Definitions
- the present invention relates to a single-serve beverage ingredient package of the type which may be used, for example, in a Keurig® style coffee brewing machine. More specifically, the present invention relates to a beverage package which is entirely biodegradable and compostable and made from readily renewable resources.
- beverage ingredient packages for providing one or more ingredients (such as coffee) are known in the art and are commercially available.
- the popularity of such single-serve beverage ingredient packages has grown exponentially over the past decade along with the popularity of single serve brewers such as the coffee brewers sold under the Keurig® trademark.
- Such beverage ingredient packages typically hold dry ingredients, such as coffee, tea, cocoa or the like, for a single beverage serving.
- the package is placed into a compartment of a brewing machine and then penetrated with a fluid injector and a fluid extractor.
- a brewing medium such as hot water, is then injected into the package such that the dry contents of the package are at least partially dissolved by or form a mixture with the brewing medium.
- the solution or mixture is then extracted from the package, the result being a drinkable beverage such as coffee, tea, hot cocoa or the like.
- the aforementioned beverage packages typically comprise a container, a filter, and a cover.
- the container and filter are typically made from petroleum-based plastic materials which are neither biodegradable nor compostable. Such materials are also not made from readily renewable resources.
- the cover is typically made of a metal foil or a metal foil laminate which is glued to the top of the container. Neither the metal foil of the cover nor the glue are typically biodegradable, compostable or made from readily renewable resources.
- the aforementioned beverage packages give rise to significant environmental concerns.
- First, neither the container, the filter nor the cover is made from readily renewable resources.
- Second, neither the container, the filter nor the cover is easily recycled.
- Third, neither the container, the filter nor the cover is made from materials which are biodegradable or compostable. As such, the beverage packages typically end up in landfills contributing to the environmental concerns associated with disposal of trash.
- the present invention addresses the limitation of prior art single-serve beverage ingredient packages by providing a cup and a lid, each of which is biodegradable and compostable and made of readily renewable resources such as the fibrous plant materials available from bamboo, bagasse and other plants which grow abundantly and more rapidly than trees. Such materials are processed in a manner which results in a durable, heat-resistant composition which may be readily molded into the desired shape of the cup and lid.
- the present invention also includes a filter assembly including one or more layers of biodegradable, compostable filter paper made from readily renewable resources coupled to a support ring.
- the support ring may be die-cut from a biodegradable, compostable paperboard or may be formed from a polymer such as a polylactic acid (PLA) and poly-L-lactide (PLLA). These polymers are also biodegradable and compostable.
- the materials used to form the paperboard, the PLA or the PLLA are also readily renewable.
- the support ring has a diameter adapted to permit the support ring to engage a ledge formed into the interior of the cup.
- the support ring is also formed with a plurality of teeth along the outer circumference which engage the wall of the cup adjacent the ledge to prevent the filter from becoming disengaged from the ledge. As such, only compostable and biodegradable materials made from readily renewable resources are employed to form the single-serve beverage ingredient package.

- a single-serve beverage ingredient packaging comprising a cup 10 , a lid 30 and a filter 50 is illustrated in the drawings.
- the cup 10 includes a generally flat base 12 , an upper lip 14 surrounding an open top 16 and an upstanding side wall 18 extending between the base 12 and lip 14 .
- the side wall 18 includes a lower section 20 and upper section 22 separated by an inwardly extending shelf or ledge 24 .
- the side wall 18 surrounds a chamber 26 having an upper first chamber section 28 between the ledge 24 and the lip 14 , a lower second chamber section 29 between the ledge 24 and the base 12 .
- the lower section 20 of the side wall 18 is shown having an angle with respect to the base of 98°.
- the upper section 22 extends at an angle with respect to the plane defined by the base 12 of 100°.
- a lid 30 is provided to close the open top 16 of the cup 10 to seal the chamber 26 .
- the cover 30 has an outer lip 32 and a center section 34 . Extending between the lip 32 and the center section 34 is a peripheral valley 33 defined by an inner wall 36 extending downwardly from the outer edge of the center section 34 , an outer wall 40 extending downwardly from the inner edge of the outer lip 32 and a bottom wall 38 joining the bottom of the inner wall 36 and the bottom of the outer wall 40 .
