    TECHNICAL FIELD
    [0001] This invention relates to a capsule for making drinks.
    [0002] In particular, reference is made to these capsules comprising a body and a lid that closes the upper part of the body.Inside the capsule there is a powdered food substance (for example coffee powder), which can be extracted by passing water ( that can be pressurized) through it to make a drink, for example coffee. More specifically, reference is made to these capsules, in which the body comprises a bottom wall and a side wall, and which in between have a filter interposed between the bottom wall and the lid to separate the powdered food substance from at least one relevant part of the bottom wall.
    [0003] In more detail, reference is made to these capsules suitable for use in beverage preparation systems, in which the capsule is perforated in the cap to allow the injection of water (which can be pressurized) into the capsule itself, and to a central part of the bottom wall (the relevant portion), to allow the outward distribution of the drink capsule produced by the interaction of water with the powdered food substance. In such capsules the filter is positioned close to the bottom wall so that the capsule can contain a larger amount of food substance between the cover and the filter. PREVIOUS TECHNIQUE
    [0004] An example of such a capsule is given in US 2006/0236871, which describes a capsule comprising a filter made up of a rigid skeleton, having a conical central projection, in which a drill spike is inserted after drilling the lower wall. In such rigid skeletons, openings covered by a drink-permeable fabric are made, through which the drink can pass in order to then flow out of the capsule through the lower wall (through the opening made after perforation of the lower wall).
    [0005] However, rigid or semi-rigid filters have high production costs, linked to the first mold needed to manufacture them. The production of rigid or semi-rigid filters having complex structures, for example, in which openings, holes or passages, or projections are made, further increases production costs. In addition, it is added that these costs are the costs directly related to the intrinsic cost of the material used to make the filter.
    [0006] Therefore, reference is made here to these capsules in which the filter is instead substantially made of a flexible material such as paper, fabric, non-woven fabric, etc.
    [0007] For example, on the market there are capsules that have a flat tissue filter inside, fixed to the bottom wall, which is permeable to drink and at the same time can retain the food substance. Such capsules are suitable for use with drink systems, in which the element to pierce the bottom wall penetrates the inside of the capsule, remaining there for the duration of the beverage distribution, which advantageously takes place through channels made in the perforating element itself. .
    [0008] Another example is given in the patent US2012 / 0070551, which describes a capsule in which, being located at the bottom of the wall, there is a filter made of a layer of non-woven fabric for the powdered food substance from the wall. bottom of the capsule. Particularly, in one embodiment, said layer is of large dimensions and after penetration of the capsule by a piercing element, through the lower wall, said layer is raised in relation to the lower wall by the piercing element, although the filter remains intact. Therefore, the drink can pass through the filter and flow out of the capsule, for example through a conduit made in the piercing element.
    [0009] However, in some cases, the filter may be damaged, for example by cutting the perforating element, although the powder health is substantially prevented by the interference between the perforating element and the edges of the filter that involves the cut made by it.
    [0010] However, this prior art technology has several disadvantages.
    [0011] In fact, capsules, such as those described above, are not compatible with all beverage systems to prepare and, in particular, they are not compatible with some methods of perforating the lower wall capsule. In fact, in systems where the piercing element is particularly pronounced, or in systems in which the impulse applied by the piercing element on the bottom wall is particularly large, the piercing element can easily cause a tear in the filter.
    [0012] For example, in beverage systems of the type described in document EP 2000063, which use a cutting element that penetrates the first lower wall of the capsule, causing a clean cut to be linear, and immediately after it is decoupled from it, leaving a gap, the The filter positioned on the bottom wall, in accordance with the known capsules, is easily punctured or torn. In such a situation, during the subsequent dispensing, together with the beverage part of the powdered food substance it also comes out, making the dispensed drink weak and increasing the risk of clogging the tube distribution system and the malfunction of the devices connected to them. DISCLOSURE OF THE INVENTION
    [0013] In this context, the technical purpose that forms the basis of the present invention is to provide a capsule for making drinks that overcomes the above mentioned disadvantages.
    [0014] In particular, the technical objective of the present invention is to provide a capsule for making beverages, which is equipped with a low cost filter and which is suitable for use according to the various methods for drilling or cutting the lower wall.
    [0015] It is also the technical objective of the present invention to provide a beverage capsule, which allows the filtering function of the filter to be kept intact, allowing a good quality drink to be made.
