Childproof Lids

Claudio was an engineer by birth; his father was a civil engineer in Rome, and we all know the reputation of Roman civil engineers - their roads and aqueducts were the best in the world! Claudio made a prototype cap in metal, coming up with the 'double-lock' system that we know today. With partner Gavin Park he refined the prototype until he had a working model which they then began manufacturing in plastic. They registered their patent, a process they describe as very costly, and then set about licensing their idea. The patent to their design has now lapsed, but whilst they had it they licensed the manufacture of their childproof lids to an American company, who manufactured millions of them
