专利说明:

[0001] This invention relates to a system for making drinks.
[0002] In particular, it concerns a system for making capsule-based drinks containing a powdered food substance (eg powdered coffee) that can be extracted by passing water through it to make a drink (coffee, for example). example). Prior art systems include a capsule holder into which the capsule is inserted. In some systems, inserted inside the capsule holder there are blades that allow the base of the capsule to be torn, making an opening, through which water can enter the capsule to interact with the food substance. The capsule also usually has a lid that allows the drink to come out of it in suitable conditions. In fact, the cap can be of various types, for example, simply perforated, or, in contrast, consisting of a sheet of metal that can be torn against protruding elements, when the pressure in the capsule increases above a predetermined threshold value.
[0003] Once the opening has been made, at the base, water can be injected into the capsule. However, the presence of powdered food substance in the capsule creates resistance to the passage of water, which can therefore partly come out of the capsule through the opening and penetrate between the capsule and the capsule holder, causing the water leak out of the drink extraction system. To avoid this, in the prior art system, there are, therefore, sealing means for creating a waterproof seal between the capsule and the capsule holder. These sealing means in particular create the watertight seal between the capsule holder and a sealing element on the surface of the capsule which is generally at an edge of the capsule. EP 1816936 B1 describes a system, for example, in which the capsule is equipped with a compressible and resilient sealing element and is compressed when it is coupled with the end of the capsule support.
[0004] In contrast, EP 1700548 B1 describes a capsule suitable for insertion into a system for making drinks with an external surface in a hollow sealing member to achieve a watertight sealing effect. The sealing member can be deformable, for example, thanks to the geometric shape.
[0005] In addition, EP 1654966 B1 describes a capsule made to be inserted into a system for the manufacture of drinks and on the outer surface of which there is an elastic sealing element made of a material, which is different from that of the capsule, similar rubber and elastic, for example silicone.
[0006] EP Patent 1816935 B1 describes a system in which the sealing member (which can be resilient) is compressed when it is coupled with the capsule holder to create a waterproof seal between the capsule and the holder of the capsule.
[0007] Finally, EP 1702543 B1 describes an alternative embodiment that, with a system in which the capsule support is equipped with at least one air passage, such that the coupling sealed with the member seal is only effective as long as the capsule holder applies minimal axial pressure to the capsule (and, in particular, the sealing member itself) and in such a way that the coupling is released as soon as the pressure exerted by the capsule holder automatically fall below a minimum pressure.
[0008] In this case, the contact surface of the capsule support, with the capsule is a substantially annular edge on which the air passages are made forming indentations.
[0009] However, this state-of-the-art technology has several disadvantages.
[0010] The indentations present on the edge of the capsule support a means that a seal can only be formed with a capsule on whose edge there is a resilient sealing element in which the indentations of the capsule support can sink.
[0011] On the other hand, the watertight seal between the capsule and the capsule holder is created by the axial pressure of the capsule holder in the capsule on the resilient sealing element. The pressure required for the seal, therefore, must be very precisely calibrated and must be sufficient to create the non-excessive seal, so that it then allows the capsule to be separated from the capsule holder.
[0012] In addition, the capsule and the resilient sealing element require significant construction precision. The level of sophistication of the technique can affect construction production costs.
[0013] In addition, the use of a sealing element made of a material that is different from that of the capsule means increased production costs.
[0014] In this context, the purpose that forms the basis of the present invention is to provide a system for the manufacture of beverages that overcomes all the above mentioned disadvantages.
[0015] In particular, the technical objective of the present invention is to provide a system for the manufacture of beverages, which allows the establishment of a watertight seal, which is an alternative to those described above.
[0016] Another objective of the present invention is to provide a system for the manufacture of drinks, which allows the establishment of a watertight seal between the capsule and the capsule support, regardless of the presence or absence of indentations or passages of the ring edge of the support of the capsule.
[0017] Another objective of the present invention is to provide a system for making beverages that creates a watertight seal between the capsule and the capsule support, which allows to reduce the dependence of the seal on the axial pressure applied by the capsule support in the capsule.
