Description

CROSS REFERENCE TO RELATED APPLICATION

[0001] The present application claims the filing benefit of U.S. provisional application, Ser. No. 61/710,245, filed Oct. 5, 2012, which is hereby incorporated herein by reference in its entirety.

FIELD OF THE INVENTION

[0002] The present invention relates generally to coffee and filters for automatic drip coffee makers.

BACKGROUND OF THE INVENTION

[0003] Typical coffee makers, such as the automatic drip type of coffee maker, require a filter that is placed in the coffee maker, and then a desired amount of coffee grounds (such as a selected or desired number of "scoops" of coffee grounds) is placed in the filter. The selected amount of coffee grounds that is added determines the strength of the brewed coffee and the amount of coffee that is to brewed. Such scooping of coffee grounds is inconsistent in providing the same amount of coffee grounds for each pot of coffee and thus does not consistently result in the desired coffee. Also, such scooping often leads to spillage of some of the grounds on the counter or support surface by the coffee maker.

SUMMARY OF THE INVENTION

[0004] The present invention provides a coffee filter unit that has a predetermined amount of coffee grounds contained in a filter pouch. The amount of coffee grounds and size of the filter pouch and shape of the filter pouch may be selected so that the coffee filter unit may readily fit into a typical sized coffee maker reservoir, so that when hot water flows into the reservoir, it passes through the coffee filter unit to brew coffee. If a user of the brewing device wants a stronger brew of coffee, the user may add a second or third coffee filter unit by simply adding another unit at or on top of the first unit. The coffee filter units may all contain generally about the same amount of coffee grounds therein, or different sized coffee filter units may be provided with some having more or less coffee grounds than others.

[0005] Thus, the present invention provides a coffee filter unit and method of brewing coffee that allows for a user to use individually formed coffee filter units to brew coffee to a desired strength. The present invention provides such a method without the need for a person to scoop coffee grounds into a large filter and thus provides a cleaner approach to making coffee, which is also capable of making a more consistently flavored or strength cup or pot of coffee.

[0006] These and other objects, advantages, purposes and features of the present invention will become more apparent upon review of the following specification in conjunction with the drawings.

[0008] FIG. 2 is a side elevation of the coffee filter unit of FIG. 1;

[0009] FIG. 3 is a top plan view of the coffee filter unit of FIGS. 1 and 2; and

[0010] FIG. 4 is a sectional view of a coffee maker reservoir with coffee filter units disposed therein in accordance with the present invention.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Referring now to the drawings and the illustrative embodiments depicted therein, a coffee filter unit 10 includes an upper filter portion or layer or sheet 12 and a lower filter portion or layer or sheet 14 that are sealed together about their peripheries 16 with coffee grounds disposed therein (FIGS. 1-4). One or more coffee filter units 10 may be placed in a brewing reservoir 18 (FIG. 4), whereby heated water from a coffee maker or coffee brewing device may flow into the reservoir 18 and pass through the coffee filter unit 10 and through a drain or dispensing hole or passageway 18a of the reservoir 18 to brew a cup or pot of coffee, as discussed below. The coffee filter units of the present invention thus provide an integral or unitary pouch or unit that provides both the coffee grounds (at a desired or predetermined amount) and the filtering function (needed in brewing coffee to avoid grounds of coffee being in the brewed coffee), in a self-contained, sealed unit that a user may readily pick up and place in the coffee maker reservoir or basket, as also discussed below.

[0012] The filter portions 12, 14 of the coffee filter unit 10 may comprise any suitable filter material, such as a thin, porous paper filter such as known in the coffee filter arts. The filter portions or sheets are sealed around their peripheries 16 to contain and seal the coffee grounds therein so that the coffee grounds are fully contained in the coffee filter units and the grounds do not fall out of the units. The amount of coffee grounds contained in each coffee filter unit may vary depending on the particular application of the coffee filter units, as discussed below. In the illustrated embodiment, the coffee filter unit 10 is shown as generally circular or disc-shaped, so that the coffee filter unit or units may be readily placed in a typical brewing reservoir of a coffee maker (such as a typical or conventional automatic drip type of coffee maker). By including the filter material with the coffee filter unit, no additional filter is needed to be added to the reservoir when brewing coffee with the coffee filter unit or units of the present invention.

