  • Food packaging bags are known for storing foods and transforming them by placing them in contact with an exchange medium while said foods are inside the sachet.
  • Said exchange medium may for example consist of a hot cooking liquid.
  • cooking bags for example for cooking rice. These bags, pre-filled with rice, are generally pierced with multiple orifices, so as to allow the rice to come into contact with cooking water within the bag. This bag thus pre-filled can be immersed in a saucepan of boiling water by the user to cook or complete the cooking of the rice contained therein.
  • Bags in the form of cushions obtained for example by a vertical bagging method, are known in particular. These bags result from the folding and sealing on itself of a plastic sheet, said sheet thus forming a tube provided with a longitudinal weld line, said tube being closed at both ends by a first and a second line transverse heat sealing to form a closed pouch containing the food to be processed, for example rice to cook and hydrate.

  • the extraction operation of the bag out of the exchange medium can be difficult to achieve, given the flaccid nature of the bag.
  • the extraction of the bag out of boiling water is generally delicate and risky, since it implies that the user recovers in a hot environment a heavy and flexible object, so difficult to grasp.
  • the bags of the prior art In order to facilitate this extraction operation, it is known to provide the bags of the prior art with a " fork slot ".
  • the known bags comprise a third transverse heat-sealing line, disposed substantially parallel and at a distance from one of the other two transverse heat-sealing lines mentioned above, in order to define at one of the ends of the bag a transverse band. of matter.
  • the " fork slot " is in the form of a cut in the band of material described previously. The user is thus able, by introducing an elongated object, such as a fork, into the groove, to hook the bag in order to extract it from the exchange medium, for example boiling water. .
  • the opening of the bag is then obtained by tearing, said tear being generally facilitated by the presence of a priming notch.
  • the bag tends, because of its flaccid nature, to wrinkle and fold over itself, so that the user is no longer really able to distinguish the contours and the orientation of the bag .
  • the user must therefore proceed by trial and error with his fork, in search of the slot, which is also of relatively small size compared to that of the bag.
  • the fork slot must be positioned between two weld lines, which requires the realization of the third weld line mentioned above.
  • the realization of this third weld line therefore increases the cost and complexity of manufacture of the bag.
  • the user must identify the tear initiation notch, which is not always easy to distinguish, especially in the case of a bag obtained by a continuous process of vertical bagging, especially given many burrs of material extending from the bag.
  • a pouch as defined in the preamble of claim 1 is illustrated in the document EP-A-0 947 444 .

TECHNIQUE ANTERIEUREPRIOR ART

On connaît des sachets de conditionnement d'aliments destinés à stocker les aliments et à les transformer par mise en contact avec un milieu d'échange alors que lesdits aliments sont à l'intérieur du sachet.Food packaging bags are known for storing foods and transforming them by placing them in contact with an exchange medium while said foods are inside the sachet.

Ledit milieu d'échange peut par exemple consister en un liquide de cuisson chaud. On connaît ainsi des sachets de cuisson, destinés par exemple à la cuisson de riz. Ces sachets, pré-remplis de riz, sont généralement percés de multiples orifices, de façon à permettre la mise en contact du riz avec de l'eau de cuisson au sein du sachet. Ce sachet ainsi pré-rempli peut ainsi être plongé dans une casserole d'eau bouillante par l'utilisateur, afin de cuire ou d'achever la cuisson du riz qui y est contenu.Said exchange medium may for example consist of a hot cooking liquid. Thus known cooking bags, for example for cooking rice. These bags, pre-filled with rice, are generally pierced with multiple orifices, so as to allow the rice to come into contact with cooking water within the bag. This bag thus pre-filled can be immersed in a saucepan of boiling water by the user to cook or complete the cooking of the rice contained therein.

On connaît en particulier des sachets se présentant sous la forme de coussins, obtenus par exemple par un procédé d'ensachage vertical. Ces sachets résultent du repliement et du thermosoudage sur elle-même d'une feuille de matière plastique, ladite feuille formant ainsi un tube pourvu d'une ligne de soudure longitudinale, ledit tube étant fermé vers ses deux extrémités par une première et une deuxième lignes transversales de thermosoudage, afin de former une poche fermée contenant les aliments à transformer, par exemple du riz à cuire et à hydrater.Bags in the form of cushions, obtained for example by a vertical bagging method, are known in particular. These bags result from the folding and sealing on itself of a plastic sheet, said sheet thus forming a tube provided with a longitudinal weld line, said tube being closed at both ends by a first and a second line transverse heat sealing to form a closed pouch containing the food to be processed, for example rice to cook and hydrate.

Lorsque le cycle de transformation des aliments contenus dans le sachet est achevé, l'utilisateur extrait le sachet hors du milieu d'échange, puis le déchire afin d'en transvaser le contenu dans un récipient adéquat. Par exemple, dans le cas d'un sachet de cuisson de riz, l'utilisateur extrait le sachet hors de l'eau en fin de cycle de cuisson, l'égoutte, puis le déchire afin de transvaser le riz du sachet vers un plat de service.When the food processing cycle contained in the bag is completed, the user extracts the bag from the exchange medium, then tears it to transfer the contents into a suitable container. For example, in the case of a rice cooking bag, the user extracts the bag out of the water at the end of the cooking cycle, dries it, then tears it to transfer the rice from the bag to a dish on duty.

L'opération d'extraction du sachet hors du milieu d'échange peut être difficile à réaliser, compte-tenu du caractère flasque du sachet. En particulier, dans le cas d'un sachet de cuisson de riz, l'extraction du sachet hors de l'eau bouillante s'avère généralement délicate et risquée, puisqu'elle implique que l'utilisateur récupère au sein d'un milieu brûlant un objet lourd et souple, donc difficile à saisir.The extraction operation of the bag out of the exchange medium can be difficult to achieve, given the flaccid nature of the bag. In particular, in the case of a rice cooking bag, the extraction of the bag out of boiling water is generally delicate and risky, since it implies that the user recovers in a hot environment a heavy and flexible object, so difficult to grasp.

