Detailed Implementation

[0027] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0028] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures. Example 1

[0029] This embodiment mainly describes a cup lid and cup with a safety lock, as detailed below:

[0030] like Figures 1 to 7As shown, the cup lid and cup with a safety lock include a lower lid 1, an upper lid 2, and a flip-top 3 located between the lower lid 1 and the upper lid 2. The lower lid 1 is used to connect to the cup body 8 and has a drinking spout 11, allowing users to drink directly from it without frequently removing the lid like with traditional cups, greatly improving convenience. To prevent tea leaves or other infused substances from spilling out of the drinking spout 11 and affecting the user experience, a strainer integrated with the lower lid 1 is provided at the drinking spout 11. The flip-top 3 is hinged to one side of the lower lid 1, and the bottom surface of the flip-top 3 has a silicone plug corresponding to the drinking spout 11. When the flip-top 3 is closed on the lower lid 1, it seals the drinking spout 11, preventing liquid leakage. The upper cover 2 and the flip cover 3 are slidably connected. This sliding connection allows the upper cover 2 and the flip cover 3 to move relative to each other. The upper cover 2 is provided with a first latch 21, and the lower cover 1 is provided with a second latch 12 that cooperates with the first latch 21 and is fastened to the first latch 21. When the first latch 21 and the second latch 12 are engaged, the upper cover 2 and the flip cover 3 are locked together, ensuring that the flip cover 3 will not easily loosen when closed, thereby ensuring the sealing of the drinking spout 11 and preventing accidental liquid leakage. The upper cover 2 is slidably provided with a safety lock assembly 4 that locks the upper cover 2 onto the flip cover 3. When the first latch 21 and the second latch 12 are engaged, the sliding safety lock assembly 4 locks the upper cover 2 onto the flip cover 3. The upper cover 2 is locked and cannot move relative to the flip cover 3, which further enhances the stability of the cup lid and prevents the upper cover 2 and the flip cover 3 from accidentally separating due to external impact or misoperation, thereby avoiding the risk of liquid leakage. When the flip cover 3 needs to be opened, the safety lock component 4 must first be slid in the reverse direction to unlock the upper cover 2, and then the upper cover 2 must be slid to disengage the first latch 21 from the second latch 12 before the flip cover 3 can be opened. Compared to the prior art where the lid can be opened simply by pressing a button, this invention increases the difficulty of opening the lid, effectively preventing accidental opening due to misoperation, greatly improving safety, and avoiding potential burns caused by water spillage due to external impact or misoperation. While ensuring safety, this invention also considers ease of operation; users can open and lock the lid with a simple sliding motion.

[0031] like Figure 5 and Figure 7 As shown, the safety lock assembly 4 includes an actuating piece 41 and a connecting rod 42 fixed to the actuating piece 41. The connecting rod 42 has a protruding locking block 43, such as... Figure 6 , Figure 7As shown, the flip cover 3 has a locking position 321 that cooperates with the locking block 43. This cooperation structure between the locking block 43 and the locking position 321 allows the safety lock assembly 4 to effectively lock the upper cover 2 and prevent it from sliding. The side wall of the upper cover 2 has an arc-shaped groove 26, and the arc-shaped groove 26 has an arc-shaped slot 27 arranged along its length. The actuating piece 41 is slidably disposed in the arc-shaped groove 26, and the connecting rod 42 is inserted into the upper cover 2 through the arc-shaped slot 27 and connected to the upper cover 2. The actuating piece 41 can slide along the arc-shaped groove 26, driving the connecting rod 42 to slide along the arc-shaped slot 27. As the connecting rod 42 slides, it rotates around its connection point with the upper cover 2, causing the locking block 43 to engage or disengage from the locking position 321, thus locking or unlocking the upper cover 2. Specifically, when the locking block 43 is engaged in the locking position 321, the upper cover 2 is locked to the flip cover 3; when the locking block 43 is disengaged from the locking position 321, the upper cover 2 is in the unlocked state. This design makes the operation of the safety lock assembly 4 more flexible. The user can control the engagement state of the locking block 43 with the locking position 321 by actuating the piece 41, thereby locking and unlocking the upper cover 2. Simultaneously, the design of the arc-shaped groove 26 and the arc-shaped slot 27 makes the sliding of the actuating piece 41 and the connecting rod 42 smoother, improving operational comfort and reliability.

[0032] like Figure 6 As shown, the top surface of the flip cover 3 is provided with a guide groove 31 that extends from the drinking spout 11 along its hinge direction, such as... Figure 4 and Figure 5 As shown, the bottom of the upper cover 2 is provided with a guide rod 22 that extends into and slides along the guide groove 31. This cooperative structure of the guide groove 31 and the guide rod 22 can guide the sliding direction of the upper cover 2, ensuring that the upper cover 2 remains stable during sliding and avoiding jamming or displacement. The guide rod 22 has a connecting part 23 extending to the middle of the upper cover 2. The side of the connecting rod 42 away from the actuating piece 41 is provided with a fan-shaped hole 421 and a connecting hole 422 respectively fitted onto the guide rod 22 and the connecting part 23. When the actuating piece 41 slides and drives the connecting rod 42 to slide, the connecting rod 42 rotates around the connecting part 23 with the connecting part 23 as the rotation center, and the guide rod 22 slides relative to it along the fan-shaped hole 421. The design of the guide groove 31 and the guide rod 22 ensures that the upper cover 2 slides in a specified direction, which not only improves the stability of the upper cover 2 sliding, but also makes the sliding range of the upper cover 2 more precise, further enhancing the overall performance and reliability of the cup lid.

