  • Such a length generally enables a finalisation of the froth of the product, typically a beverage, before it is delivered in a drinking cup.
  • An advantage of using such a dispensing fluid outlet 23 is that there is no need to implement a particular connection between the outlet and the machine or device when a food or beverage product is produced in order to direct the flow of the product delivered: the food or beverage product can flow from the dispensing fluid outlet 23 directly into a drinking cup or appropriate recipient.
  • the dispensing fluid outlet 23 is closed at its end.

Also according to a less preferred embodiment the fitment assembly 20 can be made of a metal like aluminium or tin-plate.
  • the fluid inlets 21 , 22 are piercable by injecting means, typically piercing and injecting means, preferably a fluid needle, called in what follows needle, such that these injecting means typically comprise an inner duct or pipe through which fluid (typically water) is injected in the fluid inlets 21 , 22 at a certain pressure, which can be higher than atmospheric pressure, typically higher than 1 bar or higher than 2 bar.
  • the fluid inlets 21 , 22 are configured for introducing the fluid in the form of a jet in the inner volume of the container or containers: in fact, the fluid inlets are configured for transforming the fluid (typically pressurized) introduced in the pack by the piercing and injecting means of the device 40 into a fluid jet circulating inside the volume of the pack.
  • Such a configuration is preferably obtained in the present invention by placing a constriction (that of the injection hole) in the fluid path in the fluid inlet to reduce the size of the section of the fluid inlet. Due to the small surface of the injection hole through which the fluid goes into the inner volume of the pack, the pressurized fluid creates a jet in the inner volume of the container or containers.
  • a fluid jet is to be understood as a stream of fluid projected into the inner volume of the pack typically from a nozzle, orifice or constriction.
  • the fluid jet is conveyed into the inner volume of the pack through the constriction (that of the injection hole) and a circulation of the fluid is established inside this volume and typically around the frozen ingredient arranged inside.
  • the fluid jet is provided with a higher momentum compared to the surrounding medium inside the pack, the momentum being given by the product of the fluid mass and its velocity.
  • the important feature is that the fluid injected into the inner volume of the pack circulates inside this volume allowing the melting of the majority of the frozen or partially frozen ingredients kept inside.
  • these fluid inlets 21 , 22 are directly accessible by injecting means which will inject fluid directly without the need to pierce any external lid or membrane in these fluid inlets.

  • the injecting means also comprise a toroidal ring, preferably made of rubber, ensuring that there is no leakage of fluid outside the fluid inlet while the injecting means are injecting fluid into the fluid inlet.
  • Each fluid inlet is communicated with the inside volume of the container 30 through an injection hole 26 which can be different for each fluid inlet or which can be common for both fluid inlets.
  • the fluid inlets can also be configured for providing an orientable jet into the container, preferably at about 90° with respect to the fluid supply provided into the fluid inlets by the injecting means, though any other angle would be possible and comprised within the scope of the present application.
  • the fluid inlet or inlets are configured for introducing a fluid jet in the inner volume of the pack under a certain pressure with a velocity (thus, having a certain momentum) that allows the circulation of the fluid inside the volume of the container or containers, more specifically creating a circulation around the frozen or partially frozen ingredient kept inside: in this way, better melting of the most part of the ingredients is achieved.
  • a configuration is preferably obtained by placing a constriction (that of the injection hole) in the fluid path in the fluid inlet to reduce the size of the section of the fluid inlet. Due to the small surface of the injection hole through which the fluid goes into the inner volume of the container, the fluid creates a circulating flow in the inner volume of the pack.
  • the pack 10 comprising the food or beverage ingredient is introduced in a freezer: once it is removed from the freezer, the resulting pack comprises in its inner volume the ingredient in a frozen or semi-frozen state, being therefore made solid or partially solid.
  • the jet Once the jet is created inside the container 30 , it flows through the only free path available which also represents the easiest path for the fluid to flow through (less hydraulic resistance) surrounding the frozen ingredient (therefore develops into a kind of circular movement around the frozen ingredient element). As the jet circulates around the ingredient, it gradually melts it and the cold or chilled product is therefore consequently dispensed through the dispensing fluid outlet 23 .
