Capsule insert able in a beverage production device for preparing a beverage from a substance contained in the capsule by introducing liquid in the capsule and passing liquid through the substance using centrifugal forces for producing the beverage which is centrifuged peripherally in the capsule relatively to a central axis of the capsule corresponding to an axis of rotation during the centrifuging operation comprising: an enclosure containing a predetermined amount of beverage substance, a cup-like shaped body, an upper wall for closing the body, wherein it comprises a flange-like rim extending outwardly from the body which comprises an annular raising portion forming a restriction for the centrifuged liquid How path when said portion is engaged by a pressing surface of the beverage production device.

1. A method of using a capsule, the method comprising: inserting into a beverage production device a capsule comprising an enclosure containing an amount of beverage substance, a cup-like shaped body comprising a sidewall, an upper outer wall closing the cup-like shaped body, and a rim extending out
1. A method of using a capsule, the method comprising: inserting into a beverage production device a capsule comprising an enclosure containing an amount of beverage substance, a cup-like shaped body comprising a sidewall, an upper outer wall closing the cup-like shaped body, and a rim extending outwardly from the cup-like shaped body, the rim comprising an annular raising portion that extends from a top surface of the rim and in a direction opposite to a bottom of the body and that is a force-setting portion of a valve, the beverage production device comprising a plate comprising a pressing surface portion of the valve;applying a resilient load from a resilient member onto the plate to engage the pressing surface portion with the force-setting portion, the annular raising portion being rigid to resist compression by the pressing surface portion applying a closure force thereto;forming orifices in the upper outer wall in a perforable peripheral area of the upper outer wall by perforating elements;preparing a beverage from the beverage substance contained in the capsule by introducing liquid in the capsule and passing the liquid through the beverage substance, the preparing of the beverage comprising using centrifugal forces to produce the beverage, wherein the liquid is centrifuged in a centrifuged liquid flowpath in which the liquid is moved peripherally in the capsule relative to a central axis of the capsule corresponding to an axis of rotation during the use of the centrifugal forces, and engagement of the pressing surface portion with the force-setting portion forms a restriction for the centrifuged liquid flowpath; andforcing the valve to open by the pressing surface portion of the valve being pushed against the resilient member by the centrifuged liquid that is exiting through the orifices and moving away from the annular raising portion for creating a flow restriction gap while the annular raising portion remains of a relatively constant dimension to restrict the centrifuged liquid flowpath through the restriction gap. 2. The method of claim 1, wherein the annular raising portion extends in a direction opposite to a bottom of the cup-like shaped body. 3. The method of claim 1, wherein the annular raising portion extends a certain height (“d”) from a relatively flat annular inward portion of the rim merging with the sidewall. 4. The method of claim 3, wherein the annular raising portion creates an increased thickness (“d+d1”) on the relatively flat annular inward portion. 5. The method of claim 3, wherein the relatively flat annular inward portion forms a sealed portion for the upper outer wall. 6. The method of claim 1, wherein the annular raising portion extends in a direction substantially perpendicular to a transversal plane of extension of the rim. 7. The method of claim 1, wherein the annular raising portion is made integral with the rim. 8. The method of claim 1, wherein a lower surface of the rim merging with the sidewall of the cup-like shaped body is free of any projection in a direction opposed to the annular raising portion. 9. The method of claim 1, wherein the annular raising portion extends from a top surface of the rim, and the rim comprises an annular groove on a bottom surface directly opposed to the annular raising portion. 10. The method of claim 1, wherein the annular raising portion is embossed in the rim. 11. The method of claim 1, wherein the cup-like shaped body comprises a material selected from the group consisting of aluminum, plastics, and combinations thereof. 12. The method of claim 1, wherein the annular raising portion is a separate element and attached to the rim. 13. The method of claim 12, wherein the annular raising portion is made of rubber elastic material. 14. The method of claim 1, wherein the annular raising portion comprises a gas vent. 15. A method for using a capsule in a beverage production device, the method comprising: applying a resilient load from a resilient member onto a plate comprising a pressing surface portion of a valve to engage the pressing surface portion with a force-setting portion of the valve, the plate provided by the beverage production device, the capsule comprising an enclosure containing an amount of beverage substance, a cup-like shaped body comprising a sidewall, an upper outer wall closing the cup-like shaped body, and a rim extending outwardly from the cup-like shaped body, the rim comprises an annular raising portion that is the force-setting portion of the valve, wherein the annular raising portion extends in a direction opposite to a bottom of the cup-like shaped body, the annular raising portion being rigid to resist compression by the pressing surface portion applying a closure force thereto wherein the capsule comprises a relatively flat annular inward portion of the rim merging, at one end, to the annular raising portion extending of a certain height therefrom, and, at an opposite end, to the sidewall of the cup-like shaped body;forming orifices in the upper outer wall; andpreparing a beverage from the beverage substance contained in the capsule by introducing liquid in the capsule and passing the liquid through the beverage substance, the preparing of the beverage comprising using centrifugal forces to produce the beverage, wherein the liquid is centrifuged in a centrifuged liquid flowpath in which the liquid is moved peripherally in the capsule relative to a central axis of the capsule corresponding to an axis of rotation during the use of the centrifugal forces, and engagement of the pressing surface portion with the force-setting portion forms a restriction for the centrifuged liquid flowpath; andforcing the valve to open by the pressing surface portion of the valve being pushed against the resilient member by the centrifuged liquid that is exiting through the orifices and moving away from the annular raising portion for creating a flow restriction gap while the annular raising portion remains of a relatively constant dimension to restrict the centrifuged liquid flowpath through the restriction gap. 16. The method of claim 1, wherein a first end of the resilient member is fitted into a base that abuts the plate, and a second end of the resilient member is connected to a screw element; and the method further comprises adjusting the resilient member by rotating the screw element. 17. The method of claim 1, wherein the resilient member is positioned on the central axis of the capsule. 18. The method of claim 9, wherein the annular groove matches a shape of the annular raising portion.
