Description

L'invention concerne une dosette pour la préparation de boisson infusée, ainsi qu'un ensemble comprenant une telle dosette et une machine associée pour préparer cette boisson.The invention relates to a pod for the preparation of infused beverage, and an assembly comprising such a pod and a machine associated to prepare the beverage.

1. Domaine de l'invention1. Field of the invention

La présente invention concerne le domaine du conditionnement et de la préparation de boissons infusées à base de thé, café, cacao, herbes aromatiques, etc.The present invention relates to the field of packaging and preparation of infused beverages based on tea, coffee, cocoa, herbs, etc.

2. Art antérieur2. Prior Art

Il existe sur le marché différentes dosettes pour la préparation de boissons infusées. On en connaît qui sont des sachets comprenant une enveloppe souple entourant un volume contenant une substance à infuser. Cependant, ces sachets ne présentent pas une mouillabilité suffisante. Le liquide, au cours de l'extraction, reste chargé en éléments déjà extraits pour le reste de l'infusion. De plus, pour permettre une bonne infusion, il est conseillé que l'utilisateur agite la dosette deux à cinq minutes environ. Une utilisation dans une machine qui délivre automatiquement du liquide chaud est peu ou pas adaptée. Un exemple de réalisation est divulgué dans le document EP2164779 .There are different pods on the market for the preparation of infused drinks. It is known which are bags comprising a flexible envelope surrounding a volume containing a substance to be infused. However, these bags do not have sufficient wettability. The liquid, during extraction, remains loaded with elements already extracted for the rest of the infusion. In addition, to allow a good infusion, it is advised that the user shakes the pod for two to five minutes. Use in a machine that automatically delivers hot liquid is little or not suitable. An exemplary embodiment is disclosed in the document EP2164779 .

On connaît aussi les dosettes dites « capsule » ou « recharge » typiquement opaques et rigides. On ne peut pas juger de la bonne expansion de la substance à infuser contenue, ni des conditions de l'infusion. Un exemple de capsule est divulgué dans EP1816936 .We also know pods called "capsule" or "refill" typically opaque and rigid. We can not judge the good expansion of the substance to be infused contained, or the conditions of the infusion. An example of a capsule is disclosed in EP1816936 .

3. Objectif de l'invention3. Objective of the invention

L'invention a notamment pour objectif de pallier tout ou partie des inconvénients de l'art antérieur.The invention particularly aims to overcome all or part of the disadvantages of the prior art.

Plus précisément, un objectif de l'invention est de fournir, pour la préparation de boisson infusée, une dosette ou un ensemble dosette/machine qui améliore, facilite et/ou accélère l'extraction des substances à infuser, tout en étant simple à fabriquer et à utiliser et qui soit peu couteuse.More specifically, an object of the invention is to provide, for the preparation of infused beverage, a pod or a pod / machine that improves, facilitates and / or accelerates the extraction of substances to be infused, while being simple to manufacture and to use and that is inexpensive.

4. Résumé de l'invention4. Summary of the invention

Cet objectif est atteint grâce à :

  • un ensemble pour préparer une boisson infusée comprenant une dosette comportant une enveloppe souple et perméable qui entoure un volume contenant une substance à infuser ; une machine de préparation de boisson ; et, au moins un moyen de canalisation d'un liquide s'étendant à l'intérieur du volume de l'enveloppe pour y acheminer le liquide, dans un état fonctionnel, le moyen de canalisation présentant dans volume de l'enveloppe au moins un passage pour faire passer le liquide vers la substance à infuser ;
  • une dite dosette comportant une enveloppe telle que susmentionnée, cette dosette comprenant un moyen de canalisation d'un liquide pour l'infusion s'étendant à l'intérieur du volume de l'enveloppe pour y acheminer le liquide et présentant, dans le volume de l'enveloppe, au moins un passage pour faire passer le liquide vers la substance à infuser ; ou, un orifice pour recevoir un moyen de canalisation de façon qu'il puisse s'étendre à l'intérieur de l'enveloppe, le moyen de canalisation présentant au moins un passage pour faire passer un liquide vers la substance à infuser.
This goal is achieved through:
  • an assembly for preparing a brewed beverage comprising a pod having a flexible and permeable envelope surrounding a volume containing a substance to be infused; a beverage preparation machine; and, at least one means for channeling a liquid extending inside the volume of the envelope to convey the liquid, in a functional state, the channeling means having in volume of the envelope at least one passage to pass the liquid to the substance to be infused;
  • a said pod comprising an envelope as mentioned above, this pod comprising means for channeling a liquid for infusion extending inside the volume of the envelope to convey the liquid and having, in the volume of the envelope, at least one passage for passing the liquid to the substance to be infused; or, an orifice for receiving a channeling means so that it can extend to inside the envelope, the channeling means having at least one passage for passing a liquid to the substance to be infused.

Comme il est décrit plus loin, on prévoit de manière alternative ou en complément que la machine comprenne au moins un moyen de canalisation et que la dosette présente un accès pour le recevoir.As described below, it is provided alternately or in addition that the machine comprises at least one channeling means and that the pod has access to receive it.

Cet agencement permet une mise en contact rapide du liquide et des substances à infuser au coeur de la dosette, ce qui engendre une expansion et une infusion performante.This arrangement allows a rapid contact of the liquid and substances to be infused into the heart of the pod, which causes expansion and infusion performance.

Selon une caractéristique avantageuse, le moyen de canalisation présente une structure maillée. Ceci favorise les contacts entre le liquide et la substance.According to an advantageous characteristic, the channeling means has a mesh structure. This promotes contact between the liquid and the substance.

