    description
    Technical field The present invention relates to a beverage pad for preparing a beverage, in particular by hot water extraction, according to the preamble of claim 1. The beverage may be a hot drink, in particular tea, herbal tea or soluble tea, coffee, drinking chocolate or the like. Moreover, the present invention relates to a support structure for such a beverage pad and a beverage pad system.
    PRIOR ART Drinking pads or capsules made of plastic for hot beverage preparation with preparation devices are known from the prior art. Known pads consist of a coffee mass sandwiched between a paper, cellulose or plastic filter or a multilayer plastic film which acts as an oxygen barrier. Pressed coffee beverage cups have a circular disk shape and are equatorially symmetrical so that they can be inserted in either direction in the machine specifically designed for them. So these pads have neither an upper nor a lower and are due to their rotational symmetry very easy to use in the preparation machine.
    In plastic film pads, the film is pierced in this machine by mandrel elements for fluid entry, and the water flow is generated by the film section pierced over the beverage bulk material opposite foil section pressed against tips and is thereby perforated to the beverage outlet.
    In known beverage pads, the outer shape is determined by the Kaffeemassefüllung. The coffee mass for plastic film pads is pressed with a pressure between 0.1 to 10 tons in a pill form. Due to the properties of coffee, a stable and firm shape is achieved, which is finally wrapped with the film.
    In addition to the external shape but also a strength of the prepared drink is now largely determined by the amount of beverage bulk in the pad.
    Consequently, in these pressed beverage pods with film wrap the problem that it is not readily possible, a constant shape of the pad, which is important for the optimal processing of the pad in the preparation machine, with different beverage crop, so for example. Coffee and Tea, to get. If you fill conventional beverage pads with leaves, herbal tea or other substances with a different density or a different efficiency (ie, the required volume of substance per cup) than coffee, it is not possible to produce the desired shape with these bulk solids, which for the preparation with the However, known preparation machines is necessary.
    DISCLOSURE OF THE INVENTION It is therefore an object of the present invention to provide a beverage pad which, filled with selectable beverage bulk (such as coffee or tea), allows the preparation with the same preparation machine.
    This object is achieved by a beverage pad with the features of claim 1. Accordingly, a beverage pad for the preparation of a beverage, in particular by hot water extraction, is proposed, wherein the beverage pad extends along a main plane, comprising a beverage bulk and with a preferably oxygen-tight, the beverage bulk enclosing clamping film completed, i. is wrapped. The above object is now achieved in that the beverage pad further comprises a support structure enclosed by the stretch film. This support structure provides for the main plane spaced contact surfaces for shaping support of at least parts of the tensioning film and is formed such that the voltage applied to the contact surfaces tensioning film and the support structure a cavity for receiving the beverage bulk, preferably a tea mixture, so that the beverage pad even at partial filling This cavity is dimensionally stable with beverage bulk.
    The present invention is therefore based on the finding that an oxygen-tight final beverage pad does not get its outer shape as known through a pill of pressed coffee, but that provided a support structure with at least one cavity or a chamber in the oxygen-tight sealed interior of the beverage is, wherein this support structure is formed and wrapped by the stretch film, that the support structure determines the outer shape of the beverage pad. Thus, the external shape of the beverage pad is predetermined by the self-supporting support structure and no longer dependent on the introduced bulk material. The beverage pad can, with the same outer shape and therefore guaranteed optimal processing in the preparation machine, so have a completely filled with coffee or tea or other bulk material cavity or only partially filled. It can thus be processed in particular both compactly pressed bulk material as well as loose in the pad filled bulk material with the same pad. The erfindungsbemässe beverage pad thus brings the advantage that a wide variety of drinks such as tea or coffee with the same preparation machine can be produced.
    Preferably, the support structure is formed such that the tension foil rests only on the contact surfaces and not on the beverage bulk. The support structure does not have to provide a full-surface support; it is sufficient if the support structure allows a punctual support of the tensioning foil, wherein between these support points an access to the at least one cavity for receiving the beverage bulk material can exist.
