Definitions

  • the subject-matter of the present invention is a single-dose capsule for the preparation of infusion or soluble beverages in an extraction device, comprising in particular infusion holes for the optimal infusion of water to the substance to be infused.
  • the known type of capsules comprise a cup, usually made of plastic material, equipped with a circular perimeter edge adapted to obtain a sealed engagement with a relevant abutment edge of the infusion chamber so as to avoid the leakage of hot water outside of the same infusion chamber.
  • a cup usually made of plastic material

  • the water is injected into the inner cavity of the capsule through special injection nozzles of the machine that dispense an adequate amount of water at a given pressure and temperature.
  • an excessively fast flow of water through the substance does not allow the water to optimally collect the aroma from the substance, generating a beverage with a less intense flavor; conversely, an excessively slow flow of water in the substance may generate a beverage flavor that is too intense or a failure to dispense the beverage in the desired timing.
  • thermoforming it is extremely important to be able to create a capsule that allows an optimal extraction of the food substance to be obtained while maintaining a simple geometry from the manufacturing perspective, especially for capsules wherein the cup is made through a process of thermoforming, which, as is known, does not allow complex geometries to be achieved and often requires additional processing steps following thermoforming.
  • the object of the present invention is to make a capsule that overcomes the drawbacks mentioned above.
  • a single-dose capsule of the type for the preparation of a beverage for example coffee, infusion, decoction or the like, typically by means of extraction inside an extraction device, is indicated collectively at the reference number 10.

  • the front end 6 comprises a collar 7, projecting radially outwardly from the side wall 2, typically arranged at the free end of the side wall 2, with a rear face 7a facing the bottom wall 4 and suitable to create a seal when the capsule 10 is inserted in the extraction device.
  • the bottom wall 4 comprises a recessed region 41 towards the inner cavity 3.
  • the recessed region is accommodated at least partially or totally in the inner cavity 3 of the capsule.
  • the capsule 10 further comprises a pierceable or yielding bottom cover 9 which closes the recessed region 41 and a pierceable or yielding dispensing cover 8 which closes the dispensing opening 5.
  • the central axis X is perpendicular to this bottom cover 9.
  • the central axis X coincides with the axis of symmetry of the cup 1 and extends in the dispensing direction of the beverage.
  • the central axis X is the rotation axis of the solid of rotation.
  • the recessed region 41 is defined by at least one first wall 420 and a second wall 430 facing each other and spaced along a radial direction Y perpendicular to the central axis X.

  • holes means any type of opening, of any shape, for example also a gap, a cut, a notch, or in any case a perforation of any kind, suitable to allow the passage of the liquid injected into the inner cavity 11.
  • the side wall 2 has on the outside a substantially frusto-conical shape, for example formed by the succession of frusto-conical surfaces having various angular openings.
  • the bottom cover 9 is a thin film, preferably a thin film of aluminum or a plastic material, for example, a multilayer plastic material.
  • the bottom cover is a wall yielding under the action of the dispensing nozzles of the extraction device so as to create passages for the water to the recessed region 41.
  • the cup 1 At the front end 6, the cup 1 comprises a collar 7, typically arranged at the free end of side wall 2, projecting radially outwardly.
  • the collar 7 has a front face 7b facing the opening 5 of the cup 1, opposite to the rear face 7a.

  • first wall holes 421 and second wall holes 431 Due to the simultaneous presence of first wall holes 421 and second wall holes 431, an adequate distribution of the infusion liquid (water) is assured within the inner cavity 11, and thus through the food product contained.
  • a preferred variant embodiment of the cup 1 provides that, being defined as an imaginary horizontal plane P3 tangent to at least one portion of the connecting wall 410, this imaginary horizontal plane is perpendicular to the central axis X; moreover, in this connecting wall 410 there are holes formed at the bottom 411 for the passage of the liquid injected by the extraction device into the inner cavity 11.
