Yeah, that ought to about do it.

I like plastic since it's light. I've seen the Nalgene one that AFLM linked to at REI. It looks decent.

Problem with a flask with alcohol is that people might think you were drinking the alcohol. I can just see a cop pulling you over: "Sure, that was for your stove, lady. Tell it to the judge."

I bought some little squeeze bottles at REI, but they're only 2 oz each, which is fine for a cup of tea or two on a day hike, but aren't going to last long otherwise. I can't remember what else they have, but it might be worth a visit if there's one in your area.
