How can I buy high-quality vacuum insulation cups?

First, look at the appearance of the cup. Check whether the surface polishing of the inner and outer bladder is uniform, and whether there are bruises and scratches;

Second, check whether the mouth welding is smooth and consistent, which is related to whether it is comfortable to drink together;

Third, the quality of plastic parts is poor. It will not only affect the service life, but also affect the sanitation of drinking water;

Fourth, check whether the internal seal is tight. Check whether the screw plug and cup body fit properly. Whether the screw in and screw out are free and whether there is water leakage. Fill a glass of water and invert it for four or five minutes or shake it vigorously to verify whether there is water leakage. Then look at the thermal insulation performance, which is the main technical index of the thermal insulation cup. It is impossible to check according to the standard when purchasing, but it can be checked by hand after being filled with hot water. The lower part of the cup will heat up after two minutes of hot water is filled in the cup without heat preservation, while the lower part of the cup with heat preservation is always cool.
