Insulation Performance

The purpose of purchasing thermo flask water bottle is to keep all kinds of drinks warm for a long time, which is also the ultimate function of all thermos cups. So how to identify the products with good performance in many brands of thermos cup? Usually, we can put a cup of hot water into the thermos cup, and touch the wall of the cup five minutes later. If the surface of the cup is slightly hot, the heat preservation effect of the thermos cup is relatively poor.

 

 

Tightness

The tightness of the vacuum flask water bottle is very important. The sealing of water cups is an issue that most consumers need to consider, because they are likely to carry these thermos cups with them, rather than simply put them on the desk. If there will be tiny drops of water after tightening the cover of the thermos cup, it will not only prove that the sealing sleeve of the thermos cup has quality problems, but also indicate that the heat preservation system of the cup is unqualified.

 

 

Health

It is undeniable that consumers are very concerned about the most basic insulation function when buying bottles, but the health of the insulated vacuum bottle material has also become the focus of attention in recent years. Insulation cup material is not a very difficult content to understand, usually some inferior insulation cup material can be smelled by nose. Usually, the thermos cup with a small amount of heavy metal inside will have a pungent smell.

 

  

Weight

Many people may have paid attention to the weight of the vacuum steel bottles when they were choosing the thermos. They even thought that the heavier the thermos is, the better the quality will have. 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.
