Abstract
Container closures wherein at least one void comprised in the closure is at least partially filled with a gas or gaseous mixture which by composition or pressure is different from air are disclosed. The oxygen content of said gas can be lower than the oxygen content of air. Through use of such closures for sealing closed containers, the amount of air and therefore oxygen that enters the closed container through closure desorption can be effectively controlled, changed, or even largely eliminated.
