Eric Clutton sells a plastic squeeze bottle for around $10 that has a brass metal valve on the end, probably 8-10oz. I filled it several months ago and the ether content is still high enough to hand start my Schlosser .25cc. These are really nice when you want to just pull an engine off your shelf and run it a bit for fun but not have to mess with the whole fuel can routine.

Highly recommended-I use one for my Bug-Out-Bag to store alcohol for my stove, it gets smashed and beat up a lot and has never leaked.
