Definitions

• the present invention relates to a spout assembly for being used with food or beverage containers; in particular the invention relates to a spout assembly for food or beverage containers comprising at least one ingredient for the preparation of a single or a multiple product.
• 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 As such, different 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. Whereas 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.
• WO 99/05044 describes 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 opening of the closing means 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 this would not be desired for the preparation of tea. Besides, there exists the risk for the user that the packages may not rupture at the desired pressure, and that they would finally open up in an uncontrollable explosion. For this reason the apparatus where the sachet is processed needs to comprise means for totally enclosing the sachet in the machine during beverage preparation in order to avoid damages for the consumer.
• a flexible pouch or sachet for preparing a beverage such as coffee, comprising a space where a concentrated dose of the product is stored.
• the pouch comprises also a rigid part on one of the sides of the pouch, provided with an inlet through which water is inserted into the pouch, a tube element conveying the water towards the opposite part of the pouch, so that the mixing of the water and the ingredient is made, and an outlet through which the product is dispensed.
• the beverage outlet is positioned at the top of the pouch. Water is introduced through the inlet and through the tube element until it fills the pouch and overflows through the beverage outlet positioned at the top of the pouch too.
• Such a pouch is conceived for preparing a beverage by extraction of roast and ground coffee but not by dissolution of instant coffee or other soluble materials. For this reason the pouch comprises a filter at the outlet to prevent insoluble particles from being dispensed with the beverage.
• An inconvenient of such a pouch is that at the end of the preparation of the beverage and the introduction of water, beverage remains in the pouch which is an issue for the user who cannot properly remove the pouch from the beverage production machine.
• neither the water inlet nor the beverage outlet are closed by a membrane, which is not recommended in terms of hygiene and shelf life as it could present problems to the consumer.
• these sachets do not allow the preparation of food or beverage products with multiple ingredients, as already explained for WO 99/05044, and similarly, all the products are processed in the same way, so no optimization of the product dispensed according to the ingredients provided is possible with this system.

• the number of containers correspond to the number of containers that the pack 40 comprises.
• Different sizes of the pack 40, as shown in Figures 12a and 12b can be used in a same machine adapted to store different quantities of ingredients: typically, it is the configuration of the spout assembly 10 as to external shape and piercing requirements of the fluid inlets what determines the machine to use; however, the size of the containers, when extending vertically, as shown in Figures 12a and 12b, does not determine or limit the machine.
• the external design and configuration of the spout assembly 10 will remain unchanged independently on the product targeted; however, the internal design of the spout assembly 10, in particular as to the diameter of the injection holes will differ as a function of the ingredient to be processed and therefore as a function of the food or beverage product targeted. Also, other parameters such as the flow rate of fluid injected and/or the temperature of the fluid injected and/or the total volume of fluid injected, for the single or plurality of containers, will be modified as a function of the ingredient to be processed and therefore as a function of the food or beverage product targeted.
• the range of packs such as described above can comprise at least two types of packs essentially differing by their ability to produce a foamy beverage or a non-foamy beverage.
• the first type of pack that is able to produce a foamy beverage generally presents a water inlet configured for introducing a water jet in the inner volume of the pack with a higher velocity than the second type of pack.
• the first type of pack preferably presents a beverage outlet configured for keeping the beverage as long as possible in the inner volume of the pack.

• the first type of pack also preferably presents a shape configured for improving the movement of the fluid and the beverage in the container during beverage or food preparation. It has been observed that rectangular containers presenting a ratio length/width of about 4/3 and with the spout assembly 10 placed at the width side improve the agitation of the fluid and the generation of foam. This effect is even more accentuated when the spout assembly 10 is positioned at the side corner of the width with the length.
• the foaming of the beverage can also depend from the nature of the food or beverage ingredient.
• the invention enables the production of a range of different packs 40 adapted for the agitation and dissolution of different types of beverage or food ingredients comprised in the containers.
• Each food or beverage container configuring the pack 40 preferably comprises two flexible water impermeable sheets joined to one another to define an inner volume where at least one ingredient for the preparation of a single or multiple product is stored: as shown in Figures 12a-b the spout assembly 10 is preferably arranged in such a way that it brings together the or the plurality of food or beverage containers, in order to provide a sequential extraction of them.
• the food or beverage containers present an essentially plane shape, wherein the spout assembly 10 is arranged on one of the sides of the pack 40.
• the pack itself is substantially flexible and looks like a pouch or sachet. By flexible, it is meant that the sheets can be bent easily.
• the resulting pack 40 can be bent also, as being 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 flexible water impermeable sheets can be formed of one single flexible water impermeable sheet folded in half and joined at its free edges.
• the pack 40 can also comprise an excrescence enabling the handling of the pack 40 by the user or consumer: this has not been shown in the Figures attached, though.

