Ideally, I'd like to find an 8 ounce bottle compatible with the packafeather cap so I can store the bottle inside my Caldera Cone. Anyone know of any brands that would work with a packafeather cap?

Found it!!!!

I don't like what I read about the caution /warning in red:

CAUTION: Fuel bottle may develop internal pressure with changes in altitude and/or temperature. When opening always point the spout AWAY from you and/or any open flame source.

I would not even consider using this type of lid.

I have had a cap similar to it on a bottle of fuel sitting on my table saw. A small rise in air temperature caused the fuel to be pushed up the tube and out onto the surface of the saw. I know what I saw on the saw for sure, serious sighting say the least. :mrgreen: Note: the spout was in the open position when the fuel was forced up and out by it's self.

I may order one of those caps just to see if it functions the way I think it does.

The only way I would use one is if it fit a heet bottle..I always pack my fuel in an outside pocket...and take plenty.

HJ, do me a favor. Fill one of your fuel bottles so the fuel comes to 1/2 inch above the tube extending into the bottle. Cap it and have the spout open. Wait for a few min and then wrap your hands around the bottle to warm it up, don't squeeze it. Watch to see if the fuel will rise in the tube and come out the little doohicky on the spout.

Well then, all is well if there is no tube that extends into the bottle. Yes, sounds like an easy DIY cap with a flip top.

I had a labratory type bottle that had the tube extend to the bottom of the bottle that was sensitive to temperature rise. Had to keep the cap screwed on loose to prevent pressure build up.

The closest thing to those I have seen off the shelf is a stabil bottle (no pointed spout but nice measuring and pouring)

Sudden, those are nice, really nice especially the small size. I use graduated 4 ounce bottles. I made up some mylar labels for the bottles that go with the GoTo stove so my bottles have the graduations in 3/4 ounce increments.
