Disclosed is a single brew beverage cartridge for use in a brewing apparatus. The cartridge includes a lid and a cup shaped filter suspended below the lid and in which a beverage brewing ingredient is held. The lid includes an annular collar to prevent the lid from deforming when a needle of the brewing apparatus pierces it during the brewing process. Preferably the cartridge is formed of materials, e.g., paper/paperboard, so that it is compostable and biodegradable.

1. A single brew beverage cartridge for use in a beverage brewing apparatus, the apparatus comprising a brewing chamber, a supply of a hot liquid, and a piercing member, said cartridge being compostable and biodegradable and comprising a filter, a beverage brewing ingredient, and a lid, said lid comprising a piercable portion, a flange and a collar, said collar comprising a sidewall having a peripheral surface projecting downward from said flange and extending about a longitudinal axis, said lid being resistant to flexure when a force is applied to said piercable portion of said lid in a direction parallel to said longitudinal axis, said filter comprising a cup-shaped hollow body holding said beverage brewing ingredient therein, said lid sealing said beverage brewing ingredient in said cup-shaped hollow body, said cup-shaped hollow body being formed of a single layer of paper or paperboard having a slightly tapering cylindrical sidewall and a generally planar bottom wall, said cylindrical sidewall having first and second cylindrical sidewall portions, said first cylindrical sidewall portion being located above said second cylindrical sidewall portion, said second cylindrical sidewall portion having a lower end terminating at said generally planar bottom wall, said second cylindrical sidewall portion and said generally planar bottom wall providing a substantially large surface area through which a brewed beverage can pass, said first cylindrical sidewall portion comprising a polymer welding said first cylindrical sidewall portion to said peripheral surface, said cartridge being configured to be suspended by said flange in the brewing chamber of the apparatus, the piercing member of the apparatus being arranged to apply a force in said longitudinal direction to said piercable portion of said lid to pierce said lid when said cartridge is suspended within the brewing chamber to introduce a hot liquid into said cup-shaped body, said polymer of said first cylindrical sidewall portion forming a barrier deterring the passage of the hot liquid through said first cylindrical sidewall portion and directing the flow of the hot liquid to said second cylindrical sidewall portion to cause said second cylindrical sidewall portion to expand radially outward unconstrained by the brewing chamber to facilitate the mixing of the hot liquid and said beverage brewing ingredient within said cartridge and permit said brewed beverage to exit therefrom. 2. The single brew beverage cartridge of claim 1 wherein said filter comprises heat sealable filter paper having a filtration layer formed of coarse long fiber pulp and a sealing layer form of a polymer. 3. The single brew beverage cartridge of claim 2 wherein said lid comprises primarily paper. 4. The single brew beverage cartridge of claim 3 wherein said primarily paper lid comprises a thin coating of polyethylene. 5. The single brew beverage cartridge of claim 4 wherein said thin coating of polyethylene is rendered biodegradable through the use of an additive. 6. The single brew beverage cartridge of claim 3 wherein said single layer of paper or paperboard comprising a multitude of paper fibers. 7. The single brew beverage cartridge of claim 6 comprising a cover disposed over said lid and said filter to prevent the ingress of air and moisture into said beverage brewing ingredient. 8. The single brew beverage cartridge of claim 7 wherein said cover is removable prior to the suspension of said cartridge in the brewing chamber of the apparatus. 9. The single brew beverage cartridge of claim 8 wherein said cover comprises a bag. 10. The single brew beverage cartridge of claim 9 wherein plural of said cartridges are disposed is said bag. 11. The single brew beverage cartridge of claim 1 wherein said single layer of paper or paperboard comprising a multitude of paper fibers. 12. In combination a single brew beverage cartridge and a beverage brewing apparatus, said single brew beverage cartridge being compostable and biodegradable and comprising a filter, a beverage brewing ingredient, and a lid, said lid comprising a piercable portion, a flange and a collar, said collar comprising a sidewall having a peripheral surface projecting downward from said flange and extending about a longitudinal axis and being resistant to flexure when a force is applied to said lid in a direction parallel to said longitudinal axis, said filter comprising a cup-shaped hollow body holding said beverage brewing ingredient therein, said lid sealing said beverage brewing ingredient in said cup-shaped hollow body, said cup-shaped hollow body being formed of a single layer of paper or paperboard having a slightly tapering cylindrical sidewall and a generally planar bottom wall, said cylindrical sidewall having first and second cylindrical sidewall portions, said first cylindrical sidewall portion being located above said second cylindrical sidewall portion, said second cylindrical sidewall portion having a lower end terminating at said generally planar bottom wall, said second cylindrical sidewall portion and said generally planar bottom wall providing a substantially large surface area through which a brewed beverage can pass, said cylindrical sidewall portion comprising a polymer welding said first cylindrical sidewall portion to said peripheral surface, said beverage brewing apparatus comprising a brewing chamber, a supply of a hot liquid, and a piercing member, said cartridge being configured to be suspended by said flange in said beverage brewing chamber, said piercing member being arranged to apply a force in said longitudinal direction to said piercable portion of said lid to pierce said lid when said cartridge is suspended within said brewing chamber to introduce a hot liquid into said cup-shaped body, said polymer of said first cylindrical sidewall portion forming a barrier deterring the passage of said hot liquid through said first cylindrical sidewall portion and directing the flow of said hot liquid to said second cylindrical sidewall portion to cause said second cylindrical sidewall portion to expand radially outward unconstrained by said brewing chamber to facilitate the mixing of said hot liquid and said beverage brewing ingredient within said cartridge and permit said brewed beverage to exit therefrom. 13. The combination of claim 12 wherein said filter comprises heat sealable filter paper having a filtration layer formed of coarse long fiber pulp and a sealing layer form of a polymer. 14. The combination of claim 13 wherein said lid comprises primarily paper. 15. The combination of claim 14 wherein said primarily paper lid comprises a thin coating of polyethylene. 16. The combination of claim 15 wherein said thin coating of polyethylene is rendered biodegradable through the use of an additive. 17. The combination of claim 14 wherein said filter body is formed of a layer of paper comprising a multitude of paper fibers. 18. The combination of claim 17 comprising a cover disposed over said lid and said filter to prevent the ingress of air and moisture into said beverage brewing ingredient. 19. The combination of claim 18 wherein said cover is removable prior to the suspension of said cartridge in the brewing chamber of the apparatus. 20. The combination of claim 19 wherein said cover comprises a bag. 21. The combination of claim 20 wherein plural of said cartridges are disposed is said bag. 22.
