Definitions

  • the present invention relates to a capsule for the preparation of a beverage according to the preamble of claim 1.
  • capsules for beverage preparation in particular for the preparation of coffee are known from the prior art.
  • FIG. 1 shows the EP 1 908 706 A2 a capsule, in the interior of which an insert part is arranged, which together with the bottom of the capsule body fulfills a valve function, so that after the elimination of a fluid pressure, no more beverage can escape from the capsule.
  • a post-labyrinth structure calms the beverage flow and mixes the prepared beverage.
  • a capsule for the preparation of a drink to be made available which can be easily and inexpensively manufactured.
  • a dripping of the capsule after completion of the preparation process should be prevented as possible or prevented altogether.
  • a frothing of the drink and in the preparation of coffee crema by generating shear forces to be made possible.
  • An inventive capsule for the preparation of a beverage comprises a preferably rotationally symmetrical capsule body which completely or partially limits a substance chamber for receiving at least one substance, a preferably centrally arranged outlet nozzle with an outlet opening and a lid for closing the substance chamber.
  • a liquid can be introduced into the substance chamber and discharged through the outlet opening.
  • a slit valve which in particular continues to open under an increasing liquid pressure in the substance chamber is arranged such that the slit valve opens directly into the outlet nozzle and in particular generates a beverage jet. Under atmospheric pressure, the slit valve is not necessarily tightly closed, at least not airtight.
  • valve which in particular completely opens only under increasing fluid pressure, premature leakage of the beverage can be prevented, which in particular allows a pre-brewing of a coffee substance. Accordingly, the capsule will not only allow a dropwise dispensing of the beverage but, by design, will allow for continuous beverage dispensing.
  • the valve With the design of the valve as a slit valve is achieved that with the same cross-sectional area increased shear in the drink is achieved.
  • an improved crema is produced especially in the production of coffee.
  • the fact that the slit valve opens directly into the outlet the delivery of the beverage is simplified. If the outlet nozzle is cylindrical and in particular has straight inner walls, the dripping time after finishing the preparation can be reduced.
  • the slit valve may be part of an input-side boundary wall of the outlet nozzle.
  • the entire length of the outlet nozzle can be used to calm the beverage jet.
  • the drink will accordingly flow out of the capsule and can be collected in a cup.
  • the slit valve can extend over the entire diameter of the outlet nozzle.
  • Such a slit valve opens up further degrees of freedom with regard to the construction.
  • the slit valve comprise a movable or a deflecting wall element, which is not only separated from the outlet nozzle by the slot of the slit valve, but by further constructive measures, the deflection is simplified.
  • further weakening zones may be provided in the edge region of the boundary wall.
  • the slit valve may be formed by mutually offset wall sections. Through such wall sections, which for example each half of the boundary wall forming, which are arranged offset, an injection molding implementation is easily possible. Thus, a slot can be formed, which can be arbitrarily thin. It is even possible to easily produce a closed valve with a predetermined breaking point. Likewise, it is possible in the injection molding production with a forced removal that the valve is necessarily open from the beginning.
  • the slit valve may be configured such that it opens only when a minimum fluid pressure is reached.
  • a minimum fluid pressure could for a capsule to the system "Tassimo®” greater than 0.5 bar, preferably greater than 1.0 bar, particularly preferably 1.5 bar.
  • this minimum internal pressure can be between 3 and 4 bar.
  • Such a valve ensures, for example, that only a beverage can escape from the capsule when it is under a pressure required for the shearing action in the valve. Accordingly, the quality of the prepared drink, especially the crema during a coffee preparation can always be kept the same.
  • the slit valve can be designed to be self-closing, such that it closes automatically when there is no fluid pressure or when the fluid pressure is reduced below a predetermined pressure. For example, it is conceivable that falls below a pressure of 0.2 bar, the valve gradually closes. Thus, for example, the pressure can be continuously reduced independently of the capsule or machine system before a complete closure takes place.
  • a self-closing valve causes after completion of the preparation process, the capsule no longer drips.
  • the slit valve may be designed as a predetermined breaking point and sealed before an initial application of the minimum liquid pressure tight, in particular fluid-tight, preferably aroma-tight.
  • Such a dense, in particular aroma-tight construction of the slit valve makes it possible that no additional membrane has to close the outlet opening and nevertheless a loss of aroma of the beverage substance can be prevented.
  • the lid and the capsule body are designed accordingly, the quality of the prepared drink can be ensured even after prolonged storage of the capsule.
  • the slit valve may be arranged such that the beverage jet pours transversely to an outlet direction of the outlet nozzle.
  • the outlet direction extends from the slot valve to the outlet opening and is generally approximately parallel to a longitudinal axis of the outlet nozzle and / or approximately parallel to an axis of symmetry of the preferably rotationally symmetrical capsule body.
  • a beverage jet which pours transversely to the outlet direction in the outlet support, will bounce against a side wall of the outlet nozzle, so that on the one hand its flow velocity is reduced and on the other hand, a mixing of the beverage is favored with air.