Afin de faciliter cette opération d'extraction, il est connu de pourvoir les sachets de l'art antérieur d'une « fente à fourchette ». Pour cela, les sachets connus comportent une troisième ligne transversale de thermosoudure, disposée sensiblement parallèlement et à distance de l'une des deux autres lignes transversales de thermosoudure évoquées précédemment, afin de délimiter au niveau de l'une des extrémités du sachet une bande transversale de matière. La « fente à fourchette » se présente sous la forme d'une entaille ménagée au sein de la bande de matière décrite précédemment. L'utilisateur est ainsi en mesure, en introduisant un objet allongé, tel qu'une fourchette, au sein de l'entaille, de crocheter le sachet en vue de l'extraire du milieu d'échange, par exemple de l'eau bouillante.In order to facilitate this extraction operation, it is known to provide the bags of the prior art with a " fork slot ". For this purpose, the known bags comprise a third transverse heat-sealing line, disposed substantially parallel and at a distance from one of the other two transverse heat-sealing lines mentioned above, in order to define at one of the ends of the bag a transverse band. of matter. The " fork slot " is in the form of a cut in the band of material described previously. The user is thus able, by introducing an elongated object, such as a fork, into the groove, to hook the bag in order to extract it from the exchange medium, for example boiling water. .

L'ouverture du sachet est ensuite obtenu par déchirure, ladite déchirure étant généralement facilitée par la présence d'une entaille d'amorçage.The opening of the bag is then obtained by tearing, said tear being generally facilitated by the presence of a priming notch.

Ces sachets connus, s'ils donnent généralement satisfaction, présentent cependant un certain nombre d'inconvénients.These known bags, if they generally give satisfaction, however, have a number of disadvantages.

En premier lieu, il s'avère souvent malaisé pour l'utilisateur d'arriver à identifier, alors que le sachet est plongé dans le milieu d'échange, la fente à fourchette. En effet, le sachet à tendance, du fait de son caractère flasque, à se froisser et à se replier sur lui-même, de sorte que l'utilisateur n'est plus véritablement à même de distinguer les contours et l'orientation du sachet.In the first place, it is often difficult for the user to identify, while the bag is immersed in the exchange medium, the slot. Indeed, the bag tends, because of its flaccid nature, to wrinkle and fold over itself, so that the user is no longer really able to distinguish the contours and the orientation of the bag .

Ce repérage visuel est d'autant plus difficile dans le cas d'un sachet de cuisson, en particulier de riz. En effet, l'agitation due à l'ébullition de l'eau de cuisson a tendance à accentuer les phénomènes de froissement et de repliement du sachet sur lui-même. De surcroît, l'eau de cuisson, initialement transparente, se trouble, car elle est chargée en fin de cuisson de particules blanchâtres provenant de la cuisson du riz.This visual identification is even more difficult in the case of a cooking bag, especially rice. Indeed, the stirring due to the boiling of the cooking water tends to accentuate the phenomenon of wrinkling and folding of the bag on itself. In addition, the cooking water, initially transparent, is cloudy because it is loaded at the end of cooking whitish particles from cooking rice.

L'utilisateur doit donc procéder par tâtonnements avec sa fourchette, à la recherche de la fente, laquelle est en outre de dimension relativement petite par rapport à celle du sachet.The user must therefore proceed by trial and error with his fork, in search of the slot, which is also of relatively small size compared to that of the bag.

Cette difficulté de manipulation conduit d'ailleurs parfois l'utilisateur à abandonner l'idée de se servir de la fente à fourchette et à extraire le sachet hors du milieu d'échange par un autre moyen, qui peut s'avérer hasardeux en matière de sécurité en particulier lorsque le milieu d'échange est un liquide brûlant.This difficulty in handling sometimes leads the user to abandon the idea of using the fork slot and extract the bag out of the exchange medium by another means, which can be hazardous. in terms of safety especially when the exchange medium is a hot liquid.

En outre, pour des raisons de résistance mécanique, la fente à fourchette doit être positionnée entre deux lignes de soudure, ce qui impose la réalisation de la troisième ligne de soudure évoquée précédemment. La réalisation de cette troisième ligne de soudure augmente donc le coût et la complexité de fabrication du sachet.In addition, for reasons of mechanical strength, the fork slot must be positioned between two weld lines, which requires the realization of the third weld line mentioned above. The realization of this third weld line therefore increases the cost and complexity of manufacture of the bag.

De surcroît, une fois le sachet sorti hors du milieu d'échange, il s'avère généralement difficile de l'ouvrir rapidement, proprement, ainsi que sans risque de brûlure lorsque le milieu d'échange est un liquide de cuisson. En effet, l'utilisateur doit repérer l'entaille d'amorce de déchirure, qui n'est pas toujours facile à distinguer, en particulier dans le cas d'un sachet obtenu par un procédé continu d'ensachage vertical, compte-tenu notamment des nombreuses ébarbures de matière s'étendant à partir du sachet.In addition, once the bag out of the exchange medium, it is generally difficult to open quickly, cleanly, and without risk of burn when the exchange medium is a cooking liquid. Indeed, the user must identify the tear initiation notch, which is not always easy to distinguish, especially in the case of a bag obtained by a continuous process of vertical bagging, especially given many burrs of material extending from the bag.

Un sachet tel que défini dans le préambule de la revendication 1 est illustré dans le document EP-A-0 947 444 .A pouch as defined in the preamble of claim 1 is illustrated in the document EP-A-0 947 444 .

MEILLEURE MANIERE DE REALISER L'INVENTIONBEST MODE OF REALIZING THE INVENTION

Les figures 1 à 4 illustrent différents exemples de réalisation conformes à l'invention, d'un sachet 1 de conditionnement d'aliments destiné à être placé en contact avec un milieu d'échange pour transformer lesdits aliments.The Figures 1 to 4 illustrate various embodiments according to the invention of a food packaging bag 1 intended to be placed in contact with an exchange medium to transform said food.

Un tel sachet, qui est de préférence à usage unique (c'est-à-dire présente un caractère jetable), est destiné à contenir des aliments à transformer par contact direct de ces derniers avec le milieu d'échange, lequel présente de préférence un caractère fluide, et se trouve préférentiellement à l'état liquide.Such a bag, which is preferably disposable (that is to say has a disposable nature), is intended to contain food to be transformed by direct contact of the latter with the exchange medium, which preferably has a fluid character, and is preferably in the liquid state.

Ladite transformation peut s'opérer, selon la nature des aliments à transformer, avec ou sans apport d'énergie thermique.Said transformation can take place, depending on the nature of the food to be processed, with or without the addition of thermal energy.