[0018] However, another objective of this technical invention is to provide a system for drinks, which allows the creation of a waterproof seal between the capsule and the capsule holder, which simplifies the construction process and does not require excessive construction accuracy, thereby reducing production costs.
[0019] The specified objectives are substantially achieved by a system for the manufacture of beverages, as described in the attached claims.
[0020] Other features and advantages of the invention are more evident in the present detailed description, with reference to the accompanying drawings that illustrate several preferred, non-limiting configurations of embodiments of a system for the manufacture of drinks, in which:
[0021] Figure 1 is an axial section of the system according to this invention;
[0022] Figure 2 is an axial section of the system of Figure 1, in a closed position;
[0023] Figure 3 shows detail III of Figure 1;
[0024] Figure 4 illustrates the alternative embodiment of the detail of Figure 3;
[0025] Figure 5 shows detail V of Figure 2;
[0026] Figure 6 illustrates an alternative embodiment of the detail of Figure 5.
[0027] It should be noted that, for clarity, in the accompanying drawings several lines are shown that refer to elements that everything that is in the background in relation to the plane of cross section (such as the annular extensions around the axis) .
[0028] With reference to the Figures, the number 1 denotes a system for making drinks according to this invention.
[0029] System 1 according to this invention includes a capsule of 2 containing at least one powdered food substance (for example coffee powder), which can be extracted by passing water under pressure through it to make a drink ( coffee, for example). In the context of the present invention, the term powdered food substance refers to any substance that can be extracted by infusion or that is soluble, for example, coffee, tea, infusions, soups, etc.
[0030] The capsule 2 includes a substantially cup-shaped body 3 having a central axis 4. Basically, the body 3 of the capsule 2 is preferably a rotating solid whose axis is the aforementioned central axis 4. The body 3 includes a bottom wall 5, a side wall 6 extending from the bottom wall 5, and, at the opposite end of the side wall 6 to the bottom wall 5 (top end), a peripheral edge 7 projecting out of the side wall 6 The body 3 of the capsule 2 can be made of various materials, such as: plastic materials, for example by injection molding or thermoforming, or metals. The capsule 2 also comprises a cap 8 associated with the peripheral edge 7 to close the upper part of the body 3. The cap can be made of aluminum foil, plastic sheet of laminated material.
[0031] The system includes a support for the capsule 9 that forms a housing 10 within it to accommodate the capsule 2. The capsule 2 can be inserted into the housing 10 through a feed opening 11 supporting the capsule 9, which is delimited in its perimeter by an annular edge 12 of the capsule support 9. In use, the capsule and the capsule support 9 can adopt a sealed configuration in which the capsule 2 is inserted in the housing 10 and the annular edge 12 of the capsule support 9 is in contact with the capsule 2 and is coupled with it, with a water-tight seal.
[0032] The watertight seal is advantageously obtained by the relative movement between the support of the capsule 9 and a contact element 13 which is also part of the system 1, in which the cap 8 of the capsule can rest at least on the peripheral edge 7 In particular, at least one of the support of the capsule 9 and the element 13 is movable with respect to the other, between an open position, in which they allow the insertion of the capsule 2 in the housing 10 through the feed opening 11, and a closed position in which, with the capsule and the capsule support 9 in the sealed configuration, between them, they close the peripheral edge 7 of the capsule 2. In the open position the capsule 2 can be positioned between the capsule support 9 and the element of contact 13 and the capsule 2 is inserted into the housing 10, effective to reach the closed position in a substantially known manner. In the closed position, the watertight seal is also created between the capsule and the contact element 13 to prevent the drink from leaking from system 1. Advantageously, this watertight seal is created at least between the cap part 8 of the capsule at the edge peripheral 7 and contact element 13.
[0033] System 1 also includes injection means 14 mounted on the capsule holder 9 to inject water under pressure into the capsule 2 through the bottom wall 5 collecting means 15 to collect the drink taken through the cap of the capsule 8.
