Closure device and method for preserving oxidizable products

A closure device for a container, comprising:

• a body defining a chamber for storing one or more primary gases and at least one absorbent material;
• a fastening member circumferentially extended around an outer surface of said body, wherein said fastening member is configured to create an airtight seal for an open end of said container upon insertion of said closure device through said open end;
• a blister positioned at one end of said body;
• a hollow shaft operably connected to said blister and disposed within said body, wherein said hollow shaft contains at least one secondary gas;
• and
• a seal member disposed at a bottom of said body,
• wherein, upon actuation of said blister, said hollow shaft penetrates said seal member, thereby simultaneously releasing said one or more primary gases from said chamber and said at least one secondary gas from said hollow shaft into said container to form a protective barrier against oxidation within said container, and exposing said at least one absorbent material to a headspace of said container for absorbing oxygen,
• whereby said closure device preserves products disposed within said container through a combined action of inert gas blanketing and oxygen absorption while maintaining said airtight seal.
