Thermos Flask

Thermos Flask is generally a water-filled container made of ceramic or stainless steel plus a vacuum layer. The top is covered and the seal is tight. The vacuum insulation layer can delay the heat dissipation of liquid such as water inside to achieve the purpose of heat preservation.
The cup is developed from the thermos bottle. The principle of heat preservation is the same as that of the thermos bottle. It is just that people make the bottle into a cup for convenience.
Functions
The appearance is smooth and odorless. After injecting boiling water, the cup with no heat can be called a good cup.
The inner and outer parts are made of stainless steel and refined with advanced vacuum technology. The shape is elegant, the liner is seamless, the sealing performance is good, and the insulation performance is good. Ice cubes can be placed, or hot drinks can be placed. At the same time, functional innovation and detailed design also make the new insulation cup more connotation and practicality.
Shopping tips
There are many varieties of Thermos Flask sold on the market, and the price difference is also very large. For some consumers, they do not understand the principle and often spend a lot of money to buy a satisfactory product. How can I buy a high quality vacuum flask?
The first thing to look at is the appearance of the cup. See if the surface of the liner and the outer bladder are evenly polished, and whether there are bruises or scratches;
Second, see if the mouth welding is smooth and consistent, which is related to whether the feeling of drinking water is comfortable;
Third, look at the quality of plastic parts. Not only will it affect the service life, but also affect the sanitation of drinking water;
Fourth, see if the internal seal is tight. Whether the screw plug and the cup fit properly. Whether it is free to screw in and out, whether it is leaking. Fill it with a glass of water for four or five minutes or a few moments to verify that it is leaking. Look at the insulation performance, which is the main technical indicator of the insulation cup.
Generally, it is impossible to check according to the standard when purchasing, but it can be filled with hot water and then feel the hand. If the cup that is not insulated is filled with hot water for two minutes, the lower part of the cup will heat up, and the lower part of the insulated cup is always cool.
