Abstract
A capsule comprising beverage ingredients therein, and including a closed enclosure hermetically sealed to gas; and a perforated flow-regulating disc member which is arranged in the closed enclosure, perpendicularly to the liquid flow path inside the capsule, and which is configured for separating the ingredients at least partially into at least two ingredient spaces and which enables liquid to spread more evenly and transversely across one ingredient space and to the periphery of the enclosure to facilitate extraction of the beverage ingredients in the ingredient spaces. The capsule also may include an insert located within the enclosure and having tubular portions which are respectively open away from the center of the enclosure, wherein the insert is centrally arranged inside the capsule, and the ingredients are entirely provided radially outside the tubular portions of the insert.
