Abstract: An adapter (1) for use in the preparation of a beverage by a capsule (2) and a beverage preparation device. The adapter (1) can be placed together with the capsule (2) in the beverage preparation device. The adapter (1) has a capsule face (4), on which mechanism (5) for introducing a liquid into the capsule (2) and mechanism (6) for discharging a liquid from the capsule (2) are located. In addition, the adapter (1) has a device face (7), on which an inlet (8) for a liquid provided by the beverage preparation device and an outlet (9) are located. The inlet (8) is fluidically connected to the mechanism (5) for introducing a liquid into the capsule (2) and the outlet (9) is fluidically connected to the mechanism (6) for discharging a liquid from the capsule (2).

Abstract: The invention relates to a capsule (1) for preparing a beverage, comprising—a core material (3) having a pressed product and—a shell (2) enclosing the core material, the capsule (1) having in a breaking strength test a maximum percentage expansion of at least 15% in a direction transverse to a pressing direction.

Abstract: A set (47), for use in the preparation of a beverage by a beverage preparation device, comprising a capsule (2) and an adapter (1). The adapter (1) and the capsule (2) are interconnected in a stand-by position such that the adapter (1) and the capsule (2) can be transferred, from the stand-by position, into an operating position in which the inlet (8) of the adapter (1) is in fluid connection with the substance chamber (49) of the capsule (2).

Abstract: The invention relates to a capsule for preparing a beverage product. The capsule comprises a capsule body, a lid, and an inlet for introducing a fluid into the capsule. The capsule body is covered by the lid to form a closed receiving chamber, and the inlet is arranged eccentrically on the capsule in relation to a center of the cover. A first machine readable code is eccentrically applied to, in particular printed on, the lid. In relation to the center of the lid, the first machine-readable code. in particular the center thereof, is arranged at an angular spacing relative to the inlet. The angular spacing has a magnitude of at most 70°, preferably at most 60°, preferably at most 50°.

Abstract: An adapter (1) for preparing a beverage by a capsule (2) and a beverage preparation device (3). The adapter (1) has a disk-shaped main body (17) with a capsule side (4) and a device side (7). On the capsule side (4), a mechanism (5) for introducing a liquid into the capsule (2) and mechanism (6) for discharging a liquid from the capsule (2) are arranged. On the device side (7), an inlet (8) and an outlet (9) are arranged. The inlet (8) is fluidically connected to the mechanism (5) for introducing the liquid, and the outlet (9) is fluidically connected to the mechanism (6) for discharging the liquid. The device side (7) is at least partially covered with a covering (67) to form an intermediate volume (19), between the main body (17) and the covering (67), which fluidically connects the inlet (8) to the mechanism (5) for introducing the liquid.

Abstract: The invention relates to a brewing device having two separate brewing chambers, comprising two capsule receptacles and two closure elements for the two brewing chambers, and a gearing for the actuation of the two closure elements, the gearing comprising a common drive element, and two output elements for the two brewing chambers.

Abstract: The invention relates to a beverage preparation machine, particularly a coffee machine, which comprises two brewing chambers for receiving a beverage substrate for extraction, and a valve for switching a liquid supply to the individual brewing chambers, said valve being a membrane valve and comprising an inlet opening for the liquid supply, a first outlet opening for the first brewing chamber, a second outlet opening for the second brewing chamber, and a closing membrane.

Abstract: The invention relates to a device for producing milk froth using steam and air, comprising a convergent-divergent nozzle for achieving a suction effect. A milk feed line is connected to the nozzle in such a way that milk can be drawn from a milk container into a nozzle under the suction effect. The nozzle is designed as a one-piece component created in an injection-molding process and contains a nozzle inlet opening, a nozzle outlet opening, and a milk feed line connection in the form of a milk intake fitting. The air inlet is located before a nozzle inlet opening of the nozzle with regard to the flow direction. A controllable air pump is provided to introduce air into the steam feed line.
