Keeps heat! Keeps cold! Resistant to falling! Waterproof! 13 popular thermos cup reviews you must read

If a cup of milk tea is what wakes up autumn, then a thermos cup with wolfberry is what embraces winter...

Children go to school, workers are at work, middle-aged people drink tea... As much as Chinese people love to drink hot water, they cannot do without thermos cups in winter.

Here we are, the "Thermos Cup Review" that fans and friends have been looking forward to, we have arranged it——

The sample fee is 2202.43 + the testing fee is 4494.40 (public price) = a total of 6696.83 yuan. Based on the four major evaluation dimensions, the final recommendation is:

Evaluation is not easy. If you find this article helpful, please share and support it!

As the highlight of the evaluation, for the thermal insulation evaluation dimension alone, we simulated daily usage scenarios and conducted 4 experiments.

How many people start their work and study by getting a cup of hot water? When you are tired, open the thermos and take a few sips, it is warm and considerate.

We simulated people's drinking water at room temperature: fill a thermos cup with hot water, pour out 20ml every hour, and record the temperature change over a 4-hour period. The results are as follows:

Note: The smaller the △t value, the better

Based on the experimental data, the temperature difference of the 13 samples before and after 4 hours did not change much.

Those who pursue heat preservation effect can choose: No. 7 Tiger P children's model, No. 10 Elephant Y, No. 6 Cup J Bear children's model, No. 2 Therapist, No. 11 Little M, No. 8 Haas.

Taking into account the severe cold climate in the north in winter, we also went to the high and low temperature and humidity alternating test laboratory with a cost of 400,000 yuan to test the heat preservation effect of the thermos cup after 4 hours in an environment of minus 40℃.

In extremely cold conditions, the temperature difference of the thermos cup changes significantly: among them, No. 7 Tiger P children's model, No. 10 Elephant Y, No. 6 Cup J Bear, and No. 2 Chef M perform better, and the temperature can be basically maintained within 20℃ in 4 hours.

Note: The smaller the △t value, the better

In order to make the usage scenarios of the thermos more diverse, we also poured the ice-water mixture into the thermos and sealed it, and tested the cooling effect after it was placed at room temperature for 6 hours.

According to the test results, No. 11 Small M, No. 8 Haas, No. 9 Tiger P and No. 10 Elephant Y have better cooling effects.

Note: The larger the △t value, the better

In addition to the above 4 models, No. 4 Xi L, No. 1 Fu G, and No. 13 Miscellaneous Brand 2 all have some ice left, which are suitable for friends who like to serve iced drinks.

I know that for some friends, the thermos cup is not broken by "use" but by "falling".

In order to select the "durable" contestants, we filled a thermos cup with boiling water, placed it on a floor tile at a height of 0.8 meters, and let it drop freely three times.

For samples that did not break or have their lids fall off after three attempts, the temperature was recorded again after 4 hours.

Note: The smaller the △t value, the better

For the 7 products that passed the drop test, the temperature changes before and after 4 hours were not very large.

Judging from the condition of the thermos cups after falling, No. 5 MingC YouP and No. 3 LeK LeK performed well; No. 11 XiaoM and No. 2 ShanM Shi were also good.

For those who use thermos cups on a daily basis, the biggest disaster is water leakage! If the cup is filled with tea, coffee, etc., people can only cry for help.

We simulated the situation of putting the thermos cup in a bag and shaking it up and down: holding the thermos cup with both hands, swing it from 45° upward to 45° downward for 10 times, and checked whether there were any water stains or water spots.

The results showed that only the No. 11 small M had a slight leak. After analysis, it was probably caused by the large gap in the silicone opening inside the top cover of the sample.

Do you remember the “Stainless Steel Material Identification” event last winter?

We have tested more than 2,000 stainless steel products for fans across the country, including pots, pans, and of course, the most common are thermos cups.

For this thermos bottle review, we used an XRF scanner in conjunction with a handheld X-ray fluorescence spectrometer to determine the stainless steel grade of the sample.

The results are as follows:

Judging from the test results, the material of the big-brand thermos is consistent with the claims and is relatively regular; while the shells of the two unknown-brand thermos are made of relatively cheap high-manganese steel (201), which is prone to rust.

The inner liner of sample No. 12 was stamped with 316, but it turned out to be 304 stainless steel. It is easy to guess why the merchants would "cheat" like this, and it is nothing more than the word "profit".

Although both 304 and 316 are austenitic stainless steels, the main difference is that 316 stainless steel has a higher nickel content and additional molybdenum.

The price of molybdenum is relatively high, so the price of 316 stainless steel products is also higher. But if it is only used as the liner of a thermos cup, 304 is enough, and you don't have to worry about the difference between the two.

We tested the coating adhesion of the thermos bottle in accordance with the national standard, that is, whether the paint is easy to fall off.

The results showed that all 13 thermos bottles met the requirements, with a strong coating and a paint surface that was not easily damaged. In addition, we also tested the odor according to the national standard, and the results also met the standards.

But some friends left us messages saying that the odor after filling with coffee or milk lingers for a long time and is difficult to remove.

The method of “removing odors” is also very simple, that is, it is best to only fill the thermos with water!

This is not the case of "listening to your words is better than speaking them alone"!

If hot milk or milk tea is kept warm for too long, the acidity of the milk will change, accelerating the reproduction of bacteria.

Try not to drink milk that has been kept warm for several hours, otherwise diarrhea is a minor problem and may also cause acute gastroenteritis

Moreover, this type of unique-tasting beverage will cause the silicone sealing ring, plastic lid and other tiny microporous materials in the thermos to absorb the odor, which is very difficult to remove.

Based on the above evaluation dimensions, we recommend No. 2 Shan Mshi (adult version) and No. 7 Tiger P (children version). You can also choose products that perform well in individual evaluations according to your actual needs.

In fact, this review can be regarded as a conclusion to last year’s “stainless steel material identification” activity which cost more than 100,000 yuan.
