Definitions

  • the present invention relates to a disposable capsule for the preparation of beverages, typically coffee, tea, or other beverages obtainable by infusion/extraction or by solution of a granular or powdery food substance.
  • disposable capsules comprising generally a cup-shaped container, defined by a wall side, a bottom wall and an opposite opening.
  • a dose of the food substance is then accommodated in said cup-shaped body, and a covering element is arranged to close the opening of the cup-shaped body, so as to retain the dose of food substance inside the capsule.
  • the bottom wall of the cup-shaped body may be perforated or perforable, with sufficiently small holes to retain the food substance inside the capsule, but large enough to allow the passage of water and/or steam necessary for the preparation of the beverage.
  • the covering element is perforated/perforable or breakable/frangible to allow the outlet of the beverage, obtained by means of water and/or steam that passes through the capsule, solubilizing and/or collecting the aroma of the food substance contained inside the capsule itself.
  • said capsules comprise a protection element, for example a film, fixed to the bottom wall of the cup-shaped body, at a peripheral edge thereof, so as to inferiorly close the perforated bottom wall, and which defines with the bottom wall itself an injection chamber for injecting water and/or pressurized steam which is injected into said chamber through needles which are inserted into said injection chamber by piercing the protection element.
  • a protection element for example a film
  • the injected pressurized fluid then enters the cup-shaped body through the holes made in the bottom wall and passes through the cup-shaped body, dissolving the food substance contained therein and, finally, the solution thus obtained escapes through the upper opening or through said fractured or perforated covering element.
  • a known problem with this solution is that often the protection element under the action of the needles that try to perforate it becomes deformed and/or bends without piercing, making it impossible to inject the fluid under pressure into the injection chamber and thus make the desired beverage.
  • One object of the present invention therefore is to obviate such a drawback of the prior art.
  • a further object is to achieve such an object in the context of a rational, effective and cost-effective solution.
  • the invention provides a capsule for the preparation of beverages, comprising a cup-shaped body provided with:
  • the invention provides a capsule for preparing beverages in which the protection element is fixed to the bottom wall and is placed in direct contact with the abutment element so as to be kept in tension by means of the abutment surface of the abutment element itself, thus obviating the possibility that the protection element may become deformed and/or bend under the action of the needles adapted to perforate it and thus solving the aforementioned drawback of the prior art capsules.
  • abutment element may extend beyond the peripheral flange, along the direction A in the direction of movement away from the upper opening.
  • the abutment element is particularly adapted to tension the protection element, in the context of a particularly simple and rational solution.
  • a further aspect of the invention provides that the abutment element may extend beyond the peripheral flange, along said direction in the direction of movement away from the upper opening, by a height of between 0.05 mm and 6 mm.
  • one aspect of the invention provides that the abutment element may extend beyond the peripheral flange by a height of up to 4 mm.
  • abutment surface of the abutment element may be coplanar to the fixing surface of the peripheral flange.
  • the protection element cannot become deformed under the action of the needles that press on it to perforate it, thanks to the abutment surface placed at the same level as the peripheral flange fixing surface, which constrains the protection element to remain extended even under said pressing action of the needles, thus making the piercing operation by the needles themselves simple and effective.
  • protection element may be fixed to the abutment surface of the abutment element.
  • the capsule according to the invention is further more effective in obviating the aforementioned drawback of the prior art capsules, or in tensioning the protection element being this fixed both peripherally by means of the flange and in a central zone by means of the abutment element.
  • Yet another aspect of the invention provides that the abutment surface of the abutment element is rounded.
  • the abutment surface is particularly adapted to contact the protection element to put it under tension, without the risk of tearing it.
  • a further aspect of the invention provides that the protection element may be fixed to the bottom wall at the fixing surface of the peripheral flange by gluing.
  • the protection element is fixed to the bottom wall in the context of a particularly simple and cost-effective solution.
  • protection element may be fixed to the bottom wall at the fixing surface of the peripheral flange by heat-sealing.
  • the protection element is fixed to the bottom wall in a particularly stable and effective manner, in the context of a particularly simple and cost-effective solution.
  • the protection element may be made of polypropylene (PP).
  • the protection element is made of a material which is particularly simple to process, therefore in the context of a solution of limited cost.
  • the protection element may be made of polylactic acid (PLA).
  • the protection element is made of a material which is particularly simple to process, therefore in the context of a solution of limited cost, as well as of a biodegradable material.
