Definitions

• the present invention generally relates to aeration of wine. More particularly, the present invention relates to devices that aerates wine in a wine glass, bottle or other container at an accelerated rate through the expansion and control of aeration bubbles.
• Decanting accelerates the breathing process, which increases the wine's aromas from natural fruit and oak by allowing a few volatile substances to evaporate. Decanting also softens the taste of tannins that cause harshness and astringency in young wines. In older red wines, the tannin reactions have proceeded long enough to reduce astringency. As a result, the taste is not as harsh when the wine is drunk straight out of the bottle. In comparison to reds, white wines have little tannin and are not aged in bottles for very long before serving. Thus, they have very little opportunity to develop bottle aromas that need evaporation. Instead, their natural fruit aromas more specifically define their taste. There are however, a number of white wines that can benefit from decanting, or specifically aeration.
• the inventors have experimented with such techniques and have found that this is no more efficient than decanting. In other words, it can take up to 20 minutes by very slowly putting bubbles into the wine and creating a slight surface agitation such that the wine will not froth out of the bottle.

• the ⁇ 04 patent suffers from all of the same deficiencies as described in the Vassallo and Wettern patents. The deficiency is the air flow out of the distal tip 18 would have to be extremely low such that a bubble and froth wasn't created, which would cause wine to overflow the outside of the wine bottle and pour, for example, down onto a countertop.

As one can see, the volume of gas flow injected at or near the bottom of the wine bottle 18 is extremely high producing a huge bubble formation and froth 54, which is temporarily collected in the expansion chamber 12. This whole process is incredibly quick.
• the inventors have demonstrated that all it takes to partially reduce the tannins and remove astringent properties of a wine 52 is just a few seconds of high surface area bubbling like this. This is in stark contrast with all of the other prior art where the bubble formation is so low it will not overflow the container.
• the flow rates of the present invention tend to be at least an order or magnitude greater than the prior art.
• the inventors have done a set of very interesting experiments using the configuration shown in FIG. 4. These experiments have been performed by pinching down the flexible extension tube 31 , wherein, no expansion chamber 12 was used. In other words, the inventors wanted to see if a very small amount of air bubble formation could be produced, such that the wine would not overflow the top of the wine bottle. This was found to be the case.
• the bubble formation 54 can be reduced to the point where the bubbles do not overflow the top of the wine bottle 18.
• experimentation has shown that one must do this for at least several minutes to properly aerate the wine and as much as 10 to 20 minutes, or in some cases hours. This makes this pinching technique hardly any more efficient than the old method of decanting.

• FIGURE 1 1 illustrates a wine glass 62.
• connoisseurs of red wine prefer relatively large wine glasses, such as the Libbey 8414 Citation 12 ounce glass.
• the reason that red wine glasses have evolved to have very large surface area has to do with improving the taste of the wine by swirling it or letting it sit for extremely long periods of time, thereby facilitating oxygen exchange.
• the wine glass 62 can be of any shape or dimension, even one small in diameter and/or like a tall champagne flute. This is because the present invention can provide aeration to the wine in any shape of wine glass.
• Aeration element 42 has been previously described and can have various densities providing varying diameters and velocities of the air bubble 54.
• Element 64 is a quick disconnect allowing one to disconnect the gas conduit 30 from the gas conduit extension 31 . Having this quick disconnect facilitates a number of things. For example, by disconnecting the gas conduit 30 from the gas conduit extension, one can then place the subassembly of the gas conduit 30 with aeration element 42 into a dishwasher for cleaning. This also facilitates changing out various aeration elements for different types of wine. For example, having a more aggressive aeration for a heavy body wine like Burgundy would be in marked contrast to a lesser body wine like a Zinfandel, where finer bubbles may be optimal.
• FIGURE 12 illustrates that the previous gas conduit 30 can be made into a telescoping gas conduit 66 (30). This is useful, for example, a shorter bottle of wine (also called a split) and a taller or regular bottle of wine or even a magnum bottle of wine, which is much taller.
• the expansion chamber 12 has an integral rubber seal 44. By its own weight, this causes a seal between the top lip of the wine bottle and the chamber 12. This is important so that the wine bottles do not leak out and overflow down the sides of the wine bottle. Instead, this way the bubbles form inside the wine bottle and then are transferred into the expansion chamber 12 without leakage.

