Definitions

  • An object of the present invention is a capsule for the preparation of infused or soluble beverages.
  • the object of the present invention is a capsule for the packaging of concentrated products (for example in the form of powder, granules, leaves) in predetermined and single-use dosage forms for the impromptu preparation of beverages (such as tea, coffee, herbal teas, milk, chocolate, etc.) by introducing a pressurized fluid (usually hot water) into the capsule itself.
  • concentrated products for example in the form of powder, granules, leaves
  • beverages such as tea, coffee, herbal teas, milk, chocolate, etc.
  • a pressurized fluid usually hot water
  • the common operating principle of such machines involves the perforation of the cover used to close the capsule to allow the introduction of a flow of hot water under pressure by means of the infuser assembly. Once the infusion of the extract contained within the capsule is achieved, the infused beverage flows out of the capsule and is directed by the machine into the cup or the final container.
  • the capsules are provided with a sealing film, usually made of aluminum, positioned at the bottom of the capsule on a base provided with one or more points or cutting or perforating profiles. Increasing the pressure inside the capsule causes the pressurized fluid to push the aluminum layer against the points on the base to cause perforation. Once an opening has been created in the sealing film layer, the infused beverage may flow out from a suitable opening at the base of the capsule itself.
  • a sealing film usually made of aluminum
  • capsules are quite complex from a construction point of view, especially with regard to making the points and the cutting and perforating profiles on the base. Therefore, the known capsules like for example from WO2015/ 121882 are quite expensive especially in terms of manufacturing the molds thereof.
  • the object of the present invention is to provide a capsule for the preparation of infused or soluble beverages that solves the problems of the known art.
  • the object of the present invention is to provide a capsule for the preparation of infused or soluble beverages that is simpler and more economical than the known capsules, while achieving similar performance in terms of the quality of the infused beverage.
  • Such object is achieved by a capsule wherein the opening for the outflow of the infused beverage occurs as a result of deformation of the sealing disc placed inside the capsule due to the pressure exerted by the pressurized fluid inside it, thus avoiding the use of any cutting or perforation means as in known capsules.
  • the object of the present invention is to obtain a homogeneous deformation of the sealing disc in order to assure the opening of the capsule.
  • a capsule for the preparation of infused or soluble beverages is shown, indicated at the reference number 1.
  • Capsule 1 comprises a body or cup 2 suitable for defining an internal volume V for containing at least one substance to be infused or dissolved, typically in powder or granular form.
  • the cup 2 is provided, on the one side, with a bottom 3 and, on the opposite side, with an inlet opening 21 defined by a protruding edge 4 extending outward.
  • the capsule 1 comprises a cover 6 fixed by bonding or welding to the edge 4 adapted to seal the cup 2 at the top.
  • the cup 2 is provided on the bottom 3 with an outlet opening 31, defined by a nozzle 32, adapted to allow the outflow of the infused beverage.
  • the cup 2 is provided on the bottom 3 with a base 33 provided with a plurality of reliefs 310, 320, 330, 340, 350, 360 projecting vertically with respect to the base 33 itself.
  • the top surface of the reliefs 310, 320, 330, 340, 350, 360 is substantially flat and devoid of cutting, puncture or tearing elements. Also, the reliefs 310, 320, 330, 340, 350, 360 have beveled and rounded edges.
  • the reliefs 310, 320, 330, 340, 350, 360 all have substantially the same vertical extension.
  • a sealing disc 5 is fixed, by bonding or welding, on the upper surface of at least some of the reliefs 310, 320, 330, 340, 360.
  • the base 33 comprises a central portion 310 defined by a first relief covering the output opening 31 of the nozzle 32.
  • the central portion 310 is provided with at least one connection opening 311 between the inside of the cup 2 and the outlet opening 31, to allow the flow of the infused beverage out of the capsule 1.
  • the central portion 310 comprises a plurality of connection openings 311.
  • the base 33 comprises a labyrinth 30 defined by at least one further relief 320, 330, 340.
  • the labyrinth 30 is of a substantially circular shape and disposed concentrically with respect to the nozzle 32 (and the central portion 310).
  • Each relief 320, 330, 340 of the labyrinth 30 is provided with a plurality of grooves 321, 331, 341, preferably diagonal, adapted to allow the infused beverage to flow out of the capsule 1.
  • the labyrinth 30 is defined by a first labyrinth portion 320, a second labyrinth portion 330, and a third labyrinth portion 340 arranged concentrically with respect to the nozzle 32.
  • the base 33 comprises an outer edge 360, defined by a further relief, whereon a sealing disc 5 is securely fixed by bonding or welding.
  • the base 33 comprises a collection compartment 352 for the infused beverage to flow out of the capsule 1.
  • the collection compartment 352 defines a space adapted to accommodate, without obstructing it, the deformation of at least one portion of a sealing disc 5 when the pressure exerted by the fluid within the capsule 1 reaches a certain threshold opening level. This choice of construction allows the disc 5 to deform freely within the collection compartment 352 so as to form at least one crease 52 adapted to open a passage P for the outflow of the infused beverage.
