This one is reasonably elegant @ 1 oz. exactly: (It saves almost 2 oz. for my 2l Titan Ti-tri packed)
For use with the alcohol burner, you replace the tennis lid with the stove (inverted) and it sits rather snugly, although a strap would be in order to keep it together well. I also have a racquetball container that may work even better, although it is a bit more snug, so it wouldn't fit the alcohol burner.
(edit: The racquetball container is PET #1 plastic and comes in at 2.6 oz. w/ lid, which is too heavy in my book; the Penn tennis ball container is actually #7 plastic, which can be questionable for potability, rather than PP for the Trail Designs container.)
