Abstract
A coffee capsule is provided, the outer dimensions of which are matched to the size of a filtered-coffee capsule, but which has a separating element that separates an empty area from an extraction-material area. Furthermore, at least one liquid channel is provided, which passes through the empty area for example. The liquid channel or liquid channels and the extraction-material area are designed in such a way that water introduced into the capsule at an injection location or a beverage produced in the capsule substantially does not enter the empty area.
Claims10
A portion capsule, comprising:
- an outer wall, said outer wall enclosing a closed capsule volume by a plurality of outer wall portions integrally connected to one another;
- a separation element, the separation element dividing the closed capsule volume into an extraction material region filled by an extraction material and an empty region not containing any extraction material;
- and
- a plurality of liquid channels, the liquid channels being connected in a liquid tight manner with the separation element and being connected in a liquid tight manner with the outer wall at a liquid channel mouth location;
- wherein the separation element comprises a liquid permeable passage between the extraction material region and the liquid channels but is liquid tight between the extraction material region and the empty region;
- whereby liquid is capable of flowing between
- a liquid channel mouth passage through the outer wall at the liquid channel mouth location,
- and an extraction material region passage through the outer wall from the extraction material region at a second location,
- substantially without entering the empty region, and
- wherein the outer capsule wall is liquid tight at the second location, and wherein the extraction material passage needs to be generated by disrupting the outer capsule wall at second location.