- the inner wall extends at an angle of 110° from the bottom wall 38 .
- the outside diameter of the cover is adapted to the diameter of the upper section 22 of wall 18 of the cup 10 such that, when the cover 30 is joined to the cup 10 as shown in FIG. 2 , there is a firm frictional fit which prevents the lid 30 from being accidentally dislodged from the cup.
- a biodegradable, compostable adhesive made from readily renewable resources may also be employed to fasten the cover 30 to the cup 10 .
- the filter assembly 50 includes a support ring 52 best shown in FIG. 3 and at least one filter paper layer, one of which is shown in FIG. 4 . As shown in FIG. 5 , the support ring 52 may also be sandwiched between an upper filtration layer 54 and a lower filtration layer 56 . Alternatively, only a single filtration layer 54 may be employed as shown in FIG. 6 .
- the support ring as shown in FIG. 3 , has an open center section 60 , an intermediate section 62 and an outer section comprising at least one member adapted to engage the side wall 18 of the cup 10 and, preferably, a plurality of peripheral teeth 64 .
- the filtration layers 54 and 56 completely cover the open center section 60 and at least a portion of the intermediate section 62 .
- the support ring may be made of polylactic acid (PLA), a thermoplastic aliphatic polyester derived from a readily renewable resource such as corn starch or sugar cane. Whichever specific polymer (or form thereof) is used, the polymer should have a melting temperature above the brewing temperature to be employed. Since most beverages are brewed at or below 100° C., the boiling point of water, the melting point of the polymer should be higher than 100° C.
- PLA polylactic acid
- thermoplastic aliphatic polyester derived from a readily renewable resource such as corn starch or sugar cane.
- poly-L-lactide may be employed since this form of the polymer has a crystallinity of around 37% and a melting temperature of about 175° C. which is well above the temperature at which coffee, tea, cocoa or the like are typically brewed.
- PLA and PLLA not only are produced from renewable resources, but is also environmentally friendly because these materials are readily recycled and are also both biodegradable and compostable.
- biodegradable means a substance or object capable of being decomposed by bacteria or other living organisms.
- compostable means a substance that (1) breaks down at essentially the same rate as paper; (2) disintegrates in the compost; and (3) does not produce any toxic material such that the compost can support plant growth.
- a resource is “readily renewable” if it is derived from plant materials which grow abundantly or more rapidly than trees. Examples of such plant materials include bamboo or bagasse.
- a resource which is recycled, such as paper made from whatever source, is also deemed to be “readily renewable” because it is abundantly available and its use will not directly result in the exhaustion of non-renewable resources such as oil or the harvesting of trees.
- the filter 50 is placed over the cup and lowered until the outer circumference of the intermediate section 62 of the ring 52 engages (e.g. comes to rest upon) the ledge 24 of the cup 10 as shown in FIG. 6 .
- the teeth 64 will be deflected upwardly by the wall 18 of the cup 10 .
- the teeth 64 press against the upper section 22 of the wall 18 of the cup 10 to secure the filter 50 in place and prevent the filter 50 from lifting off or disengaging from the ledge 24 .
- coffee, tea or cocoa or some other dry ingredient to be brewed is placed in the cup 10 and over the filter 50 such that the dry ingredient is located in the first chamber section 28 .
- the filter 50 prevents the dry ingredient from reaching the lower second chamber section 29 of cup 10 .
- the term “ingredient” is used broadly so as to encompass either a single dry ingredient or a blend or mixture of dry ingredients.
- the cover 30 is pierced with an injector and the base 12 is pierced with an extractor.
- a fluid brewing medium such as water or the like is injected through the injector into the upper first chamber section 28 of cup 10 where it mixes with and/or dissolves the dry beverage ingredient previously placed in the cup 10 .
- the mixture or solution then passes through the upper filtration layer 54 , through the center open section 60 of the filter support ring 52 and through the lower filtration layer 56 (if a lower filtration layer has been provided) into the lower second chamber section 29 of the chamber 26 .
