[0002] At present, in many bottles, especially children's water cups, in order to facilitate drinking, a liquid outlet such as a suction nozzle and a pouring opening is additionally arranged on the bottle cap screwed on the bottle body, and a top cover is additionally arranged to lock the liquid outlet by a convenient opening structure such as a buckle. In many life scenes, a large number of bottles of different people are placed together. In this case, it is easy to mistakenly take the bottle and drink, which can easily lead to disease transmission and other problems.

[0003] Therefore, a safety bottle has recently appeared, which is provided with a fingerprint lock and other locking structures that need to be unlocked by specific unlocking elements, so that the top cover can only be opened by specific personnel, and the bottle cap also adopts a double-layer structure and is provided with a clutch structure cooperating with the top cover. Only when the top cover is opened, can the outer bottle cap be twisted to drive the inner bottle cap to rotate and unscrew the bottle cap from the bottle body. When the top cover is closed, the clutch structure separates the inner and outer bottle caps, so that the inner and outer bottle caps cannot be opened when the top cover is not unlocked, and other personnel cannot open the bottle to drink, effectively improving the safety of the bottle.

[0004] However, when filling water, the bottle cap generally needs to be opened to fill water through the large bottle opening of the bottle body, and the bottle cap can only be screwed onto the bottle body when the top cover is opened. Therefore, during the screwing process of the bottle cap, the top cover will hinder the screwing operation, which is not convenient to use, and during this process, the hands will inevitably touch the liquid outlet such as the suction nozzle, so that bacteria, dust and other contaminants on the hands are easily attached to the liquid outlet, which poses a certain health risk.

[0034] In the embodiment, according to general habits, the screwing direction is clockwise, and the unscrewing direction is counterclockwise. In other embodiments, the screwing direction and the unscrewing direction can also be interchanged, and are not limited thereto.

[0035] As a preferred embodiment of the utility model, it can also have the following additional technical features:

[0036] In the embodiment, the one-way linkage structure is a ratchet structure arranged between the outer cover 30 and the inner cover 20, which is simple and reliable, and facilitates processing, manufacturing and assembly. In other embodiments, other commonly used one-way structures can also be selected, and are not limited thereto.

[0037] In this embodiment, the ratchet structure includes a gear 51 disposed on the inner cover 20 and a resilient ratchet 52 disposed on the outer cover 30; the clutch structure includes a clutch member 61 movably disposed on the outer cover 30, the clutch member 61 having a engagement portion for engaging with the gear teeth 511 or tooth gaps 512 of the gear 51, and an elastic structure is provided between the clutch member 61 and the outer cover 30, the elastic structure being used to push the clutch member 61 in a direction that engages the engagement portion with the gear teeth 511 or tooth gaps 512 of the gear 51. Thus, utilizing the gear 51 in the one-way linkage structure as part of the clutch structure helps simplify the structure, making the safety bottle structure more compact and reducing product costs. In other embodiments, the clutch structure can also be separately provided, or a ratchet structure similar to the one-way clutch structure can be used, as long as it can ensure that the rotation of the outer cover 30 in the outward direction in the engaged state can drive the inner cover 20 to rotate in the same direction, and is not limited to this.

[0038] In this embodiment, the clutch 61 has a pressing portion 611 protruding from the outer cover 30. During closing, the top cover 40 presses against the pressing portion 611, causing the clutch 61 to move downwards. An inclined guide structure is provided between the outer cover 30 and the clutch 61. This guide structure allows the clutch 61 to move backwards away from the gear 51 during its downward movement. An elastic structure pushes the clutch 61 forward towards the gear 51. Thus, the opening and closing of the top cover 40 can automatically control the engagement and disengagement of the clutch structure without additional operation, making it more convenient and reliable. In other embodiments, the clutch structure can also be individually controlled for engagement and disengagement via a toggle switch or similar structure. Those skilled in the art can flexibly select and adjust as needed. In this embodiment, the outer cover 30 has a through hole 35 through which the pressing portion 611 passes.

[0039] In this embodiment, the engaging portion is a slot 612 that is adapted to the gear teeth 511 of the gear component 51 and allows the gear teeth 511 to be inserted. This structure is simple and easy to manufacture. In other embodiments, the engaging portion can also be a block inserted into the tooth gaps 512 of the gear component 51. Furthermore, in this embodiment, the front part of the clutch component 61 is adapted to the shape of the gear component 51. When the slot 612 engages with a gear tooth 511, the front part of the clutch component 61 simultaneously engages with the two tooth gaps 512 on both sides of the gear tooth 511, which can improve the firmness of the engagement, increase the difficulty of violent destruction, and make it safer and more reliable.

