is it beyond the realms of possibility to just put the sugar containing drinks cans inside a plastic sandwich bag, ziplok, whatever and tie the top. 2 cans in plastic bags in the cooler doesnt matter if you can see or read braille or not  . foolproof and safe and you will be able to recycle  /reuse existing plastic bags and thus save a dolphin
