Abstract
A sealed capsule for use in apparatus including a capsule receiving station and a water delivery system for brewing a hot beverage in which a hot liquid under pressure infuses a material. A capsule base has a concave bottom floor with angularly spaced structural ribs that form channels for directing brewed beverage to a sharpened spout. A collar surrounds the dispensing spout. A foil attaches to the collar to overlie the spout. A filter lies on the structural ribs. Infusible material lies on the filter. A water distribution plate overlies the infusible material. A cover closes the base unit and includes a water inlet. As the capsule seats in the capsule receiving station, the foil seal is forced over the sharpened spout to rupture and enable brewed beverage to be dispersed. A probe of the water delivery system also penetrates the cover to direct water into the capsule without contacting the infusible material or the brewed beverage.
