Can I put soda in a thermos? Why?

The thermos cup can keep warm and keep ice. It is very comfortable to put ice water in summer. As for whether you can put soda, it mainly depends on the inner tank of the thermos cup, which is generally not allowed. The reason is very simple, that is, there is a large amount of carbon dioxide in the soda water, and a large amount of gas will be generated when shaken, and it will be difficult to open the thermos bottle after the internal pressure rises. And frequent release of soda may reduce the service life of the thermos cup.

We all know that soda contains the most carbon dioxide. The reason why so many people like it is that drinking soda can make you burp, and burp will release a certain amount of heat. The thermos cup can also keep ice. Putting ice soda into the thermos cup can make summer very comfortable. Logically speaking, this method is feasible, but in fact this method will bring a lot of trouble to oneself. The liner of the thermos cup is mostly made of high-manganese and low-nickel steel. When this material encounters acid, it will decompose heavy metals. Doing so for a long time will harm the body. Moreover, drinks with high sweetness will breed certain bacteria, and the thermos cup must be cleaned frequently

2. Affect drinking water
The biggest feature of soda is “steam”. For example, the common Sprite and Coke will have a lot of gas in them when they are shaken. When we open the bottle, it pops out all at once. This is not so serious for the thermos cup. However, after the gas appears, the pressure inside the thermos cup will increase. At this time, it becomes difficult to open the thermos cup. The pressure inside and outside is different, so it takes more force to twist the lid. It may also be the case with hot water, after all, internal and external pressure is an important factor of influence. It would be embarrassing if I couldn’t unscrew it by myself.

3. Service life
The thermos cup has a service life. After a certain period of time, the effect of the thermos cup will become worse and worse. Using a thermos cup to hold ice water will affect its service life. So use it to hold soda, even more so. At that time, the thermos cup will become useless, and it will be almost the same as an ordinary cup.