• the wine bottle 18 is more accurately drawn, in that, it includes a punt 70. Almost all wine bottles have a punt 70. This not only increases the strength of the wine bottle, but also leaves an area on either side of the punt (think of this as a diameter) where sediments may collect.

One could then adjust the timer knob 72 to the desired time setting. Obviously, this may take some experimentation on the part of the consumer. This would allow the consumer or restaurant server to start up the air pump 36 and then walk away, as it will automatically shut off.

• FIGURE 14F illustrates yet another embodiment where there is an on/off switch 40, but now there is a separate timer switch 72 and a separate flow rate switch 49. Now the timer and flow rate can easily be selected and changed. For instance, one could combine the teachings of FIG. 14C and FIG. 14D. To do this, one would remove the on/off switch 40 from FIG. 14C and replace it with the digital display 45 and the on/off switch 40 and the mode switch 41 from FIG. 14D. However, referring back to FIG. 14C, one would keep the rheostatically controlled flow rate switch 74. In the inventors' experience, when one is observing bubble flow, one has to very quickly make both coarse and fine flow rate adjustments in order to hold the bubbles at an equilibrium height.

• the inventor's believe that it may be beneficial to create a turbulent flow as compared to a laminar flow for aerating the wine with bubbles. Therefore, it is desired that the Reynold's number is increased to help the exchange of oxygen with the wine.
• Laminar flow is the orderly flow of tiny particles (or, in the case of this invention, bubbles) along a thin line, whereas turbulent flow is more chaotic and results in the particles (bubbles) being dispersed throughout a larger area.

• Increasing the diameter in which the bubbles are added to the container (whether it be the wine glass or the wine bottle) will inherently reduce the thickness of the boundary layer as it will ensure a greater diameter of the column of fluid is seeded with the gas bubbles.
• Adding bubbles in a wider array and at various positions will also increase the turbulence in the system as the bubbles interact with the wine fluid and each other and aerate the wine in a more expedient manner.

• the inventors are hereby teaching that all of the elements that are in contact with wine, including any tubing, gas conduits and in particular, the aeration elements must be of FDA food grade materials, including materials that are resistant to solvents (such as alcohol), non-toxic and generally biocompatible. Furthermore, these materials will not break down over time while releasing binders or solvents or other chemicals into the wine. This not only preserves the taste of the wine, but also ensures consumer safety.
• the term "food grade” includes all of the aforementioned elements.
• FIGURE 38 is very similar to FIG. 37 except that the retention chamber 12 has a rounded, enlarged or bulbous shape. As it turns out, through numerous experiments by the inventors, that this creates a maximum diameter 124 wherein, the bubble field 54' will tend to stabilize and rise no higher. As can be seen in the figure the retention chamber 12 of FIG. 48 also incorporates a pour spout 90.
• FIGURE 39 it is shown, a pump element 36 with a control knob 74, 40 which not only turns the pump on and off, but also adjusts its flow rate.
• This is a two- piece assembly, in that the aeration element 42 is designed to slip down through the middle of the retention chamber 12 of FIG. 38. Having the retention chamber 12 be a separate piece from the pump structure 36 and its associated aeration element 42 is a very important novel feature. For example, this allows easy cleaning in a dishwasher of the retention chamber 12.

• FIG. 39A illustrates the draft angle theta ( ⁇ ) 126 has been reduced thereby providing a tighter fit between seal 44 and the inside diameter 22 of the wine bottle neck 20.
• Angle theta ( ⁇ ) 126 has to be greater than zero degrees so that not too tight a fit between the seal element 44 and the inside diameter 22 of the bottle neck 20 is formed or else that would make it very difficult to remove the retention chamber 12 after the wine (or other liquor) was bubbled and ready for consumption.

