摘要：
A method for producing a beverage from an ingredient-containing capsule by inserting a sealed capsule into a capsule enclosure space of a beverage production device, enclosing the capsule by a relative displacement of at least two enclosing members which define the capsule enclosure space, and opening an inlet face of the capsule and injecting a fluid under pressure into the capsule in order to open an outlet face of the capsule. The capsule is provided at its outer surface with sealing material which is exposed to the fluid pressure in the capsule enclosure space. After enclosing the capsule, the fluid pressure in the capsule at least partially acts on the sealing material, such that in turn the sealing material is pressed against one of the enclosing members thus constituting a flow resistance that is sufficient to guarantee a pressure build-up inside the capsule sufficient for the pressure-assisted opening of the outlet face of the capsule.
