DETAILED DESCRIPTION OF THE INVENTION
(27) Single serve beverage brewing is popular among consumers due to the convenience and flexibility that it provides. 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.
(28) In
(29) The barrier 112 may have a first side 114 and a second side 116. The first side 114 may include a score, a tab, a zip, an embedded string, or otherwise provide a means for assisting a user to open the barrier 112. The barrier 112 may be sealed at the second side 116 or other sides by gusseting, pinching, heat sealing, stapling, or otherwise. Alternatively or additionally, the barrier 112 may be a shrink wrap barrier or a wax barrier, among others.
(30) The barrier 112 may be substantially resistant to the passage of liquids, gases, and solids. For example, the barrier 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. The barrier 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.
(31) A user may open the package 100, for example, by tearing the barrier 112 along the first side 114 to reveal the basket 110. The user may remove the basket 110 from the barrier 112 and place the basket 110 into a single serve brewer. The basket 110 may be prefilled with grounds, or alternatively, the user may add grounds to the basket 110.
(32) The basket 110 may be a single-wall permeable basket including a first end 118, which may be reversibly closed or an open end, and a second end 120, which may be a closed end. The basket 110 may be a cup shaped basket and may be used with a lid 122. The basket 110 may also have a side wall 124 and a rim 126. The side wall 124 may connect the second end 120 and the rim 126. The side wall 124 may include a frame 128 and a filter medium 130.
(33) The frame 128 may provide structure, stability, and integrity to the filter medium 130. The frame 128 may be formed by injection molding or by a different process suitable for manufacturing a rigid form around a relatively flexible filter medium. The frame 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 polylaticacid (PLA), poly hydroxybutaric acid (PHA) or a starch based polymer. The frame 128 may be made of other materials known to those skilled in the art.
(34) In
(35) 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. The filter 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, the filter medium 130 may be formed from a bio-based polymer, such as polylatic acid (PLA), poly hydroxybutaric acid (PHA) or starch based polymer.
(36) 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 the filter medium 130 may be selected based on the product to be brewed.
(37) The filter medium 130 may be compostable, biodegradable, recycled, and/or recyclable. If the filter medium 130 is a non-woven material, it may have a greater resistance than, for example, a woven material or a metal filter. A non-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.
(38) The basket 110 may include a lid 122. The lid 122 may include a rim 202 and a cover 200. The cover 200 may be disposed below the rim 202 for secure fitting with the basket 110. Alternatively, the cover 200 may not include a rim 202. The cover 200 may be made from a material that may be punctured to allow a liquid to enter into the basket. For example, the cover 200 may be a material, such as a foil, film, coated film, or multilayer laminate, which is sealed to or across the rim 126 of the permeable basket 110 to maintain contents therein. The cover 200 may keep dry contents dry, wet contents wet, and may maintain a freshness of the contents. The cover 200 may be formed of a plastic, metallic foil, filter material, thermoplastic starch, or a laminate or composite thereof.
(39) The basket 110 may be dimensioned for use with a commercial single serve coffee brewer.
(40) In
(41) During use, a user may open the barrier 112, take out the basket 110 and place the basket 110 into a single serve beverage machine. A heated liquid 410 may be received by the basket 110 through an opening in the cover 200 or otherwise. For example, during use, a preloaded basket 110 may be placed inside a cartridge 400 for a single serve beverage machine. The cartridge 400 may be reusable or disposable. During a brewing cycle, the cover 200 may be pierced by a probe 416 to admit heated liquid 410 into the basket 110. The heated liquid may interact with the beverage grounds 414 creating a beverage medium. The beverage medium 418 may flow through the filter medium 130 and exit through an opening in the cartridge 400.
(42) As a second example, during use, an unloaded permeable basket 110 may be placed inside a cartridge 400 for a single serve beverage machine. The cartridge 400 may be reusable or disposable. The beverage grounds 414 may be placed into the basket 110. A cover 200 may be attached to maintain the contents of the basket 110. During a brewing cycle, the cover 200 may be pierced by a probe 416 to admit heated liquid 410 into the basket 110. The heated liquid may interact with the beverage grounds 414 creating a beverage medium. The beverage medium 414 may flow through the filter medium 130 and exit through an opening in the cartridge 400. Alternatively, no cover 200 may be required. In this case, the heated liquid 410 will flow directly into the basket 110.
(43)
(44) In
(45) The components of the single use beverage package 100 may be selected with the intention of creating an environmentally friendly product. For example, the filter 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. The basket frame 128 material, cover 200 and barrier 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).
(46) 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

(56) The beverage basket embodiment 1300 includes a frame 1305. The frame 1305 includes a rim 1310, a bottom portion 1315, and a group of ribs 1320. The rim 1310 defines an opening that corresponds to the top of the frame 1305 when the frame 1305 is in an upright position. The rim 1310 may be continuous and have a circular shape, oval shape, or a different shape. The bottom portion 1315 is a closed surface that corresponds to the bottom of the frame 1305. The ribs 1320 extend from the rim 1310 to the edge of the bottom portion 1315. The ribs 1320, rim 1310, and bottom portion 1315 define a group of openings that facilitate fluid flow, such as coffee, tea, or a different beverage. The beverage 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.
