Once you have one in your life, you'll find it accompanying you to the office, festivals, camping, and even on vacations abroad. How does a thermos bottle work? In a nutshell, they used a double-walled structure that eliminated the air between these walls, creating a vacuum. Heat has difficulty passing through a vacuum, which means that the liquid maintains a roughly constant temperature. In everyday life, people are used to drinking water from a thermos, which is especially common in winter. So, can storing liquids in a Stainless Steel Thermos Flask cause harmful chemical changes in the body?
In fact, simply filling the stainless steel thermos flask with water is non-toxic and will not cause any harm to the human body. The stainless steel thermos is made of double-layered stainless steel inside and outside. The inner liner and the outer shell are combined by welding technology, and the air in the middle layer between the inner liner and the outer shell is extracted by vacuum technology to achieve the effect of vacuum insulation. It has the advantages of good thermal insulation performance, light weight, anti-fracture, anti-corrosion, anti-extrusion, fast heat resistance and convenient operation.
In addition, the stainless steel vacuum insulated water bottle is made of food grade 304 stainless steel. steel to ensure that heavy metal levels, including lead, are not exceeded in the thermos. At the same time, the inner lid of the ordinary stainless steel thermos cup is made of PC material. PC material is boiled in boiling water, tasteless and not deformed. The apron is made of silicone and is also non-toxic. So, are stainless steel thermoses toxic?

Tea contains a lot of tannic acid, theophylline and aromatic oils, as well as a variety of vitamins. If you use a thermos cup to make tea, the tea leaves will be soaked in high temperature water for a long time, which will greatly reduce the nutritional value of the tea leaves and make the tea leaves tasteless. Bitterness, harmful substances in tea will also increase. If the cup is full of milk, it will cause bacterial growth every 20 minutes and the milk will spoil after 3-4 hours. In addition, the constant temperature in the thermos will destroy the vitamins in milk and directly affect physical and mental health.
