Definitions

• the present invention generally relates to the preparation of infused beverages such as coffee, chocolate, tea, herbal teas and the like starting from disposable capsules and in particular to a disposable single-dose or multi-dose capsule to be used in machines for infused beverages.
• Disposable capsules used in dispensing machines for infused beverages contain a food product in a granular or particulate form, for example coffee. It is known that a beverage is obtained through an "infusion" process, whereby a capsule containing the food product is crossed by an infusion liquid, typically water, which is supplied under pressure and at a high temperature. The infusion liquid coming out from the capsule is enriched by the aroma of the food product and forms the desired beverage, which is suitably channeled within a dispensing machine and served by a dispensing head thereof.
• infusion liquid typically water
• Disposable capsules typically comprise a frustum-shaped hollow body whose open top has a flange on which a cover generally formed by a gas-tight film is applied.
• the cover serves to seal the cavity of the frustum-shaped body so as to allow to preserve of the food product contained therein over time.
• a capsule In use, a capsule is fitted in a brewing chamber of a dispensing machine for infused beverages and subsequently perforated by way of special drills on the top sealed by the cover. Perforation of the bottom may also be carried out depending on the type of capsule.
• the hole or holes so made allow passage of a flow of liquid through the capsule from one of its ends to the opposite end.
• infused beverages such as e.g. cappuccino that have more than one ingredient
• These capsules must be used in a precise sequence according to the recipe for the preparation of the specific beverage.
• the preparation of infused beverages comprising more than one ingredient from disposable capsules is therefore expensive and uncomfortable for a user.
• each compartment contains a single food product in a granular or particulate form and is provided with a respective dispensing opening. Injection of an infusion liquid into the compartments is carried out in a sequential manner e.g. by employing respective injector needles, thus allowing to dispense the infused beverages obtainable from each food product according to a predefined sequence, suitable to prepare the desired final beverage.
• Multiple-compartment capsules can be improved as far as their inner structure, as well as the injection sequence of the food products contained in their compartments are concerned.
• the technical problem posed and solved by the present invention is therefore to provide a disposable capsule for dispensing machines of infused beverages that allows to overcome the drawbacks mentioned above with reference to the prior art.
• An idea of solution underlying the invention is to make a capsule whose body comprises a main cavity containing a first food product, as well as at least one inner cavity or chamber that is separated from the main cavity and contains a second food product.
• the main cavity and the at least one inner cavity or chamber are provided with respective openings for the dispensing of an infused beverage obtained by supplying an infusion liquid into each of them.
• the capsule also comprises closing means of one of the dispensing openings, which can be selectively activated upon emptying of the food product contained in the respective cavity or chamber.
• the cavities or chambers are put in fluid communication with each other through a plurality of apertures through which the infusion liquid is made to flow upon the activation of the closing means.
• the capsule according to the invention allows the infusion of the food products contained in its separate cavities or chambers, as well as the dispensing of the respective beverages, in a sequential manner without the need to pierce the cover of the capsule at multiple locations, nor to employ and sequentially manage separate flows of infusion liquid, which results in a considerable constructional simplification of the infusion unit of a machine for dispensing infused beverages that receives the capsule.
• the capsule according to the invention can manage autonomously and in a sequential manner the infusion of the food products contained therein and the resulting dispensing of the infused beverage, and can therefore be employed in infusion units of a traditional type.
• the closing means are formed by a shaped body, preferably having a spherical shape, which is configured to tightly engage the dispensing opening.
• the shaped element is made of a material having a density higher than that of water and lower than that of the food product contained in the respective cavity or chamber. This allows the shaped element to float in the infused beverage when it is dispensed through the dispensing opening of the cavity or chamber and to subsequently close the dispensing opening when the cavity or chamber is filled by the infusion liquid.
• FIG. 1 is a perspective view showing a capsule according to the present invention for the preparation of infused beverages
• FIG. 2 is a perspective, exploded view showing a longitudinal section of the capsule of figure 1;
• FIG. 3 is a perspective, exploded view that schematically shows a longitudinal section of the capsule of figure 1, in whose cavities or chambers respective food products in a granular or particulate form are present;
• FIG. 4 is a perspective, exploded view showing a longitudinal section of a capsule according to an alternative embodiment of the invention.
• figure 5 is a perspective, exploded view similar to the view of figure 4, which shows the cavities of the capsule filled with respective food products in a granular or particulate form.
• a disposable capsule according to the invention is generally indicated by reference number 100.
• the capsule 100 comprises a substantially frustum-shaped body 110 having an axis A, in turn comprising a main cavity 111 delimited by a bottom wall 112 and by a peripheral wall 113.
• the body 110 also includes a flange 114 formed along a top edge of the peripheral wall 113.
• the main cavity 11 1 contains a measured dose of a first food product FP1 in a granular or particulate form, for example milk powder.
• the capsule 100 further comprises a cover 120, e.g. made of a polylaminate material, tightly fixed on the flange 114 so as to allow to preserve over time the food product contained in the main cavity 111.