Selon une autre caractéristique avantageuse, le moyen de canalisation présente une paroi comportant ledit passage lequel est orienté transversalement (à la direction d'entrée de liquide dans la dosette via ladite ouverture) de manière à dévier une partie au moins du liquide latéralement.According to another advantageous characteristic, the channeling means has a wall comprising said passage which is oriented transversely (to the liquid inlet direction in the pod via said opening) so as to deflect at least a portion of the liquid laterally.

De manière préférée, ledit passage dévie latéralement le liquide par rapport à une direction principale d'allongement du moyen de canalisation.Preferably, said passage laterally deflects the liquid with respect to a main direction of elongation of the channeling means.

On obtient ainsi une répartition optimisée du flux qui permet de soulever, par exemple, les feuilles de thé en créant un phénomène d'agitation à l'intérieur de la dosette de sorte à accélérer le processus d'extraction. De plus, on note que les substances à infuser ne sont pas plaquées vers le fond de la dosette.This provides an optimized distribution of the flow that can lift, for example, tea leaves by creating a stirring phenomenon inside the pod so as to accelerate the extraction process. In addition, it is noted that the substances to be infused are not plated towards the bottom of the pod.

On peut prévoir que la paroi du moyen de canalisation soit pleine. Dans ce cas on obtient une bonne orientation du débit, lequel peut être plus important.It can be provided that the wall of the channeling means is full. In this case we obtain a good orientation of the flow, which can be more important.

Selon un autre mode de réalisation, le moyen de canalisation comporte un tube en un matériau plus rigide que celui de l'enveloppe souple. Cette caractéristique permet une bonne manipulation de la dosette et un transfert du liquide favorable dans la dosette.According to another embodiment, the channeling means comprises a tube made of a material that is more rigid than that of the flexible envelope. This characteristic allows a good handling of the pod and a transfer of the favorable liquid in the pod.

Selon une autre caractéristique importante, le moyen de canalisation et l'enveloppe souple sont deux pièces séparées liées ensemble par au moins un moyen de fixation.According to another important characteristic, the channeling means and the flexible envelope are two separate parts joined together by at least one fastening means.

Cela permet notamment de faciliter la fabrication des différents moyens. Ceci permet un gain de temps dans la réalisation de l'enveloppe.This allows in particular to facilitate the manufacture of different means. This allows a saving of time in the realization of the envelope.

Selon un autre mode de réalisation, le moyen de fixation comporte une structure intermédiaire disposée entre l'enveloppe souple et le moyen de canalisation, la structure intermédiaire est fixée à l'enveloppe et est plus rigide ou aussi souple que l'enveloppe souple.According to another embodiment, the fastening means comprises an intermediate structure disposed between the flexible envelope and the channeling means, the intermediate structure is fixed to the envelope and is more rigid or as flexible as the flexible envelope.

Cet agencement permet une bonne maniabilité de la dosette ainsi qu'une bonne tenue de celle-ci, en particulier sur une machine de distribution de liquide.This arrangement allows a good handling of the pod and a good hold thereof, particularly on a liquid dispensing machine.

Selon une autre caractéristique, l'enveloppe souple est constituée d'une matière filtrante. Ceci empêche facilement le passage des feuilles tout en laissant passer le liquide.According to another feature, the flexible envelope consists of a filter material. This easily prevents the passage of leaves while allowing the liquid to pass.

Avantageusement, la dosette comporte des éléments de fixation adaptés à être fixés de façon amovible à des moyens complémentaires de connexion de la machine de préparation de boisson, pour y maintenir ledit élément de fixation.Advantageously, the pod comprises fixing elements adapted to be removably attached to complementary means of connection of the beverage preparation machine, to maintain said fixing member.

De la sorte la dosette est applicable aisément à la machine et le maintien de celle-ci lors du fonctionnement de la machine est prévu.In this way the pod is easily applicable to the machine and the maintenance thereof during operation of the machine is provided.

Selon une caractéristique remarquable, la machine pourra donc comprendre au moins le moyen de canalisation et la dosette présentera un accès pour le recevoir.According to a remarkable characteristic, the machine can therefore include at least the channeling means and the pod will have access to receive it.

Selon une caractéristique avantageuse, l'accès comprend un orifice dans la pièce intermédiaire. De la sorte le moyen de canalisation est mieux guidé vers l'intérieur de l'enveloppe et le maintien de celui-ci est facilité.According to an advantageous characteristic, the access comprises an orifice in the intermediate piece. In this way the channeling means is better guided towards the inside of the envelope and the maintenance of it is facilitated.

L'enveloppe souple peut être formée d'une unique feuille souple formée en poche, ou, de plusieurs feuilles souples assemblées à leurs bords pour permettre à l'enveloppe d'être tant aplatie que développée en volume. Ainsi on peut optimiser le conditionnement des dosettes et, lors de leur utilisation, favoriser le déploiement volumique transversal de l'enveloppe par rapport à la direction suivant laquelle s'étend le moyen de canalisation.The flexible envelope may be formed of a single flexible sheet formed in a pocket, or of several flexible sheets assembled at their edges to allow the envelope to be both flattened and expanded in volume. Thus, the packaging of the pods can be optimized and, when they are used, favor the transverse volume deployment of the envelope relative to the direction along which the channeling means extends.

Toujours dans le but d'améliorer le déploiement de l'enveloppe souple, cette dernière peut présenter un ou plusieurs plis pour un déploiement volumique transversal par rapport à la direction suivant laquelle s'étend le moyen de canalisation, ou plusieurs plis enroulés dans un état conditionné de la dosette.Still with the aim of improving the deployment of the flexible envelope, the latter may have one or more folds for a transverse volume deployment relative to the direction along which the channeling means extends, or several folds wound in a conditioned state of the pod.

