Description

BACKGROUND

There are numerous devices available today for making a single-serve brewed beverage, such as the single-server brewers shown and described in, for example, U.S. Pat. Nos. 6,708,600, and 6,079,315, the disclosures of which are hereby expressly incorporated by reference herein.

In a typical single-serve beverage brewer, a disposable beverage filter cartridge containing a dry beverage medium (such as tea or coffee) is disposed within a filter cartridge holder or brewing holster. To brew the beverage, the filler cartridge is pierced by inlet and outlet probes to accommodate a through-flow of metered hot water. The hot water infuses the dry beverage medium contained in the cartridge to thereby produce a single serving of the beverage. After the beverage is brewed, the cartridge is removed from the cartridge holder and it is discarded.

By requiring the use of the disposable cartridges, the consumer is limited to the beverage selection of the cartridges on hand. Moreover, with each cartridge being disposed of after use, there is much needless waste. Thus there is a need for a reusable cartridge filter suitable for use with a beverage brewer described above that can be used with any desired dry beverage medium (coffee, tea, etc.).

SUMMARY

The beverage brewing device is configured for use with a beverage brewer having an inlet probe for dispensing water and an outlet probe. The beverage brewing device includes a body defining a brew chamber configured to contain a dry beverage medium and at least one outlet probe receptacle defined in the body and extending upwardly from a bottom surface of the body. The at least one outlet probe receptacle is sized and configured to receive an outlet probe of a beverage brewer. A lid is removably securable to the body and is engageable with the body to selectively enclose a top opening of the body. An inlet probe opening is defined in the lid for receiving an inlet probe of the beverage brewer. At least one filter is defined within in the body, wherein the filler is configured to retain a dry beverage medium within the brow chamber while allowing a brewed beverage to pass through the brew chamber.

DETAILED DESCRIPTION

A reusable beverage brewing device 20 formed in accordance with a first exemplary embodiment of the present disclosure may best be seen by referring to FIG. 1. The beverage brewing device 20 is suitable for use with a multi-use, single-cup beverage brewer, such as a coffee brewer B. More specifically, the beverage brewing device 20 is configured to contain a preselected dry beverage medium, such as coffee grounds, and interface with inlet and outlet probes I and O of a beverage brewer B when received within a brewing holster H (shown in hidden lines only) of the beverage brewer B to brew a beverage for dispensing into a cup C. For instance, the beverage brewing device 20 is designed to work with most Keurig™ single-cup beverage brewers, which is similar to the beverage brewer B depicted in FIG. 1. However, it should be appreciated that the beverage brewing device 20 may instead be used with any suitable beverage brewer. Accordingly, the illustrations and depictions set forth herein shall not be seen as limiting the scope of the claimed subject matter.

Referring to FIGS. 2 and 3, the beverage brewing device 20 will now be described in detail. The beverage brewing device 20 has an overall shape and configuration to be removably received within the brewing holster H of the beverage brewer B. More specifically, the beverage brewing device 20 has a substantially cup-shaped, cylindrical body 26 that corresponds in shape and size to the interior of the brewing holster H of the beverage brewer B.

The cup-shaped body 26 has a curved, substantially vertical sidewall 28 extending between an open top end 30 and a closed bottom end 34 defined by a substantially flat bottom surface 42. The sidewall 28 and closed bottom end 34 define a brew chamber 36 within the interior of the cup-shaped body 26. The brew chamber 36 is sized and shaped to receive the dry beverage medium, such as coffee grounds.

A filter 38 is disposed within openings in the body 26 for filtering water as it passes through the brew chamber 36. More specifically, the filter 38 allows a brewed beverage to pass therethrough while retaining the dry beverage medium within the body 26. In that regard, any suitable reusable, durable filter may be used, such as a micro-screen mesh filter made from metal (such as gold or stainless steel, gold-tone filters), plastic, or fabric. In this manner, the brewed beverage, such as coffee, flows through the dry beverage medium contained within the body 26 and ultimately through the filter 38 and into a cup C positioned be to the brewing holster H of a beverage brewer B.

Although the filter 38 may be disposed in any suitable openings within the body 26, in the depicted embodiment, the filter 38 is disposed within openings in the sidewall 28 and the bottom surface 42 of the body 26. Specifically, the sidewall 28 includes a first pair of openings 40 disposed opposite a second pair of substantially identical openings 44 (only partially shown for ease of illustration). The bottom surface 42 similarly includes a first pair of openings 48 disposed opposite a second pair of substantially identical openings 50. The brewed beverage may flow through the openings 40 and 44 in the sidewall and through the openings 48 and 50 in the bottom surface 42 into the brewing holster H. The brewing holster H and/or the beverage brewer B may include suitable structure (not shown) to funnel or otherwise direct the brewed beverage down into the cup C for consumption.

The filter 38 may be secured within the body 26 in any suitable manner such that the edges of the filter 38 do not form an abrupt edge within the interior of the brew chamber 36. For instance, the filter 38 may be molded within the body 26 or otherwise fused into the sidewall 28 and the bottom surface 42 of the body 26. In this manner, a smooth, substantially seamless transition is defined between the filter 38 and the body 26. With this substantially seamless transition, the filter 38 has no exposed edges or frayed wires. As such, any dry beverage medium, such as coffee grounds, will not become lodged within crevices that would otherwise be created by any exposed or frayed edges.

