摘要

A system for preparing a beverage includes an exchangeable capsule, an apparatus including a receptacle for holding the exchangeable capsule, and a fluid dispensing device for supplying a fluid to the exchangeable capsule. The exchangeable capsule includes a circumferential wall, a bottom, and a lid. The wall, bottom and lid enclose an inner space including the extractable product. The receptacle includes bottom piercing means for piercing an entrance area of an alternative capsule for creating an entrance opening for supplying the fluid to the extractable product. The entrance area of the capsule includes an entrance filter for supplying the fluid to the extractable product therethrough. The filter is a multi-layer filter including at least a first layer and a second layer bonded together. The first layer has a higher tear strength than the second layer and the second layer has a higher stiffness than the first layer.
