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 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 configured to be directly disposed within the brewing chamber, said cartridge comprising a filter, a beverage brewing ingredient, and a lid, said lid comprising a pierceable 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 flexure resistant to resist flexure when a force is applied to said pierceable 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 formed of a single layer of paper having a slightly downwardly tapering cylindrical sidewall and a generally planar bottom wall, said cylindrical sidewall having first and second cylindrical sidewall portions, said first cylindrical sidewall portion comprising a polymer and being located above said second cylindrical sidewall portion, said first cylindrical sidewall portion being configured to impede the flow of a liquid through said first cylindrical sidewall portion and to direct the flow of that liquid to said second cylindrical sidewall portion, said cylindrical sidewall and said generally planar bottom wall providing a substantially large surface area through which a brewed beverage can pass, 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 pierceable 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 hollow body 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 to effectively brew a beverage within said cartridge and permit said brewed beverage to exit therefrom. 2. The single brew beverage cartridge of claim 1 wherein said lid comprises a polymer. 3. The single brew beverage cartridge of claim 2 wherein said polymer comprises polylactic acid. 4. The single brew beverage cartridge of claim 2 wherein said polymer extends downward from said flange at least approximately 10 mm to approximately 30 mm. 5. The single brew beverage cartridge of claim 1 wherein said first cylindrical sidewall portion is welded to said collar by said polymer. 6. The single brew beverage cartridge of claim 1 additionally comprising a cover disposed around said filter to prevent the ingress of air and moisture into said beverage brewing ingredient. 7. The single brew beverage cartridge of claim 6 wherein said cover comprises a bag. 8. 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 comprising a filter, a beverage brewing ingredient, and a lid, said cartridge being configured to be directly disposed within the brewing chamber, said lid comprising a pierceable portion, a flange and a collar, said collar having a peripheral surface projecting downward from said flange and extending about a longitudinal axis, said lid being flexure resistant to resist flexure when a force is applied to said pierceable 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 and having a cylindrical sidewall formed of a layer of paper, said layer of paper comprising a multitude of paper fibers, said lid sealing said beverage brewing ingredient in said cup-shaped hollow body, said cylindrical sidewall having a first cylindrical sidewall portion and a second cylindrical sidewall portion, said first cylindrical sidewall portion comprising a polymer welding said first cylindrical sidewall portion to said peripheral surface of said collar, said polymer of said first cylindrical sidewall portion being configured to impede the flow of a liquid through said first cylindrical sidewall portion and to direct the flow of such liquid to said second cylindrical sidewall portion, said second cylindrical sidewall portion extending downwardly from said first cylindrical sidewall portion and being configured for permitting a brewed beverage to exit said cartridge through said second cylindrical sidewall portion, said cartridge being arranged 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 pierceable portion of said lid to pierce said lid when said cartridge is suspended within the brewing chamber to introduce a hot liquid into said cartridge 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 to effectively brew a beverage within said cartridge and permit said brewed beverage to exit therefrom. 9. The single brew beverage cartridge of claim 8 wherein said polymer extends downward from said flange at least approximately 10 mm to approximately 30 mm. 10. The single brew beverage cartridge of claim 8, wherein said cylindrical sidewall terminates at a lower end in a general planar, circular bottom wall, said cylindrical sidewall and said bottom wall providing a substantial large surface area through which a brewed beverage can pass. 11. The single brew beverage cartridge of claim 10, wherein said filter is formed of a single layer of paper. 12. The single brew beverage cartridge of claim 8, wherein said filter is formed of a single layer of paper. 13. The single brew beverage cartridge of claim 8 wherein said lid is formed of-a material comprising a polymer. 14. The single brew beverage cartridge of claim 13 wherein said polymer comprises polylactic acid. 15. The single brew beverage cartridge of claim 8 additionally comprising a cover disposed around said filter to prevent the ingress of air and moisture into said beverage brewing ingredient. 16. The single brew beverage cartridge of claim 15 wherein said cover comprises a bag.