• the overall height 128 of the seal area 44 is also very important.
• This height 128 can vary from anywhere from a 1 /4 of an inch to 3 inches. It is important that the retention chamber 12 properly engage the inside diameter and surface 22 of the wine bottle neck 20, such that it will not tilt or tip over. Attention is now drawn to the inside diameter 130 of the retention chamber 12 as it is inserted into the bottle 18. Referring once again to FIG. 39, one can see that the aeration element 42 is at the distal end of air passage 30.
• the overall length of the neck 128 is not nearly as important as its inside diameter 130.
• the inventors created a 3D model wherein, the inside diameter was exactly 0.45 inches. Pour experiments indicated a very low, interrupted and generally unacceptable flow rate. Cutting the length 128 in half had very little effect on this pouring flow rate. However, increasing the diameter 130 to 0.50 inches, produced a much smoother and more laminar flow rate, which was much more pleasing. In summary, the diameter 130 may be greater than 0.45 inches.
• FIGURE 39B is taken from section 39B-39B from FIG. 39 and shows that the retention element can have a trapezoidal-like or frustoconical shape instead of cylindrical, as previously illustrated in FIG. 39.

• FIGURE 39C is taken generally from section 39C-39C from FIG. 39 and shows that indeed the aeration element 42 may be cylindrical. However, in this case, a frustoconical plastic piece 136 has been added to facilitate easy removal through the aperture 130 of the retention chamber 12. Similarly, the diameter of the aeration element 132' must be less than the opening diameter 130 of the retention element 12 such that the entire assembly shown in FIG. 39 can be slipped down inside of the wine bottle and also easily removed.
• FIGURE 39D is a sectional view taken from section 39D-39D from FIG. 39, showing that in this embodiment, the diameter of aeration element 42 is exactly the same as the diameter of the air tube assembly 30. This eliminates any ledge 138, which also facilitates easy removal through the aperture 130 of the retention chamber 12 as previously described in FIG. 38. Again, the diameter of the aeration element 132" must be less than the opening diameter 130 of the retention element 12 such that the entire assembly shown in FIG. 39 can be slipped down inside of the wine bottle and also easily removed. It will be appreciated and understood that the aeration elements shown in FIGS. 39B, 39C and 39D are enlarged in comparison to FIG. 39A.
• FIGURE 39E is taken generally from section 39E-39E from FIG. 39. This illustrates how the air passage tube 30 can be quickly inserted into the bottom of the pump housing 36 and sealed by O-ring 146 into hole 148.
• this tube 30 would be of a stainless steel and the aeration element would be of a porous, sintered, stainless steel. As previously mentioned, this allows one to place the aeration element 42 along with the stainless steel tube 30 in a residential or commercial dishwasher or even into boiling water or the like.
• O-ring 146 could take on many other shapes as sizes as it is not to be limited to only an O-ring configuration.

