Self-heatable Lunchbox

 Lunchbox that heats or warms up your food

Why should we always have cold food in our lunchboxes?

If we have a self-heatable lunch-box, imagine the comfort that would bring to picnics, outdoor lunches, especially in colder climates.

As for the mechanics of how it works, well that's why I'm not an inventor. I suppose any safe, effective means of heating it up would be okay. Might work like a mini-oven or mini-microwave-oven. Could be powered by batteries with optional plug. Or by some other (chemical?) way of generating heat perhaps...

Cool. Does look like what I call a "Thermos." [bristolz, Apr 01 2002, last modified Oct 04 2004]

       I use a food flask. The food is still piping hot at lunchtime.

       Food flask? I've not heard that term before. Is it like a Thermos bottle in design (which I *think* are intended for liquids).   

       A lunchbox outfitted with a Peltier device would probably work for making a heatable lunchbox.

       Yes, they're similar to a thermos flask but shorter, and fatter, with a wide brim so you can get a fork or spoon in there. You can either eat straight out of the flask or pour it into the bowl provided.

       I like it, kind of like the bags the pizza boy uses to keep your pizza warm.
