The present invention relates to apparatus for aerating liquid and, more particularly, to a device that filters and aerates a liquid such as wine as the liquid is poured into a wine glass or other vessel.
The taste of many wines can be improved by aerating the wine or allowing the wine to “breathe”. Simply uncorking a wine bottle and allowing the bottle to sit for a period of time is an ineffective method of aerating wine because the surface area of the wine exposed to the air is very small.
Decanting is often used to aerate and remove sediment from wine. Decanting includes the steps of setting the wine bottle upright for a period of time to allow the sediment to settle, opening the bottle and carefully pouring the wine from the bottle into a wide mouthed vessel or decanter until the sediment begins to appear in the neck of the bottle, and allowing the wine to sit in the decanter for a period of time to aerate. Decanting is suitable for home use where the wine can be selected beforehand.
The time required to aerate wine by decanting may not be available as, for example, when wine is served at restaurants. Known mechanical devices that accelerate the aeration of wine include pumps that pump air directly into the wine, and a motorized apparatus that pours the wine back and forth between two vessels. U.S. Pat. No. 7,299,743 to Moore discloses a decanter with a mesh filter that sits across the mouth of the decanter, a depression in the filter, a sphere that sits in the depression, and a valve at the bottom of the decanter for dispensing the wine. In Moore, wine is poured over the sphere to aerate the wine and through the filter to filter sediment.
Other known aerators include channeled spheres that are sized to fit across the diverging or flaring mouth of a carafe or decanter. Another known aerator for use with a decanter includes a glass funnel, and a metal spiral that fits inside the funnel and has a ball at the lower end. The Sharper Image® currently sells an aerator that sits on top of a wine glass. Vinturi, Inc. currently sells aerators for pouring wine into a wine glass. The Sharper Image® and Vinturi, Inc. aerators appear to flow wine through a tube with side holes.
An aerator has a rounded aerating portion, a suspension system having a plurality of diverging rods that project upwardly from the aerating portion and bars that connect the rods opposite the aerating portion, and a filter that sits on the rods above the aerating portion. The aerating portion is smaller than the mouth of a vessel such as a wine glass. The rods rest on the mouth of the vessel with the aerating portion at or below the mouth. Wine is poured from a bottle through the filter, over the aerating portion and into the vessel.
Details of this invention are described in connection with the accompanying drawings that bear similar reference numerals in which:

Referring now to
The suspension system 15 is connected to the aerating portion 14, and is sized and shaped to rest on the mouth 19 and suspend the aerating portion 14 in spaced relationship to the vessel 18 substantially below the mouth 19. The suspension system 15 is open, and allows liquid to flow over and around the aerating portion 14. The suspension system 15 includes a plurality of spaced rods 21 that project in different directions from the aerating portion 14. The suspension system 15 shown has three equally spaced, straight, cylindrical rods 21 that project from the aerating portion 14 in diverging directions, forming an inverted, triangular pyramid shape.
At least two rods 21 are needed to suspend the aerating portion 14 in the mouth 19 of the vessel 18, and more than three rods 21 can be used. If only two rods 21 are used, the rods 21 could project in opposite directions, but the two rods 21 would preferably project at a diverging angle to provide stability and to provide for support of the filter 16, described hereinafter. The rods 21 shown are straight and cylindrical. Alternatively, the rods 21 can be curved, can have other cross sectional shapes, and can have nonuniform cross sectional size, such as a taper. In the illustrated embodiment, the suspension system 15 includes a plurality of bars 22, with a bar 22 connecting the ends of each pair of rods 21 opposite the aerating portion 14.
The aerating portion 14 and suspension system 15 shown are made of glass. Alternatively, the aerating portion 14 and suspension system 15 could be made of plastic or metal, such as stainless steel. Preferably, the material used to make the aerating portion 14 and suspension system 15 is stain resistant.
The filter 16 includes a rim 24, a mesh portion 25 and a means 26 for releasably securing the filter 16 to the suspension system 15. The filter 16 is sized and shaped to be positioned on the suspension system 15 above the aerating portion 14. The rim 24 shown is circular. The mesh portion 25 connects across and around the rim 24, and is convex downwardly, extending downwardly and inwardly. The means 26 for releasably securing the filter 16 shown includes spring clips 28 that attach to the rim 24 and partially encircles each rod 21. Other fastening devices can be used for the means 26 for releasably securing the filter 16. The filter 16 is preferably made of stainless steel, but can be made of other materials.
The aerator 10 is placed onto the mouth 19 of a vessel 18, such as a wine glass. Wine from a bottle is poured onto the filter 16. The wine flows through the filter 16 and onto the aerating portion 14, while sediment is retained by the filter 16. The wine flows over the aerating portion 14 in a thin sheet with the aerating portion 14 exposing a large surface area of wine to the surrounding air and thereby aerating the wine. The aerator 10 can be used with vessels 18 other than wine glasses, such as decanters, carafes and other drinking glass types, and can be used to aerate liquids other than wine. The aerator 10 filters and aerates wine in 10 20 to 30 seconds, compared to the 20 to 30 minutes, or longer, required to filter and aerate wine with a conventional decanting method.
Although the present invention has been described with a certain degree of particularity, it is understood that the present disclosure has been made by way of example and that changes in details of structure may be made without departing from the spirit thereof.
