The method of purchasing a thermos cup is very simple. It can be judged from four aspects: thermal insulation performance, tightness, plastic parts and materials. The detailed judgment methods are as follows. After you buy the thermos cup, will everyone use it? In fact, everyone will use the thermos cup in life, but not many people use the thermos cup healthily. Many people are used to using it as an ordinary cup every day, which is wrong. How to use the thermos cup correctly to help consumers’ own health? Next, let’s have a look!
Four ways to teach you to choose the right thermos cup
When we buy thermos cups, we naturally pay attention to the insulation effect and materials. How do we choose them? We can judge from the following four aspects:
1. Touch the bottom: see the insulation performance
The thermal insulation performance of the thermos cup mainly refers to the inner tank of the thermos cup. After filling the thermos cup with boiling water, tighten it. After about 2 ~ 3 minutes, touch the outer surface and lower part of the cup with your hand. If you find a warm feeling, it indicates that the thermal insulation performance is not good enough.
2. Shake it to see the tightness
Fill a cup of water, tighten the cup cover, turn it upside down for a few minutes, or throw it hard. If there is no leakage, it proves that its sealing performance is good.
3. Smell: check whether the accessories are healthy
The heat preservation cup 304 is easy to be made of plastic, has no smell and burr, and has a long service life.
4. Look at the specification: 18 / 8 (SUS304) is the “password” of the thermos cup
There are many specifications of stainless steel materials, among which 18 / 8 (SUS304) indicates that the composition of stainless steel materials contains 18% chromium and 8% nickel. Only materials meeting this standard are green products.
