A system for preparing a predetermined quantity of beverage comprises an exchangeable capsule and a fluid dispensing device for supplying an amount of fluid to the exchangeable capsule, a receptacle for holding the exchangeable capsule, and an outlet arrangement for supplying the beverage to a container, such as a cup. The capsule comprises a circumferential wall, a bottom, a lid, an entrance area and a closed exit area. The circumferential wall, the bottom and the lid enclose an inner space that comprises an extractable product. The fluid dispensing device supplies fluid to the extractable product for preparing the beverage. In use, the outlet arrangement is in fluid communication with the exit area for draining the prepared beverage from the capsule. The capsule further comprises an opening element through the closed exit area for draining the prepared beverage from the capsule.

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; andwherein 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. 2. The system of claim 1, wherein the entrance area is provided in the bottom of the exchangeable capsule. 3. The system of claim 1, wherein the exchangeable capsule comprises a substantially rigid rim that projects towards an outside of the exchangeable capsule from the edge of the circumferential wall. 4. The system of claim 1, wherein the circumferential wall is rigid so that, in use, deformation of the circumferential wall with respect to the receptacle is prevented. 5. The system of claim 1, wherein the receptacle comprises a bottom piercing element configured to pierce an alternative bottom of an alternative capsule for creating at least one entrance opening in the alternative bottom of the alternative capsule for supplying the fluid to the extractable product through said at least one entrance opening; wherein, in use, the bottom of the exchangeable capsule of the system is positioned at a distance from the bottom piercing element such that it is not pierced by the bottom piercing element and stays intact. 6. The system of claim 3, wherein the fluid dispensing device is arranged for supplying the fluid to the exchangeable capsule under a pressure of approximately 4-20 bars. 7. The system of claim 1, wherein the entrance area is formed by an entrance filter comprising entrance openings, wherein the entrance filter is structured as a boundary for the exchangeable capsule such that the entrance filter separates the inner space from an outside environment external to the inner space, wherein the exchangeable capsule further comprises a further opening element formed by the material sealing the entrance openings of the entrance, the material being at least one of partly dissolvable and degradable upon the supply of fluid from the fluid dispensing device, and wherein parameters of the entrance filter are chosen such that the entrance filter does not tear or rupture.
