Definitions
- the present disclosure pertains generally to devices and methods related to single-serve beverage brewers, and more particularly to cellulose-based single-serve beverage cartridges.
- single-serve beverage brewers e.g., those made by Keurig Green Mountain, Inc., of Waterbury, VT and other manufacturers
- Single-serve beverage brewers with their corresponding specialized packages of coffee, tea, or other beverage materials, have become a significant segment of the beverage industry.
- Single-serve beverage brewers pump fluid from a reservoir to a heater tank for heating, and then deliver the heated fluid to a beverage formation chamber, such as a brew head.
- the beverage formation chamber may be configured to hold a single-serve beverage container, pod, or cartridge (also referred to as a "cartridge” or a “beverage cartridge” herein) containing a beverage medium, e.g., coffee grounds, tea leaves, cocoa mix, dried soup, etc., for mixing with the fluid to make a beverage.
- a beverage medium e.g., coffee grounds, tea leaves, cocoa mix, dried soup, etc.
- a beverage medium e.g., coffee grounds, tea leaves, cocoa mix, dried soup, etc.
- Single-serve brewers may employ specialized cartridges, e.g., cartridges with a particular shape, encoded with special characters or codes, etc., such that only certain cartridges may be employed in a particular brewer.
- the specialized package of coffee, tea, or other beverage materials used in single-serve brewers is most often a closed plastic cup with the beverage material inside, sealed with aluminum foil or other type of cover. Specialized inks are used to print on the plastic and/or aluminum foil to indicate the type of beverage material inside, lot numbers, etc.
- the cover is often attached to the plastic cup with an adhesive.
- the cartridges may include a filter inside the plastic cup to reduce and/or minimize the amount of beverage material (e.g., coffee grounds, tea leaves, etc.) that are transferred from the cartridge to a mug, cup, and/or other receptacle that a person would use for drinking the resultant beverage.
- beverage material e.g., coffee grounds, tea leaves, etc.
- the cartridges may also be pressurized with an inert gas, such as nitrogen or carbon dioxide, to reduce oxidation and/or other degradation of the beverage material prior to use in the single-serve brewer.
- heated fluid often water
- the cartridge must be able to withstand the operational temperatures and pressures that are present during brewing.
- Plastic is a polymer matrix; at single-serve brewer operational temperatures, portions (monomers) of the polymer chain disengage from the polymer matrix. These monomers are in direct contact with a heated liquid that leaches the monomers into the liquid, and thus may be delivered along with the liquid into a beverage. The consumer may then ingestings these chemicals, e.g., Bisphenol-A (BP A), other monomers, or other potentially hazardous substances, without being aware that they are doing so.
- BP A Bisphenol-A
- aspects of the present disclosure comprise methods and apparatuses for aiding in the recyclable and/or compostable nature of the materials present in single-serve beverage cartridges.
- Other aspects of the present disclosure comprise reducing health risks associated with current single-serve cartridges.
- a cartridge in accordance with an aspect of the present disclosure may comprise a cartridge body comprising a closed end having a first diameter and an open end opposite the closed end.
- the open end of the cartridge body comprise a rim, the rim having an outer diameter that is greater than the first diameter and further comprising an inner diameter that is less than the outer diameter.
- the cartridge body may consist essentially of home- compostable material, wherein the cartridge body is adapted to be received in a receptacle of a single-serve beverage brewer such that the closed end of the cartridge body is placed into the receptacle of the single-serve beverage brewer, wherein the closed end of the cartridge body is piercable by an outlet needle in the single-serve brewer.
- the cartridge further includes a home-compostable filter, coupled to the cartridge body proximate to the rim of the open end of the cartridge body, such that the filter extends below an upper edge of the open end of the cartridge body and extends into an interior of the cartridge body, the filter extending toward the closed end of the cartridge body such that at least a portion of the filter is proximate an interior surface of the cartridge body, wherein the filter is unpierced by the outlet needle in the single-serve brewer when the closed end of the cartridge body is pierced by the outlet needle in the single-serve brewer.
- the cartridge further comprises a beverage material, coupled to the filter, such that the beverage material extends below the upper edge of the open end of the cartridge body and extends into the cartridge body toward the closed end of the cartridge body.
- the cartridge further comprises a cover, coupled to the open end of the cartridge body, such that the cover encapsulates the beverage material within the interior of the cartridge body, the beverage material further being encapsulated between the filter and the cover, the cover consisting essentially of a home-compostable material and adapted to be pierced by a fluid delivery nozzle in the single-serve brewer.

- the present disclosure is directed toward single-serve cartridges that are able to withstand the operational conditions of single-serve brewing devices that are also more readily recycled than current cartridges.
- a single-serve cartridge in accordance with an aspect of the disclosure also may mitigate health risks associated with current cartridge materials.
