Definitions

  • the present invention relates to a capsule for beverages that is a capsule that is suitable for containing an initial product to be joined to a fluid to obtain a final product.
  • the invention relates to a single-dose and disposable capsule containing an initial product, for example like coffee powder that is able to make, by interacting with pressurized water, a final product, for example a coffee beverage.
  • the capsule is particularly configured to prepare products, for example beverages, in automatic dispensing machines.
  • the known capsules for use in dispensing machines are disposable, single-dose containers comprising an outer casing and having the shape of a glass or cup.
  • the casing usually has a base wall and a side wall defining a cavity containing the initial product, for example ground coffee or tea, from which the final product is to be obtained, for example the beverage.
  • a flanged edge extends from the side wall and is arranged around the cavity on the side opposite the base wall.
  • the cavity, at a mouth thereof is hermetically closed by a covering element, fixed to the flanged edge, so as to seal the initial product inside the container.
  • the capsule can be used in a dispensing machine in which the capsule can be inserted by a user, into a chamber of the dispensing machine.
  • the base wall of the capsule is perforated by an injection device to inject pressurized liquid, for example water, into the capsule and the covering element is perforated by a dispensing device of the dispensing machine to enable the final product to be dispensed.
  • the dispensing device of the dispensing machine comprises a dispensing plate provided with a plurality of pointed elements that, when a pressure of the fluid inside the capsule increases, engage with the covering element and perforate it in a plurality of different zones.
  • the final product can flow into a fruition container through the perforations made by the dispensing device of the dispensing machine.
  • the capsule further comprises a sealing element arranged at the flanged edge which is configured to make a fluidic seal with the dispensing machine, in particular with a protrusion-shaped housing element of the dispensing machine, the capsule being insertable into the protrusion-shaped housing element.
  • the sealing element prevents an outflow of the pressurised liquid at high operating pressure of the dispensing machine and, in use, is crushed between the housing element of the dispensing machine and the dispensing plate of the dispensing device.
  • FIG. 1 An example of a capsule with sealing element is provided by patent EP1654966 , in which the casing is made of aluminium and the sealing element is an elastic ring made of silicone rubber fixed to the flanged edge.
  • the casing is made of aluminium and the sealing element is an elastic ring made of silicone rubber fixed to the flanged edge.
  • Using aluminium for the casing of the capsule is particularly advantageous because it enables the initial product to be kept a long time inside the cavity, being impermeable to oxygen and to water vapour.
  • placing the elastomeric ring in the silicone casing requires devices to apply the silicone rubber to the flanged edge and it is difficult to produce, with the consequence that, if the sealing element is applied imprecisely, undesired leaks of water can occur during dispensing of the beverage.
  • the aluminium itself is recyclable
  • a body formed by the aluminium casing and by the silicone rubber sealing element is no longer recyclable and this constitutes a problem for the increasingly felt need to make an entirely recyclable product for the purposes of waste disposal.
  • capsules have become widespread on the market in which the casing is made of aluminium and the sealing element is a ring of compostable material, for example the sealing element is made of paper or of natural fibres to ensure that the capsule has only compostable or completely recyclable material.
  • WO2019092144 discloses a capsule having a casing made of aluminium and a cellulose-based ring.
  • the flanged edge is planar and comprises an end annular bead, at which a border of the aluminium casing is folded on itself in accordance with the prior art and extends symmetrically, in a direction parallel to an axis of symmetry of the capsule, towards the base wall and on the opposite side thereto.
  • the Applicant has verified that in many dispensing operations, for example of espresso coffee, the beverage can be preceded by dispensing of only water.
  • This defectiveness is due to the occurrence of leaks of water from the front and/or rear of the dispensing machine that, being conveyed to the fruition container intended to subsequently receive the beverage, dilute in an undesired manner the beverage to be obtained.
  • Such leaks are fluidic losses that can be frontal and/or rear losses.
  • the Applicant has also verified that in the same or in other dispensing operations, the capsule may remain suspended in the machine and not fall automatically into the inner receptacle dedicated to receiving the capsules already used. The user is thus forced to open the machine to free manually the capsule trapped in order to be able to continue to use the dispensing machine in the subsequent dispensing operations.
  • the technical purpose which forms the basis of the present invention is thus to make available a capsule that overcomes the drawbacks of capsules of known type.
