No matter what the weather is, it seems that parents will prepare a thermos cup for their babies. Because I drank too much cold water, I was worried about the child's stomach discomfort.
However, the thermos cups we commonly use are not as safe as imagined. Not only does it not protect the child's stomach, but it may also be "poisonous".
One: There is a thermos cup, and the poured hot water becomes "poisonous" water
I have seen a matter exposed by CCTV before, saying that if we commonly use the thermos cups, if they are used wrong, it is likely that the hot water poured out will become "poisonous" water.
What the hell is going on here?
It turned out that the Beijing Consumers Association purchased a total of 50 kinds of thermos cups from various channels for testing. It was found that there were 19 types of non-conformities, including children's thermos cups.
Because its inner tank contains heavy metals that exceed the standard. If the child uses it for a long time, it will lead to too much heavy metal in the body, which can lead to poisoning.
Heavy metals are also in our human body, and the right amount of heavy metals is good for health. However, if it is exceeded, it may bring great harm.
For example, manganese exceeds the standard.
According to the "GB9684-2011 National Standard for Stainless Steel Products", the manganese content in the cup cannot exceed 2%. If your child swallows too much manganese, it will lead to a decrease in resistance, and may also cause gastrointestinal discomfort, damage, etc.
In addition to causing harm to the body, too much manganese can also lead to memory loss.
A mother next to me said that her children are prone to diarrhea, even if they have been drinking hot water from thermos cups, they still don't see well.
After she saw the thermos cup, she quickly checked the child's thermos cup, and found that the bottom of the cup was rusty. Frightened, she quickly changed the child into a normal ceramic cup.
And after that, the child is really much better.
It can be seen that this type of thermos cup is really unusable.
Two: how to choose the right thermos cup
Since the heavy metal exceeds the standard thermos cup, it cannot be used for children. So how do parents identify whether their own thermos cups are available?
The researchers explain that it is possible to pour saline into a thermos cup. After soaking for a day and a night, if the thermos cup does not appear abnormal, it means that the cup is qualified.
If there are spots or marks on the surface of the cup and in the inner tank, it means that there may be a situation where the metal exceeds the standard, and we still do not use it.
In addition to the cup to buy back the test, we can also use the following methods when purchasing cups, so as not to buy back and find unqualified.
Try to pick the brand, high visibility
Big brands have more stringent controls on quality due to the more mature production lines and the need to maintain their own brands.
Therefore, when we choose the thermos cup, we still try to pick a big brand and a high reputation, relatively speaking, it is more assured.
After all, the products that come out of the workshop are difficult to distinguish whether it is passed, whether the quality is reliable, and whether it can be used with confidence.
The "three noes" products produced by small workshops are likely to be cheaper in order to save costs. In terms of quality, it is difficult to pass.
See if there is a "304" or "316" label
On the inner tank of the thermos cup, the common label is 304. It is inside stainless steel and is of food grade. If the child usually just drinks water and keeps warm, it is enough.
316 will be relatively stable, which is suitable for people who have higher requirements for thermos cup. For example, people who like to make tea, or people who keep warm red date goji berry soup.
Because the 316 material thermos cup is not easy to react with the outside world, so there is no need to worry about other problems.
Therefore, when we pick a thermos cup, we must look carefully to see whether the bottom of the cup is engraved with such a mark. If you have one, you can buy it with confidence.
Look at the tightness
I remember the first thermos I bought, I had no experience at the time, and I bought it and used it. As a result, because the bag was shaking when it was walked, the water that overflowed made the bag all wet.
I examined it closely and found that it was not very tightly connected at the mouth of the cup, resulting in poor sealing water spilling out. Fortunately, it only wet the bag, and the hot water did not burn my hands.
When children drink water, they sometimes like to hold the cup and shake it constantly. Poor sealing of the cup, hot water can easily leak out, may hurt the child.
Therefore, after we buy the cup back, it is best to check how well it seals.
Look at thermal insulation
Thermos cups vary widely. Some cups have a good insulation effect, and the water is still hot after a night. Some have poor thermal insulation, and the water may be cold in a few hours, and the meaning of heat preservation is lost.
Therefore, when we choose the thermos, we also need to see how it performs.
We can pour hot water into the cup and, after a while, touch the temperature of the cup. If you feel a little hot, then this type of cup dissipates heat quickly and has a poor heat preservation effect.
Cups that can generally be kept warm for 6-8 hours are ideal. It is enough for us to use this type.
Cold weather is more compatible with the thermos, but when we choose a thermos for our children, we should still look carefully to avoid the "hot water" in the cup becoming "poisonous water".
Thermos cup containing heavy metals, beware of pouring out hot water becoming "poisonous" water. Let's see, is your child using it?