[0034] The collection means 15 includes at least one collector 16 to transport and collect the drink taken through the cap of the capsule 8 and to take it out of the system at a drop point (not shown). Advantageously, they are associated with the contact element 13 and in particular the collecting duct 16 is, at least in part, in the contact element 13 itself. Therefore, in the closed position, the watertight seal between the capsule and the two contact elements 13 allows the collection means 15 to collect substantially all of the drink taken through the cap 8 of the cap 2. The drink can be dispensed through the cap 8 of capsule 2 in various ways (of known types). For example, if the cap 8 of the capsule is perforated and includes one or more through-holes, the drink is dispensed through the holes. If, on the contrary, as illustrated in the embodiment, the cover 8, for example, consists of a brittle metal sheet, then the contact element 13 will advantageously comprise projecting elements 36 against which the cover 8 can tear when the pressure inside the capsule 2 increases above a predetermined threshold value, following the insertion of the water injection by the injection means 14.
[0035] In contrast, the injection means 14 includes one or more injection tubes 17 which allows water to be injected into the interior of the capsule 2 through the lower wall 5 of the capsule 2. The water is injected when the capsule and the capsule support 9 are in the sealed configuration, in such a way that water does not come out of the capsule support 9.
[0036] In a first embodiment of the lower wall 5 of the capsule 2 it comprises holes for the passage of water into the capsule 2. In this way, the simple supply of pressurized water to the support of the capsule 9, through the injection tube 17 allows water to pass into the capsule 2.
[0037] In contrast, in a second embodiment, the bottom wall 5 of the capsule 2 has no holes in it and allows water to enter the capsule 2 after it has been punctured or torn. Therefore, advantageously, as in the case of the illustrated embodiment, the injection means 14 includes, in a known manner, the blades 18 or the like, preferably all of which are fixed to the support of the capsule 9 and designed to tear or perforate the bottom wall. 5 of the capsule at least to create an opening to allow water to enter the capsule 2. The blades 18 or the like can be advantageously hollow and within them can form the injection tube 17 which allows the water to be injected into the capsule 2 with the tear made by the blades 18. In the illustrated embodiment, the injection means 14 comprise blades 18 which allow the cutting (tearing) of the lower wall 5 of the capsule 2 and the water is simply supplied into the support of the capsule 9 through of an injection tube 17.
[0038] Tearing occurs at least when the capsule is completely inserted into the housing 10. Advantageously, the contact between the injection means 14 (and, in particular, the blades 18) and the lower wall 5 of the capsule 2 and the tearing action it occurs, in the known manner, due to the relative movement between the capsule 2 and injection means 14, which, as said, are advantageously fixed in the support of the capsule 9. Advantageously, the relative movement between the capsule and the support of the capsule 2 it is obtained in the known way, thanks to the presence of the contact element 13. In fact, the relative movement in the support of the capsule 9 pushes the capsule 2 in the direction of the element 13, until it comes in contact with the cap 8 of the capsule 2, at least , at the peripheral edge 7 impacting against the contact element 13 and at that point during obtaining the closed position or in the closed position, the injection means 14 and in particular the blades 18, pierce the lower wall 5 of the capsule 2.
[0039] As stated, in the sealed configuration, capsule 2 and capsule support 9 are coupled with each other with a waterproof seal. Advantageously, the sealed coupling occurs at the ring edge 12 of the capsule holder 9. In particular, at the top of the ring edge 12 of the capsule holder 9, there is a projecting ring element 19 and / or, respectively, a ring seat 20. In contrast, at the peripheral edge 7 opposite the cap 8 of the capsule 2, there is, respectively, an annular groove 21 and / or an annular tooth 22. In the sealed configuration the protruding annular element 19 is inserted into the annular groove 21 and / or respectively the ring seat 20 receives the ring tooth 22 inside. Therefore, according to this invention, it is possible that only the protruding ring element 19 and the groove 21 are present, or only the ring seat 20 and tooth 22 are present , or the protruding ring element 19, the ring seat 20, the tooth 22 and the ring groove 21 are present.