- the undissolved, unmixed residue of the dry ingredient is retained in the upper first chamber section 28 of chamber 26 by the filter 50 .
- the mixture or solution exits the lower section portion 29 of the chamber through the base 12 via the extractor and into a coffee mug or the like so that the beverage may be consumed.
- the cup 10 , and lid 30 and filtration layers 52 and 56 are all made from paper-like substances formed from fibrous plant materials which grow swiftly such as grasses like wheat, bamboo and sugar cane.
- the resources are swiftly replenishable because they grow quickly and are abundant.
- such resources may be recycled paper or other recycled materials which are biodegradable and compostable.
- the filter support ring is also made of materials formed from readily renewable resources which are likewise both biodegradable and compostable, e.g., PLA or PLLA. Such materials may also be employed in the construction of the cup 10 and lid 30 .
- BPA bisphenol A
- the lid 30 is adapted to be penetrated by a fluid injector.
- the base 12 is adapted to be penetrated by a fluid extractor.
- hot water or some other fluid is passed through the lid 30 via the injector where it mixes with or dissolves a granular material such as coffee, tea or cocoa in the upper first section 28 of the chamber 26 .
- the mixture or solution then passes through the filter 50 into the lower second section 29 of the chamber 26 while leaving any residue behind in the first section 28 of chamber 26 .
- the brewed beverage then exits the container through an extractor which has penetrated the base 12 .
- the cup and lid may be made of a non-porous molded paper-like substance or may be made of the same materials as the filter support ring, e.g., PLA or PLLA.
- the filter may be integrally formed of a material such as PLA or PLLA without a center opening or separate filtration layers by providing perforations large enough to permit the brewed mixture or solution of coffee, tea or the like to pass through the filter and at the same time small enough to prohibit any substantial quantity of the dry material or residue from passing through the filter.
- FIG. 7 shows a lid 30 having an outer lip 32 , center section 34 and peripheral valley 33 defined by an inner wall 36 and outer wall 40 and a bottom wall 38 like the lid 30 shown in FIG. 6 .
- a plurality of teeth 41 which flex and engage the upper section 22 of the wall 18 of cup 10 when the cover 30 is coupled to the cup 10 . Through such engagement, the teeth 41 inhibit separation of the lid 30 from the cup 10 .
- Such teeth 41 are easily formed into the lid 30 if the lid is molded from a material such as PLLA.
- FIG. 8 shows an alternative embodiment for securing the filter 50 in place inside the cup 10 .
- the filter support ring 52 is replaced with a filter support structure 100 .
- the filter support structure has an open bottom 108 and a wall 101 which is in face-to-face engagement with the inside surface of the lower section 20 of the side wall 18 of the cup 10 .
- Filter support structure 100 also includes a ledge 102 which is adapted to engage the shelf or ledge 24 of the cup 10 .
- the top 106 of the ledge 102 provides a support for the peripheral edge of a filtration layer 54 .
- the filtration layer 54 may be bonded to the structure 100 during molding of the support structure 100 such as when the support structure 100 is made of PLLA.
- the filtration layer may be bonded to the support structure using a biodegradable and compostable adhesive.
- Extending outwardly from the wall 101 are a plurality of teeth 104 which engage the inner surface of the lower section 20 of the side wall 18 of cup 10 to firmly fix the support structure 100 in place within the lower chamber 29 of cup 10 .
- FIG. 9 shows still another alternative arrangement for securing the lid 30 to the cup 10 .
- a ring 120 is provided. Ring 120 has a wall 122 . Teeth 124 project outwardly from wall 122 . Teeth 126 project inwardly from wall 122 .
- the ring 120 is fitted around the outer wall 40 of the lid 30 . The teeth 126 engage the outer wall 40 of the lid 30 to couple the ring 120 to the lid 30 .
- the assembled lid 30 and ring 120 are inserted into the top of the cup 10 . This causes the outer teeth 124 to engage the inner surface of the upper section 22 of the wall of the cup 10 to inhibit separation of the ring 120 and lid 30 from the cup.
