Definitions

  • the invention relates to the field of systems for preparing beverages by means of liquid introduced into a beverage capsule.
  • it relates to a portion capsule containing a soluble food substance from which a beverage or beverage ingredient can be prepared by injecting water.
  • the so-called coffee capsule systems are known (they are also available in variants for the preparation of tea), in which hot water is generally introduced under pressure into a capsule to prepare a drink, for example by extraction ,
  • Capsules are also known which are compatible, for example, with coffee capsule systems but which contain a soluble substance instead of an extractive material, for example milk powder to prepare a beverage ingredient or beverage.
  • the capsule according to one aspect of the invention forms an outer cup with lid and with a chamber formed in the interior of the cup with the soluble substance.
  • a capsule central axis extends between the lid and cup base, that is, for example, substantially perpendicular to the lid.
  • the cups and lids may be substantially rotationally symmetric about the central axis, with other, for example, cubic, capsule shapes not being excluded.
  • the capsule has an injection element, which the chamber to the cover side or the Cup bottom side limited and which has at least one injection port which is formed so that through it conveyed liquid is injected in a jet in the chamber, in a plane through the central axis and at an angle to the central axis (ie not parallel to this) runs.
  • the injection opening can be arranged near the central axis (for example by not more than 20% of the capsule diameter measured perpendicularly to the central axis at the level of the relevant injection opening) and / or can be designed such that the jet runs in the plane to the central axis So injected to the middle.
  • a plurality of such injection openings may be present, which fulfill in particular all the said condition that the jet generated by them each extends in a plane passing through the central axis and at an angle to the central axis.
  • a plurality of liquid jets can be directed away from one another or toward one another.
  • the capsule is then also suitable for horizontal beverage preparation modules (ie modules in which the capsule is guided with the central axis approximately parallel to the horizontal), regardless of the orientation of the capsule about its central axis, since it can be ruled out that, for example, only a jet down or just a jet upwards and so areas do not come into contact with the water.
  • horizontal beverage preparation modules ie modules in which the capsule is guided with the central axis approximately parallel to the horizontal
  • a substantially laminar vortex does not arise, as in the prior art, but a turbulent flow arises inside the capsule. It has been found that a particularly good mixing between liquid and soluble substance can be effected thereby.
  • the procedure is particularly efficient if there are several injection openings, especially if they are directed in different directions.
  • the injection element is designed as a separate element from the cup and the lid, so that an injection space is formed between the capsule lid and the injection element or alternatively between the capsule bottom and the injection element.
  • an outwardly sealed lid can be present, which can be pierced for introducing the liquid, as is known per se from beverage preparation capsules ago.
  • the injection element is formed by the lid or the cup bottom.
  • the discharge of the drink may additionally or alternatively a piercing - on the corresponding opposite side - assume.
  • the chamber may optionally also have towards the other side - ie towards the bottom or lid - a separate from the cup and the lid screen element which limits the chamber to the injection element opposite side.
  • the angle of the beam to the central axis may be plus or minus 63 ° -68 °, for example about 65 °, 66 ° or 67 °. It has been found that at such angles - the range can be defined as 45 ° -75 °, especially 55 ° to 70 ° - the mixing effect is particularly good.
  • the injection openings are generally small, for example, their diameter is between 0.5 mm and 2 mm, in particular about 1 mm, so that with the customary in beverage preparation machines injection pressures of, for example. 5-15 bar results in a rich beam in the desired direction.
  • FIG. 2 is a Schilittdarwolf of the capsule with partially schematically illustrated elements.
  • FIG. 3 is a view of the injection element from above.
  • FIG. 4 shows a section along the plane A-A in FIG. 3.
  • the capsule 1 according to FIGS. 1 and 2 has a cup 2 and, for the sake of clarity, a cover 4, not shown in FIG. 1 (see FIG. 2).
  • Cup and lid can be made of plastic in a conventional manner; However, on capsules made of other materials, such as aluminum, the invention is applicable.
  • the attachment of the lid on the cup has also been made in a known manner, for example. By ultrasonic welding ssen or possibly by gluing.
  • the cup 2 designed as an insert injection member 3 is fixed.
  • the attachment of the insert to the cup can be accomplished via a positive connection (eg. With groove or other undercut structures in the cup), via a frictional connection (clamping) and / or via an adhesive connection (welding, bonding).
  • the injection element 3 is provided on the side of the lid and limits the filled with the soluble substance (milk powder or similar) chamber 8 to the side of the lid, in Fig. 2 so upwards. Between the cover 4 and the injection element 3, an injection chamber 5 is formed.
  • the capsule can optionally be a sieve element 1 1 be present, which the chamber 8 to the other side - in Fig. 2 downwards - limited, is permeable to the drink and is shown in Fig. 2 only very schematically and dashed.
  • a collecting area 12 is formed between the sieve element 11 and the bottom (or in inverted arrangements the lid), from which the beverage is derived from the capsule.
  • the injection element 3 which is shown in more detail in FIGS. 3 and 4, has a cone-shaped projection 6 protruding toward the capsule interior and central with respect to the central axis 10.
  • a perforation tip injecting the water is taken up, without the injection element being damaged, provided that the introduction of the liquid takes place via such.
  • the injection directions each form an angle ß of 120 ° to each other, which are thus distributed uniformly in the circumferential direction.
  • the angle ⁇ to the cover plane (the angle to the central axis is corresponding to 90 ° -a) is just under 25 °, and the diameter of the injection openings 7 is about 1 mm.
  • FIG. 4 also shows an optional folded-over edge region 9, which can be elastically deformed radially inwards and can serve to fasten the injection element 3 in the capsule cup.
  • the illustrated injection element is configured so that the injection ports are centrally located with respect to radial directions, i. in the vicinity of the central axis 10 and that the beams generated by them run away from each other.
  • Such an arrangement is obtained without restriction when attaching the injection openings 7 in the projection 6.
  • the injection openings are arranged peripherally, and an arrangement may be an option in which the jets toward each other, extending in the direction of the central axis.