As noted above, the closed bottom end 34 is defined by a substantially flat bottom surface 42. With a substantially flat bottom surface 42, the beverage brewing device 20 can be easily set onto a surface, such as a counter, and the brew chamber 36 can be filled with the desired dry beverage medium. In other words, the substantially flat bottom surface 42 allows for hands-free filling and less mess when filling the brew chamber 36 with, for instance, coffee grounds.

With the brew chamber 36 filled with, for instance, coffee grounds, the beverage brewing device 20 may be disposed within a brewing holster H of a beverage brewer B to brew a beverage. As discussed briefly above, the beverage brewing device 20 is configured for use within a brewing holster of a beverage brewer having an outlet probe O that extends upwardly into the brewing holster compartment of the beverage brewer B. In that regard, the body 26 includes first and second opposing outlet probe receptacles 54 and 58 extending upwardly from the bottom surface 42 of the body 26. Each outlet probe receptacle 54 and 58 defines an opening of a sufficient size and is of a sufficient depth to receive the outlet probe O so that the beverage brewing device 20 may be fully received within the brewing holster H. Moreover, the receptacles 54 and 58 define a continuous extension of the bottom surface 42 to fluidly isolate the outlet probe O from the brew chamber 36 when the outlet probe O is received within one of the first and second outlet probe receptacles 54 or 58.

The first and second outlet probe receptacles 54 and 58 are disposed on opposite sides of the bottom surface 42 of the body 26 such that the beverage brewer 20 may be configured in one of two positions to seat within the brewing holster H (i.e., with one of the first and second opposing outlet probe receptacles 54 and 58 receiving the outlet probe O). It should be appreciated that the body 26 may instead include only one outlet probe receptacle such that the beverage brewer 20 is positionable in only one position within the brewing holster H. As yet another alternative, three or more outlet probe receptacles may instead be formed within the body 26 such that the beverage brewer 20 may be configured in three or more positions within the brewing holster. Even further, it should be appreciated that the outlet probe receptacle may instead be defined as a single annular receptacle extending along the circumferential edge of the bottom surface 42 of the body 26. In this regard, the beverage brewing device 20 could be seated within the brewing holster H in an unlimited number of positions with the outlet probe O received anywhere in the annular receptacle. Thus, the descriptions and illustrations provided herein should not be seen as limiting.

Each of the first and second opposing outlet probe receptacles 54 and 58 extend upwardly from the bottom surface 42 of the body 26 to receive the outlet probe O when the beverage brewing device 20 is received within the brewing holster H. In this manner, the bottom surface 42 of the body 26 can remain substantially flat to provide at least the benefits noted above, with the receptacles 54 and 58 extending upwardly therefrom into the brew chamber of the body 26 to receive the outlet probe O.

Moreover, by forming the outlet probe receptacles 54 and 58 within the bottom surface 42 and positioning the outlet probe receptacles 54 and 58 to engage the outlet probe O in one of two positions (rather than, for instance, having an entire bottom cavity suitable to accept the outlet probe in any number of positions), the body 26 can effectively have a deeper, larger interior brew chamber capacity. A larger brew chamber 36, as can be appreciated by one of ordinary skill in the art, can hold more, dry beverage medium, such as coffee grounds, and can help create more turbulence during brewing for a more uniform, more efficient, and more thorough beverage extraction. The increased internal volume of the brew chamber 36 therefore accommodates consumers that prefer a stronger brew or more ounces of brewed coffee.

The body 26 is also formed such that its interior surface, including the surface defined by the outlet probe receptacles 54 and 58, has substantially rounded edges. As a result, the interior surface of the body 26 includes no hard-edged transitions and no crevices or corners where coffee grounds or other dry beverage mediums can get stuck. This helps ensure an easier cleanup for the consumer after the use of the beverage brewing device 20. In this manner, after each use, the beverage brewing device 20 may be quickly cleaned and reused for brewing another beverage.

To help align the beverage brewing device 20 within the brewing holster H such that the one of the first and second opposing outlet probe receptacles 54 and 58 receives the outlet probe O, the beverage brewing device 20 may include first and second opposing grips 62 and 66 that are receivable within correspondingly shaped cavities R (only one cavity R shown in hidden lines in FIG. 1 for clarity) in the brewing holster H when the beverage brewer 20 is disposed in the brewing position. The first and second grips 62 and 66 protrude from an exterior surface of the curved sidewall 28 of the body 26. The grips 62 and 66 may be any suitable shape and size such that they are receivable correspondingly shaped first and second cavities in the brewing holster H. In the depicted embodiment, each of the first and second grips 62 and 66 include a curved lower grip portion 70 that is somewhat semi-circular in shape. The curved lower grip portion 70 is receivable within the correspondingly shaped curved cavity R defined within the brewing holster H.

