Definitions

  • This invention relates to capsules for containing a substance from which a beverage can be produced.
  • Dolce Gusto (Registered Trade Mark) capsules comprise a capsule body having a frustoconical side wall with a transverse closure wall at the smaller diameter end and a radially outwardly protruding flange encircling the wider end.
  • a filter disc comprising at least a layer of (micro-) perforated weldable plastics material can be inserted into the capsule to keep the coffee in a comprised state.
  • a foil or plastics material disc is secured to the flange to close the filled capsule.
  • the filter disc lies between the charge of coffee and the foil closure disc.
  • To produce the beverage the foil is penetrated by a hollow needle and hot water is forced under pressure into the capsule between the foil and the filter disc.
  • the filter disc has the effect of preventing direct flow of water as a jet from the needle into the coffee. It inhibits flow and causes the hot water to spread out over the whole area of the capsule. This ensures that liquid coffee is extracted from the entire charge.
  • the filter disc further has the disadvantage that because of the arising fluid pressure inside the charge of substance during extraction, a center portion of the flexible filter disc may start to flex away from the charge of substance, giving opportunity to the substance starting to swirl and fines thereof to settle out.
  • EP 1 784 344 shows in its fig. 2 and 3 that for this welding of the direct-flow-preventing filter disc inside the capsule body, a support and welding die need to be used.
  • the support die is dimensioned to have the filled capsule placed therein.
  • the welding die is dimensioned to fit against the shape of an upper part of the circumferential capsule wall that delimit the non filled upper free portion of the capsule. After the filled capsule has been placed in the support die, the direct-flow-preventing filter disc needs to get interposed between the support and welding die.
  • the disc is pre-cut at a diameter somewhat larger than the welding die.
  • the welding die gets lowered into the capsule body in order to drive the disc into a dish-shape with turned-up edges that come to lie against the upper part of the circumferential capsule wall.
  • the welding is obtained by heating the turned-up edges until the surface of a welding layer of the disc in contact with the capsule wall melts.
  • the welding process brings along a number of disadvantages.
  • First of all it requires the use of an expensive multi-layered filter disc, that needs to have said welding layer on its one side and a non-welding layer on its other side in order to prevent it from sticking to the welding die as the die is withdrawn again.
  • the welding process itself is a vulnerable process, particularly because the turned-up edges of the filter disc are prone to comprise some wrinkles that may stand in the way of having the turned-up edges properly welded against the capsule wall along the entire circumference.
  • Non-welded openings may even remain between the filter disc and the capsule wall, which may form free unhindered flowing paths for injected fluid to start flowing along at high speed during extraction.
  • the welding process may lead to the substance locally getting polluted and thus to a deterioration in flavour of extracted beverage.
  • the used materials and the welding process makes the capsule more expensive and requires special expensive equipment that needs maintenance and that may lead to stand-still during manufacturing.
  • a perforated direct-flow-preventing wall is formed by a bottom plate of a self-supporting plastic dish.
  • the perforated dish has the advantage that it can be placed inside the capsule body without welding, because the standing circumferential wall can be dimensioned such that it gets to abut against the closure disc when it is secured to the flange to close the filled capsule.
  • a disadvantage hereof however is that the perforated dish itself is an expensive and complex component, particularly since the capsule is a disposable. Furthermore, the number of openings in the perforated bottom plate of the dish is limited, which brings along limitations to the level of good distribution of the injected fluid over the charge of substance.
  • Another disadvantage of the dish stems from the possibility of solid and/or liquid extract rising back up along the circumferential wall into the space intended for injection. Soiling of this injection space brings the risk of the openings getting blocked, leading to a degradation of the distribution of the stream of fluid through the bed of substance, and therefore to a
  • the present invention aims to at least partly overcome these disadvantages or to provide a usable alternative.
  • the invention aims to provide a capsule that can be manufactured cost effective and for which a positioning and securing of a direct-flow- preventing filter disc inside a capsule body can be used for application to various capsule platforms.
  • the present invention aims to provide an improved method of securing the filter disc in the capsule body, and also provide a capsule produced by the method of the present invention.
  • the capsule for containing a substance from which a beverage can be produced according to claim 1.
  • the capsule comprises a capsule body with a side wall and a direct-flow-preventing filter disc, wherein the direct-flow-preventing filter disc has a circumferential edge zone which is in contact with the side wall.
  • a retainer is provided for securing the direct-flow- preventing filter disc in place in the capsule body, wherein the direct-flow-preventing filter disc is of a larger diameter than the retainer, and wherein said circumferential edge zone of the direct-flow-preventing filter disc is trapped between said retainer and the side wall of the capsule body.
  • a capsule is provided that makes it well possible to reliably secure a flexible micro-perforated filter disc as direct-flow-preventer inside the capsule body without needing to weld the direct-flow-preventing filter disc or the retainer thereto. Having to make use of expensive multi-layered filter discs with weldable and non-weldable layers is no longer necessary. It has now become possible to truly make use of flexible simple, for example single layered filter discs, that preceding their positioning into the capsule body may even be substantially flat. Those flexible filter discs advantageously can comprise a micro-perforation of which the number of openings is almost unlimited, which further helps to improve the level of good distribution of the injected fluid over the charge of substance, and therefore to an improvement in flavour of extracted beverage. Surprisingly it has appeared that even environmentally friendly paper filter discs can now be used as jet-breakers/distributors.