[0013] The coffee filter units of the present invention contain a predetermined or preselected amount of coffee grounds therein, and all of the coffee filter units may have generally about the same amount of coffee grounds therein, or different coffee filter units may be provided that have different predetermined or preselected amount of coffee grounds therein. For example, a first or base coffee filter unit may be provided that has a first amount of coffee grounds therein, such as for brewing a predetermined number of cups of coffee at a predetermined or nominal or weak strength, and one or more second or add-on coffee filter units (that have a second or reduced amount of coffee grounds therein) may be used to adjust the strength and/or quantity of the brewed coffee.

[0014] Thus, if a user likes a "weak" or "normal" cup of coffee, the user may use only the first or base coffee filter unit to brew the number of cups of coffee that can be brewed by that amount of coffee. For example, the first or base coffee filter unit may contain an amount of coffee grounds that will allow the user to make six cups of coffee at a nominal strength (or more cups at a weaker strength or less cups at a greater strength). The second or add-on filters may contain a lesser amount of coffee grounds, such as an amount that would normally make, for example, two cups of coffee at a nominal strength. Thus, the addition of a second or add-on filter may brew a larger pot of coffee at the same strength or may brew the same amount of coffee at a greater strength or robustness. Optionally, other filters may be provided with flavored or sweetened contents, such that a user may select one or more flavor filters or packets to alter or enhance the flavor of the coffee that is being brewed.

[0015] Thus, and with reference to FIG. 4, a user may place a first coffee filter unit 20 at the bottom 18b of a coffee maker reservoir 18. If the user wants to either (a) brew more coffee than the amount of coffee grounds in coffee filter unit 20 is intended for or (b) brew a stronger cup or pot of coffee, then the user may readily add one or more additional coffee filter units 22 into the reservoir 18, such as at or on top of coffee filter unit 20. The coffee filter units may comprise any suitable size and shape, such as generally round or oval or even cube shaped units that may hold a predetermined amount of coffee therein (such as one scoop or two scoops or more or less coffee), whereby a selected number of units may be selected and placed or dropped into the reservoir to achieve the desired overall amount of coffee grounds and thus the desired strength of brewed coffee. The size and shape of the coffee filter units may vary depending on the particular application (for example, the units may be larger or smaller to provide varying amounts of coffee grounds in each selected coffee filter unit). When the desired combination of coffee filter units is placed in the coffee maker reservoir, the coffee maker is actuated and water flows into the reservoir and through all of the coffee filter units 20, 22 and out the dispensing or drain hole 18a at the bottom 18b of the coffee maker reservoir. Optionally, the coffee filter units may be generally disc-shaped (and may have a diameter that is about the size of the diameter of a typical or targeted coffee maker reservoir), and may be readily stacked on top of one another.

[0016] The number of different sized coffee filter units may vary depending on the application, and optionally, all of the coffee filter units may contain generally about the same amount of coffee grounds. The user then selects the desired number of coffee filter units (and optionally the desired combination of different sized coffee filter units) to brew the desired amount of coffee at the desired strength, all without having to deal with scooping coffee grounds from a container.

[0017] Optionally, it is envisioned that a coffee filter unit of the present invention may include flavor enhancements or the like. For example, a user may select a sweetening flavor unit to add to the selected combination of coffee filter units so that the brewed coffee has the desired flavor (such as hazelnut or the like). Optionally, a coffee filter unit may be provided that includes sugar or other sweetening element mixed in with the coffee grounds so the user can brew the desired sweetened coffee and not have to later add sugar or sweetener to the brewed coffee. Other variations in the ingredients or contents of the individual coffee filter units may be implemented while remaining within the spirit and scope of the present invention.

[0018] Therefore, the present invention provides a coffee filter unit system or method that allows a user to brew a desired amount of coffee at a desired strength, without having to scoop coffee out of a container and into a coffee maker reservoir. The present invention provides a cleaner means for brewing a cup or pot of coffee and provides for a more consistent strength of coffee due to the predetermined amount of coffee grounds in each coffee filter unit. Aspects of the present invention are applicable to other brewing devices for brewing other flavored liquids or the like.

[0019] Changes and modifications to the specifically described embodiments may be carried out without departing from the principles of the present invention, which is intended to be limited only by the scope of the appended claims as interpreted according to the principles of patent law including the doctrine of equivalents.