With the curved lower grip portion 70 of each of the first and second grips 62 and 66 received within the correspondingly shaped curved cavity R of the brewing holster the beverage brewing device 20 is aligned within the brewing holster H such that one of the first and second opposing outlet probe receptacles 54 and 55 receives the outlet probe O. Thus, the positioning of the grips 62 and 66 within the cavities R ensures that the body 26 is positioned within the brewing holster H in only in one of two positions, separated by one hundred eighty degrees (180°).

In addition to positioning the beverage brewing device 20 within the brewing holster the first and second grips 62 and 66 are sized and configured to be graspable by a user for helping to insert and remove the beverage brewing device 20 from within the brewing holster H. In that regard, a substantially flat upper grip portion 74 extends across the diameter of the semi-circular shape of the curved lower grip portion 70. Moreover, the first and second grips 62 and 66 are formed near the upper open end of the body 26 such that the upper grip portion 74 is sufficiently graspable by a user to remove the brew device 20 from within the brew holster H. For instance, the first and second grips 62 and 66 may be formed on the body 26 such that at least the upper grip portion 74 protrudes from an upper open end of the brewing holster H when the beverage brewing device 20 is received within the brewing holster H in the brewing position.

To aid in grasping the first and second grips 62 and 66, the upper grip portion 74 and lower grip portion 70 define a gripping cavity 78 that beverage brewing device 20 extends from the outer edge of the lower and upper grip portions 70 and 74 to the body 20 (or near the body 26). The gripping cavity 78 may be sized, for instance, to accommodate a user's fingertip when gripping the upper grip portion 74 to insert and remove the beverage brewing device 20 from within the brewing holster H.

The first and second grips 62 and 66 are also designed to help dissipate heat generated within the brew chamber 36 of the body 26 when brewing a beverage. The lower grip portion 70 and upper grip portion 74 extend from the outer surface of the sidewall 28 of the body 26 with a cavity 78 defined by the lower and upper grip portions 70 and 74. As such, the surface area of the lower and upper grip portions 70 and 74 are maximized to help dissipate heat. The heat-dissipating design of the first and second grips 62 and 66 helps insulate the user from the post-brewing temperature of the beverage brewing device 20. Accordingly, the beverage brewing device 20 can be safely and more quickly removed from the brewing holster H after the beverage is brewed.

Referring additionally to FIG. 4, before positioning the body 26 within the brewing holster H for brewing a beverage, the brewing chamber 36 is first enclosed by a removable lid 84. The lid 84 is sized and configured on an exterior side to mate with the inlet probe I of a beverage brewer B when the beverage brewing device 20 is received within a brewing holster H. (See FIG. 2). Moreover, the lid 84 is sized and configured on an interior side to seat within the top opening defined by the body 26 and distribute water received from the inlet probe I for brewing. (See FIG. 3).

Referring to FIGS. 2 and 4, the exterior side of the lid 84 suitable for mating with the inlet probe I of a beverage brewer B will first be described in detail. The lid 84 includes a lid body 86 that is substantially circular in overall shape to match the circular top opening defined by the cylindrical or cup-shaped body 26 of the beverage brewing device 20. The lid body 86 defines a substantially flat upper surface such that when the lid 84 is closed, the upper surface of the lid body 86 is suitable to mate with a flat portion of an inlet probe assembly of the beverage brewer B (see FIG. 4).

When closed, the lid 84 is suitable for receiving the inlet probe I of the beverage brewer B and then distributing the water from the inlet probe I into the brew chamber 36 of the beverage brewing device 20 for brewing a beverage. In that regard, a dispersion cone opening 88 is defined in substantially the center of the lid body 86. The dispersion cone opening 88 is configured to place the inlet probe I into fluid communication with a dispersion cone 124 suitable for maximizing the water volume intake capacity of water from the inlet probe I.

The dispersion cone opening 88 is in fluid communication with a stepped receptacle 90 formed within the lid body 86 that is sized and configured to sealingly receive an elastomeric receptacle plug 92 therein. The stepped receptacle 90 is substantially circular in overall shape and extends downwardly from the substantially flat upper surface of the lid body 86. The stepped receptacle 90 includes a transverse plug shoulder 94 surrounding the dispersion cone opening 88 that is configured to abut against a receptacle shoulder portion 96 of the receptacle plug 92 when the plug 92 is received therein.

The stepped receptacle 90 further defines an annular protrusion 98 formed inwardly of the transverse plug shoulder 94 (i.e., toward the dispersion cone assembly 110) that is configured to releasably receive an annular recess 102 of the receptacle plug 92. The interface of the annular protrusion 98 and the annular recess 102 defines a seal-tight fit between the stepped receptacle 90 and the receptacle plug 92. Moreover, when the annular recess 102 is received on the annular protrusion 98, a snap-fit is defined therebetween to indicate to the user that the receptacle plug 92 is fully received within the stepped receptacle 90.

When received within the stepped receptacle 90, the receptacle plug 92 is sized and configured to sealingly engage the inlet probe or its surrounding inlet probe assembly. More specifically, the receptacle plug 92 defines a transverse inlet probe shoulders 104 surrounding an inlet probe opening 106. The inlet probe shoulder 104 is sized to engage an inlet probe shoulder S surrounding the inlet probe I of the beverage brewer B. In that regard, the inlet probe opening 106 is smaller in diameter than the opening defined by the stepped receptacle 90 and the dispersion cone opening 88.