[0040] In those cases where the annular groove 21 is present, on its surface there are three parts annularly arranged in relation to the central axis 4, consisting of a lower zone 23 and two internal lateral faces 24, 25 that are laterally positioned on sides opposites of the lower zone 23. In the sealed configuration the protruding ring element 19 is sealed in contact with at least one of the inner side faces 24, 25 of the ring groove 21. That is, the protruding ring element 19 and the annular groove 21 are such that the force applied between the projecting annular element 19 and the annular groove 21, responsible for the sealing, at each point of contact, has a component transversal to the axial direction (that is, in the direction parallel to the central axis) 4) and substantially perpendicular to the inner side face or faces 24, 25, with which the protruding annular element 19 is in contact. In particular, advantageously, the inner side faces 24, 25 are at an angle to the direction defined by the central axis 4 and converge towards each other when they approach the lower zone 23.
[0041] Furthermore, advantageously, even on the surface of the protruding ring element 19 there are three parts consisting of an upper part 26 and two outer side parts 27, 28, which are positioned laterally on opposite sides in the upper part 26. In this case, the water-tight seal is ensured by lateral contact between the outer side part 27 furthest from the central axis 4 and the inner side part 24 furthest from the central axis 4, and / or by contact between the outer side part 28 closest to the axis center 4 and the inner side face 25 closest to the central axis 4.
[0042] In particular, advantageously, the outer side parts 27, 28 are at an angle to the direction defined by the central axis 4 and converge towards each other when they approach the upper part 26.
[0043] In these cases where the ring tooth 22 is present, on its surface there are three parts annularly arranged in relation to the central axis 4, composed of a tip part 29 and two outer lateral faces 30, 31 which are laterally on opposite sides the nose part 29. In the sealed configuration the annular seat 20 is sealed in contact with at least one of the outer lateral faces 30, 31 of the annular tooth 22.
[0044] Again in this case, the ring seat 20 and the ring tooth 22 are shaped in such a way that the force applied between the ring seat 20 and the ring tooth 22, responsible for the sealing, at each point of contact, has a transverse component in the axial direction and substantially perpendicular to the outer lateral face or faces 30, 31 with which the annular seat 20 is in contact.
[0045] In particular, the external side faces 30, 31 are advantageously angled with respect to the direction defined by the central axis 4 and converge towards each other when approaching the tip portion 29.
[0046] Advantageously, even on the surface of the annular seat 20, there are three parts consisting of a bottom part 32 and two internal side parts 33, 34 which are laterally on opposite sides of the bottom part 32.
[0047] In this case, the water-tight seal is ensured by lateral contact between the outer lateral face 30 furthest from the central axis 4 and the inner lateral side 33 furthest from the central axis 4, and / or by contact between the lateral face outermost 31 closest to the central axis 4 and the inner side 34 closest to the central axis 4.
[0048] In particular, the inner side parts 33, 34 are advantageously angled with respect to the direction defined by the central axis 4 and converge towards each other when approaching the bottom part 32.
[0049] Therefore, in all cases, the watertight seal is created laterally. In other words, the forces applied between the protruding annular element 19 and the annular groove 21 and / or, respectively, between the annular seat 20 and the annular tooth 22 have a component transversal to the axial direction and substantially perpendicular to the angled surfaces that are in contact. contact with each other.
[0050] As already indicated, in the closed position, capsule 2 and capsule support 9 are in the sealed configuration. In particular, in the sealed configuration, the peripheral edge 7 of the capsule 2 and the ring edge 12 of the support of the capsule 9 are coupled. During coupling, the ring edge 12 of the capsule support 9 can cause deformations in the capsule 2. In fact, the capsule 2, as already indicated, can be made, for example, of plastic or metal material that is yielding more than that of the support of the capsule 9 and can be subjected to elastic deformations of effective plastic or the insertion of the protruding ring element 19 in the ring groove 21 and / or of the ring tooth 22 in the ring seat 20. In the sealed configuration the ring groove 21 and / respectively , the tooth 22 can be elastically deformed plastically, or on at least one of the respective side faces 24, 25, 30, 31, to improve the seal.
