 23. A receiving groove 312 with a lower opening is provided on the cap module 30. The receiving groove 312 is used to receive the second sealing ring 42. The downward extension dimension of the outer groove wall 3121 of the receiving groove 312 is smaller than the downward extension dimension of the inner groove wall 3122 of the receiving groove 312. The longer extension of the inner groove wall 3122 of the receiving groove 312 can form a more stable inner support for the second sealing ring 42. When the cap module 30 is pressed down to seal, the second sealing ring 42 will preferentially be squeezed and deformed outward rather than collapsed inward. This deformation guidance allows the second sealing ring 42 to fit more tightly against the contact surface of the sealing edge 23.

[0047] In some embodiments of this application, the fastening sleeve 20 further includes a lower cylinder 24 fitted over the outside of the bottle body 10, with an observation port 241 for observing the liquid level inside the bottle body 10. A groove matching the lower cylinder 24 is provided on the outside of the bottle body 10, and the lower cylinder 24 is located within the groove, with its height greater than half the height of the bottle body 10. The lower cylinder 24 covers the lower middle part of the bottle body 10, serving as the main force-bearing part for the user to hold the oil bottle. Compared to directly holding the smooth bottle body 10, the lower cylinder 24 increases friction and improves grip stability. The lower cylinder 24 is separately configured from the fastening sleeve 21 and can be detachably assembled with the bottle body 10 through the groove. When the outside of the oil bottle is contaminated with oil, the lower cylinder 24 can be removed separately for cleaning, preventing oil from accumulating in the gaps and keeping the oil bottle clean.

[0048] In some embodiments of this application, the fastening sleeve 20 is integrally formed, and the lower cylinder 24 extends downward along the fastening cylinder 21.

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.
