Definitions

  • the present invention relates to a capsule for the infusion of granular products, in particular coffee powder.
  • a capsule for infusion products generally comprises a cup body made of a plastic material.
  • the cup body houses the coffee powder. Furthermore, the cup body is closed by a cover - normally made of a plastic material - or with a film of filtering paper or with a micro-pierced filter.
  • the beverage produced by so doing flows out of the cup body through at least one hole made in the bottom wall of the cup body itself.
  • the upper edge of the side wall of the cup body comes into contact with an upper portion of the percolation chamber.
  • the cup body in turn, has a (normally annular) projection, which extends from the base wall of the cup body itself ans strikes against a lower portion of the percolation chamber.
  • spacial devices have been designed, which can be fitted on percolating machines so as to facilitate the formation of the above-mentioned coffee cream; these devices are known as "emulsifiers" .
  • these emulsifiers should they not be subject to regular maintenance, could be affected by delivering malfunctioning, with the formation of bubbles in the beverage (foam) .
  • the main object of the present invention is to provide a coffee capsule that optimizes the way in which the the product is delivered and facilitates the formation of coffee cream in the water/coffee infusion mass.
  • the present invention also relates to the a method for the production of a final coffee infusion containing an appreciable amount of coffee cream.
  • Said method comprises the following steps, all carried out inside a capsule:
  • figure 1 shows a first perspective view of a coffee capsule according to the present invention
  • figure 2 shows a second perspective view of the same coffee capsule of figure 1;
  • FIG. 3 shows a front view of the coffee capsule shown in figures 1 and 2;
  • FIG. 4 shows a plan view of the capsule shown in figures 1, 2 and 3;
  • FIG. 5 shows a view from the bottom of the capsule shown in figures 1, 2 and 3;
  • figure 6 shows an A-A section carried out on the front view of figure 3;
  • FIG. 7 shows an enlargement of a detail of the capsule shown in figure 6;
  • number 10 indicates, as a whole, a capsule for infusion products, in particular coffee, made according to the present invention.
  • the capsule 10 comprises a cup body 20, made of a plastic material, and a cover 30 to shut the upper portion of the cup body 20.
  • the cover 30 is replaced by a micro-pierced peelable film, thus keeping the ability to separate the components unchanged.
  • the cup body 20 is defined by a side wall 21.
  • the side wall 21 is substantially shaped as a hyperboloid of one sheet (also known as "hyperbolic hyperboloid”) .
  • an infusion chamber 27 to hold the coffee powder is defined by a first upper portion 21A of the side wall, the lower surface of the cover 30 and the upper surface of the horizontal filtering partition 25.
  • This chamber is where the infusion takes place, which involves a certain amount of hot water under pressure (the pressure at which the hot water is supplied normally ranges from 5 to 7 bar) , which is fed through a central pierced area 31 of the cover 30, and the coffee powder contained in the chamber 27 itself.
  • a first infusion product (PI) pre-infusion
  • PI first infusion product
  • a pocket 40 for finely blending the first infusion product (PI) with air in order to obtain a second infusion product ( P2 ) .
  • the pocket 40 is able to deliver the second infusion product (P2) to the outside in a pulsating manner.
  • the pocket 40 is defined, on the upper side, by the filtering element 25 and, on the lower side, by an elastically deformable membrane 50 provided with a central pulsating evacuation duct 51 to evacuate the second infusion product (P2) (figure 7) .
  • the central pulsating evacuation duct 51 is periodically closed by said elastically deformable membrane 50 touching a central portion 25B of the filtering partition 25.
  • a second lower portion 21B of the side wall 21 continues under the filtering element 25 and the pocket 40, so as to act as a diffuser for the second infusion product (P2) .
  • the capsule 100 according to the present invention works as follows:
  • pre-infusion step the hot water under pressure (5-7 bar), coming from the percolating machine (not shown) , is fed into the infusion chamber 27 containing a certain amount of coffee powder; this step is called “pre-infusion step";
  • the first infusion product (PI) is fed under pressure into the pocket 40; as the amount of first infusion product (PI) inside the pocket 40 increases, the elastically deformable membrane 50 elastically deforms downward (following an arrow (Fl) - figure 7); this downward movement of the elastically deformable membrane 50 causes the detachment of the mouth 51A of the central pulsating evacuation duct 51 from the central portion 25B of the horizontal filtering partition 25; this permits the micro- pulsating expulsion of almost the entire amount of first infusion product (PI) contained in the pocket 40 through the central evacuation duct 51;
  • the membrane 50 tends to return to its initial position (following an arrow ( F2 ) - figure 7), thus sucking into the pocket 40 the air that is enclosed in the space defined by the second lower portion 21B of the side wall 21; said air remains trapped in the pocket 40 when the membrane goes back to resting against the central portion 25B of the horizontal filtering element 25, so that the mouth 51A is closed again;
  • the process for making the second infusion product (P2) (intimate blending of coffee infusion and air, so as to form coffee cream) is repeated, in a pulsating manner, for a great number of times, until all the product of the two infusions is entirely drained into a cup (not shown) through the lower portion 21B of the side wall 21;
  • the horizontal filtering partition 25 is located in the narrowest spot of the side wall 21, which, as already mentioned above, is advantageously substantially shaped as a hyperboloid of one sheet (also known as "hyperbolic hyperboloid") .
  • the side wall 21 is divided into two distinct portions 21A, 21B, which are fixed together with known methods (for example, by interlocking them or by means of ultrasonic welding) .
  • the cover 30 and the horizontal filtering partition 25 are also fixed.
  • the main advantage of the coffee capsule according to the present invention lies in the possibility to make a coffee with a large content of coffee cream, increasing at the same time the fullness of the coffee itself thanks to the first pre-infusion step, without the need to use special emulsifier to be fitted in the percolating machines.
  • Another advantage lies in the fact that the capsule according to the present invention is recyclable, since its cover is removable and the content can easily be separated from the plastic part.

Abstract

L'invention concerne une capsule (10) pour des produits d'infusion, en particulier du café. La capsule (10) comprend : un corps en forme de coupelle (20) défini par une paroi latérale (21); et un couvercle (30) pour fermer le corps en forme de coupelle (20); le corps en forme de coupelle (20) étant pourvu d'une cloison de filtrage (25) d'un premier produit d'infusion (P1). La capsule (10) est caractérisée en ce qu'elle comprend, en aval de l'élément de filtrage (25), une poche (40) pour mélanger finement ledit premier produit d'infusion (PI) à l'air afin d'obtenir un second produit d'infusion (P2). En outre, la poche (40) permet de distribuer le second produit d'infusion (P2) vers l'extérieur de manière pulsée. La poche (40) est définie d'un côté par la cloison de filtrage (25) et de l'autre côté par une membrane élastiquement déformable (50) pourvue d'un conduit d'évacuation par impulsion (51) dudit second produit d'infusion (P2) contenant une quantité appréciable de crème de café.