[0033] like Figure 7As shown, the flip cover 3 has a limiting groove 32 corresponding to the arc-shaped sliding groove 26. The connecting rod 42 passes through the limiting groove 32 and connects to the upper cover 2, and the connecting rod 42 can slide within the limiting groove 32. The limiting groove 32 near the groove wall of the locking block 43 forms the aforementioned locking position 321. When the locking block 43 is engaged in the locking position 321, the upper cover 2 is locked and cannot slide; when the locking block 43 is away from the locking position 321, the upper cover 2 can slide freely. This structure not only improves the locking effect of the safety lock assembly 4, but also makes the unlocking process smoother, allowing the user to unlock the upper cover 2 with a simple sliding operation. The setting of the limiting groove 32 and the locking position 321 further enhances the stability and reliability of the safety lock assembly 4, ensuring the safety of the cup lid during use. Alternatively, the locking position 321 can be replaced by a protruding limiting block (not shown in the figure) on the top surface of the flip cover 3, where the locking block 43 is engaged to prevent the upper cover 2 from sliding.

[0034] Specifically, the arc-shaped slide groove 26, the limiting groove 32, and the guide groove 31 are all located on the side of the flip cover 3 away from the hinge. This positional design makes the spatial layout of each component more reasonable and enables them to work together better. The arc-shaped slide groove 26 provides a track for the sliding of the actuating piece 41, the limiting groove 32 provides space for the sliding of the connecting rod 42, and the guide groove 31 provides guidance for the sliding of the upper cover 2. This relative positional design ensures that the actuating piece 41, the connecting rod 42, and the upper cover 2 do not interfere with each other when sliding, and makes the entire cup lid structure more compact, the operation smoother, and also improves the overall stability and reliability of the cup lid.

[0035] like Figure 7 As shown, the top of the flip cover 3 has a recessed mounting groove 33, and a guide groove 31 is located inside the mounting groove 33. A sliding channel 34 is formed between the two outer walls of the guide groove 31 and the two inner walls of the mounting groove 33. The two walls of the mounting groove 33 have slotted holes 331. Connecting plates 24 extending into the sliding channels 34 are provided on both sides of the bottom of the top cover 2. The two connecting plates 24 have sliders 25 extending into the slotted holes 331, and a guide rod 22 is located between the two connecting plates 24. When the top cover 2 slides relative to the flip cover, the sliders 25 slide along the slotted holes 331. This structural design makes the top cover 2 more stable during sliding. The sliding of the sliders 25 within the slotted holes 331 effectively limits the sliding direction of the top cover 2, preventing it from shifting or jamming during sliding. At the same time, the design of the mounting groove 33 and the sliding channel 34 provides sufficient space for each component, making the entire cup lid structure more compact and the operation smoother.

[0036] Specifically, the lower cover 1 has a guide wall 5 surrounding the edge of the drinking spout 11, and the height of the guide wall 5 gradually increases from the hinged side of the lower cover 1 towards the drinking spout 11. The end of the flip cover 3 away from its hinge is located inside the guide wall 5, and there are two second latches 12, which are respectively located on the two side walls of the guide wall 5. The guide wall 5 plays a guiding role, effectively preventing liquid from flowing out of the drinking spout 11 when water is dispensed. At the same time, the height variation design of the guide wall 5 can better guide the flow of liquid and improve the convenience of drinking. The second latches 12 are located on the two side walls of the guide wall 5, which can better cooperate with the first latch 21 to ensure that the flip cover 3 can fit tightly against the lower cover 1 in the closed state, further improving the sealing performance of the cup lid.

[0037] Specifically, the upper cover 2 has a clearance notch 6 near the hinge end of the flip cover 3, and the arc-shaped slide groove 26 is located on the side of the upper cover away from the clearance notch 6. The clearance notch 6 provides sufficient space for the hinge end of the flip cover 3, preventing interference between the upper cover 2 and the hinge end of the flip cover 3 during sliding. At the same time, the arc-shaped slide groove 26 is located on the opposite side of the clearance notch 6, making the sliding direction of the toggle piece 41 perpendicular to the sliding direction of the upper cover 2. This layout can better realize the function of the safety lock component 4 and improve the flexibility and reliability of operation.

[0038] like Figure 3 As shown, there is a sliding space 7 between the front end of the guide wall 5 and the front end of the upper cover 2, allowing the upper cover 2 to slide. The sliding space 7 is used to limit the sliding range of the upper cover 2. The design of the sliding space 7 can effectively prevent the upper cover 2 from sliding too far during the sliding process, thereby ensuring that the upper cover 2 always slides within a reasonable range. This design not only improves the operational stability of the cup lid, but also prevents the safety lock component 4 from failing due to excessive sliding of the upper cover 2, further enhancing the safety and reliability of the cup lid. Example 2

[0039] This embodiment mainly describes the cup, as follows:

[0040] like Figure 8 As shown, the cup includes a cup body 8 and a lid with the aforementioned safety lock. The cup body 8 is connected to the lower cover 1 of the lid. The cup body 8 can be a double-layered insulated cup or a plastic cup body. By combining the lid with the safety lock with the cup body 8, the inconvenience of frequently opening the lid of a traditional cup is solved, and the safety lock component 4 effectively prevents liquid leakage and scalding risks caused by accidental operation. The overall design of the cup ensures safety while also taking into account ease of use and comfort, making it suitable for daily life and office scenarios, and has broad market application prospects.