    [0016] The specified technical objective and the stated objectives are substantially achieved by a capsule for making drinks as described in the attached claims. BRIEF DESCRIPTION OF THE DRAWINGS
    [0017] Other characteristics and advantages of this invention are more evident in the detailed description that follows, with reference to several preferred, non-limiting, embodiments of a capsule for making drinks, illustrated in the attached drawings, in which: Figure 1 is a vertical section a first embodiment of a capsule according to the present invention; Figure 2 is a vertical section of a first form of alternative embodiment of the capsule of Figure 1; Figure 3 is a vertical section of a second alternative embodiment of the capsule of Figure 1; Figure 4 is a vertical section of a second embodiment of a capsule according to the present invention; Figure 5 is a vertical section of a first form of alternative embodiment of the capsule of Figure 4; Figure 6 is a vertical section of a second alternative embodiment of the capsule of Figure 4. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION
    [0018] With reference to the accompanying drawings, the number 1 in its entirety indicates a capsule for making drinks according to this invention.
    [0019] Capsule 1 in accordance with the present invention contains at least one powdered food substance that can be extracted by passing water through it to make a drink. The powdered food substance, for example coffee powder, can be extracted, for example, by infusion or is soluble to make a drink such as coffee or tea, infusions, soups, etc. Capsule 1 may, if necessary, be suitable for allowing the extraction of powdered food substance, for example coffee, through the passage of pressurized water through it, for example, to make an espresso.
    [0020] The capsule 1 comprises a substantially cup-shaped body 2, comprising a bottom wall 3 and a side wall 4. In illustrated embodiments, the bottom wall 3 of the capsule 1 extends substantially in a circular shape and the side wall 4se extends from it, in such a way that in a first truncated conical approach, the upper part of it ending with an edge 5 located opposite the bottom wall 3. A cap 6 is attached to the body 2 of the capsule1 at the edge 5 and closes the upper part of the body 2 of the capsule 1. Between the cap 6 and the inner surface of the capsule of a body 2 there is a chamber 7 for containing the powdered food substance.
    [0021] Capsule 1 is therefore suitable for insertion into a beverage making system, which advantageously comprises a housing in which capsule 1 can be positioned for use to make a drink. In particular, the system, in a substantially known manner, comprises injection means for injecting water into the capsule 1 and extraction means for extracting the beverage from the capsule 1.
    [0022] For this invention, the cap 1 of the cap 6 is perforable to allow the injection of water into the chamber 7, and the lower wall 3 is perforable, to a central part 8 thereof, to allow the extraction of a drink from the capsule 1. Accordingly, the beverage-making system suitable for the use of a capsule 1 in accordance with the present invention will have injection means associated with the cap 6 of the capsule1 and the extraction means associated with the bottom wall 3 of the capsule 1 and , in particular, with a central part 8 of the bottom part 3. The bottom wall 3 of the capsule 1 according to the present invention is therefore suitable for penetration by a perforating element, which refers to any element, substantially of known type, capable to pierce, cut or tear, for example, a fixed or movable ear or blade.
    [0023] The capsule 1 also comprises a filter 9 made at least mainly in layers of a sheet of flexible material positioned inside the chamber 7 near the bottom wall 3. The filter 9 separates the powdered food substance at least from the central part 8 of the lower wall 3, and it is permeable for the drink, at the same time that it prevents the passage of powdered food substance. The filter 9 can therefore separate the powdered food substance from a limited portion of the lower wall 3, which substantially corresponds to the lower portion of the wall 3 delimited by the substantially annular portion with which the filter 9 is associated. In the embodiment illustrated in the accompanying drawings, the filter 9 separates the powdered food substance from substantially the entire surface of the lower wall 3, the filter to be advantageously associated with a substantially annular and marginal portion of the lower wall, close to the side wall 4, or on the side wall 4. However, if necessary, filter 9 can separate the powdered food substance, even from a side wall portion 4 adjacent to the bottom wall 3, if it is attached to the body 2 on the side wall 4.
    [0024] In this context, the term flexible material refers to a material that is neither rigid nor semi-rigid, for example a plastic material, although it refers to a material that can be folded, rolled over, folded over itself, and, if necessary, it is soft and can have several degrees of deformability and has a texture, such as paper, fabrics with different textures and even polymers, a non-woven fabric, a thermo-conforming fabric, a plastic film, etc. However, these examples are to be understood as being provided by way of example only, without limiting a flexible material, in accordance with this invention.
