  • the invention further relates to a method for preparing beverages by making use of such an assembly. Diverse capsules for use in a device for preparing beverages are known in the prior art.
  • These capsules generally comprise a housing at least partially filled with a substance for extraction, such as ground coffee beans, which housing is provided with a perforable supply side for injecting water into the housing and provided with a discharge side located a distance from the supply side for the purpose of discharging liquid injected into the housing.
  • the housing is also provided here with a laterally protruding flange which functions as engaging edge to enable mechanical clamping of the capsule in a capsule holder of the device for preparing beverages.
  • Two types of capsule can be distinguished here which can be applied in two respective types of device for preparing beverage.
  • a first type of capsule is formed by a capsule wherein the engaging edge is positioned on or close to the discharge side of the housing and wherein a discharge foil is connected to the engaging edge and thereby closes the discharge side of the housing substantially medium-tightly.
  • the supply side of the housing also takes a closed form through application of a wall part integrally connected to a side wall of the housing.
  • An example of this first - exit clamping - type of capsule is for instance described in EP0512468.
  • the capsule is clamped in the capsule holder, wherein the supply side is perforated. By then pressing water (and air) into the capsule the discharge foil will bulge outward and be perforated by perforation means forming part of the capsule holder.
  • a second type of capsule is formed by a capsule wherein the engaging edge is positioned on or close to the supply side of the housing and wherein a supply foil is connected to the engaging edge, whereby the supply side is closed substantially medium-tightly.
  • a discharge side is closed by a deformable discharge wall which forms an integral part of the housing and which is initially located within a volume enclosed by the housing and which, under the influence of internal pressure build-up as a result of water injection into the capsule, will bulge outward and will deform beyond a volume enclosed by the housing, wherein the discharge side will be perforated by perforation means forming part of the capsule holder.
  • An example of this second - entrance clamping - type of capsule is described in WO9207775.
  • a drawback of this capsule is that the deformable discharge wall must on the one hand be strong enough to be able to prevent unintentional premature opening of the discharge wall, while the discharge wall must on the other hand be sufficiently weak to enable deformation and to enable perforation by the perforation means forming part of the capsule holder. Finding a balance between the two extremes is not found to be simple in practice, which generally also makes the process of producing such a capsule more difficult.
  • the dimensioning and shaping of the known capsule of the second type, and particularly of the deformable discharge wall thereof must also be wholly determined beforehand so that correct operation of the capsule can be guaranteed, this limiting the freedom in design of such a capsule of the second type.
  • An object of the invention is to provide an improved capsule of the second entrance clamping type.
  • the invention provides for this purpose a capsule of the type stated in the preamble, comprising: a housing at least partly filled with a substance to be extracted and/or dissolved, such as ground coffee, wherein the housing is provided with a supply side for pressing a liquid such as water into the capsule, and with a discharge side located at a distance from the supply side for the purpose of discharging liquid provided with extract and/or dissolved substance and guided though the capsule, a laterally protruding engaging edge connected to the housing to enable clamping of the capsule on or close to the supply side of the housing in a device for preparing beverages; at least one perforable supply foil initially covering the supply side of the housing; at least one perforable discharge foil initially covering the discharge side of the housing; and a perforation structure coupled to the housing and provided with at least one perforation element facing toward the discharge foil for perforating the discharge foil, the perforation structure being positioned substantially on a side of the discharge foil remote from the housing, wherein perforation of the discharge foil is caused by deformation of the
  • a perforation plate conventionally forming part of the device is no longer required.
  • the advantage hereof is that the prepared beverage no longer has to be pressed through the conventional perforation plate of the device but can optionally be delivered directly from the capsule to a drinking cup. This can drastically reduce the beverage residue left behind in the device, this being advantageous from a hygiene viewpoint and reducing the required maintenance on the device. It is moreover possible in this way to prevent, or at least counter, beverage pressed out of the capsule mixing with beverage residues coming from one or more already used capsules and already present in the device, whereby the taste of the beverage to be prepared can be guaranteed as fully as possible.
