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.
Why does my thermos not stay hot?
Thermos flasks work in two main ways. They insulate by using a vaccum between a double-walled glass vessel and the walls of this vessel also reflect heat as they are silvered. If your flask isn’t visibly damaged (look underneath the plastic cover) then a small crack or defect may have caused the vacuum to fail.
