A method for producing a portion capsule () is proposed, wherein, in a first step, a base element (), having a capsule bottom (″), a capsule wall (') encircling the capsule bottom (″), and a flange () encircling the capsule wall (′) are produced in a forming process, wherein, in a second step, a beverage raw material is filled into a capsule interior () bordered by the capsule bottom (″) and the capsule wall (′), and wherein, in a third step, a capsule cover (), closing the capsule interior (), is fastened to the flange (), characterized in that, after the third step, a bead () encircling the capsule wall (′) is impressed into the flange (),

Method for producing a portion capsule

A portion capsule for preparing a beverage in a beverage preparation machine, the portion capsule including a base element with a cavity for receiving a beverage raw material, and a capsule cover sealing the cavity; the base element including a capsule base, a peripheral flange with a peripheral bulge, and a capsule wall extending between the capsule base and the peripheral flange; the capsule cover attached to the flange along a sealing plane; a sealing element in the form of a sealing bead pointing away from the capsule cover on the flange; the sealing plane extending along the flange on the side of the capsule cover, between the bulge and the sealing bead; and the sealing bead including an inner flank on the capsule wall side and an outer flank on the bulge side, both oriented at an angle of 80 to 90 degrees to the sealing plane.

A method for producing a cartridge system for producing a beverage, where the cartridge system is insertable into a beverage preparation machine and has a cartridge with a reservoir filled with a beverage substance and a cartridge receptacle connected to the cartridge. The cartridge receptacle has a mixing chamber and a fluid feed opening into the mixing chamber. An aluminum sheet is provided in a first step. A main body is generated at least partially from the aluminum sheet by punching and either deep-drawing or impact extrusion in a second step. A sealing element is attached to the main body in a third step. The main body is connected to the cartridge receptacle in a fourth step.

Cartridge system and method for producing a cartridge system

The invention relates to a cartridge system () for producing a drink in a drink preparation machine, comprising a cartridge () that has a reservoir () filed with a drink substance (), and a cartridge receiver () that can be reversibly connected to the cartridge, said cartridge receiver () comprising a mixing chamber () and a cartridge discharge device () which causes at least partial transfer of the drink substance () from the reservoir () into the mixing chamber (), and said cartridge receiver () comprising a fluid supply () which opens into the mixing chamber (). The invention also relates to the cartridge receiver () of the cartridge system (), the drink preparation machine, and the corresponding method for producing a drink ().