    In a preferred embodiment, the tensioning film consists of two tensioning foil parts, which are circumferentially assembled around the support structure to form a flange. The two foil sections, which may be conventional, thus preferably each cover one side of the main plane and touch outside the circumference of the support structure. Preferably, the two foil sheets are welded to a peripheral flange. In particular, then the flange can be used as in conventional pads for clamping or sealing in the preparation machine. Other enclosures of the support structure are possible.
    In one embodiment, the support structure may be formed as a hollow body. The hollow body may simply be a body of an outer wall, which has the desired shape, wherein in this outer wall preferably recesses are introduced, which allow a filling of the beverage bulk material. It can be a hollow body of revolution, that is, for example, a hollow pill shape or a deformed ellipsoid of revolution. The wall may, for example, be made by two half-shells, which are peripherally welded together. Beverage bulk material can be filled with full-surface half shells before or after through appropriate openings. Each outer surface of the half-shells provides a contact surface for the tensioning film, which is then stretched over the outer surface.
    In addition, reinforcing ribs may be provided between these half shells, which prevent the support structure from collapsing during the intended use. These reinforcing ribs can divide the interior of the hollow body into different chambers for beverage bulk material. It can also be provided openings in these reinforcing ribs, so that the chambers are fluidly connected to each other. These ribs may extend radially and / or circumferentially. The chambers may be all or only some completely or only partially filled with beverage bulk. The ribs may also be broken to allow fluid communication between the chambers.
    The wall is in this case allow piercing through mandrel elements of the preparation machine from both sides and be equatorial symmetry, so that the pad also by 180 ° bezgl. An axis in the main plane twisted into the machine can be used.
    In a preferred embodiment, the support structure comprises at least one support element, which support element extends substantially transversely or at an angle to the main plane and at a distance from the main plane provides the contact surfaces. The above-mentioned half-shells of the hollow body assume the function of the support element in the above example.
    In another example, the support member may be a spirally wound wall, wherein the spiral lies in the main plane and a height of the wall is transverse to the main plane. The stretch film is then clamped onto the end faces of the wall. A cross section may then be, for example, pills or elliptical. For this purpose, a height of the wall can decrease radially outward.
    The support structure may also comprise a plurality of support elements, that is, for example, straight walls, which are connected by at least one connecting element, which extends substantially along the main plane.
    The support member may be formed as a monolith or as a web. A longitudinal extension of the web can extend along the main plane, the contact surfaces can be spaced over its height of the monolith or of the web transversely to the main plane.
    In a preferred embodiment, the connecting element is formed as a flat, along the main plane extending bottom element with a first flat side and one of the first flat side opposite the second flat side. The or the support elements are arranged on at least one of the first and second flat sides and protrude from it. The floor element may be curved or even.
    In a refinement, one of the first and second flat sides of the bottom element forms one of the contact surfaces for supporting the tensioning foil; the other of the first and second flat sides then carries the one or more support elements, which provide more contact surfaces at the ends at free ends.
    The bottom element is preferably at least partially, preferably curved in the radially outer portion against the support elements, so that the support structure preferably forms an inner edge of the flange formed by the clamping film surrounding edge. A shell-like curved bottom element provides with the outer surface an optimal clamping system for the film, wherein the support elements may be mounted on the inner surface.
    Preferably, at least one, preferably a plurality of recesses for the fluidic connection of the first and second flat sides is provided in the bottom element. These recesses promote fluid flow of the support structure in the transverse direction, i. across the main level. At the same time, these recesses can also be used to allow a piercing of the mandrel elements in the beverage pad. This recess can therefore be placed in particular where the mandrel elements pierce through the film and thus represent desired weakenings of the wall of the floor element. In this case, a multiplicity of small through-openings or a single large through-opening can be provided through the bottom element in the region of the entry of a mandrel element and / or in other regions.
    Preferably, the support elements are arranged around a center of the bottom element, preferably along a spiral path or along a closed, preferably circular path or along a plurality of closed, preferably circular and concentrically arranged tracks. As a result, a central cavity comprising the center and radially outer adjoining annular spaces can be formed as chambers for bulk material. Here, the support elements may be webs and / or monoliths, which are arranged along the tracks.
