Changes in living habitsAt first, people used to use thermos cups to drink hot water. With the economic development and accelerated pace of life, people started to use cold drinks. Especially in the hot summer season, adding ice cubes into boiled water has become a drinking habit of people. To facilitate drinking cold beverages, each special cold-insulated product is based on the original wide-mouth design to increase the use of small-caliber cold beverages.2. The special insulation for cooling is also suitable for insulation.With the changes in the drinking habits of the Chinese people, the replacement products are ready to come out, and all the major manufacturers have beaten the "Bao Leng" card. The nature of its products has not changed the performance of its thermal insulation products. It is only based on the original product design to increase the use of small-caliber cold drinks only. The cold insulation products can also achieve the insulation effect, because the insulation and cooling products have the same vacuum structure. The higher the vacuum technology, the better the product performance, the cold water is cold, and the hot water is thermal insulation. Because Han Kun products are sold globally, Chinese industry standards stipulate that hot drinks due to small-caliber products may cause burns and consumers must be informed of safety. Therefore, we recommend that consumers do not drink directly when hot drinks are too hot. Pay attention to the temperature of the drink in the cup while drinking.
