  • the pressure in the capsule may be more reproducible from one capsule to another.
  • the quality of the prepared beverage may be approximately more constant from capsule to capsule. Beverage prepared with a capsule according to the invention may have an improved quality and may be more reproducible from one capsule to another capsule.
  • the filter layer comprises a layer of non-woven and/or woven material wherein the filter layer comprises at least one first region where the non- woven and/or woven material has been sealed to prevent egress of liquid there through, and at least one second region where the non-woven and/or woven material has not been sealed to allow egress of liquid there through
  • the entrance filter layer may add to a reproducible pressure development in the capsule. Also, by providing a filter at the entrance area, it may be avoided that extractable product is spilled from the capsule at the bottom, e.g. due to the high pressure.
  • Non-woven fibrous material is understood to comprise fibres and/or filaments that can be relatively long and/or relatively short, but that are arranged in a rather chaotic way in the material. No preferred orientation of the fibres and/or filaments and/or no arrangement and/or organisation of the fibres and/or filaments are present in the material.
  • An example of a non-woven fibrous material is Tyvek®.
  • Paperlike material can be seen as a non-woven material comprising fibres in a chaotic, non-preferential arrangement.
  • Woven fibrous material is understood to comprise fibres and/or filaments that can be relatively long and/or relatively short.
  • the fibres and/or filaments are woven.
  • Commonly known woven material may comprise fibres and/or filaments in a first direction that are crossed by fibres and/or filaments in a second direction, for example transverse to the first direction.
  • Knitted fiber material may in the context of this invention also be understood to be woven material.
  • Both filter layers of non- woven and woven fibrous material have advantageous elastic characteristics, i.e. they are relatively inelastic in the plane of the filter layer. In the plane of the layer, the filter layer may not stretch too much such that openings in the layer may approximately remain undeformed when under tension e.g. due to pressure in the capsule.
  • the non-woven and/or woven material comprises polymeric fibres, such as polypropylene or polyethylene.
  • polymeric fibres such as polypropylene or polyethylene.
  • the non-woven and/or woven filter layer may be less susceptible to deformations due to the fluid pressure.
  • the non- woven and/or woven material may comprise biodegradable fibres, such as paper fibres.
  • the walls of the capsule may e.g. be made from biodegradable material, with a biodegradable filter, the complete capsule may be biodegradable. After use, the consumer may throw away the biodegradable capsule e.g. in a special compost container.

  • the filter layer of non-woven and/or woven material may be recyclable as well.
  • the walls of the capsule and/or the entrance layer and/or the exit layer may be provided from metal for example for a re-usable capsule, e.g. when the capsule can be refilled by the user.
  • the non-woven and/or woven filter layer and/or the capsule can e.g. be provided from dishwasher-proof fibrous material.
  • the filter layer is a multi-layer filter comprising a further layer, wherein the further layer is a perforate and/or porous layer.
  • the non-woven and/or woven filter layer may become stronger and more resistant to the high fluid pressure.
  • the further layer with perforations and/or porosity, fluid can flow through the filter layer in the exit and/or entrance area.
  • the layers are bonded together to give one another additional strength and/or stiffness.
  • the further layer may be of a non-woven and/or woven material
  • the filter layer may be a multi-layer filter in a relatively easy and cost-effective way.
  • the layers are bonded together to give one another additional strength and/or stiffness.
  • the layers are bonded together over approximately the entire first regions.
  • the second regions mainly overlap between the multiple layers to allow a passage for the fluid.
  • the second regions of the filter layer where the non-woven and/or woven material has not been sealed to allow egress of liquid there through, may be distributed over substantially the entire surface of the filter layer.
  • By distributing the Openings' over substantially the entire surface of the filter layer an approximately even pressure distribution may be reached over the filter layer to allow an approximately uniform pressure development over the entrance area of the capsule. It may be possible to concentrate the openings in a centre area of the filter layer, and to leave the peripheral edge of the filter layer free from openings.
  • the openings and/or perforations of the further layer correspond with the second regions of the layer of non-woven and/or woven material to allow fluid passing there through.
  • the receptacle comprises bottom piercing means intended for piercing the entrance area of an alternative capsule for creating at least one entrance opening for supplying the fluid to the extractable product through said at least one entrance opening.