[0051] The illustrated embodiment shows the deformation of the annular groove 21, which passes to the sealed configuration. In particular, when the capsule 2 is not coupled with the support of the capsule 9, the annular groove 21 has no deformation (Figures 3 and 4). In contrast, in the sealed configuration the ring element 19 is inserted into the ring groove 21 advantageously creating a deformation in which, consequently, with its widening (Figures 5 and 6). Advantageously, as is the case with the illustrated embodiment, the inner side face 25 of the annular groove 21, closest to the central axis 4 can be the part of the side wall 6 of the body 3 of the capsule 2. Therefore, the annular groove 21 would be substantially made on the connecting surface between the side wall 6 and the peripheral edge 7 of the capsule 2. In fact, in the illustrated embodiment, in the sealed configuration the side wall 6 of the capsule 2 near the annular groove 21 is deformed (pressed to the interior of the capsule 2) after coupling the annular groove 21 with the protruding annular element 19.
[0052] However, in general, both the ring groove 21 and the ring tooth 22 can be deformed in the sealed configuration. In particular, the deformation that would occur due to the coupling of the sealed capsule 2 with the capsule support 9 could involve the lower region 23, the tip part 29, the inner side face 24, 25 and the outer side face 30, 31.
[0053] Advantageously, in the case of an elastic deformation of the capsule 2, the capsule 2 will contribute to the generation in the support of the capsule 9 components of force that are transversal in relation to the axial direction.
[0054] The ring groove 21 and the ring tooth 22 can be made in different ways. In the preferred embodiment, the ring tooth 22 is made by folding the peripheral edge 7 of the capsule 2 on itself, that is, on the ring tooth 22 on the side of the peripheral edge 7 in the direction of the cap 8 of the capsule 2, there is an empty space 35 ( Figures 3 and 5). This void 35 can promote the deformability of the annular groove 21 and the annular tooth 22, as well as their elasticity.
[0055] Alternatively, the annular tooth 22 can simply be a protuberance protruding from the bottom of the peripheral edge 7 of the capsule 2 and, consequently, also defines, with the side wall 6, the annular groove 21 (Figures 4 and 6). In this case, the annular tooth 22 does not substantially define any empty space between it and the lid 8.
[0056] Therefore, according to this invention, it is not necessary for the waterproof seal to be created in the lower zone 23 and / or, respectively, in the tip part 29. In this way, the also water-tight seal is also guaranteed when, for example, the ring edge 2 of the capsule holder 9 has the indented surface and the capsule 2 is not provided with resilient sealing elements. Furthermore, in this way, the watertight seal is also guaranteed in cases where the upper part 26 of the annular edge 12 is destroyed, for example, by wear and, therefore, the axial sealed coupling could no longer be guaranteed.
[0057] As already indicated, in a first embodiment, on the ring edge 12 of the support of the capsule 9 only ring element 19 is identified. Advantageously, in this case, the ring element 19 can consist of an entire thickness of the ring edge 12 of the capsule support 9. In turn, the capsule 2 has on its peripheral edge 7 only the ring groove 21 and the sealed contact occurs between at least one of the inner side faces 24, 25 of the annular groove 21 and at least one of the outer side parts 27, 28 of the projecting annular element 19. In this way, the watertight seal is created regardless of the shape of the surface of the annular edge 12 the support of the capsule 9, in the upper part 26 or the presence of any irregularity in it. In fact, as already indicated, in some cases, the surface of the ring edge 12 at the top 26 may have indentations or irregularities therein. This principle also applies to the second embodiment described below. It should be noted that if the upper part 26 has indentations in it, the visible side in the accompanying drawings will correspond to a part located between two teeth positioned one after the other (in other words, the indentations would extend upwards, with reference to the upper parts 26 illustrated in the attached drawings).