When the inlet probe assembly is lowered for brewing, the inlet probe shoulder S is lowered into sealing engagement with the inlet probe shoulder 104 and the inlet probe I protrudes through the inlet probe opening 106. The inlet probe I is also held in substantial fixed relation relative to the beverage brewing device 20 when the inlet probe shoulder S is sealed against the receptacle plug 92 for brewing. It should be appreciated that the receptacle plug 92 may instead be configured to seal against the inlet probe I or another portion of the inlet probe assembly in another manner without departing from the scope of the present disclosure. The inlet probe protrudes through the inlet probe opening 106 and down through the dispersion cone opening 88 toward the interior side of the lid 84 to distribute water for brewing.

Referring to FIGS. 3 and 4, the interior side of the lid 84 suitable for enclosing the brew chamber 36 within the body 26 and for distributing water received from the inlet probe I for brewing will now be described in detail. The interior of the lid 84 is sized and configured to sealingly mate with the top open end of the body 26. In that regard, a circular or annular protrusion 114 is concentrically formed on the interior surface of the lid 84 that is sized and shaped to seat within the lop opening defined by the body 26 of the beverage brewing device 20.

An annular seal 116 is disposed within an annular recess 118 extending around the annular protrusion 114. The annular seal 116 is configured to seal against the interior surface of the body 26 when the annular protrusion 114 is received within the top opening of the body 26. Any suitable seal may be used, such as a silicone seal that is heat resistant for withstanding the temperatures of brewing. The annular seal 116 defines a watertight seal between the annular protrusion 114 and the body 26 when the annular protrusion 114 is seated within the top opening defined by the body 26. In this manner, when the lid 84 is moved into the closed position, the lid 84 sealingly encloses the brew-chamber 36 of the beverage brewing device 20 for brewing.

The lid 84 is hingedly secured to the body 26 such that the lid 84 may be moved between open and closed positions. The lid 84 may be hingedly secured to the body 26 in any suitable manner, such as through an integrated flexible hinge 120 extending between the lid body 86 and a flanged rim 122 formed substantially transversely around the top open end of the body 26. The flexible hinge 120 defines a hinge axis that is substantially tangent to the outer circumference of the lid 84 and the flanged rim 122. In this manner, the flexible hinge 120 allows the lid 84 to move between an open position, wherein the interior surface of the lid body 86 can be positioned substantially co-planar with the upper surface of the flanged rim 122 (see FIG. 3), and a closed position, wherein the interior surface of the lid body 86 is adjacent to or abutted against the upper surface of the flanged rim 122 (see FIG. 4).

When the lid 84 is in the closed position, as shown in FIG. 4, the inlet probe I is positioned to extend through the inlet probe opening 106 in the receptacle plug 92 to release water into a dispersion cone 124 formed on the interior surface of the lid body 86. The dispersion cone 124 is configured to help distribute water released from the inlet probe I.

More specifically, the dispersion cone 124 substantially encloses the dispersion cone opening 88 to place the dispersion cone opening 88 into fluid communication with the brew chamber 36. In that regard, the dispersion cone 124 includes a dispersion cone body having a hollow cylindrical portion 128 extending from the interior surface of the lid body 86 and surrounding the dispersion cone opening 88. The dispersion cone body further includes a hollow conical portion 132 extending from the cylindrical portion 128 to enclose the dispersion cone opening 88. A plurality of openings 136 is formed within the conical portion 132 to place the dispersion cone 124 into fluid communication with the brew chamber 36 and transfer fluid from the inlet probe I into the brew chamber 36.

When the lid 84 is in the closed position, as depicted in FIG. 4, the dispersion cone 124 extends downwardly at least partially into the brew chamber 36. In this manner, when a dry beverage medium, such as coffee grounds is disposed within the brew chamber 36, the dispersion cone 124 can help tamp, or pack the coffee grounds G into the brew chamber 36 for a better brew. As is well known in the coffee brewing industry, tamping coffee grounds firmly and uniformly within a brew chamber forces water to flow through the grounds in a manner that extracts the best of the coffee ground's flavors. With firm and even tamping, the water has no choice but to flow through all of the coffee grounds uniformly. The same can be appreciated with other types of dry beverage mediums, such as tea.

When the brew chamber 36 is filled with coffee grounds G up to a certain minimum or maximum level, which can be indicated to the user by a fill line indicator 142, the dispersion cone 124 is forced downwardly into the coffee grounds G when the lid 84 is closed, thereby occupying space within the brew chamber 36 and tamping the coffee grounds G within the brew chamber 36. In that regard, the overall size or height of the cylindrical portion 128 of the dispersion cone 124 may be varied to change the depth of the dispersion cone 124 within brew chamber 36. Thus, for a user who prefers, for instance, brewed coffee that is less strong in flavor, the dispersion cone 124 could extend much deeper within the brew chamber 36 to reach and tamp coffee grounds at a lower fill line level (which would therefore produce a less strong brew). Thus, it should be appreciated that the embodiment described and illustrated herein is exemplary only and is not intended to limit the scope of the claimed subject matter.