Par « transformation », on désigne ici une modification physico-chimique des aliments visant à les rendre prêts à consommer, ou du moins à améliorer leurs propriétés organoleptiques et/ou leur aspect en vue de leur usage final.By " transformation " is meant here a physicochemical modification of food to make them ready to consume, or at least improve their organoleptic properties and / or their appearance for their end use.

Cette transformation s'opère lorsque les aliments sont en contact direct avec le milieu d'échange. Par exemple, dans le cas d'un milieu d'échange constitué d'un liquide, la transformation peut comprendre des phénomènes d'imbibition de liquide par les aliments, tels que des transferts osmotiques, ou encore des phénomènes de gélification par exemple.This transformation takes place when the food is in direct contact with the exchange medium. For example, in the case of an exchange medium consisting of a liquid, the transformation may include liquid imbibition phenomena by food, such as osmotic transfers, or even gelling phenomena for example.

Conformément à l'invention, le sachet de cuisson 1 comprend une poche fermée 2 destinée à contenir les aliments à transformer (non représentés).According to the invention, the cooking bag 1 comprises a closed bag 2 intended to contain the food to be processed (not shown).

Ladite poche 2 est perméable au milieu d'échange, de façon à autoriser un contact suffisant des aliments avec le milieu d'échange pour transformer lesdits aliments. En d'autres termes, la poche 2 est conçue de façon à laisser pénétrer en son sein une fraction suffisante du milieu d'échange pour initier les modifications physico-chimiques des aliments conduisant à la transformation de ces derniers. Ainsi, dans le cas d'aliments à hydrater, la poche 2 sera suffisamment perméable à l'eau pour permettre l'absorption d'eau, ou du moins de liquide, par les aliments.Said pocket 2 is permeable to the exchange medium, so as to allow sufficient contact of the food with the exchange medium to transform said food. In other words, the bag 2 is designed so as to allow a sufficient fraction of the exchange medium to enter therein to initiate the physico-chemical modifications of the food leading to the transformation of the latter. Thus, in the case of foods to hydrate, the bag 2 will be sufficiently permeable to water to allow the absorption of water, or at least liquid, by the food.

De façon préférentielle, l'invention concerne un sachet 1 dont la poche 2 est perméable aux liquides, et en particulier aux liquides dont la viscosité est proche ou similaire à celle de l'eau.Preferably, the invention relates to a bag 1 whose bag 2 is permeable to liquids, and in particular to liquids whose viscosity is close to or similar to that of water.

De façon encore plus préférentielle, le sachet 1 forme un sachet de cuisson destiné à contenir des aliments à cuire ou à réchauffer dans un liquide chaud, notamment des produits alimentaires particulaires, et en particulier des aliments à cuire et à réhydrater tels que du riz, des pâtes ou de la semoule.Even more preferably, the bag 1 forms a cooking bag intended to contain food to be cooked or heated in a liquid hot, particularly particulate food products, and in particular foods to be cooked and rehydrated such as rice, pasta or semolina.

Dans ce qui suit, pour des raisons de simplicité et de concision de description, on va décrire uniquement un sachet 1 de cuisson de riz, étant entendu que l'invention n'est absolument pas limitée à un sachet conçu pour ce type d'aliments, ni à un sachet destiné à subir un apport thermique.In what follows, for the sake of simplicity and conciseness of description, only a packet 1 of rice cooking will be described, it being understood that the invention is absolutely not limited to a bag designed for this type of food. nor to a bag intended to undergo a thermal contribution.

Le sachet de cuisson 1 est préférentiellement destiné à être pré-rempli desdits aliments à cuire, lesquels peuvent d'ailleurs avoir subi au préalable un début de cuisson.The cooking bag 1 is preferably intended to be pre-filled with said food to be cooked, which may also have previously undergone a beginning of cooking.

Le sachet de cuisson 1 assure ainsi une première fonction de stockage des aliments à cuire préalablement à leur cuisson.The cooking bag 1 thus provides a first storage function of the food to be cooked before cooking.

Le sachet de cuisson 1 assure également une deuxième fonction, puisqu'il est destiné à être plongé dans un liquide de cuisson, tel que de l'eau, en vue de réaliser la cuisson des aliments qu'il contient, constitués en l'occurrence de riz. Le sachet 1 assure ainsi un conditionnement de cuisson pour les aliments disposés en son sein.The cooking bag 1 also performs a second function, since it is intended to be immersed in a cooking liquid, such as water, in order to cook the food that it contains, constituted in this case rice. The sachet 1 thus ensures a cooking conditioning for the foods arranged within it.

La poche 2 se présente sous la forme d'une enveloppe, laquelle se présente elle-même par exemple sous la forme d'un matériau plastique, et définissant un volume interne fermé destiné à accueillir des aliments à cuire.The bag 2 is in the form of an envelope, which itself is for example in the form of a plastic material, and defining a closed internal volume for receiving food to cook.

Par volume interne fermé, on désigne ici un espace qui confine les aliments et les empêche de s'échapper hors de l'enveloppe, sans pour autant être étanche. Dans le cas de produits alimentaires à réhydrater, tels que du riz, des pâtes ou de la semoule, la poche 2 est formée d'une enveloppe perméable aux liquides. Ladite perméabilité peut être obtenue grâce à la nature même du matériau employé pour fabriquer l'enveloppe formant la poche 2, ou encore par le perçage de multiples orifices dans l'enveloppe formant la poche 2, lesdits orifices étant de taille suffisante pour laisser passer du liquide mais interdisant aux aliments contenus dans le sachet, en particulier lorsque ces derniers sont de nature particulaire, de s'échapper.Closed internal volume means here a space that confines food and prevents them from escaping out of the envelope, without being waterproof. In the case of food products to be rehydrated, such as rice, pasta or semolina, the bag 2 is formed of a liquid permeable envelope. Said permeability can be obtained thanks to the same nature of the material used to manufacture the envelope forming the pocket 2, or by the drilling of multiple orifices in the envelope forming the pocket 2, said orifices being of sufficient size to let liquid but prohibiting the food contained in the bag, especially when these are particulate, to escape.

