Definitions

  • the present invention relates to a process, a device and a single serve capsule for the preparation of beverages. More particularly, the invention relates to a method, a device and a single serve capsule for the preparation of beverages such as carried out in machines provided with a dispensing group intended for receiving a capsule of food preparation in order to obtain hot beverages such as coffee, cappuccino, tea or the like.
  • the food preparation can be a soluble preparation or a product to be brewed such as ground coffee, tea and herbal remedies.
  • the assemblies intended for the preparation and the dispensing of beverages generally comprise a dispensing device having a seat receiving a single serve capsule.
  • the dispensing device is generally provided with a puncturing member or other means that opens one or more holes in at least one wall of the capsule, e.g. outlet holes on its bottom to provide an outlet for the beverage.
  • a puncturing member or other means that opens one or more holes in at least one wall of the capsule, e.g. outlet holes on its bottom to provide an outlet for the beverage.
  • an inlet hole for the liquid used to make the beverage that is usually hot water
  • WO02/076270 discloses this type of embodiment.
  • US 5 242 702 discloses a capsule in aluminium or plastic that is provided with a filter and a capsule dispensing wall, adjacent to the filter, that is able to withstand the internal pressure of the capsule (during the brewing step) while deforming without tearing.
  • a finger is positioned close to the deformable dispensing wall to open the said wall when the wall is deformed enough to reach the finger.
  • the capsule is located in its seat and pressurized hot water is fed inside the capsule to deform outwardly the bottom wall; a piston member pushes inwards a outlet lid provided on the bottom wall to form a permanent outlet for the beverage, the outlet lid being able to remain open also at the end of the dispensing step.
  • a good dispensing group must ensure complete and uniform solubilisation (or suspension/dispersion) of the whole product or of those parts of the product that upon brewing or infusion are solublized into the hot water and a good final appearance of the beverage; for coffee and cappuccino, a good final appearance means having a "froth", i.e. a layer of foam made of small bubbles, which is lasting and in an appreciable amount. This result is difficult to obtain because the shape and size of the capsules are the same for all the dispensable products, whereas the amount of soluble product provided within a capsule changes according to its nature.
  • 1.5 grams of product are provided when the beverage to be dispensed is espresso coffee from a soluble espresso preparation, about 3,0 grams for tea leaves, about 6,5 grams when the product is ground coffee, and 15-16 grams, or more, of product are provided within the same capsule when the beverage is soluble hot-chocolate or cappuccino. This difference in quantities is reflected in the possible difficulty in consistently obtaining the required amount and quality of foam for each beverage.
  • This embodiment has drawbacks in that it does not operate in a reproducible and constant way and suffers from the above described problems regarding the blockage of the channels and their possible contamination with bacteria due to the formation of films and accumulations of residues within the channels. Furthermore, the capsule is complex and expensive to manufacture in view of the way the outlet lid is obtained within the bottom wall.
  • the object of the present invention is to solve the aforementioned problems and to ensure constant and optimal results, from the point of view of the quality of the dispensed beverage.
  • Another object is to provide a capsule and a capsule-supporting assembly that have no hygiene problems.
  • the opening area is corresponding to the flow section of the beverage.
  • Variation of the dispensing area occurs following the step of forming the dispensing opening, i.e. after an opening has been formed.
  • the invention advantageously provides that said adjustment of the dispensing opening area is obtained by means of the pressure generated within said capsule by the liquid fed into the said capsule.
  • the opening can be formed from outside towards inside or viceversa. In the first case a puncture member faces a outlet lid portion of the bottom of the capsule inside the capsule, in the second case the opening lid portion of the bottom is pushed outwards by the build-up of pressure within the capsule.
  • a passage i.e. an opening
  • This opening is then enlarged by the action of pressure exerted by the water pumped into the capsule. Because the opening area has been increased, a greater amount of liquid flows through the opening and the pressure within the capsule decreases. The consequence of the pressure decreasing is that because of the bottom wall material and/or design, the bottom wall moves back to an at least partially closed position, generally towards its initial position, i.e. the opening area becomes smaller (decreases).
  • a further object of the invention is a capsule for implementing the method according to the invention, characterized according to claim 5.
  • the means for varying said dispensing opening comprise hinge means provided on the capsule wall where said opening is formed, and located between said dispensing opening and the capsule body in order to impart an oscillating movement to said wall during said dispensing step.
