  • the capsule has an inlet and an outlet opening or is provided with such openings in the corresponding preparation machine. Since the preparation of the liquid food is carried out under pressure, the known capsule systems tend to drip after extraction, which leads to undesirable contamination and favors the nucleation in the preparation machine.
  • the crema and mixed drinks of the foam is not or only insufficiently formed.
  • the US 2010/0047418 , the WO 2009/008723 and the WO 2010/093247 show closed with a lid cup for producing a mixed drink.
  • a lid cup for producing a mixed drink.
  • In the center of a static mixer is arranged, which includes a riser.
  • In a ground-level area openings are arranged on the riser.

  • the initially mentioned EP 1 774 878 A1 relates to a process for the preparation of a beverage from a capsule in a beverage preparation machine.
  • the capsule used has a capsule shell with an ingredient and a filter that limits the ingredient in the shell.
  • an overflow wall is arranged, which channels the extract flowing out of the filter.
  • the GB 2 235 868 A relates to a filter device for the preparation of tea.
  • a siphon is provided in a filter container consisting of an inner outlet tube and a cuff arranged above.
  • the siphon is surrounded by a ring, which is provided in the lower part with passages for retaining tea leaves.
  • the EP 1 500 358 A1 relates to a system for dispensing drinks with different amounts of foam from a capsule.
  • the capsule has a cup and a penetrable lid.
  • the cup has an inner shoulder, on which a membrane is welded. This membrane divides the cup into an upper portion containing the substance to be extracted and a lower portion collecting and discharging the liquid.
  • it is intended to provide a capsule, possibly in a system, which forms turbulence when extracted in the flow, in order to obtain an optimal crema in coffee and an optimal foam in mixed drinks and which drips after extraction of the liquid food reduced or prevented.
  • An inventive capsule for the preparation of a liquid food has a, preferably rotationally symmetrical capsule body with a side wall and a particular integrally formed with this bottom, and a capsule body covering the lid to form a closed chamber.

  • the ground-near transition region is already formed with a plurality of transition openings.
  • This specific embodiment with an outlet pipe and a riser pipe through which flow is in the opposite direction ensures that, after the extraction process has ended, dripping of the extraction material from the capsule is prevented. Furthermore, a shearing action is forced by the transition openings, which is advantageous for the formation of the crema in the coffee preparation or the foam in mixed drinks.
  • the riser can occupy a height between 50% and 100%, preferably between 60% and 90%, particularly preferably between 70% and 80% of the maximum height between the bottom and lid within the capsule. This height of the riser ensures that dripping of the capsule after extraction is effectively prevented.
  • the transition openings may be dimensioned such that they exert a filtering effect for retaining the substance.
  • a filter effect is advantageous, so that the liquid food is free of undissolved substance.
  • transition openings may be dimensioned such that the sum of their cross-sectional areas is smaller than the cross-sectional area of the riser to generate shear forces in the flow. It is thus forced in an extraction, a pressure difference between the chamber and the riser, so that in particular the crema is formed reinforced in the coffee or foam in mixed drinks.
  • the outlet pipe can be arranged within the riser pipe, preferably concentrically. By such a configuration, in particular fewer individual parts are necessary and a simple production of the capsule is made possible.

  • the riser may have an average outside diameter between 20% and 35%, preferably between 22% and 30%, more preferably between 24% and 26% of the mean inside diameter of the capsule. This dimensioning allows a relatively large amount of substance in the capsule can be accommodated and at the same time optimum flow of the liquid food from the chamber through the riser and the outlet pipe can be ensured.
  • the spout or riser may be integrally formed with the bottom of the capsule. Due to the one-piece design of the outlet pipe or the riser pipe to the bottom in particular the number of individual parts of the capsule is reduced. The manufacturing cost of the capsule are thus reduced.
  • a closure element in particular a film, can be arranged between the chamber and the outlet opening, wherein the closure element can be opened for dispensing the liquid food.
  • a closure element can, for example, ensure a fluid-tight and / or aroma-tight and / or oxygen-tight closure of the capsule.
  • an aroma-tight closure is necessary.

  • the bearing element can be arranged in the riser.
  • the bearing element is formed by a flexible membrane, a bellows or a bellows.
  • the penetration means may be formed integrally with the outlet pipe. Such a configuration reduces the number of required individual parts, so that the capsule can be inexpensively manufactured and assembled.

With such a sealing element can be ensured that the liquid food, which from the chamber by the Penetrationsstoff emerges transition openings, flows without leakage in the riser. In particular, contamination of a preparation machine is prevented.
