As the weather gets colder, everyone has begun the "health preservation" mode. Many people buy various thermoses from supermarkets and the Internet, and the prices vary. The thermos is a fire in winter, which can bring warmth to winter. So, are all thermoses on the market safe?

thermos cup is an item at the entrance, so you must not be careless during the selection and use process, as it may harm your health if you are not careful. So, what kind of thermos will harm our health? Today, Xiaonan will take you to learn more about it.

The first type: the inner liner is not good

Everyone knows that the inner liner inside the thermos is made of stainless steel. Now many bad merchants on the market choose stainless steel of poor quality in order to efficiently produce thermos. In use, thermos such as is equivalent to eating heavy metals.

Then, when buying a thermos cup, you can open the lid of the thermos cup, use the flashlight function of your mobile phone to illuminate the stainless steel inner liner, and try to choose a thermos cup marked with the number 304 or 316. Such a thermos cup is safer.

The second type: the product is unqualified

The name of the thermos cup is definitely a cup that can be insulated. As a thermos cup, insulation is the most basic function. However, many cups are under the banner of "thermills", but in fact they are plastic cups , which are not of the standard material. Such cups will seriously threaten our health.

If you don’t know if your thermos is a thermos that is not of good quality, then you will know if you try it with tea. Pour the thermos with strong tea and leave it for 2 days. After 2 days, if the quilt fades, then this is an unqualified thermos, and it is not insulated.

2. Insulated cup tea

Since ancient times, tea has been the favorite of Chinese people. Friends who love to drink tea know that you must drink hot tea when you drink tea, because the taste will worsen when the tea is cold.