- Embodiments of the disclosure are described herein with reference to cross- sectional view illustrations that are schematic illustrations of embodiments of the disclosure. As such, the actual dimensions of elements can be different, and variations from the shapes of the illustrations as a result, for example, of manufacturing techniques and/or tolerances are expected. Embodiments of the disclosure should not be construed as limited to the particular shapes of the regions illustrated herein but are to include deviations in shapes that result, for example, from manufacturing. A region illustrated or described as square or rectangular may have slightly rounded or curved features due to normal manufacturing tolerances. Thus, the regions illustrated in the figures are schematic in nature and their shapes are not intended to illustrate the precise shape of a region of a device and are not intended to limit the scope of the disclosure. It is understood that the shapes, sizes, and locations in the attached figures may not be to scale. Overview
- a single-serve cartridge in an aspect of the present disclosure may withstand broader operational characteristics, e.g., temperature, pressure, etc., than current cartridges. Such a cartridge may prevent and/or reduce blowouts and/or other over pressurization issues, which may increase clean-up efforts and endanger users.
- the present disclosure may mitigate the lack of sustainable design for single-serve beverage cartridge (e.g., K-cup®) materials and designs.
- An embodiment of the present disclosure seals the filter and the cover together, with the beverage material inbetween.
- This assembly may be removed from the external cup (also referred to as "container” herein) and the beverage material is then contained within the assembly.
- the external cup is then completely separated from the cover, filter, and beverage material, and could be recycled.
- the cover/filter/beverage material can be composted or discarded as desired.
- This aspect of the present disclosure allows the beverage material to be removed as a whole, and maintains the convenience of the single-serve cartridge design while introducing conservation and ecological sustainability into single-serve beverage systems.
- the external cup materials may be altered to reduce and/or eliminate leaching of monomers into the resultant beverage.
- Current external cup materials employ plastic materials for the external cup, which when exposed to operational temperatures of single-serve brewing systems will leach various undesirable materials into the beverage to be consumed.
- FIG. 1 is a schematic view of one embodiment of a beverage system according to an aspect of the present disclosure.
- system 100 includes pump 102 that can be configured to pump unheated fluid, e.g., water, from a reservoir 104 to a heater 106, which heats the water to a desired temperature for delivery to a brew head 108.
- the brew head 108 includes a receptacle 1 10 that can house a cartridge 1 12 containing a single-serve or a multi-serve amount of a beverage material 114, e.g., coffee grounds, tea, hot chocolate, lemonade, etc., for producing a beverage dispensed from the brew head 108.
- the beverage can be dispensed into a container 1 16, e.g., mug, carafe, etc. which can be placed on a platen 1 18.
- the reservoir 104 may store fluid 120, e.g., ambient temperature water, that may be used to brew a serving and/or multiple servings of beverage (e.g., coffee) in accordance with the embodiments and processes disclosed herein.
- the fluid 120 may exit the reservoir 104 during the brew process via an outlet 122 at the bottom of reservoir 104.
- the fluid 120 may exit the reservoir 104 from locations other than the bottom, such as the sides or the top such as via a reservoir 104 pickup extending down into the reservoir 104, or other locations as desired or feasible.
- the reservoir 104 includes a water level sensor 124 and/or other sensors (not shown) to detect whether the reservoir 104 is sealed by the lid, has a low water level, or other conditions, and may interact with brewer 100 circuitry to prevent initiation of a brew cycle in the event there are undesirable conditions present in brewer 100.
- the reservoir 104 may be replaced by other fluid 120 sources, such as a water tap connection.
- the pump 102 pressurizes and/or pumps fluid 120 from the reservoir 104 to the cartridge 1 12 and/or pumps air to purge remaining fluid 120 and/or brewed beverage from the beverage system 100.
- the pump 102 initially pumps fluid 120 from the reservoir 104 through a first conduit 126 to the heater tank 106 where the fluid 120 is heated to a predetermined temperature before delivery to the cartridge 1 12 to brew the beverage material 114 into beverage 128.
- the pump 102 pumps air through the beverage system 100 to purge any remaining fluid 120 or beverage 128 in brewing system 100.
- the pump 102 is able to operate in both wet and dry conditions, i.e., the pump 102 can switch between pumping water and air without undue wear and tear, although separate pumps for water and air are possible without departing from the scope of the present disclosure.
- each cartridge 112 provides resistance to the flow of fluid through cartridge 112 to mug 1 16. This resistance varies based on, among other things, the beverage medium within cartridge 1 12. For example, and not by way of limitation, bouillon within cartridge 112 may provide less resistance to fluid flow than ground coffee, because bouillon dissolves in the heated fluid 120 from nozzle 140 while coffee grounds do not.
- the pressure drop across the beverage material 1 14 can result in back pressure against the outlet of check valve 132. If this back pressure is high enough (e.g., equal to or greater than the difference in pressure between the inlet and outlet of the check valve 132), check valve 132 may close, or cartridge 112 (or filter paper that is internal to cartridge 1 12) may be "blown out” by the pressure created by the incoming pressure of the heated fluid through nozzle 140.
- FIG. 2 illustrates a beverage cartridge in accordance with an aspect of the present disclosure.
- Cartridge 1 12 comprises a cartridge body 200, a filter 202, and a cover 204.
- cartridge body 200 may comprise of a cellulose-based material.
- Filter 202 is inserted into cartridge body 200 and may be adhered to cartridge body 200 at ridge 206.
- Sides 208 of filter 202 may be pleated or otherwise shaped to fit within a shape of cartridge body 200.
- cartridge body 200 may be frustoconical in shape, and filter 202 may be pleated along the sides 208 such that the top of filter 202 sides 208 may be adhered to ridge 206 while sides 208 are proximate the frustoconical shape of the cartridge body 200.
