For whatever length of time the thermos maintains a food temperature above 135°F, plus an hour or maybe two. You will need to test the temperature-holding capabilities yourself, since that can vary with the type of food, starting heat and the ambient conditions. And you'll need a thermometer to do it.
Pre-heating the thermos with hot water should prolong the appropriate holding time.
The danger range for food safety is 40-140 F in between that range bacteria will grow.
