DETAILED DESCRIPTION

[0050] Hereinafter, the present invention is described with reference to particular embodiments, as illustrated in the accompanying drawings. However, the present invention is not limited to the particular embodiments described in the following detailed description and shown in the figures, but rather the embodiments described merely exemplify the various aspects of the present invention, the object of which is defined by the claims. Further modifications and variations of the present invention will become apparent to the man skilled in the art.

[0051] FIG. 1 schematically shows a 3D view of the system for the production of beverages, according to the prior art. The system comprises a capsule C, a container A adapted to house the capsule C during the production of the beverage and a closing element B.

[0052] The system described is a typical example of a system for producing beverages, known from the prior art, which uses a capsule made of filtering material comprising a reinforcement ring, inserted into a container designed for non-filtering capsules that must be, for example, pierced to allow the exit of the beverage from the capsule body.

[0053] Capsule C comprises a capsule body 1 made of filtering material, adapted to form the containment volume V for the product used to obtain the desired beverage, such as ground coffee.

[0054] Capsule C comprises a reinforcement ring 2 comprising a side wall 3 and a ledge 4 protruding from the side wall 3.

[0055] Capsule C further comprises a sealing element 8. The sealing element 8 is welded to the protruding ledge 4 of the reinforcement ring 2, for example heat-welded.

[0056] The container A is adapted to house the capsule C during the production of the beverage.

[0057] The container A comprises a side wall 5 and a bottom 9, forming a compartment V adapted to house the capsule C during the production. The side wall 5 of the container A comprises an inner surface 17, facing towards the compartment V. The inner surface 17 of the side wall 5 of the container A has an inclination a with respect to the bottom 9.

[0058] Hereinafter, inner surfaces are all those surfaces facing towards the compartment V, thus towards the inside of the container A, and outer surfaces are those facing in the opposite direction.

[0059] The container A further comprises an upper edge 6. The upper edge 6 comprises four recesses 7 adapted to facilitate the insertion and/or removal of the capsule C into and from the container A.

[0060] The inner surface 17 of the side wall 5 of the container A comprises a step 21 comprising a horizontal portion 15 and an upper vertical portion 14. The upper vertical portion 14 is that circular crown extending from the horizontal portion 15 to the lower end of recesses 7 of the edge 6. The container A further comprises an outlet tube 12 adapted to let the beverage exit from the container A so that it can be collected in a suitable container, such as a cup T, not shown in the figure.

[0061] The container A may finally comprise a second piercing element 20 adapted to pierce the capsule body 1 of the capsule C. The second piercing element may be contained in the outlet tube 12 or may, for example, be shaped as a hollow needle or the like.

[0062] The closing element B is adapted to enclose the capsule C during the production of the beverage in the compartment V adapted to house the capsule C during the production. The closing element B comprises a cover 11, adapted to rest on the sealing element 8, during the production of the beverage and a dispensing tube 10. The closing element B further comprises a first piercing element adapted to pierce the sealing element C and a conduit 13 through which the water dispensed under pressure for the formation of the beverage flows.

[0063] FIG. 2 schematically shows a sectional view of the system for the production of beverages shown in FIG. 1 in a use step.

[0064] In this figure, the capsule C is housed in the compartment V of the container A and the closing element B is resting on the sealing element 8 of the capsule C. The first piercing element 16 has pierced the sealing element 8 so that the water dispensed under pressure may subsequently enter into the capsule C through the conduit 13.

[0065] The figure shows that the protruding edge 4 of the reinforcement ring 2 rests on the upper edge 6 of the container A and that the lower portion of the side wall 3 of the reinforcement ring 2 is not in contact with the inner surface 17 of the container A. More specifically, the lower portion of the side wall 3 is neither in contact with the upper vertical portion 14 nor with the horizontal portion 15 of the step 21 of the inner surface 17 of the side wall 5 of the container A.

[0066] The second piercing element 20 is not in contact with the capsule body 1 of filtering material.

[0067] FIG. 3 schematically shows a sectional view of the system for the production of beverages shown in FIG. 1, in a further use step.

[0068] The figure shows how the water dispensed under pressure enters through the conduit 13 in the containment volume V of the capsule C, which contains the product for the production of the beverage and how the beverage, exiting from the filtering capsule body 1, collects into the compartment V, and then exits through the outlet tube 12.

