Abstract: This invention relates to containers for the storage and dispensing of materials which evaporate, deteriorate or oxidize when exposed to air. A reusable dispensing receptacle system with preservative attributes is comprised of four essential components. The invention by combination includes a vessel, a follower or partition to separate contents from direct exposure to convecting ambient void air within the vessel, a volumetrically adjustable insert to displace ambient air from the vessel, and a lid. The system is simple in construction, and intuitive in use. The system is easily handled and is intended for use in any setting. The system provides a solution for extending the freshness and usability of liquid or pour-able dry contents after the seal of an original package has been broken. This combination eliminates convoluted, intricate, and costly means in favor of those that are reliable, simple, re-usable, and affordable. These four components may be combined to further simplify the invention.
