A shell is provided having an actuator external thereto, a pressurized source of heavier-than-air inert gas is located within the shell and a regulator for reducing the pressure of the inert gas from a first pressure at the pressurized source of heavier-than-air inert gas to a second pressure at the open wine container.

Description
- The present application is a continuation-in-part of U.S. application Ser. Nos. 10/765,632 filed on Jan. 26, 2004 and 10/856,906 filed on Jun. 1, 2004.
- The present invention is directed to a device for the storage of an opened food container, such as an opened wine container or wine bottle. It has been recognized that food products such as wine and coffee, once opened and exposed to ambient air, oxidize thus changing their sought after characteristic taste. The present invention aids in the preservation of said food products and does so in a convenient compact package which can be completely self-contained or powered by an external power supply.
- Although the present invention will be described in terms of the preservation of wine, the invention can be extended to other food products such as coffee beans and ground coffee which similarly suffer ill effects when exposed to ambient (air) conditions.
- Virtually anyone who routinely drinks wine notices that if a bottle of wine is uncorked and not completely consumed, the wine contained within the bottle changes in physical and chemical characteristics making the wine much less enjoyable to consume as time passes. This is caused by oxidation, that is, the bonding of oxygen molecules to oxidizable compounds present within the wine. Oxidation of wine results in the production of brown compounds and browning of red pigments with loss of color. It further results in the production of aldehydes and desirable grape (primary), fermentation (secondary) and aging (tertiary) derived flavors. The production of new undesirable flavor compounds can mask the desirable flavor compounds.
- Such oxidizable compounds in wine include phenolics, alcohols and some flavor aldehyde compounds. Although all wines suffer from oxidation, because of the high concentration of phenolics extracted from grape skins during red wine production, red wine has a high reserve of oxidizable compounds and hence appears more sensitive to oxidative spoilage. Sulfur dioxide added to red wine loosely binds to red wine pigments decolorizing the pigment molecules and rendering a portion of the sulfur dioxide ineffective. Sulfur dioxide is also used to inhibit microbial growth and is thus a highly desirable additive for use in red wines.
- It has thus been recognized that it is highly desirable to limit or entirely prevent oxygen, such as that contained in ambient air, from contacting the surface of a food product, such as wine, in order to maintain the product's desirable flavor and other physical characteristics.
- There have been rather rudimentary attempts to inject an inert gas in the free space of an opened wine bottle in order to displace air contained therein. Such devices generally are in the form of a syringe-like product which enables the user to withdraw air from the bottle's free space or to inject a gas therein. However, such devices have proven to be ineffective in the flow of the inert gas to the free space above the wine and in removal of the ambient air to substantially reduce oxidation.
- It is thus an object of the present invention to provide a device, in a simple small and compact housing through the use of a single external control switch to enable one to preserve food products, such as wine and coffee, from the ill effects of oxidation.
- It is yet a further object of the present invention to provide a device such as that described above which can not only minimize oxidation but also control the food product's temperature, a desirable expedient in preserving food for an extended duration and to maintain the food product at its proper serving temperature.
- These and further objects can be more readily appreciated when considering the following disclosure and appended drawings.
- A device for storage of an opened wine container and for preserving wine contained within the opened wine container. The device comprises a shell, an actuator external to the shell, a pressurized source of heavier-than-air inert gas located within the shell and a regulator for reducing the pressure of the inert gas from a first pressure at the pressurized source of heavier-than-air inert gas to a second pressure at the opened wine container. A valve assembly is further included within the shell having a valve body biased to reside upon the open wine container and spaced from the open wine container when the heavier-than-air inert gas is fed through the valve assembly upon actuation of the actuator.

Device 10 is shown as a storage system in its preferred embodiment, capable of preserving a single, opened bottle of wine. As a preferred embodiment, storage can also be carried out while maintaining the opened bottle of wine at a predetermined and controlled temperature appropriate for enhancing preservation. As previously noted, wine preservation is maintained by the introduction of a gas or gas blend into the opened bottle of wine to displace air contained within the free space above liquid and within the bottle thus eliminating or substantially reducing the oxidation that typically renders wine less desirable for consumption allowing it to be drinkable for an extending period of time. As will be noted below, storage temperatures can be maintained through the use of a solid-state thermoelectric heating and cooling system. Ideally,shell 5 includingactuator 22 is presented to fully contain the open container and all of the operational components of the present invention. Shell 5 can be composed of either metal or plastic. - Turning to
FIG. 1 ,device 10 is shown as constitutingshell 5 having anupper assembly 12 andlower assembly 14 and see-throughwindow area 54 to enable one to view the food product container, such as a wine bottle label there through. In operation, the upper and lower assemblies can be separated enabling the user to place an opened bottle of wine or other food container inlower assembly 14. Once the bottle is in place, the assemblies are joined enabling one to begin the process of replacing air within the bottle with heavier-than-air inert gas such as argon to prevent or substantially reduce oxidation. Once the upper assembly has been installed into the lower assembly, a storage temperature can, optionally, be set for the desired type of wine or other food product. - Turning to
