Carbonated beverages also contain acidic substances, which will chemically react with the stainless steel material in the inner layer of the thermos cup, producing harmful substances and causing harm to human health.

Due to the good insulation effect of the thermos cup, the carbon dioxide gas in the carbonated beverage will dissolve in water, causing the beverage to become more acidic and taste worse.

Therefore, it is not recommended to fill the thermos with carbonated drinks. If you need to carry drinks, it is recommended to choose a special beverage bottle or kettle, and pay attention to maintain the balance of pressure in the bottle to avoid danger.

Therefore, to ensure the safety and taste of milk drinks, it is recommended to put milk drinks in glass bottles or plastic bottles and drink them in a short time.

3.Do not contain tea in the stainless steel thermos cup

Some components contained in tea are easy to decompose at high temperatures and react with the stainless steel material of the thermos cup, producing harmful substances and causing harm to health.The thermal insulation of the stainless steel thermos cup will also cause the excessive release of tannic acid, theophylline and other ingredients in the tea, reducing the taste of the tea, thus affecting the quality of the tea.And tea stored in the thermos cup for too long is easy to make it damp or mildew, affecting the taste and health of the tea.
