How does the quality of the thermos cup compare?

Recently, theeditor received a message from a reader friend who wanted to buy some thermos cups for friends to use. She saw many models on the Internet that I like, and the price is moderate. She wanted to buy them all back and compare them, and return the bad ones to keep the better ones. Want to ask how to compare to judge the quality of the water bottle?

The editor likes friends to ask questions, but what about this way of shopping comparison?It is a method, but it will also cause a waste of cost. The editor does not comment much, so I will return to this reader's message first.

How to compare two thermos cups or multiple thermos cups together?

First of all, let's take a look at the appearance. The well-made water cups are neat, the structure is rigorous, and they look neat. Those with poor workmanship will find that the shape of the water cup is somewhat awkward, with large gaps and rough workmanship. For example, there is almost no gap between the lid of a good water cup and the body of the cup after it is tightened. If it is not good, you will find that the gap between the lid and the cup body is small and wide, uneven. Good water cups have the same color and uniform coating, but bad water cups not only have inconsistent colors, but also have uneven spraying, deep and shallow.

The second is to feel it with your hands, and touch the water cup to see if there are any burrs (flaps) left during production. Whether each accessory is in good condition and whether it fits smoothly. When the cup lid is opened and closed, is there any problem such as poor sealing and difficult rotation back? Most of the water cups are cylindrical, and because the thermos cups need to go through multiple processes during production and processing.

When the quality control is not strict, there will be many out-of-round water cups flowing into the market. It is difficult to judge the out-of-roundness by looking at it, but you can clearly feel it by touching it with your hands. The out-of-round water cup does not affect the function of the water cup. However, compared with normal water cups, a certain proportion will destroy the structural integrity due to the out-of-round problem, reduce the service life of the water cup, and affect the quality of the water cup.

We can also judge contrast by smell.The smell is very strong, especially the pungent smell. No matter how good the workmanship of such water cups is, it cannot guarantee whether the materials are qualified, nor can it guarantee that the water cups will be polluted during storage and logistics transportation. You can also use some simple tests to judge whether the material is real or not, such as using a magnet to judge whether the stainless steel is 304 or not. You can also judge whether the thermal insulation performance is good by pouring hot water and feeling the surface temperature of the water cup.

The editor here to share with you a judgment method. Because the most talked about before is to feel the surface temperature of the water cup after pouring boiling water for 2 minutes (of course, this method is the most direct and accurate). If there is not enough hot water and you want to test multiple water cups, you can pour hot water into a third of the cups and pour it out after 20 seconds. The remaining water stains in the water cup do not need to be wiped dry. The higher the insulation effect of the water cup, the faster the internal water stains will evaporate by themselves.

These methods introduced by the editor can help friends filter out bad water glasses. But it cannot be said that the reserved water glasses must be of the best quality. As the saying goes, there is no best but better, and the water glass industry is the same.