    [0025] Therefore, filter 9 can substantially be made of a layer of flexible material, such as those indicated above, in various forms, for example, mainly in the form of a disk. In any case, the present invention also covers filters made of two or more overlapping layers (all flexible as indicated above), if necessary, of different types, with different shapes or worked to assume various surface characteristics and / or shapes.
    [0026] Filter 9 is permeable to drinks thanks to the material used to make it, for example, a permeable fabric for drinking, and having a weave in such a way that it retains the substance feeding powder, and / or due to its shape, for example, a disc, which has pass-through holes, which allow the drink to pass through it and, at the same time, keep the powder.
    [0027] According to this invention, the sheet of flexible material used to make the filter 9 is shaped to form at least one projection 10 towards the cover 6 substantially in the central part 8 of the bottom wall 3. The projection 10, in particular the filter 9 is separated from the partecentral 8 of the lower wall 3. In the embodiments illustrated in the attached drawings, the projection 10 has the shape of a protuberance, located in the center of the filter 9 and in the central part 8 of the lower wall 3, which projects in relation to the profile substantially flat of the rest of the filter 9.
    [0028] Furthermore, advantageously, the projection 10 is capable of supporting itself, for example, due to its shape, and / or the folding of the starting material sheet used to make it, and / or its strength and / or thanks to a polymerization process in places, etc.
    [0029] Projection 10 can be made using several methods. However, in general, the process for making the projection may comprise an elongation step, cold or hot deformation, local polymerization (where allowed), etc. The projection 10 can also be constituted by a crease in a flat piece of material or even by folding it. However, advantageously, the process for making the projection 10 tends to reinforce it in such a way that it is capable of supporting itself.
    [0030] As already indicated, in preferred embodiments, the filter 9 covers substantially the entire surface of the lower wall3. However, the filter 9 can be in contact with the bottom wall 3 only at several points, as shown in Figures 1, 3, 4 and 6, or it can rest on the bottom wall 3, substantially adapt to it, except for the central part 8 (Figures 2 and 5). Therefore, advantageously, the filter 9 extends substantially over the entire surface of the lower wall 3 and rests on the latter, except in the central part 8, where there is the projection 10.
    [0031] However, instead of covering substantially the entire surface of the lower wall 3, as in the illustrated embodiments, the filter 9 can in several ways be limited to covering more limited portions. For example, it can only cover more than the central part 8 only of the lower wall 3, which, during the use of the capsule 1, will be penetrated by a perforation, cut or tearing element (shape not shown). In this case, advantageously, the filter 9 is substantially reduced only to the forming portion of the projection 10.
    [0032] In any case, the flexible material sheet used to make the filter 9 is directly attached to the capsule body 2 in an annular portion 11 of the capsule body 1, the annular portion 11 surrounds the partecentral 8. Advantageously, the filter 9 is fixed to the body 2 by means of takeoff or sealing.
    [0033] The annular portion 11 can be located in different areas of the body 2 of the capsule 1, for example, it can be located in the lower wall 3 around the central part 8 and, if necessary radially distanced from it, or it can be in the side wall 4, advantageously, in a region adjacent to the lower wall 3.
    [0034] Advantageously, in the preferred embodiment, the sheet of flexible material is attached to the bottom wall 3 in an annular portion 11 surrounding the central part 8. For example in the attached drawings, the sheet of flexible material is attached to the bottom wall 3 in a peripheral annular portion 11 thereof, proximal to the lateral portion 4. In an advantageous way, in the attached drawings, the flexible material sheet is connected to the lower wall 3, and more precisely to the annular portion 11, to a portion of it, which is also substantially annular and substantially corresponds to the perimeter of the flexible material sheet. However, in other forms of realization (not shown) the sheet of flexible material can be attached to the annular portion 11 in a portion thereof, which is substantially annular radially and even more than in its own perimeter and, in any case, around the portion of filter 9 corresponding to projection 10.
    [0035] As already indicated, the projection 10 can be obtained with various techniques, by molding the sheet of starting material to form a protuberance that can be in a variety of shapes. In fact, projection 10 can, for example, have a substantially conical shape (Figures 1, 2, 4 and 5), or it can be substantially dome-shaped (Figures 3 and 6).