- the shape and/or depth of filter 202 allows for a space 210 ("X") to reside between a bottom 212 of cartridge body 200 and bottom 214 of filter 202.
- Space 216 is the depth to which outlet needle 158 penetrates into cartridge body 200.
- Space 210 is often larger than space 216, to ensure that outlet needle 158 does not pierce filter 202, which would allow beverage material 1 14 to be delivered out of outlet needle 158 to mug 1 16 (as shown in FIG. 1).
- Cartridge body 200 may also be spherical, hemispherical, and/or any other shape without departing from the scope of the present disclosure.
- Cover 204 is adhered to rim 218 with adhesive 220.
- Adhesive 220, and adhesive 222 used to adhere filter 202 to cartridge body 200 may be a sonic welding adhesion, a compression, crimiping, and/or fusing of filter 202 to cartridge body 200, and/or an adhesive material, which couples cover 204 to cartridge body 200.
- Cover 204 provides a substantially air-tight seal such that beverage material 114 is not exposed to air, which may oxidize beverage material.
- cover 204 when adhered to cartridge body 200, may allow for an inert gas, such as nitrogen, to be contained within cartridge 112 to further reduce oxidation and/or other degradation of beverage material 1 14 between the time beverage material 1 14 is packaged in cartridge 112 and used in brewing system 100. Such a reduction in degradation of beverage material 1 14 may improve the flavor and/or consistency of beverage 128 produced in brewing system 100.
- an inert gas such as nitrogen
- Cartridge 122 and in particular cartridge body 200, is often made from plastic.
- Plastic materials may be categorized to by their "recycling number" which is often stamped or otherwise imprinted on plastic materials to indicate the type of plastic used in making a specific container. Depending on the recycling number, plastic materials may or may not be recyclable.
- Plastic #1 Polyethylene Terephthalate (sometimes referred to as “PETE” or “PET”), is often clear or transparent and used to make soda and/or water bottles.
- Plastic #2 High Density Polyethylene, (sometimes referred to as “HDPE”) is often opaque, and may be used to manufacture milk jugs, household cleaner containers, juice bottles, shampoo bottles, and box liner bags.
- Plastic #3 vinyl (also known as polyvinylchloride, or referred to as “V” or “PVC”), may be used in food wrapping materials, plumbing pipes, and detergent bottles.
- Plastic #4 Low Density Polyethylene (sometimes referred to as "LDPE”) may be found in squeezable bottles, shopping bags, and/or food wrapping materials.
- LDPE Low Density Polyethylene
- Plastic #5 Polypropylene (also referred to as “PP” or “polypro”) may be used in making yogurt containers, and/or food packaging bottles.
- Plastic #6 Polystyrene (sometimes referred to as “PS” or “Styrofoam”) may be found in compact disc cases, egg cartons, meat trays, and/or disposable plates and cups.
- Plastic #7 is a "miscellaneous" category, where plastic resins or mixtures of plastic resins that do not fit into categories 1-6 are placed.
- Plastic #7 may include polycarbonates, and may be used to manufacture sunglasses, computer cases, nylon, and/or other goods.
- cartridge body 200 may be recyclable. Although all plastics are theoretically recyclable, many curbside recycling programs will not accept some plastics, e.g., plastic #6, plastic #7, etc., as recyclable materials.
- plastics may contain chemicals that may leach from the body 200 material under certain conditions.
- plastic #3 may contain Bis(2-ethylhexyl) adipate, or DEHA.
- DEHA has been demonstrated to induce liver adenomas and carcinomas in mice, and many people consider DEHA to be a human health risk.
- plastic #7 may contain bisphenol-A (BP A).
- BP A bisphenol-A
- BPA is also potentially toxic in humans, as BPA is considered to be a hormone disruptor linked to infertility, hyperactivity, reproductive problems, and other health issues.
- fluid 120 may be heated to 190 °F and introduced into cartridge 112 for several minutes at a lower pressure, e.g., 1 -5 pounds per square inch (psi), although the pressures can be higher or lower than those listed.
- psi pounds per square inch
- fluid 120 may be heated to approximately 210 °F and introduced into cartridge 112 for a shorter period of time at a higher pressure, e.g., 8-20 bar (100-280 pounds per square inch (psi)), although the pressures can be higher or lower than those listed.
- Some brewing processes may include fluid 120 temperatures above 212 °F when steam is injected through nozzle 140. These time, temperature, and pressure variables may also be user-selected. As such, cartridge 112, and thus cartridge body 200, may be exposed to a range of temperatures and pressures, and the range of temperatures and pressures may or may not be known prior to cartridge body 200 use.
- Cellulose-based materials that may be employed for the cartridge body 200 in an aspect of the present disclosure include, but are not limited to, recycled paper, paper, organic materials such as plants, etc., and other materials. Such materials may include binding material, such as starches, glue, etc., and/or materials that increase the ability of cartridge body to withstand the conditions of brewer 100.
- FIG. 3 illustrates a method for recycling a beverage cartridge as described in the related art.
- a process 300 for recycling K-cup® cartridges 112 (also known as "pods") is illustrated.
- Block 302 indicates that cover 204 should be peeled from cartridge body 200 after cartridge 112 has cooled.