Avantageusement, le sachet 1 conforme à l'invention présente une forme de coussin, ledit coussin étant délimité par quatre bords formant deux bords longitudinaux 2A, 2B sensiblement parallèles entre eux d'une part et deux bords transversaux 2C, 2D sensiblement parallèles entre eux d'autre part.Advantageously, the bag 1 according to the invention has a cushion shape, said cushion being delimited by four edges forming two longitudinal edges 2A, 2B substantially parallel to each other on the one hand and two transverse edges 2C, 2D substantially parallel to each other. 'somewhere else.

De façon préférentielle, la poche 2 est formée d'un film souple replié et soudé longitudinalement sur lui-même selon une ligne de soudure longitudinale 3, de sorte que ledit film forme un tube s'étendant longitudinalement entre une première et une deuxième zones terminales 4, 5. Ledit tube est fermé vers chacune de ces deux zones terminales 4, 5 par une ou plusieurs lignes de soudure transversales, de façon à former un volume fermé.Preferably, the pocket 2 is formed of a flexible film folded and welded longitudinally on itself along a longitudinal weld line 3, so that said film forms a tube extending longitudinally between a first and a second terminal zone 4, 5. Said tube is closed towards each of these two end zones 4, 5 by one or more transverse weld lines, so as to form a closed volume.

Les bords transversaux 2C, 2D sont ainsi formés par des bandes de scellage 20C, 20D.The transverse edges 2C, 2D are thus formed by sealing strips 20C, 20D.

Une telle construction est classique, et peut être notamment obtenue par un procédé d'ensachage vertical, qui est un procédé continu de fabrication de sachets pré-remplis. Un tel procédé est bien connu de l'homme du métier, et ne sera donc pas explicité plus avant dans ce qui suit. On notera qu'il est tout à fait envisageable de mettre en oeuvre, dans le cadre de l'invention, un autre procédé de fabrication, et par exemple un procédé d'ensachage discontinu, ou encore un procédé d'ensachage horizontal. La poche 2 peut également être préformée.Such a construction is conventional, and can be obtained in particular by a vertical bagging process, which is a continuous process for manufacturing pre-filled bags. Such a method is well known to those skilled in the art, and will not be explained further in what follows. Note that it is quite possible to implement, within the context of the invention, another manufacturing process, and for example a batch bagging process, or a horizontal bagging process. The pocket 2 can also be preformed.

Conformément à l'invention, le sachet de cuisson 1 comprend une anse de préhension 6 destinée à permettre la manipulation du sachet 1 par l'utilisateur final. En particulier, l'anse de préhension 6 est destinée à permettre à l'utilisateur d'extraire le sachet de cuisson 1 hors du bain de cuisson (constitué par exemple par de l'eau bouillante), lorsque le cycle de cuisson est achevé. L'anse de préhension 6 est donc conçue pour supporter l'ensemble du poids du sachet rempli d'aliments à cuire en fin de cuisson, c'est-à-dire lorsque lesdits aliments sont imbibés d'eau.According to the invention, the cooking bag 1 comprises a gripping loop 6 intended to allow the handling of the bag 1 by the end user. In particular, the handle 6 is intended to allow the user to extract the cooking bag 1 out of the cooking bath (consisting for example of boiling water), when the cooking cycle is completed. The gripping handle 6 is designed to support the entire weight of the bag filled with food to cook at the end of cooking, that is to say when said food is soaked with water.

L'anse de préhension 6 est préférentiellement conçue pour coopérer avec un ustensile de cuisine 13, telle qu'une fourchette 13A, une cuillère ou équivalent, ledit instrument de cuisine faisant office de gaffe d'accrochage pour saisir et extraire le sachet 1 hors de l'eau.The gripping handle 6 is preferably designed to cooperate with a kitchen utensil 13, such as a fork 13A, a spoon or the like, said kitchen instrument acting hooking hook for gripping and extracting the bag 1 out of the water.

Conformément à l'invention, la poche 2 est également pourvue d'une patte d'ouverture 7 associée à un moyen d'amorçage d'ouverture 8, ladite patte 7 étant susceptible d'être saisie manuellement par l'utilisateur et coopérant avec le moyen d'amorçage 7 pour que le tirage de la patte 7 provoque l'ouverture de la poche 2. Une telle association d'une patte d'ouverture 7 et d'un moyen d'amorçage 8 est bien connue en soi. Elle met en oeuvre une languette formant patte 7 destinée à être saisie entre les doigts de l'utilisateur puis à subir un effort de traction, du genre effort de pelage, qui va être communiqué à une zone d'amorçage 8, à partir de laquelle va s'opérer le déchirage de la poche 2, permettant ainsi la libération des aliments qui y sont contenus.According to the invention, the bag 2 is also provided with an opening tab 7 associated with an opening priming means 8, said tab 7 being capable of being manually grasped by the user and cooperating with the priming means 7 so that the pull of the tab 7 causes the opening of the pocket 2. Such a combination of an opening tab 7 and a priming means 8 is well known per se. It implements a tongue forming tab 7 to be grasped between the fingers of the user and then to undergo a tensile force of the kind of peeling force, which will be communicated to a priming zone 8, from which will tear the bag 2, allowing the release of food contained therein.

A cette fin, la poche 2 est réalisée de préférence à base d'un matériau déchirable après amorce, c'est-à-dire un matériau suffisamment résistant pour ne pas se déchirer lors de la manipulation normale du sachet, mais pouvant être facilement déchiré de manière volontaire par l'utilisateur à partir d'un point faible tel qu'une amorce.To this end, the bag 2 is preferably made from a tearable material after primer, that is to say a material strong enough not to tear during normal handling of the bag, but can be easily torn voluntarily by the user from a weak point such as a primer.

De manière avantageuse, le moyen d'amorçage d'ouverture 8 comprend au moins une entaille 9, 10 permettant d'amorcer une déchirure de la poche 2.Advantageously, the opening priming means 8 comprises at least one notch 9, 10 for initiating a tear in the pocket 2.

De façon préférentielle et connue en soi, ladite au moins une entaille 9, 10 est positionnée de façon adjacente à la patte 7, de telle sorte qu'un mouvement d'arrachement ou de pelage pratiqué sur la patte 7 engendre le prolongement, par déchirure, de l'entaille 9, 10 dans le matériau formant la poche 2.Preferably and known per se, said at least one notch 9, 10 is positioned adjacent to the tab 7, so that a tearing or peeling movement on the tab 7 causes the extension, by tearing , notch 9, 10 in the material forming the pocket 2.

