Claim:
1. A system for preparing a predetermined quantity of beverage suitable for consumption using an extractable product, comprising: an exchangeable capsule; an apparatus comprising a fluid dispensing device that supplies an amount of fluid to the exchangeable capsule, a receptacle that holds the exchangeable capsule, and an outlet arrangement that supplies the beverage to a container; wherein the exchangeable capsule comprises a circumferential wall, a bottom, a lid, an entrance area, and a closed exit area situated on the lid; wherein the circumferential wall, the bottom and the lid enclose an inner space that comprises the extractable product; wherein the exchangeable capsule further comprises an opening element that is arranged for providing an opening through the closed exit area for draining the prepared beverage from the exchangeable capsule; wherein the closed exit area is formed by an exit filter comprising exit openings; wherein the exit filter of the exchangeable capsule is structured as a boundary for the exchangeable capsule such that the exit filter of the exchangeable capsule separates the inner space from an outside environment external to the inner space; wherein the opening element is formed by a material sealing the exit openings of the exit filter of the exchangeable capsule, the material being at least one of partly dissolvable and degradable upon a supply of fluid from the fluid dispensing device for providing the opening through the exit area; and wherein the system is arranged for bringing the fluid dispensing device in fluid connection with the entrance area for supplying the fluid to the extractable product for preparing the beverage; wherein the system is further arranged so that, in use, the outlet arrangement is in fluid communication with the closed exit area for draining the prepared beverage from the exchangeable capsule; wherein the receptacle is also configured to use an alternative capsule having an alternative exit area; wherein the receptacle comprises a lid piercing protrusion configured to pierce the alternative exit area of the alternative capsule when the alternative exit area is sufficiently pressed against the lid piercing protrusion under an influence of a pressure of the fluid and/or beverage in the alternative capsule for creating at least one alternative exit opening through which the beverage can drain from the alternative capsule; wherein parameters of the exit filter of the exchangeable capsule are chosen such that the lid piercing protrusion and the exchangeable capsule of the system are adapted to each other such that the lid of the exchangeable capsule, in use, is not pierced by the lid piercing protrusion and stays intact such that the exit filter of the exchangeable capsule does not tear or rupture under the influence of pressure of the fluid and/or beverage in the exchangeable capsule.
