Definitions

  • the present invention relates to a capsule for preparing a liquid food according to the preamble of claim 1.
  • Capsules in particular are often used for the preparation of various hot drinks, especially coffee or tea, in home use.
  • Such capsules which are designed as disposable products, usually comprise a capsule body, which forms a receiving space for the beverage ingredients, and a lid covering the capsule body.
  • the ingredients are mostly roasted and ground coffee powder, but sometimes also dried tea leaves.
  • soluble products in general or concentrates can also be used.
  • water under pressure is passed through the capsule, which causes the material contained in the chamber to be extracted or dissolved.
  • the EP 1 440 913 A1 a capsule that is suitable for holding various beverage ingredients.
  • Said capsule consists of essentially air and water impermeable materials.
  • the capsule comprises a capsule body which forms a receiving space for the beverage ingredients.
  • an outlet nozzle is held in the receiving space by a support means acting on the base of the capsule.
  • both the receiving space and the outlet nozzle are closed with a cover covering the capsule body.
  • the lid is penetrated in two places at the same time; On the one hand for introducing pressurized water into the chamber, on the other hand to open the outlet nozzle.
  • the problem with said capsule is that the support means for holding the outlet connection runs through the receiving space and thus reduces its usable volume. This is particularly disadvantageous when larger portions of beverage ingredients are required, for example for the simultaneous production of several cups of coffee or a particularly strong coffee beverage, which requires large amounts of coffee powder.
  • the capsule should be inexpensive and can be produced in large quantities.
  • the capsule for the preparation of a liquid food comprises a preferably rotationally symmetrical capsule body with a side wall and with a base, in particular in one piece with it.
  • the capsule comprises a lid covering the capsule body to form a receiving space for at least one starting substance for the preparation of the liquid food.
  • To discharge the liquid food from the capsule there is an outlet nozzle with a Entry opening and an outlet opening held in the capsule body. The outlet nozzle is directed towards the inside of the cover with its outlet opening.
  • the outlet nozzle can be held in the capsule body by at least one support means.
  • the at least one support means engages the capsule body on the side wall, in particular in an edge region, preferably on an inner shoulder or on an inner edge.
  • outlet nozzle can also be fastened to the inside of the lid and thus held in the capsule body.
  • the receiving space extends at least between the inlet opening of the outlet nozzle and the bottom of the capsule body.
  • This configuration of the capsule can prevent the at least one support means from running through the receiving space for the starting substance.
  • the proportion of the total volume of the capsule body which can be used to hold the starting substance can thus be increased.
  • the at least one support means can be designed as a perforated plate covering the receiving space. This enables a liquid introduced through the lid of the capsule to flow through the holes of the perforated plate into the receiving space with the starting substance. The resulting flow resistance is comparatively low. The spout is reliably held in the capsule body by the perforated plate.
  • the at least one support means can also be designed as a valve plate covering the receiving space. An edge of the Valve plate can form mutually contacting valve surfaces with the capsule body in a depressurized state.
  • the design of the at least one support means as a valve plate largely prevents accidental and undesired leakage of liquid from the receiving space through an opening in the lid after the liquid food has been prepared. The outlet nozzle is also held reliably in the capsule body.
  • the at least one support means can also be designed as a plurality of struts, in particular, which run radially. This design eliminates the need to subdivide the capsule body into several compartments, so that the receiving space for the at least one starting substance extends essentially through the entire capsule body. This allows the capsule body to be filled with starting substance up to the lid. The available volume of the capsule body is used accordingly. There is no increase in the flow resistance of a liquid passed through the capsule through the at least one proppant. The spout is still reliably held in the capsule body.
  • the outlet nozzle and the at least one support means can be formed in one piece. This eliminates the problem of creating a reliable connection between the support means and the outlet connection. Furthermore, such a capsule can be produced efficiently and inexpensively.
  • the outlet connection and / or the support means can be connected firmly, in particular in a fluid-tight manner, to the cover covering the capsule body. This can in particular prevent the capsule contents from inadvertently leaking out during food preparation.
  • the outlet nozzle can be closed by the cover covering the capsule body. This makes it possible to store the at least one starting substance for the preparation of the liquid food in a hermetically sealed manner in the receiving space of the capsule body.
  • a filter element can be arranged on the outlet nozzle, in particular at its inlet opening. Such is usually necessary for the preparation of liquid foods by extracting a starting substance. This applies in particular to coffee or tea.
  • An arrangement with the filter element directly at the inlet opening of the outlet nozzle is advantageous in that no further fluid-carrying elements for guiding the filtrate to the outlet nozzle are necessary. As a result, a larger proportion of the total volume of the capsule body can be used as a receiving space for the at least one starting substance.
  • the filter element can cover the inlet opening of the outlet connection and have an area of 200 to 1000 mm 2 , preferably 400 to 800 mm 2 , preferably 500 to 700 mm 2 . It has been shown that such a surface area is particularly advantageous in the case of capsules which are provided for producing a single portion of a coffee beverage. This can be justified by the fact that such a dimensioning of the filter element represents a good balance between its space requirement within the capsule body and the flow resistance caused by it.
  • the filter element can be designed as a fleece, perforated film or filter plate. These are filter types that are used in the manufacture of beverages, particularly in the manufacture of coffee drinks. In addition, these are inexpensive to manufacture and can therefore be used in disposable capsules.
  • the filter element can be supported by a support structure. The use of a support structure effectively prevents the filter element from bursting due to the occurrence of a pressure gradient during a filtration.
  • an inlet in particular an inlet channel
  • an inlet nozzle can be arranged inside the capsule body and directed in the direction of the lid covering the capsule body.
  • the inlet if necessary additionally, as an inlet nozzle.
  • the presence of an inlet makes it possible to better control the introduction of a liquid into the receiving space of the capsule body. With an inlet trough, for example, the distribution of the liquid over the entire capsule content can be better achieved.
  • the presence of an inlet nozzle makes it easier to establish a tight fluid connection between a food production device and the capsule.
  • the inlet can be closed with the cover covering the capsule body.
  • 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 in particular be arranged essentially in one plane. So that can attach of the lid on the capsule body are carried out by conventional methods as are customary for sealing food packages.
  • the outlet nozzle can be arranged centrally and the inlet in an edge region of the capsule body. This is particularly advantageous since, in practice, extraction or dissolution of the capsule contents from the outside in has proven to be advantageous.
  • the capsule body can be manufactured by an injection molding or a deep-drawing process and in particular can be made oxygen and / or aroma-tight. If the capsule is made oxygen-tight, penetration of oxygen into the capsule during the storage of a starting substance contained therein is essentially avoided. Aging of the starting substance, for example coffee powder, by oxidation can thereby be avoided. An oxygen-tight capsule is usually also aroma-tight. Accordingly, the escape of flavoring substances contained in the starting substance is essentially prevented during the storage thereof within the capsule. Oxygen or aroma tightness are required in order to achieve a minimum shelf life of twelve months, preferably eighteen months, especially with coffee.
  • an oxygen and / or aroma-tight capsule is understood to mean a capsule in which coffee powder can be left in atmospheric air for a period of at least twelve months, preferably at least eighteen months, without the coffee powder being changed which would affect the quality of a coffee beverage made from it.
  • the film used for this has an OTR (Oxygen Transmission Rate) of less than 5, preferably less than 2.
  • OTR indicates the amount of oxygen per unit area and time that diffuses through a film, in the unit: cm 3 / m 2 / day / 0.21 bar.
  • the capsule body and optionally also the outlet nozzle and / or the holding means can be made of a single or multi-layer plastic, preferably containing polyepropylene. It is a material that has proven itself for the production of food packaging. In addition, polypropylene can be easily processed by injection molding.
  • the present invention further relates to a food preparation system comprising a capsule as described above and a food preparation device.
  • a capsule body 2 for a capsule 1 comprises a side wall 3 which is formed in one piece with a bottom 4.
  • the capsule body 2 forms a receiving space 6 for at least one starting substance for the preparation of a beverage.
  • the capsule body 2 has in one Edge area 11 on an inner shoulder 12, on which a support means 10 can engage.

  • a liquid is introduced into the capsule 1 through the inlet trough 23, it can pass between the cover 5 and the perforated plate 14 to the holes 25 and flow into the receiving space 6 via these.
  • the large number of holes 25 provided ensures a uniform distribution of the liquid introduced into the capsule 1 over the entire receiving space 6.
  • the introduced liquid passes through the two filter elements 19 and 19 'in succession in order to reach the outlet port 7 via the inlet opening 8.
  • the second filter element 19 ' is supported with the support structures 20, which is clear from the enlargement of the partial area A in Figure 7 can be seen.
  • the inlet opening 8 is designed as a cream slot 28.
  • the liquid In order to flow into the outlet nozzle 7, the liquid must pass through the cream slot 28, which causes the latter to foam.
  • the lid 5 is penetrated between the outlet nozzle 7 and the circumferential collar 26 by an annular penetration element provided on a beverage production device. As a result, the finished drink can be derived from the capsule 1.
  • the capsule body 2 of an alternative embodiment of a capsule 1 according to the invention does not have an inner shoulder 12 but an inner edge 13. Together with the side wall 3 of the capsule body 2, this forms an inlet gutter 23.
