Is the thermos cup a vacuum cup?
Many people habitually combine the thermos cups with the vacuum cup. In fact, strictly speaking, thermos cups are not the same as vacuum cups. When many people mention thermos cups, they subconsciously think that they are stainless steel cups. In fact, there are not only stainless steel insulation cups, but also glass and ceramic insulation cups, but the material of the vacuum cup must be metal. Is the thermos cup a vacuum cup?
Many people can't distinguish what is an insulated water cup and what is a vacuum cup. In fact, only double-layer cups have room for vacuuming, and there are many single-layer cups on the market. The difference between a vacuum cup and a vacuum cup is the word vacuum. Ordinary insulated cups are not necessarily vacuum cups, but vacuum cups must be insulated cups. Ordinary stainless steel thermos cups generally hold about 4 hours, while vacuum cups can hold more than 12 hours. This is also the essential difference between a vacuum cup and a thermos cup. Therefore, when we buy the vacuum flask, we can give priority to the double-layer vacuum flask.
