The thermos cup hasn't been used for several years. Can it still be used? Many people like to use thermos cups in life. It is said that thermos cups have a shelf life. I sorted out the relevant information about whether the thermos cup can be used after several years. Let's have a look.

The thermos cup has been useless for several years. Does it still work? 1 will not break.

The insulation principle of the thermos cup mainly lies in the vacuum layer, which is easy to be damaged, so try not to put it in a higher place when storing the thermos cup to avoid accidentally touching it in the future. If it falls, it is likely to cause the vacuum layer of the thermos cup to crack, so that the thermos cup is no longer insulated.

When we don't use the thermos for a long time, drying the thermos is the most basic step to maintain the thermos. Detachable fittings in the thermos cup should be disassembled and cleaned separately. After cleaning, wait for all the air to dry before assembling and storing.

Precautions:

1, because thermos cups have heat preservation effect, especially some good quality thermos cups have particularly good heat preservation effect. If you put very hot boiling water in it, it will still be very hot when poured out, so take medicine in a thermos cup to prevent burns.

2. It is recommended not to use thermos cups to hold greasy liquids such as soup. If the soup is not cleaned in time, it will have a serious oily smell. No matter what method is used to remove it later, it is difficult to remove the greasy smell.

3. Don't use steel wire to clean the thermos cup, which will damage the cup body inside the thermos cup and affect the insulation effect, so don't use the thermos cup to hold things that are difficult to clean.

4. Pay special attention when using the thermos cup. Don't drop the thermos from a high place. Hold it steady when you hold it. If you are not careful, it is easy to break the lid of the thermos cup or deform the cup body.

Can the thermos cup still be used after several years of uselessness? Will it not keep warm if you don't use it for a long time?

Generally speaking, the insulation effect of the thermos cup will not be weakened after a long time, but the premise is that the quality of the thermos cup you buy must be guaranteed. Once you buy inferior ones, you don't have to put them away. The insulation effect will be completely gone after using them twice.

How long can I keep the thermos cup?

Because most of the thermos cups sold in the market are stainless steel, they can be preserved for a long time as long as they are placed in a dry environment and do not fall off. Just take it out and scald it with hot water when you use it.

How to keep the thermos cup for a long time?

The thermos cup is a common item in life. If you don't want to keep it, you must wipe off the water stains on its liner. In addition, in order to prevent odor or stains, it should be cleaned after use and fully dried. Because the use of impure water will leave red spots similar to rust, it can be soaked in warm water and diluted vinegar for 30 minutes and thoroughly cleaned.

The thermos cup hasn't been used for several years. Can it still be used? 3 use a thermos cup, not five kinds of "water".

First, tea. This is not an alarmist. Drinking tea in thermos for a long time will lead to many diseases such as digestion, cardiovascular and cerebrovascular diseases, nervous system and hematopoietic system. Because making tea in a thermos cup is actually soaking tea in high-temperature and constant-temperature water for a long time, just like frying tea with warm fire, a lot of vitamins in tea are destroyed. At the same time, the aromatic oil in tea volatilizes, and tannic acid and theophylline are leached in large quantities. Reducing the nutrient content of tea is a trivial matter, and heavy metals may be released, which is harmful to the health. Many middle-aged and elderly friends around me have this habit. In fact, this is undoubtedly increasing the risk of illness for themselves.

Second, all kinds of acidic drinks and juices. The inner container of the thermos cup is basically stainless steel. Because of its high melting point, it will not release harmful substances due to high temperature melting. However, stainless steel is most afraid of strong acids. If the acidic substance is left for a long time, heavy metal components will be separated from its inner container. Many office workers don't have time to have breakfast in the morning, so they are used to bringing fruit juice to the company in thermos cups, which is also very harmful to their health.

Third, milk and soybean milk. If these two things are stored in a thermos for a long time, microorganisms will multiply rapidly, leading to gastrointestinal diseases such as corruption, diarrhea and abdominal pain. In addition, the nutrients such as vitamins contained in it will also be destroyed. Many parents like to take their children to school in this way. In fact, insufficient nutrition is bad for their health.

Fourth, traditional Chinese medicine or other granules. It sounds like a good way to store traditional Chinese medicine in a thermos, but in fact, the decocted traditional Chinese medicine dissolves a lot of acidic substances, which can react with the chemicals contained in the inner wall of the thermos and dissolve into soup, thus causing adverse effects on the body. Usually, it is best to drink Chinese medicine in pottery or enamel containers.

Fifth, salty liquid. Because the inner container of the thermos cup is generally sandblasted and electrolyzed, the electrolyzed inner container can avoid the physical reaction after water directly contacts with stainless steel. However, salty liquids, such as salt water, are corrosive and may cause damage to them, so it is not suitable for long-term storage.

In fact, the best function of a thermos cup is to keep warm, cold or hot. It is very good to be a tool for holding water. Don't expect it to give you health care. In addition, there are many kinds of materials for thermos cups on the market at present. If you have to soak something in it, you still need to know more about its material characteristics.
