Definitions

  • the present invention relates to packs and machines for the preparation of foods or beverages from packs comprising a food or beverage ingredient.
  • Different capsules have been developed in the past that can differentiate at least by the nature of the capsule body used for storing the food or beverage ingredient. Whereas most of the capsules are made of a rigid body or semi-rigid body (e.g. made though injection moulding, thermoforming, deep drawing, . . . ) flexible types of packs or sachets can be made out of foil materials. Flexible packs have generally the advantage to semi-rigid and rigid capsules that less amount of material is used to pack the product which leads to overall less production cost and lower life cycle impact shown in several life-cycle assessments.
  • WO 99/05044, GB 2 374 856 and WO 2012/175985 describe such a flexible pack made of two sheets of flexible air- and liquid-impermeable material bonded on theirs edges to define an inner volume for storing the beverage ingredient.
  • the pack comprises an inlet nozzle at its top for introducing water that is mixed with the beverage ingredient inside the inner volume.
  • the beverage is evacuated through a beverage outlet at the bottom of the sachet.
  • the outlet is created further to bursting of the pack under the pressure of water introduced in the sachet.
  • the outlet is created due to the separation of the bottom edges of the flexible sheets further to the effect of heat or pressure in the sachet.
  • a spout can be introduced at the bottom of the pack: in that embodiment, the bottom edges of the flexible sheets do not separate and the beverage is evacuated by the spout.
  • the opening of the beverage outlet is obtained by increase of pressure inside the sachet. Yet this pressure increase is not recommended for the preparation of some beverages because it creates bubbles at the surface of the beverage; for example it is not desired for the preparation of tea. Besides there can be a risk that the packages may not rupture at the desired pressure and that it can finally opens up in an uncontrollable explosion. For this reason the apparatus comprises means for totally enclosing the pack in the machine during beverage preparation and avoid damages or injuries for the operator.
  • WO 2011/024103 describes a pack for preparing a beverage defining an inner volume for storing the beverage ingredient.
  • the inner volume is closed at its top by a rigid piece that integrates the water inlet and the beverage outlet.
  • Such a pack only enables the preparation of flat beverages obtained by the circulation of water through a food ingredient like roast and ground coffee without pressure. No multi-components beverage can be produced from such a pack.
  • WO 2011/054402 describes a capsule with an interior space comprising a first beverage ingredient and a floating insert, said floating insert comprising a second beverage ingredient. Dual-layered beverages can be obtained by introducing water in the interior space to produce a first component of the beverage and then destroying the floating insert to produce a second component of the beverage.
  • a capsule is complex in terms of manufacturing. During the beverage preparation the capsule is horizontally oriented and consequently beverage is not freely evacuated from the interior space: for this reason the machine comprises a piston to empty the capsule.
  • the present invention aims to propose a range of flexible packs that can be used for preparing different types beverages from at least two different beverage components, said components being separately stored in the packs.
  • the invention concerns a pack with an inner volume in which at least two different food or beverage ingredients are stored and in which a beverage is produced when water is introduced inside,
  • said inner volume being defined by sheets of material joined to one another at their edges and said inner volume presenting a generally plane shape defining a plane (P) vertically oriented during beverage production, said pack comprising at least one inlet for introducing water in the inner volume and at least one outlet for delivering the beverage from said inner volume, said water inlet and said beverage outlet being positioned at the bottom of the pack and being at least partially positioned between two joined edges of the sheets of material, and wherein the inner volume includes a plurality of compartments, the compartments being separated by at least one releasable or separable bond, and wherein the water inlet and the water outlet are positioned between two joined edges of the sheets of material so that they both establish fluid communication within the same compartment.
  • the pack comprises two sheets joined to one another to define the inner volume.
  • the sheets are preferably flexible water impermeable sheets. Consequently the pack itself is substantially flexible.
  • flexible it is meant that the sheets can be bent easily.
