Definitions

  • the present invention relates to a capsule for preparing a beverage.
  • the present invention relates to a capsule comprising a cup-shaped body, which is adapted to contain a dose of a substance to be brewed, has a longitudinal axis and comprises a lateral wall coaxial with the axis, a bottom wall, and a tubular appendage extending from the bottom wall towards the inside of the capsule and defining a beverage outflow channel.
  • the capsule is also provided with a cover to close the cup-shaped body, and the tubular appendage has a first axial end facing the cover and defining the inlet of the beverage outflow channel, and a second axial end defining the outlet of the beverage outflow channel.
  • capsules are known, for example, from EP 0 057 671 B l and WO 2015/124526.
  • the main function of the tubular appendage in this type of capsule is to improve the so-called pre-brewing phase by a greater diffusion of the brewing fluid in the substance to be brewed; in fact, the fluid supplied into the capsule through the cover is forced to follow a descending and ascending winding path before flowing out of the capsule through the tubular appendage.
  • WO 2015/124526 unsatisfactorily addresses the dripping problem by providing a tubular appendage closed at the top end by a wall formed in one piece with the lateral wall of the tubular appendage and provided with an orifice suitably sized to limit the dripping.
  • the orifice is formed in a rigid wall results in the orifice remaining permanently open and, hence, being prone to clogging by solid substance particles, so compromising the beverage delivery.
  • the object of the present invention is to provide an improved capsule of the above-described type capable of overcoming the above-described drawbacks and, at the same time, being easy and inexpensive to manufacture.
  • a capsule for producing a beverage is provided, as claimed in claim 1, and, preferably, in any one of the claims directly or indirectly dependent on claim 1.

  • FIG. 5 shows a few embodiments of the membrane shown in Figure 4.
  • reference numeral 1 indicates, as a whole, a capsule adapted to contain a substance for producing brewing beverages, such as, coffee, tea, cocoa, milk, broth, etc.
  • the capsule 1 is adapted to be used in well-known brewing devices (not shown), where the brewing process comprises sealing the capsule in a seat and supplying in the capsule a warm or cold pressurised fluid, usually water, so that the substance in the capsule may percolate under pressure, thereby producing the relevant beverage.
  • a warm or cold pressurised fluid usually water
  • the capsule 1 comprises an outer casing defined by a cup-shaped body 2 having a longitudinal axis 3, and by a cover 4, which consists of a film made of one or more layers of plastic and/or metal material and is seal-welded to an annular flange 5 arranged at the open end of the cup-shaped body 2 and extending from the cup-shaped body 2 towards the outside transversely to the axis 3.
  • a cover 4 which consists of a film made of one or more layers of plastic and/or metal material and is seal-welded to an annular flange 5 arranged at the open end of the cup-shaped body 2 and extending from the cup-shaped body 2 towards the outside transversely to the axis 3.
  • the cup-shaped body 2 comprises a lateral wall 6, which is coaxial with the axis 3, is provided at a top axial end thereof with said flange 5, and is preferably provided with a plurality of reinforcing sunken portions 7 evenly distributed around the axis 3.
  • the cup-shaped body 2 also comprises a bottom wall 8 connected to the lower axial end of the lateral wall 6 and is provided with a tubular appendage 9, which extends, at least partially, inside the capsule 1 coaxially with the axis 3 and defines, at an axial end thereof facing the outside of the capsule 1, a beverage dispensing nozzle 10.
  • the bottom wall 8 comprises a peripheral annular portion 11 generally convex in shape towards the exterior of the capsule 1 and connected to the lateral wall 6 directly or, preferably, by means of a flat annular portion 12 transverse to the axis 3.
  • the bottom wall 8 further comprises a central tubular portion 13, which extends coaxially with the axis 3 from an inner peripheral edge of the annular portion 11 and is connected, at the opposite end, to the tubular appendage 9.
  • the central portion 13 has a concave frustoconical shape, which is tapered towards the inside of the capsule 1 so as to protrude beyond the rest of the bottom wall 8 inside the capsule 1.
  • the tubular appendage 9 extends through the central portion 13, and has an inner section 14, which prolongs from the bottom wall 8 towards the inside of the capsule 1, and an outer section 15, which prolongs from the bottom wall 8 towards the outside of the capsule 1 and defines, with the inner section 14, a beverage outflow channel 16.
  • the beverage outflow channel 16 has an intermediate converging portion 17, which is arranged immediately upstream from a cylindrical or diverging end portion 18, defines, together with the end portion 18, the above-mentioned beverage dispensing nozzle 10, and has the function, during use, of conveying towards the centre of the channel 16 the beverage that flows through the tubular appendage 9, so that the beverage exits the end portion 18 in the form of a compact stream.
  • the end portion 18 is also preferably provided with an axial insert 19 integrally connected to the lateral wall of the outer section 15 by means of radial baffles 20 - three in the example shown - configured to split the end portion 18 into respective separate ducts 21, which further improve the guidance of the output flow and prevent the formation of splashes.
  • the intermediate converging portion 17 has a length, with respect to the total length of the beverage outflow channel 16, that is sufficient to ensure the above-described flow "compacting" effect.
  • its length is at least equal to about 1/3 of the total length of the beverage outflow channel 16.
  • the need to have a sufficiently long converging section is met by means of appropriately selecting the shape and geometry of the capsule 1.
  • the cup-shaped body 2 is obtained by injection moulding of thermoplastic material for food use, in particular polypropylene (PP) or polybutylene terephthalate (PBT), and therefore the lateral wall 6, the bottom wall 8 and the tubular appendage 9 are formed in one piece.
  • thermoplastic material for food use in particular polypropylene (PP) or polybutylene terephthalate (PBT)

