Recently, I received a message from a reader friend who wanted to buy some thermos cups for friends to use. I saw many models that I liked online and the prices were moderate. I wanted to buy them all and compare them, and return the ones with poor quality to keep the quality. Even better, I would like to ask how to compare and judge the quality of water cups?
We love it when our friends ask questions, but what about this shopping comparison method? It is a method, but it will also cause a waste of cost. Not much comment here, let’s go back to this reader’s message first.
How do you compare two thermos cups or multiple thermos cups together?
First, let’s talk about the appearance. A well-made water cup is neat, well-structured and looks 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, if the lid of a good water cup is tightened, there will be almost no gap between it and the cup body. If it is not good, you will find that the gap between the lid and the cup body is small on one side and wide on the other, which is uneven. A good water cup will have the same color and even paint. A bad water cup will not only have inconsistent colors, but will even have uneven spraying with dark and light colors.
The second step is to get started, touch the water cup to see if there are any burrs (burrs) left during production, whether each accessory is intact and fit smoothly, and whether the cup lid is not tightly sealed when it is opened and closed, making it difficult to rotate back into place. And other issues. Most water cups are cylindrical. At the same time, because thermos cups need to go through multiple processes during production and processing, if quality control is not strict, there will be many out-of-round water cups flowing to the market. It is difficult to judge the out-of-round shape by looking at it, so just touch it. You can clearly feel it when you touch it. The out-of-round water cup does not completely affect the function of the water cup, but compared with the normal water cup, there is still a certain proportion of the out-of-round problem that damages the structural integrity, reduces the service life of the water cup, and affects the quality of the water cup.
We can also judge the comparison through the sense of smell. If the smell is very strong, especially the pungent smell, no matter how well-made such a water cup is, there is no guarantee whether the material is qualified, nor can it guarantee that the water cup will be damaged during storage and logistics transportation. pollute. You can also use some simple tests to determine whether the material is genuine, such as using a magnet to determine whether stainless steel is 304, etc.
You can also judge whether the heat preservation performance is good by pouring hot water and feeling the surface temperature of the water cup. Here I would like to share with you a judgment method, because what has been talked about most 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 one-third of the water cup, and pour it out after 20 seconds. There is no need to wipe away the remaining water traces inside. The higher the insulation effect of the water cup, the faster the water traces inside will evaporate on their own. #Thermos cup
The methods we introduced can help friends filter out bad water cups, but it cannot be said that the retained water cups must be of the best quality. As the saying goes, there is no best, only better, and the same is true for the water cup industry.
