Definitions

  • the present invention relates to a coffee capsule for coffee machines.
  • the coffee machines using pre-filled coffee capsules are becoming increasingly widespread, particularly for household or office use. Such coffee machines are of reduced dimensions, reduced cost, and especially extremely simple to be used. In fact, it is sufficient to insert the capsule into the machine, to close the special compartment, and to actuate the dispensing. In certain machines, the dispensing is further automatically stopped once the optimal infusion amount has been reached.
  • the coffee capsules are generally made of a plastic material, they are in a cylindrical or slightly frusto-conical shape, and have a porous septum on both faces of the capsule, so as to allow the hot water dispensed by the machine pump passing through the coffee in the capsule and extracting the infusion thereof.
  • the porous septum located downstream with respect to the water dispensing direction has a considerable problem, i.e., to hardly hold the coffee powder within the capsule during dispensing.
  • the coffee granules pushed by the pressure exerted by the water dispensed by the pump, tend to pass through the small holes of the porous septum.
  • this involves a small part of the coffee powder, over time the machine tends to get dirty, also causing malfunctioning, poor hygiene, and in any case the need for a frequent cleaning.
  • the object of the present invention to provide a coffee capsule, which minimizes or suppresses the drawback set forth above, and which is constructively simple and inexpensive.
  • the coffee capsule according to the invention comprises cylindrical or slightly frusto-conical side walls 2 and a base surface 3, which define an inner cavity intended to house coffee powder.
  • the side walls 2 end superiorly with an edge 4 projecting outwardly, suitable to act as a welding surface of a perforated film 5 ( Fig. 4 ), typically made of polypropylene o another suitable plastic material, composing the upper closure of the capsule 1 and it performs the functions of holding the coffee powder within the capsule cavity, while letting hot water to pass during dispensing.
  • a perforated film 5 typically made of polypropylene o another suitable plastic material
  • the inner surface of the side walls 2 of the capsule 1 has a plurality of annular ribs 6, the main function of which is to stiffen the above-mentioned side walls 2 when they are subjected to the pressure of the dispensed fluid.
  • the base surface 3 has a plurality of holes 7 for dispensing the infusion, hence composing a porous septum.
  • the base surface 3 Externally to the cavity of the capsule 1, the base surface 3 has a projecting edge 8 connected to a central disc 10 by a plurality of spokes 9, also projecting outwardly. In this manner, a stiffening also of the base surface 3 is obtained, which surface is the most subjected to the dispensing pressure.
  • the holes 7 are arranged in segments 11 which are the resultant of the spaces not covered by the projecting edge 8, the central disc 10, and the spokes 9.
  • the holes 7 are in a triangular shape, preferably in the shape of an equilateral triangle. Such a shape allows, while keeping the area available for dispensing the infusion constant, more easily holding the coffee powder granules compared to circular holes, or also compared to holes in the shape of an elongated loop.
  • each cluster 12 comprises six holes 7 arranged in a crown with a tip of each triangle facing the crown center.
  • the holes 7 may be arranged randomly or with geometrical arrangements that are different from the one described.
  • the capsule 1 is made in a single piece.
  • the capsule 1 will be able to be made of several types of plastic materials, of the type usually used in these applications.
  • the triangular shape of the holes allows overcoming the drawback related to the leakage of coffee powder during the infusion dispensing. This allows avoiding the presence of a filtering membrane, which is typically inserted on the bottom of the prior art capsules.
  • the possibility to obtain the capsule of the invention in a single piece is a sure saving in manufacturing costs.