  • the capsule of the system according to the invention is arranged such that the entrance area of the capsule comprises an entrance filter for supplying the fluid to the extractable product there through which entrance filter, in use, is positioned at a distance from the bottom piercing means, such that the capsule of the system is not pierced by the bottom piercing means and the bottom stays intact.
  • the receptacle comprises lid piercing means intended for piercing the exit area of an alternative capsule when the exit area sufficiently presses against the lid piercing means under the influence of the pressure of the fluid and/or beverage in the capsule for creating at least one exit opening through which the beverage can drain from the alternative capsule.

  • the exit filter 36 may be a filter layer comprising a layer of a non-woven and/or woven fibrous material, wherein the filter layer comprises at least one first region where the non- woven and/or woven material has been sealed to prevent egress of liquid there through and at least one second region where the non-woven and/or woven material has not been sealed to allow egress of liquid there through.
  • the exit filter 36 may deform against the lid piercing means, but it may not tear, rupture or be pierced by the lid piercing means.
  • the exit filter 36 may not deform under influence of fluid pressure in the capsule, so the dimensions of the second regions remain approximately the same, i.e. less than 3% deviation during use. Due to the non-woven and/or woven material, a stable exit filter 36 may be provided that may stay intact under influence of the pressure. Sufficient pressure may be developed in the capsule 2 for a good quality beverage. Moreover, due to the non- woven and/or woven layer, the exit filter may be sufficient strong and sufficient stiff, the pressure development may be reproducible from one capsule to another, thereby improving the reproducibility of the brewed beverage.
  • the exit filter 36 is adapted to the lid piercing means 128 such that the capsule 2, in use, is not pierced by the lid piercing means 128 and the lid 16 stays intact. More in general it applies that the exit filter 36 and the lid piercing means 128 are adapted to each other such that the capsule 2, in use, is not pierced by the lid piercing means 128 and the lid 16 stays intact.
  • the lid piercing means 128 are shown having sharp toothed points intended for piercing the lid. It will be appreciated that, alternatively, the lid piercing means 128 may have blunt piercing surfaces, e.g. as indicated with dashed lines in Fig. 1. In such embodiment, an alternative capsule may, nevertheless, be pierced by the blunt piercing means 128, e.g. when the lid of the alternative capsule consists of a sheet of aluminium foil.
  • Parameters such as the non-woven and/or woven material, the distribution and/or plurality of the first and second regions, the stiffness and/or strength, of the exit filter of the capsule 2 of the system according to the invention can be chosen such that the exit filter 36 may not to be pierced or torn.
  • the parameters of the exit filter may be chosen to suit these blunt piercing means.
  • the exit filter may e.g. be thinner than when the lid piercing means are sharp, while guaranteeing that the exit filter has the sufficiently high tear strength and/or forming the sufficiently low flow resistance not to be pierced or torn.
  • the lid piercing means comprise ridges against which the lid, in use, abuts.
  • Such ridges may be formed by the blunt piercing means 128 as shown with dashed lines in Fig. 1.
  • the ridges may e.g. form at least 10%, possibly at least 25% of the portion of the surface of the receptacle 106 which, in use, coincides with the portion of the surface area of the lid 16 overlying the second, end 18.
  • the lid 16 may be supported by the ridges over, e.g. at least 10%, preferably at least 25%, of the portion the surface area of the lid 16 overlying the second, open, end 18.
  • the lid of an alternative capsule may be pierced by such ridges
  • parameters of the exit filter 36 of the capsule 2 of the system 1 according to the invention may easily be chosen such that the exit filter has the sufficiently high tear strength and/or sufficient stiffness not to be pierced or torn.
  • the exit filter may be sufficiently strong and/or sufficiently stiff such that the exit filter only abuts against the top surfaces of the ridges, and does not deform until the bottom between the ridges. Deformation of the exit filter is thus limited. It will be appreciated that when the lid piercing means comprise ridges, the parameters of the exit filter may be chosen to suit such lid piercing means.
  • the ridges comprise edges which are not sharp.
  • a radius of curvature of the edges is approximately 50 ⁇ m, although other radii are conceivable, such as 100, 200 or 500 ⁇ m.
  • the prior art alternative capsule may, nevertheless, be pierced by the blunt piercing means 128, e.g. when the lid consists of a sheet of aluminium foil.
