Definitions

  • the present invention relates to a system for dispensing individual portions of liquid food or beverage in collapsible containers, such as pouches.
  • the invention further relates to methods of operation of such a system, and to pouches for use in such a system.
  • US-A-5731021 describes a collapsible canteen formed by a collapsible carton having nested therein a collapsible pouch whose open mouth is in alignment with a neck projecting from the carton.
  • the collapsible canteen has a charge of powdered beverage concentrate deposited in the pouch.
  • hot or cold liquid is poured through the neck of the canteen into the pouch to dissolve the powder and prepare the beverage.
  • the neck on the carton is provided with a screw thread, and a complementary threaded cap can be secured on the neck.
  • US-A-5850939 describes a squeeze canteen for producing and dispensing a soft drink.
  • the canteen includes a collapsible pouch moulded to simulate a known character and provided with a socket forming the mouth of the pouch. Inserted in the socket is a removable drinking nozzle. Deposited in the pouch is a charge of water-soluble flavour capsules.
  • the pouch is filled with water through the socket, and the nozzle is then inserted into the socket. It is apparent that the steps of filling the pouch and inserting the nozzle in liquid-tight fashion will be problematical.
  • a need therefore exists for improved packaging formats for distribution and consumption of liquid foods and beverages and that overcome one or more of the above-identified disadvantages.
  • the present invention provides a dispensing system comprising: a partially or completely collapsed container for containing an individual portion of a liquid food or beverage, wherein the container comprises an inlet and a seal that substantially seals the inlet; and a liquid dispensing mechanism adapted to release the seal on the inlet and to inject a liquid into the container through the inlet.
  • the container is initially in a collapsed, sealed state containing little or no liquid. It may contain a concentrated food or beverage ingredient, as discussed further below.
  • the concentrated ingredient is inherently storage stable due to its low water activity.
  • the container can be stored and distributed in this compact, lightweight condition.
  • the liquid dispensing mechanism can then be used immediately or shortly before consumption to inject water or another liquid into the container to produce a portion of the liquid food or beverage stored inside the container.
  • the collapsible containers in the systems according to the present invention both store the ingredient before the liquid injection step and store the product portion after liquid injection.
  • the invention permits the extemporaneous preparation of a wide range of novel liquid food and beverage products that are not sufficiently stable for storage and distribution in packs.
  • the collapsible container in the systems according to the present invention comprises a container body, and inlet, and optionally an outlet separate from the inlet.
  • the container body is preferably collapsible to a substantially flat state when empty. It may for example be a collapsible carton made up of panels joined by fold lines. However, most suitably the collapsible container body is a flexible pouch.
  • the term "flexible pouch" refers to a closed container formed substantially or completely of a flexible sheet material.
  • the sheet material normally comprises at least one continuous layer of a thermoplastic, or it may be a laminated sheet made up of more than one thermoplastic film layer. At least a portion of the sheet material may be transparent to allow inspection of the pouch contents.
  • the sheet material is substantially impermeable to liquids, and it may also be substantially impermeable to gases such as oxygen, especially when it is desired to maintain the freshness of the pouch contents.
  • the sheet material making up the pouch may further comprise a metal layer, such as an aluminium layer, to render the material air-and light- impermeable and to provide aesthetic effects.
  • the material used to make the container body may be heat-resistant and optionally also thermally insulating, for example where the product being made inside the container is a hot beverage by injection of hot water into the container.
  • the collapsible container body may comprise a layer of sheet material containing entrapped gases such as entrapped air or CO 2 to provide thermal insulation. This may conveniently be achieved by including a layer of foamed polymeric material in the sheet material. Thermal insulation of the sheet material may additionally or alternatively be accomplished by incorporating a layer of fibrous material, for example a textile material or a non-woven fibrous material such as a spunbonded web or a wet-laid fibrous web.
  • the collapsible container body may comprise a pouch enclosed in a collapsible carton, for example as described in US-A-5731021.
  • the collapsible container body may comprise both flexible sheets and panels joined along fold lines.
  • the body of the collapsible container preferably is preferably a pouch that consists essentially of the flexible sheet material.
  • the pouch may, for example, be a so-called pillow pouch, typically formed by continuous form-fill-seal equipment, or it may be formed by bonding together front and back faces of flexible sheet materials around their marginal edges.
  • the pouch may be a stand-up pouch. That is to say, a pouch formed by bonding together front and back faces of sheet material around three edges, with a gusset sheet inserted and bonded to the respective fourth edges of the front and back sheets to form a base for the pouch.