    In a preferred embodiment, the support elements are formed as webs, which are at least partially broken along its longitudinal extent, so that between the tensioning film and the support elements a plurality of cavities for receiving beverage bulk are formed, are preferably fluidly connected to each other.
    Several cavities for beverage intake offer the advantage that depending on the beverage bulk only one cavity or more cavities can be used. If, for example, a very taste-concentrated tea used (high efficiency), so that only the middle chamber can be partially filled with it; if the tea is weaker, this chamber can also be completely filled. Even tasteless beverage bulk material can be introduced into the beverage pad filling all cavities. Due to the fluidic communication of the cavities bulk material from all chambers can be used for extraction.
    In order to further strengthen the support structure, the support element can be supported by means of at least one reinforcing rib, which is arranged between the connection element or the bottom element and the respective support element.
    Preferably, the support elements extend circumferentially about the center of the preferably substantially circular beverage pad. In this case, the reinforcing ribs then preferably extend radially. The reinforcing ribs can reach below the tensioning foil and thus provide contact surfaces themselves or leave a gap to the tensioning foil for fluid transmission. The ribs themselves may be formed as webs. Preferably, but not necessarily, they are fully connected to the connection or floor element.
    Beverage pads, which have a respect to the main plane symmetrical outer shape, which are so equatorialsymmetrisch are particularly preferred. Further, the pads may be formed so that a fluid entry through proper piercing on both sides of the beverage pad is possible. The support structure can thus be shaped so that the pad from the first and the second side pierceable and fluid discharge on the opposite side is possible. For this purpose, the support structure in the area concerned recesses or thinning, so weakenings, which allow the conventional piercing for the purpose of fluid entry and discharge.
    Preferably, the beverage pad tapers radially outward. Thus, a preparation machine can be used, which can also process conventionally pressed coffee pads, which regularly have a flattening outward pill shape. An outer shape of the support structure may therefore correspond to that of conventionally pressed coffee pills.
    Preferably, the beverage pad further comprises at least one filter element, which is arranged between the stretch film and the beverage bulk so that the beverage bulk is retained in the preparation in the beverage pad. For this purpose, therefore, the support structure can be covered at least in the region of the openings to the outside with a filter element, for example a paper or cellulose layer or a layer of woven or non-woven material. Preferably, the entire support structure is packed in a filter layer. The filter element is then not pierced by the mandrel, but pressed into the Padinnere.
    Preferably, the support structure is formed of a moldable material such as polypropylene, polyethylene, PLA and / or other injection moldable, sinterable and / or moldable materials having similar properties. A preferred material thickness is about 0.4 to 1 millimeter. This allows a cost-effective production of the pad.
    It is a further object of the present invention to provide a support structure for a beverage pad, which support structure allows the use of different beverage bulk material for the preparation of a beverage with the same preparation machine.
    This object is further achieved by a support structure according to claim 14. Accordingly, a support structure for a beverage pad is proposed as described above, wherein the support structure from the main plane spaced contact surfaces for shaping support of at least parts of a stretch film of the beverage pad provides, wherein the support structure is formed such that the tensioning foil is clamped on the contact surfaces such that a closed cavity for receiving the beverage bulk material, preferably a tea mixture, can be formed, so that the beverage pad is dimensionally stable even with partial filling of this cavity with beverage bulk.
    Moreover, the present invention relates to a beverage pad system comprising a preparation machine and a beverage pad as described above. The preparation machine has, in a manner known per se, a piercing means, in particular via piercing spikes, for the fluid entry into the pad. In such a system, it is particularly expedient for the support structure of the beverage pad to have support elements which extend essentially transversely or at an angle to the main plane, wherein these support elements are arranged such that the piercing means on the preparation machine penetrate the beverage pad outside the support elements. In this way, it is ensured that when closing the brewing chamber the piercing means do not hit a support element, which could lead to a strong increase in the closing force and damage. An essential aspect therefore also consists in the fact that the support structure is altogether tuned to the piercing means on the preparation machine such that the force required for the penetration does not exceed a maximum value, regardless of the angular position of the pad. The present invention thus relates to a capsule or a pad for the preparation of a beverage, which comprises a solid and structuring inner part. The inner part is thus responsible for the shaping of the pad, so that even with beverage bulk, which has less volume than coffee, a safe introduction into the machine in both directions is possible, so that a correct perforation of the pad and a correct extraction of or dissolution of the bulk material is possible.

