Closure device and method for preserving oxidizable products
View Patent ↗A closure device for a container to provide a combined protection of inert gas and oxygen scavenger methods. The closure device comprises a body, a fastening member, one or more plurality of protrusions, a blister, a hollow shaft, and a seal member. The closure device is removably coupled to an open end of the container through a fastening assembly. The fastening assembly includes at least one of friction fit, a snap fit, a screw fit, or any of a variety of fastening mechanisms. The closure device provides a combined protection of inert gas and oxygen scavenger methods. This is beneficial because it prevents nutritional and organoleptic degradation processes of wine through oxidation while aids to preserve the fruitier and fresher aromas and flavors of the wine. The closure device is designed to fit snugly over the neck of the bottle and create an airtight seal.
1 . 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.
2 . The closure device of claim 1 , wherein said at least one absorbent material is a de-oxygenation agent or an oxygen scavenging agent.
3 . The closure device of claim 1 , wherein said closure device is removably coupled to said open end of said container through a fastening assembly, wherein said fastening assembly includes at least one of a friction fit, a snap fit, a rotatable fit or screw fit, or any of a variety of fastening mechanisms.
4 . The closure device of claim 1 , wherein said closure device is made of a material includes at least one of plastic, silicone rubber, metal, natural cork, and synthetic cork.
5 . The closure device of claim 1 , wherein said closure device is made of a plastic material, which includes at least one of polyethylene terephthalate (PET), high-density polyethylene (HDPE), thermoplastic elastomer (TPE), polypropylene (PP), ethylene vinyl alcohol copolymer (EVOH), and polyamide (PA).
6 . The closure device of claim 1 , wherein said fastening member is made of a material that includes at least one of plastic, silicone rubber, and any flexible polymers.
7 . The closure device of claim 1 , wherein said fastening member comprises plurality of protrusions extended outward radially from a surface of said fastening member, wherein said plurality of protrusions is engaged with an interior surface of said container to ensure said airtight seal for said open end of said container.
8 . The closure device of claim 1 , wherein said hollow shaft defining a channel for storing said at least one secondary gas.
9 . The closure device of claim 1 , wherein said one or more primary gases and said at least one secondary gas are inert gases include at least one or a mixture of gases that are heavier than oxygen, which include at least one of argon gas, krypton gas, xenon gas, radon gas and carbon dioxide gas, wherein most preferably at least one primary gas comprise argon gas and said at least one secondary gas comprise carbon dioxide.
10 . The closure device of claim 1 , wherein said at least one secondary gas comprise argon gas.
11 . The closure device of claim 1 , wherein said at least one absorbent material includes at least one of metal-based substances and non-ferrous absorbent material, wherein said non-ferrous absorbent material absorbs oxygen within from said container to release said at least one secondary inert gas which is carbon dioxide to form said protective barrier.
12 . The closure device of claim 1 , wherein said closure device comprises an indicator unit for indication of the presence of oxygen in said container.
13 . The closure device of claim 12 , wherein said indicator unit includes at least one of a display and an oxygen indicator dye to measure oxygen levels present within said headspace of said container.
14 . A closure device for a container, comprising:
a body defining a channel for storing one or more inert gases and at least one oxygen absorbing agent;
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 with an indicator unit fixedly disposed on said body;
a hollow shaft operably connected to said blister and positioned within said body, wherein said hollow shaft is configured to contain at least one inert gas; and
a seal member disposed at a bottom of said body,
wherein actuation of said blister causes said hollow shaft to puncture said seal member, thereby releasing said one or more inert gases from said channel and said at least one inert gas from said hollow shaft into said container to establish an inert gas barrier and expose said oxygen absorbing agent to a headspace of said container,
whereby oxidation of contents within said container is inhibited through coordinated inert gas displacement and oxygen absorption.
15 . The closure device of claim 14 , wherein said body, said blister, and said hollow shaft are made of a material that includes at least one of plastic, silicone rubber, metal, natural cork, and synthetic cork.
16 . The closure device of claim 14 , wherein said fastening member is made of a material that includes at least one of plastic, silicone rubber, and any flexible polymers.
17 . The closure device of claim 14 , wherein said fastening member comprises plurality of protrusions extended outward radially from a surface of said fastening member, wherein said plurality of protrusions is engaged with an interior surface of said container to ensure said airtight seal for said open end of said container.