In addition to tamping the coffee grounds G within the brew chamber 36, the dispersion cone 124 helps distribute the water from the inlet probe I to the coffee grounds G to aid in driving water flow uniformly through the coffee grounds G. Referring to FIG. 4, with the inlet probe I sealingly received within the receptacle plug 92, the water is first directed into a small, well-defined, sealed inlet probe opening 106 defined by the receptacle plug 92 and then expanded into the dispersion cone 124 for greater water dispersion capacity.

The dispersion cone 124 defines a water chamber for receiving and pressurizing water released from the inlet probe I. The water from the inlet probe I fills the chamber defined by the dispersion cone 124 and then slowly exits the dispersion cone 124 through the smaller openings 136. The gradual flow of water through the openings 136 in the dispersion cone 124 helps prevent the coffee grounds G from being soaked all at once. The shape and configuration of the dispersion cone 124 also positions the openings 136 within the brew chamber 36 in an even, distributed manner to help direct water in a substantially even, uniform manner throughout the coffee grounds G. This allows for a better extraction of the brewed beverage from the coffee grounds G and, as a result, a better cup of brewed coffee.

The sealed inlet probe opening 105 defined by the receptacle plug 92 also helps maximize the pressure of the water flowing through the dispersion cone 124 during the brewing process. Referring to FIG. 4, with the inlet probe I sealingly received within the inlet probe opening 106 of the receptacle plug 92, water from the inlet probe I flowing at a first flow rate is forced into the sealed area defined by the inlet probe I, the inlet probe shoulder S, the receptacle plug 92, and the dispersion cone 124. The water flows out of the small dispersion cone openings 135 at a second, slower flow rate due to the smaller opening 136 in the dispersion cone 124. In this manner, the water pressure is maximized as it flows out of the dispersion cone openings 136 into the coffee grounds G for extraction of the brewed beverage. This helps ensure that the water exiting the dispersion cone 124 reaches the coffee grounds packed near the interior sidewall 28 of the beverage brewing device 20 rather than merely dripping down just below the dispersion cone 124. In this manner, a more uniform, even brew will result.

The body 26 and lid 84 of the beverage brewing device 20 may be made from any suitable material, such as plastic. For instance, the body 26 and lid 84 may be made from a plastic that is free of Bisphenol A (BPA) and that is dishwasher-safe and durable. The body 26 and lid 84 may also be manufactured in any suitable manner. As a nonlimiting example, the body 26 and lid 84 may be made through plastic injection molding as a single unit with the flexible hinge 120 connecting the body 25 and lid 84.

In reference to FIGS. 1-4, the manner in which the beverage brewing device 20 may be used will now be described. Upon selecting a dry beverage medium to be brewed, such as coffee grounds, tea, etc., the beverage brewing device 20 may be set on a counter or other device such that the lid 84 may be moved into the open position. The lid 84 is moved about the axis defined by the flexible hinge 120 into the open position, and the brew chamber 36 is filled with a desired amount of dry beverage medium, such as coffee grounds G, as shown in FIG. 4. For the strongest brew, the brew chamber 36 is filled up to the fill line 142 (see FIG. 3) such that the coffee grounds G will be tamped by the dispersion cone 124 when the lid 84 is closed.

With the coffee grounds G or another dry beverage medium added to the brew chamber 36, the lid 84 may be moved into the closed position, as shown in FIG. 4. With the lid 84 in the closed position, the annular protrusion 114 is received within the open top end 30 of the body 26, and the annular seal 116 is sealed against the interior surface of the body 26. Moreover, if the coffee grounds G have been filled up to the fill line 142, the dispersion cone 124, upon closing the lid 84, will tamp the coffee grounds G within the brew chamber 36.

With the coffee grounds G or other dry beverage medium disposed within the beverage brewing device 20, the beverage brewing device 20 may be inserted into the beverage brewer B for brewing a beverage. In that regard, the beverage brewing device 20 is disposed within a brewing holster H of a beverage brewer B such that the first and second grips 62 and 66 are received correspondingly shaped cavities R in the brewing holster 11. With each of the first and second grips 62 and 66 received within a correspondingly shaped curved cavity R of the brewing holster H, the beverage brewing device 20 is aligned within the brewing holster H such that one of the first and second opposing outlet probe receptacles 54 and 58 in the beverage brewing device 20 receives an outlet probe O of the beverage brewer B.

With the beverage brewing device 20 received within the brewing holster H, the inlet probe assembly is lowered into engagement with the beverage brewing device 20, either manually or automatically (depending on the configuration of the beverage brewer B). The inlet probe assembly is lowered until the inlet probe shoulder S abuts against the inlet probe shoulder 104 of the receptacle plug 92 and the inlet probe I is disposed within the inlet probe opening 106 of the receptacle plug 92, as shown in FIG. 4.