  • the container 30 comprises an internal sealing 31 as schematically represented in FIG. 3 .
  • the purpose of the internal sealing 31 is to maintain the ingredient or ingredients in an ingredient chamber 32 separated from the rest of the container inner volume: thus, when the pack 10 in introduced in the freezer, the ingredient freezes exclusively inside the chamber 32 avoiding that any product that may have entered the fitment assembly 20 during storage of the pack freezes once the pack is introduced in the freezer, as this may block parts of the fitment assembly preventing a proper introduction of the jet inside the container.
  • the internal sealing 31 is typically configured as a weak internal sealing being breakable under the pressure of the jet introduced inside the container through the injection hole 26 , typically a weak seal breakable at a pressure higher than atmospheric pressure.
  • the pack 10 does not have an internal sealing 31 , then it is preferred that it is introduced in the freezer in a vertical position with the fitment assembly 20 arranged on the upper part of the pack, so that the ingredient inside does not freeze close to the fitment assembly 20 , which can possibly block it.
  • the pack is provided with the internal sealing 31 , it can be positioned inside the freezer in any possible orientation which certainly represents a big advantage for the consumer.
  • the small surface of the injection holes presents the advantage of avoiding any back flow of fluid from the inner volume of the container into the fluid inlets.
  • the surface of the injection hole can vary according to the nature of the ingredients inside the pack.
  • the pack 10 presents a plane shape oriented along a plane essentially vertically oriented during beverage production: the fluid inlets orientate the jet of fluid in a direction comprised in said plane.
  • the food or beverage containers are arranged essentially vertically during the production and dispensing of the product, and the fitment assembly 20 is arranged in such a way that the fluid coming through the fluid inlets is supplied into the containers in an upward direction.
  • the two flexible water impermeable sheets joined to one another to define the inner volume of the container are formed of one single flexible water impermeable sheet folded in half and joined at its free edges.
  • the container is a plane pouch made of a flexible material sheet, said sheet being folded at the top of the container and bonded on its edges to define the inner volume, the bottom bonded edge typically including the fitment assembly 20 .
  • This embodiment constitutes a particularly easy way to manufacture the pack 10 comprising the containers and the fitment assembly 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 fitment assembly 20 is introduced in the bottom edge of the container during the sealing of its edges; previously, the ingredient product has been introduced in the container and the internal sealing has been configured after that.
  • the fluid inlets are typically enclosed in the complete pack 10 by the sheet(s) of material defining the inner volume of the containers: the yieldable cover over the fluid inlets piercable by the injecting means is therefore made by the sheets of material covering these fluid inlets, so it is not necessary to prepare any supplementary cover or membrane to go over them, so the manufacturing is easy and convenient. Consequently the same piece of material can be used to simultaneously create the inner volume of the container and to close the fluid inlets.
  • the invention provides a pack 10 that is easy to manufacture and which guarantees hygienic and shelf life protection of the food and beverage ingredients and of the produced food or beverage product.
  • the introduction of the fitment assembly 20 in the bottom edge of the container during the sealing of its edges to configure the complete pack 10 makes it possible that the flexible sheet can cover the part of the fitment assembly 20 including the fluid inlet. Consequently during the single step of bonding the edges of the sheet, it is possible to simultaneously create the inner volume for storing the food or beverage ingredient, place the fitment assembly 20 and close the fluid inlet.

  • a first energy transfer takes place and the powder part of the product at ⁇ 18° C. in the pack changes its temperature to T 1 by the effect of the water flowing through it while the water part of the ingredient product (ice) changes from ⁇ 18° C. into 0° C.
  • Both heat transfers (of the powder and water parts of the mixture) are given by:
  • the whole product (powder and water) are provided at T 1 at the beverage outlet, as represented in FIG. 6 .
