Cartridge for the preparation of beverages
First Claim
1. A cartridge containing one or more beverage ingredients and being formed from substantially air- and water-impermeable materials, the cartridge comprising or being adapted to have formed therein at least one inlet and a circumferential manifold for the introduction of an aqueous medium into the cartridge and at least one centrally located outlet, the circumferential manifold surrounding the outlet, and characterised in that flow of the aqueous medium through the cartridge is generally in a radially inward direction from the toward the at least one outlet.

26. A cartridge containing one or more beverage ingredients and being formed from substantially air- and water-impermeable materials, the cartridge comprising:
-
an outer shell having a rim bounding an opening, a sidewall portion attached to the rim, and an upper wall portion attached to the sidewall and spaced from the rim by the sidewall; a storage chamber containing the one or more beverage ingredients, the storage chamber being at least partially bounded by the outer shell; a manifold located at the periphery of the cartridge and substantially surrounding the storage chamber, the manifold having a plurality of openings permitting fluid communication with the storage chamber and the manifold at least partially bounded by the outer shell; an inlet chamber for the introduction of an aqueous medium into the cartridge, the inlet chamber being in fluid communication with the manifold via one or more apertures formed in a wall of the inlet chamber and being at least partially bounded by the outer shell; an outlet surrounded by the manifold; an outlet passage permitting fluid communication between the storage chamber and the outlet; a lid attached to the rim of the outer shell and closing the opening of the outer shell, the lid at least partially bounding the storage chamber, the manifold, the inlet chamber and the outlet passage, the lid being pierceable in use to accommodate an inflow of an aqueous medium into the inlet chamber, and the lid being pierceable in use to accommodate an outflow of beverage formed from interaction of the aqueous medium and the one or more beverage ingredients in the storage chamber; and flow of the aqueous medium through the cartridge, in use, is generally in an inward direction from the inlet chamber to the outlet. - View Dependent Claims (27, 28, 29)
