[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0032] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0033] Please see Figure 1-3 This utility model provides a technical solution: a leak-proof beverage cup lid, comprising:

[0034] The cup lid body 1 has a flip-top slot 11 on it;

[0035] A boss 2 is provided on the top side of the cup lid body 1, and a latch 20 is provided on it. A drinking spout 201 is provided on the inner side of the latch 20.

[0036] The flip cover 3 includes a positioning block 31 and a positioning plate with a drinking spout 34. The positioning block 31 is embedded and snapped into the flip cover slot 11. The positioning plate has a Z-shaped structure and is flipped and disposed on one side of the positioning block 31 and tightly attached to the top surface of the cup lid body 1 and the surface of the boss 2. The drinking spout 34 is snapped into the slot 20.

[0037] Among them, the flip cover 3 is integrally formed by vacuum forming process, and the cup lid body 1 and the boss 2 are integrally formed by vacuum forming process.

[0038] Both the flip-cover slot 11 and the positioning block 31 are U-shaped structures. A retaining ring 311 is provided on the inner end face of the positioning block 31, and the retaining ring 311 engages within the flip-cover slot 11. A perforation 312 is provided on the inner side of the retaining ring 311 on the positioning block 31, and a guide block 313 is provided on the side of the perforation 312. The irregularly shaped structure of the flip-cover slot 11 and the positioning block 31 improves the engagement strength. The retaining ring 311 allows for elastic pre-tightening when engaging with the flip-cover slot 11. The perforation 312 allows communication between the closed flip-cover slot 11 and the outside after the positioning block 31 is assembled, preventing the positioning block 31 from being ejected due to relatively high internal pressure, thereby improving assembly strength.

[0039] The positioning plate includes a first bonding plate 32, a second bonding plate 33, a third bonding plate 35, and a fourth bonding plate 36. The first bonding plate 32 is bonded to the top surface of the cup lid body 1. The second bonding plate 33 is bonded to the upper end surface 21 of the boss 2, on which the drinking spout block 34 is provided. The third bonding plate 35 and the fourth bonding plate 36 are bonded to the inner side surface 22 and the outer side surface 23 of the boss 2, respectively. The bonding and positioning of multiple surfaces makes the positioning plate and the cup lid fit tightly, thereby making the positioning of the drinking spout block 34 and the latch 20 more stable.

[0040] The fourth bonding plate 36 has a U-shaped structure to be used in conjunction with the curved outer surface 23. The local deformation formed by pressing it can achieve a tighter structural fit.

[0041] The positioning plate and positioning block 31 are connected by an arc-shaped bending plate 37. The arc-shaped bending plate 37 is embedded in the curved groove 12 of the cup lid body 1 to limit the folding part of the flip cover 3 and prevent it from shifting or shaking.

[0042] A recess 13 is provided on the side of the cup lid body 1 opposite to the protrusion 2. A protrusion 14 is provided inside the recess 13, and the positioning groove on the end face of the drinking spout 34 engages with the protrusion 14. A pre-tightening block 15 is provided on the side of the recess 13, and the pre-tightening block 15 abuts against the side edge of the positioning plate. This design allows the positioning plate to be embedded and positioned when the lid 3 is folded and the drinking spout 201 is opened, through the recess 13, the protrusion 14, and the pre-tightening block 15, improving ease of use.

[0043] The working principle of a leak-proof beverage cup lid in this embodiment includes: during the flip-top assembly, the retaining ring 311 is pressed into the flip-top retaining groove 11 to position the positioning block 31. The arc-shaped bending plate 37 is embedded and positioned in the curved groove 12, and it can then be used. When the drinking spout 201 is opened, the positioning plate is folded towards the recess 13, the drinking spout retaining block 34 is pressed into the recess 13, and its end face is sleeved on the protrusion 14. The pre-tightening block 15 abuts against the side of the positioning plate to position the flip-top 3 and prevent it from shaking. At this time, the drinking spout 201 can be used. When the drinking spout 201 needs to be sealed, the positioning plate is pried out from the recess 13 and sleeved on the protrusion 2, so that the drinking spout retaining block 34 is engaged on the retaining slot 20, and the positioning plate is pinched to make it fit the surface of the protrusion 2 and the top surface of the cup lid body 1.

[0044] In summary, due to the adoption of the above technical solution, the leak-proof beverage cup lid of this embodiment has the following advantages compared with the prior art:

[0045] The flip-top of this cup lid is integrally molded using a vacuum forming process. The main body of the cup lid and the protrusion are integrally molded using a vacuum forming process. One end of the flip-top is positioned on the main body of the cup lid by a positioning block. The Z-shaped positioning plate design ensures that it fits tightly against the protrusion and the main body of the cup lid, thereby preventing the drinking spout from loosening or falling out, improving the leak-proof effect and sealing strength. The arc-shaped bending plate, together with the curved groove, can limit the flip-top at the flip-top folding point, thereby reducing the shaking at both ends. When the flip-top is folded and the drinking spout is opened, the positioning plate can be embedded and positioned by the notch, protrusion, and pre-tightening block, improving the ease of use.

[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
