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.
Not sure I'd like to drink the contents of the one under the downtube tbf..
