Definitions

  • the present invention relates to a capsule according to claim 1.
  • capsules are often used at home to prepare different beverages, above all coffee or tea, but also soluble beverages.
  • Such capsules which are designed as single-use products, usually comprise a capsule body, which forms a cavity for receiving beverage ingredients, and a lid closing off the cavity.
  • the beverage ingredients are roasted and ground coffee powder, but sometimes also dried tea leaves.
  • soluble products in general or concentrates can also be used.
  • pressurized water is passed through the capsule, causing the material contained in the capsule to be extracted or dissolved.
  • EP 1 440 911 A1 a capsule which is suitable for receiving various beverage ingredients.
  • Said capsule consists of essentially air and water impermeable materials.
  • the capsule includes a capsule body that forms a compartment for the beverage ingredients.
  • An inner part is held in a stable position in the chamber and has an outlet nozzle for a beverage produced in the chamber.
  • both the chamber and the outlet nozzle are closed with a lid that covers the capsule body.
  • the lid is penetrated in two places at the same time; on the one hand to introduce pressurized water into the chamber, on the other hand to open the outlet nozzle.
  • the lid covering the capsule body is firmly connected to the end faces of the capsule body and the outlet nozzle. If there are any weak points in this connection, pressurized water can potentially leak out of the capsule in an uncontrolled manner. This can be particularly serious when the capsule contents are extracted, since a suspension of beverage ingredients, for example coffee powder, present in the capsule can leave the capsule in an uncontrolled manner. The consequence of this can be contamination of the beverage production device or contamination of the finished beverage.
  • said capsule should be more versatile and easier to produce than the prior art.
  • Such a capsule comprises a preferably rotationally symmetrical capsule body, which forms a cavity with an opening for receiving at least one substance for preparing a liquid foodstuff.
  • an outlet nozzle is arranged inside the cavity, which is directed in the direction of the opening.
  • the outlet nozzle is in particular closed with a cover covering the opening.
  • the capsule body and the outlet nozzle are designed in one piece.
  • the outlet nozzle does not have to be inserted as a separate part into the cavity of the capsule body. Since the capsule body and outlet nozzle are designed in one piece, the precise relative positioning of the outlet nozzle in the capsule body is ensured. When attaching the cover to the capsule, it can thus be achieved more easily that it seals off both the opening of the capsule body and the transition to the outlet connection piece, or possibly the outlet connection piece itself. The risk of the capsule contents escaping before, during or after the beverage preparation is thus considerably reduced.
  • an inlet in particular an inlet channel
  • an inlet nozzle can be arranged inside the cavity and directed in the direction of the opening.
  • the inlet optionally additionally, as an inlet nozzle.
  • the presence of an enema allows better control of the introduction of a liquid into the cavity of the capsule body.
  • an inlet channel for example, the liquid can be better distributed over the entire contents of the capsule.
  • the presence of an inlet nozzle makes it easier to establish a tight fluid connection between a beverage production device and the capsule.
  • the inlet can be closed with the cover, which at the same time covers the opening.
  • both the inlet and the outlet nozzle are arranged on the same side of the capsule.
  • the end faces of the capsule body and the outlet nozzle, and possibly also the inlet, can be arranged essentially in one plane.
  • the attachment of the lid on the capsule body can be done by conventional methods, such as those for Sealing of food packages are common.
  • the outlet nozzle can be arranged centrally and the inlet can be arranged in an edge area of the capsule body. This is particularly advantageous since in practice extraction or dissolution of the capsule contents from the outside inwards has proven to be advantageous.
  • the capsule body forms a transition area and the cavity is in fluid communication with the outlet nozzle via the transition area.
  • the two compartments can be used for other functions.
  • the cavity formed by the capsule body can perform the actual storage function of the capsule, while other processes such as the foaming of the prepared liquid foodstuff through the introduction of air or the mixing of several ingredients take place in the transition area.
  • the transition area is covered with a cover, in particular with a cover element or a cover film, on a side facing away from the opening of the capsule body.
  • a cover in particular with a cover element or a cover film
  • various functions such as a sieve or filter function, can be implemented in the transition area by the covering element.
  • the cover element it is also possible for the cover element to be provided with an inlet nozzle, or for the cover film to be penetrated in order to introduce a liquid. This enables a modular design of the capsule, in which the introduction and dispensing of liquid takes place either on one side or on two sides.
  • the cover can be connected to the capsule body by gluing, ultrasonic welding or heat sealing. These are tried and tested methods that enable the cover to be reliably attached to the capsule body.
  • the cover can be designed as a cover element, in particular as a plug, and can be connected to the capsule body in a non-positive and/or positive manner, in particular via a snap-in connection. These configurations enable the capsule to be assembled very easily.
  • a filter element can be arranged in the transition area. This makes it possible to filter the drink produced during preparation. This is particularly advantageous when preparing coffee. However, the production of tea from dried tea leaves would also be conceivable.