Dans le cas de la dosette comprenant le moyen de canalisation, le moyen de fixation comporte une pièce intermédiaire disposée entre l'enveloppe souple et le moyen de canalisation, lequel est porté par la pièce intermédiaire qui est fixée à l'enveloppe souple et est plus rigide ou aussi souple que l'enveloppe souple. Cet agencement permet une bonne maniabilité de la dosette ainsi qu'une bonne tenue de celle-ci, en particulier sur une machine de distribution de liquide.In the case of the pod comprising the channeling means, the fixing means comprises an intermediate piece disposed between the flexible envelope and the channeling means, which is carried by the intermediate piece which is fixed to the flexible envelope and is more rigid or as flexible as the flexible envelope. This arrangement allows a good handling of the pod and a good hold thereof, particularly on a liquid dispensing machine.

Encore dans le cas de la dosette comprenant le moyen de canalisation, ce dernier et l'enveloppe souple sont séparés l'un de l'autre par une structure intermédiaire qui est formée en une seule pièce avec le moyen de canalisation.Again in the case of the pod comprising the channeling means, the latter and the flexible envelope are separated from each other by an intermediate structure which is formed in one piece with the channeling means.

Un tel agencement permet une fabrication aisée de ces deux structures et notamment un gain de temps.Such an arrangement allows easy manufacture of these two structures and in particular a time saving.

4. Description détaillée4. Detailed description

La figure 1 présente donc un exemple de dosette 1 pour la préparation de boisson infusée. Ces dosettes 1 sont généralement connues sous le terme de « sachet » pour les utilisations traditionnelles, par exemple dans une tasse ou une théière ou sous le terme de « capsule » ou « recharge » pour l'utilisation d'une machine de préparation de boisson. La dosette est utilisable sur une telle machine.The figure 1 therefore presents an example of a pod 1 for the preparation of infused beverage. These pods 1 are generally known by the term "sachet" for traditional uses, for example in a cup or teapot or under the term "capsule" or "refill" for the use of a machine for preparing drinks. . The pod is usable on such a machine.

La dosette 1 comporte une enveloppe 2 souple, donc déformable, qui entoure et détermine un volume fermé 2a contenant une substance à infuser la (représentée figures 1, 4, 14 et 17, mais systématiquement prévue pour les autres figures) du genre thé, café, cacao ou tout autre élément pouvant être infusé sous forme, en particulier de feuilles, poudres, morceaux ou grains.The pod 1 comprises a flexible envelope 2, therefore deformable, which surrounds and determines a closed volume 2a containing a substance to infuse the (shown Figures 1, 4 , 14 and 17 , but systematically provided for the other figures) of the kind tea, coffee, cocoa or any other element that can be infused into form, in particular sheets, powders, pieces or grains.

De manière préférée, l'enveloppe 2 renferme des feuilles de thé entières, ou plus ou moins déchiquetées.Preferably, the envelope 2 contains whole tea leaves, or more or less shredded.

L'enveloppe 2 présente une paroi 15 perméable au liquide infusé. Avantageusement, toute la paroi de l'enveloppe est perméable, en particulier, la paroi qui entoure la substance à infuser. L'enveloppe 2 peut être constituée d'une matière filtrante et/ou perméable au liquide et/ou qui empêche le passage des feuilles tout en laissant passer le liquide. De manière avantageuse cette matière filtrante et/ou perméable est réalisée en polymère ou en polymère biodégradable. L'enveloppe 2 peut être entièrement constituée d'un filet ou tulle, non tissé, comportant un maillage et donc des ouvertures laissant passer le liquide ou d'un matériau tissé de préférence en PLA (acide polylactique) ou polyamide, dans un grammage compris entre 5 et 150 g/m2). La paroi 15 possède ainsi une bonne mouillabilité ainsi qu'une flexibilité favorable à l'expansion de la substance à infuser 1a.The casing 2 has a wall 15 permeable to the infused liquid. Advantageously, the entire wall of the envelope is permeable, in particular, the wall that surrounds the substance to be infused. The casing 2 may consist of a filter material and / or permeable to the liquid and / or which prevents the passage of leaves while allowing the liquid to pass. Advantageously this filtering material and / or permeable is made of polymer or biodegradable polymer. The envelope 2 may be entirely made of a net or tulle, non-woven, having a mesh and therefore openings allowing the liquid to pass or a woven material preferably made of PLA (polylactic acid) or polyamide, in a grammage between 5 and 150 g / m 2 ). The wall 15 thus has a good wettability and a flexibility favorable to the expansion of the substance to infuse 1a.

Selon un premier mode de réalisation de l'invention illustré sur la figure 1, la dosette 1 comporte au moins un moyen de canalisation 3 d'un liquide pour l'infusion s'étendant à l'intérieur du volume de l'enveloppe 2. On entend par « étendre à l'intérieur », une longueur ou une prolongation du moyen de canalisation à l'intérieur du volume de l'enveloppe. En particulier le moyen de canalisation 3 est lié à l'enveloppe 2.According to a first embodiment of the invention illustrated on the figure 1 , the pod 1 comprises at least one channeling means 3 of a liquid for infusion extending inside the volume of the casing 2. "Extending inside" means a length or a extension of the channeling means within the volume of the envelope. In particular the channeling means 3 is connected to the casing 2.

Dans un autre mode de réalisation décrit plus loin, la dosette 1 peut comporter un orifice 30 pour recevoir un moyen de canalisation.In another embodiment described below, the pod 1 may include an orifice 30 for receiving a channeling means.

