The usage of takeaway coffee cups is as follows:

1. The packaged coffee is as shown in the picture. Drink cold drinks with a straw and drink hot drinks facing each other. Because coffee still tastes hot, straws are generally not provided.

2. In the picture, there is something like a small button on the lid of the coffee cup that can be pushed up. Push it up and insert it into the slot in front of it, and you can drink from the lid. The lid is to prevent coffee from spilling when walking, and the mouth is convenient for drinking while walking.

3. When drinking cold drinks, insert the straw into the position as shown in the picture, and you can drink it directly.

4. As shown in the picture below, the small red button has the following functions: First, it is for the ventilation of hot air and decompression. The second is to drink without opening the lid. If you don't open a hole and force the lid down, the lid will bulge. This is due to air pressure. When a cup of hot coffee is made, air and water vapor will rise upwards, so holes should be opened for ventilation to allow the air to release from the holes to relieve pressure. The lid will be easily closed if it does not receive pressure.
