Meh, it's fine. Lid keeps the dirt out so the contents are safe. Take the lids off, transfer to clean bottle, jobs a good'un. It ain't perfect but it's fine
Edit: oh, just clocked that it isn't a bottle haha. When I'm gasping for water up a hill I'd probably try to take a swig in my delirium. What even is it? Fire extinguisher? CO2? I've no idea
Edit: ohhh it says Trangia on it, fuel I guess then. Did I learn nothing from video games? Red bottles are always explosive.
I just drink from one or two then when I finish one I tip the contents of a dirty ones into it. I can only reach some of them anyway so not like I'd be able to drink from the rear ones or under DT. Saves a bit of time if you can keep them all clean in the first place though and just swap the whole bottle over.