  • such "hinge” is obtained by having different thicknesses of the dispensing wall: in particular, the thickness in the area surrounding and adjacent to the dispensing opening is greater than the thickness of the same wall adjacent to the side walls i.e. adjacent to the capsule body.
  • a further object of the invention is a capsule wherein at least part of the dispensing wall has a rigidity within the range of 5 to 60 N/mm measured by compression with a punch and the deflection set to 3 mm; with these values, a wall elasticity is obtained which enables the required movement.
  • the capsule of the invention provides that said hinge is located at the portion and that it is elastically deformable, i.e. that such outlet lid portion, is biased by the hinge to return to a substantially closed position as pressure within the capsule has decreased.
  • the outlet lid may be open either inwardly or outwardly to the capsule.
  • the hinge means acts elastically or visco-elastically to control the flow of the beverage as if a valve means is provided in the capsule: the area of the opening 11 increases and decreases with the increase or decrease of the pressure in the capsule, even if and when there is no direct or proportional correlation between pressure and opening area 11.
  • the capsule is provided with filter means to retain the ground, spent, coffee, tea or other product, within the capsule upon brewing a beverage.
  • the filter is spaced from the bottom wall by means of a spacer.
  • the capsule 1, object of the invention comprises of a portion 1a having a generally concave shape and comprising a capsule body having a generally cylindrical side wall L, and a dispensing wall F which, in the shown embodiment, is the capsule bottom wall.
  • a circular outlet lid portion 1 b which can be open e.g. by a puncturing element, or piston 9, 9a of a dispensing group 10 or 10a ( figs. 5 and 10 ) in order to form a dispensing opening.
  • the outlet lid portion 1 b is obtained on capsule 1 by defining a fracture line 3 and a hinge 4 on the bottom of the capsule 1.
  • the capsule has means for varying the dispensing opening area, i.e. for increasing and decreasing the dispensing cross sectional area so as to vary the outflow of beverage from the capsule.
  • Such adjustment is obtained by making use of the pressurising action exerted by the liquid on the capsule wall F after dispensing step is started and the water is pumped into the capsule.
  • the pressure within the capsule increases: once a sufficient pressure value is reached, a dispensing opening is formed through which the product is partially dispensed.
  • the opening area increases to a maximum value.
  • the pressure within the capsule decreases, as well as the beverage dispensing area; this decrease leads to a new increase in pressure which in turn results in a new increase of the opening area.
  • both outlet lid part 1b of capsule 1, and fracture line 3 are circular; they may nevertheless have different shapes, for example ellipsoidal or with other kinds of fracture lines 3, depending on the type of piston used, the shape to be obtained for the opening in the bottom of capsule 1 and the type of dispensing opening to be obtained between the piston and the capsule wall F.
  • such opening is only present during dispensing: in this case reference is made to "zero or negative interference" between the piston and opening 1b, i.e. the piston portion which is engaged by the opening has a cross sectional area which is substantially equal to or greater than that of the opening.
  • substantially equal cross section is meant that at most the total air gap between the piston and the bottom of the capsule is about 1.0 mm and is preferably within the range of 0.01 to 0.5 mm.
  • Figures 5-8 show an embodiment of the invention wherein the capsule is engaged by a puncturing member 9 of a dispensing group 10.
  • the puncturing member 9 is slightly larger than opening 1b.
  • the ratio D1/D2 wherein D1 is the diameter of the cylindrical member where it engages the bottom wall F and D2 is the diameter of opening 1b, is within the range of 1.0 to 1.067, preferably within 1.01 to 1.03.
  • the difference between the puncturing member and the dispensing opening diameters is at most 2.0 mm, preferably 1.1 mm and more preferably between 0.05 and 0.8 mm. This means that soon after the puncturing member has been fitted into the dispensing opening there occurs what is shown in fig. 6 : the dispensing opening edges adhere to the puncturing member and are drawn towards the inside of the capsule.
  • opening 11 Upon formation of opening 11 an amount of beverage is dispensed from the capsule and the pressure drops: the bottom wall, no longer stressed by the same force, tends to return to the initial position in which it was adherent to the puncturing member and the opening area 11 is reduced in size in a greater or smaller rate in accordance with the nature of the wall F and the pressure still present within the capsule, possibly even reaching a very low value or substantially equal to zero. This condition is outlined in fig. 8 .