Le moyen de canalisation 3 comporte une ouverture 4 par laquelle le liquide est introduit, une paroi 5 pour acheminer le liquide et au moins un passage 6 ou trou pour faire passer le liquide du moyen de canalisation 3 vers la substance à infuser 1a. Il résulte de cet agencement, que la substance à infuser 1a est mise en contact directement avec le liquide, et ce liquide « neuf » n'est pas chargé en élément extrait, ce qui améliore la qualité de l'infusion.The channeling means 3 comprises an opening 4 through which the liquid is introduced, a wall 5 for conveying the liquid and at least one passage 6 or hole for passing the liquid from the channeling means 3 to the substance to be infused 1a. As a result of this arrangement, the substance to be infused 1a is brought into direct contact with the liquid, and this "new" liquid is not loaded in extracted element, which improves the quality of the infusion.

Le moyen de canalisation 3 peut présenter une structure maillée. Dans ce cas la paroi 5 peut être constituée par exemple d'un filet ou tulle comprenant des ouvertures ou mailles pouvant laisser passer le liquide à travers les mailles. Cette structure maillée peut être composée de filet souple ou rigide par rapport à l'enveloppe 2. La rigidité de la structure maillée peut être aussi apportée par l'utilisation d'un polymère rigide pour la paroi 5 dans laquelle des ouvertures régulières sont formées (voir figure 5).The channeling means 3 may have a mesh structure. In this case the wall 5 may consist for example of a net or tulle comprising openings or meshes that can pass the liquid through the mesh. This mesh structure can be made of flexible or rigid mesh with respect to the envelope 2. The rigidity of the mesh structure can also be provided by the use of a rigid polymer for the wall 5 in which regular openings are formed (see figure 5 ).

De manière préférée, le moyen de canalisation 3 présente une paroi 5 pleine, c'est-à-dire sans mailles.Preferably, the channeling means 3 has a wall 5 full, that is to say without meshes.

La paroi 5 comporte au moins un passage 6 orienté transversalement, de sorte à dévier une partie au moins du liquide latéralement. Le ou les passage(s) 6 dévie(nt) le liquide latéralement, selon une direction transversale, par rapport à une direction 14 principale d'allongement du moyen de canalisation 3, vers le centre de l'enveloppe 2. L'enveloppe présente une longueur principale qui s'étend également selon la direction 14, de sorte que le moyen de canalisation et l'enveloppe s'étendent sensiblement dans cette même direction 14 principale d'allongement. Les passages 6 permettent de répartir le flux de liquide en gardant la capacité à agiter la substance à infuser.The wall 5 has at least one passage 6 oriented transversely, so as to deflect at least a portion of the liquid laterally. The passage (s) 6 deflects (the) the liquid laterally, in a transverse direction, with respect to a main direction 14 of elongation of the channeling means 3, towards the center of the envelope 2. The envelope presents a main length which also extends in the direction 14, so that the channeling means and the envelope extend substantially in the same direction 14 main elongation. The passages 6 make it possible to distribute the flow of liquid while keeping the capacity to agitate the substance to be infused.

Le moyen de canalisation 3 peut se présenter sous la forme d'un tube 10 dans lequel le liquide s'écoule pour infuser la substance 1a. Ce tube 10 est constitué en un matériau plus rigide que celui de l'enveloppe 2. Le matériau du tube 10 peut être identique à celui de l'enveloppe 2 mais plus rigide et/ou doit être compatible avec celui de l'enveloppe souple 2.The channeling means 3 may be in the form of a tube 10 in which the liquid flows to infuse the substance 1a. This tube 10 is made of a more rigid material than that of the casing 2. The material of the tube 10 may be identical to that of the casing 2 but more rigid and / or must be compatible with that of the flexible casing 2 .

On peut prévoir que le moyen de canalisation 3 s'étende à environ deux-tiers de la hauteur H de l'enveloppe 2, voire être en contact avec le fond 9 de l'enveloppe 2. La paroi 5 peut comporter plusieurs passages 6 (voir figure 8) qui peuvent être de toute forme et être disposés le long de la paroi 5 ou à une extrémité 7 proche de l'ouverture 4 et/ou à une extrémité 8 située vers le fond 9 de l'enveloppe 2.Provision can be made for the channeling means 3 to extend about two-thirds of the height H of the envelope 2, or even to be in contact with the bottom 9 of the envelope 2. The wall 5 may comprise several passages 6 (see figure 8 ) which may be of any shape and may be arranged along the wall 5 or at an end 7 close to the opening 4 and / or at an end 8 located towards the bottom 9 of the casing 2.

Le liquide qui arrive en sortie du moyen de canalisation 3 par les passages 6 crée un flux et un déplacement de la substance 1a à l'intérieur de la dosette 1.The liquid that arrives at the outlet of the channeling means 3 through the passages 6 creates a flow and a displacement of the substance 1a inside the pod 1.

Le moyen de canalisation 3 et l'enveloppe 2 sont deux pièces séparées liés ensemble par un moyen de fixation.The channeling means 3 and the casing 2 are two separate pieces joined together by a fixing means.

Sur la figure 1, le moyen de canalisation 3 et l'enveloppe 2 sont en contact l'un avec l'autre, en particulier, l'enveloppe 2 est en contact avec la paroi 5. Ceux-ci sont fixés ensemble grâce à une soudure ou une colle 26 ou tout autre moyen permettant de fixer ces éléments ensemble.On the figure 1 , the channeling means 3 and the casing 2 are in contact with each other, in particular, the casing 2 is in contact with the wall 5. These are fixed together by means of a weld or glue 26 or any other means to fix these elements together.