De manière préférentielle, afin de maîtriser l'ouverture de la poche 2, c'est-à-dire la direction de déchirement de ladite poche 2, cette dernière est formée d'un matériau plastique mono-orienté, tel que cela est bien connu dans l'art antérieur.Preferably, in order to control the opening of the pocket 2, that is to say the tearing direction of said pocket 2, the latter is formed of a single-oriented plastic material, as is well known in the prior art.

A titre d'exemple, la poche 2 pourra être formée de polyéthylène haute densité, de propylène ou encore de polyester, cette liste n'étant bien sûr nullement limitative.For example, the bag 2 may be formed of high density polyethylene, propylene or polyester, this list is of course not limiting.

Afin de faciliter la maîtrise de déchirement de la poche 2, on pourra également éventuellement prévoir, tel que cela est illustré à la figure 4, une ligne d'affaiblissement 11, s'étendant dans la continuité de l'entaille 9. Ladite ligne d'affaiblissement est formée par exemple de prédécoupes rectilignes espacées mutuellement. Par exemple, dans le cas d'une poche 2 réalisée à partir d'un complexe multicouches, la ligne d'affaiblissement 11 peut être obtenue par une pré-découpe au laser d'une ou plusieurs couches superficielles du complexe. On pourra cependant mettre en oeuvre tout autre moyen d'affaiblissement local de la tenue mécanique de la poche 2 dans la continuité de l'entaille 9, sans pour autant sortir du cadre de l'invention.In order to facilitate the control of tearing of the bag 2, it will also be possible to optionally provide, as illustrated in FIG. figure 4 a weakening line 11 extending in the continuity of the notch 9. Said weakening line is formed for example of rectilinear pre-cuts spaced apart. For example, in the case of a pocket 2 made from a multilayer complex, the weakening line 11 can be obtained by laser pre-cutting of one or more surface layers of the complex. However, it will be possible to implement any other means of local weakening of the mechanical strength of the pocket 2 in the continuity of the notch 9, without departing from the scope of the invention.

Conformément à une caractéristique importante de l'invention, l'anse de préhension 6 comprend un cordon 12, c'est-à-dire un élément longiligne et flasque, tel qu'un ruban, une cordelette, un fil, une ficelle ou une tresse. De façon préférentielle, le cordon 12 est formé d'un ruban, c'est-à-dire d'une bande sensiblement plate, étroite et souple, s'étendant préférentiellement selon une seule direction de l'espace.According to an important characteristic of the invention, the handle 6 comprises a bead 12, that is to say an elongated and flanged element, such as a ribbon, a cord, a wire, a string or a string. braided. Preferably, the bead 12 is formed of a ribbon, that is to say a substantially flat, narrow and flexible band, preferably extending in a single direction of space.

Ledit cordon 12 s'étend entre d'une part une première extrémité 12A, vers laquelle le cordon 12 est solidarisé au niveau de la patte d'ouverture 7, et d'autre part une deuxième extrémité 12B, vers laquelle le cordon 12 est solidarisé à la poche 2, de préférence en une zone de la poche distante de la patte 7. Le cordon 12 est bien entendu positionné à l'extérieur du volume interne délimité par la poche 2.Said cord 12 extends between firstly a first end 12A, to which the cord 12 is secured at the opening tab 7, and secondly a second end 12B, to which the cord 12 is secured to the pocket 2, preferably in an area of the pocket remote from the tab 7. The cord 12 is of course positioned outside the internal volume defined by the pocket 2.

De préférence, le cordon 12 est solidarisé de manière localisée uniquement vers ces première et deuxième extrémités 12A, 12B, le reste du cordon étant libre, afin d'assurer de manière optimale la fonction d'anse de préhension qui lui est dévolue.Preferably, the bead 12 is secured locally only towards these first and second ends 12A, 12B, the remainder of the bead being free, in order to optimally ensure the gripping handle function devolved upon it.

De façon préférentielle, le cordon 12 est distinct de la poche 2, c'est-à-dire qu'il est rapporté sur cette dernière par un moyen de fixation approprié, par exemple par collage ou thermosoudage. Il est cependant tout à fait envisageable que le cordon vienne de matière avec la poche 2, sans pour autant que l'on sorte du cadre de l'invention.Preferably, the cord 12 is distinct from the bag 2, that is to say that it is attached to the latter by a suitable fastening means, for example by gluing or heat sealing. However, it is quite possible that the cord comes from material with the bag 2, without departing from the scope of the invention.

Ainsi, contrairement aux sachets de l'art antérieur, qui mettaient en oeuvre, en tant qu'anse de préhension, une fente ménagée dans l'un des bords transversaux 2C, 2D de la poche 2, la mise en oeuvre d'un cordon 12 conformément à l'invention permet de bénéficier d'une grande longueur de préhension, puisque la longueur du cordon 12 est indépendante de la dimension des bords 2C, 2D de la poche 2.Thus, unlike the bags of the prior art, which used, as a gripper, a slot formed in one of the transverse edges 2C, 2D of the bag 2, the implementation of a cord 12 according to the invention allows to benefit from a large length of grip, since the length of the bead 12 is independent of the dimension of the edges 2C, 2D of the pocket 2.

De même, la résistance mécanique du cordon 12 est indépendante de la résistance mécanique des bords transversaux 2C, 2D et longitudinaux 2A, 2B de la poche 2, ce qui n'est pas le cas lorsque l'anse de préhension est formée par une fente ménagée justement dans l'un des bords en question.Similarly, the mechanical strength of the bead 12 is independent of the mechanical strength of the transverse edges 2C, 2D and longitudinal 2A, 2B of the bag 2, which is not the case when the handle is formed by a slot arranged precisely in one of the edges in question.

De manière générale, le cordon 12 sera fabriqué à partir d'un matériau suffisamment résistant pour supporter le poids total du sachet rempli d'aliments éventuellement imbibés de liquide. Le cordon 12 pourra par exemple être réalisé en matière plastique, tel que du polyéthylène haute densité, du polypropylène, ou encore sous forme d'un complexe avec des couches de polypropylène ou de polyéthylène haute densité.In general, the cord 12 will be made from a material sufficiently strong to support the total weight of the bag filled with food possibly soaked in liquid. The cord 12 may for example be made of plastic, such as high density polyethylene, polypropylene, or in the form of a complex with layers of polypropylene or high density polyethylene.

