Several misunderstandings when buying a thermos cup

Regardingthermos cups, most consumers have such misunderstandings that they buy bad thermos cups or they are too expensive. Below, let’s take a look at some misunderstandings when buying a thermos cup:

The heavier the thermos cup is, the better. In fact, the reason why the thermos cup is heavy is because the thermos cup manufacturer adds other things to it during production, such as magnetic sheets, other debris or some insulation materials. If the thermos cup you buy weighs much more than others, and you can clearly feel something moving when you shake it, then the thermos cup is definitely not vacuum. Therefore, it is not good for a thermos cup to be heavier. Although it may have a heat insulation effect, it is definitely not as good as a vacuum thermos cup.

Branded thermos cups are reliable. Some consumers will identify the brand and think that branded thermos cups are reliable. However, compared with ordinary thermos cups, brand thermos cups are indeed more expensive. When buying a thermos cup, it is better to look at the cost-effectiveness. It doesn’t matter whether it is a famous brand or not. As long as it is affordable and has good thermal insulation effect, a thermos cup is best. It is best not to go to the supermarket to buy a thermos cup. The quality and price of thermos cups in supermarkets vary greatly. If you want to buy thermos cups, it is best to find an agent in the country of origin of the product. Firstly, the quality is guaranteed, and secondly, the price will be much cheaper than in supermarkets.The body of the thermos cup can cover your hands. In fact, thermos cups that can cover your hands are not high-quality thermos cups. Most of these thermos cups are not vacuum, so heat will escape.

Which thermos cup material will cause harm to the human body?

Currently, most of the thermos cups on the market are made of stainless steel, and the other material of the thermos cup is glass. In fact, to determine which thermos cup material has a greater impact on the human body, you only need to look at the inner tank. The liner is what really comes into contact with our drinking water and is also the most direct way of transmission. Generally speaking, regularly produced thermos cups will not cause harm to the human body, but it must be said which one is more harmless, that is, the glass thermos cup will be safer. Now, let's analyze it: The reason why glass thermos cups are safer is because glass is a very stable substance, which means that many undesirable impurities contained in it will not leak out during the production process. The stainless steel of stainless steel thermos cups is slightly different. Stainless steel is a metal composite, and the substances it contains are relatively active substances. Some impurities will inevitably appear during the production process, and these impurities will be somewhat harmful to the human body. The above is from the root cause, but the stainless steel thermos cups produced by regular manufacturers use materials that meet national standards and are generally not harmful to the human body. It is inevitable that there will be some inferior stainless steel thermos cups on the market, and such thermos cups cannot be guaranteed to be equally safe.

Stainless steel thermos cups that are not insulated are very harmful

Regarding the stainless steel thermos cup, consumers must have encountered such a situation, that is, the stainless steel thermos cup they just bought stopped being a thermos cup after being used for a period of time. Sometimes we are too lazy to investigate, so we just use the stainless steel thermos cup as an ordinary cup. In fact, when the stainless steel thermos cup is not insulated, it should be discarded, especially those thermos cups that have not been used for a few times. Some low-quality stainless steel thermos cups not only fail to keep heat, but can also cause diseases. For the safety of your family and yourself, never use stainless steel thermos cups that do not keep heat. Of course, it is best to buy a thermos cup with guaranteed quality when purchasing. Insulated cups made of stainless steel are actually harmless, but some unscrupulous merchants on the market produce counterfeit and inferior products that pretend to be non-vacuum and pretend to be vacuum. The inner liner and outer shell of the thermos cup are also made of thinned stainless steel. And some stainless steel materials are even toxic, so they are very dangerous. Industry insiders say that any stainless steel thermos cup with rust or abnormality in the inner tank is likely to be made of inferior or toxic materials, so do not buy and use it.
