Four or five of us bought cans at hay days. I lost two gas caps and a friend lost one of his. We watched the caps making sure they were tight, they must be sensitive to temperature changes. I talked to mountain addiction and they were not willing to help out. They will happily sell you new one for five bucks plus freight. If they would fix the mold for the can and put the lock ring back on the can all the problems would go away.!