  • the base 33 also comprises a plurality of sectors 350, defined by further reliefs, arranged between the labyrinth 30 and the edge 360, within the collection compartment 351.
  • Circular sectors 350 are arranged circumferentially homogeneously with respect to the nozzle 32. Also the sectors 350 are beveled and provided with a substantially flat top surface devoid of cutting, puncture or tearing elements. A sealing disc 5 rests on the upper surface of the sectors 350.
  • the sectors 350 have substantially the same vertical extension as the other reliefs 310, 320, 330, 340 that form the base 33. In a different variant of embodiment, the sectors 350 have a lower vertical extension, i.e. they are lowered with respect to the other reliefs 310, 320, 330, 340 that form the base 33.
  • the sectors 350 define a plurality of compartments 351, or compartments or spaces, which allow the infused beverage to flow out of the capsule 1.
  • a compartment 351 is defined between a pair of adjacent sectors 350.
  • the compartment 351 defines a space adapted to accommodate, without obstructing it, the deformation of at least one portion of a sealing disc 5 when the pressure exerted by the fluid within the capsule 1 reaches a certain threshold opening level.
  • This choice of construction allows the disc 5 to deform freely within the compartment 351 so as to form at least one crease 52 adapted to open a passage P for the outflow of the infused beverage.
  • the presence of the sector 350 allows the disc 5 to be supported in such a way as to ensure that the passage P has an adequate width for the infused beverage to flow out correctly and easily.
  • the capsule 1 for preparing infused or soluble beverages comprises a sealing disc 5, fixed inside the cup 2 at the bottom 3, adapted to seal the cup 2 from below.
  • the disc 5 is positioned between the internal volume V and the reliefs 310, 320, 330, 340, 350, 360.
  • the capsule 1 is thus provided with a closed chamber 12, defined at the top by the cover 6 and at the bottom by the disc 5, within which the substance to be infused or dissolved is contained.
  • hermetically sealed chamber 12 allows the organoleptic properties of the substance to be infused or dissolved to be maintained over time and ensures an infused beverage of good quality.
  • An essential element for obtaining a hermetically sealed chamber 12 is the proper gas tightness of the system for fixing the sealing disc 5 within the capsule 1.
  • the sealing disc 5 is composed of an outer portion 51 and an inner portion 52, joined together, by welding or bonding, in a manner which is at least partially releasable.
  • the outer portion 51 is a ring surrounding the inner portion 52 in the form of a disc, joined together by welding or bonding in an at least partially releasable manner. As shown in figure 7B , the inner edge of the ring that forms the outer portion 51 overlaps the outer edge of the disc that forms the inner portion 52. In the overlap area 53, the two outer 51 and inner 52 portions that form the sealing disc 5 are joined in an at least partially releasable manner, i.e. by the use of a low-adhesion or weak lacquer 89, or bonded by means of a low-adhesion or weak adhesive. Such lacquer 89 allows the detachment or separation of the two outer 51 and inner 52 portions due to the increase of pressure inside the capsule 1.
  • the weak lacquer ensures a detachment force lower than that of standard lacquers.
  • the overlap area 53 between the outer 51 and inner 52 portions comprising the sealing disk 5 is positioned at a compartment 351,352 of the base 33.
  • the overlap area 53 is positioned at the collection compartment 352; in the embodiment of figure 10A , the overlap area 53 is positioned on at compartment 351 between two adjacent sectors 350.
  • the disc 5 is welded or bonded permanently to the base 33 of the cup 2, i.e. using a standard lacquer 88.
  • a standard lacquer 88 prevents the detachment or separation of the sealing disc 5 from the base 33.
  • the permanent welding between the disc 5 and the edge 360 of the base 33 of the cup 2 ensures an effective closure of the capsule so as to assure gas tightness.
  • the outer edge of the ring that forms the outer portion 51 is fixed to the outside edge 360 of the base 33, and the inner portion 52 is fixed to the labyrinth 30 or at least on the outermost relief 340 forming the labyrinth 30.
  • the disc 5 is permanently bonded or welded also to the central portion 310.
  • the disc 5 is only supported without being fixed to the sectors 350.
  • the sector 350 defines a support and sliding surface on the inner 52 and outer 51 portions of the disc 5 during its deformation by the pressurized fluid inside the capsule 1 when a certain opening pressure is reached.
  • the sectors 350 keep the disc 5 raised during deformation in such a way as to ensure that there is a free path for the infused beverage to flow out of the capsule 1.
  • the disc 5 is a durable aluminum film i.e. adapted to deform due to the increase in pressure within the capsule 1 without breaking or tearing.
  • the disc 5 is a film with a thickness between 25 ⁇ and 45 ⁇ and still more preferably between 30 ⁇ and 40 ⁇ .
  • the disc 5 is a film made of aluminum or a plastic/aluminum composite or plastic material, either single- or multilayer.
  • the cover 6 is a film made of a plastic/aluminum composite or plastic material, either single- or multilayer.
