    The invention relates to a cup-shaped container, which has a centrally arranged, at least one perforable region comprising discontinuity region, with a lower tensile strength than the rest of the wall and bottom having container.
    Cup-shaped containers for encapsulating and sealing portioned coffee or tea are known. Open cups for subsequent filling with coffee powder already exist. Furthermore, different Becherausfiihrungen in cylindrical and conical, conical shape and designs of the cup lid as a sieve, filter or film are known. The cup base is pierced by either known, sharp or blunt needle-shaped devices, either through externally applied sharp blades or pointed blunt projections, to rupture or rupture perforations as a result of the contact pressure between the cup bottom and projection. Furthermore, there are versions of the cup bottom, in which centric surfaces of the cup bottom are designed as a thin membrane or films to be easily pierced. Point-shaped perforations, as well as slit-shaped pre-cut openings in the cup bottom are also known from the prior art.
    There are open at the top, by the user himself bcfüllbaren plastic capsules, which have a plurality of irregular webs on the capsule bottom, wherein between the webs in each case a punctiform opening is present. In this case, individual point perforations are arranged in the constantly thick capsule bottom wall, which are separated from one another by a greater distance, as well as by webs. When piercing this capsule bottom, the problem arises that the individual point perforations are at most randomly hit by one blade of the coffee maker and both random coincidence of the point perforation with the blade as well as the coincidence of the blade with the normal capsule bottom wall no defined opening is formed, but An uncontrolled tearing of the capsule floor takes place. These cracks lead to undefined openings, causing the coffee to enter the coffee or the cup catcher. Furthermore, the entire capsule bottom bends as soon as the blades of the coffee machine hit no point perforation or all blades act on the normal capsule bottom wall and can not pierce them. A backflow of Kaffeesunds after the brewing process is not prevented.
    WO 2008/028212 describes a pot-shaped, open-topped capsule with a hinged lid, a flan-like edge and a filter in the container, the capsule bottom -2- • · • * arranged, arranged. Although this filter prevents leakage of coffee and also protects against possible contamination of the capsule catcher. The disadvantage here is the need for the additional step of inserting the filter, and that the capsule bottom with the help of the blades can be difficult to pierce.
    EP 1654966 A1 describes a capsule which is made of plastic or metal, such as aluminum, and which has already been pre-filled with the respective contents (for example coffee, tea) and sealed under overpressure. The disadvantage here is that the wall thickness over the entire body of the capsule is constant and no precautions are taken to facilitate piercing the capsule bottom.
    WO 02081327 A2 describes a closed capsule, which has an easily breakable and bendable membrane, which closes an opening provided in the capsule bottom. This membrane is a continuous, foil-like and flat surface which is cut open by blades. The disadvantage here is the very tedious emptying of the capsule using a specially designed element. Furthermore, the capsule and the membrane are made of different materials, resulting in higher manufacturing costs.
    EP 1243210 A1 discloses a capsule for coffee machines in which an annular cut opening is provided on the capsule bottom which has a single web at one point of the circle. The circular surface, which is delimited by the annular cut opening, is intended to be opened over the entire surface by the action of a centrically acting blunt dome, pivoting about the web, into the capsule.
    The object of the invention is to provide a cup-shaped container of the type mentioned or a capsule, for example of stable plastic, composite material or pulp, which can be used in coffee machines, which is suitable for the use of ready-encapsulated coffee powder, and a light Opening the cup bottom, as well as an automatic maximum possible sealing of the openings ensured to reduce after the ejection of the capsule from the coffee machine the escape of coffee, even without paper filter inside, largely. On the other hand, the stable cup-shaped capsule should not be deformed uncontrollably or undesirably by the blades of the coffee machine during the piercing of the cup bottom, but can be easily opened only at precisely predefined locations and largely close again there or leave only minimal openings. without the cup-shaped container as a whole undesirable and undefined deformed.
    The solution to the problem is that a discontinuity region is limited to the outside maximum of the wall of the container and inwardly from a central region of the container bottom. The advantage of this lies in a stable middle region, which prevents the ground from collapsing when the material is pierced by the blades, as a result of which the container as a whole also has increased stability.
    According to one embodiment of the invention, the discontinuity region is interrupted radially by a plurality of webs, so that a plurality of circular segment-like weakening zones are present. Through these webs, an additional stabilization of the container bottom is achieved in order to prevent the buckling of the bottom of the container in the region of the thin discontinuity region.
