A small thermometer on the side of the thermos, to know the temperature of your drink.

Not exactly what [DesertFox] described, and sort of makes you wonder what the makers were thinking. [jurist, Jan 05 2006]

do you mean inside the thermos? otherwise it's a thermometer.

The readout is on the outside, yes, but the little bulb at the bottom is on the inside. It would be useless to have to open the thermos to see how hot the drink is. Kind of defeats the purpose.

You can get a thermos that plugs in to keep beverages hot - see link.
