What happens if you put Coke in a thermos?

Because cola is a carbonated beverage, it is easy to cause corrosion to stainless steel, and the inner liner of the thermos cup is made of stainless steel, so cola should not be placed in the thermos cup, otherwise drinking the cola in the thermos cup will reduce the life of the thermos cup in mild cases, and in severe cases It can also affect human health.

In addition to not putting cola in the thermos cup, milk, dairy products and other liquids containing acidic substances cannot be put into the thermos cup, because the acidic substance will have a chemical reaction on the stainless steel of the thermos cup, which will not only cause the drink to lose its original flavor. Taste, but also make the thermos cup rust due to oxidation.

Tips for buying stainless steel cups

1. Thermal insulation performance.

The thermal insulation performance of the vacuum bottle mainly refers to the inner container of the vacuum bottle. After filling with boiling water, tighten the cork or thermos cap clockwise. After about 2 to 3 minutes, touch the outer surface and bottom of the cup with your hands. If you notice a warm feeling, it means that the insulation is not good enough.

2. Sealing.

Pour in a glass of water, screw on the lid, and invert for a few minutes, or shake a few times. If there is no leakage, it proves that its sealing performance is good.

3. Health and environmental protection.

It is very important whether the plastic parts of the thermos are healthy and environmentally friendly. Can be identified by smell. If the thermos cup is made of food-grade plastic, it has little smell, bright surface, no burrs, long service life, and is not easy to age; if it is ordinary plastic, it will be inferior to food-grade plastic in all aspects.

4. Identification of stainless steel materials.

For stainless steel vacuum bottles, the quality of the material is very important. There are many specifications of stainless steel materials. 18/8 means that the stainless steel material contains 18% chromium and 8% nickel. Only materials that meet this standard are green products.
