Answer:

A thermos is a bottle with a double-walled container inside of it.
The air between the two walls is sucked out during construction, creating a vacuum.
Instead of containing some kind of heating element to keep hot things hot, a thermos is designed to keep hot things hot by not allowing heat to escape.
