Definitions

  • the present invention relates to a capsule for the preparation of a drink, in particular a hot drink such as coffee, tea or drinking chocolate according to the preamble of claim 1.
  • Plastic capsules have the problem that, due to the different material properties of aluminum and plastic, they can not easily be pierced with the mandrel elements of the aforementioned preparation devices suitable for aluminum capsules.
  • a capsule for coffee preparation which has a frusto-conical wall with a bottom portion.
  • the bottom section is provided with a recessed structure with locally reduced material thickness, that is with flat material weakenings, which makes it possible to penetrate the mandrel elements.
  • this capsule has the disadvantage that the material is weakened in the range of lower material thickness. This weakening is unfavorable both structurally and with respect to the effect as an oxygen barrier. Moreover, these depressions are disadvantageous because objects can get caught on the edges. In addition, see these structures optically not good and there is a risk that the mandrel elements outside of the weakened areas on the capsule push, so this does not rise.
  • a capsule for preparing a beverage which comprises a wall with a lateral wall section circulating about an axis and a bottom section which intersects this axis in the proximal region of the capsule.
  • the lateral wall portion and the bottom portion define a chamber.
  • the wall has a weakening pattern with at least one tear line and comprises at least a first section and at least one second section adjoining the first section, the tear-open line running at least in sections between this first section and the second section.
  • This reinforcing structure is in this case designed such that a movement of the wall in the region of the weakening pattern against the chamber causes the first section to sink less strongly against the chamber than the second section due to the selective support by the reinforcing structure.
  • the first section is therefore more strongly supported than the second. This leads to a relative movement between the first and second sections, whereupon the wall at least in sections breaks up along the tear line for the purpose of introducing fluid.
  • the proximal side is the side of the fluid supply from the preparation device, the distal side that of the beverage discharge.
  • the axial direction, the L direction runs along the axis of symmetry of the wall, from the proximal side to the distal side.
  • the lateral or radial direction runs perpendicular to the axial direction.
  • the term “line of weakness” is meant a line weakening in an (inner and / or outer) surface of the wall, such as a slot, notch or notch, which is substantially perpendicular to the supporting one Surface is introduced, meant.
  • the weakening line can therefore be mounted on an outside and / or on an inner side of the wall facing the chamber.
  • the weakening line can be chamfered laterally to allow or improve a predefined kinking movement.
  • the weakening lines are therefore essentially linear objects which only minimally impair the function of an oxygen barrier and guide a movement pattern of the wall when pressurized, so that predetermined areas of the wall open for the purpose of introducing fluid.
  • the weakening pattern at least or sufficiently weakens the capsule such that said pressure from outside a pressure typically exerted by a preparation device is sufficient to cause the capsule to open.
  • the "tear line” is a line of weakness in the above sense, with the wall breaking up along the tear line in the above described movement.
  • the tear line is so greatly weakened that it breaks up when used as intended.
  • the weakening pattern thus allows the material to be prepared, before the movement of the wall in the above sense, i. Pressurization of the wall for the purpose of opening can not escape from the filled, closed capsule and at the same time ensures that the capsule reliably opens as intended.
  • the basic idea of the invention is that, by means of a suitable weakening pattern on the wall of the capsule (inside and / or outside, laterally and / or at the proximal bottom section), the capsule can already be pressed onto the capsule by pressure from outside or by movement of the wall region of the weakening pattern against the chamber is open. In this case, this pressure can only move the region of the weakening pattern against the chamber and does not have to act at a certain point, whereby a proper opening of the wall can be made more reliable with the preparation device.
  • the weakening pattern comprises at least one or more preferably line-shaped predetermined breaking points (tear lines) and preferably also Predetermined bending lines (weakening lines).
  • the predetermined bending lines advantageously guide the deformation or buckling of the wall in the region of the weakening pattern.
  • the pressure from the outside which thus presses the wall of the capsule against the chamber, in this case can be generated mechanically, hydrostatically or in another way.
  • the preparation device may have a projection for pressing or piercing the capsule. However, such a projection does not have to exist.
  • the term "protrusion” is to be understood as meaning truncated or sharp-pointed mandrel elements. Thus, no sharp points are necessary for the present invention, since the sections of the wall which are acted upon by said pressure can, but do not have to be, perforated in the region of the weakening pattern; they can also be touched from the outside, pushed and / or pressurized from the outside. A hydrostatic pressure build-up would be conceivable.
  • the capsule thus has the advantage that, for example, preparation devices with blunt or sharp tips or tips designed for metal capsules are able to reliably open the capsule. It is thus possible to use materials for the capsules according to the invention which, because of their nature, for example their strength, can not be pierced by projections of preparation machines oriented on aluminum capsule, since even the direct or indirect pressure of the projections on the weakening pattern is sufficient for opening and the capsule material does not have to be pierced.
  • the weakening pattern can be provided on the capsule wall such that at least a first portion of the affected capsule portion of the reinforcing structure, an additional structural element, preferably a rib or a bead against this pressure or movement is supported from the outside against the chamber, while another second portion of the capsule wall, which is separated from the first portion via at least one tear line of the weakening pattern is not or less supported, so that the pressure from the outside can move the second portion more than the first Section.
  • a direction of the notch or slots may be directed perpendicular to the respective surface portion of the wall. It is also possible to provide this direction inclined to the surface normal of the wall. In the latter case, the inner surface of the sections is then preferably smaller than its outer surface, so that the slot or Kerbides, seen from the outside inward, tapers to a center of the chamber.