    DESCRIPTION OF PREFERRED EMBODIMENTS A first preferred embodiment of the support structure 2 according to the invention will now be described with reference to FIGS. 1 to 5.
    Fig. 1 shows the first embodiment in a plan view, Fig. 4 in a perspective view. 1 and 4 it can be seen that the support structure 2 comprises a curved bottom element 3 which extends along a main plane H (see FIG. The bottom element 3 comprises a first flat side 31 and a second flat side 32. The first flat side 31 is directed against a first side of the main plane H. In Fig. 1, one looks at the second flat side 32. The second flat side 32 is directed against a second side. 3 and 5 show a view of the first flat side 31, Fig. 2 shows a cross section A-A through the support structure. 2
    The first flat side 31 is concave, that is arched against the second side; Accordingly, the second flat side 32 is convex and also curved against the second side. The bottom element 3 is a circular disc with a radially outer annular portion 33 which is curved. A bottom 37 of the bottom element 3 is located in the center of the flat circular disc 330. The bottom element 3 is bounded radially outwardly by a circular peripheral edge 34 of the ring portion 33, which due to the curvature of the Floor element 3 offset from the second side of the plane of the flat disc 330 is located. Due to the equatorial symmetrical outer shape of the support structure 2, the peripheral edge 34 lies in the main plane H (see FIG. From Fig. 2 it can be seen that the peripheral edge 34 is located at half the height of the support structure 2. An outer shape of the support structure 2 can be described with a flattened in the center area ellipse with pointed ends; the tip is formed by the peripheral edge 34. The outer shape of the support structure 2 is then described by the outer surface of a rotation body, which is formed by rotation of this cross-sectional shape about an axis through the center 37 transverse to the main plane H. The support structure 2 itself has no equatorial symmetry, only its outer shape. The support structure 2 is manufactured in one piece.
    It is also apparent from FIGS. 1, 2 and 4 that a plurality of webs 24 are arranged on the second flat side 32 of the bottom element 3 and protrude against the second side. From Fig. 4 it is further apparent that these webs 24 are tab-like elements which have circumferentially a longitudinal extent 1 and a Abragungshöhe h of the bottom element 3. The Abragungshöhe h of the center nearest webs 241 essentially defines a thickness of the support structure 2, apart from a material thickness of the bottom element 3. In addition, these webs 24 to the free end slightly tapered, ie, their longitudinal extent 1 parallel to the main plane H is shorter, the farther measured from the main plane H. As a result, the inclined surface 245 is formed. Furthermore, the webs 24 are curved and follow the respective circular path along which they are arranged around the center 36 of the bottom element 3.
    The webs 24 have at their free, directed towards the second side ends an end face, which provides a contact surface 20 for the stretch film 4. This contact surface 20 may be the front itself. The contact surface 20 can be enlarged by a thickening at the free end of the support elements 24.