Sur les figures 2 à 7, 11, 12 et 15, le moyen de fixation peut comporter une structure intermédiaire 11. Cette dernière peut être disposée entre l'enveloppe souple 2 et le moyen de canalisation 3. Celui-ci est porté par la structure intermédiaire 11 qui est fixée à l'enveloppe 2, vers une extrémité de la paroi 15 de celle-ci. Pour cela, la structure 11 est munie d'un bord périphérique 28 auquel peut être fixée, par exemple, par soudure ou collage ou tout autre élément de fixation, la bordure 29 de l'enveloppe 2.On the Figures 2 to 7 , 11, 12 and 15 the fixing means may comprise an intermediate structure 11. The latter may be disposed between the flexible envelope 2 and the channeling means 3. This is carried by the intermediate structure 11 which is fixed to the envelope 2, to one end of the wall 15 thereof. For this, the structure 11 is provided with a peripheral edge 28 to which may be fixed, for example, by welding or gluing or any other fastening element, the border 29 of the casing 2.

La structure intermédiaire 11 peut être plus rigide ou aussi souple que l'enveloppe 2 souple. La structure intermédiaire 11 permet également de créer une enveloppe 2 en forme de poche ce qui permettra une meilleure expansion de la substance 1a à infuser.The intermediate structure 11 may be more rigid or as flexible as the flexible envelope 2. The intermediate structure 11 also makes it possible to create a bag-shaped envelope 2 which will allow a better expansion of the substance 1a to be infused.

Plus précisément encore, la structure intermédiaire 11, plus rigide par exemple sur les figures 2, 6, 7, 11 et 12 forme une collerette autour du moyen de canalisation 3 porté par la structure 11.More precisely still, the intermediate structure 11, which is more rigid for example on the Figures 2, 6 , 7 , 11 and 12 forms a flange around the channeling means 3 carried by the structure 11.

A noter que le moyen de canalisation 3 peut être fixé à cette structure 11 par une soudure ou une colle 26. Bien entendu, la structure 11 et le moyen de canalisation peuvent être formés d'une seule pièce (figures 11 et 12).Note that the channeling means 3 can be fixed to this structure 11 by a weld or glue 26. Of course, the structure 11 and the channeling means can be formed in one piece ( Figures 11 and 12 ).

On peut prévoir que l'extrémité 8 du moyen de canalisation 3 soit fixée avec le fond 9 de l'enveloppe 2 au moyen, par exemple, de colle ou soudure 26.It can be provided that the end 8 of the channeling means 3 is fixed with the bottom 9 of the casing 2 by means of, for example, glue or solder 26.

Sur les figures 11 et 12, les passages 6 sont localisés à proximité de chaque extrémité 7, 8 de la paroi 5 du moyen de canalisation 3. Sur la figure 11, les passages 6 sont orientés (symétriquement) de biais par rapport à la direction 14 d'allongement du moyen de canalisation 3. Le liquide sortant des passages 6 est alors orienté vers la structure 11. Selon cet agencement, le flux arrivant sur la surface interne 27 de la structure 11 rigide, au regard de l'intérieur de l'enveloppe 2, est redirigé vers l'intérieur de la dosette 1 de sorte à créer un brassage plus efficace des substances 1a et éviter le plaquage des feuilles sur la paroi 15 de l'enveloppe 2. La surface interne 27 peut comporter des stries (non représentées) pour favoriser le brassage. Sur la figure 12, les passages 6 proches de l'extrémité 7 du moyen de canalisation sont orientés vers l'intérieur de l'enveloppe souple. Cependant, les avantages résultant de cet agencement sont similaires à ceux développés en rapport avec la figure 11.On the Figures 11 and 12 , the passages 6 are located near each end 7, 8 of the wall 5 of the channeling means 3. On the figure 11 , the passages 6 are oriented (symmetrically) obliquely with respect to the direction 14 of elongation of the channeling means 3. The liquid leaving the passages 6 is then oriented towards the structure 11. According to this arrangement, the flow arriving on the surface internal 27 of the rigid structure 11, facing the inside of the casing 2, is redirected to the inside of the pod 1 so as to create a more effective mixing of the substances 1a and avoid the plating of the sheets on the wall 15 of the envelope 2. The internal surface 27 may include ridges (not shown) to promote mixing. On the figure 12 the passages 6 near the end 7 of the channeling means are oriented towards the inside of the flexible envelope. However, the advantages resulting from this arrangement are similar to those developed in connection with the figure 11 .

Les passages 6 peuvent être disposés de manière décalée. En particulier, un passage 6 situé à l'extrémité 7 peut présenter, par exemple, un décalage représentant un angle de 45° par rapport à un passage 6 disposé à l'extrémité 8.The passages 6 may be arranged in an offset manner. In particular, a passage 6 at the end 7 may have, for example, an offset representing an angle of 45 ° with respect to a passage 6 disposed at the end 8.

Sur les figures 3, 4 et 5, la structure intermédiaire 11 est aussi souple que l'enveloppe souple 2. En effet, la structure intermédiaire 11 peut être constituée du même matériau utilisé pour l'enveloppe 2, à savoir en polymère ou polymère biodégradable. Pour plus de tenue, la structure 11 peut être doublée. Tous ces éléments sont fixés ensemble par soudage ou collage ou autre.On the Figures 3, 4 and 5 the intermediate structure 11 is as flexible as the flexible envelope 2. Indeed, the intermediate structure 11 may be made of the same material used for the envelope 2, namely polymer or biodegradable polymer. For more strength, the structure 11 can be doubled. All these elements are fixed together by welding or gluing or other.