[0069] FIG. 4 schematically shows a sectional view of the system for the production of beverages shown in FIG. 1, in a further use step.

[0070] The figure shows how the prolonged dispensing of water under pressure into the filtering capsule body 1 causes deformation thereof due to the resistance to the passage of water by the filtering material of the capsule body 1 and/or by the product for the production of the beverage contained therein.

[0071] Due to the deformation of the capsule body 1, however, the resulting beverage comes out not only from the outlet conduit 12 but also undesirably from the recesses 7 of the edge 6.

[0072] A possible solution to prevent the deformation of the capsule body 1 due to the water under pressure being dispensed would be to increase the porosity of the filtering material the capsule body 1 is made of. This would decrease the resistance of the capsule body 1 to the pressure of the water being dispensed. However, this solution is not recommended for the significant disadvantages it brings. Increasing the porosity of the capsule body 1, in fact, decreases the quality of the beverage produced, making it overly diluted or excessively speeding the infusion time. This effect is especially undesirable if the system is used, for example, to produce espresso coffee.

[0073] The capsule body 1 is not pierced by the second piercing element 20, with which it does not come into contact.

[0074] FIG. 4A schematically shows a detail of the system shown in FIG. 4.

[0075] The figure shows in detail how the resulting beverage exits from the container A through the recesses 7 of the edge 6.

[0076] The exit of the beverage from the recesses 7 is highly undesirable as it soils the exterior of the system, and because the beverage quality will be reduced as the dispensing pressure is partly released onto the recesses 7.

[0077] FIG. 5 schematically shows a sectional view of the system for the production of beverages according to an embodiment of the present invention, in a use step.

[0078] The system for the production of a beverage comprises a capsule C1 and a container A adapted to house the capsule C1 during the production; the capsule C1 comprises a capsule body 101 made of filtering material, such as filter paper or thermoformable filtering material, adapted to form a containment volume V1 for the product used to obtain the desired beverage, for example ground coffee, and a reinforcement ring 102 comprising a side wall 103 and a ledge 104 protruding from the side wall 103; the container A comprises a lateral surface 5 and a bottom 9, forming a compartment V adapted to house the capsule C1 during the production; the system is such that the side wall 103 of the reinforcement ring 102 is configured so as to form a seal with the inner surface 17 of the side wall 5 of the container, so as to prevent the leak of the beverage from the interface between the reinforcement ring 102 and the container A.

[0079] The capsule C1 may comprise a sealing element 108. The sealing element 108 may be welded to the protruding ledge 104 of the reinforcement ring 102, for example heat-welded. The sealing element 108 may be peelable, so as to be removed, if necessary, before using the capsule C1.

[0080] The container A comprises an upper edge 6. The upper edge 6 may comprise one or more recesses 7, for example adapted to facilitate the insertion and/or removal of the capsule C1 into and from the container A. The one or more recesses 7 may have, for example, a semicircular, triangular, rectangular shape or the like. Alternatively, the edge 6 may have, for example, a wavy shape or the like, so as to form projections and recesses.

[0081] The seal is formed between the side wall 103 of the reinforcement ring 102 and the inner surface 17 of the side wall 5 of the container A, underneath the one or more recesses 7. The inner surface 17 of the side wall 5 of the container A, or at least a predefined portion of the inner surface 17 of the side wall 5, may be perpendicular to the bottom 9 or may have an inclination a with respect to it. The inner surface 17 of the side wall 5 of the container A may further be continuous or may comprise, for example, a step 21 comprising a horizontal portion 15 and an upper vertical portion 14. The upper vertical portion 14 is that circular crown extending from the horizontal portion 15 to the lower end of the one or more recesses 7 of the edge 6. The horizontal portion 15 and the vertical portion 14 are in any case portions of the inner surface 17 of the side wall 5.

[0082] The container A further comprises an outlet tube 12 adapted to let the beverage exit from the container A so that it can be collected in a suitable container T, such as a cup, not shown in the figure.

