Many single serve beverage brewers have entered the market. Traditional brewers typically produce between four and twenty cups of beverage at a time. The beverage sits on a hot plate until it is consumed. As time passes, the taste of the beverage may decline. Single serve brewing allows a consumer to enjoy beverages, such as coffee and tea, in an efficient fashion and without a decline in the taste profile of the beverage.
- In
FIG. 1 , coffee or tea grounds for use in a single serving brewer may be packaged in a disposable singleuse beverage package 100. A disposable singleuse beverage package 100 may include abasket 110, which may be a permeable basket andbarrier 112, which may be a disposable impermeable barrier. - The
barrier 112 may have afirst side 114 and asecond side 116. Thefirst side 114 may include a score, a tab, a zip, an embedded string, or otherwise provide a means for assisting a user to open thebarrier 112. Thebarrier 112 may be sealed at thesecond side 116 or other sides by gusseting, pinching, heat sealing, stapling, or otherwise. Alternatively or additionally, thebarrier 112 may be a shrink wrap barrier or a wax barrier, among others. - The
barrier 112 may be substantially resistant to the passage of liquids, gases, and solids. For example, thebarrier 112 may be hermetically sealed to block moisture and oxygen from entering the pouch and to retain the aroma of the coffee. Additionally or alternatively, several baskets may be prefilled and packaged together in an egg crate type configuration, a tube, or other packaging, to maintain freshness during shipping and storing. Thebarrier 112 may be made of materials such as foil laminate, metalized films, EVOH films, polyolefin based material, parafilm, plastics, and combinations of these, among others. - A user may open the
package 100, for example, by tearing thebarrier 112 along thefirst side 114 to reveal thebasket 110. The user may remove thebasket 110 from thebarrier 112 and place thebasket 110 into a single serve brewer. Thebasket 110 may be prefilled with grounds, or alternatively, the user may add grounds to thebasket 110. - The
basket 110 may be a single-wall permeable basket including afirst end 118, which may be reversibly closed or an open end, and asecond end 120, which may be a closed end. Thebasket 110 may be a cup shaped basket and may be used with alid 122. Thebasket 110 may also have aside wall 124 and arim 126. Theside wall 124 may connect thesecond end 120 and therim 126. Theside wall 124 may include aframe 128 and afilter medium 130. - The
frame 128 may provide structure, stability, and integrity to thefilter medium 130. Theframe 128 may be formed by injection molding or by a different process suitable for manufacturing a rigid form around a relatively flexible filter medium. Theframe 128 may be made of any one of many commercially available materials, such as polystyrene, polyethylene, polypropylene, polyester, polyamide or Nylon, or other synthetic or natural plastics or combinations thereof. The frame may be made from other materials such as a bio-based polymer, such as polylacticacid (PLA), poly hydroxybutaric acid (PHA) or a starch based polymer. Theframe 128 may be made of other materials known to those skilled in the art. - In
FIG. 2 , theside walls 124 of thebasket 110 may be defined by theframe 128 and afilter medium 130. Thefilter medium 130 may be secured to thebasket 110, for example, at thesecond end 120, therim 126, and/or at thatframe 128. Thefilter medium 130 may be secured for example, by thermal bonding of the plastic used for theframe 128, or with an adhesive, by crimping, by heat sealing, or any other way. Thefilter medium 130 may be secured in theframe 128 in insert-injection molding of the plastic frame around a filter medium insert. For example, a pre-die cut blank of filter medium may be placed on a mandrel which has channels around the shape of the pre die-cut blank. Molten plastic may flow in and bond to the blank of thefilter medium 130 during inert-injection molding. The plastic may solidify into theframe 128, for example, upon cooling. Referring toFIGS. 7A-7C , in an alternative embodiment thefilter medium portion 700 and an optional bottom circular filter medium 705 herein after referred to as thecircular portion 705. Thefilter medium basket 710 with thefilter media basket 710. Thebottom end 715 of the frame of thebasket 710 may be substantially open and acircular filter portion 705 may cover the open portions. - The
