Introduce the source of the thermos cup

A thermos cup, simply put, is a cup that can keep warm. Generally, it is a water container made of ceramic or stainless steel with a vacuum layer. It has a cover on the top and is tightly sealed. The vacuum insulation layer can delay the heat dissipation of the water and other liquids contained inside to achieve the purpose of heat preservation.
The invention of the thermos can be traced back to the 1880s, when Scottish scientist Sir James Duval invented the first vacuum thermos. He uses the vacuum in the double-walled glass bottle to stop heat transfer so the drink stays warm.
With the development of technology, the thermal insulation effect of the thermos cup is getting better and better. There are many types of thermos cups on the market, such as stainless steel, pottery, plastic and other materials, all of which have different characteristics and uses.
In the future, as consumers have higher and higher requirements for quality of life and healthy life, the function and quality of thermos cups will continue to improve. For example, develop more efficient insulation materials, increase intelligent functions, improve product durability and environmental protection, etc. In addition, with the popularization of green environmental awareness, reusable environmentally friendly thermos cups will also become one of the future development trends.