Grâce au positionnement spécifique du cordon 12 mis en oeuvre dans le cadre de l'invention, l'ouverture de la poche 2 est facilitée. En effet, étant donné que la première extrémité 12A du cordon 12 est fixée à la patte 7, la localisation de ladite patte 7 est rendue très facile pour l'utilisateur, une fois qu'il a saisi le cordon 12. Cela provient notamment du fait que la traction exercée sur le cordon 12 (par exemple par la fourchette 13A) lors du soulèvement du sachet hors du liquide de cuisson induit une flexion de la patte 7, flexion qui donne à la patte 7 une orientation différente de celle du reste de la poche à partir de laquelle elle est issue.Thanks to the specific positioning of the cord 12 used in the context of the invention, the opening of the bag 2 is facilitated. Indeed, since the first end 12A of the cord 12 is fixed to the tab 7, the location of said tab 7 is made very easy for the user, once he has grasped the cord 12. This comes in particular from that the traction exerted on the bead 12 (for example by the fork 13A) during the lifting of the bag out of the cooking liquid induces a flexion of the tab 7, bending which gives the tab 7 a different orientation from that of the rest of the pocket from which it comes.

L'utilisateur peut ainsi facilement attraper le sachet grâce au cordon 12, puis dans le même temps facilement localiser la patte d'ouverture grâce à la solidarisation de ce cordon au niveau de, et de préférence sur, ladite patte d'ouverture 7.The user can thus easily catch the bag thanks to the cord 12, then at the same time easily locate the opening tab by the joining of this cord at, and preferably on, said opening tab 7.

La combinaison d'un cordon 12 d'une part, et de la fixation de ce cordon 12 vers la patte 7 d'autre part permet ainsi d'obtenir un sachet d'utilisation facile et sûre.The combination of a cord 12 on the one hand, and the attachment of this cord 12 to the tab 7 on the other hand thus provides a bag easy and safe use.

Avantageusement, le cordon 12 s'étend sensiblement dans la même direction que l'entaille 9, 10. En d'autres termes, le cordon 12 s'étend de préférence de façon sensiblement rectiligne parallèlement à l'entaille 9, 10. Cette similitude de direction entre l'entaille 9, 10 et le cordon 12 autorise une utilisation facilitée du sachet 1 conforme à l'invention. En effet, ce positionnement particulier du cordon 12 permet, lors de la préhension du sachet par un ustensile du genre fourchette 13A, d'exercer un effort de flexion autour de la direction transversale sur la patte 7, effort de flexion qui contribue à différencier clairement la patte 7 du reste du sachet 1.Advantageously, the bead 12 extends substantially in the same direction as the notch 9, 10. In other words, the bead 12 preferably extends substantially rectilinearly parallel to the notch 9, 10. direction between the notch 9, 10 and the cord 12 allows easy use of the bag 1 according to the invention. Indeed, this particular positioning of the cord 12 allows, during the gripping of the bag by a utensil of the fork kind 13A, to exert a bending force around the transverse direction on the leg 7, bending force which contributes to clearly differentiate the tab 7 of the rest of the bag 1.

Avantageusement, la patte 7 s'étend de manière sensiblement parallèle aux bords longitudinaux 2A, 2B, à partir de l'un des bords transversaux 2C.Advantageously, the tab 7 extends substantially parallel to the longitudinal edges 2A, 2B, from one of the transverse edges 2C.

La patte 7 est ainsi préférentiellement ménagée dans l'une des bandes de scellage 20C formant bord transversal 2C, par découpe de la patte 7 directement dans la bande de scellage 20C en question.The tab 7 is thus preferably formed in one of the sealing strips 20C forming a transverse edge 2C, by cutting the tab 7 directly into the sealing strip 20C in question.

Selon les variantes de réalisation correspondant aux figures 1, 2 et 4, la poche 2 présente un coin 14 au voisinage duquel est pratiquée l'entaille 9, la portion de poche s'étendant transversalement entre l'entaille 9 et le coin 14 formant la patte d'ouverture 7. L'entaille 9 s'étend ainsi longitudinalement dans la bande de scellage 20C, et débouche à l'extérieur du sachet 1.According to the variants corresponding to the Figures 1, 2 and 4 , the pocket 2 has a wedge 14 in the vicinity of which is made the notch 9, the pocket portion extending transversely between the notch 9 and the wedge 14 forming the opening tab 7. The notch 9 extends thus longitudinally in the sealing strip 20C, and opens out of the bag 1.

Dans une autre variante de réalisation, représentée à la figure 3, le moyen d'amorçage d'ouverture 8 comprend deux entailles 9, 10 s'étendant sensiblement parallèlement et à distance l'une de l'autre, la portion de poche s'étendant entre les deux entailles 9, 10 formant la patte d'ouverture 7. Dans cette variante, il n'est ainsi pas nécessaire de positionner le moyen d'amorçage d'ouverture 8 à proximité d'un coin, puisque les deux entailles 9, 10, ménagées longitudinalement dans la bande de scellage 20C, suffisent pour former la patte 7. Dans ce cas, la patte 7 peut ainsi être positionnée en n'importe quelle zone de la bande de scellage 4, et non exclusivement à proximité d'un bord longitudinal 2A, 2B.In another variant embodiment, represented in figure 3 , the opening priming means 8 comprises two notches 9, 10 extending substantially parallel and at a distance from each other, the pocket portion extending between the two notches 9, 10 forming the paw of 7. In this variant, it is thus not necessary to position the opening priming means 8 near a corner, since the two notches 9, 10, formed longitudinally in the sealing strip 20C, are sufficient to form the tab 7. In this case, the tab 7 can thus be positioned in any area of the sealing strip 4, and not exclusively near a longitudinal edge 2A, 2B.

Le cordon 12 s'étend de préférence sensiblement parallèlement aux bords longitudinaux 2A, 2B, sur sensiblement toute la longueur desdits bords 2A, 2B. Ainsi, contrairement aux sachets de l'art antérieur, l'utilisateur dispose d'une plage de préhension très importante, qui s'étend avantageusement sur toute la dimension longitudinale du sachet, parallèlement aux bords longitudinaux 2A, 2B.The bead 12 preferably extends substantially parallel to the longitudinal edges 2A, 2B, over substantially the entire length of said edges 2A, 2B. Thus, unlike the bags of the prior art, the user has a very large gripping range, which advantageously extends over the entire longitudinal dimension of the bag, parallel to the longitudinal edges 2A, 2B.