    As can be seen from Fig. 1, a number of eight radially inward, so near the center lying webs 241 and eight radially outside, so center distant or close to the circumference webs 240 arranged around the center 36. The respective webs 240, 241 are arranged on concentric circular paths around the center 36. By this concentric arrangement three cavities 21 are formed: an inner space 211, a middle annulus 212 and an outer annulus 213. As can be seen in Figures 1 and 4, gaps 244 and between are interposed between the radially inner lands 241, respectively the radial outer webs 240 gaps 243 left. The inner gaps 244 extend on a circular arc on the circular path, which is about 80% to 100% of the longitudinal extension 1 of the respective webs 241. The webs 241 extend over a circular arc at an angle of about 20 ° to 30 °, in particular about 25 °. The outer gaps 243 extend on a circular arc on the circular path, which is about 10% to 15% of the longitudinal extent 1 of the respective webs 240. The webs 240 extend over a circular arc at an angle of about 30 ° to 40 °, in particular about 35 °. It can thus be seen that the outer gaps 243 are significantly smaller (factor 3 to 4) than the inner gaps 244 (see also figures which represent full-scale illustrations of preferred embodiments). This results in a strong fluid communication between the inner space 211 and the middle annulus 212, while the fluid communication between the outer annulus 213 and the middle annulus 212 is less pronounced. This is a compromise solution that allows for partial or full filling of the internal space 211 while allowing partial or full filling of the further annular spaces 212, 213, but does not require and minimizes unnecessary pressure drop into unfilled cavities.
    From the center 36 of the bottom element 3, a protruding on the second side monolithic element 23 is arranged. This pin-shaped element 23 also has a free end, which forms part of the abutment surface 20 and at the same time has the highest Abragungshöhe h with the inner webs 241 on the bottom element 3. In other words, the monolith 23 determines with webs 241 a thickness of the support structure 2.
    From Fig. 2 it is further apparent that the radially inner webs 241 have a greater height h than the radially outer webs 240. Thus, a thickness of the support structure 2 decreases to the outside.
    Fig. 1 and 4 show that the radially inner circular disc piece 330 of the bottom member 3 is provided with a large plurality of perforations 35.
    These passage openings 35 connect the first flat side 31 with the second flat side 32 of the bottom element 3. Accordingly, a fluidic connection between the two flat sides 31 and 32 is given. The passage openings 35 are in this case in four sectors of the circle, which is described by the radially inner webs 241 arranged. These passage openings 35 may have a diameter or side lengths of about 0.4 to 1 millimeter. The passage openings 35 are arranged in the region of the inner space 211 and distributed over the radius thereof. Continuous strips 350 are arranged between the sectors, which improve the stability of the bottom element 3 and thus of the support structure 2. The number of sectors is preferably four or corresponds to the number of mandrel elements of the preparation machine (typically 3) plus 1. This ensures that at least one of the mandrel elements 11 strikes a sector perforated with through-holes 35, if the bottom element 3 should be inserted on the mandrel side , Thus, piercing of the bottom element 3 is ensured.
    In addition, it can be seen in particular in FIG. 4, but also in FIG. 1, that reinforcing ribs 37 are arranged, which access the webs 24 centrally and extend from the radially outer webs 240 up to the peripheral edge 34. These reinforcing ribs 37 thus support the webs 240 against fluid pressure from the center 36, as it acts on the perpendicular to the main plane H web surfaces of the webs 240 when used as intended.
    Moreover, it can be seen from FIGS. 1 and 4 that the rib 37 between the radially inner webs 241 and the radially outer webs 240 is moved on, so that the radially inner webs 241 through the reinforcing rib 37 against pressure from Center 36 are based ago.
    The arrangement of the radially inner webs 241 and the radially outer webs 240, which are arranged at a distance from the peripheral edge 34, the three cavities 211,212, 213 are formed. These cavities 211 to 213 are in fluidic contact via the gaps 243 and 244. The central chamber 211 and the annular hollow chambers 212 to 213 are suitable for filling with beverage bulk material 8.
    As explained above, this beverage bulk material 8 can now only in the inner chamber 211, that is, in the main chamber, are introduced. If necessary, the beverage bulk material 8 can also be filled in the radially outer chamber 212 or even in the outermost chamber 213. Via the gaps 243, 244, a fluidic contact of the generally relatively centrally piercing mandrel 11 is open for fluid entry.
    In FIG. 3, the support structure 2 is shown as viewed from the first side. There again, the through holes 35 can be seen, which are arranged in the region of the flat disc 130 of the bottom element 3 in four sectors with intermediate strips 350 without perforation.