Comme on peut le voir sur les figures 5 à 7, chaque extrémité de l'enveloppe 2 peut comporter une structure 11, 11'. Le moyen de canalisation peut s'étendre, par exemple à environ deux-tiers de l'enveloppe 2 ou s'étendre d'une structure 11, 11' à l'autre. Toutefois, le moyen de canalisation 3 ne comporte qu'une seule ouverture 4 pour l'introduction du liquide. Les deux structures intermédiaires 11, 11' peuvent être souples. La seconde structure intermédiaire 11' peut être souple (figure 5) ou rigide ou semi-rigide (figures 6 et 7) par rapport à l'enveloppe 2 de sorte à garantir un volume tridimensionnel de l'enveloppe 2 et un maintien de la dosette 1.As can be seen on the Figures 5 to 7 each end of the envelope 2 may comprise a structure 11, 11 '. The channeling means may extend, for example to about two-thirds of the casing 2 or extend from one structure 11, 11 'to the other. However, the channeling means 3 has only one opening 4 for the introduction of the liquid. The two intermediate structures 11, 11 'can be flexible. The second intermediate structure 11 'can be flexible ( figure 5 ) or rigid or semi-rigid ( figures 6 and 7 ) relative to the casing 2 so as to ensure a three-dimensional volume of the casing 2 and a maintenance of the pod 1.

L'enveloppe 2 peut être formée d'une unique feuille souple 16 comme illustré, par exemple sur la figure 1. La feuille 16 souple est repliée sur elle-même en direction du moyen de canalisation 3, par exemple, pour former une poche laquelle contient la substance 1a à infuser. On peut prévoir que cette unique feuille 16 soit pliée autour d'une structure 11 et soudée sur le bord périphérique 28 de celui-ci pour former la poche. Toutefois, l'enveloppe 2 peut être formée d'un assemblage de plusieurs feuilles 16' souples (voir figures 2 et 3). Il peut y avoir environ quatre, voire six feuilles 16' assemblées chacune à leurs bords 21, par exemple, par soudage ou collage ou autre pour former la poche. Cet assemblage de feuilles 16' autorise un aplatissement de l'enveloppe 2 pour le conditionnement de la dosette dans les boîtes prévues à cet effet et un développement en volume lorsque, par exemple, la substance 1a qu'elle contient se dilate.The envelope 2 may be formed of a single flexible sheet 16 as illustrated, for example on the figure 1 . The flexible sheet 16 is folded on itself in the direction of the channeling means 3, for example, to form a pocket which contains the substance 1a to be infused. It can be provided that this single sheet 16 is folded around a structure 11 and welded to the peripheral edge 28 thereof to form the pocket. However, the envelope 2 may be formed of an assembly of several flexible sheets 16 '(see Figures 2 and 3 ). There may be about four or even six 16 'sheets each assembled at their edges 21, for example, by welding or gluing or the like to form the pocket. This assembly of sheets 16 'allows a flattening of the envelope 2 for the packaging of the pod in the boxes provided for this purpose and a development in volume when, for example, the substance 1a it contains expands.

L'enveloppe souple 2 peut également présenter un ou plusieurs plis 17 (voir figure 6). Ces plis 17 ou fronces sont réalisés par pliage de la feuille 16, 16' sur toute la hauteur de l'enveloppe 2 et sont maintenus en place par soudage ou collage ou autre sur une ou deux structures intermédiaire 11, 11', Ces plis 17 permettent un déploiement volumique transversal par rapport à la direction 14 d'allongement suivant laquelle s'étend le moyen de canalisation 3. Ces plis 17 peuvent également être enroulés. L'enroulement des plis est alors maintenu en place en particulier lorsque la dosette 1 est conditionnée.The flexible envelope 2 may also have one or more pleats 17 (see figure 6 ). These folds 17 or folds are made by folding the sheet 16, 16 'over the entire height of the casing 2 and are held in place by welding or gluing or other on one or two intermediate structures 11, 11', These folds 17 allow a transverse volume deployment with respect to the elongation direction 14 along which the 3. These folds 17 may also be wound. The winding of the folds is then held in place especially when the pod 1 is packaged.

L'enveloppe 2 peut présenter toute sorte de section, notamment une section en forme de croix (figure 8) permettant son pliage et son conditionnement et, bien entendu, le déploiement volumique.The envelope 2 may have any kind of section, in particular a section in the form of a cross ( figure 8 ) allowing its folding and packaging and, of course, the volume deployment.

La dosette 1 comprend encore des moyens permettant de suspendre l'enveloppe 2 au-dessus, par exemple, d'un récipient. En particulier, ces moyens pour suspendre sont constitués de languettes 18 qui, en situation d'utilisation, s'étendent au-delà de la paroi 15 de l'enveloppe 2. Sur la figure 8, les languettes 18 peuvent constituer la structure 11 qui porte le moyen de canalisation 3. Selon une possibilité, les languettes 18 comportent une encoche 20 sur leur bordure inférieure 22 destinée à reposer sur le bord supérieure d'un récipient, un verre par exemple.The pod 1 further comprises means for suspending the envelope 2 above, for example, a container. In particular, these means for suspending consist of tongues 18 which, in use, extend beyond the wall 15 of the envelope 2. figure 8 , the tabs 18 may constitute the structure 11 which carries the channeling means 3. According to one possibility, the tabs 18 have a notch 20 on their lower edge 22 intended to rest on the upper edge of a container, a glass for example.

Concernant les figures 9, 10a et 10b, ces languettes 18 peuvent être fixées, par exemple, de part et d'autre de l'enveloppe 2 et en partie haute de la paroi 15 de celle-ci. Les languettes 18 sont repliées pour former une première partie 23 fixée sur la paroi 15 de l'enveloppe 2 et une deuxième partie formant une aile 19, 19', cette dernière étant destinée à reposer à l'extérieur de la surface d'un récipient, par exemple, pour suspendre la dosette 1. Dans ce cas présent, cette languette 18 peut également servir de moyen de préhension pour ouvrir la dosette 1 de sorte à accéder au moyen de canalisation 3, 300.About the Figures 9, 10a and 10b these tabs 18 can be fixed, for example, on either side of the casing 2 and in the upper part of the wall 15 thereof. The tongues 18 are folded to form a first portion 23 fixed on the wall 15 of the casing 2 and a second portion forming a wing 19, 19 ', the latter being intended to rest outside the surface of a container for example, to suspend the pod 1. In this case, this tab 18 can also serve as a gripping means to open the door. pod 1 to access the channeling means 3, 300.