filter medium 130 may be a porous material and may be permeable to liquids and some oils. It may be formed of many materials, for example, non-woven materials such as polystyrene, polyethylene, polypropylene, polylactic acid, cellulosic fibers, polyhydroxyalkanoates, thermoplastic starch, filter paper, other paper materials, polymer materials, a combination of these or any other material. Thefilter medium 130 may also be formed from a polymer or plastic filtration mesh, or microporous or apertured films made of various plastic materials, such as polypropylene, Nylon 6 and high density polyethylene or other materials known to those skilled in the art. Alternatively, thefilter medium 130 may be formed from a bio-based polymer, such as polylactic acid (PLA), poly hydroxybutaric acid (PHA) or starch based polymer. - Characteristics of the
filter medium 130 may be selected to meet the filtration needs of different products, such as ground coffee, tea powders or leaves, or other brewed products. For example, the basis weight, thickness, strand count, mesh size, flow rate and strength of thefilter medium 130 may be selected based on the product to be brewed. - The
filter medium 130 may be compostable, biodegradable, recycled, and/or recyclable. If thefilter medium 130 is a non-woven material, it may have a greater resistance than, for example, a woven material or a metal filter. Anon-woven filter medium 130 may retain water in the basket for longer than, for example, a woven or metal filter. The length of time that the water is retained in the basket with the grounds may influence the strength and therefore the taste profile of the resulting beverage. This may be because a woven material or a metal material may have technological limitations on the size of the openings there through. A non-woven material may not have the same technological limitations. Therefore, the difference may be that, in a woven material or metal material, the path of the water may be straight through the wall and in the non-woven material, the path may be indirect and convoluted. - The
basket 110 may include alid 122. Thelid 122 may include arim 202 and acover 200. Thecover 200 may be disposed below therim 202 for secure fitting with thebasket 110. Alternatively, thecover 200 may not include arim 202. Thecover 200 may be made from a material that may be punctured to allow a liquid to enter into the basket. For example, thecover 200 may be a material, such as a foil, film, coated film, or multilayer laminate, which is sealed to or across therim 126 of thepermeable basket 110 to maintain contents therein. Thecover 200 may keep dry contents dry, wet contents wet, and may maintain a freshness of the contents. Thecover 200 may be formed of a plastic, metallic foil, filter material, thermoplastic starch, or a laminate or composite thereof. - The
basket 110 may be dimensioned for use with a commercial single serve coffee brewer.FIG. 3 shows anexemplary basket 110. Thebasket 110 may have width of theopen end 312, and aheight 316. Theopen end 312 may be, for example but not limited to, about 38-42 mm. Theheight 316 may be, for example but not limited to, 38-42 mm. Therim 126 may have adimension 314 of, for example but not limited to, 3.5-5.5 mm. Theframe 128 may have adimension 320 of, for example but not limited to, 5 mm, and adimension 318 of, for example but not limited to 2 mm. These dimensions are merely exemplary and not limiting. Thebasket 110 may also have other dimensions or shapes, for example, dimensions that permit use in various single serve beverage machines. - In
FIG. 4 , abasket 110 may be prefilled withbeverage grounds 414, for example but not limited to, coffee or tea grounds. Alternatively or additionally, thebasket 110 may be loaded withbeverage grounds 414 immediately prior to use. If thebasket 110 is prefilled withbeverage grounds 414 it may be sealed with alid 122. Alternatively, if thepermeable basket 110 is not preloaded withbeverage grounds 414, it may not have alid 122, additionally or alternatively; it may have aremovable lid 122, or otherwise. - During use, a user may open the
barrier 112, take out thebasket 110 and place thebasket 110 into a single serve beverage machine. Aheated liquid 410 may be received by thebasket 110 through an opening in thecover 200 or otherwise. For example, during use, apreloaded basket 110 may be placed inside acartridge 400 for a single serve beverage machine. Thecartridge 400 may be reusable or disposable. During a brewing cycle, thecover 200 may be pierced by aprobe 416 to admitheated liquid 410 into thebasket 110. The heated liquid may interact with thebeverage grounds 414 creating a beverage medium. Thebeverage medium 418 may flow through thefilter medium 130 and exit through an opening in thecartridge 400. - As a second example, during use, an unloaded