• a cover 120 e.g. made of a polylaminate material
• the body 110 also includes a first dispensing opening 115 e.g. formed in the bottom wall 112 and configured to allow to dispense a first infused beverage obtained by making an infusion liquid, typically water, to flow through the main cavity 111 from an opening formed in the cover 120 towards the bottom wall 112.
• a first dispensing opening 115 e.g. formed in the bottom wall 112 and configured to allow to dispense a first infused beverage obtained by making an infusion liquid, typically water, to flow through the main cavity 111 from an opening formed in the cover 120 towards the bottom wall 112.
• the first dispensing opening 115 may advantageously comprise a filter element
• the filter element 115a for example a mesh filter, configured to prevent particles or granules of the first food product FP1 from exiting from the cavity.
• the filter element 115a may be advantageously integrally formed with the body 1 10 of the capsule 100.
• At least one inner cavity or chamber 116 is formed in the cavity 111 of the body 110.
• a measured dose of a second food product FP2 which is also in a granular or particulate form, is contained in the inner cavity or chamber 116 in a ready-to-use configuration of the capsule 100.
• the second food product FP2, e.g. coffee powder, is different from the first food product FP1.
• the inner cavity or chamber 116 comprises a second dispensing opening 117. In the embodiment of the capsule shown in figures 1 and 2 the second dispensing opening 117 is e.g. formed in the bottom wall 112 of the body 110 where the inner chamber 116 is located.
• the inner cavity or chamber 116 extends in the axial direction of the body 110 from the bottom wall 112 to the flange 114 and a top edge 116a of the inner chamber 116 is tightly fixed to the cover 120. It is thus possible to ensure a complete separation between the inner cavity or chamber 116 and the main cavity 11 1, thus avoiding that the two food products contained in the capsule 100 are mixed with each other.
• a single inner cavity or chamber is formed in the capsule 100, for example having a substantially cylindrical shape arranged coaxially to the cavity of the body 110.
• the inner cavity or chamber 116 might also be formed by exploiting a part of the peripheral wall 113 of the body 110 of the capsule 100 by providing a partition wall along a secant plane parallel to the axis A. Additional inner cavities or chambers separated by respective partition walls might also be provided.
• the configuration of the capsule 100 according to the invention is such that, by making an infusion liquid, for example water, to flow into the inner chamber 116 of the capsule 100 it is possible to obtain a second infused beverage, which is dispensed through the second dispensing opening 117 in a completely independent way relative to the dispensing of the first infused beverage.
• This configuration of the capsule 100 thus allows to prepare a multiple ingredient beverage, such as e.g. a cappuccino.
• the second dispensing opening 117 may advantageously comprise a filter element 118 having a planar shape and arranged in the inner chamber 116 so as to prevent escape of particles or granules of the second food product FP2.
• a plurality of ribs 117a may advantageously be formed in the second dispensing opening 117.
• the ribs extend in the direction of the axis A of the capsule 100 and are e.g. arranged radially.
• the ribs 117a allow to divide the flow of an infused beverage obtained by making the infusion liquid to flow through the second food product FP2 into a plurality of parallel streams having a reduced pressure.
• the ribs 117a may advantageously be formed integrally with the body 110 of the capsule 100.
• the capsule 100 further comprises closing means of one between the first dispensing opening 115 and the second dispensing opening 117, which can be selectively activated as a result of the emptying of the first food product FP1 or of the second food product FP2 contained in the main cavity 111 and in the inner cavity or chamber 116, respectively.
• the top edge 116a of the inner cavity or chamber 116 comprises a plurality of slits 116b that put the inner cavity or chamber 116a in fluid communication with the main cavity 111.
• the configuration of the capsule 100 according to the invention is such that, upon emptying of the first food product FP1 or of the second food product FP2 one between the first dispensing opening 115 and the second dispensing opening 117 is closed by the closing means and the infusion liquid progressively fills the main cavity 111 or the inner cavity or chamber 116 up to the top edge 116a. Once reached the top edge 116a, which is tightly fixed to the cover 120, the infusion liquid is forced to pass from one cavity to the other one through the slits 116b, thus reaching the food product contained therein and allowing infusion and dispensing of the resulting infused beverage through the respective dispensing opening.
• the infusion of the two food products FP1, FP2 and dispensing of the two resulting beverages takes place in a sequential manner without the need to pierce the cover 120 of the capsule 100 at two locations and to employ two separate flows of infusion liquid.
• the configuration of the capsule according to the invention may be used in an infusion unit of a conventional type as far as perforation of the capsule cover and the dispensing of the infusion liquid are concerned.
• the closing means are associated with the main cavity 111, being it clear that the closing means may be associated in a completely equivalent manner to the inner cavity or chamber 116.
• the closing means are made up of a shaped element 130 configured to tightly engage the first dispensing opening 115.
• the shaped element 130 is made of a material having a density higher than that of water and lower than that of the first food product FPl contained in the cavity 111. This allows the shaped element 130 to float in the first infused beverage when it flows out through the first dispensing opening 115 and to subsequently sink in the infusion liquid thus closing the first dispensing opening 115.