  • the notch or the slot can be chamfered, that is bevelled laterally, in order to facilitate or guide the buckling or fracture movement of the section of the wall affected by the weakening pattern.
  • the chamber of the capsule is in particular a bulk material chamber for coffee powder, tea or tea powder, chocolate or milk powder or similar good.
  • Liquids such as gels or viscous liquids are also usable.
  • the capsule according to the invention improves the process of opening for fluid introduction, in particular if the opening is made by a preparation device with projections.
  • the reinforcing structure is preferably designed as a rib or bead extending at least in sections substantially in the direction of the axis L on the wall.
  • a reinforcing structure which is designed as a festmastress on the lateral wall portion rib.
  • the rib can protrude 1 to 3 millimeters over the wall and be 5 to 20 millimeters long. This design is simple and easy to manufacture by injection molding, so the rib or bead can be formed directly in one piece with the wall (either inside or outside).
  • the tear line preferably runs at least in sections between the first and the second section, so that the wall ruptures along this line due to the said relative movement.
  • the tear line runs at least partially in the proximal bottom section, in particular the tear line runs essentially radially relative to the axis in the proximal bottom section.
  • at least one radially extending slot can be used as an opening for the fluid entry per weakening line.
  • the at least one reinforcing structure more strongly supports the first portion against the external pressure effect of supporting the second portion.
  • the reinforcing structure is formed as at least partially extending in the axial direction of the capsule rib and engages supporting the first section.
  • the weakening pattern may be at least one more first weakening line which is substantially transverse to the tear line, wherein the tear line and the first line of weakness contact or intersect kinkingly.
  • the first weakening line can act as a predetermined bending line and facilitate buckling of the wall region of the weakening pattern when pressure is applied from the outside.
  • buckling effect is to be understood in this case as meaning that, when the capsule is pressurized as intended, which leads to the buckling movement of the wall along the tear line, this pressurization also leads to a bending movement along the first weakening line.
  • the first weakening line (s) may extend in sections along a closed first path, in particular a circular path around a midpoint of the proximal bottom section, and bound the bottom section radially outward with respect to the axis L.
  • the weakening pattern may advantageously comprise at least one second weakening line which is substantially parallel to the first weakening line and provides a second, inner crease line.
  • the tear line and the second weakening line also touch or intersect kinkingly.
  • the second weakening line thus leads as a predetermined bending line the bending movement of the bottom section. This can be pressed onto the plane lying within the second line of weakness against the axis L surface to open the capsule.
  • the first line of weakness and, if present, the second line of weakness around a center of the proximal bottom portion define concentric, preferably substantially circular, tracks which may be interrupted in places.
  • the bending movement is limited and guided by a pressurization from the proximal direction substantially to the bottom portion.
  • a proximal end section of the reinforcing structure is fastened or engages on an end section of the first section of the bottom section that is preferably radial with respect to the axis L.
  • the reinforcing structure is preferably shaped so that the first portion is supported at the radially outer end portion and yields less when pressurized from outside than second portions of the wall which are not supported by the reinforcing structure.
  • the first sections may extend from the first weakening line to the possibly existing second weakening line or in the absence of the second weakening line all the way to the axis L.
  • proximal bottom portion is curved convexly outwards, wherein the reinforcing structure protrudes with the proximal end portion proximally to or above this first line of weakness against the proximal bottom portion and is preferably connected there to the proximal bottom portion.
  • the particular rib-shaped reinforcing structure is secured in the chamber.
  • the outer shape of the capsule is not changed by these elements and it fits into conventional capsule cages.
  • a capsule with a plurality of tear lines and / or with a plurality of reinforcing structures, in particular extending in the L direction reinforcing ribs.
  • These ribs may be circumferentially distributed regularly spaced and each a first portion, which is associated with a tear line, respectively.
  • plurality may mean two, three, four, five, six, seven, eight, ten, or more.
  • the weakening pattern may be formed on the proximal bottom portion such that the first portions preferably form substantially radially with respect to the axis L extending and spaced apart strips or ring sections or segments.
  • the second sections may be circumferentially interposed between these first sections and preferably of strip or ring section or circular segment shape.
  • the first and second sections may form a ring or circle segmented by the tear lines.
  • the first lines of weakness may radially outwardly bound the ring or circle with respect to the axis L.
  • the second lines of weakness may limit the ring radially inward.
  • the tear lines act as substantially radially directed predetermined breaking lines; the first and second weakening lines act as predetermined bending lines which direct the bending movement of the bottom section to pressure from the outside.
  • the first portions are thinner in the circumferential direction than the second portions, preferably 3 to 12 times thinner.
  • This has the advantage that when pressure is applied with projections, the probability of hitting a first section directly is minimized.
  • the first sections are formed as strips that are substantially as wide as the ribs are thick along the circumference (eg, 1 to 2 millimeters). As a result, the strip is attached over its entire width on the proximal end of the rib and supported against the pressure from the outside.
  • the wall together with the reinforcing structure is produced in one piece and / or of a substantially frusto-conical shape.
  • the outer shape of the cup-shaped capsule is dictated by the shape of the capsule cage of the preparation device used.
  • the bottom section can be straight, curved inwards or outwards. If the capsule itself is not sufficiently oxygen-tight, the capsule can be packed in an oxygen-tight envelope or foil, for example a bag.