FIG. 4 , the overall gas cartridge and delivery system can best be visualized. In doing so,activation lever 22 is provided in conjunction withreplaceable gas cartridge 16 containing heavier-than-air inert gas. A threadedsafety barrel 18 is shown attachinggas cartridge 16 to gaspressure regulator assembly 20. Once the upper assembly is placed into lower assembly 12 (FIG. 1 ) valve body 114 (FIG. 2 ) resides atopbottle neck 100 and is displaced vertically to accommodate variations in bottle height. - Turning to
FIG. 2 ,valve body 114 can be caused to rest upon bottle neck 100 (FIG. 7 ) ofwine container 1 through gravity asshell 5 is intended to maintain a vertical orientation, at rest, as shown inFIG. 1 . Sealing engagement is enhanced by rubberized pad or o-ring 40. Alternatively,valve assembly 32, in providingrails 42 andhelical springs 52 can biasvalve body 104 againstneck region 100 ofbottle 1. In operation,valve support 34 constituting a portion ofvalve assembly 32 can surround and be guided byrails 42 which are oriented substantially as is the orientation ofopen wine container 1. In this orientation, thevalve assembly 32 guided byvalve support 34 can insert (FIG. 2 ) and disengage (FIG. 3 )valve body 114 smoothly and efficiently from the opening inneck region 100 in employing the present invention as discussed hereinafter. - In operation, by depressing
actuator 22,air valve 24 is depressed allowing high pressure gas stored inreplaceable gas cartridge 16 to flow topressure regulation chamber 92. The gas pressure regulator is composed ofcounter-balance spring 26,piston 28 andflow control needle 30. In combination, these elements reduce the high pressure in the range of 1,000 to 2,500 psi to a preferred operating pressure for approximately 15 to 20 psi. It is noted that low-pressure exits from theregulator section 92 viaflexible tube 64 andport 58. - Further, as the heavier-than-air inert gas passes through
flexible tube 64, it is fed withinvalve body 114 and throughorifice 90 contained therein. This introduces heavier-than-air inert gas withinneck 100. In that this gas, such as argon, is heavier than air, the oxygen-laden air is forced from the interior ofopen wine container 100, at a pathway being provided by the displacement ofvalve assembly 32 due to the increase in gas pressure within theneck 100 ofopen wine container 1. Thispathway 72 is depicted inFIG. 7 . - In order to introduce heavier-than-air inert gas well within
neck 100 and thus proximate meniscus 106 (FIG. 2 ),tube 104 can be provided as an extension to orifice 90. This introduces the inert gas well within theneck 100 noting that the inert gas, being heavier than air, first accumulates atmeniscus 106 and eventually displaces air which would otherwise be contained within the bottle as it moves upward within it. In employingtube 104, commingling of the inert gas and oxygen inneck 100 is significantly reduced. Also, by providingrestriction 70 withintube 104, the inert gas can be caused to gently flow withinneck 100 at a reduced volumetric flow rate again, reducing commingling of the inert gas and oxygen contained therein. - Once
lever 22 atopdevice 10 is released, gas pressure toregulation chamber 92 is interrupted and gas pressure tovalve assembly 32 is eliminated resulting invalve body 114 either through gravity or spring bias receding againstneck 100 ofopen wine container 1 as shown inFIG. 2 . This substantially sealsneck 100, substantially preventing gas from escaping thus preserving the bottle contents beneath an atmosphere of heavier-than-air inert gas. - As noted previous, as a preferred embodiment, the present invention employs hollow
tubular member 104 for directing heavier-than-air inert gas within the confines of the open wine container. In doing so, the heavier-than-air inert gas is directed closer to themeniscus level 106 of the wine and away fromvalve body 114 thus providing for decreased turbulence and more effective venting of oxygen contained within the open space above the liquid level. When dealing with traditional 750 ml wine bottles,hollow tubular member 104 should ideally be sized to extend within the open wine bottle a distance of approximately 4 inches which would typify the liquid level of wine once a single glass has been decanted. It is anticipated that the present invention would only be used in the event that the wine bottle was open, and, typically, one would not open and store wine in a bottle unless at least a single glass was decanted. Hollowtubular member 104 could, however, extend along its longitudinal axis to the full anticipated height of a typical 750 ml wine bottle if desired. Although not shown,hollow tubular member 104 could be characterized as having a series of perforations extending substantially along its longitudinal axis as was described in parent U.S. application Ser. No. 10/856,906, the disclosure of which is incorporated by reference herein. - As further noted previously,
shell 5 of the present invention further employs, as a preferred embodiment, a cooling system to maintain the storage temperature of the wine or other food product. Reference is made toFIGS. 2, 5 and 6 showing thermoelectric cooler 44 creating a temperature differential between two separate forced air currents. The two currents are thermally separate as “cold air” and “hot air” circuits.Wine bottle 1 is placed in the closed loop cold air circuit.Thermoelectric cooler 44 extracts heat from the cold air circuit and transfers it to the hot air circuit where it is exhausted to the atmosphere. - In operation, the hot side circuit draws ambient air through
entrance port 78. The air is then drawn over the hotside heat sink 48 where it becomes heated due to convective heat transfer from the hot heat sink to ambient air. The air is then drawn throughhot side fan 80 and exhausted through hotside exhaust port 82. Air is drawn through cold-air return port 84 and is then drawn over cold-side heat sink 46 wherein it is cooled. The cold air subsequently passes through cold-air fan 86 and is exhausted into the bottle compartment through cold-air exhaust port 88. The cold air cools the bottle compartment noting that a thermistor in the cold air circuit is coupled with a potentiometer mounted on printed circuit board 50 to control the power of thermal electric cooler 44 which in turn determines the temperature in the cold air circuit. This provides thermostatic control of the wine bottle temperature. A knob attached topotentiometer 52 allows for adjustment of the storage temperature. - As noted previously, although the present invention has been described in terms of preserving wine contained within a wine bottle as a preferred embodiment, this invention could also be employed for preserving other food products which are sensitive to the oxidation effects of ambient air. For example, coffee beans and ground coffee would benefit greatly through the use of the present invention.
