1, the apron of the cup cover is relatively simple to install. Just put the apron into the groove of the cup cover, and you can first lay the apron flat on the groove, and then press the apron with thin chopsticks.

2. Pay attention when buying an apron, and buy an apron that meets the specifications of the lid. Because the space of the cover groove is limited, the apron is usually put in, so the apron can't be put in the groove if it is too big, and it will fall off frequently if it is too small.

3. After installing the apron, you can pour some water into the cup, and then turn the cup upside down to see if there is any water leakage, so that you can check whether the sealing ring is installed correctly.

4. After installing the apron, cover and remove the cup cover several times to see if there is resistance. If there is no resistance, the apron and the cup are matched.