- Cover 204 is grasped by the puncture (hole) in cover 204 made by inlet nozzle 140 and removed from cartridge body 200. Cover 204 is to be disposed after removal.
- beverage material 114 is to be emptied from cartridge body 200.
- Beverage material 1 14 may be composted or disposed of.
- Filter 202 (not shown in FIG. 3) is described as remaining in cartridge body 200.
- cartridge body 200 is described as being made from Plastic #5, which is polypropylene, and can be recycled once cover 204 is removed and beverage material 1 14 is emptied out of cartridge body 200.
- the related art as shown in FIG. 3 does not provide a time-effective and/or method for recycling cartridge body 200.
- the user must remove the cover 204 from a hole that is approximately 0.2 inches in diameter, which is inconvenient, and remove the beverage material 1 14 separately.
- the cover 204 is difficult to remove from the cartridge body 200 in a single piece, since the user will likely tear out a section of cover 204 from the puncture towards the edge of cover 204. Having to remove the beverage material 1 14 separately from the cover merely adds to the inconvenience of the related art method.
- the related art method does not address the decomposition of cartridge body 200 during the operational conditions of beverage system 100.
- Plastic #7 may deform from their original thermoplastically-set shape when exposed to fluid 120 at 205 °F.
- Plastic #5 which may have a higher melting point than plastic #7, still may leach materials into beverage 128.
- binders and/or fillers that may be included in plastic #5 when used in cartridge body 200, and how these binders and/or fillers may also be leached into beverage 128.
- thermosetting and thermoplastic materials do not often have a well-defined phase transformation at a specified temperature. Instead, thermoplastic and thermosetting materials have a second-order transition between solid and liquid phases.
- thermosetting and thermoplastic materials do not have a single transition curve.
- Polypropylene (Plastic #5) is 65% crystalline, and has a crystalline melting temperature of 170 degrees Centigrade. Because polypropylene is not 100% crystalline, it is considered as partially amorphous and, thus, is a fluid that, over periods of time, will flow into different shapes and has internal flow within the structure, even at room temperatures.
- This characteristic of polypropylene, and/or other thermosetting and thermoplastic materials is similar to window glass, as both materials are amorphous.
- the transition from a glass state to a soft and/or malleable state is called the glass-transition region, and begins occurring at a temperature known as the glass transition temperature.
- This property of thermoplastic materials is what allows these materials to be formed through the use of heat, and then cooled to the point where they are rigid and in the desired shape.
- the cartridge body 200 may begin as a flat sheet of plastic, but is formed into the frustoconical shape of the cartridge body 200 by addition of heat and/or pressure to form the shape of cartridge body 200.
- the "polypropylene" material may have a large number of transition curves and thus leach at different rates for a given temperature.
- polypropylene has internal fluidic migrations of materials, i.e., the 35% of material in polypropylene that is not crystalline, even though these migrations are not visible to the human eye.
- cartridge body 200 when cartridge body 200 is exposed to the operational conditions of brewing system 100, cartridge body 200 may be in direct contact with fluid 120 at temperatures between 145-212 °F for several minutes.
- the fluidic motion of the noncrystalline materials within cartridge body 200, as well as the crystalline polypropylene itself, and/or any fillers and/or binders used in cartridge body 200, would thus be raised even further above the glass transition temperature, and become fluid in the classical sense.
- the fluid 120 is also pressurized against the cartridge body 200, and the combination of pressure and temperature conditions present in brewing system 100 may create leaching of some of the cartridge body 200 material and/or the fillers and/or binders present in the cartridge body 200 material into beverage 128.
- FIG. 4 illustrates a cross-sectional view of a single-serve beverage cartridge in accordance with an aspect of the present disclosure.
- filter 202 may be attached to cover 204 by adhesive 400.
- Cover 204 may also be made of a cellulose-based material, and may be made of a different cellulose-based material than cartridge body 200 without departinf from the scope of the present disclosure.
- Portion 402 of filter 202 is then coupled to rim 218 of cartridge body 200, rather than being coupled to ridge 206. This may simplify the manufacture of cartridge 112, as filter 202 may be coupled to cover 204 prior to attachment of the then combined filter 202/cover 204 to cartridge body 200.
- beverage material 114 may be sandwiched in a pod comprising filter 202 and cover 204 (as well as other layers of material if desired), and these pods may then be coupled to rim 218 of cartridge body 200.
- a pod comprising filter 202 and cover 204 (as well as other layers of material if desired), and these pods may then be coupled to rim 218 of cartridge body 200.
- the attachment of filter 202 to cover 204 rather than to the ridge 206 of cartridge body 200 is not critical to the operation of cartridge 112 in beverage system 100.
- filter 202 is designed to hold beverage material 114 above the level of the needle 158 at all locations. If cartridges 112 were designed to be pierced on the cover 204 for both the inlet nozzle 140 and the outlet needle 158, filter 202 would have no such restriction for having a bottom 214 that sits a distance 210 away from bottom 212. Some cartridges that may be used for multi-serve brewing, such as K-carafe® cartridges, are designed to be pierced on the cover by a second needle for delivering the beverage 128 to mug 116 and are not pierced on the bottom by outlet needle 158.
