Abstract: The invention relates to a capsule for delivering a drink by injecting a pressurized fluid comprising a body (2), an injection wall (3), a chamber (4) containing a bed of food substance to be extracted, means for retaining the internal pressure (5) in the said chamber. The improvement consists in the provision of an injection space (7) allowing a means of injecting fluid in the form of at least one jet of fluid to be introduced through the injection wall and in providing a means (6) for breaking the jet of fluid and distributing the distribution of fluid at a reduced speed across the surface of the bed of substance. These means may adopt various forms such as that of a rigid or flexible perforated wall, or a layer of discrete elements or a spongy layer. Such a capsule improves the flow of liquid extract through the pressure retaining means (5) and improves the extraction conditions.

Abstract: A sealed capsule for containing an ingredient is provided with at least one essentially rigid inner jet direction-diverting member being arranged close to the inner side of a face of the capsule. The inner jet direction-diverting member is designed to divert the direction of at least a portion of a water jet injected through an opening produced in the face. The invention further proposes the dynamical profiling of inner channels in at least one face of the capsule by pressing the face of the capsule against a profiling member of the beverage production device.

Abstract: 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.

Abstract: Device for preparation of a drink from a food substance contained in a capsule (6) comprising a fluid supply unit (5) comprising fluid supply means (50); a capsule holder (4) configured to receive a capsule (6). The capsule holder is removable from the fluid supply unit and can comprise a fluid injector (70) for inserting fluid into the capsule.

Abstract: A method for producing a beverage or liquid comestible from a single capsule by subdividing the interior of the capsule into a plurality of compartments, at least two compartments containing beverage-forming ingredients, introducing a liquid into one of the compartments of the capsule and starting to produce and drain a first beverage component on the basis of the ingredient contained in the first compartment, and opening a fluid communication between the first and the second compartment such that after the start of the production of the first beverage compartment, a production of a beverage component on the basis of the ingredient contained in the second compartment commences. The capsule is preferably used to make cappuccino-style beverages.
