In another embodiment, the closure comprises a gas containing reservoir, a membrane and a barrier layer, said membrane allowing an at least partial exchange of gas between the inside of said reservoir and the inside of said container, and said barrier layer at least partially preventing exchange of gas between the outside of said closure and the inside of said reservoir.
