However, making tea in a thermos cup

There will be an explosion!

Recently, 23-year-old Xiaoxue

I met this accident:

Just because you have soaked red dates in a thermos for a long time,

When unscrewing the thermos cup, the lid of the cup suddenly exploded.

Causing Xiao Xue's eyeball to rupture.

August 2020 1 1 8: 00 pm,

Fujian Second People's Hospital,

Xiaoxue was rushed to the emergency department by her family.

Her right eye is closed and there is blood oozing out.

I screamed with pain.

At the time of the visit,

Her right eye is completely blind.

The family said that ten days ago,

Xiaoxue soaked the red dates in a thermos and forgot to drink them.

On the night of the incident,

Xiaoxue wants to unscrew the thermos cup, but the lid is particularly tight.

She twisted it a few times,

I didn't expect the lid of the cup to pop up suddenly and hurt my eyes.

The doctor performed debridement and suture for Xiao Xue overnight.

She is still under observation in the hospital.

I don't know if you can regain your sight.

A good thermos cup

How could it suddenly "explode"?

Expert explanation

The thermos bottle has good sealing performance.

Soak red dates, boat-fruited Sterculia, etc. In the thermos.

Storage time is too long after water absorption.

Will produce fermentation gas.

Increase the air pressure in the cup

It is dangerous to suddenly open the lid at this time.

↓↓↓

■ When using a closed cup, it is best to preheat it with hot water before pouring it out, and then add hot water to avoid the sudden increase of air pressure caused by excessive temperature difference and the "gushing" of hot water. When opening and closing the cup cover, you can carefully open and close the cup cover repeatedly, and then tighten it after releasing gas.

■ In addition, effervescent tablets will quickly release a large amount of carbon dioxide after contact with water, and a large amount of gas will be compressed in a closed narrow space. The longer the time, the more gas will be released, which will cause pressure on the bottle wall from the inside, form instantaneous high pressure, and also cause "bursting".

Uncle Ann reminds me here.

When everyone makes tea in a thermos cup,

It's best to soak and drink now

Be careful when opening and closing the thermos cup.

Paying attention to details is safer ~