- the ring 120 may be made of PLA or PLLA while the lid 30 and cup 10 are formed of readily renewable, biodegradable and compostable materials made from bamboo, wheat grass, bagasse or the like.
- FIGS. 10-12 show an alternative filter arrangement comprising a virgin paperboard die-cut ring 52 sandwiched between two layers of a die-cut, heat-sealable filter paper 54 .
- the paperboard ring includes an impermeable outer peripheral section 62 surrounding a center open section 60 .
- the two layers of filter paper 54 have a slightly larger outside diameter than the ring 52 .
- the two layers of filter paper can be adhered to the impermeable outer peripheral section 62 and then to the wall 18 and ledge 24 of the cup 10 . They also retain the grounds of the coffee, tea or other item to be brewed in the upper first chamber section of the cup while permitting the brewed solution or mixture to pass through the center open section 60 into the lower second chamber section 29 .
- any food-safe, biodegradable and compostable adhesive may be employed to create such a bond.
- the tolerances between the wall 18 and outer edge of the ring 52 may be such that a sufficient frictional bond is created simply by inserting the filter into the cup and forcing the filter into engagement with the ledge 24 of cup 10 .
Abstract
Single-serve ingredient packages made from materials which are biodegradable and compostable and which are derived from readily renewable resources environmentally advantageous and may be used to brew beverages such as coffee, tea and cocoa.
Description
- This application is a non-provisional application of Application No. 61/821,194, filed May 8, 2013 and claims priority from that application which is also deemed incorporated by reference in its entirety in this application.
- Not applicable
- I. Field of the Invention
- The present invention relates to a single-serve beverage ingredient package of the type which may be used, for example, in a Keurig® style coffee brewing machine. More specifically, the present invention relates to a beverage package which is entirely biodegradable and compostable and made from readily renewable resources.
- II. Related Art
- Various types of beverage packages for providing one or more ingredients (such as coffee) are known in the art and are commercially available. The popularity of such single-serve beverage ingredient packages has grown exponentially over the past decade along with the popularity of single serve brewers such as the coffee brewers sold under the Keurig® trademark. Such beverage ingredient packages typically hold dry ingredients, such as coffee, tea, cocoa or the like, for a single beverage serving. The package is placed into a compartment of a brewing machine and then penetrated with a fluid injector and a fluid extractor. A brewing medium, such as hot water, is then injected into the package such that the dry contents of the package are at least partially dissolved by or form a mixture with the brewing medium. The solution or mixture is then extracted from the package, the result being a drinkable beverage such as coffee, tea, hot cocoa or the like.
- The aforementioned beverage packages typically comprise a container, a filter, and a cover. The container and filter are typically made from petroleum-based plastic materials which are neither biodegradable nor compostable. Such materials are also not made from readily renewable resources. The cover is typically made of a metal foil or a metal foil laminate which is glued to the top of the container. Neither the metal foil of the cover nor the glue are typically biodegradable, compostable or made from readily renewable resources.
- The aforementioned beverage packages give rise to significant environmental concerns. First, neither the container, the filter nor the cover is made from readily renewable resources. Second, neither the container, the filter nor the cover is easily recycled. Third, neither the container, the filter nor the cover is made from materials which are biodegradable or compostable. As such, the beverage packages typically end up in landfills contributing to the environmental concerns associated with disposal of trash.
- In view of the foregoing, there is a real need for a single-serve beverage ingredient package constructed of biodegradable and compostable materials made from readily renewable resources that will achieve acceptable results when brewing coffee, tea, cocoa or the like in a single-serve brewer.
- The present invention addresses the limitation of prior art single-serve beverage ingredient packages by providing a cup and a lid, each of which is biodegradable and compostable and made of readily renewable resources such as the fibrous plant materials available from bamboo, bagasse and other plants which grow abundantly and more rapidly than trees. Such materials are processed in a manner which results in a durable, heat-resistant composition which may be readily molded into the desired shape of the cup and lid. The present invention also includes a filter assembly including one or more layers of biodegradable, compostable filter paper made from readily renewable resources coupled to a support ring. The support ring may be die-cut from a biodegradable, compostable paperboard or may be formed from a polymer such as a polylactic acid (PLA) and poly-L-lactide (PLLA). These polymers are also biodegradable and compostable. The materials used to form the paperboard, the PLA or the PLLA are also readily renewable. The support ring has a diameter adapted to permit the support ring to engage a ledge formed into the interior of the cup. The support ring is also formed with a plurality of teeth along the outer circumference which engage the wall of the cup adjacent the ledge to prevent the filter from becoming disengaged from the ledge. As such, only compostable and biodegradable materials made from readily renewable resources are employed to form the single-serve beverage ingredient package.

