(8) With reference now to FIGS. 1 and 2, a brewing device 100 may be portable and mountable within, or capable of being attached to, a beverage container 200. The illustrated beverage container 200 is a common coffee mug, although other containers suitable for holding a beverage and having a top opening are contemplated within the disclosure. The brewing device 100 may include a housing 110 dimensioned to hold ground coffee or another brewable material within, and one or more handles or grips 120 to secure housing 110 to beverage container 200. Tea or other brewable materials are also contemplated as being used with brewing device 100. Housing 110 may be constructed from a porous material so as to permit fluid to pass from the interior of to the exterior of housing 110. Additionally, a plurality of perforations 112 may be provided so as to further facilitate the passage of coffee components out of housing 110 that might otherwise be caught in, or filtered by, the porous material of housing 110.

(9) Brewing device 100 may include one handle 120 attached to, or provided on, a side of housing 110, or as illustrated device 100 may include a plurality of handles 120 with each handle provided on, or attached to, various sides of housing 110. Each handle 120 may include a wing 122, an arm 124, and an elbow 126. Wing 122 may be dimensioned to fit over an exterior surface of beverage container 200. In the illustrated embodiments, wing 122 is dimensioned in a square shape having four adjoined sides with arm 124 attached proximate to the top side. Arm 124 connects wing 122 with housing 110, which may be at an elbow 126 attached to housing 110. Elbow 126 may comprise a plurality of sides, with arm 124 attached to a bottom side of elbow 126. As shown in FIG. 1, for instance, a top lip of beverage container 200 may be situated between wing 122 and arm 124. In both illustrated embodiments, handles 120 are illustrated in a deployed position so as to permit attachment to beverage container 200. Handles may also be provided in a stored position, and one or more connection strips 128 may be provided to facilitate adhesion of wing 122 to the side of housing 120. In this regard, connection strips 128 may be positioned to correspond with one or more sides of wings 122. Elbow 126 may be positioned between connection strips 128 as well as between the top and lateral sides of wing 122 in its stored position, while the bottom side of wing 122 and the bottom side of elbow 126 may be substantially aligned in a stored position. Adhesive may be provided on one or more sides of wings 122, on connections strips 128, or both. Other known or to be developed adhesive methods are contemplated within the disclosure, such as a hook and loop fastener. Such adhesive methods and materials may avoid utilization of chemical components that would alter the composition, and consequentially the flavor or aroma, of the coffee during an infusion process described in accordance with this disclosure.

(10) Housing 110 may also include a sealable opening 130. In some embodiments, opening 130 may be sealed with coffee, tea, or another brewable substance stored within while in other embodiments opening 130 may be unsealed and the brewable substance selected and placed within housing 110 through opening 130. Water may also be poured into opening 130 in accordance with infusion processes described herein.

(11) Housing 110 may be composed of a porous material, such as paper, and further may include a plurality of perforations 112 provided on one or more sides of housing 110. Each side may have a dimension of about 90 mm in height, defined as the distance between the edge of opening 130 and a base edge of housing 110, and about 70 mm in width, defined as the distance between lateral edges of housing 110. These dimensions may permit housing 110 to be portable and sufficiently dimensioned to fit within a standard coffee mug, as shown for instance in FIG. 1. Perforations 112 may each have a diameter of about 2.33 mm. About 35 perforations may be provided on opposing sides of housing 110 for a total of about 70 perforations.

(12) An infusion or brewing process may be conducted utilizing device 10 in order to brew coffee, tea, or another brewable component through infusion with water. An infusion by immersion may occur where water is in continuous contact with the brewable substance stored in housing 110. In this method, water may be placed in beverage container 200 and housing 110 may be submerged into container 200. An infusion by dripping may occur where water flows over the brewable substance and drips into container 200. In this method, water may be poured over a brewable substance placed in housing 110, which then drips into container 200.