With the inlet probe I in the brewing position, a beverage may be brewed according to the beverage brewer instructions. As can be appreciated by one of ordinary skill, to brew a beverage, the beverage brewer B dispenses heated water through the inlet probe I, which passes through the inlet probe opening 106 of the receptacle plug 92 and into the dispersion cone 124. The heated water, which becomes at least somewhat pressurized within the dispersion cone 124, passes through the dispersion cone openings 136 to substantially evenly and uniformly soak the coffee grounds G within the brew chamber 36. The brewed beverage passes through the coffee grounds G and out of the openings 40, 44, 48, and/or 50 in the body 26 of the beverage brewing device 20 and into a cup C or other container positioned below the brewing holster H in the beverage brewer B. After brewing a beverage, the beverage brewing device 20 can be removed from the brewing holster and cleaned for subsequent use.

It can be appreciated from the foregoing that the beverage brewing device 20 can be used with a typical single-server beverage brewer B, such as that shown and described with reference to FIGS. 1 and 4, without retrofitting or modifying the beverage brewer B. With the exception of the need to add a dry beverage medium to the brew chamber 36 of the beverage brewing device 20, the beverage brewing device 20 functions based on substantially the same beverage brewing extraction principles for which the single-server beverage brewer was originally made.

Referring to FIGS. 5-7, a reusable beverage brewing device 220 formed in accordance with a second exemplary embodiment of the present disclosure will now be described. The reusable beverage brewing device 220 is substantially similar to the reusable beverage brewing device 20 described above; and thus, the description will be primarily based on the differences between the first and second embodiments. In that regard, many of the same or similar features have been labeled with the same reference number, with the features for the reusable beverage brewing device 220 labeled in the 200 series.

The beverage brewing device 220 has a substantially cup-shaped, cylindrical body 226 and a lid 284 hingedly secured thereto that is moveable between open and closed positions. The body 226 and lid 284 of the beverage brewing device 220 are made from a suitable metal, such as stainless steel. Other suitable durable metals may also be used, such as aluminum, brass, etc.

The body 226 and lid 284 may be manufactured using any suitable or well-known techniques for forming metal, including extruding, punching, welding, riveting, etc. It should be appreciated that although the beverage brewing device 220 is described as being made from a suitable metal, other materials, such as plastic, may instead be used without departing from the scope of the present disclosure.

The substantially cup-shaped, cylindrical body 226 corresponds in shape and size to the interior of the brewing holster H of the beverage brewer B. The cup-shaped body 226 has a curved, substantially vertical sidewall 228 extending between an open top end 230 and a closed bottom end 234 defined by a substantially flat bottom surface 242. The sidewall 228 and closed bottom end 234 define a brew chamber 236 within the interior of the cup-shaped body 226.

At least one filter is defined within the body 226 of the brewing device 220 for filtering water as it passes through the brew chamber 236. More specifically, first and second opposing filter areas 240 and 244 are defined within the sidewall 228, and first and second opposing filter areas 248 and 250 are defined within the bottom surface 242. The filter areas may be defined by a pattern of micro perforations sized to allow a brewed beverage to pass therethrough while retaining the dry medium within the body 226. The micro perforations may be formed in any suitable manner, such as by laser cutting.

A micro perforated plate may be used to define the sidewall 228 or bottom surface 242, with the micro perforations formed within the filter areas 240, 244, 248, or 250. In the alternative, a micro perforated plate may first formed and then integrated within the sidewall 238 or bottom surface 242. For instance, to define the sidewall filter areas 240 and 244, micro perforated plates may be welded within openings in the first and second opposing filter areas 240 and 244.

By forming the micro perforations with a micro perforated plate that defines the sidewall 228 or bottom surface 242, or a plate that is otherwise welded within an opening, within the brewing device 220, the edges of the micro perforated plate do not form an abrupt edge within the interior of the brew chamber 36. In this manner, a smooth, substantially seamless transition is defined between the filter area 240, 244 and the body 226. As such, any dry beverage medium, such as coffee grounds, will not become lodged within crevices that would otherwise be created by any exposed or frayed edges.

The brewed beverage may flow through the micro perforations in the filter areas 240 and 244 in the sidewall 228 and through the micro perforations in the filter areas 248 and 250 in the bottom surface 242 into the brewing holster H. The brewing holster H and/or the beverage brewer B may include suitable structure (not shown) to funnel or otherwise direct the brewed beverage down into the cup C for consumption.

Before disposing the beverage brewing device 220 within the brewing holster H for brewing, the brew chamber 236 must first be filled with a desired dry beverage medium, such as coffee grounds. As noted above, the closed bottom end 234 is defined by a substantially flat bottom surface 242. With a substantially flat bottom surface 242, the beverage brewing device 220 can be easily set onto a surface, such as a counter, and the brew chamber 236 can be filled with the desired dry beverage medium. In other words, the substantially flat bottom surface 242 allows for hands-free filling and less mess when filling the brew chamber 236 with, for instance, coffee grounds.

With the brew chamber 236 filled with, for instance, coffee grounds, the beverage brewing device 220 may be disposed within a brewing holster H of a beverage brewer B to brew a beverage. As discussed briefly above, the beverage brewing device 220 is configured for use within a brewing holster H of a beverage brewer having an outlet probe O that extends upwardly into the brewing holster compartment of the beverage brewer B. In that regard, the body 226 includes first and second opposing outlet probe receptacles 254 and 258 extending upwardly from the bottom surface 242 of the body 226 and inwardly from the sidewall 228.

