Vacuum Flask

The vaccum flask is generally a water-filled container made of ceramic or stainless steel plus a vacuum layer. The top is covered and the seal is tight. The vacuum insulation layer can delay the heat dissipation of the liquid such as water contained inside to achieve the purpose of heat preservation. The appearance is smooth and odorless. After injecting boiling water, the cup with no heat can be called a good thermos bottle. It is made of stainless steel inside and outside, and is refined by advanced vacuum technology. It has elegant shape, seamless liner, good sealing performance and good thermal insulation performance. Ice cubes can be placed, or hot drinks can be placed. At the same time, functional innovation and detailed design also make the new thermos more connotative and practical. Avoid collisions and impacts during use to avoid damage to the cup or plastic, resulting in insulation failure or water leakage. When tightening the screw plug, the force should be appropriate. Do not over-rotate to avoid the screw bolt failure. When drinking coffee, tea or beverages regularly, the liner will change color. This is normal. Use a toothpaste to remove the toothbrush.