[0083] The closing element B is adapted to enclose the capsule C1 during the production of the beverage in the compartment V adapted to house the capsule C1. The closing element B comprises a cover 11, adapted to rest on the sealing element 108, during the production of the beverage, or on the protruding ledge 104 of the reinforcement ring 102, if the sealing element 108 is not present, for example has been peeled prior to the insertion of the capsule C1 into the container A. The closing element B further comprises a dispensing tube 10 and a first piercing element 16 adapted to pierce the sealing element 108 of the capsule C1, if provided. The conduit 13 of the dispensing tube 10 lets the water dispensed under pressure into the capsule for the production of the beverage.

[0084] The closing element B may be configured so as to exert a force on the capsule C1 in the container A so as to ensure the contact and thus the seal between the side wall 103 of the reinforcement ring 102 and the inner surface 17 of the side wall 5 of the container. In other words, the closing element B may be configured so as to push the capsule C1 so as to ensure the contact and thus the seal between the side wall 103 of the reinforcement ring 102 and the inner surface 17 of the side wall 5 of the container. The seal between the side wall 103 of the reinforcement ring 102 and the inner surface 17 of the side wall 5 of the container, so as to avoid the leak of the beverage from the interface between the reinforcement ring 102 and the container A, may be formed in several alternative manners.

[0085] In any case, however, the seal is formed between the side wall 103 of the reinforcement ring 102 and the inner surface 17 of the side wall 5 of the container A, underneath the one or more recesses 7 of the edge 6.

[0086] More specifically, the seal may be made between the entire side wall 103 of the reinforcement ring 102 and the inner surface 17 of the side wall 5, in at least a predefined portion thereof. Alternatively, the seal may be made between the lower portion 108 of the side wall 103 of the reinforcement ring 102 and the inner surface 17 of the side wall 5, in at least a predefined portion thereof.

[0087] More specifically, the side wall 103 of the reinforcement ring 102, or only the lower portion 118 thereof, may be made so as to have an outer diameter such as to form a seal with the inner surface 17 of the side wall 5, in at least a predefined portion thereof. This can be achieved either by adapting the size of the entire capsule C1, i.e. the size of the capsule body 101 and of the reinforcement ring 102, to those of the container A, or by increasing or decreasing the thickness of the side wall 103 of the reinforcement ring 102 or only of the lower portion 118 thereof.

[0088] Alternatively, the side wall 103 of the reinforcement ring 102, or only the lower portion 118 thereof, may be made so that the outer wall thereof has an inclination with respect to the inner surface 17 of the side wall 5, in at least a predefined portion thereof, so as to form a seal with the same.

[0089] Alternatively, the profile of the outer wall of the side wall 103 of the reinforcement ring 102, or only of the lower portion 118 thereof, may be made so as to match the profile of the inner surface 17 of the side wall 5, in at least a predefined portion thereof, so as to form a seal with the same. For example, if the inner surface 17 has the step 21, the side wall 103 may be made with a corresponding step.

[0090] In the case shown in FIG. 5, for example, the seal between the side wall 103 of the reinforcement ring 102 and the inner surface 17 of the container A is made so that there is contact between the outer wall of the lower portion 118 of the side wall 103 and the upper vertical portion 14 of the step 21 of the inner surface 17. In this case, the outer surface of the side wall 103 of the reinforcement ring 102 does not have an inclination corresponding to the inclination of the upper vertical wall 14 of the step 21 of the inner surface 17 of the container A, but has such a thickness as to rest against the upper vertical portion 14 of the step 21. Even more specifically, in this case, the corner between the bottom 119 and the outer surface of the side wall 103 of the reinforcement ring 102 contacts and forms the seal with a predefined portion of the inner surface 17 of the side wall 5 of the container A.

[0091] FIG. 5 shows how the water under pressure enters through the conduit 13 in the containment volume V1 of the capsule C1, which contains the product for the production of the beverage and the beverage, exiting from the capsule body 101, collects into the compartment V to exit through the outlet tube 12.

[0092] FIG. 6 schematically shows a sectional view of the system for the production of beverages shown in FIG. 5, in a further use step.

[0093] The figure shows how the prolonged dispensing of water under pressure into the filtering capsule body 101 causes deformation thereof due to the resistance to the passage of water by the filtering material of the capsule body 101 and/or by the product for the production of the beverage contained therein.

