Definitions

  • the present invention relates to a filter paper pod for compacted coffee portions having a shape that is asymmetrical in relation to a sealing plane of a circular peripheral zone.
  • Such a filter paper pod is shown in DE 35 04 441 A1 as well as in EP 1 273 528 A1 .
  • filter paper pods to package portions of ground products of varying particle size, such as ground coffee, ground barley, tea or other similar substances, is well known in the art.
  • Standardized filter paper pods which have a certain degree of compacting and display a lenticular shape that is symmetrical in relation to the plane of the flat circular peripheral sealing zone, are likewise known. Within said flat peripheral zone the symmetrical pods display a characteristic rounded circular edge. During actual use of said standardized symmetrical pods, which have a certain degree of compacting, a drawback is manifested in that water tends initially to pass along the rounded edge rather than being forced through the central compacted part containing the product. This has the effect of reducing the quality of the brew obtained with said standardized symmetrical compacted pods.
  • said pods do not fit tightly to the filter holder of the machine that makes espresso; as a result the water tends initially to pass through the gap formed around the edge rather than through the body of the pod.
  • Asymmetrical pods having a very soft exterior are also known; as they are not compacted, they must be larger in size in order to be packed with the same product weight as standardized symmetrical compacted pods.
  • the problem to be solved is to produce compacted filter paper pods having a conformation such as to prevent water from escaping, at the start of the brewing process, into the gap formed at the edge of the pod and ensure that it is instead forced through the central part containing product,
  • the solution proposed by the present invention salves all of the problems inherent in compacted filter paper pods having a standardized symmetrical shape and makes it possible to obtain espresso coffee of excellent quality.
  • Figure 1 shows a diametral cross-section of ar asymmetrical compacted pod whose central part (C') is slightly concave and sunken in relation to the plane (P) of the flat circular peripheral sealing zone (P). It should be noted that the filter paper in the central part (C') is in contact with the underlying portion of coffee contained inside the asymmetrical pod.
  • Figure 2 shows a diametral cross-section of an espresso machine. It illustrates the initial behaviour of water during the brewing process with a standardized symmetrical compacted pod (E).
  • Figure 3 shows a diametral cross-section of an espresso machine. It illustrates the initial behaviour of water during the brewing process with an asymmetrical compacted pod (A) whose central part (C) is coplanar with the plane (P) of the circular peripheral sealing zone (Z).
  • the diameter (D) of the cavity in the section (S) forming the top part of the brewing compartment is smaller than the diameter defining the circular zone (C) inside the peripheral sealing zone (Z) of the pod (A).
  • the upper filter holder section (S) closes to form a seal not only with the lower section (I) of the pod brewing compartment, but also with part of the central zone (C) of the body of the asymmetrical pod (A).
  • This feature prevents water from escaping, even during the initial phase of brewing, into the gap (G) existing around the edge of the pod and forces the water through the central part, thereby ensuring, right from the start of the process, a homogenous, high quality brew.
  • Figure 4 is analogous to figure 3 and serves to highlight that a high quality brew may also be obtained using compacted pods (A') packed with a lower product weight.
  • the improvement in the brewing process prevents the undesired initial flow of water through the gap (G) and thus ensures greater uniformity of the brew, which is of good quality.
  • the invention naturally lends itself to different embodiments as regards both the dimensions and structural proportions, as well as the technological choices in respect of the materials to be used in the manufacturing process.
  • the innovative concept underlying the present invention essentially consists in the asymmetric shape of the compacted pod and the substantial coplanarity between the central part (C) and the plane (P) of the circular peripheral sealing zone (Z) of the pod.