- Such cartridges are not considered single-serve cartridges 112, and are not compatible with all brewing systems 100 in the single-serve brewing market. Further, such multi-serving and/or multi-serve cartridges have not been as well accepted in the marketplace as the single-serve cartridges 112 that are pierced on the bottom 212 of cartridge body 200, because the multi-serve cartridges are less convenient than the single-serve cartridges 112. However, such multi-serve cartridges are also considered to be "single-serve" cartridges 112 for the purposes of this disclosure.
- Adhesive 400 may be the same adhesive material as adhesive 220, or may be a different adhesive depending on the materials used in filter 202, cover 204, and cartridge body 200, and/or other considerations as desired.
- cover 204 may include tab 404, which extends beyond an outer circumference of rim 218 of cartridge body 200. Tab 404 provides a gripping surface for cover 204, such that cover 204 may be removed from rim 218, rather than attempting to pull cover 204 away from rim 218 via a pierced hole as described with respect to FIG. 3.
- cover 204 is now coupled to filter 202, pulling tab 404 may separate filter 202 and cover 404 from cartridge body 200 together, rather than leaving filter 202 in cartridge body 200 as described with respect to FIG. 3. Further, because filter 202 and cover 404 are coupled together, either via adhesive 400 and/or by other methods, beverage material 114 is contained within the combination of filter 202 and cover 204. In many beverage systems 100, beverage material 114 has been purged of most of the fluid 120 used to brew beverage 128 by pumping air through beverage material 114, so removing beverage material 1 14 along with filter 202 and cover 204 is easier to perform than the method described in FIG. 3.
- filter 202 may be made from a biodegradable material, compostable material and/or cellulose-based material.
- Cover 204 may also be made from a biodegradable material, compostable material and/or cellulose- based material.
- filter 202 may be made from paper, and cover 204 may be made from a biodegradable plastic or plant-based material.
- the combination of filter 202, cover 204, and beverage material 114 may be entirely biodegradable, compostable, and/or recyclable.
- cartridge body 200 Once separated from cartridge body 200, the combination of filter 202, cover 204, and beverage material 114 may then be used as compost, while cartridge body 200 may then be recycled as plastic and/or other compostable material such as paper.
- Such an approach is far simpler, and far more environmentally- friendly, than the related art approach of FIG. 3.
- filter 220 may comprise tab 406, either alternatively or in conjunction with tab 404 of cover 204.
- Tab 406 allows for filter 202 to be pulled or otherwise separated from cartridge body 200 when the combination of filter 202, cover 204, and beverage material 114 are removed from cartridge body 200.
- Tabs 404 and/or 406 may provide additional strength to the bond, connection, and/or coupling between filter 202 and cover 204, and an additional means for providing force to remove the combination of filter 202, cover 204, and beverage material 114 from cartridge body 200.
- FIGS. 5 and 6 illustrate exploded perspective views of a single-serve beverage cartridge in accordance with an aspect of the present disclosure.
- Cartridge 112 is shown with cover 204, filter 202, and cartridge body 200.
- Tabs 404 and 406 are shown, however, as described above, aspects of the present disclosure may have only one of such tabs 404 and/or 406 present as desired.
- Sides 208 of filter 202 are shown as being pleated in FIG. 5, although such pleating is optional in any aspect of the present disclosure.
- a location where inlet nozzle 140 may pierce cover 204 is shown as location 500.
- Cover 204 may be coupled to filter 202 as shown by arrow 502. This may make a combined unit 504, which may then be inserted into cartridge body 200 as shown by arrow 506. As shown in FIG. 6, part of filter 202, i.e., portion 402, may overlap rim 218. As cover 204 is coupled to filter 202, either as shown by arrow 600 or as a unit 504 described with respect to FIG. 5, cover 204 is coupled to rim 218 of cartridge body 200. Tabs 404 and/or 406 may be used to remove filter 202 and cover 204 from cartridge body 200 while allowing filter 202 and cover 204 to substantially remain coupled together.
- FIG. 7 illustrates a cross-sectional view of a single-serve beverage cartridge in accordance with an aspect of the present disclosure.
- filter is not coupled to ridge 206 as in the related art.
- a liner 700 is placed between the inner surface of cartridge body 200 and filter 202.
- Liner 700 may comprise tab 702, which may be used alone or in conjunction with tabs 404 and 406 as described with respect to FIG. 4.
- Liner 700 limits the direct contact between fluid 120 that is introduced into cartridge 112 and cartridge body 200. Because cartridge body 200 may leach chemicals and/or other materials into beverage 128, and be delivered via needle 158, liner 700 reduces the possibilities that such leaching will occur. Although heated fluid 120 will still likely leach material from cartridge body 200 through thermal exchange with cartridge body 200, liner 700 reduces and/or eliminates the pathways for such leached material from exiting cartridge 1 12 through needle 158 as part of beverage 158. Although liner 700 is shown as being substantially similar in shape to cartridge body 200, e.g., conforming to the side and bottom of cartridge body 200, liner 700 may take any shape as desired that limits the contact between fluid 120 and the inner wall of cartridge body 200.
- FIG. 8 illustrates a controller in accordance with an aspect of the present disclosure.
- the brewer 10 can include a controller or other processing unit, such as a microcontroller 800, shown schematically in FIG. 8.
- the microcontroller 800 may include an internal memory 802 and/or external memory 804 and can serve many different functions.