    [0036] As indicated, the filter 9 is spaced from the bottom wall 3 in the projection 10. In the projection 10 there is a compartment 12, between the filter 9 and the central part 8, in which, in use, a perforating element can be inserted in the sequence of penetration through the partecentral 8 of the lower wall 3, without damaging the filter 9.
    [0037] Consequently, compartment 12 is formed between the portion of the flexible material sheet that forms the projection 10 and the partecentral 8 of the lower wall 3. In fact, the projection 10 forms an empty space substantially corresponding to the volume of the compartment 12 which is of a size suitable for housing a piercing element that penetrates its interior, in the central part 8 of the lower wall 3, without said piercing element being able to damage the filter 9, advantageously not making contact with the filter.
    [0038] In the first embodiment described so far, projection 10 can be supported and forms compartment 12, delimiting it (with central part 8) and giving it shape and volume.
    [0039] In a second embodiment of this invention, illustrated in Figures 4, 5 and 6, between the portion of the flexible material sheet that forms the projection 10 and the lower wall 3 of the capsule 1, there is a support element 13 that supports the filter 9 in the projection 10 after the pressures on it act towards the lower wall 3. More precisely, the support element 13 is positioned on the lower wall 3 in the central part8. The support element 13 is advantageously made of rigid or semi-rigid material and allows the portion of the flexible material sheet to be supported in the projection 10. Furthermore, in its part in contact with the projection 10, the support element 13 preferably does not comprise edges or elements that may damage the filter 9 in the projection 10, for example, after the simple pressure applied by the powdered food substance in the filter 9 or after the normal operating pressures generated inside the capsule 1 during its use.
    [0040] The support element 13 is such that it does not interfere with the entry of a piercing element. The compartment 12 is advantageously located between the support element 13 and the lower wall 3 (in particular the central part 8). In fact, in the preferred embodiment illustrated in Figures 4, 5 and 6, the support element 13, as described in more detail below, substantially completely forms compartment 12, which substantially delimits its volume between itself and the central part 8 of the lower wall 3. In other alternative embodiments (not shown) the support element 13 forms the compartment 12 together with the projection 10, that is, for example, substantially configured as a rigid skeleton, or a structure that does not substantially interfere with the volume of compartment 12, which instead disappoints mainly delimited by the projection 10.
    [0041] The support element 13 can be made with various shapes and structures. It is, at least, mainly in shapes substantially to coincide with the projection 10. Advantageously, as already indicated, the support element 13 allows the shape of the projection10 to be maintained, keeping it substantially unchanged even after depressions applied on the filter 9, acting in the direction of the lower wall 3.
    [0042] In particular, in the preferred embodiment, as shown in Figures 4, 5 and 6, the support element 13, is a hollow one-piece structure with a shape that is substantially tapered (Figures 4 and 5), or substantially in the form of a dome that has the profile of a semi-circle (Figure 6), which comprises at the base a portion of substantially annular rests 14, which can rest on the bottom wall 3, advantageously, perimeter around the central part 8. In the form of the realization , the volume of the compartment 12 is substantially equivalent to that of the cavity of the support element 13, which therefore forms the compartment 12 and delimits, together with the central part 8 of the lower wall 3.
    [0043] In an alternative (non-illustrated) embodiment, the support element 13 may instead be composed of two or more elongated, rigid or semi-rigid elements, each of which, if necessary, may have its ends connected to a ring with a circular base, to form a basket or a cage that rests on a wall of the lower capsule 3, and which is in contact with the filter 9, in the projection 10, by means of the elongated elements. In the embodiment that the support element 13 does not substantially interfere with the volume of the compartment 12, which is mainly delimited (as well as by the central part 8 of the lower wall 3) by the projection 10 (or rather, by its components positioned between elongated elongated elements) ).
    [0044] However, preferably, the support element13 is limited in its position in such a way that it cannot be displaced substantially in relation to the lower wall 3, always remaining in the central part 8 thereof. The support element 13 can be maintained in position by the filter 9 itself, and in particular by the projection 10, which, as indicated, is advantageous, and substantially shaped to correspond to the support element 13. Furthermore, in addition or alternatively, on the lower wall 3 there may be a groove (not shown) to constrain the support element 13 to a rest portion 14 thereof. Alternatively, the support element 13 can be attached to the bottom wall 3, preferably at rest 14, or it can be an integral part of the bottom wall 3.
