Although in general I prefer using solid fuel with my Caldera Cone, I do sometimes use meths with a 12-10 stove. As mentioned in the comments of a previous post I don't like the taint of meths, so I use the method below for transporting the fuel.
I'm probably not the first person to come up with this solution. This is a very old 500ml Platypus, well past it's best for drinking water, but still gives good service transporting meths. It weights 19g empty with the pullcap shown, (salvaged from a soft drinks bottle) I like the match as well! So durable, light, cheap and takes up less space as you use your fuel...what's not to like!?