Les languettes 18 peuvent être réalisées en carton ou en plastique par exemple. Elles doivent être suffisamment rigides pour supporter la dosette 1 sur un récipient.The tongues 18 may be made of cardboard or plastic for example. They must be rigid enough to support the pod 1 on a container.

La dosette 1 étant favorablement prévue pour être utilisée sur une machine de préparation de boisson, on recommande que cette dosette 1 comporte un élément de fixation 24 adapté à être connecté, de façon amovible, à des moyens complémentaires 25 d'une machine 50 de préparation de boisson. Comme on peut le voir sur les figures 18 et 19, une fois la dosette 1 ainsi fixée à la machine 50, l'ouverture 4 du moyen de canalisation 3, 300 est situé immédiatement en face ou à l'endroit d'une sortie 34 de la machine où le liquide d'infusion est apporté vers le moyen de canalisation 3, 300The pod 1 being favorably provided for use on a beverage preparation machine, it is recommended that this pod 1 comprises a fastening element 24 adapted to be removably connected to complementary means 25 of a preparation machine 50 of drink. As can be seen on the Figures 18 and 19 once the pod 1 thus fixed to the machine 50, the opening 4 of the channeling means 3, 300 is located immediately opposite or at the location of an outlet 34 of the machine where the infusion liquid is brought to channeling means 3, 300

Les figures 17 à 19 schématisent le cas différent d'un ensemble 60 comprenant une dosette 1 pour la préparation de boisson infusée, une machine 50, et au moins un moyen de canalisation 3, 300 s'étendant à l'intérieur du volume de l'enveloppe 2 pour y acheminer le liquide, dans un état fonctionnel, le moyen de canalisation 3, 300 présentant au moins un passage 6 pour faire passer le liquide vers la substance 1a à infuser. La plus grande partie de ce qui précède est applicable à ce cas de figure.The Figures 17 to 19 schematize the different case of a set 60 comprising a pod 1 for the preparation of brewed beverage, a machine 50, and at least one channeling means 3, 300 extending inside the volume of the envelope 2 to delivering the liquid, in a functional state, the channeling means 3, 300 having at least one passage 6 to pass the liquid to the substance 1a to be infused. Most of the above is applicable to this case.

Dans cet ensemble 60, la dosette 1 comprend une enveloppe souple 2 qui entoure un volume 2a contenant une substance 1a à infuser.In this set 60, the pod 1 comprises a flexible envelope 2 which surrounds a volume 2a containing a substance 1a to be infused.

Plus précisément, la machine 50 comprend un moyen de canalisation 300 et la dosette 1 comprend un accès pour le recevoir. La dosette 1 comporte cependant également un orifice 30 pour recevoir le moyen de canalisation 300, qui est ainsi prévu sur la machine 50. Le moyen de canalisation 300 peut être formé en un tube 100 comme vu précédemment. L'orifice 30 peut être formé par la bordure 29 de la paroi 15 de l'enveloppe 2. Dans ce cas la bordure 29 peut comporter un ourlet 31 dans lequel un élément de serrage 32, tel un élastique ou un joint est ménagé de sorte que la dosette 1 soit montée de manière ajustée autour de la paroi 5 du moyen de canalisation 300 (voir figure 16). Dans une variante illustrée figure 15, l'orifice 30 peut être prévu (agencé) dans la structure intermédiaire 11. On peut prévoir que le moyen de canalisation 300 perce la structure 11. Le moyen de canalisation 300 peut également écarter ou percer les mailles de la paroi 15 de l'enveloppe 2.More specifically, the machine 50 comprises a channeling means 300 and the pod 1 comprises an access to receive it. The pod 1, however, also has an orifice 30 for receiving the channeling means 300, which is thus provided on the machine 50. The channeling means 300 may be formed into a tube 100 as previously seen. The orifice 30 may be formed by the rim 29 of the wall 15 of the envelope 2. In this case the rim 29 may comprise a hem 31 in which a clamping element 32, such as an elastic or a gasket, is provided. that the pod 1 is fitly mounted around the wall 5 of the channeling means 300 (see FIG. figure 16 ). In an illustrated variant figure 15 , the orifice 30 may be provided (arranged) in the intermediate structure 11. It can be provided that the channeling means 300 pierces the structure 11. The channeling means 300 can also separate or drill the meshes of the wall 15 of the envelope 2.

Dans une autre variante illustrée sur les figures 13 et 14, l'orifice 30 peut être formé en partie supérieure d'une poche 12 souple, laquelle s'étend à l'intérieur de l'enveloppe 2. Cette poche 12 comporte une cavité 13 interne adaptée à recevoir de manière ajustée également le moyen de canalisation.In another variant illustrated on the Figures 13 and 14 , the orifice 30 may be formed in the upper part of a flexible pouch 12, which extends inside the casing 2. This pouch 12 has an internal cavity 13 adapted to receive equally well the means of pipe.

De la sorte, le moyen de canalisation 300 prévu sur la machine 50 sera reçu dans l'orifice 30 de la dosette 1 pour s'étendre à l'intérieur du volume de l'enveloppe 2 pour amener le liquide vers la substance 1a à infuser. La substance à infuser est disposée en partie en-dessous du moyen de canalisation, dans le prolongement de la direction d'allongement du moyen de canalisation.In this way, the channeling means 300 provided on the machine 50 will be received in the orifice 30 of the pod 1 to extend inside the volume of the casing 2 to bring the liquid to the substance 1a to infuse . The substance to be infused is placed partly below the channeling means, in the extension of the elongation direction of the channeling means.