  • a further purpose of the present invention is to obtain a capsule with aluminium casing and sealing element made of paper material in which the percentage of defects, that is the percentage of defective dispensing operations with respect to the total of dispensing operations conducted, is less than the defects of capsules of known type to increase dispensing efficiency.
  • Another further purpose of the present invention is to obtain a capsule, that is simple to make and of moderate cost, with aluminium casing and a sealing element made of paper material that ensures good beverage extraction quality, reducing fluidic losses, simultaneously ensuring automatic uncoupling at the end of dispensing.
  • a capsule is indicated in accordance with the present invention, which is usable in a dispensing machine, which is not illustrated. More precisely, the capsule 1 is insertable into a chamber, which is not illustrated, of the dispensing machine.
  • the capsule 1 comprises a casing 2 that has an axis Z of longitudinal extent shown in Figure 3 , for example an axis of symmetry.
  • the casing 2 extends about the axis Z.
  • the casing 2 is preferably made of aluminium, for example by drawing.
  • the casing 2 is substantially of truncated-cone shape, and i.e. shaped as a glass or cup.
  • the casing 2 comprises a base wall 201 and a side wall 202, defining a cavity that is open, shown in Figures 2 and 3 , and a flanged edge 204, which extends from the side wall 202.
  • the side wall 202 is divergent from the base wall 201.
  • the cavity 203 is suitable for containing an initial product (not illustrated) to be combined with a fluid (not illustrated) to obtain a final product (not illustrated).
  • the fluid is, preferably, a hot or cold pressurized liquid delivered into the cavity 203 in a step of injecting the fluid to obtain the final product.
  • the initial product is for example a soluble, freeze-dried, dehydrated, concentrated, percolatable, lyophilised, powdered food product -for example coffee; alternatively, the initial preparation can be for example a leaf food product - for example tea.
  • the fluid is preferably water, which is hot and pressurized, which enables a beverage to be obtained, for example coffee, barley, tea or an herbal drink.
  • the flanged edge 204 comprises an annular bead 205, which makes the end of the flanged edge 204.
  • a border 2' of the casing 2 can be, preferably, folded in the bead 205 so that it is positioned inside the bead 205. Nevertheless, other configurations of the border 2' can be possible.
  • the capsule 1 comprises a covering element 3 fixed to the flanged edge 204 so as to close the cavity 203.
  • the covering element 3 is fixed to the flanged edge 204 by heat or ultrasound welding, or gluing, opposite to the base wall 201.
  • the covering element 3 is perforable by a dispensing device of the dispensing machine so that the final product can be dispensed through the covering element 3.
  • a sealing element 4 is associated with the flanged edge 204 on the side of the base wall 201 to make a fluidic seal with the dispensing machine, for example with a housing element of the dispensing machine, the housing element being shaped as a protrusion.
  • the sealing element 4 comprises an annular body 401 made by a cellulose-based material that is made as a paper or cardboard ring, or natural fibre ring or ring made of a composition which comprises a combination of these materials.
  • the ring 401 will be cited as being made of paper and/or cardboard.
  • the sealing element 4 comprises the cellulose-based ring 401, the sealing element 4 is easily made and moreover makes the capsule 1 entirely recyclable.
  • the flanged edge 204 comprises a first portion 206, which comprises the annular bead 205, a second portion 207, contiguous to the side wall 202, and a connecting portion 208, between the first portion 206 and the second portion 207.
  • the connecting portion 208 is so shaped as to connect together the first portion 206 and the second portion 207.
  • the second portion 207 is annular and lies on a first plane, the first portion 206 is displaced towards the base wall 201 and is at least at a predetermined distance D from the first plane, between the connecting portion 208 and the side wall 202 being defined a seat 209 in which, at least partially, the ring 401 is housed.
  • the seat 209 is concave and the displacement of the first portion 206, with the entire annular bead 205, towards the base wall 201 contributes to delimiting the seat further 209 towards the base wall 201.
  • the Applicant has been able to verify experimentally an improvement of the fluidic seal and thus a reduced quantity of frontal and/or rear fluidic losses, and a considerable improvement in defectiveness due to the fall of the capsule 1 at the end of dispensing.
  • fluidic losses means leaks of water from the frontal and/or rear part of the dispensing machine that are due to a defective fluidic seal between the sealing element 4 and the dispensing machine.
