      Can openers were invented 48 years after cans....
      The tin canister, or can, was invented in 1810 by a Londoner, Peter Durand. The year before, French confectioner, Nicolas Appert, had introduced the method of canning food (as it became known) by sealing the food tightly inside a glass bottle or jar and then heating it. He could not explain why the food stayed fresh but his bright idea won him the 12,000-francs prize that Napoleon offered in 1795 for preserving food. Durand supplied the Royal Navy with canned heat-preserved food while Appert would help Napoleon’s army march on its stomach.

       Cans were opened with a hammer and chisel before the advent of the can opener.

      Tin canning was not widely adopted until 1846, when a method was invented to increase can production from 6 in an hour to 60. Still, there were no can openers yet and the products labels would read: “cut around on the top near to outer edge with a “chisel and hammer.”
      The can opener was invented in 1858 by American Ezra Warnet. There also is a claim that Englishman Robert Yeates invented the can opener in 1855. But the can opener did not become popular until, ten years later; it was given away for free with canned beef.

      The well-known wheel-style opener was invented in 1925. Beer in a can was launched in 1935. The easy-open can lid was invented by Ermal Cleon Fraze in 1959.

      Since 1972, some 64 million tons of aluminum cans (about 3 trillion cans) have been produced. Placed end-to-end, they could stretch to the moon about a thousand times.

      Still, cans represent less than 1% of solid waste material - about one quarter of all cans are recycled. Worldwide, some 9 million cans are recycled every hour. Which is good news, considering that it takes a can about 200 years to degrade if you bury it.
