Description

Technical Field

[0001] This utility model belongs to the field of cup lid technology, and specifically relates to a cup lid. Background Technology

[0002] The lid is an important component of a thermos cup. It not only seals the cup but also helps the user drink the beverage inside.

[0003] To facilitate drinking from the beverage inside the cup, the lids of most insulated cups on the market consist of multiple parts. To maintain the cleanliness and hygiene of the lids, some lids can be disassembled for cleaning. For example, Chinese Utility Model Patent CN202221831602.8 discloses a lid that is easy to disassemble and clean. It includes a lid body connected to the cup body, a drinking spout on the lid body, and a sealing cap movably mounted on the lid body. The sealing cap has a plug for sealing the drinking spout. Connecting parts are provided on both sides of the sealing cap. Mounting grooves that mate with the connecting parts are provided on the lid body. Limiting protrusions are provided on the lid body, and limiting parts are provided on the sealing cap. The limiting protrusions abut against the limiting parts and prevent the connecting parts from detaching from the mounting grooves. The limiting parts can pass over the limiting protrusions under the action of external force and disengage the connecting parts from the mounting grooves.

[0004] In the above structure, the movement range of the sealing cap is restricted by the limiting protrusion. After frequent disassembly, the limiting protrusion is prone to wear, which affects the stable installation of the sealing cap.

6. A cup lid according to claim 1, 2, 3, or 5, characterized in that: The pressure cap (12) is provided with a sliding groove (126), and the snap-fit ​​part (6) is slidably disposed in the sliding groove (126). A first positioning protrusion (129) is provided on the side wall of the sliding groove (126), and a first positioning groove (64) and a movable groove (65) adapted to the first positioning protrusion (129) are provided on the side wall of the snap-fit ​​part (6). The first positioning protrusion (129) and the first positioning groove (64) cooperate to fix the snap-fit ​​part (6) and the pressure cap (12) relatively, and keep the snap-fit ​​part (6) and the base (11) in cooperation. Under the action of external force, the first positioning protrusion (129) can disengage from the first positioning groove (64) and cooperate with the movable groove (65), so that the snap-fit ​​part (6) can disengage from the base (11), and the base (11) and the pressure cap (12) can be disassembled relative to each other.

7. A cup lid according to claim 6, characterized in that: The pressure cap (12) is provided with a first limiting guide groove (128), and the snap-fit ​​part (6) is provided with a first guide hook (62) that is adapted to the first limiting guide groove (128). The first limiting guide groove (128) and the first guide hook (62) cooperate to keep the snap-fit ​​part (6) and the slide groove (126) in cooperation, and guide and limit the sliding of the snap-fit ​​part (6).

8. A cup lid according to claim 1, 2, 3, 5, or 7, characterized in that: The sealing element (2) is provided with a second positioning groove (28), and the base (11) or the cover (12) is provided with at least two second positioning parts (117) that are adapted to the second positioning groove (28).