De façon avantageuse, le cordon 12 est formé d'un matériau dont l'aspect visuel diffère de l'aspect visuel du matériau à partir duquel est réalisée la poche 2. Grâce à cette mesure technique, l'utilisateur est à même de clairement identifier, de manière visuelle, le cordon 12, ce qui facilite la préhension du sachet 1 lorsque ce dernier se trouve immergé dans le liquide de cuisson.Advantageously, the cord 12 is formed of a material whose visual appearance differs from the visual appearance of the material from which the pocket 2 is made. Thanks to this technical measure, the user is able to clearly identify , visually, the cord 12, which facilitates the gripping of the bag 1 when the latter is immersed in the cooking liquid.

Par exemple, le cordon 12 pourra présenter une couleur différente de celle du reste du sachet. On peut par exemple envisager un sachet de couleur sensiblement blanchâtre et translucide, tandis que le cordon 12 est de couleur rouge.For example, the cord 12 may have a color different from that of the rest of the bag. For example, a pouch of a substantially whitish and translucent color may be envisaged, while the cord 12 is of a red color.

Grâce au fait que l'anse de préhension 6 est formée par un cordon 12 distinct des bandes de scellage 4, 5 (contrairement aux fentes à fourchette classiques), il est d'autant plus facile de différencier l'aspect visuel de l'anse 6 et de la poche 2.Due to the fact that the gripping loop 6 is formed by a bead 12 distinct from the sealing strips 4, 5 (unlike conventional forked slots), it is all the easier to differentiate the visual appearance of the handle 6 and pocket 2.

Dans ce qui précède, on a décrit des variantes dans lesquelles le moyen d'amorçage 8 comprend une ou plusieurs entailles 9, 10. Il est cependant tout à fait envisageable que le moyen d'amorçage 8 soit basé sur un autre principe technique, et par exemple sur la présence d'un élément de déchirure du genre « tear-cell ». Ces éléments bien connus permettent de déchirer une extrémité du sachet grâce à l'inclusion, au sein du matériau formant la poche 2, d'un fil ou d'une bande de déchirure.In the foregoing, variants have been described in which the initiating means 8 comprises one or more notches 9, 10. However, it is quite possible that the initiating means 8 is based on another technical principle, and for example on the presence of an element of tear-cell tearing. These well-known elements make it possible to tear an end of the bag thanks to the inclusion, within the material forming the pocket 2, of a wire or a tear strip.

L'invention concerne également un procédé de fabrication d'un sachet 1 de conditionnement d'aliments destiné à être placé en contact avec un milieu d'échange pour transformer lesdits aliments, ledit procédé comprenant :

  • une étape A de fabrication ou de fourniture d'une poche fermée 2 destinée à contenir lesdits aliments, ladite poche 2 étant perméable au milieu d'échange de façon à autoriser un contact suffisant des aliments avec le milieu d'échange pour transformer lesdits aliments,
  • une étape B de réalisation d'un moyen d'amorçage d'ouverture 8,
  • une étape C de réalisation d'une patte d'ouverture 7, au cours de laquelle on pourvoit ladite poche 2 d'une patte 7 susceptible d'être saisie manuellement par l'utilisateur, ladite patte 7 étant destinée à coopérer avec le moyen d'amorçage 8 pour que le tirage de la patte 7 provoque l'ouverture de la poche 2.
The invention also relates to a method of manufacturing a food packaging bag 1 intended to be placed in contact with an exchange medium for converting said foodstuffs, said method comprising:
  • a step A of manufacturing or supplying a closed bag 2 intended to contain said foodstuffs, said bag 2 being permeable to the exchange medium so as to allow sufficient contact of the food with the exchange medium to transform said food,
  • a step B of producing an opening priming means 8,
  • a step C of producing an opening tab 7, during which said pocket 2 is provided with a tab 7 that can be manually grasped by the user, said tab 7 being intended to cooperate with the means of priming 8 so that the pull of the tab 7 causes the opening of the bag 2.

De façon préférentielle, les étapes A, B et C sont réalisées de manière simultanée, tel que cela est d'ailleurs connu en tant que tel dans l'art antérieur.Preferably, steps A, B and C are performed simultaneously, as is moreover known as such in the prior art.

Selon une caractéristique importante du procédé conforme à l'invention, ledit procédé comprend une étape D de fixation d'un cordon 12 s'étendant entre une première et une deuxième extrémité 12A, 12B, étape D au cours de laquelle d'une part on fixe le cordon 12 vers sa première extrémité 12A au niveau de la patte d'ouverture 7, et d'autre part on fixe le cordon 12 vers sa deuxième extrémité 12B sur la poche 2.According to an important characteristic of the process according to the invention, said method comprises a step D of fixing a bead 12 extending between a first and a second end 12A, 12B, step D during which on the one hand fixed the cord 12 to its first end 12A at the opening tab 7, and secondly the cord 12 is fixed to its second end 12B on the bag 2.

Avantageusement, l'étape A comprend une sous-étape A' de formage, dans laquelle on replie et on soude longitudinalement sur lui-même, selon une ligne longitudinale de soudure 3, un film souple pour obtenir un tube. Ledit film souple est formé par exemple à partir d'une matière plastique translucide et thermoscellable, perméable à l'eau, tel que cela est bien connu dans le domaine.Advantageously, step A comprises a substep A 'of forming, in which is folded and welded longitudinally on itself, along a longitudinal weld line 3, a flexible film to obtain a tube. Said flexible film is formed for example from a translucent and heat-sealable plastic material, permeable to water, as is well known in the art.

De façon préférentielle, l'étape A comprend également une sous-étape A" de scellage, dans laquelle on ferme transversalement le tube obtenu à l'issue de l'étape A' selon une première et une deuxième bande de scellage 20C, 20D espacées l'une de l'autre, de façon à obtenir la poche fermée 2, laquelle présente alors une forme de coussin. Ce scellage peut être réalisé par tout moyen connu de l'homme du métier, et par exemple par la mise en oeuvre d'ultrasons, de rayonnements à hautes fréquences ou à infrarouges.Preferably, step A also comprises a sub-step A "of sealing, in which the tube obtained at the end of step A 'is transversely closed in a first and a second sealing strip 20C, 20D spaced apart. of the other, so as to obtain the closed pocket 2, which then has a cushion shape.This sealing can be achieved by any means known to those skilled in the art, and for example by the implementation of ultrasound, high-frequency radiation or infrared radiation.

