Is the Vacuum Flask a vacuum cup? Many people like to mix the vacuum flask with the vacuum cup. In fact, strictly speaking, the vacuum flask is not the same as the vacuum cup. Just like a vacuum flask, most people will subconsciously think that it is a stainless steel cup. There will only be stainless steel cups, there will also be glass and ceramic cups, and the material of the cup must be metal!
The difference between the vacuum cup and the vacuum cup lies in the word "vacuum". The ordinary vacuum cup is not necessarily a vacuum cup, but the vacuum cup must be a vacuum cup. The ordinary stainless steel vacuum flask generally has a heat preservation time of about 4 hours. The Stainless Steel Vacuum Cup can be kept for more than 12 hours, which is the difference between the vacuum cup and the vacuum cup. Therefore, if you want to say which vacuum cup and vacuum cup are better, then the vacuum cup is better than the vacuum cup!
Not only the effect of heat preservation, the time of keeping the cup cold and the time of keeping the vacuum cup cold are also inconsistent. In general, the cup with longer heat preservation time will have a better cold preservation effect, and the cup with the best insulation effect is afraid. There is only a Portable Stainless Steel Vacuum Cup , so we must remember this when buying a vacuum flask, prefer a double vacuum cup!
