The stainless steel vacuum flask is a water container made of stainless steel and a vacuum layer. It has a lid on the top and is tightly sealed. The vacuum insulation layer can delay the heat dissipation of liquids such as water inside to achieve the purpose of heat preservation. There are three ways of heat transmission: radiation, convection and transmission. The silver bottle inside the thermos can reflect the radiation of hot water, the vacuum of the bottle and the bottle body can block the heat transfer, and the bottle that is not easy to transfer heat can prevent the heat convection. The surface is smooth and has no odor. After pouring boiling water, the thermos bottle with no heat feeling can be called a good bottle.
The inside and outside are all stainless steel, refined with advanced vacuum technology, elegant in shape, seamless inner tank, good sealing performance, and good heat preservation performance. You can put ice cubes or hot drinks. At the same time, functional innovation and detailed design also make the new vacuum flask more connotative and practical.Avoid collisions and impacts during use to avoid damaging the bottle or plastic, causing insulation failure or water leakage. Use proper force when tightening the screw plug, and do not rotate it excessively to avoid screw failure. When drinking coffee, tea or beverages frequently, the inner liner will change color. This is normal, and it can be removed with toothpaste and toothbrush.
