Well put Wagga. I have a 2 lb 9 oz Garcia canister which I have lugged with me since I bought it 8 years ago because I have peace of mind from both large and small critters and it makes a great seat while I am eating. Somehow ultralight and bear-proof don't mix. Even if the plastic is improved I still think it would be a few pounds in weight because it needs to be a larger diameter then the bear's jaws.