- the microcontroller 102 may serve to regulate the power provided to the pump 102, control system 100 through readings from sensor 124 and/or other sensors within system 100, accept input from user controls 806, or other controlling and/or monitoring functions. Many different functions are possible without departing from the scope of the present disclosure.
- the memory which may be internal memory 802 or external memory 804 to microcontroller 800, may be implemented in firmware and/or software implementation.
- the firmware and/or software implementation methodologies may be implemented with modules (e.g., procedures, functions, and so on) that perform the functions described herein.
- a machine-readable medium tangibly embodying instructions may be used in implementing the methodologies described herein.
- software codes may be stored in a memory and executed by a processor unit (e.g., microcontroller 800).
- Memory may be implemented within the processor unit or external to the processor unit.
- memory refers to types of long term, short term, volatile, nonvolatile, and/or other non-transitory memory and is not to be limited to a particular type of memory or number of memories, or type of media upon which memory is stored.
- FIGS. 9 A and 9B illustrate a recyclable beverage cartridge in accordance with an aspect of the present disclosure.
- FIG. 9A shows filter 900 located at a distance 900 from side 208 of the cartridge body 200.
- Distance 902 is a known distance, and may be approximately 0.25 inches, because cartridge body 200 is designed to fit within receptacle 110 in any orientation, and the outlet needle 158 is in a fixed location within receptacle 110.
- a toroidal volume may be defined by filter 900, having a height at least as high as dimension 216, with a tolerance for the location of the toroid such that filter 900 is not pierced and/or otherwise compromised by needle 158 when needle 158 pierces cartridge body 200.
- cartridge body 200 may be made from paper, pulp, cellulose and/or celluloid material, plant fibers, or other natural, renewable, recyclable, and/or compostable products, such that once the cartridge 112 has been used (i.e., nozzle 140 has pierced cover 204 and delivered fluid to cartridge 112 and beverage material 114 to brew a beverage 128), the entire cartridge 112 may be placed in a compost pile rather than separating cover 204 from cartridge body 200. As shown in FIG.
- filter 900 covers a cylindrical volume within cartridge 112, such that regardless of the orientation of cartridge 112 when placed in system 100, outlet nozzle 158 will pierce bottom 212 of cartridge 1 12 on one side of filter 900 while beverage material 1 14 is on an opposite side of filter 900.
- cartridge body 200 may be made from wood pulp and/or recycled paper products, which may be combined with food-safe binders such as starches and/or sugars, and/or other adhesives and/or binders that are safe for interactions with consumed products.
- food-safe binders such as starches and/or sugars, and/or other adhesives and/or binders that are safe for interactions with consumed products.
- an optional liner 904 which may be made of a different material than cartridge body 200, e.g., metal foil, a different natural, plant, and/or combination of materials, and/or may have a different density than cartridge body 200, such that contact between fluids entering cartridge 112 and cartridge body 200 are reduced when compared to cartridges 112 that do not include optional liner 904.
- Optional liner 904 may further comprise an optional portion 906 and/or optional tab 908 without departing from the scope of the present disclosure.
- the inclusion of liner 904 may minimize and/or prevent seepage of any flavors, binders, and/or other by-products from cartridge body 200, similar to how liner 700 minimizes leaching of by-products when cartridge body 200 is made from plastic.
- Liners 700 and/or 900 may be made from various materials; metal foil, plastic, paper, natural materials, etc. Liners 700 and/or 900 may provide several advantages and/or functions to cartridge 112. For example, and not by way of limitation, liner 700 and/or 900 may provide a hermetic and/or semi-hermetic seal for a portion of cartridge 1 12, such that beverage material 1 14 contained within cartridge 1 12 is substantially separated from outside air and/or other contaminants or oxidizing materials. Depending on the material used for cartridge 112, cartridge 112 may already provide a hermetic and/or semi-hermetic seal.
- liner 700 and/or 900 may provide a barrier between any liquid introduced into cartridge 1 12 and the cartridge body 200, such that the liquid introduced into cartridge 112 does not substantially contact cartridge body 200.
- Such liners 700 and/or 900 may also prevent any liquids, gasses, or fluids produced by the heat, pressure, and/or other operational conditions within beverage system 100 that are experienced by cartridge 112 from being delivered to mug 116 along with beverage 128.
- FIGS. 10 and 11 illustrate filter designs in accordance with an aspect of the present disclosure.
- Filter 900 may take any shape desired, and, as shown in FIG. 10, may be conical in shape rather than adopting the frustoconical shape of cartridge body 200 as shown in FIGS. 2 and 4-7. So long as filter 900 is not pierced by needle 158, filter 900 may take any desired shape, which may alter the brewing considerations and/or possibilities for various beverage materials 114. For example, and not by way of limitation, allowing filter 900 to reach the bottom of cartridge body 200, either as a conical shape shown in FIG. 10 or as a stepped frustoconical shape shown in FIG.
- fluid introduced into cartridge 112 will remain in contact with beverage material 114 present for a longer period of time before being delivered to mug 116 via needle 158.
- a different type of beverage material 114 may be placed in volume 910, which may also be separated from beverage material 114 by a second filter, to produce a hybrid-brewed beverage of the two beverage materials 114 present in cartridge 112.
