Abstract

An apparatus may be utilized for sealing a vessel and for providing various mechanisms for preserving and maintaining freshness of the vessel's contents. In one embodiment, the apparatus prevents a premature oxidation process by enabling a vessel to be filled with contents without compromising the seal of the vessel. Further, the apparatus eliminates the necessity of opening the vessel during the dispensing process, thereby maintaining the vessel's seal while emptying the vessel's contents. The apparatus may be initially purged of ambient air and oxygen prior to filling the vessel with contents further reducing premature oxidation by reducing a substance's oxygen contact as substances initially enter the vessel. The apparatus enables venting of excess gas, thereby preventing over-pressurization of the vessel's structure and over-pressurization of the contents within the vessel. The apparatus regulates the flow of incoming gas, whereby gas is introduced at a consistent rate preventing disruption of the contents.
