Branding: Design choice - Tin can

You can buy baked beans in two formats: in the new-fangled, ring-pull can or the good ol' fashioned grab-yourself-a-twiddly-bit-can-opener, can. Now we all know the latter has its faults. Even the best electric-powered wall-mounted can-opener leaves the lid still attached by two spindly pieces of metal. Things get worse if you use the scissor-action rotating butterfly contraption. And positively diabolical if you attempt to use a Swiss army knife.
