The instant application is related to U.S. patent application Ser. Nos. 29/437,876, 29/437,886, and 29/437,888, all of which were filed on Nov. 21, 2012, all of which are fully incorporated herein by reference.
Embodiments of this invention relate to apparatus for aerating liquid, and more particularly, to an apparatus for aerating wine.
Aerating liquids, such as wine and the like, is a common method of improving the taste. Most wines are stored in a relatively oxygen free environment inside its bottle. Aerating wine is a process in which air is mixed into the wine, thereby increasing the exposure of the wine to oxygen and causing aeration. Aerating wine may open up the wine's aromas and cause the flavor profile to soften and mellow out a bit, thereby enhancing the overall flavor characteristics. As may be appreciated, aerating a wine too long may deteriorate the flavor profile, while not aerating long enough may not fully maximize the wine's flavor and bouquet. The amount of time necessary to aerate a wine depends on the age of the wine and the method used.
Embodiments of the present invention are illustrated by way of example, and not by way of limitation, in the figures of the accompanying drawings and in which like reference numerals refer to similar elements and in which:
Examples described below are for illustrative purposes only, and are in no way intended to limit embodiments of the invention. Thus, where examples may be described in detail, or where a list of examples may be provided, it should be understood that the examples are not to be construed as exhaustive, and do not limit embodiments of the invention to the examples described and/or illustrated.
By way of a general overview, one embodiment of the present disclosure is directed to an aerator. As may be appreciated, the aerator is particularly suited for aerating wine; however, the aerator should not be limited to wine unless specifically claimed as such as the aerator may be used to aerate any liquid. The aerator includes a pump assembly, a cannulated shaft, and a manifold assembly. As explained herein, the pump assembly is configured to provide a flow of air through the cannulated shaft to the manifold assembly which distributes the air to a plurality of radially arranged manifold nozzles. Each of the plurality of nozzles is configured to generate a plurality of bubbles having a radial velocity such that the air bubbles travel radially outward from the manifold assembly and vertically upwards generally towards the upper surface of the wine within the container (e.g., wine bottle and/or glass) substantially without touching the cannulated shaft or the sidewall(s) of the main body portion of the container (e.g., a standard 750 ml wine bottle having a bottle width/diameter of 60.3 mm or more). The bubbles transfer oxygen into the wine to increase the wine's exposure to oxygen and open up the wine's aromas and cause the flavor profile to soften and mellow out a bit, thereby enhancing the overall flavor characteristics.

With reference to
The pump 18 may be fluidly coupled to a shaft cavity 30 defined in the housing 24 by way of one or more air passages 32 to selectively provide a flow of air thereto. The air passage(s) 32 may be integrally formed as part of the housing 24 and/or may include any cannulated lumen (e.g., a flexible or rigid pipe and/or tube). The pump 22 may include any type of pump configured to supply the desired air flow rate and pressure such as, but not limited to, positive displacement pumps, impulse pumps, velocity pumps, and the like, for example, diaphragm pumps, rotary pumps, centrifugal pumps, etc. The pump 22 may be powered by an AC power source and/or a DC power source 20 such as, but not limited to, one or more batteries, AC plug, AC/DC converter, or the like. According to one embodiment, the pump assembly 12 may include at least one rechargeable battery which may be recharged using an onboard and/or remote AC/DC converter.
