Description
Technical Field
[0001] This utility model belongs to the technical field of milk tea cup lids, and relates to a milk tea cup lid with a leak-proof function. Background Technology
[0002] As living standards continue to improve, milk tea and coffee have gradually become people's daily drinks. To make it easier for people to carry and drink milk tea, a lid is fitted onto the body of the milk tea cup. A drinking spout is opened on the lid for easy drinking, and an integrated cover is set on the lid to seal the drinking spout, making it convenient to carry.
[0003] However, when the cup contains a hot beverage, the heat causes the internal space to expand. The hot air then pushes against the sealing part, and the seal is not tight enough to properly close the opening, leading to leakage. Therefore, existing technology includes a structure with vent holes in the lid to release pressure within the cup. However, this type of lid still has some shortcomings. When the cup is tilted or shaken, the milk tea inside can easily flow out through the vent holes, causing spills and reducing the customer's drinking experience. Summary of the Invention
[0004] The purpose of this invention is to address the problems existing in the current technology by proposing a leak-proof milk tea cup lid. The technical problem to be solved by this invention is: how to prevent milk tea from leaking out of the vent.
[0005] The purpose of this utility model can be achieved through the following technical solution: a milk tea cup lid with a leak-proof function, including a lid body, a drinking spout on one side of the top of the lid body, an integrally connected lid piece on the side of the lid body away from the drinking spout, a sealing part corresponding to the structure of the drinking spout on the lid piece, a downwardly recessed groove on the top of the lid body, a retaining ring on the lid piece that can be inserted into the groove, a vent hole on one side of the bottom of the groove, an exhaust hole on the lid piece, the exhaust hole being located directly above the groove and away from the vent hole, and an upwardly protruding baffle at the bottom of the groove, the baffle being located between the vent hole and the exhaust hole.
[0006] In this design, the lid and the lid body are foldably connected. After flipping, the sealing part on the lid can be inserted into the drinking spout to seal it, keeping the lid airtight. A vent is provided on the lid body, allowing hot air from the cup to flow into the groove and then out through the exhaust vent at the top, reducing pressure inside the cup. By alternately placing the vent and exhaust vent at both ends of the groove, hot air and beverage inside the cup are prevented from directly spraying out through the exhaust vent, creating a gas flow channel inside the groove. A baffle is placed in the middle of the groove to act as a barrier. When the cup is tilted, the beverage flowing out of the vent will be blocked by the baffle, causing backflow and slowing the flow rate. This prevents the beverage from flowing to the side with the exhaust vent, thus preventing leakage.
[0007] In the aforementioned leak-proof milk tea cup lid, a toggle part is provided at the end of the lid away from the lid body, and an upwardly protruding ring edge is provided at the edge of the lid body. The toggle part can be engaged with the ring edge. Pushing the toggle part can easily flip up the lid, allowing the sealing part to be pulled out from the drinking spout for convenient drinking.
[0008] In the aforementioned leak-proof milk tea cup lid, the lid has a slot protruding towards the retaining ring. The middle section of the lid has a thin folded portion located between the sealing portion and the slot. One end of the lid with a lever-like part folds along the folded portion, allowing the lever-like part to be inserted securely into the slot. The slot and retaining ring can be inserted together into the groove, engaging the end with the lid. When the lever-like part is pushed to pull the sealing portion out of the drinking spout, the end with the sealing portion folds along the folded portion, and the lever-like part is then securely inserted into the slot, preventing the raised lid from touching the face.
[0009] In the aforementioned leak-proof milk tea cup lid, the inner walls on both sides of the slot are provided with first locking parts, and the actuating part is locked into the first locking parts. The slot is locked into the actuating part through the structure of the first locking parts, so that the actuating part is fixed inside the slot.
[0010] In the aforementioned leak-proof milk tea cup lid, the outer walls on both sides of the slot are provided with second engaging portions, and the inner walls on both sides of the groove are provided with corresponding limiting portions. The second engaging portions engage with the limiting portions. The second engaging portions cooperate with the limiting portions to make the slot and groove engage with each other.
[0011] In the aforementioned leak-proof milk tea cup lid, the lid sheet is provided with a leak-proof ring, which protrudes towards the side closest to the groove, and the vent is located inside the leak-proof ring. The vent, located inside the leak-proof ring, serves to prevent beverages from leaking out.
