1. The flip cover of the cup lid can be opened in a sliding unlocking manner. When the button is at the locking position, the flip cover is kept closed, and when the button is translated to the unlocking position, the flip cover can be opened, so the operation is convenient. When closed, the flip cover can be locked by the hook and the catch, thereby achieving a good locking effect and avoiding water leakage.

2. In the closing process of the flip cover, the hook slides along a horizontal direction (i.e., along an arrangement direction of the translation groove) and is locked by the catch, and the hook and the catch can only be unlocked through the translation of the button. In this way, the flip cover can be well limited from flipping up.

3. When the flip cover is closed, the drinking opening is blocked by the sealing block. In this case, when the flip cover is closed, the drinking opening can be sealed by the sealing block, thereby improving the sealing performance of the drinking opening when the flip cover is closed and avoiding water leakage.

4. An elastic force for opening is applied to the flip cover through the torsion spring. When the flip cover is closed, the torsion spring cannot drive the flip cover to open because the hook is engaged with the catch, and once the hook is separated from the catch, the torsion spring can automatically open the flip cover.

5. Since the hook and the catch are both located in the avoidance groove, the hook and the catch can pass through the flip cover and can be connected to each other or separated from each other. Moreover, the arrangement of the avoidance groove can also prevent the hook from interfering with the flip cover during the translation of the button.

DETAILED DESCRIPTION OF THE INVENTION

The following is specific embodiments of this disclosure and further describes the technical solution of this disclosure with reference to the drawings, but this disclosure is not limited to these embodiments.

As shown inFIGS.1to4, a cup lid assembly includes a cup lid body100, a flip cover200and a button400, wherein the cup lid body100can be detachably connected with a cup body, and a catch110is arranged on an upper end surface of the cup lid body100; the flip cover200is connected to the cup lid body100in a flipable manner, so that the cup lid can be opened or closed. Specifically, the cup lid can be flipped to a closed position or an open position.

The button400is configured for unlocking. The button400is connected with the flip cover200and capable of translating on the flip cover200, and the button400can move to a locking position or an unlocking position. The button400is provided with a hook410, and the hook410and the catch110can be locked together.

It should be noted that as mentioned above, the button400is connected with the flip cover200and can translate on the flip cover200, which means that the button400can only translate relative to the flip cover200, so the button400is equivalent to a part of the flip cover200. When the button400and the cup lid body100are locked together, it is equivalent to that the flip cover200and the cup lid body100are locked together, so that the flip cover200cannot be rotated.

The button400is translationally arranged on an upper end surface of the flip cover200, the flip cover200is provided with an avoidance groove220, the avoidance groove220is structured as a through hole, and the hook410and the catch110are both located in the avoidance groove220, so that the hook410and the catch110can pass through the flip cap200and can be connected to each other or separated from each other. Moreover, the arrangement of the avoidance groove220can also prevent the hook410from interfering with the flip cover200during the translation of the button400.

The flip cover200is provided with a translation groove230, and the button400is arranged in the translation groove230and can move along the translation groove230. Since the button400can only translate along the translation groove230, during the closing process of the flip cover200, the hook410slides along a horizontal direction (i.e., along an arrangement direction of the translation groove230) and is locked in the catch110, and the hook410and the catch110can only be unlocked through the translation of the button400. In this way, the flip cover200can be well limited from flipping up. Even though the flip cover200is subjected to a force to make it flip up, the button400cannot be translated, which ensures the reliable locking of the button400very well.

In an actual structure, limiting grooves270are formed in two sides of the translation groove230, limiting blocks430are arranged on two sides of the button400, and the limiting blocks430are arranged in the limiting grooves270, so that the sliding stroke of the button400can be limited, and the button400and the flip cover200can be fixed together.

As shown inFIGS.1and2, the flip cover200is provided with an elastic member300. The elastic member300can be configured as a spring or elastic silica gel part or other elastic components. The elastic member300is connected with the button400. A cavity is formed between the flip cover200and the button400. The elastic member300can be flatly placed in the cavity, and two ends of the elastic member300respectively push against and are in connection with the button400and the flip cover200.

Specifically, the elastic element300keeps the button400at the locking position, and when the button400is at the locking position, the hook410is connected with the catch110and limits the flip cover200from being opened (in this case, the flip cover200is at the closed position). When the button400is moved to the unlocking position, the hook410is separated from the catch110.

Therefore, the elastic member300has at least two functions: 1. when the flip cover200is closed, the elastic member300pushes the hook410to be locked with the catch110, thus ensuring the locking reliability of the flip cover200; 2. when the button400moves toward the unlocking position, the elastic member300is compressed and can drive the button400to return.

Therefore, the flip cover200of the cup lid can be opened in a sliding unlocking manner. When the button400is at the locking position, the flip cover200is kept closed, and when the button400is translated to the unlocking position, the flip cover200can be opened, so the operation is convenient. When closed, the flip cover200is locked by the hook410and the catch110, thereby achieving a good locking effect and avoiding water leakage.

As shown inFIGS.1,2and4, on the basis of the above embodiment, the cup lid body100is further provided with a drinking opening130, and when the flip cover200is closed, the flip cover200covers the drinking opening130and the hook410is connected with the catch110. Preferably, the flip cover is provided with a sealing block, and when the flip cover200is closed, the drinking opening130is blocked by the sealing block210. In this way, it can be ensured that the sealing block210seals the drinking opening130when the flip cover200is closed, thereby improving the sealing performance of the drinking opening130and avoiding water leakage.

The flip cover200is provided with a rotating shaft250and hinged with the cup lid body100through the rotating shaft250. A torsion spring260is fitted over the rotating shaft250, one end of the torsion spring260is connected with the cup lid body100, and the other end of the torsion spring260is connected with the flip cover200. When the hook410is separated from the catch110, the torsion spring260drives the flip cover200to open.

Preferably, an elastic force for opening is applied to the flip cover200through the torsion spring260. When the flip cover200is closed, the torsion spring260cannot drive the flip cover200to open because the hook410is engaged with the catch110, and once the hook410is separated from the catch110, the torsion spring260can automatically open the flip cover200.

As shown inFIGS.1and2, the hook410is provided with a first driving surface420, and the catch110is provided with a second driving surface120. When the flip cover200is flipped toward the cup lid body100, the first driving surface is matched with the second driving surface and the button400is then driven to move, so that the hook410is connected with the catch110.

It should be noted that, because the elastic member300can push the button400to the locking position, when the flip cover200is to be closed again, there is a problem that the hook410interferes with the catch110, resulting in that the flip cover200cannot be closed. To ensure that the hook410is automatically engaged with the catch110during the closing process of the flip cover200, the first driving surface420and the second driving surface120are specially provided.

Preferably, the first driving surface420and the second driving surface120can be configured as an inclined surface or a cambered surface. In the movement process of the flip cover200flipped toward the cup lid body100, firstly, the first driving surface420and the second driving surface120push against and are connected with each other, and then the button400is pushed by the hook410to move toward the unlocking position for a short distance. In this way, the flip cover200can be completely closed on the cup lid body100, and in this case, the elastic member300pushes the button400to return to the locking position, and the hook410is connected to the catch110.
