The weather is getting colder, and everyone has gradually started to pay attention to the vacuum insulated flask. Many people have also started to buy the insulated flask bottle. But the vacuum flask we choose may be likely to be harmful to our health. Let's see the following factors that we need to pay attention when choosing insulated thermos bottle.

 

 

Insulation Performance

The performance pursued by the thermo flask water bottle is heat preservation, which is also its main function. How to identify whether the vacuum flask has a good heat preservation function? First of all, we put some hot water in the cup, and then tighten the cup. After 2-3 minutes, we touch the outer wall with our hands to feel whether it is warm or not. Generally, if it is warm, the insulation is relatively poor, while the opposite is good.

Tightness

The tightness of the vacuum flask water bottle is very important. If the tightness is not good, it is likely that the thermos cup will no longer be insulated. How should this be identified? First, we fill the cup with hot water, then tighten the lid and stand the cup upside down on the table for 10 minutes. During this time, you can shake it with your hands. If there are drops of water, it is of poor quality, and vice versa.

 

 

Health

In recent years, as everyone pays attention to health preservation, the health of the insulated vacuum bottle has gradually been recognized. Normally, we can smell whether the vacuum flask material is healthy or not. For example, a vacuum flask with a heavy peculiar smell is definitely not usable, and there may be some heavy metals added to the interior, and the material is problematic. We suggest you Choose 304 stainless steel.

Weight

Many people may have paid attention to the weight of the vacuum steel bottle when they were choosing the thermos. They even thought that the heavier the thermos, the better the quality. In fact, this is not true, because this cup may contain other harmful metals or heavier magnetic sheet. Drinking the water in the thermos cup made of this material will definitely affect our body health.

 

 

Feature

When choosing a stainless thermos bottle, we must also pay attention to whether the cross-section or the surrounding of the cup is smooth, whether it contains flaws, whether there are cracks, and whether it has anti-slip effect in function, after all, things filled with water are easier to slip off. Paying attention to this kind of information can prolong the service life of the vacuum flask.

 

 

Based on the above, we are very easy to choose a stainless thermos flask. In addition, it is recommended that everyone pay attention to the material when choosing a vacuum flask. For example, the material of the lid is designed with food-grade silicone, and the inner container of the vacuum flask should use copper plating, the bottom of the cup should have a non-slip rubber treatment. As long as you choose according to these methods, you don't have to worry about not choosing a good stainless-steel vacuum jug.