  • the securing of the filter disc together with the retainer in the upper portion of the capsule body can now be entirely mechanical, which advantageously leaves the charge of substance unhindered.
  • the capsule, including the retainer and filter disc can now be made more economic with simpler equipment that hardly requires maintenance or may lead to stand still during manufacturing.
  • the retainer may comprise an outer peripheral ring, said ring trapping said circumferential edge zone of the direct-flow-preventing filter disc between itself and the side wall.
  • the outer peripheral ring being circumferentially closed can help to guarantee that the entire circumferential edge of the direct-flow-preventing filter disc gets locked up and reliably sealed against the side wall of the capsule body.
  • the retainer may comprise radially extending spokes. Those radially extending spokes not only may strengthen the retainer but also come to lie on top of upper surface portions of the direct-flow-preventing filter disc. Thus the direct-flow-preventing filter disc is protected against possible damaging during extraction, for example caused by the injected jet of fluid in the chamber above it or by the rising pressure in the charge of substance underneath it. Yet another advantage of the spokes is that they may provide support for a closure disc that gets secured to the capsule body.
  • spokes may join one another at a centre of the retainer. This may further strengthen the retainer and thus as indicated above also the direct-flow-preventing filter disc itself.
  • a central hub can be provided at the centre of the retainer, wherein the spokes extend radially outwardly from the central hub.
  • the central hub advantageously can form a central blocking wall for the injected jet of fluid during extraction. The blocking wall then prevents a fluid injection needle to accidentally also get pierced through the direct-flow- preventing filter disc when pierced into the capsule body at a start of an extraction process.
  • the hub may help to prevent that a fluid jet that gets injected via such a needle into a chamber above the direct-flow-preventing filter disc into the capsule body, may get to directly bump against the vulnerable direct-flow-preventing filter disc and for example may cut right through it.
  • the hub may help to have the injected fluid spread out equally in all radially outward directions over the direct-flow-preventing filter disc, in particular sideways over those wedge-shaped portions of the direct-flow-preventing filter disc that lie in between the spokes. Yet another advantage of the hub is that it may provide support for a closure disc that gets secured to the capsule body.
  • the hub can be provided with a hollow.
  • the hollow then can be constructed to have a suitable fluid injection needle fit therein during piercing into the capsule body. This results in an automatic positioning of the injection needle.
  • a circumferential wall delimiting the hollow then can be provided with radially outwardly opening outlet openings, preferably one for each wedge-shaped portion of the direct-flow-preventing filter disc that lies in between the spokes that extend radially outwardly from the central hub.
  • each spoke may have, at an outer end thereof, an element which protrudes in the axial direction from the spoke, wherein the elements trap the circumferential edge zone of the direct-flow-preventing filter disc between themselves and the side wall.
  • the retainer can be made more lightweight, yet strong enough for its purpose of trapping the circumferential edge zone of the direct-flow-preventing filter disc between the retainer and the side wall of the capsule body.
  • the retainer and the side wall have one or more ribs and one or more grooves, wherein the one or more ribs fit into the one or more grooves to locate the retainer in the capsule body.
  • the one or more ribs and grooves may extend in the circumferential direction.
  • the complementary rib-groove connection may then form a circumferentially symmetrically provided snap fit connection such that it makes no difference in what position the retainer and direct-flow-preventing filter disc get inserted into the capsule body.
  • the direct-flow-preventing filter disc may comprise filter paper or other microporous material or even a perforated film.
  • the large number of openings in combination with the possibly thin single layered disc construction combines a good level of distribution of the injected fluid over the entire charge of substance without resulting in a big dropping of the injection pressure of the fluid.
  • a capsule comprising a capsule body having a frustoconical side wall, there being a filter disc and a filter disc retainer in the body, the disc having a circumferentially extending edge zone which is in contact with said side wall, said edge zone of the filter disc being between said retainer and said side wall.
  • Said retainer can comprise a peripheral ring with spokes extending radially inwardly from said ring, the spokes joining one another at the centre of the retainer.
  • said retainer may comprise a hub and a plurality of spokes which extend radially outwardly from the hub, each spoke having, at the outer end thereof, an element which protrudes in the axial direction from the spoke, said elements trapping said edge zone of the filter disc between themselves and said side wall.
  • the retainer and wall can have one or more ribs and one or more grooves, a rib fitting into a groove to locate the retainer in the capsule body.
  • the groove or grooves can be in the retainer or the capsule body and the rib or ribs can be in the capsule body or the retainer.
  • the invention also relates to a method for manufacturing of the capsule according to claim 14.
  • the method comprises the steps of providing a capsule body that comprises a side wall, filling the capsule body with a charge of a substance from which a beverage can be produced, and placing and securing a direct-flow-preventing filter disc inside the capsule body.
  • the securing of the direct-flow-preventing filter disc inside the filled capsule body takes place by means of inserting the direct-flow-preventing filter disc and a retainer into the capsule body, whereby a circumferential edge zone of the direct-flow-preventing filter disc protrudes outwardly from the retainer, the circumferential edge zone of the direct-flow-preventing filter disc being trapped between the retainer and the side wall.
  • a method is provided that makes it well possible to reliably position and secure a flexible direct-flow-preventing filter disc as described above, preferably of a type being thin-walled, single layered, vulnerable and/or micro-perforated, as a direct-flow- preventer, in one single go inside the capsule body without needing to weld the direct-flow- preventing filter disc or the retainer thereto.