- A single-serve beverage ingredient packaging comprising a
cup 10, alid 30 and afilter 50 is illustrated in the drawings. Thecup 10 includes a generallyflat base 12, anupper lip 14 surrounding anopen top 16 and anupstanding side wall 18 extending between thebase 12 andlip 14. Theside wall 18 includes alower section 20 andupper section 22 separated by an inwardly extending shelf orledge 24. Theside wall 18 surrounds achamber 26 having an upperfirst chamber section 28 between theledge 24 and thelip 14, a lowersecond chamber section 29 between theledge 24 and thebase 12. Thelower section 20 of theside wall 18 is shown having an angle with respect to the base of 98°. Theupper section 22 extends at an angle with respect to the plane defined by thebase 12 of 100°. - As shown in
FIG. 2 , alid 30 is provided to close theopen top 16 of thecup 10 to seal thechamber 26. Thecover 30 has anouter lip 32 and acenter section 34. Extending between thelip 32 and thecenter section 34 is aperipheral valley 33 defined by aninner wall 36 extending downwardly from the outer edge of thecenter section 34, anouter wall 40 extending downwardly from the inner edge of theouter lip 32 and abottom wall 38 joining the bottom of theinner wall 36 and the bottom of theouter wall 40. The inner wall extends at an angle of 110° from thebottom wall 38. The outside diameter of the cover, as defined by theouter wall 40, is adapted to the diameter of theupper section 22 ofwall 18 of thecup 10 such that, when thecover 30 is joined to thecup 10 as shown inFIG. 2 , there is a firm frictional fit which prevents thelid 30 from being accidentally dislodged from the cup. A biodegradable, compostable adhesive made from readily renewable resources may also be employed to fasten thecover 30 to thecup 10. - As shown in
FIGS. 3-6 , afilter assembly 50 is provided. Thefilter assembly 50 includes asupport ring 52 best shown inFIG. 3 and at least one filter paper layer, one of which is shown inFIG. 4 . As shown inFIG. 5 , thesupport ring 52 may also be sandwiched between anupper filtration layer 54 and alower filtration layer 56. Alternatively, only asingle filtration layer 54 may be employed as shown inFIG. 6 . - The support ring, as shown in
FIG. 3 , has anopen center section 60, anintermediate section 62 and an outer section comprising at least one member adapted to engage theside wall 18 of thecup 10 and, preferably, a plurality ofperipheral teeth 64. The filtration layers 54 and 56 completely cover theopen center section 60 and at least a portion of theintermediate section 62. - The support ring may be made of polylactic acid (PLA), a thermoplastic aliphatic polyester derived from a readily renewable resource such as corn starch or sugar cane. Whichever specific polymer (or form thereof) is used, the polymer should have a melting temperature above the brewing temperature to be employed. Since most beverages are brewed at or below 100° C., the boiling point of water, the melting point of the polymer should be higher than 100° C.
- As such, poly-L-lactide (PLLA) may be employed since this form of the polymer has a crystallinity of around 37% and a melting temperature of about 175° C. which is well above the temperature at which coffee, tea, cocoa or the like are typically brewed. PLA and PLLA not only are produced from renewable resources, but is also environmentally friendly because these materials are readily recycled and are also both biodegradable and compostable.
- Other materials meeting the temperature and composting requirements set forth above which are made from renewable resources may be employed for the filter support ring without deviating from the invention.
