The thermos cup is a container used to maintain the temperature of liquids. Its core function is to use the principle of blocking heat transfer to achieve the effect of heat preservation by blocking insulating heat convection through a double-layer vacuum structure. There are two layers of stainless steel inside the thermos cup with a vacuum layer in between. This vacuum layer isolates the heat from the outside, so that the temperature of the liquid inside can be maintained for a long time. The materials of the thermos cup include 304 stainless steel, 306 stainless steel, etc. These materials have good thermal insulation performance and durability.
The design of the thermos cup also includes components such as the inner tank, outer shell, lid and sealing ring, which together ensure the practicality and convenience of the thermos cup.