[0040] In this embodiment, the outer cover 30 is provided with two outer limiting plates 31 that abut against the left and right side walls of the clutch 61, and a middle limiting plate 32 that is slidably inserted into the slot 612. The middle limiting plate 32 and the two outer limiting plates 31 are each provided with a first inclined surface 33. The sides of the clutch 61 and the slot 612 are respectively provided with second inclined surfaces 613 that slidably abut against each of the first inclined surfaces 33. The guiding structure, including the first inclined surfaces 33 and the second inclined surfaces 613, can guide and limit the movement of the clutch 61, effectively preventing the clutch 61 from shifting or misaligning and causing malfunctions. It also improves structural strength, making the clutch structure less susceptible to damage and violent destruction. In this embodiment, an mounting component 34 is assembled inside the outer cover 30. The clutch 61 is located between the inner top surface of the outer cover 30 and the mounting component 34. The outer limiting plates 31 and the middle limiting plate 32 are also mounted on the mounting component 34, facilitating manufacturing and assembly.

[0041] In this embodiment, the elastic structure uses a spring 62, which is simple, reliable, and easy to manufacture and assemble. In other embodiments, the elastic structure can also use other suitable structures such as spring sheets, spring pads, or elastic arms. In this embodiment, the ratchet 52 uses a metal spring sheet with a "U"-shaped locking part 521 at its tail end. The outer cover 30 has a corresponding protrusion 38 inside. The ratchet 52 is assembled inside the outer cover 30 through the cooperation of its locking part 521 and the protrusion 38, resulting in a robust structure and facilitating the manufacturing and assembly of the outer cover 30. In other embodiments, the ratchet 52 can also use a spring arm or other suitable structure formed together with the outer cover 30, and is not limited to this.

[0042] In this embodiment, the inner cover 20 has a first protruding ring 21 on its outer side and a second protruding ring 22 on its bottom. The outer cover 30 has an anti-detachment protrusion 36 on its inner side that abuts against or is close to the bottom surface of the first protruding ring 21. The bottom inner side of the outer cover 30 has a stepped groove 37 that matches the second protruding ring 22. The second protruding ring 22 is accommodated in the stepped groove 37, and the stepped surface of the stepped groove 37 abuts against or is close to the top surface of the second protruding ring 22. This facilitates manufacturing and assembly, restricts the relative vertical movement of the inner cover 20 and the outer cover 30, and does not affect their relative rotation. Simultaneously, the outer cover 30 completely covers the inner cover 20, preventing direct rotation of the inner cover 20 from the outside, thus enhancing safety and reliability. In this embodiment, the lower wall of the anti-detachment protrusion 36 is sloped, which, combined with the elasticity of the inner cover 20 and the outer cover 30, allows for easy assembly of the two covers together. In other embodiments, the inner cover 20 and the outer cover 30 may also employ other commonly used structures such as ball bearings to achieve relative rotation.

[0043] In this embodiment, the locking device has a fingerprint recognition module 70, which can unlock the device by recognizing a fingerprint. The structure is simple, reliable, and easy to manufacture and operate. In other embodiments, the locking device can also adopt other commonly used structures, using different unlocking elements. For example, it can use chip information recognition for unlocking, a touchscreen combined with gesture unlocking, a voice recognition device for voice unlocking, or other commonly used structures such as a combination lock or key lock. It is not limited to these. In this embodiment, one end of the top cover 40 is pivotally connected to the outer cover 30 via a pivot shaft 41, while the other end is locked and unlocked by the locking structure of the locking device. This locking structure can adopt common structures such as a hook structure or a pin structure. These locking structures are widely used, and those skilled in the art can flexibly choose according to their needs; they will not be described in detail here.

[0044] In this embodiment, the liquid outlet is a suction nozzle 23, which is located on the inner cover 20 and extends through the outer cover 30 to the top of the outer cover 30, making it convenient for infants and young children to drink water. The suction nozzle 23 can also be used to pour liquid out of the bottle body 10. In other embodiments, the liquid outlet may adopt other suitable shapes and structures as needed, and is not limited to this.

[0045] This invention can be used as a water cup, kettle, wine bottle, baby bottle, juice bottle, shaker bottle, etc.

[0046] Without causing conflict, those skilled in the art can freely combine and use the above-mentioned additional technical features.

[0047] The above description is only a preferred embodiment of the present utility model. Any technical solution that achieves the purpose of the present utility model by essentially the same means shall fall within the protection scope of the present utility model.
