A cannister general refers to a metal container. So, it is not quite correct to call it cannister. But it is easy to understand how that misunderstanding could occur.
Actually, I think this person actually used the word 'canister' which is not a container at all but has something to do with ammunition. So, I thought I would point out all of this in one post.
