[0023] The preferred embodiments of the present invention will now be described in detail 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.

[0024] 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.

[0025] This embodiment mainly describes the structure of the cup lid, as follows:

[0026] The double-layer direct drinking cup lid consists of an outer lid 1 and an inner lid 2 that fit together. Both the outer lid 1 and the inner lid 2 are made of PP material.

[0027] The outer cover 1 and inner cover 2 can also be made of metal, preferably stainless steel.

[0028] The outer cover 1 has a cavity 11 for accommodating the inner cover 2. The outer cover 1 also has a drinking port 12 and an air inlet 13 that communicate with the cavity 11. The drinking port 12 is located at the top edge of the outer cover 1 for the convenience of the user to drink water, and the air inlet 13 is located in the middle of the outer cover 1.

[0029] The inner cover 2 protrudes upward, forming an inner cavity 21 at its bottom. A drinking part 23 extends upward from the protrusion 22 and is adapted to the drinking spout 12. An air inlet pipe 24 also extends upward from the protrusion 22 and is adapted to the air inlet 13. Both the drinking part 23 and the air inlet pipe 24 are connected to the inner cavity 21. Water in the cup flows out from the drinking part 23 after passing through the inner cavity 21.

[0030] After the inner cover 2 is fitted inside the outer cover 1, the drinking part 23 is connected to the drinking port 12, and the air inlet pipe 24 is connected to the air inlet 13. The inner cover 2 seals the opening of the cavity 11, and the outer edge of the inner cover 2 is fixed to the inner wall of the cavity 11 by welding. In this way, the cup lid forms a double-layer structure, which has a better heat preservation effect.

[0031] A positioning cavity 14 is provided inside the cavity 11 at the drinking port 12. After the inner cover 2 is fitted inside the outer cover 1, the drinking part 23 is inserted into the positioning cavity 14. When the inner cover 2 is inserted into the outer cover 1, it can be better positioned to prevent the drinking part 23 from being misaligned with the drinking port 12.

[0032] Preferably, the shape of the drinking spout 12 is the same as the shape of the top opening of the drinking section 23, so that the water flows out more smoothly.

[0033] A sealing ring (not shown in the figure) is provided at the top of the air intake pipe 24. After the inner cover 2 is fitted inside the outer cover 1, the sealing ring is pressed tightly against the inner wall of the outer cover 1.

[0034] The outer cover 1 is also provided with a flip cover 3 for sealing the drinking spout 12. One end of the flip cover 3 is axially connected to the outer cover 1, and the other end of the flip cover 3 is engaged with the outer cover 1. Furthermore, the flip cover 3 is provided with a snap-fit ​​protrusion 31, and the outer wall of the outer cover 1 is provided with a slot 25 that engages with the snap-fit ​​protrusion 31.

[0035] The flip cover 3 is provided with a sealing protrusion 32. When the flip cover 3 is in the closed state, the sealing protrusion 32 blocks the air inlet 13.

[0036] The outer cover 1 has a groove 15. When the flip cover 3 is in the open state, the flip cover 3 can be stored in the groove 15 (e.g., Figure 7 (As shown), to prevent the lid from being opened while drinking water, which could affect the drinker.