(13) Testing was conducted to determine an optimal number of perforations 112 as well as an optimal size of each perforation 112 for brewing coffee. Testing was conducted to determine improvements in coffee flavor, color, aroma, and time of infusion required as a result of the brewing process. Initially, several sized needles were tested for generating perforations 112, but a needle size of about 2.33 mm was selected due to the type of fiber comprising paper filter housing 110. Smaller perforations would practically close while larger perforations would permit the unwanted passing of coffee solids. Testing was then conducted to determine an optimal number of perforations 112. 10 total perforations were initially tested, with 5 on opposing sides, but the results showed no improvement and the housing paper was saturated similarly to no perforations existing. 20 total perforations were then tested, with 10 on opposing sides, and results again showed no improvement and the housing paper was similarly saturated. 30 total perforations were then tested, 15 on each side, and a slight improvement was shown in the passing of the oils as well as an improvement in infusion time, however the housing paper remained similarly saturated. 40 total perforations were then tested, 20 on each side, with results showing a reduction of housing paper saturation and values of flavor increased, although color remained unimproved and there was no appreciable improvement of infusion time from testing with 30 total perforations. 50 total perforations, 25 on each side, were tested and improvement of all values to the coffee were demonstrated. 60 total perforations, 30 on each side, were tested and values to the coffee further improved from the testing of 60 total perforations. 70 total perforations, with 35 on each side, were then tested with the best results achieved of any testing. Specifically, testing of 70 total perforations demonstrated: the best outflow of coffee oils and their beneficial properties; best coffee flavor because the time of contact of the coffee is sufficient to allow the release of the oils, obtain the highest consistency and strength of the flavor, and accordingly contribute to a high body to the final flavor with good intensity; the best aroma of the coffee due to higher intensity; the best consistency to the coffee due to the freer flowing oils; and best performance in other qualitative data, such as a reduction of filtering time about 14 seconds, with no noticeable problem or hindrance. Additional perforations were tested, which showed improved performance from no or few perforations, but not as optimal of a performance as 70 perforations. 80 total perforations, with 40 on each side, were tested with good time of extraction performance, but the contact with the water was too quick to achieve optimal infusion thereby weakening the flavor and color compared to the 70 perforation test. 78 perforations were tested, with 39 on each side, with virtually the same performance as 80 perforations. 72 perforations were tested, with 36 on each side, with similar performance to the 70 perforations however the arrangement of perforations caused some clustering of perforations. Accordingly, between about 30 perforations to about 80 perforations showed improved performance, with substantial improvement occurring with about 50 to about 60 perforations, and optimal improvement achieved with about 70 perforations. With respect to the coffee tested, a fine, medium, and coarse grind were tested with the medium grind performing the best for allowing optimal extraction of the coffee's properties while not allowing solids to pass as was possible with the fine coffee grind.

(14) With reference now to FIG. 3, in an embodiment of housing 110 featuring 70 perforations 112, 35 may be placed on a side of housing 110 surrounding a portion of connection strips 128. Perforations 112 may be placed around connection strips 128 so as to avoid flow interference due to the positioning of the strips 128 or the components of handle 120 in either the deployed or stored position. Two rows of perforations 112 may be each placed around the left, right, and bottom sides of connection strips 128. As shown in the illustrated embodiment: the perforations 112 proximate to the left side may include 9 evenly spaced perforations 112; the perforations 112 proximate to the right side may include 11 evenly spaced perforations 112; the perforations proximate to the bottom side may include 11 evenly spaced perforations 112; and an additional 2 perforations may be provided in the bottom left corner as well an additional 2 perforations may be provided in the bottom right corner. In one embodiment of housing 110 having a height dimension of about 90 mm and a width dimension of about 70 mm, perforations 112 may be spaced at the following dimensions: left side perforations 112 spaced about 4.5 mm from center to center; right side perforation spaced about 9.5 mm from center to center; the bottom side perforations spaced about 9.5 mm from center to center; and the corner perforations spaced about 4 mm from each other while each corner perforation closest to the strips 128 may be aligned with the row of side and bottom perforations closest to strips 128. The spacing dimensions may adjusted +/−0.5 mm while still obtaining optimal results, and +/−1.5 mm while still obtaining improved results. This dimensional arrangement of perforations may avoid clustering to provide evenly distributed flow of coffee out of housing 110.