- Such combinations and/or time duration of fluid/beverage material 114 contact differences are not possible in the related art, as the time duration is driven by fluid flow rates determined by pump 102.
- FIG. 12 illustrates a beverage cartridge in accordance with an aspect of the present disclosure.
- Cartridge 1 12 may also comprise a mechanism 1200 that may move, tighten, loosen, or otherwise interface with beverage material 1 14 once inlet nozzle 140 is inserted into cartridge 112.
- Some systems 100 have inlet nozzles 140 that move and/or rotate after piercing cover 204.
- inlet nozzle 140 can rotate in one direction for a first set of settings, and a second direction for a second set of settings.
- mechanism 1200 may be selectively engaged by inlet nozzle 140 based on the direction of movement and/or rotation of inlet nozzle 140.
- inlet nozzle 140 may comprise a tab 1202 that only engages mechanism 1200 when inlet nozzle 140 rotates in a clockwise direction.
- One side of tab 1202 may provide a surface that mechanism 1200 catches on and tightens when inlet nozzle 140 rotates in a clockwise direction, while another side of tab 1202 is a ramp or incline that will not engage mechanism 1200 when inlet nozzle 1200 rotates in a counter-clockwise direction.
- System 100 may allow for user input or automatic selection based on recognition and/or other identification of cartridge 112 to program the inlet nozzle 140 to rotate clockwise, which will allow tab 1202 to engage mechanism 1200 during brewing, or may allow for user input to program the inlet nozzle 140 to rotate counterclockwise, which will avoid engagement of mechanism 1200 during brewing.
- Other types of engagement between inlet nozzle 140 and mechanism 1200 are possible without departing from the scope of the present disclosure.
- Mechanism 1200 If mechanism 1200 is engaged, a first set of conditions, such as pressure, temperature, volume, etc., for beverage material 114 will be created by mechanism 1200. If mechanism 1200 is not engaged, a second set of conditions for beverage material 1 14 is created, which may be similar to the set of conditions created by system 100 when mechanism 1200 is not present within cartridge 112. [0075] Mechanism 1200, which is shown as a torsion spring, but may be any mechanism, may provide conditions for brewing that system 100 could not otherwise attain. For craft coffee beverages, e.g., "French press” coffee, "pour over” coffee, etc., system 100 may not be able to provide the pressure conditions within cartridge 112 without the use of mechanism 1200.
- mechanism 1200 If mechanism 1200 is not engaged, system 100 would produce a beverage similar to if not identical to the beverage produced if mechanism 1200 is not present. However, if mechanism 1200 is engaged during brewing, different pressures, localized temperatures, reduced volumes, etc., may produce a different beverage from the same cartridge 112.
- mechanism 1200 is shown as a torsion spring, other mechanisms are possible within the scope of the present disclosure. Further, beverage material 114 may be located at specific locations within cartridge 112, such as along the side 208, along the bottom 212, etc., such that the combination of type of mechanism 1200 and placement of beverage material 114 within cartridge 112 provides operational advantages within system 100.
- mechanism 1200 may provide additional pressure to beverage material 114 when mechanism 1200 is engaged by inlet nozzle 140.
- System 100 may be programmed to introduce fluid to cartridge 1200 for a certain amount of time and then stop introducing fluid. System 100 may then allow the fluid to drain from cartridge 112 for a certain amount of time, and then engage mechanism 1200 to pressurize the added fluid out of cartridge 112 through outlet needle 158. System 100 may then add more fluid to cartridge 112 and repeat these steps. Such an approach is similar to a "pour over" style of coffee brewing. Similar mechanisms 1200, beverage material 114 placement, and/or fluid delivery techniques may be combined to produce other types of brewing techniques in system 100. Such techniques are not currently employed in related systems 100. Variable Porosity and Flavor Additives
- FIG. 13 illustrates a beverage cartridge in accordance with an aspect of the present disclosure.
- Cartridge 112 may comprise a filter 1300 which has a variable porosity.
- a portion 1302 of filter 1300 may have a first porosity value, while portion 1304 of filter 1300 may have a second porosity value.
- fluid introduced into cartridge 112 may remain in portions of filter 1300 longer than in other portions of filter 1300.
- portion 1302 may be less porous than portion 1304. As such, fluid 120 that is introduced into cartridge 112 will not flow through portion 1302 as fast, or at all, as fluid 120 that reaches the level of portion 1304. This may increase the time that fluid remains in contact with beverage material 114 that is contained within portion 1302. As the fluid level rises in cartridge 112, fluid 120 will flow out of portion 1304. This allows for more precise control of the time that fluid 120 remains in contact with beverage material 114.
- system 100 e.g., fluid delivery flow rate, fluid delivery temperatures, etc., more precise brewing profiles may be achieved with system 100 through the use of variable flow rate filter 1300.
- cover 204 may be wrapped around rim 218 and adhered to a larger surface of rim 218.
- the cartridge body 200 may be placed in a receptacle that allows for only small amounts of expansion of the cartridge body 200.
- the sealing surface of cover 204 to cartridge body 200 along rim 218 is the location of pressure blowouts experienced by cartridge 112.
- increasing the pressure and force vectors that may be experienced at that location by encasing rim 218 with cover 204, and applying adhesive 400 to a larger surface of rim 218 (e.g., on both sides of rim 218) allows for greater pressure to be applied within cartridge 112 with fluid 120.