The shaft cavity 30 is configured to receive and retain a proximal end of the cannulated shaft 14 (not shown in
The shaft cavity 30 may optionally include one or more sealing members 34 (e.g., o-rings or the like). The sealing members 34 are configured to generally seal the cannulated shaft 14 to the shaft cavity 30 to minimize any air leakage therebetween. The shaft cavity 30 may also optionally include a taper (e.g., a conical taper) configured to form an interference connection with a corresponding taper (e.g., conical taper) of the proximal end of the cannulated shaft 14. Such an arrangement may aid in securing the cannulated shaft 14 to the pump assembly 12 while also allowing the cannulated shaft 14 to be easily removed from the pump assembly 12. Additionally (or alternatively), the shaft cavity 30 and/or the proximal end of the cannulated shaft 14 may include one or more locking features (such as a tap/slot/groove arrangement) configured to aid in securing the shaft cavity 30 and the proximal end of the cannulated shaft 14. For example, the proximal end of the cannulated shaft 14 may feature a protrusion or tab which extends outwardly from a portion of the cannulated shaft 14. The protrusion may be configured to be received in a slot/groove formed in the shaft cavity 30. The protrusion may be advanced into the slot within the shaft cavity 30 and then rotated to secured/lock the cannulated shaft 14 within the shaft cavity 30. As may be appreciated, other locking arrangements are possible for removably coupling the pump assembly 12 and the cannulated shaft 14. Additionally, it will be appreciated that the cannulated shaft 14 may be permanently secured and sealed to the pump assembly 12. As such, the shaft cavity 30 may optionally be eliminated.
The pump assembly 12 may optionally include circuitry 36. Circuitry 36 (which may include one or more printed circuit boards) may be configured to regulate power provided to the pump 18 by controlling the voltage of the power supplied to the pump 18 and/or the length of time that the pump 18 operates. For example, upon activation of the power switch 22, the circuitry 36 may provide power from the power source 20 to the pump 18 for a predetermined time. The predetermined amount of time may be selected to achieve an optimal enhancement of the overall flavor characteristics and aromas of the wine and is based on the flow rate of the pump 18, the bubble size, and the resulting amount of oxygen transferred. The circuitry 36 may therefore function as a timer in the sense that it allows the pump 18 to operate for a predetermined amount of time upon selecting the power switch 22. Predetermined time intervals may be, for example, thirty seconds, sixty seconds, and the like.
In a further optional embodiment, circuitry 36 may also be configured to recognize the length of the cannulated shaft 14 and/or the design of the manifold assembly 16 to change the timer length. For example, the cannulated shaft 14 and/or the manifold assembly 16 may include a bar code (or the like), a radio frequency identifier (RFID), or the like that may be in communication with (e.g., read by) the circuitry 36. The circuitry 36 may therefore select the appropriate timer length. Alternatively, the pump assembly 12 may include one or more inputs (such as, but not limited to, the power switch 22) which may be configured to provide a signal to the circuitry 36 to select the timer length. For example, the power switch 22 may be repeatedly depressed to scroll through a plurality of predetermined timer lengths stored in the circuitry 36. Optionally, a display (not shown for clarity) may be included to provide a visual indication of the selected timer length. Other configurations for selecting a timer length using the circuitry 36 are also possible.
The pump assembly 12 may optionally include one or more light sources 38 configured to provide a source of light to illuminate a portion of the pump assembly, the wine bottle, the wine glass, and/or the wine therein. The illumination allows the user to see the aeration at work and also provides an aesthetically pleasing appearance. The light source 38 may include any semiconductor light source such as, but not limited to, conventional high-brightness semiconductor light emitting diodes (LEDs), organic light emitting diodes (OLEDs), bi-color LEDs, tri-color LEDs, polymer light-emitting diodes (PLED), electro-luminescent strips (EL), etc. The LEDs may include, but are not limited to, packaged and non-packaged LEDs, chip-on-board LEDs, as well as surface mount LEDs. The LEDs may also include LEDs with phosphor or the like for converting energy emitted from the LED to a different wavelength of light. The LEDs may be simultaneously and/or independently controlled, for example, to adjust the overall color emitted from the light source 38 and/or compensate for changes in the output of the LEDs, for example, due to age, temperature, and the like as described herein.
