When filling boiling water with a silver inner tank thermos cup, you should pour a little preheating first, because the silver texture is soft, and a large amount of boiling water is suddenly introduced, and the inner tank is likely to be deformed due to the influence of thermal expansion and cold contraction.
I guess what you said is a sign of the deformation of the inner tank, and this kind of silver utensils made of sterling silver must have its disadvantages if it has its advantages.

The sound of the seam between the inner tank and the cup, boiling water is the sound caused by the heat of the inner tank causing air to come out of the seam.

The characteristics of sterling silver cups have led to its inconvenience in our lives, and silver has three major characteristics: high thermal conductivity, easy oxidation, and soft texture. We also need to pay attention to certain skills when using, otherwise it will bring some unnecessary troubles.
1. Pour boiling water directly into the ordinary thermos cup when you use it, but it is not good to pour boiling water directly into the sterling silver cup. Because although silver is also a metal, the texture is relatively soft, if you pour boiling water directly when using, the silver liner may be deformed due to heat expansion and cold. Therefore, you need to pour a little boiling water to shake and preheat before use.
Preheat before pouring boiling water.
2. The silver itself is easy to oxidize, if the water quality remains in the inner tank after use, it will accelerate the oxidation of the silver inner tank, and the color of the inner tank wall will become dark and yellow after oxidation, so immediately after use, wipe the inner tank with a dry rag, and put it in a dry and ventilated place when not in use.
Silver cups. Of course, when using the sterling silver water cup, it is necessary to pay attention to the prohibition of contact with acid, alkali and strong corrosive substances, and at the same time, it is not suitable to clean and collide with the surface of the inner tank with sharp and hard objects. Before putting it away, you need to gently wipe the water from the cup with a dry cloth or paper towel and air dry.
When used for non-drinking purposes, the time for soaking water in the water cup should be more than an hour.
I hope this helps, thank you for your interest!

Abstract 1, look at the cup mouth: the sterling silver liner is made of silver sheets using a stretching machine, and the silver liner is directly inlaid into the cup shell during the production process, and the silver-plated liner is only plated with a layer of silver by electroplating process. On the rim, the silver-plated ones generally do not extend to the rim, while the sterling silver liner is flush with the rim.
2. Surface smoothness: The surface of electroplating products is relatively smooth due to its process performance, such as silver rings and silver bracelets because of the needs of appearance. The silver liner thermos cup is used for drinking water, and the electroplating process is extremely harmful to the human body (electroplating is a very polluting process).
Therefore, the surface of the silver-plated liner will be relatively smooth, and there is no obvious friction when touched by hand, while the sterling silver liner is made with a silver sheet integrated stretching process, although it will be polished and polished in the later stage, it will still feel a little grinding.
The difference between a thermos cup silver cup sterling silver liner and a silver-plated liner.
1. Look at the cup mouth: the sterling silver liner is made of silver sheets using a stretching machine, and the silver liner is directly inlaid into the cup shell during the production process, and the silver-plated liner is only plated with a layer of silver by electroplating process. On the rim, the silver-plated ones generally do not extend to the rim, while the sterling silver liner is flush with the rim.

The silver liner thermos cup is used for drinking water, and the electroplating process is extremely harmful to the human body (electroplating is a very polluting process).
Therefore, the surface of the silver-plated liner will be relatively smooth, and there is no obvious friction when touched by hand, while the sterling silver liner is made with a silver sheet integrated stretching process, although it will be polished and polished in the later stage, it will still feel a little grinding.
Will silver-plated cups and sterling silver cups turn black in contact with 84 disinfectant water?
Brother, 84 is sterilized by the principle of oxidation, congratulations Your cup and 84 have oxidation reaction, so it turns black, go to the silver point to clean it, but it will dissolve the surface of the cup, that is to say, it will become thinner, but the change is very small. After washing, it will be as bright as new.

No matter what material the thermos cup is made, it is not suitable for making tea.
Thermos cup tea, will make the tea soaked in high temperature, constant temperature water for a long time, just like with warm fire decoction general, a large number of vitamins in the tea are destroyed, aromatic oil volatilization, tannins, theophylline a large number of leaching, not only reduce the nutritional value of tea, but also make the tea juice fragranceless, tea bitter taste, and even because the steeping time is too long, tea may release heavy metal substances, harmful to human health.
At the same time, the high water temperature will also make the aromatic oil in the tea volatilize rapidly, reducing the fragrance of the tea.
If you take into account the heat preservation effect, you can brew hot tea liquid in a ceramic cup and other utensils, and pour it into a thermos cup after removing the tea leaves, so that you can drink hot tea at any time.
In winter, it is undoubtedly the best choice to use a thermos cup to fill hot water, if you use an ordinary cup to fill hot water, it will become cool for a while, and the water temperature can be maintained for a long time with a thermos cup, and the better water temperature can be kept warm for more than 12 hours, it acts like a warm pot, so the boiling water in the thermos cup is still hot the next day, but after a night, the boiling water becomes overnight water, so can the water in the thermos cup be drunk overnight? >>>More
Choose the plastic material of the lid.
The body of each plastic container (generally at the bottom of the plastic container) has a small ID card, a triangular symbol, the triangle has 1-7 numbers inside, each number represents their production materials, "No. 1 PET", "No. 2 HDPE", "No. 3 PVC", "No. 4 LDPE", "No. 6 PS", commonly used in the production of mineral water bottles, carbonated drink bottles, cleaning bath product containers, decoration materials, toys, stationery, instant noodle boxes, fast food boxes, plastic wrap, plastic film, etc. >>>More
The stainless steel thermos cup can be scrubbed with some detergent with a softer cloth, and then scalded with boiling water. >>>More
There are a lot of them, the most common ones are Hals, Sillot, and Lock, which can be bought for dozens of dollars. There are also Japanese thermos, Zojirushi, etc.
The thermos cup is very convenient to see, in fact, if it is not used properly, it will also bring us danger. >>>More
