Best 10 Vacuum Flask Factory in China 2026

Introduction to Vacuum Flask

A vacuum flask, also known as a thermos, is a container designed to keep liquids hot or cold for an extended period. It consists of two flasks, one placed inside the other and joined at the neck. The space between the two flasks is evacuated to create a vacuum, which significantly reduces heat transfer by conduction and convection. This design allows the vacuum flask to maintain the temperature of the liquid inside, making it a popular choice for transporting hot coffee, tea, or cold drinks. Vacuum flasks come in various sizes, shapes, and materials, and are widely used in households, offices, and outdoor activities. Vacuum Flask