[0012] In the aforementioned leak-proof milk tea cup lid, the top of the lid body has two retaining edges, which are located on both sides of the drinking spout and the groove. The two sides of the lid can be flipped and embedded inside the retaining edges. A connecting part is provided on one end of the lid near the lid body, and the lid is connected to the lid body through the connecting part. The retaining edges clamp the lid on the inside, preventing contact with the lid and thus preventing the sealing part on the lid from being opened.
[0013] Compared with the prior art, the present invention has the following advantages:
[0014] 1. In this design, the vent and exhaust holes are staggered at both ends of the groove. This prevents hot air and beverage from being directly ejected from the exhaust hole, creating a gas flow channel inside the groove. A baffle is placed in the middle of the groove to act as a barrier. When the cup is tilted, the beverage flowing out of the vent will be blocked by the baffle, causing backflow, slowing down the flow rate, and preventing the beverage from flowing to the side with the exhaust hole. If only a small amount of beverage leaks out, it can even flow back into the cup.
[0015] 2. In this solution, the slot and the retaining ring can be inserted into the groove together, so that the end is engaged with the cover. When the push-operated part is pushed to pull the sealing part out of the drinking spout, the end with the sealing part is folded along the folding part, and the push-operated part is inserted into the slot to prevent the raised cover from touching the face.

[0021] Example
[0022] like Figure 1As shown, a leak-proof milk tea cup lid includes a lid body 1. A drinking spout 2 is located on one side of the top of the lid body 1. An integrally connected lid piece 3 is located on the side of the lid body 1 away from the drinking spout 2. The lid piece 3 has a sealing part 3a corresponding to the structure of the drinking spout 2. A downwardly recessed groove 7 is located on the top of the lid body 1. Limiting parts 7b are located on the inner walls of both sides of the groove 7. A vent hole 7a is located at the bottom of one side of the groove 7. A retaining ring 4 and a slot 5 are provided on the lid piece 3. The retaining ring 4 and the slot 5 are connected, and the retaining ring 4 and the slot 5 can be securely inserted into the groove 7. The lid piece 3 has a leak-proof design. The leak-proof ring 6a has an exhaust hole 6 inside, which is located directly above the groove 7 and away from the end of the vent hole 7a. The bottom of the groove 7 has an upwardly protruding baffle 8, which is located between the vent hole 7a and the exhaust hole 6. The end of the cover plate 3 away from the cover body 1 has a toggle part 3b. The edge of the cover body 1 has an upwardly protruding ring edge 1b. The toggle part 3b can be engaged with the ring edge 1b. The top of the cover body 1 has two baffles 1a, which are located on both sides of the drinking spout 2 and the groove 7. The two sides of the cover plate 3 can be flipped and embedded in the baffles 1a.
[0023] like Figure 2 Combination Figure 3 As shown, the cover plate 3 has a connecting part 3d at one end near the cover body 1. The cover plate 3 is connected to the cover body 1 through the connecting part 3d. The middle section of the cover plate 3 has a thin folding part 3c. The folding part 3c is located between the sealing part 3a and the slot 5. After the end of the cover plate 3 with the actuating part 3b is folded along the folding part 3c, the actuating part 3b can be inserted into the interior of the slot 5. The inner walls on both sides of the slot 5 have a first locking part 5a. The actuating part 3b is locked to the first locking part 5a. The outer walls on both sides of the slot 5 have a second locking part 5b. The second locking part 5b is locked to the limiting part 7b.
[0024] The working principle of this solution is as follows: Figure 1-3 As shown, the cover 3 is rotatably connected to the cover body 1. After being rotatably connected, the sealing part 3a on the cover 3 can be inserted into the drinking spout 2 to seal the drinking spout 2 and keep the cover body 1 in a sealed state. At the same time, the retaining ring 4 and slot 5 on the cover 3 are inserted into the groove 7. Pushing the actuating part 3b can easily flip the cover 3 up, so that the sealing part 3a can be pulled out from the drinking spout 2. Then, the end with the sealing part 3a is folded along the folding part 3c, and the actuating part 3b is inserted into the slot 5 to prevent the flipped-up cover 3 from touching the face and make drinking easier.
[0025] A vent 7a is provided on the lid 1, allowing hot air from the cup to flow into the groove 7 through the vent 7a and then out of the cup through the exhaust hole 6 at the top, reducing the pressure inside the cup. The vent 7a and exhaust hole 6 are staggered at both ends of the groove 7 to prevent hot air and beverage from spraying out directly from the exhaust hole 6, creating a gas flow channel inside the groove 7.