• 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 spout assembly 10.
• This embodiment constitutes a particularly easy way to manufacture the pack 40 comprising the containers and the spout 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 spout assembly 10 is introduced in the bottom edge of the container during the sealing of its edges.
• the water inlets are typically enclosed in the complete pack 40 by the sheet(s) of material defining the inner volume of the containers: the yieldable cover over the fluid inlets piercable by the injecting and piercing means 30 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 40 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 spout assembly 10 in the bottom edge of the container during the sealing of its edges to configure the complete pack 40 makes it possible that the flexible sheet can cover the part of the spout assembly 10 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 spout assembly 10 and close the fluid inlet.
• the dispensing 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 spout assembly 10 comprises ribs 16 arranged in at least one of the external surfaces of the spout assembly 10 for improving the adhesion of the spout with the flexible material sheet during sealing.
• a raising edge can surround the fluid inlet so as to improve air and water tightness around it.

These parameters are also provided together with the information on the sequential processing of the single or plurality of containers configuring the pack.
• two sets of symmetrically arranged identification means 60 are arranged in the pack, so that the process parameters in the identification means 60 can be reversibly read (when made as punching holes, these holes are punched on both reversible sides of the pack, frontal and reverse; as the identification means 60 are also arranged on the two lateral sides of the pack, they can therefore be read no matter the way the pack is introduced in the machine).
• the pack 40 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 present invention presents the advantage of proposing packs for the preparation of food or beverages wherein a broad range of different foods and beverages can be produced with the same machine.
• the foods and beverages can differ by their nature (coffee, tea, chocolate, soup, etc.), by their aspect (presence of foam for coffee, of foam for milk and chocolate, absence of bubbles for tea, etc.), by their volume (from espresso volume up to soup volume) and still be obtained by the same machine.
• the machine elements can remain very simple and limited to a simple fluid needle, typically a simple water needle.
• the present invention presents the advantage of proposing a consumer friendly preparation of foods and beverages.
• the beverage of food delivered from the pack is ready to be served and does not require any additional process step, for example for foaming the beverage.
• the present invention also presents the advantage of proposing packs wherein the ingredients are fully protected from atmosphere before use.
• the present invention presents the advantage of proposing packs for preparing beverages or food products wherein the contact of ingredients and prepared beverage or food product with the machine is avoided and the risk of cross contamination is therefore limited.
• the prepared beverages or food products present optimal organoleptic properties.
• the present invention further presents the advantage of proposing packs presenting a low environmental impact since they can be made of a laminated pouch with a small insert piece (spout assembly) of plastic.
• the present invention presents the advantage of proposing packs which can be very easily produced starting from flexible sheets and one single spout assembly inserted.
• the pack usually does not comprise an internal filter or membrane to be positioned in the inner volume during manufacturing.
• the packs of the present invention comprise in one single and grouped package a recipe to be prepared when the pack comprises more than one container, so that a sequential preparation is followed. Reduced manipulations to be done on the side of the consumer are also a big advantage on the user's side. Moreover, best in-cup results can be achieved as the extraction and processing sequence is pre-defined and in fact comprised in the information on the identification means 60. Another very important advantage of the packs of the invention is that the packs comprising one container and those comprising a plurality of containers are compatible and can be used in a same machine having the same brewing unit.

• the spout assembly comprising one composing part or two composing parts has exactly the same outer shape so the same machine can be used for the two configurations, and also has similar fluid inlet piercing need, which allows the use of same compatible needles configuration.
• identification means in the pack not only the physical configuration and mechanical needs are the same for the packs, independently on the sense in which they are introduced in the machine, making it possible that they can be processed/operated in one sense or the other, but the identification means further provide the information to the machine which allows the machine to know the correct sequence of processing of the container or containers in the pack.
• the main goal of the spout assembly designed according to the present invention is that, either when made of one single composing part or when made of two composing parts attached together, the resulting spout assembly is in both cases compatible and can be used in the same machine.
• Another primary advantage of the invention lies in the fact that the spout assembly, when made out of one single composing part, has exactly the same outer shape in both sides, which allows that there exists no crippling of the flexible sheets when they are welded onto the spout assembly. Moreover, the same outer shape on both sides of the spout assembly is also provided when the spout assembly is made out of two composing parts attached together, again avoiding any crippling risk.
