Get a VP Fuel can. They don’t stack well but they are dead simple. The spout is just a hose. We use them at the track and never spill more than a drop. The other option is removing the spring from the newer press-on spouts. They all have a o ring that adds enough tension to keep the spout closed even without the spring. So then you can push it in to open, and leave it open, or pull it out until it locks and keep it closed.