• a tight seal is achieved both thanks to the contour of the shaped element 130 and to the pressure of the infusion liquid fed into the cavity 111 of the capsule 100.
• the shaped element 130 is for example a sphere, which offers the advantage of providing a good seal independently of the position of the shaped element 130 relative to the first dispensing opening 115.
• the bottom wall 112 of the cavity 111 is inclined with respect to the axis A of the body 110 of the capsule 100 and the first dispensing opening 115 is formed at the farthest portion of the bottom wall 112 relative to the flange 114, i.e. at the lowest portion of the cavity 111 when the capsule is in a vertical position, as it is typically used.
• This configuration facilitates the spherical shaped element 130 to move towards the first dispensing opening 115, because the force of gravity is added to the force generated by the pressure of the infusion liquid.
• closing means of the type described above may be provided in each inner cavity or chamber, thereby enabling to replicate the sequential infusion mechanism from one chamber to the adjacent one, once infusion of the respective food product is completed.
• the capsule 100 comprises a body 110 substantially frustum-shaped having an axis A, in turn comprising a main cavity 111, a bottom wall 112 and a peripheral wall 113.
• the body 110 also comprises a flange 114 formed along a top edge of the peripheral wall 113.
• the main cavity 111 contains a measured dose of a first food product FP1 in a granular or particulate form, for example milk powder.
• the capsule 100 further comprises a cover 120, e.g. made of a polylaminate material, tightly fixed on the flange 114 so as to allow to preserve over time the food product contained in the main cavity 111.
• a cover 120 e.g. made of a polylaminate material
• the capsule 100 also comprises an inner cavity or chamber 116 arranged coaxially to the main cavity 111 and separated therefrom by a wall 111a that forms a bottom of the main cavity 111.
• a first dispensing opening 115 is formed in the bottom wall 111a of the main cavity 111 and a plurality of micro apertures 11 lb are formed as well.
• a second food product FP2 in a granular or particulate form e.g. coffee
• a second dispensing opening 117 for the dispensing of an infused beverage obtainable by making an infusion liquid to flow through the inner cavity or chamber 116 is formed in the bottom wall 112 of the body 110 of the capsule 100, as it will be described in greater detail in the following.
• the bottom wall 112 is sealed by a gas- impermeable film (not shown).
• the second dispensing opening 117 is e.g. arranged at the axis A of the body 110 of the capsule 100.
• the capsule 100 also comprises an insert 200 made up of a stem 210 extending in the direction of the axis A of the capsule 100 and a frustum-shaped base 220 that rests on the bottom wall 112.
• the stem 210 extends axially from the base 220 beyond the flange 114 whereby in a packaged or ready-to-use configuration of the capsule 100 the cover 120 is deformed outwards and features a conical shape.
• the stem 210 comprises a base 210a tightly fitted in the first dispensing opening 115 and a protruding portion 210b extending axially and contacting the cover 120.
• the stem 210 also comprises a sharpened portion 211 that protrudes axially from the cavity defined by the frustum-shaped base 220 and thus faces the bottom wall 112 of the capsule 100, which is sealed by a gas-impermeable film F.
• the base 210a of the stem 210 and the sharpened portion 211 thereof are hollow and comprise a through cavity 212 configured to allow dispensing from the capsule 100 of the first beverage obtainable in the main cavity or chamber 111, as it will be described in greater detail in the following.
• the frustum-shaped base 220 comprises a plurality of micro-apertures 221 having a size comparable to the food product contained in the capsule 100 and has protruding portions 222 having a reduced thickness in the form of circumferential grooves.
• the capsule 100 also comprises closing means of one between the first dispensing opening 115 and the second dispensing opening 117, that may selectively be activated upon emptying of the first food product FP1 or the second food product FP2 contained in the main cavity 111 and in the inner cavity or chamber 116, respectively.
• the closing means are made up of a shaped element 130 advantageously having a spherical shape.
• the shaped element 130 is arranged in the main cavity or chamber 111 and is intended to close the first dispensing opening 115.
• the capsule is fitted in an infusion unit of a machine for the dispensing of infused beverages.
• the cover 120 is compressed thus causing the stem 210 of the insert 200 to move axially.
• the frustum-shaped base 220 is consequently flattened onto the bottom wall 112 of the body 110 of the capsule 100.
• the movement of the base is facilitated by the circumferential grooves 222.
• the portion 211 of the stem 210 thus penetrates the film sealing the bottom wall 112 and tears it while being fitted in the opening 117 formed there.
• the main cavity or chamber 111 is thus in fluid communication with the outer environment through the dispensing opening 115 and the through cavity 212 formed in the base 210a of the stem 210.
• the density and compaction degree of the first and the second food product FP1, FP2 are such that the flow of the first beverage through the micro apertures 111b formed in the wall dividing the main cavity or chamber 111 from underlying the inner cavity or chamber 116 is substantially negligible.
• the shaped element 130 is fitted in the through cavity 212 thereby closing the first dispensing opening 115.
