Mike, I don't have suggestions that match your requirements exactly. I assume that you're on a tight budget?

My default tin for 'just in case' kits is the classic Tim Horton's coffee can. No coating AFAIK, one litre capacity, tight fitting plastic lid, and comes with decent camp coffee as a bonus. I recently got some Nabob tins on sale, also one litre size, that have a big sturdy lip inside the top of the can; I could drill a couple of holes in that lip for a bail and still have a sealed can to carry water using the plastic lid. Personally, I'd rather have two of these than one big can.

In my kits, I put a label on the coffee cans that says 'OK to cook in, ' -- just in case somebody else happens to be using it. They taste a trifle metallic when first boiled, so I prefer to discard the first batch of hot water (fine for washing though).

LOL at Sue's suggestion! I've kept a couple of those big Heineken cans for exactly that purpose. If I was going to use them regularly, I'd scrub out the inside with some fine sandpaper or steel wool and then boil the bleep out of them. The coating isn't thick. I'd use the same routine with 'found' cans in a survival scenario, using river sand as abrasive.
