Abstract:
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.
