A portion packaging for receiving a substance to produce a drink. This packaging includes a curved base, a transition region integrally formed in this base, a side wall which is integrally formed on this transition region and extends conically, and an edge which is integrally formed on this side wall and protrudes outwardly. The base, the transition region and the side wall form a cavity for receiving the substance. The cavity has an opening which is closable with a film. A deformable sealing element is arranged on the portion packaging. Also, a device for producing a drink by extraction of same from a substance contained in a portion packaging. |

1. A portion packaging for receiving a substance to produce a drink comprising a capsule having:
a cavity with an opening for receiving a substance and, a side wall at said opening, an outwardly protruding edge which is integrally formed on the side wall at said opening, a film, and a deformable sealing element which is integrally formed with the outwardly protruding edge, wherein said opening is closable by the film and wherein the deformable sealing element comprises a rollover edge having an essentially elliptical or oval cross-sectional shape defining an open interior cavity that facilitates deformation, and having a greater height than width, wherein at least a portion of the rollover edge is configured to be irreversibly deformed when producing the drink, and the rollover edge is integrally formed with a plurality of edge portions on an outer border of the protruding edge, with a first edge portion having a rounded shape and protruding downwards, a second edge portion being integrally formed on the first edge portion such that the second edge portion is arranged essentially at right angles to a surface of the protruding edge, a third edge portion being integrally formed on the second edge portion and having a rounded shape, and a fourth edge portion being integrally formed on the third edge portion with the fourth edge portion extending essentially parallel to the second edge portion and either being connected to the outer border of the protruding edge as said sealing element is deformed or being free-standing when said sealing element is not deformed, the fourth edge portion comprising a free end configured such that deformation of the deformable sealing element surrounds the free end by the four edge portions. |
