Insulation cup selection skills

There are many varieties of stainless steel vacuum flasks on the market, and the prices vary greatly. For some consumers, they do not understand the principle and often spend a lot of money to buy satisfactory products. How can I buy a high-quality vacuum mug?

First look at the appearance of the cup. Take a look at whether the surface of the inner tank and the outer tank is uniformly polished, and whether there are bumps and scratches;

Second, see whether the mouth welding is smooth and consistent, which is related to whether it feels comfortable when drinking water together;

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

Four to see if the internal seal is tight. Whether the screw plug and cup body fit properly. Is it easy to screw in and out, and whether there is water leakage. Fill a full glass of water and turn it upside down for four or five minutes or give it a few vigorous shakes to check for leaks. Looking at the thermal insulation performance, this is the main technical indicator of the thermal mug. Generally, it is impossible to check according to the standard when purchasing, but it can be checked by hand after filling with hot water. The lower part of the cup body will heat up after two minutes of hot water, while the lower part of the insulated cup is always cool.

There are several methods as follows:

If the cup body is obviously warm, it means the product is The vacuum degree has been lost and a good thermal insulation effect cannot be achieved.

2. Sealing performance identification method: after adding water to the cup, tighten the bottle stopper and cup cover clockwise, and place the cup flat on the table, there should be no water leakage; the cup cover and the cup mouth should be flexibly screwed without gaps .
