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 portion capsule includes a base element, for example like a cup, having a capsule base and a circumferential side wall. A cover element is attached to the base element and forms together with the same an interior space having an extraction material region filled with an extraction material. A filter element is placed in the interior space. The filter element separates the extraction material region from the capsule base or from a capsule cover formed by the cover element. The filter element is formed of an open pore foam material.

Abstract: A portion capsule having a base element for receiving an extraction product, and a method for producing the portion capsule. The portion capsule has a bottom region and a circumferential side wall, wherein the bottom region and the circumferential side wall form an interior space. At least the circumferential side wall includes a cellulose-based sheet and is formed by a full winding of the cellulose-based sheet about a base element axis.

Abstract: The portion capsule includes an outer beaker with a cover and with a chamber, which is formed in the inside of the beaker and which has a soluble substance as well as a middle axis. Furthermore, an injection element, which delimits the chamber to a cover side or to a base side and which includes at least one injection opening, is also present. The injection opening is designed such that fluid, which is delivered through it in the direction of the chamber, is injected as a jet into the chamber, the jet running in a plane that runs through the middle axis and at an angle to the middle axis.
