Selection Skills Of Stainless Steel Vacuum Flask

Nowadays, there are many varieties of stainless steel vacuum flasks on the market, and the prices are also different. When we consumers buy, they often don't know the difference, and spend a lot of money but fail to buy high-quality products. So how can we buy high-quality stainless steel vacuum flasks?

The purchase of stainless steel vacuum flask can be summarized into five points:

1. Look at the appearance. Check whether the stainless steel vacuum flask has bruises or scratches and whether the surface of the outer tank and the inner tank is uniformly polished.

2. Look at the mouth welding. Oral welding is about whether you feel comfortable when drinking water. Therefore, it is necessary to carefully observe whether the mouth welding is smooth and consistent.

3. Look at plastic parts. The quality of plastic parts is directly related to the life of a vacuum flask, and it also affects the sanitation of drinking water.

4. Look at the seal. Sealing refers to whether the internal seal is tight, whether the screw plug fits the cup properly, whether it is screwed in and out freely, and whether there is water leakage.

5. Look at the thermal insulation performance. When choosing stainless steel vacuum flasks, we can't check them one by one according to the standard, but we can rely on the touch. After filling the thermos cup with hot water, touch the lower part of the cup with your hand within two minutes. If it is insulated, it will always be cold, but the lower part that is not insulated will get hot.
