First look at the performance of the thermos cup.
The most important thing about a thermos cup is to keep it warm. If it can't keep warm, then it's not a thermos cup. A qualified thermos cup should keep the heat preservation effect for more than 6 hours. In the process of use, the holding time has a great relationship with the ambient temperature and the number of times of opening the cup. Stainless steel is the most used material, which has good insulation effect and is not expensive.
Second, safety is the most important.
The thermos cup is something to touch the mouth, so whether the materials and accessories are healthy, environmentally friendly and non-toxic is also the most important. The thermos cup should be made of food-grade plastic, which has small smell, smooth surface, no burr, long service life and is not easy to age.
Third, it is convenient to use and easy to clean.
When the baby drinks water, it depends on whether the cup is convenient to use. For example, it depends on whether the design of the cover is safe and not easy to burn children, and whether the straw can prevent splashing. Some thermos cups are not splash-proof, but the cover design can prevent water from spraying out, that is, the cover will not pop out immediately after being pressed, but pop out with a bang, which can prevent hot water from spraying out. When you don't drink, it is best to have a button on the thermos cup. Choose a cup with a diameter that is easy to clean and disassemble, and the more careful you clean it.
Four, the use of thermos cup matters needing attention
After buying a thermos cup, read the instructions, wash it with cold water and wash off the dust in the cup; After the first washing, wash it again with warm water and neutral detergent, and then rinse it with clear water; After washing twice, check whether there is a rubber ring on the lid, take it out and soak it in warm water for a while, but don't cook it. You don't need to soak the thermos cup itself, just soak the lid in warm water. When you use it, you should put a little boiling water in it and pour it out, and then add boiling water, so the effect is better.