permeable basket 110 may be placed inside acartridge 400 for a single serve beverage machine. Thecartridge 400 may be reusable or disposable. Thebeverage grounds 414 may be placed into thebasket 110. Acover 200 may be attached to maintain the contents of thebasket 110. During a brewing cycle, thecover 200 may be pierced by aprobe 416 to admitheated liquid 410 into thebasket 110. The heated liquid may interact with thebeverage grounds 414 creating a beverage medium. Thebeverage medium 414 may flow through thefilter medium 130 and exit through an opening in thecartridge 400. Alternatively, nocover 200 may be required. In this case, theheated liquid 410 will flow directly into thebasket 110. -
FIG. 5 illustrates one example of alid 122 for abasket 110. Thecover 200 of thelid 122 may include anopening 500 for entry of a liquid probe. Theopening 500 may be a weakened portion of the material of thecover 200 which may give easily under the pressure of a probe. - In
FIG. 6 , unloadedtapered baskets 110 may be configured for efficient nesting. Thebaskets 110 may be sold nested in a stack or tube, which may be packed in a sleeve of plastic film, or otherwise. Theunloaded basket 110 may allow the end user to select a variety ofbeverage grounds 414 for use in their single serve brewer. The end user may also be able to modify the amount ofbeverage grounds 414 for use in their single serve brewer. - The components of the single
use beverage package 100 may be selected with the intention of creating an environmentally friendly product. For example, thefilter medium 130 may be made from a range of synthetic or biodegradable, recycled or recyclable, or compostable materials such as polyolefins, polylacticacid, cellulosics, polyhydroxyalkanoates, thermoplastic starch, a combination of these or other materials. Thebasket frame 128 material,cover 200 andbarrier 112 may also be made out of these materials or similar synthetic, biodegradable, recycled or recyclable, or compostable materials which retain the properties of structural integrity (e.g., frame 128) and impermeability (e.g., barrier 112). - While various embodiments of the embodiments have been described, it will be apparent to those of ordinary skill in the art that many more embodiments and implementations are possible that are within the scope of the claims. For example, referring to
FIGS. 8A-8C ,logos 805 of various configurations may be placed on the lid 122 (FIG. 9A ), the basket 110 (FIG. 8B ), or the underside of thebasket 110. Thelogos 805 may also be printed on thefilter medium 130. Thelogos 805 enable a vendor to, for example, place descriptive information about the product that is in the basket, such as whether the product is coffee or tea, a type of blend, and the like. Other information known to those skilled in the art may also be printed. -
FIGS. 9A and 9B illustrate yet other embodiments of disposable beverage baskets.FIG. 9A andFIG. 9B illustrate beverage basket embodiments configured to control the positioning of the basket within a cartridge or brewer. Referring toFIG. 9A , the beverage basket 900 (shown upside down) includes aframe 128 andfilter material 903. Theframe 128 includes arim 126, abottom portion 120, and a group ofribs 906. Therim 126 defines an opening that corresponds to the top of theframe 128 when theframe 128 is in an upright position. Therim 126 may be continuous and have a circular shape, oval shape, or a different shape. Thebottom portion 120 is a closed surface that corresponds to the bottom of theframe 128. Theribs 906 extend from therim 126 to the edge of thebottom portion 120. Theribs 906,rim 126, andbottom portion 120 define a group of openings that facilitate fluid flow, such as coffee, tea, or a different beverage. - The
bottom portion 120 defines agroove 905 and/or an indentation 907 (SeeFIG. 9B ). Thegroove 905 may extend in a continuous manner along and inward of the edge of thebottom portion 120. Thegroove 905 and/orindentation 907 are configured to cooperate with a complementary feature, e.g., a protruded needle in the bottom of a cartridge or brewer to accurately position thebasket 900 within the cartridge or brewer. That is thegroove 905 and/orindentation 907 are configured to mesh with a complementary feature of the cartridge or brewer to control alignment of thebasket 900 so that the outer walls of thebasket 900 are not up against inner walls of the cartridge or brewer during use, which could otherwise limit fluid flow through thebasket 900. -
FIG. 10A andFIG. 10B , illustrateexemplary cartridges FIG. 10A , the feature corresponds to anannular ring 1005. Theannular ring 1005 may be suspended within the cartridge by one ormore bridge members 1007 to facilitate fluid flow around theannular ring 1005. Theannular ring 1005 may be sized to fit within thegroove 905 of thebeverage basket 900. In a brewer implementation, theannular ring 1007 may be formed in a portion of the brewer configured to receive thebeverage basket 900. In other implementations, theannular ring 1005 and one ormore bridge members 1007 may correspond to a separate component configured to fit substantially near the bottom of thecartridge 1000 or brewer and to maintain a distance between sidewalls of thecartridge 1000 or brewer. - Referring to