- As should be clear from the foregoing, the use of biodegradable, compostable materials made from readily renewable resources is a key advantage of the present invention. As used herein, the term “biodegradable” means a substance or object capable of being decomposed by bacteria or other living organisms. The term “compostable” means a substance that (1) breaks down at essentially the same rate as paper; (2) disintegrates in the compost; and (3) does not produce any toxic material such that the compost can support plant growth. A resource is “readily renewable” if it is derived from plant materials which grow abundantly or more rapidly than trees. Examples of such plant materials include bamboo or bagasse. A resource which is recycled, such as paper made from whatever source, is also deemed to be “readily renewable” because it is abundantly available and its use will not directly result in the exhaustion of non-renewable resources such as oil or the harvesting of trees.
- Assembly of the
cup 10,filter 50 andlid 30 to form a single-serve beverage ingredient package is relatively straightforward and simple. First, thefilter 50 is placed over the cup and lowered until the outer circumference of theintermediate section 62 of thering 52 engages (e.g. comes to rest upon) theledge 24 of thecup 10 as shown inFIG. 6 . As the filter is so lowered into the cup, theteeth 64 will be deflected upwardly by thewall 18 of thecup 10. With thefilter 50 seated on or engaging theledge 24, theteeth 64 press against theupper section 22 of thewall 18 of thecup 10 to secure thefilter 50 in place and prevent thefilter 50 from lifting off or disengaging from theledge 24. - Next, coffee, tea or cocoa or some other dry ingredient to be brewed is placed in the
cup 10 and over thefilter 50 such that the dry ingredient is located in thefirst chamber section 28. Thefilter 50 prevents the dry ingredient from reaching the lowersecond chamber section 29 ofcup 10. The term “ingredient” is used broadly so as to encompass either a single dry ingredient or a blend or mixture of dry ingredients. Finally, thelid 30 is secured in place as illustrated inFIG. 6 . - When the package described above is used in a brewer such as those sold by Keurig®, the
cover 30 is pierced with an injector and thebase 12 is pierced with an extractor. A fluid brewing medium such as water or the like is injected through the injector into the upperfirst chamber section 28 ofcup 10 where it mixes with and/or dissolves the dry beverage ingredient previously placed in thecup 10. The mixture or solution then passes through theupper filtration layer 54, through the centeropen section 60 of thefilter support ring 52 and through the lower filtration layer 56 (if a lower filtration layer has been provided) into the lowersecond chamber section 29 of thechamber 26. The undissolved, unmixed residue of the dry ingredient is retained in the upperfirst chamber section 28 ofchamber 26 by thefilter 50. The mixture or solution exits thelower section portion 29 of the chamber through thebase 12 via the extractor and into a coffee mug or the like so that the beverage may be consumed. - To achieve a container made entirely of materials comprising renewable resources and which are biodegradable and compostable, the
cup 10, andlid 30 andfiltration layers cup 10 andlid 30. - Many recycled paper products include trace levels of bisphenol A (BPA) or other chemicals used in the inks or coatings on the paper which is recycled. Thus, when recycled paper is used as a source material, care should be taken to encapsulate or remove such chemicals so unsafe levels are not consumed. Removal may add to cost and encapsulation may add to cost or inhibit biodegradability and compostability. These types of problems can be avoided by using virgin paper products made from plants having a short growing cycle which do not contain such harmful chemicals.
- Use of the aforementioned materials and similar materials also permit brewing to occur within the package itself. The
lid 30 is adapted to be penetrated by a fluid injector. Thebase 12 is adapted to be penetrated by a fluid extractor. As such, hot water or some other fluid is passed through thelid 30 via the injector where it mixes with or dissolves a granular material such as coffee, tea or cocoa in the upperfirst section 28 of thechamber 26. The mixture or solution then passes through thefilter 50 into the lowersecond section 29 of thechamber 26 while leaving any residue behind in thefirst section 28 ofchamber 26. The brewed beverage then exits the container through an extractor which has penetrated thebase 12. - Various modifications may be made without deviating from the invention. Such modifications may concern the shapes and sizes of the various components and the materials from which the components are made. By way of example, the cup and lid may be made of a non-porous molded paper-like substance or may be made of the same materials as the filter support ring, e.g., PLA or PLLA. Further, the filter may be integrally formed of a material such as PLA or PLLA without a center opening or separate filtration layers by providing perforations large enough to permit the brewed mixture or solution of coffee, tea or the like to pass through the filter and at the same time small enough to prohibit any substantial quantity of the dry material or residue from passing through the filter.
