Abstract
A closure for a container, such as, for example, a wine bottle, is provided. In one embodiment, the closure includes an oxidant releasing agent that is adapted to release oxygen into an interior portion of the container according to a predefined desired profile. In another embodiment, the closure comprises a gas containing reservoir, a membrane and a barrier layer, the membrane allowing an at least partial exchange of gas between the inside of the reservoir and the inside of the container, and the barrier layer at least partially preventing exchange of gas between the outside of the closure and the inside of the reservoir.