FIG. 10B , the feature corresponds to abutton 1017. Thebutton 1017 may be sized to fit within theindentation 907, described above. Thebutton 1017 may be supported by abridge member 1019 to enable fluid flow around thebutton 1017. In a brewer implementation, thebutton 1017 may be formed in a portion of the brewer configured to receive thebeverage basket 900. In other implementations, thebutton 1017 andbridge member 1019 may correspond to a separate component configured to fit substantially near the bottom of thecartridge 1015 or brewer and to maintain a distance between sidewalls of thecartridge 1015 or brewer. -
FIG. 11A andFIG. 11B illustratebeverage basket embodiments FIG. 11A , thebeverage basket 1100 includes aframe 128 andfilter material 903, as described above. For example, the frame includes arim 126, abottom portion 120, and a group ofribs 906. Therim 126 defines an opening that corresponds to the top a top of theframe 128. Therim 126 may be continuous and have a circular shape, oval shape, or a different shape. Thebottom portion 120 is a closed surface that corresponds to the bottom of theframe 128. Theribs 906 extend from therim 126 to the edge of thebottom portion 120. Theribs 906,rim 126, andbottom portion 120 define a group of openings that facilitate fluid flow, such as coffee, tea, or a different beverage. - Each
rib 906 includes aledge 1105 and 1110 (FIG. 11B ) positioned in a center region. Theledges respective baskets FIG. 12B ) betweenrespective bottoms 120 of thebaskets space 1210 may be sized to facilitate storage of beverage grounds, such as coffee ground, tea grounds, or other grounds, which thebaskets ledges ribs 906 may be configured to result in a desired amount ofspace 1210 between respective baskets. Thus, several baskets may be advantageously filled with grounds and then stacked to save space. - In some configurations, the
ledge 1105 extends outwardly away from the center of the basket. (SeeFIG. 11A ). Referring toFIG. 12A , in this configuration, theledge 1105 of atop basket 1205 rests upon therim 126 of alower basket 1207. In this regard, the distance between opposing ledges 1105 (i.e.,ledges 1105 on opposite sides of the basket 1100) may be equal to about the inner diameter of therim 126. - In other configurations, the
ledge 1110 extends inwardly towards the center of the basket. (SeeFIG. 11 B). Referring toFIG. 12B , in this configuration, thebottom portion 120 of thetop basket 1205 rests upon theledge 1110 of thelower basket 1207. In this regard, the distance between opposing ledges 1110 (i.e.,ledges 1105 on opposite sides of the basket 1100) may be equal to about the outer diameter of thebottom portion 120. -
FIGS. 13A-13C illustrate perspective, side, and bottom views, respectively, of yet anotherbeverage basket embodiment 1300. Thebeverage basket 1300 is configured to be placed into a brewer (not shown) without the need for acartridge 400. Such brewers typically include a receiving member sized to receive a basket with a similar although not identical shape. A protruded membrane-piercing needle is positioned in the lower portion of the receiving member and is configured to pierce the lower portion of a typical plastic cup (e.g., a generally cylindrically shaped cup with a flat and closed bottom surface) so as to facilitate fluid flow out of the basket, through the needle, and then into a cup. - The
beverage basket embodiment 1300 includes aframe 1305. Theframe 1305 includes arim 1310, abottom portion 1315, and a group ofribs 1320. Therim 1310 defines an opening that corresponds to the top of theframe 1305 when theframe 1305 is in an upright position. Therim 1310 may be continuous and have a circular shape, oval shape, or a different shape. Thebottom portion 1315 is a closed surface that corresponds to the bottom of theframe 1305. Theribs 1320 extend from therim 1310 to the edge of thebottom portion 1315. Theribs 1320,rim 1310, andbottom portion 1315 define a group of openings that facilitate fluid flow, such as coffee, tea, or a different beverage. Thebeverage basket embodiment 1300 also includes a filter material that covers the openings, such as any of the filter materials described above, which is not shown in this instance for clarity. - A first portion 1325 (