  • the parameters of the exit filter 36 may be chosen to suit such lid piercing means. Parameters of layers of the exit filter 36 of the capsule 2 of the system according to the invention can be chosen such that the exit filter 36 may not be pierced or torn.
  • the ridges of the lid piercing means 128 have a convex top against which the lid 16 abuts. Hence, when the lid, in use, is pressed against the ridges, the surface area over which the lid is supported by the ridges increases, thus reducing the local pressure exerted on the lid by the ridges. Thus it is possible to provide, in an easy manner, that the lid, in use, does not tear and/or rupture and stays intact.
  • the exit filter 36 forming an exit area of the capsule 2, through which the beverage, here coffee, can drain from the capsule, is formed by a filter layer of non-woven and/or woven material, such as filter paper, comprising at least one first region where the non-woven and/or woven material has been sealed to prevent egress of liquid there through, and at least one second region where the non-woven and/or woven material has not been sealed to allow egress of liquid there through.
  • the non-woven and/or woven material may comprise polymeric fibres, such as polypropylene or polyethylene.
  • the non- woven and/or woven material may also comprise biodegradable materials, such as e.g. paper fibres.
  • the entire lid 16 is formed as the exit filter 36.
  • the fluid can drain from the capsule 2 over a large area.
  • a very homogeneous drain of beverage from the extractable product is obtained.
  • the capsule 2 comprises an outwardly extending rim 38 at the second end 18, wherein the lid 16 is attached to the outwardly extending rim 38 and/or an inner surface of the circumferential wall 10, e.g. by gluing, welding or the like.
  • the exit filter 36 is attached to the outwardly extending rim 38.
  • the entrance area is open to allow liquid flowing there through in the capsule 2.
  • the entrance area of the bottom 12 is provided with an entrance filter 34.
  • the entrance filter 34 comprises a filter layer, wherein the filter layer comprises a layer of non-woven and/or woven fibrous material, wherein the filter layer comprises at least one first region where the non- woven and/or woven material has been sealed to prevent egress of liquid there through and at least one second region where the non-woven and/or woven material has not been sealed to allow egress of liquid there through.
  • the capsule 2 comprises an entrance filter 34 which is positioned at a distance from the bottom piercing means 12, such that the capsule 2 is not pierced by the bottom piercing means 122 and the bottom 12 stays intact when the bottom piercing means is brought in the extended position.
  • the entrance filter 34 is provided as the bottom 12.
  • the entrance filter 34 is provided as a separate filter layer that is attached to inwardly extending rims 42 of the bottom 12.
  • the entrance filter layer 34 may also be attached to an inner or outer surface of the circumferential wall 10, and/or to an inner or outer surface of the inwardly extending rims 42 of the bottom 12.
  • parameters of the layers of the exit filter 36 of the capsule 2 of the system 1 according to the invention can be chosen such that the exit filter does not tear or rupture, e.g. having the sufficiently high tear strength and/or having sufficiently high stiffness and/or forming the sufficiently low flow resistance not to be pierced or torn. It will be appreciated that the lid and/or the exit filter may not rupture or being torn by the lid piercing means 128.
  • the exit filter 36 is e.g. made of partly sealed filtering paper
  • parameters of the filtering paper such as density, thickness and/or PE-content, distribution and/or plurality of the first and second regions, can easily be chosen to provide the exit filter having the sufficiently high tear strength and/or forming the sufficiently low flow resistance.

  • the second regions 52 are thus open to allow egress of liquid there through.
  • the fibres in the non-woven material are chaotically provided in the material and do not have a preferential orientation or arrangement.
  • the flow restriction for the liquid is provided by the non-woven filter layer.
  • the non-woven filter layer usually comprises a number of filaments and/or fibres as shown in Fig. 4.
  • the filaments can have different lengths and different sizes and can be provided from different materials.
  • the first regions of the non- woven filter layer can be sealed, e.g. by gluing, painting, melting or a resin.
  • the second regions are left open or can be made open and are not sealed.
  • the second regions may be entirely open, e.g. when the second regions are formed with a hot or cold needle, or filaments and/or fibres of the non- woven filter layer may still be present in the second regions, but then without e.g. resin between the filaments.
  • the second regions do not deform, tear or rupture under influence of the fluid pressure.
  • the second regions may be reinforced at the edges to prevent deformation, tear or rupture of the second regions.