Sur les figures 18 et 19, le moyen de canalisation 300 s'étend depuis une zone 33 de la machine 50. Le moyen de canalisation 300, tel le tube 100, est situé à l'endroit d'une sortie 34 de liquide où le liquide d'infusion est apporté vers ce moyen de canalisation 300.On the Figures 18 and 19 , the channeling means 300 extends from a zone 33 of the machine 50. The channeling means 300, such as the tube 100, is located at the location of an outlet 34 of liquid where the infusion liquid is brought towards this channeling means 300.

La machine 50 est une machine de préparation de boisson infusée, qui comprend de préférence, sur un circuit commun 50a et comme schématisé figure 17:

  • un réservoir d'eau 35 ;
  • une chaudière 36 qui peut contenir un ensemble radiateur-sonde de température, capteur de pression pour fournir de l'eau chaude ;
  • une pompe 37 interposée sur un conduit 38 reliant le réservoir 35 et la chaudière 36;
  • un clapet anti-retour 39 ;
  • une unité de pilotage du circuit 50a (unité de mémoire, microcontrôleur, etc.) ;
  • un conduit final 41 débouchant sur la sortie 34 du liquide chaud.
The machine 50 is a brewed beverage preparation machine, which preferably comprises, on a common circuit 50a and as schematized figure 17 :
  • a water tank 35;
  • a boiler 36 which may contain a radiator-temperature probe assembly, a pressure sensor for supplying hot water;
  • a pump 37 interposed on a conduit 38 connecting the reservoir 35 and the boiler 36;
  • a non-return valve 39;
  • a control unit of the circuit 50a (memory unit, microcontroller, etc.);
  • a final conduit 41 opening on the outlet 34 of the hot liquid.

Une tasse 42 ou similaire est disposée sur un plateau 43 et sous la dosette 1 liée à la machine 50 (sur la figure 17) pour la réception de la boisson préparée.A cup 42 or the like is disposed on a tray 43 and under the pod 1 linked to the machine 50 (on the figure 17 ) for the reception of the prepared drink.

Comme schématisé plus distinctement figures 16 et 17, la machine 50 comporte en outre ladite zone 33 de réception de la dosette 1 face à la sortie 34. Cette zone de réception 33 comporte les moyens complémentaires 25 coopérant avec des éléments de fixation 24 de la dosette 1.As schematized more distinctly Figures 16 and 17 , the machine 50 further comprises said zone 33 for receiving the pod 1 facing the exit 34. This receiving zone 33 comprises the complementary means 25 cooperating with fixing elements 24 of the pod 1.

Des ressorts 44 peuvent ainsi être prévus, présentant une extrémité fixée à la machine 50 et une autre extrémité est destinée à crocheter pour retenir de façon amovible :

  • des anneaux 45 que comporte la pièce intermédiaire 11, 11' de la dosette 1 ;
  • ou directement avec une maille de l'enveloppe 2.
Springs 44 may thus be provided, having one end attached to the machine 50 and another end is intended to hook to retain removably:
  • rings 45 that includes the intermediate piece 11, 11 'of the pod 1;
  • or directly with a mesh of the envelope 2.

Bien entendu, d'autres moyens de fixation amovible sont envisageables.Of course, other removable attachment means are possible.

L'ensemble 60, dosette 1, machine 50 et moyen de canalisation fonctionne de la sorte : Lorsque la dosette 1 est connectée à une machine 50 au moyen des éléments de fixation 24 coopérant avec les moyens complémentaires 25, du liquide chaud, ici provenant du réservoir 35 et apportée (par exemple sous pression, mais pas nécessairement), à l'intérieur de la dosette 1 via la sortie 34 et le moyen de canalisation 3, 300 lequel est fixé à la machine ou à la pièce intermédiaire 11, 11' ou à l'enveloppe 2. Le liquide est d'abord canalisé dans le moyen de canalisation 3, 300 avant de s'éjecter latéralement ou en biais, par rapport à la direction principale d'allongement de l'enveloppe et du moyen de canalisation, par l'intermédiaire des passages 6 vers la substance 1a à infuser se trouvant à l'intérieur du volume 2a de l'enveloppe 2. Au contact du flux, la substance 1a à infuser est agitée, brassée et enrobée d'eau, ce qui lui permet de s'expanser à l'intérieur du volume 2a fermé que forme alors la paroi 15. Le liquide apporté à l'intérieur du volume de l'enveloppe 2 traverse la paroi 15 de l'enveloppe 2 (quasi instantanément) pour obtenir l'infusion (qui peut durer de quelques dizaines de secondes à environ deux minutes) s'écoulant ainsi dans la tasse 42.The assembly 60, pod 1, machine 50 and channeling means operates in this way: When the pod 1 is connected to a machine 50 by means of the fastening elements 24 cooperating with the complementary means 25, hot liquid, here coming from the tank 35 and brought (for example under pressure, but not necessarily), inside the pod 1 via the outlet 34 and the channeling means 3, 300 which is fixed to the machine or to the intermediate piece 11, 11 ' or the casing 2. The liquid is first channeled in the channeling means 3, 300 before ejecting laterally or at an angle, relative to the main direction of elongation of the casing and the channeling means through the passages 6 to the substance 1a to be infused inside the volume 2a of the casing 2. In contact with the flow, the substance 1a to be infused is stirred, stirred and coated with water, which allows him to expand inside the 2a closed volume that then forms the wall 15. The liquid brought inside the volume of the casing 2 crosses the wall 15 of the casing 2 (almost instantaneously) to obtain the infusion (which can last from a few tens of seconds to about two minutes) thus flowing into the cup 42.
