Is there a difference between vacuum bottle and non-vacuum insulated cups? What cups do people usually use? Let’s analyze this question together. In fact, there is a big difference between insulated vacuum bottle and stainless steel cups. The stainless steel cups we usually use are basically insulated vacuum bottle.
What are the differences between vacuum insulated cups and ordinary thermo–flask cups?
The main differences between vacuum insulated cups and ordinary thermo-flask cups are the materials, thermal insulation performance, touch temperature and working principles.
(1) Thermal insulation performance of vacuum insulated mug and ordinary thermo–flask cups
A vacuum insulated mug is a container that can hold water and can prolong the water temperature time. Its characteristics are cold and heat preservation.A vacuum insulated mug with a high vacuum insulation can keep water warm for up to 10 hours.
Ordinary thermo-flask cups have lower thermal insulation performance and stronger heat dissipation than vacuum cups. The heat retention ability generally lasts for about two to three hours.
In short, a vacuum flask can insulate heat, so the cup body will not heat up after being filled with boiling water, while a thermo-flask cup will become very hot after being filled with boiling water.
(2) Materials of vacuum flask and ordinary thermos flask
A vacuum flask is a container that can hold water and keep the water temperature for a longer time. It is mainly made of stainless steel and then added with a vacuum layer.
A vacuum flask is just a cup body made of stainless steel with a vacuum layer. The vacuum insulation layer can delay the heat dissipation of the liquid such as water inside to achieve the purpose of heat preservation.
Ordinary thermos flasks have a variety of material choices, mostly stainless steel, ceramic, plastic, glass, and purple sand.
(3) Working principles of vacuum flask and ordinary thermos flask
A vacuum flask is generally a water container made of stainless steel and a vacuum layer. It is made of double layers of stainless steel inside and outside. The inner liner and the outer shell are combined by welding technology, and the air in the interlayer between the inner liner and the outer shell is extracted by vacuum technology, which is used to achieve the effect of vacuum insulation.
Thermos cups are developed from thermos bottles. The heat preservation principle is the same as that of thermos bottles, but people make bottles into cups for convenience.
The silver lining of the thermos cup reflects the radiation of the hot water. The vacuum between the cup liner and the cup body can block the transfer of heat, while the bottle that is not easy to transfer heat can prevent heat convection.
(4) The price of vacuum thermos cups and ordinary thermos cups
The price of vacuum thermos cups is more expensive. Many people like to buy vacuum thermos cups. Especially the best companion for outdoor activities. It can keep our water cold for several hours.
The ordinary thermos cups sold on the market generally only have the effect of heat insulation. After filling with hot water, the heat preservation time is usually about two to three hours. The price of such ordinary thermos cups is far different from that of vacuum thermos cups.
When buying, you should open your eyes and carefully identify the merchants of thermos cups. Generally, the safety and heat preservation performance of such cheaper thermos cups cannot be effectively guaranteed.
(5) The touch of vacuum flasks and ordinary flasks
Pour boiling water into the flask, and you can feel the difference by touching the outside of the flask after one minute: the one that gets hot is not a vacuum flask, but just an ordinary simple flask; the one that does not get hot is a vacuum flask.
A vacuum flask can generally keep warm for more than 6 hours, and the one with a high vacuum rate can keep warm for about 10 hours. We, FuWinn, have been specializing in the insulation industry for several years, and the vacuum flasks we produce can keep cold for more than 8 hours.
Is there anything we should pay attention to when using a thermos stainless steel water bottle?
Before use, clean the inside and outside of the thermos stainless steel water bottle with a neutral detergent in warm water. To achieve the best heat preservation or cold preservation effect, it is recommended to add hot or cold water for preheating or precooling. Adding ice cubes will have a better effect when keeping cold. To prevent leakage, tighten the switch and lid clockwise when the flask is tilted.
A vacuum flask is much better than a thermos stainless steel water bottle. If you want an ideal vacuum flask, you can contact FuWinn. Free sample can be supported for you to test the quality.
