[0002] As people's daily needs increase, many people have developed the habit of drinking hot water, which greatly increases the demand for thermos cups. Most of the thermos cups on the market now use a vacuum layer between the inner and outer liner to slow down the conduction of heat, but the metal liner wall is a good conductor of heat. A large amount of heat in the cup will be conducted along the metal wall of the liner to the metal wall of the outer shell, and some thicker stainless steel liners are not only heavy, but also have obvious welding lines at the joints of the liner, which easily cause impurity accumulation. At present, the body of some thermos cup liners has been thinned to reduce the weight of the liner. A rubber sealing ring is added between the cup lid and the cup mouth to achieve water sealing, but the rubber sealing ring is deformed over a long period of use, resulting in a reduced heat sealing effect, and the problem of heat conduction loss in the neck section of the liner cup of the existing products still exists.
