Abstract
A method and closure and container combination for packaging and sealing a commodity in a container that reduces headspace gases, in particular oxygen, allowing the packaged commodity to have a longer shelf life. The method is also useful for reducing stresses on containers that undergo filling at an elevated temperature and/or require in-container pasteurization or retort processes after fill and seal.
