The concept of thermos bottle
The inventor of the thermos flask was British chemist and physicist James Duvall in 1892, hence it is also known as the Duvall flask. The concept of a thermos bottle is simple: the bottle has an inner wall and an outer wall; There is a vacuum between the two walls. Thermal conduction and convection cannot […]
The difference between a cooling cup and a thermos cup
The core insulation principle of the cooling cup and the insulation cup is completely the same, both using a vacuum layer for insulation to delay temperature changes, but the design details and marketing focus are different. 1. Essence and Principle Both use vacuum insulation technology to maintain the temperature of the contents by blocking […]
The difference between insulated cups and refrigerated cups
Cold cup and thermos may sound similar, but in fact, they each have their own unique ideas! Today, let’s talk about them and make it easy for you to choose cups. 1. Differences in material and structure Insulated cups are usually made of stainless steel or titanium and have a vacuum insulation layer inside, while […]
What is the standard insulation time for different quality insulated cups
1. High quality insulated cup These types of insulated cups usually use high-quality inner liner materials, such as 316 stainless steel, combined with advanced vacuum technology and good sealing design. After being filled with hot water at around 95 ℃, the water temperature can still remain above 50 ℃ -60 ℃ after 6-12 hours; After […]
The difference between an insulated coffee pot and a thermos
1. Definition of coffee pot and thermos Firstly, we need to understand the definitions of coffee pot and thermos. A coffee pot is a device used to brew coffee, which can be poured into a coffee cup for drinking. And a thermos is a device used for insulation, which can keep hot water or other […]
Is white thermos better or black
1. The core difference between white and black thermos cups (1) Temperature retention capability Black has strong heat absorption, but the insulation layer of the insulated cup (usually vacuum+copper plating) is the key to determining the insulation effect. Experiments have shown that white and black insulated cups of the same brand and model have a […]