    [0045] As shown in Figures 4, 5 and 6, the flexible material sheet, in the projection 10, is shaped in such a way that it rests substantially evenly on the support element 13. In some embodiments the support element 13 can be fixed to the flexible material sheet. Fixation can be achieved by gluing or sealing or in other substantially known ways.
    [0046] In the preferred embodiment, the support element 13 acts advantageously as a means of protection for the filter 9, in the projection 10, against the possible action of a perforating element (which can also be an element designed to cut or tear), a once the support element 13, once the piercing element has penetrated the interior of the compartment 12, it is interposed between the piercing element and the filter 9.
    [0047] Furthermore, advantageously, the support element 13 allows the communication of the fluid between the compartment 12 and the rest of the chamber 7, through the filter 9, in such a way that the drink, made during use, after the interaction of the injected water and the powdered food substance can pass through the filter 9 from the region of the chamber 7, where the powdered food substance is located in compartment 12, and then flow out of the capsule 1 in the central part 8 of the lower wall 3.
    [0048] Fluid communication can be achieved using various methods. For example, with reference to the preferred embodiment, the support element 13 comprises openings 15, visible in Figures 4, 5 and 6, through which fluid communication is possible. In the attached drawings, said openings 15 are configured as vertically extending grooves, which essentially extend towards the lower wall 3 substantially as far as the rest portion 14 of the support element 13, which is consequently interrupted therein.
    [0049] As already indicated, capsule 1 according to this invention can be used in systems for preparing capsule based drinks, in which water injection means pierce the cap 6 of the capsule1 to inject water into it, and in which the means drink extraction allow to pierce, tear or cut the bottom wall 3 of the capsule 1, in the central part 8, to allow the flow of the drink produced following the interaction between the water and the powdered food substance. In particular, a piercing element can penetrate through the lower wall 3, in the central part 8, and will be inserted in the compartment 12 (located below the projection 10), which have dimensions that are compatible with the course of the piercing element, which, therefore, cannot contact and damage the filter 9. In the second embodiment of the capsule 1 according to this invention, the holder 13 advantageously eliminates the contact between the part of the filter 9 corresponding to the projection 10 and the perforating element, on the one hand to prevent yielding of the projection 10 itself, and, on the other hand, in some embodiments, advantageously, acting as a means of protection, to be interposed between the projection 10 and the piercing element.
    [0050] The drink made in the chamber 7 can pass through the filter 9, and through the openings 15 made in the support element 13, when present, to enter the compartment 12 and, consequently, flow out through the opening created by a perforating element in the central part 8 or through a channel made in the perforating element itself that is intended to remain inserted in compartment 12 for the duration of the drunk distribution.
    [0051] This invention has important advantages.
    [0052] The capsule according to this invention allows the use of a filter composed of a sheet of inexpensive flexible material, for example, paper, although it can be used according to various methods for piercing or cutting the lower wall. In particular, thanks to the fact that the filter comprises a projection that creates a suitable compartment to receive a perforating element, the filter remains intact, even after the perforating element has penetrated into the interior of the compartment, through the lower wall. In this way, the piercing element of a beverage making system suitable for the use of the capsule according to this invention can penetrate the capsule, remaining inside it during the dispensing of the drink, or it can be dissociated from the bottom capsule wall immediately after piercing it. The. Said advantages translate into an improvement in the usability of the capsule according to this invention, since it allows users to make good quality drinks, in any case, and with any method of penetrating the bottom wall, which guarantees a substantial absence of powder in the dispensed drink.
    [0053] In addition, there is the advantage of simple production of the capsule itself, resulting from the fact that the filter used has very low production difficulties and costs, comparable to those of previous technical capsules that use a simple fabric disc as the filter.
    [0054] Finally, it should be noted that the present invention is relatively easy to manufacture and the cost associated with carrying out the invention is not very high.
    [0055] The invention described above can be modified and adapted in different ways without departing from the scope of the inventive concept.
    [0056] In addition, all the details of the invention can be replaced with other technically equivalent elements and the materials used, as well as the shapes and dimensions of the various components, may vary according to requirements.