• the inventors have determined that the minimum diameter 124 of the retention chamber 12 is 0.75 inches. At the minimum diameter of 0.75 inches, the retention chamber maximum diameter 12 is quite small, meaning that the pump flow rate would have to be undesirably lowered to a very low rate. This requires a relatively long bubbling time to properly aerate the wine or spirits.
• a practical upper limit to the diameter 124 of the retention chamber 12 is 5 inches. At 5 inches, a very high pump flow rate can be used.
• the mass of the retention chamber 12 becomes sufficiently large to create a potential toppling or overturning problem concerning with the bottle 18. It also creates aesthetic concerns. Obviously, one could go to a retention chamber diameter 124 of even 10 inches, but this would be veryly large to have sit on top of a wine bottle 18. It will be understood that the diameter of the retention chamber, can vary in 0.25 inch increments all the way starting from 0.75 inches all the way to 5 inches.
• the material of the expansion chamber 12 be clear, such as a glass, an acrylic or other clear plastic or glass material. Having this material clear, allows one to readily observe the bubble expansion field 54' and if needed, adjust the pump flow rate accordingly. In addition, there is an aesthetically pleasing element by watching the bubbles form in the retention chamber 12. In one embodiment, a red or other color LED light 142 would shine down when the pump 36 was activated thereby, highlighting the bubble field 54'.
• FIGURE 40B shows the retention chambers previously illustrated in FIGS. 38 through 40A except that an indicator line 144 has been added.
• This indicator line 144 could be etched on the surface, applied with paint, applied with a sticker, or formed in the molding process, wherein, the top half of the retention chamber is joined at the bottom half of the retention chamber 12.
• one adjusts the flow rate of the pump until it reaches this ideal maximum diameter where the height of the bubble field 54' reaches a static (steady-state) position.
• FIGURE 41 utilizes the same type of pump 36 as previously illustrated in FIG. 39 except in this case, the straight tube 30 and aerator 42, previously described in FIG. 39, has been removed (simply pulled out of recess 148 in FIG. 39E) and replaced with the new fill tube 30', including the two bend radii 152, which allows the aeration element 42 to be placed parallel in the bottom of a wine glass 62.
• this takes advantage of the Reynolds number, in that, the bubbles 52' that are formed are being formed over a much wider dispersal area, thereby, more efficiently causing oxygenation of more of the wine or spirits. So one can refer to FIG. 41 A to see the bubble formation 52'.
• FIG. 41 A see the bubble formation 52'.
• the physics have not changed.
• the wine glass 62 forms its own retention chamber 12 similar to that previously described in FIGS. 38 through 40B. As one can see, when the bubble field 54' reaches the point of maximum diameter of the wine glass 62, it will reach a point where it inherently wants to become stable (steady-state) or reach a static height.
• the pump 36 flow rate can be adjusted such that the static level of the wine bubbles 52 can be easily achieved and maintained.
• the bend radius 152 has to be tight enough, such that the aeration element 42 will fit into a wide variety of wine glasses, including ones that have a relatively narrow neck.
• the aeration element 42 will fit into a wide variety of wine glasses, including ones that have a relatively narrow neck.
• bubble field 54' would tend to rise very rapidly.
• the person that is aerating their glass of wine 62 is holding the pump assembly 36 in their hand and they're watching in real time as the bubble field 54' is being formed. Accordingly, if the bubble field 54' is rising too rapidly, the solution is very simple. One only needs to raise up the entire pump assembly 36 and remove the aeration element 42 temporarily from wine 52, such that the bubble formation 54' stops.
• the centerline 154, of air tube 30' will bisect the distance 156, which is the distance between the end of the gas tube radius 152 and the distal tip aeration element 42.
• FIGURE 42 illustrates that the switch 40 can be disposed on top of the pump housing 36 and that the air flow rate adjustment knob 74 can be disposed circumferentially around the top.
• FIGURE 43 is very similar to FIG. 42, except that in this case, the switch 40 is a push button switch disposed on the side. It will be appreciated that these can be any types of switches or adjustment knobs, including digital controls as previously described. It will also be appreciated that it is not necessary in the present invention, that the pump flow rate be infinitely adjustable through an adjustment rheostat 74.
• the pump can come with predetermined flow rates, such as a first and a second flow rate, one being at low speed and the other being at high speed. It will also be appreciated that the pump flow rate could be adjusted through a detent-type switch having, for example, five even pin preset flow rates.

• the pump assembly 36 fits tightly into the top opening of retention chamber 12.
• FIGURE 46 is very similar to FIG. 44 and FIGURE 47 is very similar to FIG. 45.
• the difference is that the aeration element 68 is permanently attached into the bottom of the retention chamber 12 and the aeration element 42 is approximately the same diameter as the gas tube 30. This allows the gas tube 30 and aeration element 42 of FIG. 46, to be inserted down through the aeration element 68 and the pump assembly 36 will be seated into the opening of the retention chamber 12 holding it in a vertical, upright and stable position.
• FIGURE 48 describes a variation of the retention chamber 12 wherein there is an essential aperture 162 designed to receive aeration element and its associated gas tube 30, as shown in FIGURE 49.