  • a further energy transfer would occur as the cooled product at temperature T 1 would be dispensed into a cup, the cup being provided at ambient temperature of around 23° C.: thus, the cup material would decrease its temperature to T 2 and at the same time the product dispensed would increase its temperature from T 1 into T 2 so that an equilibrium is reached.
  • This heat energy transfer for the product dispensed would be again ruled by:
  • the main advantage of the invention is to achieve the same cold temperature (T 2 ) for the product dispensed departing from a machine or device that injects water at ambient temperature and not needing that cooled water (typically at around 5° C.) is provided. Therefore, the system of the present invention does not need to have a compressor or any cooling module which is the part of the system more costly and complicated.
  • the stored energy in the product (latent heat) cold temperatures of final beverages typically lower than 10° C.
  • FIG. 8 shows the variation of the in-cup product temperature (final targeted value being below 10° C.) and the targeted volumes of standard consumed beverages: the targeted values according to the present invention are for beverages having a volume between 100 ml and 200 ml, preferably between 150 ml and 200 ml.
  • FIG. 8 is a similar graph showing the temperature at the beverage outlet.
  • the invention aims at providing a targeted beverage of a volume comprised between 150 ml and 200 ml at a temperature below 10° C.
  • a device according to the present invention injects a fluid through the fitment assembly 20 of a pack 10 providing a fluid jet circulating inside said pack. It has been proved with this method that, by optimising the recipe of the mixture inside the pack and by targeting at the majority of the product inside to be melted that a mixture having 30 ml of water and 10 g of powder would provide a beverage of 200 ml at 10° C., when 170 ml of water at 23° C. are added inside the pack. In the standard known process, 200 ml of water at 5° C. are added instead.
  • the water part of the mixture of the pack (as it will be further seen from the analysis of Table 2 below) aims at providing the energy needed for the cooling of the beverage in the process, whereas the powder part of the mixture provides the flavour (taste) of the beverage targeted.
  • the quantity of water (fluid) in the mixture will be higher than that of powder.
  • Table 2 shows the estimated amount of energy in percentage that is involved in each process step A i (for the standard process in FIG. 5 ) and B i (for the process of the invention shown in FIG. 6 ).
  • the cooling energy involved in cooling down a 200 ml beverage at 10° C. is entirely given by the water provided at low temperature (5° C.) by the machine.
  • the cooling energy involved in cooling down a 200 ml beverage at 10° C. is mainly given (80%) by the latent heat energy involved in the phase change of the water part of the mixture when it is melted from solid (ice) into liquid; the rest of the cooling energies involved have a much lower influence: 8% comes from the water part of the mixture changing temperature from ⁇ 18° C. into 0° C., 10% from the water part of the mixture changing temperature from 0° C. into T 1 and 2% coming from the powder part of the mixture changing temperature from ⁇ 18° C. into T 1 . The highest part of the energy is therefore involved in the phase change.
  • the invention further refers to a device 40 for preparing cold or chilled food or beverages from a pack 10 as described previously.
  • the device 40 comprises receiving means 42 adapted to accommodate the pack 10 preferably in such a way that the pack is positioned vertically and the fitment assembly 20 is positioned at the bottom of the pack 10 , and injecting means (preferably also being piercing means, typically a fluid needle) designed for engaging with the fitment assembly 20 and for injecting high pressure fluid inside the fluid inlets of the fitment assembly 20 .
  • injecting means preferably also being piercing means, typically a fluid needle
  • the pack 10 will be introduced either frontally in the device (as schematically represented in FIG.
  • the pack 10 will be preferably configured piercable in a reversible way, independently on how it is introduced in the device 40 , it will be processed always in an optimized way.
  • the device further comprises a positioning area 49 for allocating a drinking cup under the dispensing outlet of the pack 10 when a food product or a beverage is prepared.
  • the present invention relates to a method for the preparation of cold or chilled food or beverages from a pack 10 comprising the food or beverage base ingredients as previously described.
  • the method of the invention preferably comprises the following steps:
