Definitions
- the present invention relates to a pack for preparing a foamed food or beverage product from one or more food or beverage ingredients.
- the invention relates to a pack comprising an insert through and a container where the ingredient or ingredients are stored.
- Preparing beverages by introducing a capsule containing a food or beverage ingredient, such as ground coffee or instant coffee, in a beverage dispensing machine and injecting water into the capsule is known in the state of the art: the beverage or food ingredient is typically extracted or dissolved into water to form the beverage or the desired final product, which flows out of the capsule through a suitable outlet.
- capsules have been developed in the past, these capsules being at least differentiated by the nature of the capsule body used for storing the food or the beverage ingredient. While most of the capsules are made of a rigid body or semi-rigid body, typically made though injection moulding or thermoforming, flexible types of packs can be made out of foil materials. Flexible packs have generally the advantage to semirigid and rigid capsules that less amount of material is used to pack the product which leads to overall less production cost, to lower life cycle impact shown in several life-cycle assessments and to advantages on the part of the user, who will need less available space for storing these packs, as they are more compact.
- a flexible beverage-producing sachet comprising a beverage ingredient in a volume formed by bonding two laminates at their edges, having a base seam into which a conduit of rigid plastics is bonded.
- An inlet nozzle is provided at the top of the resulting sachet for introducing water that is mixed with the beverage or food ingredient inside the inner volume of the sachet, the beverage produced being then evacuated through a beverage outlet arranged at the bottom of the pack, where closing means are provided, such that the closing means are adapted to open under pressure when pressurized water is introduced into the sachet, allowing the beverage to evacuate through the beverage outlet.
- the present invention comes to provide a solution to the above-described need, as it will be further explained.
- the invention also aims at other objects and particularly at the solution of other problems as will appear in the rest of the present description.
- the invention relates to a pack for preparing a food or beverage product from one or more food or beverage ingredients comprising an insert and a container where the ingredient or ingredients are stored: the insert comprises a fluid inlet configured for introducing an aqueous fluid under the form of a jet in the inner volume of the pack, and the insert further comprises an air inlet communicating with the exterior of the pack and configured for introducing air in the inner volume of the pack.
- the air inlet is connected to an aspiration inlet through which the jet enters the inner volume of the pack, configured in such a way that air is aspirated through the air inlet when the jet is introduced inside the pack.
- the air inlet is typically connected to an aspiration inlet through which the jet enters the inner volume of the pack: the air inlet is connectable to external means actively injecting air in the inner volume of the pack.
- the fluid inlet is configured for transforming the pressurized fluid introduced by a beverage machine into a high velocity fluid jet in the inner volume of the pack.
- the fluid inlet communicates with a nozzle having a very restricted diameter with respect to the fluid inlet.
- the pack comprises two flexible water impermeable sheets joined to one another to define the inner volume of the pack.
- the pack of the invention typically comprises a beverage outlet through which the beverage is delivered as a free flow.
- the beverage outlet is preferably a straight tube oriented essentially vertically at the bottom of the pack.
- the insert is preferably arranged on one of the sides of the pack and it comprises the fluid inlet, the air inlet and the beverage outlet.
- the container is configured to open in a certain pre-defined area to allow dispensing of the food or beverage prepared.
- the relative positioning of the aspiration inlet with respect to the air inlet, together with the diameter of the air inlet typically define the level of foaming of the food or beverage prepared.
- the diameter of the nozzle and/or of the aspiration inlet define the design of the jet in the inner volume of the pack.
- the food or beverage ingredient is a soluble food or beverage ingredient.
- the container is configured as a sachet, a capsule or the like.
- the pack of the invention is configured in such a way that the fluid inlet can be accessed frontally and/or by the rear to introduce an aqueous fluid through one or the two sides.
- the air inlet obturation can be typically regulated in order to control the quantity of air injected.
- the pack of the invention typically presents a plane shape oriented along a plane essentially vertically oriented during beverage production and the fluid inlet orientates the jet of fluid in a direction comprised in said plane.
- the invention further relates to the use of a pack as described for preparing a food or beverage product.
- Figs. 1a-b show a pack for preparing foamed food or beverage products according to the present invention.

- 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.
- fluid covers any aqueous diluent that can be mixed with a soluble beverage ingredient to prepare a beverage, like water, carbonated water, milk, etc.
- a soluble beverage ingredient like water, carbonated water, milk, etc.
- water is the preferred fluid which will be used.
- the insert 10 comprises a fluid inlet 1 10 receiving a liquid, typically water, which is injected at a pressure higher than 2 bars, more preferably higher than 3 bars, preferably comprised between 2 and 10 bars, more preferably of around 7 bars.
- the fluid inlet 1 10 is configured in such a way that the high pressure fluid injected through it by external means (not shown) is converted into a high velocity jet 50 in the inner volume of the container 20. This is done thanks to the restriction in diameter of the fluid inlet 1 10, communicating with the inner volume of the container 20 through a nozzle 120 of a much reduced diameter, allowing the transformation of a high pressure jet into a high velocity jet.
- the fluid inlet 110 is communicated with the inside volume of the container through at least one nozzle 120, having a diameter of at most 1 mm, preferably of at least 0.24 mm, preferably comprised between 0.3 mm and 1 mm, preferably between 0.3 and 0.5 mm, more preferably of about 0.4 mm.
- the insert 10 further comprises an air inlet 150 communicating with the exterior of the pack 100 and configured for introducing air in the inner volume of the pack 100 (see for example Figure 5) in order to obtain a good foaming during the dissolution of the powder product comprised inside the container 20.
- the insert 10 is preferably rigid and is made of a rigid plastic material, preferably by injection moulding.
- this plastic material can be selected from the following: polypropylene, polyethylene, polyethylene terephthalate and polylactic acid.
- the fitment assembly 10 can be made of a metal like aluminium or tin-plate.
- the insert of the invention is structurally configured to create an adequate water jet 50 and air into the volume of the container in order to control and stabilize foaming of the product beverage produced.
- the product inside the container is a soluble powder that will be dissolved by the water jet 50.
- air will be introduced inside the volume of the pack through the air inlet 150, a proper foaming of the product will be also achieved.
- the pack of the invention can be configured as a sachet, for example, by flexible films or sheets folded to conform a container 20.
- Other configurations are also possible, for example configuring the container as a capsule, as a pod or the like.
- the insert 10 will be a part comprising the fluid inlet 1 10, though other configurations are also possible where the fluid inlet 1 10 is for example directly made by piercing the material configuring the walls of the container 20 (being the container a pouch, a capsule, a pod, or the like).
- the pack 100 of the invention will comprise two flexible water impermeable sheets joined to one another to define the inner volume of the pack or of the container 20, where the product (typically powder) is stored and is further processed with the water jet 50 to prepare the beverage dispensed.
- the pack further comprises a beverage outlet 160 through which the beverage is delivered as a free flow.
- the beverage outlet 160 in the pack 100 there are several possibilities of providing the beverage outlet 160 in the pack 100, one of them being a straight tube oriented essentially vertically at the bottom of the pack, provided in the insert 10, as represented in Figure 2.
- outlet 160 is not arranged in the insert 10 (see Figure 3) but directly in the container 20, configured to open in a certain pre-defined area to allow dispensing of the food or beverage prepared (typically, when the container 20 is made by flexible sheet or sheets configuring an inner volume, the sheet(s) will be able to separate from each other under a certain pressure for example, allowing the exit (dispensing) of the beverage inside.
- the insert 10 is arranged on one of the sides of the pack 100, and it comprises the fluid inlet 1 10 and the air inlet 150. It will preferably also comprise the beverage outlet 160.
- a pack 100 according to a possible embodiment of the invention is disclosed.
- the pack is configured comprising an insert 10 and a container 20, essentially defining a vertical plane P, the insert 10 being arranged at the lower side of the pack.
- the container 20 will comprise inside its volume a product, typically a powder, more specifically a concentrated powder, from which, by adding a liquid (typically water) through the insert 10, as a jet of liquid, the powder will be dissolved, mixed and homogenized into a beverage.
- a product typically a powder, more specifically a concentrated powder
- the beverage prepared will be dispensed either through an outlet 160, configured as a vertical tube as shown in Figure 2, or through other outlet means, arranged somewhere else in the pack or for example, as previously explained, though an opening made by separation of the sheets configuring the container 20, this separation happening under certain controlled pressure conditions; in any of these cases, the insert 10 will not comprise the beverage outlet, as represented in Figure 3.