[0058] In a second embodiment illustrated in the accompanying drawings, on the ring edge 12 there is the ring protruding ring element 19 and the seat 20 and on the peripheral edge there are 7 the ring groove 21 and the ring tooth 22. Again, the face inner side 25 of the annular groove 21, closer to the central axis 4 can advantageously be part of the side wall 6 of the body 3 of the capsule 2. Furthermore, advantageously, the tooth 22 is located radially further from the central axis 4 than the ring groove 21 and the ring seat 20 are positioned radially farther from the central axis 4 than the ring element 19. In the sealed configuration the ring tooth 22 is inserted in the ring seat 20 and the protruding ring element 19 is inserted in the ring groove 21 .
[0059] The ring seat 20 and the protruding ring element 19, respectively, and the ring groove 21 and the ring tooth 22 can be separated and spaced from each other. However, advantageously, the annular seat 20 and the annular groove 21, respectively, parts of an inner side part 34 and an inner face 24, respectively, with the annular element 19 and the annular tooth 22. In more detail, the side face inner 24 of the surface of the annular groove 21 which is radially furthest from the central axis 4 corresponds to the outer lateral face 31 of the surface of the annular tooth 22 closest to the central axis 4, and the outer lateral part 27 of the surface of the protruding annular element 19 which the furthest away from the central axis 4 corresponds to the inner lateral part 34 of the surface of the annular seat 20 which is closest to the central axis 4.
[0060] Looking in more detail in the operation of system 1 for the manufacture of beverages according to the present invention, the capsule 2 is inserted in the housing 10, made in the support of the capsule 9, through the feeding opening 1 delimited by the ring edge 12 of the capsule holder 9. The relative movement between the capsule holder 9 and the contact element 13 causes the cap 8 of the capsule 2 to impact against the contact element 13, at least on the peripheral edge 7 of the capsule 2 In addition, the movement of the support from the capsule 9 to the contact element 3 causes the closed position to be reached, and the insertion of the injection means 14 in the capsule 2 (that is, tearing the lower wall 5 of the capsule 2 by the blades 18). Advantageously, in the closed position, the watertight seal is created between the capsule 2 and the capsule support 9, at the ring end 12 supporting the capsule 9 and between the capsule and the contact element 13 with the contact surface between the cap 8 of the capsule 2 and of the contact element 13 (which, advantageously, occurs, at least in the part of the cap 8 which is in contact with the peripheral edge 7 of the capsule 2). Therefore, the peripheral edge 7 of the capsule 2 is advantageously fixed between the contact element 13 and the support of the capsule 9. However, as already mentioned, advantageously, the tight coupling between the capsule and the support of the capsule 9 occurs, depending on the embodiment, exclusively on one of the side faces 24, 25, 30, 31 or one of the ring side parts 27, 28, 33, 34, respectively, of the ring groove 21, the ring tooth 22, the protruding ring element 19 and seat 20.
[0061] This invention has significant advantages.
[0062] First, the watertight seal between the capsule and the capsule support is generated laterally, that is, depending on the embodiment, which occurs on the annular side parts, respectively, of the first tooth, the groove, the seat and the second tooth, allow the water-tight seal to be created even when the surface of the capsule support has indentations or is uneven and the capsule is not equipped with an elastic sealing element suitable for compressing.
[0063] Secondly, since the watertight seal between the capsule and the capsule holder is created on the sides or side faces, there is a reduction in the dependence on axial pressure sealing.
[0064] Third, the type of waterproof seal created between the capsule and the capsule holder does not require sophisticated or excessive technical checks on construction tolerances. In fact, since the sealed coupling is created between the protruding ring element and the groove, or the sealed coupling between the ring seat and the ring tooth is not created, respectively, at the bottom, the tip surface, the bottom or the upper part, but it is created on the sides and sides, and, advantageously, with the possibility of deformation, there is no need for the seat and the second tooth or the groove of the tooth and the second tooth to perfectly complement one the other axially. Finally, it should be noted that this invention is relatively easy to produce and the cost associated with implementing the invention is not very high.
[0065] The invention described above can be modified in several ways and adapted, without therefore departing from the scope of the inventive concept. 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.
