Definitions

  • 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.
  • 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side and a non-welding layer on its other side in order to prevent it from sticking to the welding die as the die is withdrawn again.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.
  • 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.
  • this aim is achieved by means of the capsule for containing a substance from which a beverage can be produced according to claim 1.
  • 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 comprises 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.
  • WO-2006/11807 , WO-2017/029565 and WO-2015/193774 show examples of capsules that also have perforated filter elements that are kept in place inside a capsule body by means of some kind of ring-shaped retainer. Neither one of them however has its ring-shaped retainer lie inside an injection chamber at an inlet side of the capsule, and there perform nor has either one of them have its ring-shaped retainer being able to perform the now foreseen inventive central blocking wall function for preventing a fluid injection needle to get pierced at a center position through a direct-flow-preventing filter disc and for blocking an injected jet of fluid during beverage production.
  • the hub is hollow.
  • 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 a capsule according to claim 14.
  • 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. Having to make use of expensive multi-layered filter discs with weldable and non-weldable layers is no longer necessary. Surprisingly it has appeared that even environmentally friendly paper filter discs can now be used as jet-breakers/distributors.
  • a method of securing a filter disc in place in a filled capsule body which has a frustoconical side wall comprising inserting a filter disc and filter disc retainer into the capsule body through its wider end, the filter disc being of larger diameter than the filter disc retainer whereby a circumferential edge zone of the filter disc protrudes outwardly from the retainer, the said edge zone of the filter disc being trapped between said retainer and said side wall.
  • the capsule 10 illustrated in Figure 1 comprises a capsule body 12 with a charge of coffee C in it, a filter disc 14 and a filter disc retainer 16.
  • the body 12 includes a frustoconical side wall 18.
  • the filter disc 14 can comprise filter paper or micro perforated film.
  • the capsule body 12 and the retainer 16 are shown in Figure 2 but not the filter disc 14.
  • the body 12 comprises an internal circumferentially extending rib 20 and the retainer 16 has a circumferentially extending groove 22.
  • the rib 20 snaps into the groove 22 as the retainer 16 is inserted into the capsule body 12 thereby locating the retainer 16 with respect to the body 12.
  • FIG 3 illustrates the filter disc 14 placed over the open end of the body 12 and the retainer 16 placed on the disc 14.
  • the filter disc 14 has a larger diameter than the internal diameter of the body 12.
  • the filter disc 14 is forced into the body (see Figure 4 ).
  • the peripheral edge zone of the disc bends upwardly with respect to the centre part of the disc to form what can be considered to be a circular wall of filter paper or microporous material which is trapped between the outer face of the retainer 16 and the inner face of the wall 18 of the capsule body 12.
  • the retainer can take various forms.
  • the retainer 16 comprises an outer ring 24 in which the groove 22 is formed and radial spokes 26 which meet at the centre of the retainer.
  • the retainer 16.1 shown in Figure 5 has an outer ring 28, three radial spokes 30 and a central hub 32.
  • a retainer 16.2 is shown, this comprising a central hub 34 and radial spokes 36 extending from the hub 34. There is no outer ring. Axially extending elements 38 at the outer ends of the spokes 36 grip the wall of filter disc material between themselves and the capsule body. Each element 38 can have part of the grooves or groove 22 in it.
  • the retainer 16.3 of Figure 7 has spokes 40 radiating from the centre of the retainer and a ring 42 to which the outer ends of the spokes connect. Angled webs 44 connect the ring 42 to arcuate elements 46 which together form a discontinuous outer ring.
  • the angled position of the webs 44 allows the elements 46 to move both circumferentially and inwardly which movement reduces the overall diameter of the retainer.
  • the elements 46 are in frictional engagement with the wall of the filter disc.
  • Each element 46 can have a section of the groove 22 in it.
  • the capsule here comprises a capsule body 80 that has a frustoconical side wall 81 with a transverse closure wall 82 at its lower smaller diameter end and with an opening at its upper wider diameter end.
  • a radially outwardly protruding flange 84 encircles the wider diameter end.
  • the capsule body 80 is partly filled with a charge of substance C. With this the degree of filling is such that free space having a height H1 remains between the free upper surface of the substance C and the flange 84.
  • a direct-flow-preventing filter disc 87 is placed in a flat shape on top of the flange 84.
  • a retainer 90 of a type comparable to the one as shown in Figure 5 is placed on top of the disc 87.
  • the retainer 90 comprises an outer peripheral ring 91, a hollow central hub 92, and spokes 93 that extend in radial directions between the hub 92 and the ring 91.
