When driving, just press the red button in the middle, and water will automatically flow out without splashing on the car; Some have a tea partition design in the middle of the insulated cup, which can quickly filter tea leaves and water, making it very suitable for small white-collar workers in the office; There is also a double cup design, with a hidden compartment for storing tea, sugar, and coffee on the bottom box cover. The vacuum inner container made of stainless steel double-layer can not only hold hot water but also ice water. Some cups also have a stewing function, and the least functional thermos has at least 2 or more functions. The most functional thermos has 4-5 functions, making it very convenient for travel or home use.