  • the additional liquid fed into the capsule causes the pressure therein to increase again until a wider opening area and increased beverage dispensing flow rate are obtained and the condition of the capsule is similar to the previous one, outlined in fig. 7 .
  • the dispensing wall of the capsule i.e. the bottom wall F
  • Preferred rigidity ranges are 10 to 50 N/mm and 20 to 45 N/mm.
  • the above mentioned rigidity is measured as shown in fig. 4 and below described, and the values set out herein refer to this measurement method.
  • Capsule 1, without outlet lid portion 1b, is placed upside down on the rigid plane of a dynamometer, the bottom F is assimilated with a membrane with a central perforation.
  • the measurement of rigidity is carried out by using a metallic punch 6 comprising a lower cylindrical portion 6a having a diameter corresponding to the nominal diameter of the opening obtained by removing the bottom piece 1b, and an upper cylindrical portion 6b with a diameter 2 mm greater than the diameter of portion 6a.
  • punch 6 is centred on the opening in the capsule bottom wall F and engages this wall F by a circular crown of 1 mm.
  • the measurement is performed on the dynamometer at a test velocity of 2 mm/min at a temperature of 23 °C, with deflection set to 3 mm.
  • the claimed rigidity is within the range of 5 to 60 N/mm, preferably 10 to 50 N/mm and more preferably 20 to 45 N/mm.
  • the dispensing wall F is provided with hinge means.
  • the hinge means can be implemented in several ways, according to the way the opening in bottom wall F is obtained.
  • hinge means are obtained in the bottom wall F.
  • capsule 1 has bottom wall where the thickness around, i.e. adjacent, the opening defined by portion 1b, for example in 8, is greater than the thickness, measured along the same cross section, adjacent side wall 1 a, for example in 7, in order to obtain the required hinge.
  • This difference in thickness is preferably obtained by increasing or decreasing the thickness value from 7 to 8, but may also be obtained in a discontinuous manner, for example by means of a rib 2 ( fig. 1 ) located adjacent to portion 1 b.
  • a further object of this invention is a capsule of the above described type characterised in that it has hinge means allowing alternate inward and outward motion of the dispensing wall, as a function of the pressure within said capsule during beverage dispensing from said capsule.
  • the position of the hinge substantially corresponds to the point of the bottom F where thickness is lowest, said point, as above specified, is preferably positioned adjacent the side wall L or between said wall and the midpoint between the wall L ( fig.4 ), or portion 1 a thereof ( fig.1 ), and the edge 3 of the bottom, or dispensing, wall F.
  • the side wall L of portion 1a connects with the bottom wall of capsule 1, where portion 1b is located, by means of an inner surface 5 shaped according to a curve and preferably, according to a circular arch.
  • the radius of said arch preferably is within the range of 3 to 15 mm and more preferably of 5 to 12 mm.
  • a rib 2 is provided outside and close to fracture line 3, with the purpose of having a thicker capsule bottom as described above, and of preventing the bottom of the capsule 1 from being excessively deformed within opening 1b during the opening step of the same by the perforating piston and particularly during the beverage dispensing step.
  • the rib 2 as in the embodiment shown, completely surrounds fracture line 3; the rib may be more or less wide, but it starts from a position immediately adjacent the edge 3 of the opening 1b to avoid it breaking or deforming during the dispensing step.
  • the bottom wall F is entirely concave.
  • this concavity is obtained by suitably orienting the wall F to have it converging with side wall L towards the openable lid portion 1b, which is located centrally to the bottom wall.
  • Fig. 1 illustrates the angle of inclination ⁇ of the plane of the bottom wall (P) with respect to the plane (PF) of the bottom wall if this is considered being perpendicular to side wall L.
  • Angle ⁇ generally is within the range of 1 to 15 degrees and preferably of 3 to 10 degrees.
  • a further object of this invention is the use of a capsule as above disclosed, with a dispensing group comprising a puncturing member, wherein the size of said puncturing member portion engaging said capsule bottom wall is greater than the size of said openable portion of said bottom wall.
  • Figures 9-11 show the operation of another embodiment in accordance with the present invention.
  • the dispensing opening is formed by the interaction of the openable outlet lid portion 1b with an opening member 9a located immediately below the capsule, as described in the above mentioned patent application in the name of Societé des Produits Nestlé.
  • Fig. 9 shows this initial position wherein the opening member 9a is adjacent, in contact with or spaced a few millimetres away from outlet lid portion 1 b of the capsule 1.