[0094] Unlike the case shown in FIG. 4, the seal between the side wall 103 of the reinforcement ring 102 and the inner surface 17 of the container A prevents the leak of the beverage from the interface between the reinforcement ring 102 and the container A. More specifically, it prevents the leak of the beverage through the one or more recesses 7 of the edge 6.

[0095] FIG. 6A schematically shows a detail of the system shown in FIG. 6.

[0096] The figure shows in detail how the resulting beverage does not exit from the interface between the reinforcement ring 102 and the container A, more specifically through the one or more recesses 7 of the edge 6.

[0097] FIG. 7 schematically shows a sectional view of the system for the production of beverages according to a further embodiment of the present invention, in a use step.

[0098] The system for the production of a beverage comprises a capsule C2 and a container A adapted to house the capsule C2 during the production; the capsule C2 comprises a capsule body 201 made of filtering material, such as filter paper or thermoformable filtering material, adapted to form a containment volume V2 for the product used to obtain the desired beverage, for example ground coffee, and a reinforcement ring 202 comprising a side wall 203 and a ledge 204 protruding from the side wall 203; the container A comprises a lateral surface 5 and a bottom 9, forming a compartment V adapted to house the capsule C2 during the production; the system being such that the side wall 203 of the reinforcement ring 202 is configured so as to form a seal with the inner surface 17 of the side wall 5 of the container A, so as to prevent the leak of the beverage from the interface between the reinforcement ring 202 and the container A.

[0099] In the case shown in FIG. 7, the seal between the side wall 203 of the reinforcement ring 202 and the inner surface 17 of the container A is made so that there is contact between the lower surface or bottom 219 of the side wall 203 and the horizontal portion 15 of the step 21 of the inner surface 17. More specifically, the height of the side wall 203 of the reinforcement ring 202 is such that the lower surface 219 of the side wall 203 rests on the horizontal portion 15 of the step 21 of the inner surface 17 of the container A.

[0100] FIG. 8 schematically shows a sectional view of the system for the production of beverages shown in FIG. 7, in a further use step.

[0101] The figure shows how the prolonged dispensing of water under pressure into the capsule body 201 causes deformation thereof due to the resistance to the passage of water by the filtering material of the capsule body 201 and/or by the product for the production of the beverage contained therein.

[0102] Unlike the case shown in FIG. 4, the seal between the side wall 203 of the reinforcement ring 202 and the inner surface 17 of the container A prevents the leak of the beverage from the interface between the reinforcement ring 202 and the container A. More specifically, it prevents the leak of the beverage through the one or more recesses 7 of the edge 6.

[0103] FIG. 8A schematically shows a detail of the system shown in FIG. 8.

[0104] The figure shows in detail how the resulting beverage does not exit from the interface between the reinforcement ring 202 and the container A. More specifically through the one or more recesses 7 of the edge 6.

[0105] FIG. 9 schematically shows a sectional view of the system for the production of beverages according to a further embodiment of the present invention, in a use step.

[0106] The system for the production of a beverage comprises a capsule C3 and a container A adapted to house the capsule C3 during the production; the capsule C3 comprises a capsule body 301 made of filtering material, such as filter paper or thermoformable filtering material, adapted to form a containment volume V3 for the product used to obtain the desired beverage, for example ground coffee, and a reinforcement ring 302 comprising a side wall 303 and a ledge 304 protruding from the side wall 303; the container A comprises a lateral surface 5 and a bottom 9, forming a compartment V adapted to house the capsule C3 during the production; the system is such that the side wall 303 of the reinforcement ring 302 is configured so as to form a seal with the inner surface 17 of the side wall 5 of the container, so as to prevent the leak of the beverage from the interface between the reinforcement ring 302 and the container A.

[0107] In the case shown in the figure, the seal between the side wall 303 of the reinforcement ring 302 and the inner surface 17 of the container A is made so that there is contact between the outer wall of the lower portion 318 of the side wall 303 and the upper vertical portion 14 of the step 21 of the inner surface 17. In this case, the entire outer wall of the side wall 303 of the reinforcement ring 302 has an inclination corresponding to the inclination of the upper vertical portion 14 of the step 21 of the inner surface 17 of the container A. More specifically, the profile of the outer surface of the side wall 303 of the reinforcement ring 302 is shaped like a cone, corresponding to the cone-shaped profile of the upper vertical portion 14 of the step 21 of the inner surface 17 of the container A.

