Brief Patent Description - Full Patent Description - Patent Application Claims
TECHNICAL FIELD [0001]Embodiments of the present invention relate generally to the field of filters, and more specifically, to a filter having one or more indicators thereon as an aid to filling the filter with a predetermined amount of material to be filtered. BACKGROUND [0002]Beverage filters, for example, coffee filters, are known, and typically include a membrane such as a paper, a cloth, or a mesh adapted to hold a material to be filtered but which allow a filtrate to pass through upon adding a liquid, such as hot water. Typically, as in the case of making a coffee beverage, when a selected amount of coffee beverage is desired, a corresponding amount of coffee grounds is required to be placed in the filter. The amount of coffee grounds is typically quantified as a predetermined number of scoops or spoonfuls. Sometimes, while in the process of making coffee, a person may lose count of the number of scoops, or spoonfuls, of coffee grounds placed into the filter, and either have to start over again or risk making a stronger or weaker beverage (e.g. coffee) than desired. In addition, some people, when making coffee do not have the time, or the patience, to carefully fill each scoop or spoonful to the proper level, and/or count the proper number of scoops or spoonfuls dumped into the filter.

[0019]FIGS. 1A, 1B, and 1C are respective front, perspective, and top front views of a filter 10 illustrating various embodiments of the present invention. In FIG. 1A filter 10 is illustrated in a first configuration 12. In FIGS. 1B and 1C the filter 10 is illustrated in a second configuration 14. The filter 10 may include a membrane 16 adapted to hold a material (not shown) to be filtered, and may be adapted to allow a filtrate (not shown) to pass through. The filter 10 may also include an indicator 18 on the membrane adapted to indicate a quantity of the material to be placed in the filter 10. Various embodiments may include one or more indicators. The embodiment illustrated in FIGS. 1A-1C may include multiple indicators, for example, indicators 18, 20, 22, 24, 26, and 28, respectively, adapted to indicate quantities of, for example, 2, 4, 6, 8, 10, and 12 unit measures of a quantity of the material to be placed in the filter 10, such as volume, weight, or other quantities. For example 2, 4, 6, 8, 10, or 12 scoops or spoonfuls of material, or cups of coffee. The filter 10 may include labels 30 at or near each of the indicators 18, 20, 22, 24, 26, and 28 to identify the respective quantities. The indicators 18, 20, 22, 24, 26, and 28 may be, for example, one or more of printed, embossed, silk-screened, stained, or the like onto the membrane 16. Various embodiments may have additional labels 32 arranged to be readable from a number of orientations and/or sides. The labels 30 and/or 32, if present, may be one or more of printed, embossed, silk-screened, or stained onto the membrane. Various embodiments may use only labels as indicators. Other embodiments may have short lines on one or both sides of the labels as one or more indicators. [0020]In various embodiments the material may be, for example, coffee grounds and the filtrate may be coffee, and the filter 10 may be a coffee filter having a sidewall 17 and one or more indicators 18 on the sidewall 17 may be adapted to indicate one or more predetermined quantities of coffee grounds substantially corresponding to one or more predetermined quantities of a coffee product.