The light source 38 is configured to receive power from the power source 20. For example, upon depressing the power switch 22, the circuitry 36 generates a DC signal at a desired current and voltage to power the light source 38, which may be transmitted across an electrical connector 40, such as a flexible wire, rigid wire, or the like. Optionally, the circuitry 36 may control various attributes of the light source 38, for example, the brightness (e.g., a dimmer circuitry) of the LEDs, color of the light emitted from the light source 38 (e.g., the light source 38 may include two or more LEDs configured to emit light having different wavelengths, wherein the circuitry 36 may adjust the relative brightness of the different LEDs in order to change the mixed color from the light source 38), adjust for changes in ambient lighting conditions (e.g., an ambient light sensor), adjust for temperature changes, adjust for changes in output due to lifetime changes, and the like.
The light source 38 may be coupled to the housing 24, for example, proximate to the shaft cavity 30 (e.g., proximate to the distal region 42 of the housing 24). As described herein, the distal region 42 of the pump assembly 12 may be inserted into the opening of a container, such as a wine bottle. The cross-section of the distal region 42, therefore, needs to fit within the wine bottle opening. In one embodiment, the shaft cavity 30 is offset relative to the longitudinal axis L of the housing 24 (e.g., the centerline of the pump assembly 12). Offsetting the shaft cavity 30 relative to the longitudinal axis L allows the light source 38 (e.g. a LED) to be aligned within the housing 24 to provide a downward illumination pattern while also minimizing the cross-sectional shape of the pump assembly 12 proximate to the distal region 42, thereby allowing the pump assembly to be inserted into a wine bottle opening.
The pump assembly 12 may optionally include one or more lenses, diffusers, or the like 44. The lens or diffuser 44 is configured to create a desired illumination pattern. According to one embodiment, the lens/diffuser 44 includes an optical lens/diffuser 44a which is secured to a distal end of the housing 24. Alternatively (or in addition), the lens/diffuser 44 may be integral to the housing 24. For example, the lens/diffuser 44b may include a portion of the housing 24 which defines the shaft cavity 30.
As discussed herein, the pump assembly 12 may be configured to be received in an opening of a container, such as a wine bottle. The pump assembly 12 may optionally include a tapered surface 46 configured to be received in the opening. The tapered surface 46 allows the pump assembly to be inserted into a variety of openings having different diameters. The tapered surface 46 may optionally include a flexible and/or resilient material. For example, the tapered surface 46 may include a rubber material. The tapered surface 46 also may include one or more flutes or air release grooves 48 (best seen in

The cannulated shaft 14 may be configured to be removably coupled to the manifold assembly 16, for example, using a tapered interference connection or the like. For example, at least a portion of the passageway/cavity 60 defined by the ferrule 54 includes a taper substantially corresponding to the taper of the distal end 62 of the cannulated shaft 14. The ferrule 54 may also form a clamp (e.g., a circular clamp) which may be crimped, swaged, or other deformed to secure the cannulated shaft 14 to the manifold assembly 16. The manifold assembly 16 may also be permanently coupled to the cannulated shaft 14.
As discussed herein, the manifold 52 is configured to receive a flow of air through the cannulated shaft 14 from the pump assembly 12 and distribute the air flow to a plurality of manifold apertures/nozzles 74 at a desired flow rate and pressure to generate air bubbles having a predetermined diameter, flow rate, pressure, and/or radial velocity to aerate the liquid (e.g., wine). The radial velocity of the air bubbles is selected to ensure that the air bubbles substantially do not adhere to the manifold assembly 16, the cannulated shaft 14 and/or the sidewalls of the main body portion of the container (e.g., wine bottle or glass). Some incidental contact of the air bubbles with the cannulated shaft 14, manifold assembly 16, and/or sidewalls of the main portion of the container may be considered within the scope of the present invention. While not a limitation unless specifically claimed as such, the phrase “substantially without touching the cannulated shaft or the sidewall(s) of the main body portion” means that 90% or more of the air bubbles do not touch the cannulated shaft or the sidewall(s) of the main body portion. As may be appreciated, the amount of oxygen transferred into the wine may be reduced if the air bubbles adhere to the manifold assembly 16, the cannulated shaft 14 and/or the sidewalls of the container. Additionally, air bubble adhered to the sidewalls of the main body portion of the container may create an aesthetically unpleasing appearance. Additionally, the size of the air bubbles should be selected to increase the oxygen transfer into the wine and may be selected based on the air flow rate, air pressure, and number of manifold apertures/nozzles.