[0108] FIG. 9A schematically shows a detail of the system shown in FIG. 9.

[0109] The figure shows how, unlike the case shown in FIG. 4, the seal between the side wall 303 of the reinforcement ring 302 and the inner surface 17 of the container A prevents the leak of the beverage from the interface between the reinforcement ring 302 and the container A. More specifically, it prevents the leak of the beverage through the one or more recesses 7 of the edge 6.

[0110] FIG. 10 schematically shows a sectional view of the system for the production of beverages according to a further embodiment of the present invention, in a use step.

[0111] The system for the production of a beverage comprises a capsule C4 and a container A adapted to house the capsule C4 during the production; the capsule C4 comprises a capsule body 401 made of filtering material, such as filter paper or thermoformable filtering material, adapted to form a containment volume V4 for the product used to obtain the desired beverage, for example ground coffee, and a reinforcement ring 402 comprising a side wall 403 and a ledge 404 protruding from the side wall 403; the container A comprises a lateral surface 5 and a bottom 9, forming a compartment V adapted to house the capsule C4 during the production; the system is such that the side wall 403 of the reinforcement ring 402 is configured so as to form a seal with the inner surface 17 of the side wall 5 of the container, so as to prevent the leak of the beverage from the interface between the reinforcement ring 402 and the container A.

[0112] In the case shown in the figure, the seal between the side wall 403 of the reinforcement ring 402 and the inner surface 17 of the container A is made so that there is contact between the outer wall of the lower portion 418 of the side wall 403 and the upper vertical portion 14 of the step 21 of the inner surface 17. In this case, the outer surface only of the lower portion 418 of the side wall 403 of the reinforcement ring 402 has an inclination corresponding to the inclination of the upper vertical portion 14 of the step 21 of the inner surface 17 of the container A. More specifically, the profile of the outer surface of the lower portion 418 of the side wall 403 of the reinforcement ring 402 is shaped like a cone, corresponding to the cone-shaped profile of the upper vertical portion 14 of the step 21 of the inner surface 17 of the container A.

[0113] FIG. 10A schematically shows a detail of the system shown in FIG. 10.

[0114] The figure shows how, unlike the case shown in FIG. 4, the seal between the side wall 403 of the reinforcement ring 402 and the inner surface 17 of the container A prevents the leak of the beverage from the interface between the reinforcement ring 402 and the container A. More specifically, it prevents the leak of the beverage through the one or more recesses 7 of the edge 6.

[0115] Although the present invention has been described with reference to the embodiments described above, it is clear to the man skilled in the art that several modifications of the present invention may be implemented in the light of the teaching described above and within the scope of the appended claims without departing from the object and the scope of protection of the invention.

[0116] For example, although the figures show that the inner wall of the container comprises a step (see reference numeral 21), the step is not essential. The inner wall of the container may in fact be continuous and/or smooth, without steps or other structures. The inner wall may further comprise other structures, such as one or more protruding edges.

[0117] Moreover, the container adapted to house the capsule may comprise a second piercing element adapted to pierce the capsule housed therein, for the exit of the beverage. According to the present invention, however, the second piercing element should not be necessarily used since the capsule according to the present invention comprises a capsule body of filtering material which does not need to be pierced to allow the exit of the beverage.

[0118] Moreover, the capsule body of filtering material may be smooth or pleated, as shown for example for the capsule C in FIG. 1. Moreover, the capsule body may be made of permeable, filtering and thermoformable material, such as SMASH or filter paper or other filtering materials.

[0119] Moreover, the reinforcement ring may be made of any suitable materials, such as biodegradable and/or compostable and/or biobased material, such as PLA, PHA, PBS, Starch Blends, biobased PE, PET, PA, PTT.

[0120] Moreover, although the capsules, reinforcement rings and containers described all have a round shape, it is clear that the present invention is adaptable to any shape, such as square, rectangular or polygonal.

[0121] Also the dimensions of the system may be different although, preferably, the capsule is of the single-dose type.

[0122] Finally, those areas that are deemed to be known by the man skilled in the art were not described to avoid excessively uselessly shadowing the invention described.

[0123] Accordingly, the invention is not limited to the embodiments described above but is only limited by the scope of protection of the appended claims.
