Hey Miner, we think alike.

I cut the top off a 500ml thin-walled stainless steel bottle, put a wire bail on it and used the container to hold the Shelter Component in my Winter PSK.

Pictures of the kit and use in the field can be found in this post from last winter.

The thin metal was hot and a little sharp against my mouth but it worked OK. I would rather have a rectangular shaped tall pot as it would be flatter in my pocket, but this cylinder shape is useable because it is fairly small in diameter.

Still searching for the perfect PSK container.