Again, with reference to
The manifold 52 and/or the plenum 50 define a plurality of intake runners 76 and the manifold 52 and/or the ferrule 54 define the intake chamber 78. Turning now to
The manifold assembly 16 is configured to generate a plurality of air bubbles from the radially arranged manifold aperture/nozzles 74. In particular, the volume of the plurality of intake runners 76 and the intake chamber 78, as well as the position of the radially arranged manifold aperture/nozzles 74, is selected for a specific air flow rate and position of the bubbles as the bubbles exit the radially arranged manifold aperture/nozzles 74. Turning to
The radial velocity of the bubbles exiting the manifold apertures/nozzles 74 is selected such that the bubbles generally do not substantially adhere to the aerator 10 or the main body portion of the fluid container (e.g., wine bottle or wine glass). The radial velocity of the bubbles is therefore based on a number of factors including the air flow rate, the number of manifold apertures/nozzles 74, the manifold apertures/nozzle pressure, as well as the desired maximum radial travel distance. As may be appreciated, a bubble exiting the manifold apertures/nozzles 74 will travel radially outward and, due to the buoyancy of the air bubble, will also have a vertical velocity. After the bubble exits the manifold apertures/nozzles 74, the radial velocity will begin to decrease and the bubble will begin to travel substantially only vertically towards the surface of the liquid. The term “maximum radial travel distance” is therefore intended to refer to the maximum radial distance which a bubble travels after exiting the manifold apertures/nozzles 74.
Testing has found that for a manifold assembly 16 having a total volume of between 250 mm3 to 380 mm3 (e.g., 320 mm3), six manifold apertures/nozzles 74 having a half-circular cross-section having a radius between 0.0254 mm to 0.382 mm (e.g., 0.318 mm), a radial velocity of between 2.0 feet/second to 3.0 feet/second (e.g., 2.57 feet/second), a maximum radial travel distance of greater than 1 mm (e.g., between 1 mm to 20 mm, between 2 mm and 8 mm, between 2 mm and 5 mm, between 3 mm and 5 mm, between 1 mm and 3 mm, including all values and ranges therein), a manifold apertures/nozzle pressure of 0.1300 psi to 0.2100 psi (e.g., 0.1792 psi), and an overall flow rate of 240 centimeter3/minute to 360 centimeter3/minute (e.g., 300 centimeter3/minute) works over a wide range of wine bottles and wine glasses and provides enough oxygen transfer during a 30 second operation time (i.e., run time) to open up the wine's aromas and cause the flavor profile to soften and mellow out a bit, thereby enhancing the overall flavor characteristics.

The pump assembly 12 is configured such that at least a portion of the tapered surface 46 of the distal region 42 fits within (i.e., rests against and is supported by) the opening 92 of the wine bottle 90 in the neck portion 93. The air flutes 48 allow air 94 which is not absorbed into the wine 96 to exit through the opening 92 in the wine bottle 90 and past the pump assembly 12 seated therein. The cannulated shaft 14 is selected such that the manifold assembly 16 is arranged proximate to the bottom 98 of the main body portion 91 of the wine bottle 90. Streams of air bubbles 100 exit the plurality of manifold apertures/nozzles 74 having a radial velocity generally indicated by arrow Vr. The air bubbles 100 travel vertically towards transition portion 95 and the neck portion 93, and ultimately exit the liquid surface 102. It is possible that some of the air bubbles 100 may contact the transition portion 95 and/or the neck portion 93 of the wine bottle 90; however, this is acceptable since most of the oxygen transfer into the wine 94 will have already occurred. Additionally, any air bubbles adhered to the neck portion 93 and/or the transition portion 95 will typically be released after the first glass of wine is poured.