  • the filter element can be disc-shaped and/or made of filter paper.
  • the capsule body and the cover form an annular fluid channel in the transition area.
  • Such a device makes it possible for a prepared liquid foodstuff to be introduced into the outlet connection piece over the entire circumference of the latter.
  • the capsule body and the outlet nozzle, and possibly also the cover, can be manufactured using an injection molding or deep-drawing process.
  • the use of an injection molding process allows great flexibility with regard to the design of the shape of the capsule body. Although this is limited in a deep-drawing process, it is possible to produce particularly oxygen- and/or aroma-tight capsules. However, oxygen and/or aroma tightness is not limited to capsules produced by a deep-drawing process.
  • the capsule is designed to be oxygen-tight, penetration of oxygen into the capsule during storage of a starting substance contained therein is essentially avoided. As a result, aging of the starting substance, for example coffee powder, can be avoided by oxidation.
  • An oxygen-tight capsule is usually also aroma-tight. Accordingly, flavoring substances contained in the starting substance are essentially prevented from escaping during storage of the same within the capsule. Oxygen or aroma impermeability is required in order to achieve a minimum shelf life of 12 months, preferably 18 months, particularly in the case of coffee.
  • an oxygen- and/or aroma-tight capsule is understood to mean a capsule in which coffee powder can be stored at room temperature in atmospheric air for a period of at least 12 months, preferably 18 months, without the coffee powder changing , which impairs the quality of a coffee beverage made from it.
  • 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 per unit area and time that diffuses through a foil, in the unit: cm 3 /m 2 /day/0.21 bar.
  • the finished oxygen- and/or aroma-tight capsule body, or the entire capsule (including cover and lid) can have an OTR (oxygen transmission rate) of less than 5, preferably less than 2. This applies regardless of the manufacturing process used.
  • the capsule body and the outlet nozzle, and optionally also the cover can be made of a single-layer or multi-layer plastic, preferably containing polypropylene. This is a material that has proven itself for the manufacture of beverage packaging. In addition, polypropylene can be excellently processed by injection molding.
  • FIG 1 is a capsule body 2 for a capsule 1 according to the invention (cf. 9 ) shown from its side facing away from the opening 4 with the cavity 3 of the capsule body 2 .
  • the transition area 10 can be seen, which is in fluid connection with the cavity 3 via a number of passages 9, 9'.
  • figure 2 shows the capsule body 2 according to FIG figure 1 from a different perspective.
  • a cover 11 can also be seen, which is designed here as a cover element in the form of a plug.
  • the Figures 3 and 4 also show the capsule body 2 and the cover element 11. However, this time the cover element 11 is inserted into the transition region 10 of the capsule body 2.
  • the outlet connection 5 is arranged centrally in the cavity 3 .
  • the cavity 3 contains an inlet 7, which in the present case is designed as an inlet channel.
  • the passages 9, 9' can be seen, which fluidly connect the cavity with the transition region 10. It can also be seen that the inlet channel 7 is connected to the remaining part of the cavity 3 via a gap 14 .
  • FIG. 6 shows the capsule body according to the Figures 1 to 5 in combination with the cover 6, which completely covers the opening 4 of the capsule body 2 in order to close it.
  • the figure 7 shows one to figure 2 analog figure. However, it can be seen that a filter element 12 is also arranged between the capsule body 2 and the cover 11 within the transition area 10 .
  • Out of figure 8 are more structural details of the capsule with filter element 12 according to figure 7 better visible.
  • the outlet nozzle 5 arranged centrally within the cavity 3 is composed of an inner part 15 and a peripheral collar 16 .
  • the peripheral collar 16 is designed in such a way that its end face 8 ′ lies in one plane with the end face 8 of the capsule body 2 .
  • the fluid-tight attachment of a cover 6 is thus made significantly easier.
  • An air intake hole 17 can be seen between the inner part 15 and the circumferential collar 16 .
  • the air intake hole 17 serves to allow air to be sucked into the transition area 10 as part of the preparation of a liquid foodstuff, as a result of which foaming of the liquid foodstuff dispensed through the outlet nozzle 5 can be achieved.
  • the inlet 7 is designed as a circumferential channel which is connected to the remaining cavity of the capsule body 2 via a gap 14 .
  • the figure 9 shows a fully assembled capsule with a capsule body as previously described. However, for the sake of clarity, the substance for preparing a liquid foodstuff within the cavity 3 has been omitted. It can be seen that the foil 6 is in direct contact with the end faces 8 , 8 ′ of the capsule body 2 and the outlet nozzle 5 . These are connected to each other by an ultrasonic welding process. Alternatively, however, a hot sieve method could also be used.
  • figure 10 is the part marked by a circle figure 9 enlarged. More details about the transition area 10 can be seen.
  • a filter element 12 is attached to the outlet connection piece 5, with which the substance contained in the capsule 1 for the preparation of a liquid foodstuff can be filtered. This is particularly advantageous when producing coffee beverages from ground coffee powder.