  • the displacement and the consequent change in level between the first portion 206 in which the annular bead 205 is located and the second portion 207, which lies in the first plane enables a deformation to be generated in the flanged edge 204, at the connecting portion 208, which makes the flanged edge 204 more easily adaptable when the flanged edge 204, together with the ring 401, is clamped between the housing element and a dispensing plate (not illustrated) of the dispensing machine.
  • the dispensing plate is provided with a plurality of pointed elements (not shown) that, when a pressure of the fluid inside the capsule increases, engage with the covering element 3 to perforate the covering element 3 in a plurality of different zones.
  • the seat 209 is able to contain internally the ring 401 and thus possible friction between the paper and ejection guides (not shown) of the dispensing machine can be avoided that may prevent the capsule 1 from being correctly uncoupled.
  • the capsule 1 in accordance with the present invention has a surprising technical effect because it is able to reduce significantly both the defectiveness linked to the fluidic losses and the defectiveness linked to the automatic uncoupling from the dispensing machine.
  • first portion 206 is contained in a half-space facing towards the base wall 201, which half-space is defined by a second plane which is located at said predetermined distance D.
  • the distance D is the distance to which the outer portion of the flanged edge 204 is displaced, which corresponds to the first portion 206, which also comprises the annular bead 205.
  • first portion 206 comprises an annular part 206', which is contiguous to the connecting portion 208 and is planar, the annular part 206' lying on the second plane.
  • the distance D is thus measurable in a direction parallel to the axis Z between the second portion 207 of the annular flanged edge 204 and the annular part 206' of the first portion 206.
  • the predetermined distance D is preferably comprised between 0.10mm and 0.90mm, still more preferably comprised between 0.20mm and 0.60mm, still more preferably equal to 0.30.
  • the predetermined distance D can also be equal to 0.50mm.
  • one end 205' of the annular bead 205 extends to the base wall 201 as far as a distance D' from the first plane that is equal to 1.60mm.
  • the ring 401 can be contained entirely, in a direction parallel to the axis Z, inside the seat 209 or can protrude therefrom and be delimited by the annular bead 205 and be contained inside the overall dimensions of the annular bead 205 within the distance D'.
  • the annular bead 205 contributes to delimiting the seat further 209 laterally and defines, together with the connecting portion 208, a respective outer wall of the seat 209, that on the opposite side faces the side wall 202 of the capsule.
  • the seat 209 is delimited laterally by the connecting portion 208 and/or by the annular bead 205 up to 1.60mm.
  • the distance D' from the first plane is preferably greater than the thickness of the ring 401 to contain the ring 401 entirely inside the seat 209.
  • the connecting portion 208 can have a stepped truncated-cone conformation, as shown in Figures 3 to 8 , or a curved conformation, for example with a change of inclination, which is not illustrated.
  • the connecting portion 208 can be shaped as a planar surface that connects the first portion 206 and the second portion 207 or as a surface in which a change of curvature is present.
  • the ring 401 is associated with the flanged edge 204 at least in a region intended to create the fluidic seal with the dispensing machine and that is in the region with which, during dispensing, the protrusion-shaped housing elements engages.
  • the ring 401 can be associated only with the second portion 207 without necessarily abutting on the connecting portion 208 and/or the annular bead 205, and/or the side wall 202.

  • the ring 401 can be retained associated to the casing 2 by interference between the outer zone 402 and the connecting portion 208 and/or the annular bead 205.
  • the ring 401 can be stably associated with the capsule 1 without the need to be further fixed to the flanged edge 204.
  • outer zone 402 of the ring 401 abuts on the connecting portion 208, said outer zone 402 can be flexed towards the base wall 201, as shown in Figure 8 . If the inner zone 403 is planar, the outer zone 402 that is flexed can extend therefrom.
  • the inner zone 403 can extend as far as it abuts on the side wall 202 of the capsule 2, in a non-illustrated manner.
  • the ring 401 is about 1mm wide and extends as far as to abut on the side wall 202, the fluidic seal with the housing element of the dispensing machine is anyway guaranteed.
  • the ring 401 can be retained associated to the capsule 1 by interference between the inner zone 403 and the side wall 202.
  • the ring 401 can be stably associated with the capsule 1 without the need to be further fixed to the flanged edge 204.