  • the resulting pack can be bent also; it is soft and can be deformed contrary to rigid containers.
  • the flexible sheet material can be plastic laminates, metallised foil or alufoil or fibre base material.
  • the two sheets can be formed of one single sheet folded in half and joined at its free edges.
  • the pack presents a generally plane shape that is essentially vertically oriented during beverage production.
  • the pack can comprise more than two sheets, in particular to increase the size of the inner volume.
  • Other sheets can be joined to the two first sheets that defining the inner volume and the generally plane shape according to plane (P); said other sheets creates a doypack shape for the inner volume.
  • the water inlet and the beverage outlet are at least partially positioned between two joined edges of the two first sheets of material that define the generally plane shape (P) of the pack.
  • the beverage outlet is preferably configured so that it delivers the beverage as a free flow once it is opened.
  • the beverage can flow from the outlet by simple gravity fall.
  • the tube creates a communication between the inner volume and outside.
  • the pack comprises at least one inlet for introducing water in the inner volume and at least one outlet for delivering the beverage from said inner volume, said water inlet and said beverage outlet being positioned at the bottom of the pack and being at least partially positioned between two joined edges of the sheets of material, the external end of the water inlet being oriented essentially perpendicularly to the plane (P) defined by the inner volume, whereas the beverage outlet is a tube extending essentially vertically from the inner volume.
  • the water inlet and the beverage outlet are essentially perpendicularly oriented one to the other. Consequently the inlet and the outlet emerge on different sides of the pack.
  • This configuration limits the contamination risk of the means for introducing water in the water inlet by the beverage dispensed by the beverage outlet.
  • the inlet and the outlet can be made in one single insert or can be two separate inserts separately positioned in the pack.
  • the insert(s) is(are) preferably rigid.
  • the inserts are made of a rigid plastic material.
  • This plastic material can be selected in the list of: polypropylene, polyethylene, polyethylene terephthalate and polylactic acid.
  • the insert can be made out of a metal like aluminium or tin-plate.
  • the insert(s) can be injection molded.
  • the insert comprising the water inlet is positioned in joined bottom edges of the sheets of material so that the water inlet is closed by one sheet of material defining the inner volume.
  • the water inlet insert can be positioned in joined bottom edges so that the water inlet is not closed by one sheet of material defining the inner volume. In that case the water inlet insert is only partially positioned between two joined edges of the sheets of material.
  • the insert comprising the beverage outlet is positioned in joined bottom edges of the sheets of material so that the external end of the beverage outlet is positioned under the joined bottom edges of the sheets of material.
  • the beverage outlet is not covered by the sheet. Yet it can be visually hidden by a part of the sheet e.g. by a skirt of the sheet.
  • the pack comprises one single insert including the water inlet and the beverage outlet, said single insert being positioned at the bottom of the pack and being partially positioned between two joined edges of the sheets of material.
  • the single insert is positioned in joined bottom edges so that the water inlet is closed by one sheet of material defining the inner volume.
  • the external end of the beverage outlet is positioned under the joined bottom edges of the sheets of material.
  • the single insert can be positioned in joined bottom edges so that the water inlet is not closed by one sheet of material defining the inner volume. In that case the insert is only partially positioned between two joined edges of the sheets of material.
  • the single insert is positioned at or next to the middle of the bottom of the pack. It can also be positioned in the corner of the pack when the latter presents a corner.
  • the water inlet and the beverage outlet of the pack are both simultaneously included in said same single insert.
  • This feature covers the fact that the water inlet and the beverage outlet are part of the same insert piece in the pack.
  • this insert can be produced by the association of several parts before the complete piece is used for manufacturing the pack. In particular different parts can be attached, e.g. clipped, together to form the final single insert before said single insert is used for manufacturing the pack.
  • the single insert of the pack presents a shape for cooperating with the pack receiving area of a beverage production machine.
  • it can present a shape configured for sliding in the slot of the receiving area of a beverage production machine like an iron shape.