In some cases, having this additional spacing is highly desirable so that one does not undesirably have the aeration element 42 undesirably stir up sediments 71 in the wine bottle, which are generally located towards the bottom of the pump 70.
• FIGURES 51 and 52 illustrate that the stop 164, in this case, having an adjustable cross-tip screw 165, can be adjusted such that the aeration elements 42 is disposed at an even greater distance above punt 70.

• FIGURE 55 illustrates the wine bottle 18 and the retention chamber 12 of FIG. 53 mated with the pump assembly 36 of FIG. 54 showing the engagement of element 168 with the counter-bore 170'. Please note that there is an air gap 140 that is formed between the pump housing 36 and the inside diameter of the retention chamber 12 thereby, allowing air to freely escape during bubble formation.
• FIGURE 56 is very similar to FIG. 53, except that the counter-bore 170' has been raised up to the midline of the retention chamber maximum diameter 12 as shown. There are a number of air passage holes 160 that allow air to escape as bubbles are being formed. Importantly, this plurality of small air bubbles 160 also act as a bubble breaking filtration element. As previously described in FIGS. 54 and 55, Element 168 is snuggly fit and engages the counter-bore 170' thereby, holding the pump assembly 36 in a stable upright position during operation.

It will be noted in FIG. 62 that a maximum diameter 124 is still created that acts as a bubble-stabilizing element. In FIG. 63, this maximum diameter area 124' is dispersed over a wider area, indicating that the static level of bubble height can be achieved anywhere within that region.

• FIGURE 65 indicates that the retention chamber 12 can mimic the shape of a wine glass, including a pour spout area 90. Referring once again to FIG. 65, one can see that the opening at the top is the largest opening. This facilitates making one piece from a simple two-part mold because all of the draft surfaces are such that the entire retention chamber 12 can easily be removed from the mold.
• the retention chamber 12 of FIG. 65 offers a number of other advantages as well. For one, it is very easy to quickly clean and dry with a hand towel and they can also be stacked upside down in trays, for example, in a restaurant.

• FIGURE 69 illustrates a dishwasher basket 176, which is generally of stainless steel or the like and has a mesh or open weave type of structure. This allows for the holding of any number of air passage tube 30 and distal aeration element 42 of the present invention. For example, in a restaurant operation, one may need to wash 20, 30 or even more of these at the same time.
• FIGURE 70 illustrates a different method of air control wherein, the pump speed is held constant.
• the air screw 178 can be turned to pinch off the air flow in portion 150 thereby allowing air flow control.
• a disadvantage of having the set screw 178 screwed all the way in is that this would almost completely block off the air flow from the pump.
• a negative of this is that back pressure is created against the pump, which also increases its temperature while draining more electrical energy.
• FIGURE 71 A superior embodiment is shown in FIGURE 71 wherein, the pump speed is still held constant and an air bleeder screw 180 is employed. As the screw 180 is unscrewed and the distal end of the screw is pulled out, this allows air to escape from passage 150 and be bled off, which thereby reduces the amount of air to the aerator element 42 (not shown).
• An advantage of the air bleeder structure shown in FIG. 71 is that air can be diverted from the distal aeration element 42 without placing back pressure on the pump, which could cause damage to the pump or at the very least, increase electrical current flow to the pump.

• FIG. 72 Having the heating element 182 in series with the air tube 30, as illustrated in FIG. 72, is more efficient. Having the heater element 182' disposed where cool air comes in, as described in FIG. 73, is actually inefficient, as that heated air then must flow past the battery 184, past the circuit board 186 and then past the motor 188 thereby, heating all of them up slightly before it is drawn into the inlet of the pump assembly 190 and then discharged through the gas tube 30.