  • the total thickness of each flexible wall of the pouch is suitably in the range of from 50 micrometers to 1000 micrometers, for example 100 micrometers to 500 micrometers.
  • the collapsible container may be provided with a nip and/or a line of weakness and/or a tear strip to allow the container to be opened after filling.
  • the internal volume of the collapsible container when folly expanded is sufficient to store the liquid food product portion being made in the container.
  • the volume of the container defined as the maximum volume of water that can be filled into the container (for example by gravity feeding from a height of 10cm above the inlet) is suitably from 50 ml to 1000 ml, preferably from 100 ml to 500 ml, for example from 150 ml to 350 ml. This volume is appropriate for containing an individual portion of a food or beverage liquid, that is to say a portion suitable for consumption by one human individual at one time.
  • the containers are partially or completely collapsed before liquid injection.
  • the containers are substantially free from entrapped gas before the injection step; that is to say, the containers contain substantially only the the food or beverage ingredients, with substantially no gas or headspace. This minimises the volume of the containers for storage and distribution purposes, and maximises the stability of the pouch contents.
  • the flexible pouches may be folded, or rolled, up before the liquid injection step.
  • the containers may be substantially empty before the liquid injection step.
  • Such containers would be suitable for receiving water, for example chilled water and/or filtered water for immediate consumption.
  • Such containers would also be suitable for receiving flavoured beverages from a flavoured beverage mixer/dispenser.
  • the collapsible containers contain a beverage ingredient, for example a concentrated or dried beverage ingredient, such as flavored sugar syrups, soluble coffee solids or soluble tea solids.
  • the collapsible containers contain a low moisture food ingredient, for example a breakfast cereal.
  • the total weight of the food or beverage concentrate in the containers before water injection is from about 0.5 grams to about 100 grams, preferably from about 1 gram to 50 grams.
  • the containers may comprise more than one compartment.
  • two or more of the compartments are adapted to permit mixing of the compartment contents after injection of liquid into the collapsible container.
  • a food or beverage ingredient may be present in one or more of the compartments.
  • the compartments may, for example, be separated by a line of sealing between the front and back faces of a pouch. In certain embodiments this line of sealing is releasable by the action of heat or pressure (e.g. from squeezing a pouch), whereby mixing of the compartment contents can be achieved after filling of the pouch. This mixing can be applied to achieve novel colour, flavour, temperature and/or texture effects in the product.
  • Suitable multicompartment pouches and laminated film materials for the manufacture of such pouches are described, for example, in WO2004/058594, the entire content of which is incorporated herein by reference.
  • the containers in the dispensing system according to the present invention further comprise an inlet, and a seal that substantially seals the inlet against the ingress or egress of liquid or oxygen etc. until the liquid injection step.
  • the inlet comprises a substantially rigid nozzle (or spout) that is bonded into the containers.
  • the nozzle may extend through a hole in the container wall, and may further comprise a flanged base bonded in liquid-tight fashion to the sheet material of the container wall on the inside of the pouch.
  • the nozzle may be inserted in liquid-tight fashion between opposed sheets of material in an edge of the container, for example as in the well known beverage brewing sachets described in GB-A-2123685 and the related applications listed herein.
  • the nozzle it is not necessary for the nozzle to have a flange inside the pouch, since the front and back faces of sheet material wrap around the sides of the nozzle in liquid-tight fashion.
  • the nozzle is typically formed from molded thermoplastic, for example by injection molding.
  • the nozzle has an opening therein for passage of liquids, for example the opening may be a tubular bore.
  • the opening is initially sealed by the seal.
  • the seal may, for example, comprise a membrane extending across the opening that is pierced by an injector on the liquid dispensing mechanism.
  • the membrane may be an elastomeric septum or split septum that provides at least a degree of sealing after the injector has been withdrawn.
  • the seal does not comprise any frangible part that could be pushed into the pouch by the injector and thereby contaminate the contents.
  • the seal could be provided by a mechanical valve arrangement, for example a biased valve such as a spring-loaded valve that is released by the action of the liquid dispensing mechanism.
  • Alternative valve arrangements include any of the well known sports cap valves formed from two or more thermoplastic parts, wherein the valve is opened by twisting or pulling on an outer valve part.
  • the nozzle preferably projects outwardly from the container by at least about 5mm, and may be provided with a locking recess or projection, to enable the nozzle to be gripped by the liquid dispensing mechanism during liquid injection.