  • the pack can be made of only one flexible material sheet, said sheet being folded at the top of the pack and bonded on its edges to define the inner volume, the bottom joined edge including the insert.
  • This embodiment constitutes a particularly easy way to manufacture the pack since it requires the cutting of only one piece of sheet—most preferably according to a rectangular shape—and its folding to create the inner volume for the food or beverage ingredient.
  • the insert(s) can be introduced in the bottom edge during the sealing of the edges.
  • the pack can be made of two flexible material sheets, said sheets being bonded on their edges to define the inner volume, the bottom joined edges including the insert.
  • the insert(s) can be introduced in the bottom edges during the sealing of these edges, two other side edges of the pack can be bonded so that the inner volume is defined and beverage ingredient can be introduced in said inner volume. Finally the last edges can be bonded to close the inner volume.
  • the insert(s) can be positioned at any place at the bottom of the pack between the both lateral sides of the bottom; it (they) can be positioned at a bottom lateral side in particular a corner if the pack is globally rectangular or at any place between the corners.
  • the food or beverage ingredient of the pack can be comprised within the list of: soups, fruit juices, vegetable juices, bouillons, coffee, chocolate, tea, milk or creamer, smoothies, purees, coulis, creams or a combination thereof.
  • the food or beverage ingredient can be a soluble food or beverage ingredient.
  • the food or beverage ingredient is a soluble food or beverage ingredient selected in the list of:
  • the powders can be agglomerated or sintered.
  • the powders or liquid concentrates can be mixed with solid pieces for example for preparing soups with solid pieces.
  • the food or beverage ingredient can also be an infusable food or beverage ingredient like a roast and ground coffee or tea leaves. In that embodiment water extracts the infusable ingredient.
  • the insert including the water inlet is enclosed in the pack by the sheet(s) of material that defines the inner volume of the pack.
  • the water inlet can be positioned in the pack so that it is almost totally essentially vertically oriented during beverage production.
  • the external end of the water inlet represents the end of the water inlet channel that cooperates with a water supply at the outside of the pack whereas the internal end of the water inlet represents the end of the water inlet channel that delivers water inside the pack.
  • the external end of the water inlet is oriented essentially perpendicularly to the plane (P) defined by the inner volume. Accordingly the water inlet is at least partially essentially horizontally oriented during beverage production.
  • the external end of the water inlet is preferably covered by said sheet of material. Consequently the same piece of material can be used to simultaneously create the inner volume of the pack, close the water inlet and protect the external end of the water end. Due to the enclosure of the beverage inlet in the pack there is no need for a particular membrane for closing the water inlet.
  • the invention provides a pack that is easy to manufacture and guarantees hygienic and shelf life protection of the food and beverage ingredient and the produced beverage.
  • the single insert presents ribs on its external surface for improving the adhesion with the flexible material sheet during sealing.
  • a raising edge can surround the water inlet so as to improve air and water tightness around it.
  • the insert is configured so that the longitudinal axis of the water inlet channel at its internal end is almost comprised in the vertically oriented plane P.
  • the water inlet can be configured so that the direction of the water flow in the external end of the water inlet is almost perpendicular to the direction of the water flow in the internal end of the water inlet.
  • the internal design of the water inlet enables a globally perpendicular change of orientation of the water flow from the external end of the water inlet (that faces the external part of the pack) to the internal end of the water inlet (that faces the internal part of the pack).
  • the external end of the water inlet can comprise an inlet chamber which comprises an evacuation end, said evacuation end being an injection hole configured for directing water in the inner volume of the pack in a direction almost perpendicular to the inlet chamber longitudinal axis.
  • the inlet chamber is globally horizontally oriented.
  • This chamber is usually configured for receiving a hollow needle for injecting water. It generally presents a circular section.
  • This chamber presents the advantage of creating a distance between the end of the hollow needle and the inner volume which stores the beverage ingredient and consequently avoids the contamination of the needle.