  • the construction of the perforation structure can further be wholly adapted to the beverage to be prepared by means of the capsule, whereby the aeration and taste intensity of the beverage can be regulated, which enhances the final taste sensation for the user.
  • the perforation structure will generally be provided here with one or more throughflow channels or throughfeed openings extending between a side of the perforation structure facing toward the foil and a side of the perforation structure remote from the foil.
  • the particular advantage here is that the number of throughflow channels to be applied and the dimensioning of these throughflow channels can be wholly adapted to the nature of the beverage to be prepared, wherein the intensity of the aeration, the extent of the pressure buildup and the swirling of the beverage pressed out of the capsule can be regulated, which can considerably enhance the taste sensation during consumption of the beverage.
  • the freedom of design in respect of the construction of the perforation structure as such thus makes it possible to fill the capsule with various types of substance, such as ground coffee, tea, cocoa, milk powder and so on.
  • the foil will be perforated by the generally pointed perforation elements and will be pressed during use against the perforation structure, a filtering action will be realized, whereby solid constituents such as coffee dregs can be kept in the housing.
  • the supply side will otherwise generally take a closed form initially, wherein the discharge side will be perforated in the device during use. It is also possible to envisage the supply side already being pre-perforated during the production process, whereby further perforation in the device can be dispensed with.
  • the drawback hereof is however that the capsule generally has to be packaged in order to enable a sufficiently long shelf-life of the substance, and therefore of the capsule.
  • the capsule can optionally be filled with an inert gas, such as nitrogen or carbon dioxide, in order to further increase the shelf- life of the substance.
  • an inert gas such as nitrogen or carbon dioxide
  • the result hereof is that a slight overpressure of several hundred millibar will generally be present in the capsule. This overpressure can possibly increase to some extent if coffee powder, which naturally generates a limited amount of gas, is received in the capsule.
  • the substance received in the housing is preferably in direct contact with the supply foil and the discharge foil, and the housing is thus preferably not provided with a separate internal filter or other intermediate material layer in order to allow the maximum volume of the housing to be used for filling with the substance.
  • the perforation structure and/or the housing is provided with a substantially annular dam which substantially encloses a side of the perforation structure remote from the discharge foil.
  • This protruding annular dam has two functions.
  • a first function of the dam is to create a receiving space for receiving perforation means optionally forming part of the capsule holder, wherein the dam will support on at least one side, preferably at an outer end, on the capsule holder. It is in this way possible to prevent the perforation means which form part of the capsule holder piercing the capsule and coming into contact with the substance held by the capsule. It is however also possible here to envisage the perforation means which form part of the capsule holder engaging on and optionally co-acting with the perforation structure forming part of the capsule, as will be further elucidated hereinbelow.
  • the height of the dam is at least 3 millimetres and the internal diameter of the dam at least 27.5 millimetres. Such a dimensioning will be sufficient to allow use of the capsule in standardized devices in which a capsule of the second (entrance clamping) type can be applied.
  • a second function of the annular dam is to create a guide element for beverage delivered by the capsule, wherein the beverage stream is particularly converged (concentrated), which can considerably facilitate collection of the beverage in a drinking cup. This is particularly the case when the capsule according to the invention is applied in a capsule holder which takes a fully open form on a discharge side and is thus not provided with perforation means, whereby the beverage can be collected in a drinking cup directly from the capsule.
  • the dam can form an integral part of the housing or of the perforation structure.
  • the housing can be manufactured from diverse materials, including an aluminium and/or plastic, particularly polypropylene (PP).
  • PP polypropylene
  • the housing will generally be manufactured from a laminate of a plurality of plastic layers such as PP and ethylene vinyl alcohol (EVOH).
  • An outer (external) material layer can optionally be manufactured from a sealing, particularly elastic material to enable sealing of the capsule in the capsule holder.
  • an aluminium housing it is generally also usual to laminate the aluminium with one or more additional layers, including a protective lacquer coating in order to avoid direct contact of aluminium with the beverage to be prepared, and including for instance a PP layer to enable realization of an (ultrasonic) welded connection to the foil.