  • the capsule is pressurized ( fig. 10 ) in a way such as described with reference to the previous figures: hot water fed into the capsule pressurises it and causes the dispensing wall F to bulge outwards and downwards so as to have outlet lid portion 1 b to press against opening member 9a.
  • lid portion 1b is opened along fracture line 3, thus forming an opening 11a through which the beverage flows out.
  • the dispensing wall i.e. the capsule bottom
  • the openable lid portion 1 b moves once again towards the wall F, to a substantially closed opening position ( fig. 11 ) or to a decreased area opening position.
  • the above considerations concerning the decreasing of the opening area from the condition of fig. 10 to that of fig. 11 also apply to this embodiment.
  • figs. 6-8 once sufficient pressure is again built within the capsule, the latter will be once more deformed downwards and the opening area will increase again.
  • the return of portion 1b to the closed position is made easier by the nature of the plastics material used and by providing a hinge 4a which is suitably sized to the purpose.
  • the hinge means is the hinge connecting the outlet lid portion 1 b to bottom wall F.
  • the capsule of the invention can be used for soluble products or for ground products, i.e. ground coffee, tea, herbal remedies, etc.
  • the capsule is provided with filter means and the openable lid portion can open by sheer pressure from inside to outside or, viceversa, by a puncturing element (piston) from outside to inside the capsule.
  • Fig. 12 shows an embodiment of the invention wherein a filter unit consisting of a rigid support 13 and a filter paper 14, known per se in the art, are provided at the bottom of the capsule C.
  • the lateral wall L of capsule C is preferably provided with a circunmferential rib 15 protruding internally and spaced from the bottom so as to provide a means to block into position the filter unit.
  • the openable lid portion 16 of bottom wall F is defined by breaking lines 18 and hinges 17 that can give the outlet lid any suitable shape; e.g. besides the circular shape of outlet lid 1 b above disclosed (shown in phantom lines in fig. 13 ) a square shape ( fig. 13 ) or a cross shape (not shown) can be used.
  • the outlet lid 16 of figures 12-16 has a square shape defined by the H-shaped breaking lines 18 and by hinges 17. In a corresponding cross shaped lid, the fracture lines are arranged in a cross.
  • This outlet lid (as well as all other outlet lids that are provided in a capsule having a filter unit at its bottom) opens towards the outside, as shown by arrows D in fig. 23, once the pressure generated by the hot water pumped into the capsule is high enough to break the lid along breaking lines 18.
  • the two halves of outlet lid 16 will then open in a "window” or “swing-door” way along hinges 17, and will then go back to a closed or almost closed position once the pressure has decreased, to subsequently open again upon a further increase of internal pressure.
  • the filter element is preferably at least slightly spaced from the bottom wall f of the capsule, to provide a volume where the beverage collects before leaving the capsule.
  • the figures 14-16 show a capsule C provided with a filter element having the function of both filtering the ground coffee and of dividing, or partitioning, the internal volume of the capsule.
  • the filter element 13 may have different shapes and dimensions depending on the specific uses which the capsule C is intended to.
  • the filtering/partition element 13 of figure 16 is formed by a spacer 24 having a predefined height extension, in such a way that once inserted in the capsule C, the internal volume of the container left available to the product 23 is reduced to the room between the upper surface of the spacer 24 and the top 22 of capsule C.
  • a paper filter, or another approved material for food, is positioned between the top surface of filter 13 (above spacer 24) and the product 23.
  • Another filter may be interposed between the product 3 and the upper wall of the capsule C.
  • the spacer 24 allows the capsule C to be used both for the preparation of beverages from ground coffee and from soluble products.
  • the capsule C is coupled to the spacer 24 including filter 13
  • the capsule C does not comprise the spacer 24 and the internal volume of the capsule may be completely filled with the product 23.
  • the spacer 24 including filter 13 may be inserted in the capsule when the capsule C is filled with the product 23. If the amount of product 23 is for example not greater than 10 grams, the spacer 24 is inserted in the capsule and works as a double bottom and filter for the capsule C. If the product is soluble, the container 1 does not contain the spacer.
  • the element for dividing the volume of the capsule may be provided also in the traditional capsules, i.e. independently by the means provided for the opening of the capsule.
  • spacer 24 allows to encapsulate product 23 according to the most opportune load and/or the compactness grade.
  • the reduction of the convenient volume of the capsule C may be designed to obtain the desired compactness grade for the product 23 in the capsule C.
