Abstract:
Capsules for use in a beverage production machine. One capsule includes a base body having a flange-like rim and containing beverage-forming ingredients therein, the ingredients being sealed in the base body by a foil member attached to the flange-like rim, and at least one flow control porous member arranged between at least a portion of ingredients in the capsule and the foil member. Another capsule includes a first wall member for supporting beverage-forming ingredients, a second perforable wall member attached to the first wall member, and at least one porous layer located between the beverage-forming ingredients in the capsule and the second wall member, with the porous layer forming a multilayer laminate with the perforable non-porous foil member. These flow control porous members provide faster and more consistent flow of the liquid extract through the capsule and significantly reduces the resurgence of non-soluble solids.
