  It is actually very simple to buy a thermos pot:

1. Check whether the inner liner and outer surface are polished evenly, and whether there are bumps and scratches;
2. Check whether the mouth of the kettle is smooth and consistent, which is related to whether the feeling is comfortable when drinking water;
three. Looking at the plastic parts, the qualified ones should only have a slight smell (the new pot will have some plastic smell). If the smell is too heavy, it is an unqualified product. The poor quality plastic parts will not only affect the service life, it will also affect the sanitation of drinking water;
4. Check whether the internal sealing ring is tight. Whether the plug and body fit tightly. Screw in and out freely, and whether it leaks. Fill a pot of hot water upside down for about 5 minutes or shake it hard to verify whether it leaks;
5. Look at the insulation performance, this is the main technical index of stainless steel insulation pot. It can be felt by hand after being filled with boiled water. After the heat preservation not available pot is filled with hot water for two minutes, the lower part of the cup body will heat up, while the lower part of the insulated pot is always cool (note: it is normal that there is a slight temperature near the kettle mouth, because pot lid places cannot be vacuum).

Precautions for use: avoid hitting the body, do not fall to the ground, damage the body or plastic accessories, so as not to damage the vacuum layer of the pot to make the insulation fail or cause water leakage. Tighten the inner cover or outer cover with moderate force and do not overforce, so as not to screw slippery.
