Abstract
A beverage filter cartridge comprises an outer container with an access opening. A filter element is received in and configured and arranged to subdivide the interior of the container into first and second chambers. A beverage medium is stored in the first chamber. A lid closes the access opening. The lid has a first section overlying the first chamber and a second section overlying the second chamber. The first section of the lid is yieldably piercable to accommodate an inflow of liquid into the first chamber for infusion with the beverage medium to produce a beverage. The filter element is permeable to accommodate a flow of the beverage from the first chamber into the second chamber, and the second section of the lid is yieldably piercable to accommodate an outflow of the beverage from the second chamber to the exterior of the cartridge.