  • an air inlet opening connected to an air supply duct can be arranged such that the beverage jet can be conducted past the air inlet opening.
  • Such a construction is used for example in the EP 1 440 910 A1 disclosed.
  • air can be entrained, which then mixes with the beverage jet. Accordingly, an airy liquid need not already be formed in the capsule from the beverage substance to produce a foamed beverage, for example. With a subsequent addition of air in the drink, the proportion of air can be increased.
  • the air inlet opening may be arranged and / or configured such that under normal use of the capsule by gravity no drink can enter the air inlet opening. Accordingly, a machine for preparing the drink is prevented from being accidentally contaminated by a beverage exiting through the air inlet port and the air inlet channel of the capsule.
  • this air inlet opening is dimensioned so small that due to the viscosity the prepared drink this can not get through the air inlet opening.
  • the air inlet opening can be arranged laterally or in the direction of gravity above the beverage jet formed by the nozzle.
  • this lateral or above the beverage jet opening arranged leakage of the drink under gravity is prevented even with a larger air inlet opening. Accordingly, however, the machine for preparing the drink must also be taken into consideration, since this machine determines the orientation of the capsule when used as intended.
  • the outlet can have two, three or more air inlet openings. It has been shown that more air can be introduced into the beverage through a plurality of air inlet openings. Accordingly, more or less foamed depending on the drink.
  • the valve and the air inlet opening may be formed such that when the valve is opened, a venturi nozzle is formed.
  • a venturi nozzle By forming the valve as a venturi nozzle, the entrained air or the air introduced into the beverage can be accurately determined.
  • the term venturi nozzle is understood to mean any arrangement whose entrainment of air is based on the Venturi effect or Bernoulli's law. It is also conceivable that the capsule only has a Venturi nozzle and is dispensed with the valve. This Venturi nozzle may be located in place of the slit valve and inject the beverage directly into the spout.
  • the air supply channel or portions thereof may be due to an interaction of the capsule body with one on the capsule body be formed attached plug.
  • Such a two-part construction of the capsule allows additional degrees of freedom and in particular simplifies a cost-effective production of the capsule.
  • the plug can be attached from the outside to the capsule body.
  • This construction allows further degrees of freedom in the construction of the capsule.
  • an additional part is used in the capsule body, which includes the outlet nozzle.
  • a construction is advantageous in which an additional part is mounted on the side opposite the lid to the capsule body. Accordingly, the tolerance chain on the side of the lid is not affected.
  • the capsule body and the outlet nozzle may be integrally formed.
  • integrally forming the capsule body and outlet nozzle tolerances can be kept very simple, which are needed for example for closing the capsule through the lid. Accordingly, the capsule can be produced inexpensively.
  • the outlet nozzle is a separate component which cooperates with the capsule body and is attached to the capsule body.
  • a filter In front of the slit valve, a filter may be arranged.
  • a filter ensures that no undissolved beverage substance particles are flushed to and / or into the valve and clog it. A correct function of the valve is thus ensured.
  • the outlet with its outlet opening can be closed by the lid.
  • a simultaneous closure of the capsule and the outlet opening increases the hygiene of the capsule. When stored, foreign substances that could contaminate a prepared drink or the machine to prepare the drink can not get into the spout.
  • the cover may also have a recess in the region of the outlet opening. This is particularly useful in a flavor-tight design of the slit valve. Also in a two-piece construction of capsule body and outlet nozzle tolerance problems can be avoided if the lid does not have to close the capsule body and the spout.
  • the capsule body and possibly also the outlet nozzle and / or the plug and / or the insert part can be manufactured by an injection molding or deep-drawing process.
  • the use of an injection molding process provides great flexibility with regard to the design of the shape of the capsule body and / or the outlet nozzle and / or the plug and / or the insert part. Although this is limited in a deep drawing process, but it is thus possible to produce especially oxygen and / or aroma-dense capsules. However, oxygen and / or aroma resistance is not limited to deep-drawn capsules.
  • the capsule is formed oxygen-tight, penetration of oxygen into the capsule during storage of a substance contained therein is substantially avoided. As a result, aging of the substance, for example of coffee powder, can be avoided by oxidation.
  • An oxygen-tight capsule is usually also aroma-tight. Accordingly, a leakage of in The substance contained flavor substance during storage thereof within the capsule substantially prevented. Oxygen or aroma resistance is required in order to achieve a minimum shelf life of 12 months, preferably 18 months, especially in the case of coffee.
  • an oxygen- and / or aroma-tight capsule is understood as meaning a capsule in which coffee powder can be stored at atmospheric temperature at room temperature for at least 12 months, preferably 18 months, without the coffee powder changing which impairs the quality of a coffee beverage made therefrom.
  • the film material used for this purpose can have an OTR (Oxygen Transmission Rate) of less than 5, preferably less than 2.
  • OTR Oxygen Transmission Rate
  • the OTR indicates the amount of oxygen diffused per unit of area and time through a film, in the unit: cm3 / m2 / day / 0.21 bar.
