Abstract: A portion capsule base body defines a directed axis and is fillable with an extraction material. The base body has a bottom region, a circumferential side wall adjoining the bottom region and having an outer surface, an a circumferential collar region adjoining the side wall, and through which an opening is defined. The axis is centrally extending through the bottom region and through the opening, and defines an axial direction pointing from the bottom region through the opening. A distance measured perpendicular to the axis is referred to as the axial distance, and the side wall has at least one ramp element by which at least one ramp region is defined in which the axial distance of the outer surface is increasing along the axial direction.

Abstract: A method for operating a drinks preparation machine, for producing a total product amid the use of a portion package, and according to a preparation prescript. The method includes detecting a portion code of a portion package by way of a portion recognition unit; determining first preparation parameters of the preparation prescript that are assigned to the portion code and are stored in the drinks preparation machine, and determining second preparation parameters of the preparation prescript, wherein at least one of the first and/or the second preparation parameters is an adaptable preparation parameter, and at least one preparation parameters is not adaptable; detecting a user input for adapting at least one adaptable preparation parameter; and preparing the total product according to the preparation prescript with at least one adapted preparation parameter.

Abstract: A drinks preparation machine for preparing brewed drinks from a portion package with an extraction material includes a water tank, a pump, a water heater and a brewing chamber for receiving the portion package. The pump delivers water from the water tank into the brewing chamber via the water heater. A temperature sensor measures a temperature along the fluid path including an initial temperature at the location of the temperature sensor at least in one operating condition after a switching-on procedure or waking-up procedure and before a possible heating-up procedure of the water heater, and, after the water heater has reached an operating temperature, to carry out a rinsing procedure of the brewing chamber with water from the water heater, when and only when the measured initial temperature corresponds to a certain condition, and only subsequently to effect an introduction of the portion package into the brewing chamber.

Abstract: A system for preparing a brewed product, the system including a portion capsule containing an extraction material, and an extraction appliance for preparing the brewed product from the extraction material contained in the portion capsule. The extraction appliance has an injection device for introducing a brewing liquid into the portion capsule and an extraction device for driving an extraction product out of the portion capsule. The injection device and the extraction device define between them an accommodation space for the portion capsule. The extraction device has a pressure device, by which a wall of the portion capsule inserted in the accommodation space, which wall faces toward the extraction device, can be pressed in toward the capsule interior in order to compact the extraction material contained in the portion capsule before the injection device introduces brewing liquid into the portion capsule.

Abstract: A method for producing a capsule includes providing a plastic main body having a bottom region, a peripheral side wall, and a peripheral main-body collar adjoining the peripheral side wall, wherein the main body has a substantially rectangular cross-section in the region of the main-body collar; providing a deep-drawn plastic cover for closing the capsule, wherein the cover forms an outward curvature, which adjoins a peripheral cover collar; filling the main body with an extraction material; and placing the cover onto the main body such that the cover collar lies on the main-body collar and fastening the cover collar to the main-body collar via ultrasonic welding. The cover is provided with an energy-director, which focuses the ultrasound energy during the ultrasonic welding, and wherein the cover has at least one groove that extends peripherally on an outer face in the region of the cover collar.

Abstract: A portion capsule that is filled with an extraction substance for producing a brewed product, and includes a main part and a cover. The main part has a base region and a peripheral lateral wall. The cover is secured to the main part along a peripheral collar. The collar is connected to the peripheral lateral wall toward a cover side. The main part has a substantially rectangular cross-section in the region of the collar. The cover forms an outward curvature such that the cover contributes to a capsule volume, and the collar is at least 1.6 mm wide.

Abstract: The invention relates to a coffee machine for brewing a hot drink, in particular, a coffee drink, by means of a portion capsule with a capsule lid and a capsule base, comprising a pressurized water device, a portion capsule holder and a controller. The portion capsule holder is provided with two relatively-displaceable puncture means, which pierce the capsule lid and the capsule base on or after insertion of the portion capsule in the portion capsule holder, such that hot water can enter the portion capsule through the capsule lid and the drink escapes through the capsule base from the portion capsule. The controller is provided for the provision of three differing pressures for the pressurized water, for example, for brewing espresso, white coffee and filter coffee. The capsule base of the portion capsule can comprise a pre-weakened spot.

Abstract: A device for preparing froth, in particular for preparing milk froth by means of hot steam output by a domestic coffee machine, contains an elongate nozzle body having a rear end and a front end, which can be connected in the region of its rear end to a hot steam source and which has an outlet nozzle in the region of its front end. A casing sleeve having a rear end and a front end surrounds the nozzle body and has an air intake opening in the region of its rear end and an outlet opening in the region of its front end, an intermediate space being formed between the nozzle body and the casing sleeve. An outer sleeve surrounds the casing sleeve at least in the region of the rear end of the casing sleeve.