- Figure 4 shows a detail of the insert 10 arranged in a pack 100 according to the present invention, also showing a fluid inlet 1 10 through where a fluid (typically water) will be introduced inside the pack.
- the insert 10 will be further configured in such a way that it will be able to be accessed frontally and also from the rear side, meaning that the consumer will not have to care on the way how the pack is placed in the machine, as it will be able to be accessed on both sides, i.e., the pack is made reversible.
- the fluid inlet 110 is made on the two sides (frontal and rear) of the insert 10: in fact, it comprises a substantially horizontal tube going through the transversal section of the insert 10, from one of its sides to the other, allowing it to be accessible through its two ends.
- the injecting means (not shown) will be configured also as piercing means, able to pierce the sheet over the fluid inlet 1 10 and after this to inject the fluid.
- the injection means will be arranged in a particular location in the beverage preparation machine so as to pierce and access the fluid inlet 1 10, independently if the pack is positioned on one of its two sides, as long as it is placed substantially vertically along a plane P.
- the flexible sheet or sheets configuring the container 20 also overwrap fully the insert 10, except for the part of it being inside and in communication with the inner volume of the container 20. More preferably, there is one flexible sheet arranged overwrapping the whole insert 10, configuring the inner volume of the container 20 by sealing its ends.
- the injecting and piercing means are preferably a fluid needle, called in what follows needle, such that these injecting and piercing means typically comprise an inner duct or pipe through which high pressure fluid is injected in the fluid inlet 1 10.
- a pressurized fluid is introduced through a fluid inlet 1 10 in the insert 10 arranged at the lower side of the pack 100.
- the pressurized fluid is forced to go through a nozzle 120, having a much reduced diameter with respect to the section of the fluid inlet 1 10, which makes that the fluid losses its pressure in favor of speed and so a jet of fluid 50 is created into the inner volume of the container 20.
- the jet of fluid 50 goes into the inner volume of the container 20 through an aspiration inlet 130, which is also communicated to the outside of the pack with an air inlet 150.
- the air inlet 150 is connected to an aspiration inlet 130 through which the jet 50 enters the inner volume of the pack 100, configured in such a way that air is aspirated through this air inlet 150 when the jet 50 is introduced inside the pack, by the speed of the jet coming into the inner volume of the pack.
- the air inlet 150 is connected to external means actively injecting air in the inner volume of the pack 100, for example an air pump or the like.
- the two possible configurations would be passive air aspiration (by opening the air inlet 150 to the outside so that air is aspirated while the fluid jet 50 enters the inner volume of the container 20) or active air injection by actively injecting air through the inlet 150 when an active air pump is connected to this air inlet 150.
- the air inlet 150 obturation can be regulated in order to control de quantity of air injected through the inlet 150, typically from no (closing the air inlet 150) to certain foaming (regulating the entrance of air and the opening of the air inlet 150) up to active air pumping (maximum foaming).
- Figure 5 also shows dimensions of the insert 10, of its elements and their positioning within the insert and also with respect to the pack 100, influencing the characteristics of the final beverage obtained. These dimensions are typically:
- Diameter Di it is the diameter of the fluid jet 50
- Diameter D 2 it is the diameter of the air inlet 150
- Diameter D 3 it is the diameter of the aspiration inlet 130
- Li it is the relative positioning of the air inlet 150 with respect to the fluid jet 50 and to the aspiration inlet 130
- L 2 it is the height of the aspiration inlet 130, measured with respect to the air inlet 150
- the relative positioning of the aspiration inlet 130 with respect to the air inlet 150 (dimensions Li , L 2 ), together with the diameter of the air inlet 150 (D 2 ), define the level of foaming of the food or beverage prepared.
- the diameter of the nozzle 120 (same as the diameter of the jet 50, dimension Di ) and/or of the aspiration inlet 130 (diameter D3) define the design of the jet 50 in the inner volume of the pack.
- the fluid inlet 1 10 can be configured for providing an orientable high velocity jet into the container 20, preferably at about 90° with respect to the fluid supply provided into the fluid inlet by the injecting and piercing means, though any other angle would be possible and comprised within the scope of the present application.