  • the ring 91 has a height H2 that here is somewhat less high than the height H1 of the free space, in particular a few millimetres.
  • the ring 91 is shaped frusto-conical complementary to an upper portion of the frustoconical side wall 81 of the capsule body 80, that is to say the upper portion that circumvents the free space above the substance C. With this, the gradually upwardly increasing outer diameter of the ring 91 is smaller than or equal to the gradually upwardly increasing inner diameter of the wider end of the frustoconical side wall 81 such that it can narrowly fit therein.
  • an outer diameter D1 of the filter disc 87 is at least larger than a lower smallest outer diameter D2 of the ring 91, and here even is larger than or equal to an outer diameter D3 of the flange 84.
  • a circumferential ring-shaped edge zone 87a of the filter disc 87 that protrudes outwardly from the retainer 90 thus lies between the diameters D1 and D2, whereas a round center zone 87b of the filter disc 87 covers the entire opening.
  • the retainer 90 is pushed downwards into the free space above the substance C. With this it takes the filter disc 87 along with it into the capsule body 80. During this insertion, the circumferential edge zone 87a of the initially flat filter disc 87 angles itself around the circumferential wall of the ring 91. Owing to the decreasing inner diameter of the frustoconical side wall 81, the upwardly folded circumferential edge zone 87a then gets more and more pushed against an inner face of the side wall 81. The inward pushing goes on until the retainer 90 has lowered into the capsule body 80 over at least the height H2 of the ring 91, and maximum over the height H1 of the free space.
  • the hub 92 in this mounted position delimits the center portion 87b of the filter disc 87 in an upwards direction, whereas the spokes 93 add strength to the retainer 90 while lying spaced from the center portion 87b of the filter disc 87, such that they leave the center portion 87b of the filter disc 87 substantially free for having injected fluid to start flowing through it during extraction.
  • a closure disc 97 is secured to the flange 84 of the capsule body 80 to close it.
  • An injection chamber 98 is then delimited between the closure disc 97 on the one side and the filter disc 87 respectively the retainer 90 on the other side.
  • the closure disc 97 As soon as the closure disc 97 is secured in place, it also delimits the filter disc 87 and retainer 90 from moving upward again.
  • the narrow fit and sealing of the filter disc against the capsule side wall 82 can even simply be maintained without having to provide additional connection means, like the before mentioned rib-grooves or other suitable kinds of mechanical snap-fit connections or the like.
  • the hub 92 forms a centre support for the closure disc 97, such that a risk for premature damaging thereof is minimized.
  • a fluid injection needle (not shown), can be pierced at a center position through the closure disc 97 such that a free end of the needle automatically is delimited in the insertion direction by a bottom wall of the central hub 92 while also coming to lie in a somewhat shielded position inside a circumferential wall of the hollow central hub 92.
  • pressurized fluid can be forcedly injected through the needle into the capsule body 80. With this the jet of fluid first gets to bump against the bottom wall of the hollow central hub 92, to then get to flow radially outward via outlet openings 99 that are provided in the circumferential wall of the hub 92, and all over the central portion 87b of the filter disc 87.
  • the injected fluid then shall start to flow through (micro-)perforations in the filter disc 87 and then further towards the transverse closure wall 82 at the smaller diameter end, while thoroughly extracting substantially the entire charge of substance C.
  • an outlet opening (not shown) can be created, for example by means of the fluid pressure causing a frangible element that is provided there to break.
  • the beverage then can flow out of the capsule, for example into a cup, and is ready for consumption. This flow pattern is indicated schematically with small arrows in Figure 8d .
  • the filter disc 87 truly prevents a direct flow of the forcedly injected fluid against the substance C, whereas the retainer 90 construction prevents a direct flow of forcedly injected fluid against the filter disc 87 itself and keeps it firmly in a sealed position against the side wall 82.
  • the substance C does not get compacted by the filter disc 87 nor delimited with a tight fit by the filter disc 87.
  • the substance C can remain loosely packed inside the capsule 80 and the substance C can be given some freedom to expand during extraction.
  • Figure 9a-d which do not illustrate a capsule or a method according to the invention, a similar set of method steps are shown.
  • the retainer 90 merely comprises an outer peripheral ring 91, and thus mainly serves the purpose of helping to position the filter disc 87 at its aimed position in the capsule body 80 and there keeping its circumferential edge zone 87a trapped against the side wall 81 of the capsule body 80 in a sealing manner without additional measures like welding, gluing, or the like need to be taken.
