1. Vacuum flask

   A vacuum flask (also known as a Dewar flask, Dewar bottle or thermos) is an insulating storage vessel that greatly lengthens the time over which its contents remain hotter or cooler than the flask's surroundings. Invented by Sir James Dewar in 1892, the vacuum flask consists of two flasks, placed one within the other and joined at the neck. The gap between the two flasks is partially evacuated of air, creating a near-vacuum which significantly reduces heat transfer by conduction or convection. Vacuum flasks are used domestically, to keep beverages hot or cold for extended periods of time, and for many purposes in industry.

1. vacuum flask

   A vacuum flask is a container specifically designed to maintain the temperature of its contents, keeping cold items cold and hot items hot for prolonged periods of time. This is achieved by double-walled construction with a vacuum between the two walls, which minimizes heat transfer between the inside and outside of the flask. The inner and outer walls are usually made of materials such as glass or metal and often feature a reflective coating to further minimize heat transfer.