  • the intermediate converging portion 17 of the channel 16 is defined by a respective converging portion of the outer section 15, and the inner section channel 16 have a cylindrical shape coaxial with the axis 3.
  • the inner section 14 extends inside the capsule 1, preferably up to about 2/3 of the height of the lateral wall 6, and defines, with the lateral wall 6 and the bottom wall 8, an annular volume 22 adapted to contain the substance to be brewed.
  • the function of the tubular appendage 9 is to make sure that, in use, the pressurised hot or cold water supplied into the capsule 1 through the cover 9, by means of one or more known perforating member, does not reach the exit directly by flowing from the top to the bottom through the substance to be brewed, but, in order to exit the capsule 1, goes back from the bottom to the top and reaches the end of the tubular appendage 9, creating, within the capsule 1, turbulent movements which promote a capillary penetration of the fluid into the substance to be brewed.
  • the free end of the tubular appendage 9 is provided with a membrane 23 configured to allow the beverage to flow through the beverage outflow channel 16 only when the pressure inside the capsule 1 reaches a predetermined threshold value.
  • the membrane 23 is obtained from a film of polymeric material welded to the free edge of the inner end of the tubular appendage 9 and has a plurality of through micro-slots 24, whose size, shape and arrangement may vary as a function of the type of beverage to be dispensed.
  • Figure 5 illustrates a few possible embodiments of micro slots 24.
  • the micro-slots 24 allow or inhibit the outflow of the beverage from the capsule 1 depending on the pressure conditions inside the same.
  • the flaps of the micro- slots 24 are normally close together and during the wrapping, packaging, storage and transport steps they prevent leakage of soluble powder from the capsule 1.
  • the increase in pressure inside the capsule 1 itself following the feeding of the pressurised water causes the separation of the flaps of each of the micro-slots 24 which, by opening, allow the passage of the beverage inside the channel 16. Therefore, the morphology of the micro- slots 24 determines the threshold value of the internal pressure, at which the flaps of the micro slots 24 bend, and thus contributes to the adjustment of the pressure inside the capsule 1 and of the flow rate of the beverage.
  • the membrane 23 is obtained from a multilayer sheet comprising a thin sheet of metallic material, for example aluminium or other well- known alloys, and a plastic film which is similar to the plastic film with micro slots previously described with reference to the attached figures, and stably connected to the sheet of metallic material.
  • the membrane 23 is welded or glued, on the side of the metal sheet, to the free edge of the tubular appendage 9 so as to seal the capsule 1, while the micro-cut plastic film is facing the inside of the capsule 1.
  • the increase in pressure inside the capsule 1 following the feeding of the pressurised water causes widening of the micro slots and tearing of the metal sheet at the micro slots, with consequent outflow of the beverage through the channel 16.