  • Suitable locking recesses or projections include a flange, a thread, a socket or a bayonet fitting.
  • the containers in the dispensing system according to the present invention preferably further comprise a valve element that resists the escape of liquid from the liquid-filled container through the inlet after the liquid has been injected into the container.
  • a valve element that resists the escape of liquid from the liquid-filled container through the inlet after the liquid has been injected into the container.
  • the valve element allows liquid to escape through the inlet when a pressure difference is applied across the valve, for example by squeezing the container or applying suction to the inlet.
  • the valve element substantially completely blocks the escape of liquid from the liquid-filled container. This is the case, for example, when a valve element is provided by a bias e.g. spring loaded valve in the inlet.
  • Such sealing arrangements are especially convenient when a container is further provided with a separate outlet opening, as described further below.
  • the liquid dispensing mechanism may further comprise a device for sealing the inlet after liquid injection step is complete.
  • the sealing device may, for example, comprise a threaded neck on the inlet for attachment of a complementary threaded cap over the inlet.
  • the sealing device may comprise a cap or a plug seal for forming an interference fit or a snap-fit on the inlet, wherein the plug or cap is attached to the inlet nozzle, for example by a hinge, for example the plug or cap and the hinge may be molded in one piece with the inlet nozzle.
  • a particularly preferred valve element is a split septum or X-cut septum, or a septum having lines of weakness that are split by the action of the injector.
  • these valve elements have the advantage that a drinking straw can be inserted through the septum for consumption of the container contents after filling.
  • the containers in the dispensing systems according to the present invention may further comprise a drinking straw attached to the outside of the container.

  • the coffee brewing sachet is substantially identical to the commercially available FLAVIA coffee brewing portion packs of the kind described in GB-A-2123685, GB-A-2123685, GB-A-2121762 and GB- A-2122881.
  • the sachet comprises rectangular front and back faces 40,42 of flexible sheet material in face-to-face relation.
  • the faces 40,42 and bonded together around the edges thereof to form a rectangular sachet.
  • the bottom edge 44 of the sachet is bonded with a heat- and pressure-sensitive adhesive, whereby the front and back faces 40,42 peel apart along the bottom margin 44 when hot water is injected into the sachet.
  • the top edge of the sachet 38 is overlapped by, and bonded to the top edges of the front and back faces 32,34 of the main container body.
  • the sachet 38 contains ground coffee 46 and a filter paper barrier 48 bonded to the internal surfaces of the front and back faces 40,42 to retain the ground coffee in the sachet.
  • An inlet nozzle 50 is inserted in the top edge of the collapsible container. It is sealed in liquid-tight fashion between the front and back faces 40,42 of the sachet 38, whereby liquid injected into the inlet nozzle 50 passes directly into the sachet 38, and not into the main container body 31.
  • the nozzle has a tubular bore, and a flange 52 at the distal end of the bore.
  • the beverage dispensing machine suitably comprises a clamp that grips the inlet nozzle bore underneath the flange 52.
  • a frangible freshness barrier such as a membrane seal, is provided in the nozzle inlet to maintain freshness of the sachet contents before use.
  • the coffee 46 is sealed inside the sachet 38 before use. This means that only the sachet 38 needs to be made of relatively expensive high-barrier laminate.
  • the properties of the main container body sheet material can be independently optimised for cost and other desirable parameters. It is a further advantage of this embodiment that the sachets 38 can be made on existing machinery prior to insertion into the main collapsible container body.
  • An outlet tube 58 is provided on one of the flexible faces 34 of the main container body 31.
  • the outlet tube 58 is inserted into a hole in the flexible sheet 34, and a flange 60 on the outlet tube is bonded in liquid-tight fashion to the inside of the flexible sheet 34 around the hole.
  • the outer end of the outlet tube 58 is threaded, and a threaded cap 62 seals the outlet tube.
  • hot water typically at about 9O 0 C and 0.2-0.5bar gauge pressure is injected into the inlet nozzle 50 through an injector tube that also serves to pierce the freshness barrier.
  • the hot water infuses the coffee 46 in the sachet 38, and the heat and pressure of the water act to release the seal in the bottom edge of the sachet as shown in Fig. 5, thereby releasing the coffee liquid 54 into the main container body 31, where it is retained.
  • a final pulse of air is pumped into the inlet nozzle 50 through the injector tube to dewater the coffee grounds 46 and to provide a headspace 56 in the pouch.
  • the coffee can then be poured or sipped through outlet 58.
