Claim:
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; and forcing 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.