    It can be seen from FIGS. 1 to 5 that the bottom element 3 is bounded radially outward by the peripheral edge 34. The center 36 is also shown. FIG. 5 then also shows a perspective view of the first flat side 31 of the support structure 2. From FIGS. 1 to 5, it is also clear that the bottom element 3 with its first flat side 31 has half of the contact surface 20, i. on the first page, for a film element 42 (see Fig. 11). The support webs 240, 241, the monolithic element 23 and the reinforcing ribs 37 provide with their free ends on the second side of the contact surfaces 20 for supporting the stretch film 20 ready. It can also be seen from FIGS. 1 to 5 that the support elements 34 only protrude from the bottom element 3 on the second side.
    In conventional preparation machines 10 (see Fig. 11), a pad 1 in the vicinity of the center 36 for water entry along direction 12 is pierced by mandrel elements 11. So that the beverage pad 1 can be introduced independently of the machine 10, the bottom element 3, as described above, such that it is also pierceable through the mandrel elements 11 of the preparation machine 10, so that a fluid entry from both the first side and of the second side of the drinks pad 1 can be introduced. The beverage pad 1 is surrounded by a filter element 5 (see Fig. 11). This prevents the escape of beverage bulk material 8 after piercing the film. 4
    FIGS. 6 to 10 show a second preferred embodiment. In contrast to the first embodiment, the radially inner webs are provided here by webs 242 directed in a star shape against the center 36 or the monolith 23 standing there. The star-shaped webs 242 take in the embodiment according to FIGS. 6 to 10 by their arrangement in the middle of the radially outer webs 242 in addition to the support function of the tensioning film 4 by bearing surfaces 20 at free ends of the webs 242 and the function of the reinforcing ribs 37 true. The star-shaped arrangement of the continuous webs 242, a large plurality of cavities is formed, which have the form of sectors. From Fig. 6 it can be seen that the webs 240 divide the sector spaces radially. Thus, eight inner sector spaces 211 are provided, wherein a partial annular space 212 is provided radially outside of each of these sector spaces 211. Via the gap 243, the inner sector space 211 and the associated outer partial annular space 212 are fluidically connected to one another. Accordingly, in this embodiment, the possibility is given to fill different cavities with different amounts or different types of beverage bulk material 8. The webs 242 have a constant height in the area of the circular disk 330 and fall radially outward against the peripheral edge 34, so that the cross-sectional shape shown in FIG. 7, which corresponds to that of FIG. 2, is formed.
    Fig. 11 shows schematically the preparation machine 10, which receives a beverage pad 1, which comprises a support structure 2. To the support structure 2, the filter element 5 and the tensioning film 4 is attached to a first tensioning film part 41 and a second tensioning film part 42. The two clamping film parts 41, 42 are stretched over the structure 2 and radially welded together in the vicinity of the peripheral edge 34 to a flange 43.
    Moreover, it can be seen that the machine 10 can act with the thorns 11 shown schematically from the direction 12 of the fluid entry against the beverage pad 1 piercing. It can also be seen from FIG. 11 that the piercing mandrels 11 are directed against the pad enclosed in the brewing chamber in such a way that they do not strike either the central monolith 23 or a web 24. The piercing spikes only have to penetrate the perforated bottom element 3, which extends approximately in the main plane H and which does not oppose excessive resistance. When the beverage pad is penetrated on the opposite side, the piercing mandrels 11 only have to penetrate the tensioning foil 4, without encountering parts of the support structure.
    In Fig. 12, alternative arrangements of the webs 24 are shown. Fig. 12a shows that these webs can be arranged in concentric circles. Fig. 12b shows a helical arrangement of a single support element 24. Fig. 12c shows a star-shaped arrangement of the support elements 24. Fig. 12d shows a parallel arrangement of the support webs 24. Fig. 12e shows an embodiment with a plurality of monolithic elements 23 which distribute and spaced on the bottom element 3 are arranged. FIGS. 12f to 12i substantially correspond to FIGS. 12a to 12d, wherein the respective webs 24 are provided with gaps. Fig. 12j shows an arrangement of monoliths 23 along concentric circular paths.