  • the cup 2 is made of plastic material, preferably injection molded or thermoformed.
  • the cup is made of polypropylene (PP), or polyethylene (PE), or polybutylene terephthalate (PBT), polyethylene terephthalate (PET).
  • a capsule according to the present invention may be used for the packaging of concentrated products (in the form of powder or granules or leaves) in predetermined and single-use doses, for the impromptu preparation of beverages such as leaf or soluble tea, powdered or instant coffee, herbal teas, milk, chocolate, or other dehydrated and soluble products.
  • concentrated products in the form of powder or granules or leaves
  • beverages such as leaf or soluble tea, powdered or instant coffee, herbal teas, milk, chocolate, or other dehydrated and soluble products.
  • the capsule 1 in its various variants of embodiment, may be used for the impromptu preparation of beverages (such as tea, coffee, herbal teas, milk, chocolate, etc.) by means of automatic or semi-automatic machines equipped with a dispensing unit adapted to produce an infusion via the passage of pressurized hot water through the capsule 1.
  • beverages such as tea, coffee, herbal teas, milk, chocolate, etc.
  • the capsule 1 is inserted into a suitable seat provided in the machine.
  • the machine perforates the cover 6, positioned to seal the capsule 1, and injects a pressurized fluid (typically hot water) into the chamber 12 wherein the substance 11 is contained.
  • a pressurized fluid typically hot water
  • the presence of the disc 5 to seal the bottom 3 of the capsule 1 allows the pressurized fluid to remain for a certain amount of time in contact with the substance 11 to be infused or dissolved to ensure an optimal infused beverage is obtained.
  • the pressure exerted by the fluid inside the capsule 1 rises to a certain threshold level or opening pressure (for example between 4 and 8 bar) which pushes on the disc 5 to cause the capsule 1 to open.
  • the infused beverage may flow out through the outlet opening 31 and be directed through the nozzle 32 into the cup or the final container.
  • the opening of the capsule 1 is determined by the at least partial deformation of the disc 5.
  • the disc 5 becomes slightly convex at the compartment 351, 352, i.e. in the overlap area 53 between the outer 51 and inner 52 portions.
  • the outer edge of the inner portion 52 rises slightly with respect to the inner edge of the outer portion 51.
  • the two portions 51, 52 detach or separate, at least partially, from each other. Such separation causes the sealing effect previously ensured by the sealing disc 5 to fail.
  • At least the outer edge of the inner portion 52, and preferably also the inner edge of the outer portion 51, is deformed with a certain buckling and forms at least one crease 54, and preferably a plurality of creases.
  • the deformation of the disc 5 at the overlap area 53, and in particular the crease 54, results in a separation between the outer 51 and inner 52 portions of the disc 5 so as to allow the opening of a passage P for the outflow of the infused liquid.
  • the creases 54 are formed at the compartments 351, 352.
  • the disc 5 simply rests on the upper surface of the sectors 350 without being welded or bonded to them, it may slide freely over the sectors 350 during deformation due to the increase in pressure within the capsule 1.
  • Such a technical solution allows the disc 5 to deform without tearing or breaking.
  • the outlet passage P for the infused beverage is created spontaneously between the chamber 12 and the nozzle 32 by only the increase in pressure exerted by the pressurized fluid inside the capsule 1 without needing means for perforating or tearing the disc, such as points or sharp profiles.
  • An object of the present invention is therefore a capsule 1 for the preparation of infused or soluble beverages, comprising:
  • the deformation of the disc 5 determines, at least in a compartment 351, 352 provided in the base 33 of the capsule 1, at least one crease 54 adapted to define a passage P, between the portions 51,52 that compose the disc 5, for the outflow of the infused beverage.
  • An object of the present invention is also a method for preparing an infused beverage by means of a capsule 1 according to the present invention, wherein the opening for the outflow of the infused beverage is obtained by the deformation of the disc 5 due to pressure, a deformation that causes at least a partial separation of the portions 51,52 that compose the disc 5 so as to cause the sealing effect previously ensured by the disc 5 itself to fail.
  • a capsule for the preparation of infused or soluble beverages according to the present invention is simple in construction and in any case may ensure high performance in terms of the quality of the infused beverage.
  • the opening for the outflow of the infused beverage occurs as a result of the deformation of the sealing disc covering the bottom due to the pressure exerted by the fluid inside the capsule, thus avoiding the use of any cutting or perforation means.
  • the deformation occurs exclusively at an inner portion of the disc itself, i.e. in the overlap area 53 between the inner portion 52 and the outer portion 51 forming the disc.
  • the sealing disc is thus made in such a way as to ensure the gas tightness and at the same time in such a way as to be provided with an area of yield which is able to deform and open due the pressure inside the capsule.
  • the disc being secured to the base exclusively by means of permanent welding (at the edge 360 and the labyrinth 30), it is surely able to ensure an effective and long-lasting gas tightness.
  • a capsule thus made allows the organoleptic properties of the substance contained within to be maintained over time, thus ensuring an infused beverage of an excellent quality.
