The Codd marble bottle was born from the need to keep carbonated drinks from going ‘flat’. Originally, effervescent drinks were contained in stoneware bottles, but these allowed the gas to leak and the drink would indeed go flat. Soon, bottlers were using glass bottles but noted that the pressure from the gas within the bottle could force the cork stopper out, especially if the cork dried out. In 1872, then 34-year old Hiram Codd of Suffolk, England solved the problem by inventing and patenting his design for a bottle that used a marble and rubber gasket to seal the beverage within.
