Precautions for thermos cup
Insulation cups are generally used exclusively for veterans in everyone's minds, but don't young people need thermos cups? As the weather turns cold, the mineral water in the supermarket is not conducive to environmental protection, nor can it meet your demand for hot water.
Therefore, it is very necessary to have a vacuum flask, and the vacuum flask is not only for veteran officials. The vacuum flask is a symbol of fashion, environmental protection and health in Europe, America and other countries.
Next, let me talk about the precautions of the vacuum flask!
1.Tightness
Fill the cup with water, tighten the lid, and turn it upside down. The cup does not leak water, which proves that the cup is tightly sealed.
2.Insulation performance
Pour boiling water into the thermos cup, tighten the lid, leave it for a few minutes, and then touch the body of the cup with your hands. If the body of the cup is hot, especially the bottom of the cup, it means that the insulation performance is not good.
3.Drinks
Unless special materials are used for protection, the thermos cup can only hold water in principle.
It is not suitable to keep acidic beverages, such as fruit juice, lemonade, etc., or to make tea or milk.
4.Cleaning
When cleaning the thermos cup, do not use steel wire to scrub the surface of the inner tank. For some difficult to remove stains, you can rinse with neutral detergent or professional cleaning agent.