Each outlet probe receptacle 254 and 258 is of a sufficient depth and width to receive the outlet probe O so that the beverage brewing device 220 may be fully received within the brewing holster H. Moreover, the interior wall of the receptacles 254 and 258 fluidly isolates the outlet probe O from the brew chamber 236 when the outlet probe O is received within one of the first and second outlet probe receptacles 254 or 258.

The first and second outlet probe receptacles 254 and 258 are defined within opposite sides of the bottom surface 242 of the body 226 such that the beverage brewer 220 may be configured in one of two positions to seat within the brewing holster H (i.e., with one of the first and second opposing outlet probe receptacles 254 and 258 receiving the outlet probe O). It should be appreciated that the body 226 may instead include only one outlet probe receptacle such that the beverage brewer 220 is positionable in only one position within the brewing holster H. As yet another alternative, three or more outlet probe receptacles may instead be formed within the body 226 such that the beverage brewer 220 may be configured in three or more positions within the brewing holster.

It can be appreciated that however many number of outlet probe receptacles used (e.g., one, two, three, etc.) the remaining portion of the bottom surface 242 defines a flat surface upon winch the beverage brewing device 220 may rest when being filled with a dry beverage medium. In that regard, the beverage brewing device 220 may optimally include only two outlet probe receptacles 254 and 258 to ensure the bottom surface 242 is sufficiently large for resting on a surface and supporting the beverage brewing device 220 in an upright position during the fill process.

Moreover, by including no more than, for instance, two outlet probe receptacles 254 and 258, the body 226 can effectively have a deeper, larger interior brew chamber capacity. A larger brew chamber 236, as can be appreciated by one of ordinary skill in the art, can hold more dry beverage medium, such as coffee grounds, and can help create more turbulence during brewing for a more uniform, more efficient, and more thorough beverage extraction. The increased internal volume of the brew chamber 236 therefore accommodates consumers that prefer a stronger brew or more ounces of brewed coffee.

The body 326 is also formed such that its interior surface, including the surface defined by the outlet probe receptacles 254 and 258, has substantially rounded edges. As a result, the interior surface of the body 226 includes no hard-edged transitions and no crevices or corners where coffee grounds or other dry beverage mediums can get stuck. This helps ensure an easier cleanup for the consumer after the use of the beverage brewing device 220. In this manner, after each use, the beverage brewing device 220 may be quickly cleaned and reused for brewing another beverage.

To help align the beverage brewing device 220 within the brewing holster H such that the one of the first and second opposing outlet probe receptacles 254 and 258 receives the outlet probe O, the beverage brewing device 220 may include first and second opposing grips 262 and 266 that are receivable within correspondingly shaped cavities R (only one cavity R shown in hidden lines in FIG. 1 for clarity) in the brewing holster H when the beverage brewer 220 is disposed in the brewing position.

The first and second grips 262 and 266 are also graspable by a user for helping to insert and remove the beverage brewing device 20 from within the brewing holster H. In that regard, the first and second grips 262 and 266 may be coated with or otherwise formed with a heat-resistance, non-slip material, such as rubber. Other aspects of the first and second grips 262 and 266 are substantially similar to first and second grips 62 and 66 described above; and therefore, the first and second grips 262 and 266 will not be further described in detail.

Before positioning the body 226 within the brewing holster H for brewing a beverage, the brewing chamber 236 is first enclosed by the removable lid 284. The lid 284 is sized and configured on an exterior side to mate the inlet probe I of the beverage brewer B when the beverage brewing device 220 is received within a brewing holster H. (See FIG. 5). Moreover, the lid 284 is sized and configured on an interior side to seal within the top opening defined by the body 226 and distribute water received from the inlet probe I for brewing. (See FIG. 6).

The lid 284 is substantially similar to the lid 84 described above. In other words, the exterior side of the lid 84 is suitable for mating with the inlet probe I of a beverage brewer B and distributing the water from the inlet probe I into the brew chamber 36 of the beverage brewing device 220 for brewing a beverage. The lid 284 includes a lid body 286 having a substantially flat upper surface suitable to mate with a flat portion of an inlet probe assembly of the beverage brewer B (see FIG. 7).

A dispersion cone opening 288 is defined in substantially the center of the lid body 286 that opens into a dispersion cone 224. The dispersion cone opening 288 is in fluid communication with a receptacle 290 formed within the lid body 286. A receptacle plug 292 is disposed within the receptacle 290 to define an inlet probe opening 206 that in fluid communication with the dispersion cone 224. However, the lid 284 differs from lid 84 in that the elastomeric receptacle plug 292 is overmolded within the receptacle 290 rather than being removably received therein.

