How to use Starbucks takeaway coffee?

The usage of takeaway coffee cups is as follows:

1, packaged coffee is shown in the picture, cold drinks are drunk through straws, and hot drinks are the opposite of drinks. Because coffee is still hot and delicious, it is generally not equipped with straws.

There is something like a small button on the coffee cup cover in the picture. Push it up, insert it into the slot in front of him, and you can drink it against the lid. The lid is designed to prevent coffee from spilling when walking, and the mouth is convenient to drink while walking.

3. When drinking a cold drink, just insert the straw into the position shown in the figure, and you can drink it directly.

4. As shown below, the small red button has the following functions: First, it is used to ventilate hot air and relieve pressure. The second is not to open the lid of the cup to drink. If you don't make a hole, press the lid down hard, and the lid will bulge, which is the reason of air pressure. A cup of hot coffee, gas and steam are rising upwards, so it needs to be ventilated by opening a hole, so that the gas can be released from the hole to discharge the pressure, and the lid can be easily closed without pressure.