  • Each foil generally also comprises aluminium which is optionally provided on one or two sides with a PP layer in order to facilitate one or two-sided adhesion of the foil. It is also possible to envisage the foil comprising aluminium oxide (ALOX), optionally laminated with plastic such as polyethylene terephthalate (PET), whereby an exceptionally thin foil can be obtained with a thickness in the order of magnitude of several microns.
  • ALOX aluminium oxide
  • PET polyethylene terephthalate
  • the supply foil is generally connected by means of welding and/or adhesion to the engaging edge, in particular to a flange forming part of the housing.
  • the discharge foil will generally also be connected by means of welding and/or adhesion to the housing, and particularly to an (internal) flange forming part of the housing.
  • the perforation structure usually takes a plate-like form in order to limit the volume taken up by the capsule.
  • the perforation structure is preferably positioned at least partially in a volume enclosed by the dam, if applied.
  • the advantage hereof is that the external dimensioning of the housing need not be adapted to the standard dimensioning of a capsule and capsule holder, this being advantageous from an economic point of view. It is advantageous here for the perforation structure to connect substantially seamlessly to the housing, wherein the perforation structure can even form an integral part of or be integrally connected to at least a part of the housing.
  • a suitable material for a perforation structure is plastic, such as for instance PP or polyethylene (PE).
  • the engaging edge generally comprises at least one laterally protruding flange connected integrally to the housing. It is also possible to envisage the flange being chemically and/or mechanically connected to an inner side and/or outer side of the housing.
  • the engaging edge will usually be constructed in laminated manner from at least one flange connected to the housing and a sealing element connected to the flange to enable substantially medium-tight clamping of the capsule in a capsule holder.
  • the perforation structure and the housing are manufactured from separate parts, it is recommended that the perforation structure and at least a part of the housing facing toward the perforation structure be manufactured from the same material, such as from polypropylene, to enable realization of a reliable mutual connection.

  • thermoplastic polypropylene-based elastomer to be applied are described in EP0770106 and EP0472946.
  • Such thermoplastic polyolefins are commercially available under the brand names Hifax®, in particular Hifax® 7334 XEP, Adflex®, in particular Adflex® X500F, and Softell®.
  • the perforation structure is provided with a plurality of throughfeed channels for discharging liquid, which throughfeed channels extend from a side of the perforation structure facing toward the foil to a side of the perforation structure remote from the foil.
  • the perforation structure is generally also provided with a plurality of perforation elements. It is possible here to envisage at least a number of throughfeed channels being located a distance from the perforation elements. It is however also possible to envisage, and even advantageous, that at least one perforation element is provided with one or more throughfeed channels. It is found particularly advantageous in practice to apply a conical perforation element through which extend three throughfeed channels which debouch in the cone wall, whereby blocking of the throughfeed channels by perforated foil parts can be prevented.
  • the perforation elements must be sufficiently sharp to be able to perforate the discharge foil. It is therefore advantageous that at least a number of perforation elements take a pointed, in particular pyramid-shaped and/or cone-shaped form.
  • a cone-shaped (conical) shape is generally recommended above a pyramid-shaped embodiment, since the conical embodiment has a periphery varying less pronouncedly as seen in the height of the perforation elements, whereby the discharge foil will tear and/or deform more gradually and therefore more easily.
  • An edge part of the perforation structure facing toward the discharge foil is generally provided with one or more perforation elements for realizing an edge perforation in the foil.
  • the perforation element can here form a cutting edge which can extend over the whole or partial edge part of the perforation structure.
  • the discharge foil initially engages under bias on at least one perforation element. This is because sufficient pressure buildup in the housing of the capsule will, as a result of the bias, result relatively quickly in perforation of the discharge foil.

  • the perforation structure can here even form an integral part of the housing.
  • the perforation structure being displaceable from a first position, in which the foil is substantially intact, to a second position in which the at least one perforation element perforates the foil, whereby discharge of liquid from the capsule is possible.