    These webs may be a continuation of the remaining, thicker container wall, so that the webs have the same wall thickness as the container wall and thus are more stable against the thinner zones of weakness.
    These webs can be additionally reinforced in both the concavity of the cup-shaped container, as well as the convexity of the container bottom, so that the webs cover a small area of the discontinuity region, but have a higher cross section and cause additional stability of the container bottom.
    According to a further embodiment of the invention, these stabilizing webs can also be pulled up beyond the beaker bottom over the concave inner side of the container wall so that these webs serve as a boundary for stacking the cup-shaped containers on the inside of the container wall and the jamming or wedging of the containers stacked one inside the other prevention.
    A further advantageous feature of the invention is that the webs which subdivide the discontinuity region into weakening zones are arranged such that, depending on the number and orientation of the blades which pierce the container bottom, at most only a single web is hit by a blade while the remaining blades can always hit a free weakening zone and easily pierce it. For example, in the case of three blades, which are aligned on the common circumference offset by 120 degrees to each other, which corresponds to a -4- even tripartite division of the bolt circle, advantageously four, five, seven or eight webs evenly distributed, i. each offset by 90, 72, 51.4 or 45 degrees.
    According to a further embodiment of the invention, the discontinuity region 5 comprises at least one predetermined breaking point. In this case, the predetermined breaking points are advantageously mounted radially, directly next to the stabilizing webs. When hitting a blade on a bridge no buckling of this bridge should take place; In order to prevent this, the connection between the weakened zone and the web is additionally weakened by this predetermined breaking point, in order to allow piercing directly next to the web. According to a further embodiment of the invention, the predetermined breaking point comprises closely adjacent perforations, thereby forming an easily puncturable discontinuity region.
    According to a further embodiment of the invention, the predetermined breaking point is arranged centrally around the central region. In an advantageous manner, narrow weakening zones and stable webs alternate with each other at regular frequency (for example, 20 webs and more), so that a lamellar radially slotted perforation zone is formed, which can also be easily pierced.
    The discontinuity region or the weakening zones with the webs are advantageously circularly aligned concentrically around the center region of the cup bottom as a ring.
    In this case, the discontinuity region or the weakening zones can not be formed as a circular ring, but within a convex envelope line, for example a polygon or a geometric pattern, such as a wave pattern arranged on a circle. 25 The invention is explained in more detail with reference to the following drawings, in which: FIG.
    1 is a side view of the entire cup-shaped container,
    2 shows the cross section in the region of the cup bottom along the section I-I of Fig. 4,

    6 shows a plan view of the cup bottom with the representation of an arrangement of webs, and FIG. 7 shows various shapes and embodiments of webs in cross section along the section III-III of FIG. 6.
    Fig. 1 shows the side view of the complete cup-shaped container having a continuously extending discontinuity region 2 in the container bottom 1, which is limited to the outside of the container wall 7 and inwardly from a central region 10 10 and has a minimum wall thickness as predetermined breaking point 5.
    Fig. 2 shows the cross section along the section I-I of Fig. 4 from the container bottom 1. It is the continuously extending predetermined breaking point 5 in the discontinuity range 2 clearly visible.
    Fig. 3 shows the principle of the penetration of a blade 3 in the discontinuity region 2 of the container bottom 1, which folds flexibly into the Bchälterinnenseite and opens at the predetermined breaking point 5, wherein an adjacent web 4 is not deformed and the shape of the container bottom 1 is supported. The flexible container bottom 1 folds back after removal of the blade 3 largely back to the original position, each with the aid of educated, aligned in the container inside, flap-like tabs 6 in the container bottom 1 20 only a minimal opening remains open.
    4 shows a plan view of the container bottom 1, which is delimited by a container wall 7 and the central region 10 and has a discontinuity region 2.
    5 shows a cross section along the section II-II through the discontinuity region 2 in the container bottom 1, the discontinuity region 2 having a minimum wall thickness along the predetermined breaking point 5.
    6 shows a plan view of the container bottom 1 in a design variant with five evenly distributed webs 4, which serve as a supporting connection between the central region 10 and the container wall 7. In this embodiment, the Discontinuitätsbereich 2 is divided by the webs 4 such that five segment-like
    Deflection zones 2 'are formed, which are additionally designed along the webs 4 with predetermined breaking points 5.
