I use/own a wonderful all in one container. It is an old aluminum Ovaltine shaker. It is similar to a martini shaker, it has an air tight lid that doubles as a cup, it holds two cups of water, and it is extremely light weight. The downsides to it are that it is delicate, being made of thin aluminum, and the base is kind of narrow which might make it difficult to stand it on some stove tops.
I don't think it would be very good for a water bottle in the capacity that I'd be drinking from it, but it can hold water and you could use it to store extra water to transfer to a more practical water bottle or camelbak.
I have a windscreen that it sits in when I am using it with an alcohol stove, otherwise I just put the lid on, dig a small hole for it, then rake in some hot coals from the camp fire and settle it onto them. The thin aluminum body transfers heat very quickly and efficiently, the lid fits so well I can literally hold the container full of water, upside down with no spillage.
You can sometimes find them on eBay, usually for 15-20 dollars after shipping. I just searched for "Ovaltine shaker" and found several of them for sale. =)