FIG. 13C ) of thebottom portion 1315 is substantially flat. Whereas asecond portion 1330 of thebottom portion 1315 defines anindentation 1335, which can be either fully enclosed or semi enclosed. Thefirst portion 1325 may occupy % or more of the surface area of thebottom portion 1315. Thesecond portion 1330 may occupy the remaining area. Theindentation 1335 is sized so that when thebasket 1300 is inserted into the receiving member, the membrane-piercing needle fits within theindentation 1335 and does not pierce thebottom portion 1315. For example, a depth D of theindentation 1335 relative to the lower surface offirst portion 1325 of the bottom surface may be, for example but not limited to, about .388 inches. The width of theindentation 1330 may be, for example but not limited to, about 0.287 inches, and theindentation 1335 may be offset towards a side edge of thebottom portion 1315, which corresponds to the location of the membrane-piercing needle in some brewer implementations. However, theindentation 1335 may be located in a different location when the membrane-piercing needle is positioned differently. Limiting the space occupied by the indentation 1335 (i.e., maximizing the space occupied by the first portion) results in more space within thebasket 1300 for grounds, such as coffee grounds. This in turn facilitates the production of stronger blends. -
FIGS. 14A-16B illustrate various exemplary lids for covering thebeverage basket embodiment 1300. The respective lids are configured to selectively substantially seal the opening defined at the top of theframe 1305.FIGS. 14A and 14B illustrate a firstexemplary lid 1400. Thelid 1400 includes anopening 1402 in a center region through which a liquid flows into thebasket 1300. Thelid 1400 also includes anannular ring 1405 configured to be friction fit against an inner surface of therim 1310 of theframe 1305 to thereby form a seal between thelid 1400 and thebeverage basket 1300. That is, a seal between the outer surface of theannular ring 1405 and the inner surface of therim 1310. The diameter of theannular ring 1405 may be sized to provide a tight fit between thelid 1400 and thebasket 1300 while still facilitating removal of thelid 1400. -
FIGS. 15A and 18 illustrate a secondexemplary lid 1500. Thelid 1500 includes anopening 1502 in a center region through which a liquid flows into thebasket 1300. Thelid 1500 includes asidewall 1505 configured to be snap fit over an outer edge of therim 1310. In other words, the seal between thelid 1500 and thebeverage basket 1300 is formed between the inner surface of thesidewall 1505 and the outer surface of therim 1310. The diameter of thesidewall 1505 may be sized to provide a tight fit between thelid 1500 and thebasket 1300 while still facilitating removal of thelid 1500. -
FIGS. 16A and 16B illustrate anotherexemplary beverage basket 1600 andlid 1610. Thebeverage basket 1600 includes the features of thebeverage basket 1300 described above. However, therim 1605 defines one ormore cutouts 1612. Thelid 1610 includes one ormore tracks 1615 configured to cooperate with the one ormore cutouts 1612 to facilitate twist locking of thelid 1610 to thebeverage basket 1600. In this regard, the thickness of therim 1605 may gradually increase with a distance away from thecutouts 1612 so that the tightness between thelid 1610 and thebeverage basket 1600 increases with further twisting of thelid 1610. - The configurations above may be varied. For example, as illustrated in
FIG. 17 , thebasket 1700 andlid 1705 shown inFIG. 14 may be formed together so that in an open configuration thelid 1705 is attached to thebasket 1700. Thelid 1705 may then be folded over thebasket 1700 to close the top opening of thebasket 1700 defined by therim 1710. Acutout 1715 may be formed in therim 1710 to expose an underside of thelid 1705 when thelid 1400 is in the closed configuration. Thecutout 1715 facilitates removal of thelid 1705 from thebasket 1700. - As illustrated in
FIGS. 18A and 18B ,liquid distribution fins 1810 may be formed on the underside of thelid 1805. During operation, liquid flowing into the lid opening will, through capillary pressure, be drawn over theliquid distribution fins 1810 and then drop onto the grounds in thebasket 1800. Theliquid distribution fins 1810 distribute the liquid over a larger portion of the grounds in thebasket 1800 than would occur without the use offins 1810. This in turn facilitates more even brewing of the beverage. It is understood that the shape and number offins 1810 are only exemplary. - Accordingly, it will be apparent to those of ordinary skill in the art that many more embodiments and implementations are possible that are within the scope of the claims. Therefore, the embodiments described are only provided to aid in understanding the claims and do not limit the scope of the claims.