- Other examples of modifications are shown in
FIGS. 7-9 .FIG. 7 shows alid 30 having anouter lip 32,center section 34 andperipheral valley 33 defined by aninner wall 36 andouter wall 40 and abottom wall 38 like thelid 30 shown inFIG. 6 . However, extending outwardly from theouter wall 40 are a plurality ofteeth 41 which flex and engage theupper section 22 of thewall 18 ofcup 10 when thecover 30 is coupled to thecup 10. Through such engagement, theteeth 41 inhibit separation of thelid 30 from thecup 10.Such teeth 41 are easily formed into thelid 30 if the lid is molded from a material such as PLLA. -
FIG. 8 shows an alternative embodiment for securing thefilter 50 in place inside thecup 10. As shown inFIG. 8 , thefilter support ring 52 is replaced with afilter support structure 100. The filter support structure has anopen bottom 108 and awall 101 which is in face-to-face engagement with the inside surface of thelower section 20 of theside wall 18 of thecup 10.Filter support structure 100 also includes aledge 102 which is adapted to engage the shelf orledge 24 of thecup 10. The top 106 of theledge 102 provides a support for the peripheral edge of afiltration layer 54. Thefiltration layer 54 may be bonded to thestructure 100 during molding of thesupport structure 100 such as when thesupport structure 100 is made of PLLA. - Alternatively, the filtration layer may be bonded to the support structure using a biodegradable and compostable adhesive. Extending outwardly from the
wall 101 are a plurality ofteeth 104 which engage the inner surface of thelower section 20 of theside wall 18 ofcup 10 to firmly fix thesupport structure 100 in place within thelower chamber 29 ofcup 10. -
FIG. 9 shows still another alternative arrangement for securing thelid 30 to thecup 10. As shown inFIG. 9 , aring 120 is provided.Ring 120 has awall 122.Teeth 124 project outwardly fromwall 122.Teeth 126 project inwardly fromwall 122. During assembly, thering 120 is fitted around theouter wall 40 of thelid 30. Theteeth 126 engage theouter wall 40 of thelid 30 to couple thering 120 to thelid 30. Next, the assembledlid 30 andring 120 are inserted into the top of thecup 10. This causes theouter teeth 124 to engage the inner surface of theupper section 22 of the wall of thecup 10 to inhibit separation of thering 120 andlid 30 from the cup. Thering 120 may be made of PLA or PLLA while thelid 30 andcup 10 are formed of readily renewable, biodegradable and compostable materials made from bamboo, wheat grass, bagasse or the like. -
FIGS. 10-12 show an alternative filter arrangement comprising a virgin paperboard die-cut ring 52 sandwiched between two layers of a die-cut, heat-sealable filter paper 54. The paperboard ring includes an impermeable outerperipheral section 62 surrounding a centeropen section 60. The two layers offilter paper 54 have a slightly larger outside diameter than thering 52. As such, the two layers of filter paper can be adhered to the impermeable outerperipheral section 62 and then to thewall 18 andledge 24 of thecup 10. They also retain the grounds of the coffee, tea or other item to be brewed in the upper first chamber section of the cup while permitting the brewed solution or mixture to pass through the centeropen section 60 into the lowersecond chamber section 29. If using heat to join the filter paper to either thering 52 of the filter orside wall 18 of the cup results in an inadequate bond, a small amount of any food-safe, biodegradable and compostable adhesive may be employed to create such a bond. Alternatively, the tolerances between thewall 18 and outer edge of thering 52 may be such that a sufficient frictional bond is created simply by inserting the filter into the cup and forcing the filter into engagement with theledge 24 ofcup 10. - The foregoing description is intended to explain the various features and advantages, but is not intended to be limiting. The scope of the invention is defined by the following claims which are also intended to cover a reasonable range of equivalents.