  • the chamber evacuation end is a hole pierced in the lateral wall of the chamber.
  • the water inlet is configured for introducing water under the form of a jet in the inner volume of the pack.
  • jet it is understood a stream of liquid that comes out of the water inlet and in the inner volume of the pack quickly and with force.
  • the water inlet is configured for introducing water in the inner volume of the pack with a high velocity.
  • the water inlet is configured for introducing a water jet in the inner volume of the pack, said water jet presenting a velocity of at least about 20 m/s, preferably at least 30 m/s.
  • the water inlet is configured for transforming the pressurized water introduced by a beverage machine in the pack in a high velocity water jet in the inner volume of the pack.
  • Such a configuration can be obtained by placing a constriction in the water path in the water inlet to reduce the size of the section of the water inlet. Due to the small surface of the inlet section pressurized creates a jet of water in the inner volume.
  • the water inlet comprises a hole presenting a transverse section with a surface area equivalent to the surface of a circular surface of diameter of at most 1 mm, preferably at least 0.24 mm.
  • the velocity for water emerging from the injection hole usually depends from the pressure of the water introduce at the water inlet.
  • the invention generally applies for water pressurised between 2 and 10 bar, preferably of about 7 bar.
  • the water inlet generally comprises an injection hole presenting a transverse section with a surface area equivalent to the surface of a circular surface of diameter comprised between 0.2 and 0.8 mm, preferably between 0.3 and 0.5 mm and even more preferably of about 0.4 mm.
  • the water inlet preferably comprises an injection hole presenting a transverse section with a surface area equivalent to the surface of a circular surface of diameter comprised between 0.5 and 1.5 mm, preferably of about 1 mm.
  • the small surface of the injection hole presents the advantage of avoiding any back flow of liquid contained in the inner volume of the pack through the water inlet.
  • the surface of the diluent injection hole can vary according to the nature of the food and beverage ingredient inside the pack. In particular when the ingredient is difficult to dissolve a smaller injection hole creates a jet with a higher velocity which improves agitation and dissolution in the pack.
  • the pack presents a plane shape oriented along a plane essentially vertically oriented during beverage production and the water inlet orientates the jet of water in a direction comprised in said plane.
  • the water jet introduced from the bottom into the pack is developing into circular and/or spiral movements creating turbulences, frictions and high contact surfaces between the water molecules and the product particles. In average the water molecules have several turns within the sachet until they leave the sachet with the beverage.
  • Packs with single insert placed in the corner of an essentially rectangular pack also improve reconstitution.
  • This particular embodiment with creation of a jet is particularly interesting for packs comprising soluble beverage ingredients.
  • the creation of a water jet in the pack is not desirable, for example for packs comprising infusable ingredients. Consequently the size of the water injection hole can be configured to avoid a jet in the inner volume of the pack.
  • the beverage outlet is closed at its end.
  • the beverage outlet is closed by manufacturing and is configured for being opened at beverage production step.
  • closed by manufacturing it is meant that the pack is manufactured with a closed beverage outlet. This closure guarantees hygienic and shelf life protection.

  • the plug is part the single insert comprising the beverage outlet and the water inlet.
  • the beverage outlet is a pipe and the connection between said pipe and the plug presents a mechanical weakness.
  • This mechanical weakness can be a narrowing so that it can be made easy to cut or tear off the plug with a beverage outlet opening device of a beverage preparation machine.
  • This reduced transversal section of the connection between the plug and the beverage outlet pipe creates a weakness.
  • the plug can be pulled according to a downwardly oriented direction or a laterally oriented direction or a combination of these both directions.
  • connection between the pipe and the plug presents a smaller section than the plug upper surface and preferably smaller than the pipe section.
  • the plug upper surface is larger than the connection section, it provides a surface to have a hold to tear the plug or to anchor a pulling device, for example to anchor a tearing device like the teeth of a fork.