The receptacle plug 292 is overmolded within the receptacle 290 of the lid 284 in a manner well known in the industry. For instance, a primer or adhesive may first be applied to the surface of the lid 284 before the receptacle plug 292 is overmolded onto the lid 284. In the depicted embodiment, the lid 284 includes a plurality of mechanical protrusions 294 formed within the bottom interior surface of the receptacle 290. The mechanical protrusions 294 protrude upwardly from the bottom of the receptacle 290 to mechanical interlock with the overmolded receptacle plug 292. Similarly, an annular protrusion 298 is defined within the dispersion cone opening 288 to interlock with the overmolded receptacle plug 292.

When disposed within the receptacle 290, the receptacle plug 292 is sized and configured sealingly engage the inlet probe I or its surrounding inlet probe assembly, similar to receptacle plug 92 described above. By overmolding the receptacle plug 292 within the receptacle 290 of the lid 284, the receptacle plug 292 may be formed from an elastomeric, sealing material. However, the receptacle plug 292 is securely formed within the metal receptacle 290 of the lid 284. Thus, overmolding provides the flexibility of using multiple materials in a one piece design.

Referring to FIGS. 5 and 6, the interior side of the lid 284 suitable for enclosing the brew chamber 236 within the body 226 and for distributing water received from the inlet probe I for brewing will now be described. The interior side of the lid 284 is substantially similar to lid 84 described above. In that regard, the lid 284 includes a circular or annular protrusion 214 concentrically formed on the interior surface of the lid 284 that is sized and shaped to seat within the top opening defined by the body 220 of the beverage brewing device 220. An annular seal 216 is disposed within an annular recess extending around the annular protrusion 214 for mating with the top open end of the body 226 and forming a water-tight seal therebetween.

The lid 284 is hingedly secured to the body 236 such that the lid 284 may be moved between open and closed positions, substantially similar to lid 284 described above. Although any suitable hinge may be used, in the depicted embodiment, a piano hinge 220 is defined between the lid both 286 and a flanged rim 222 formed substantially transversely around the top open end of the body 220.

When the lid 284 is in the closed position, as shown in FIG. 7, the inlet probe I is positioned to extend through the inlet probe opening 206 in the receptacle plug 292 to release water into the dispersion cone 224, which is configured to help distribute water released from the inlet probe I. The dispersion cone 224 is substantially identical in structure and operation to the dispersion cone 124 described above; and therefore, it will not be further described.

In reference to FIGS. 5-7, the manner in which the beverage brewing device 220 may be used will now be described. Upon selecting a dry beverage medium to be brewed, such as coffee grounds, tea, etc., the beverage brewing device 220 may be set on a counter or other device such that the lid 284 may be moved into the open position. The lid 284 is moved about the axis defined by the hinge 220 into the open position, and the brew chamber 236 is filled with a desired mount of dry beverage medium, such as coffee grounds. For the strongest brew, the brew chamber 236 may be filled up to a fill line (not shown) near the upper open end of the brew chamber 236 such that the coffee grounds will be tamped by the dispersion cone 224 when the lid 284 is closed.

With the coffee grounds or another dry beverage medium added to the brew chamber 236, the lid 284 may be moved into the closed position, as shown in FIG. 7. With the lid 284 in the closed position, the annular protrusion 214 is received within the open top end 230 of the body 226, and the annular seal 216 is sealed against the interior surface of the body 226. Moreover, if the coffee grounds have been filled up to a fill line, the dispersion cone 224, upon closing the lid 284, will tamp the coffee grounds within the brew chamber 236.

With the coffee grounds or other dry beverage medium disposed within the beverage brewing device 220, the beverage brewing device 220 may be inserted into the beverage brewer B for brewing a beverage. In that regard, the beverage brewing device 220 is disposed within a brewing holster H of a beverage brewer B such that the first and second grips 262 and 266 are received within correspondingly shaped cavities R in the brewing holster H. With each of the first and second grips 262 and 266 received within a correspondingly shaped curved cavity R of the brewing holster H, the beverage brewing device 220 is aligned within the brewing holster H such that one of the first and second opposing outlet probe receptacles 254 and 258 in the beverage brewing device 220 receives an outlet probe O of the beverage brewer B.

With the beverage brewing device 220 received within the brewing holster H, the inlet probe assembly is lowered into engagement with the beverage brewing device 220, either manually or automatically (depending on the configuration of the beverage brewer B). The inlet probe assembly is lowered until the inlet probe abuts against the receptacle plug 292 and the inlet probe I is disposed within the inlet probe openings 206, as shown in FIG. 7.

With the inlet probe I in the brewing position, a beverage may be brewed according to the beverage brewer instructions. As can be appreciated by one of ordinary skill, to brew a beverage, the beverage brewer B dispenses heated water through the inlet probe I, which passes through the inlet probe opening 206 of the receptacle plug 292 and into the dispersion cone 224. The heated water, which becomes at least somewhat pressurized within the dispersion cone 224, passes through the openings in the dispersion cone 224 to substantially evenly and uniformly soak the coffee grounds within the brew chamber 236. The brewed beverage passes through the coffee grounds and out of the openings in filter areas 240, 244, 248, and/or 250 in the beverage brewing device 220 and into a C or other container positioned below the brewing bolster H in the beverage brewer B.

While illustrative embodiments have been illustrated and described, it will be appreciated that various changes can be made therein without departing from the spirit and scope of the invention.