- cartridge body 200 may have a textured surface, specific color, other identifying marks, and/or indicia 1320 such that brewer 100 may recognize cartridge 1 12 as a specific type of cartridge 1 12. This recognition may be used to determine brewing characteristics, for rewards programs, and/or for any other reason.
- cartridge body 200 may be made from cellulose-based materials, and cartridge 1 12 may be placed under pressure when fluid 120 is delivered to cartridge 112, the pressure and/or water temperature may soften cartridge body 200.
- the pressure created by brewer 100 in delivering fluid 120 to cartridge 112 may allow for deformation of the surface of cartridge body 200.
- the fluid 120 after passing through beverage material 114 and becoming beverage 128, may change the color of cartridge body 200.
- the use of a given cartridge 112 in brewer 100 may alter and/or otherwise change the indicia 1320 such that the indicia 1320 no longer indicates the same information to brewer 100.
- indicia 1320 will allow brewer 100 to minimize reuse of the same cartridge 1 12, by alerting the user to reuse of a given cartridge 1 12, and/or minimize the recognition of cartridge 1 12 multiple times in rewards and/or accounting functions performed by brewer 100. Although indicated at a certain location on cartridge 1 12, indicia 1320 may appear anywhere on cartridge 1 12 without departing from the scope of the present disclosure.
- cartridges 112 have added flavors and/or essences infused into beverage material 114.
- some coffee beverages have hazelnut or caramel flavors infused or added to the beverage material 114.
- the process of infusing such flavors into beverage material 1 14 may add to the cost of cartridge 1 12, and/or the beverage material 1 14 may be degraded or otherwise altered by the infusion process.
- materials 1306 and/or 1308 may be added to and/or infused into cartridge body 200, which may provide a more economical approach to inclusion of various additives in cartridge 112.
- an essential oil may be added to cartridge body 200 at location 1506 and/or infused into a portion of or all of cartridge body 200.
- cartridge body 200 in an aspect of the present disclosure is cellulose-based, and is manufactured using oils and/or other binders, the infusion process may be less expensive than infusion of the same essential oil into beverage material 114.
- infusion of the essential oil into cartridge body 200 may have fewer deleterious effects on beverage material 114 as well as fewer deleterious effects on the essential oil.
- a smaller amount of essential oil may be needed to provide the same flavors and/or other effects in the resultant beverage by placing the essential oil at location 1306 and/or 1308 than with beverage material 114.
- Filter 1300 may also have a specialized shape 1310.
- Shape 1310 may be any shape.
- shape 1310 may be used to control the amount of time that fluid remains in contact with beverage material 114.
- Many shapes 1310 can be employed without departing from the scope of the present disclosure.
- FIG. 14 illustrates a beverage cartridge in accordance with an aspect of the present disclosure.
- Some cartridges 112 do not have a body 200 that fully encloses the beverage material 114.
- Such cartridges 112 may be referred to as "soft pods.”
- One drawback of soft pods is that the beverage material 114 may be exposed to air or other oxidizing environments, which may deleteriously affect the beverage material 114.
- cartridge 1400 may be designed to have a separation line that exposes filter 1300.
- cartridge 1400 When placed in the system 100, cartridge 1400 has a cartridge body 1402 that separates from separated portion 1404 when fluid is introduced into cartridge 1400.
- the additional pressure introduced into cartridge 1400 by fluid 1400 may provide separation between cartridge body 1402 and separated portion 1404 such that the body 1402 and separated portion 1404 separate along upper separation line 1406 and lower separation line 1408. Separated portion 1404 moves away from body 1402 in direction 1408.
- the upper and lower separation lines 1406/1408 may be a perforation line on cartridge 1400. Since the pressure in system 100 may be controlled, the pressure system 100 produces can be controlled to separate cartridge 1400 into body 1402 and separated portion 1404. Filter 202 may couple body 1402 and separated portion 1404, or separated portion 1404 may not completely separate from body 1402. So long as pressure is released by the separation of body 1402 and separated portion 1404, fluid entering cartridge 1400 will flow through filter 202 once separated portion 1404 has separated from body 1402. In such an aspect of the present disclosure, cartridge 1400 may provide better protection of beverage material 114 than a soft pod, and may further reduce the cost of production of cartridge 1400.
- the present disclosure provides several advantages over the related art approaches.
- the present disclosure allows for easy separation of compostable and recyclable materials, and may allow for a cartridge that may be home-compostable (as opposed to compostable at a commercial facility).
- the present disclosure also allows for safer operation of beverage systems 100 that employ cartridges 112, in that possible unwanted by-products produced by cartridge 112 during the operation of beverage system 100 are not produced and/or consumed.
- the present disclosure allows for different types of filtration of beverage material 114, which may be desirable depending on the volume of beverage 128 to be produced from beverage material 114 in cartridge 112.
- the present disclosure also allows for additional types of beverages 128 to be produced, as well as allowing for richer, more flavorful beverages to be produced by currently deployed beverage systems 100.
- the present disclosure also provides upgrades to single-serve beverage systems 100 which may enable these systems to employ brewing methods, such as craft brewing methods, that present systems 100 cannot accommodate.