Avantageusement, les étapes B et C sont confondus, la réalisation du moyen d'amorçage 8 engendrant simultanément la formation de la patte 7. Plus particulièrement, l'étape B peut comprend une sous-étape B' d'entaillage, dans laquelle on ménage dans la poche 2 au moins une entaille 8, 9 permettant d'amorcer une déchirure du sachet 2.Advantageously, the steps B and C are combined, the embodiment of the priming means 8 simultaneously generating the formation of the tab 7. More particularly, the step B may comprise a substep B 'of notching, in which one cleans in the pocket 2 at least one notch 8, 9 for initiating a tear of the bag 2.

De façon préférentielle, ladite au moins une entaille 8, 9 est ménagée dans l'une des bandes de scellage 20C, 20D et par exemple dans la première bande de scellage 20C.Preferably, said at least one notch 8, 9 is formed in one of the sealing strips 20C, 20D and for example in the first sealing strip 20C.

Avantageusement, au cours de l'étape D, le cordon 12 est fixé à la poche 2 au niveau de chacune des bandes de scellage 20C, 20D, de telle sorte que le cordon 12 s'étend avantageusement sensiblement parallèlement aux bords longitudinaux 2A, 2B.Advantageously, during step D, the cord 12 is fixed to the bag 2 at each of the sealing strips 20C, 20D, so that the cord 12 advantageously extends substantially parallel to the longitudinal edges 2A, 2B .

De manière préférentielle, les étapes A" et D sont simultanées, une opération unique de scellage, qui est par exemple une opération de thermosoudage, formant les bandes de scellage 20C, 20D et fixant simultanément le cordon 12.Preferably, the steps A "and D are simultaneous, a single sealing operation, which is for example a heat-sealing operation, forming the sealing strips 20C, 20D and simultaneously fixing the bead 12.

Le procédé conforme à l'invention est de préférence un procédé continu, et par exemple un procédé d'ensachage vertical continu.The process according to the invention is preferably a continuous process, and for example a continuous vertical bagging process.

Selon la méthode d'ensachage vertical, les sachets conformes à l'invention sont produits et remplis en continu, à partir d'un film de matière plastique souple déroulé d'une bobine. Ledit film est conformé sous forme tubulaire à l'aide d'un système du genre « col de cygne », bien connu de l'homme du métier, ladite bande étant thermoscellée et tronçonnée pour former les sachets individuels.According to the vertical bagging method, the bags according to the invention are produced and filled continuously, from a flexible plastic film unrolled from a reel. Said film is shaped in tubular form using a system of the type " gooseneck ", well known to those skilled in the art, said band being heat-sealed and cut to form the individual bags.

Un tel procédé permet d'obtenir, tout en conservant une cadence rapide, différentes formes de pattes d'ouverture 7.Such a method makes it possible to obtain, while maintaining a fast rate, different forms of opening tabs 7.

Ainsi, dans le cas de la variante représentée à la figure 1, la patte 7 présente une première portion de forme rectangulaire prolongée vers l'extérieur du sachet par une portion sensiblement en forme de quart de disque.Thus, in the case of the variant represented in figure 1 , the tab 7 has a first portion of rectangular shape extended towards the outside of the bag by a substantially quarter-shaped portion of disk.

Dans les variantes des figures 2 et 4, la patte 7 comprend une première portion de forme rectangulaire prolongée d'une deuxième portion de forme triangulaire.In the variants of figures 2 and 4 , the tab 7 comprises a first portion of extended rectangular shape of a second portion of triangular shape.

Quant à la variante de la figure 3, elle met en oeuvre une patte 7 présentant une tête arrondie.As for the variant of figure 3 it implements a lug 7 having a rounded head.

Compte-tenu du caractère continu du procédé de fabrication mis en oeuvre avantageusement dans le cadre de l'invention, le sachet 1 comprend, ménagé dans la deuxième bande de scellage 20D, une découpe 70 dont la forme est complémentaire à celle de l'extrémité de la patte 7.Given the continuous nature of the manufacturing method advantageously implemented in the context of the invention, the bag 1 comprises, formed in the second sealing strip 20D, a cutout 70 whose shape is complementary to that of the end of the tab 7.

On notera en dernier lieu que la mise en place du cordon 12 s'insère très facilement dans un procédé d'ensachage vertical de type connu. Il suffit en effet de dérouler, de manière synchrone avec le film plastique formant la poche 2, une bande de matière dans laquelle sera découpée le cordon 12.It will be noted lastly that the introduction of the cord 12 fits very easily in a vertical bagging process of known type. It suffices to unwind, synchronously with the plastic film forming the pocket 2, a strip of material in which the cord 12 will be cut.

En définitive, le procédé conforme à l'invention permet d'obtenir, de façon très simple et en s'appuyant sur des principes généraux bien connus, un sachet de cuisson 1, destiné en particulier à la cuisson de riz, présentant des avantages considérables en terme de facilité d'utilisation.Ultimately, the process according to the invention makes it possible to obtain, in a very simple manner and based on well-known general principles, a cooking bag 1, intended in particular for cooking rice, having considerable advantages. in terms of ease of use.

Dans ce qui précède, on a décrit, à titre d'exemple préférentiel, un sachet de cuisson de riz.In the foregoing, there is described, as a preferred example, a rice cooking bag.

L'invention peut cependant être appliquée également à une sauce culinaire épaisse (éventuellement avec des morceaux), se présentant initialement sous forme d'une composition déshydratée (en poudre ou formant une plaque monobloc) enfermée dans un sachet 1 conforme à l'invention. Lorsque le sachet 1 est plongé dans de l'eau chaude, la composition déshydratée se transforme en une sauce plus ou moins visqueuse qui peut être versée ensuite sur un plat à assaisonner ou à décorer.The invention may, however, also be applied to a thick culinary sauce (optionally with pieces), initially in the form of a dehydrated composition (in powder form or forming a monoblock plate) enclosed in a sachet 1 according to the invention. When the sachet 1 is immersed in hot water, the dehydrated composition is transformed into a more or less viscous sauce which can then be poured on a dish to be seasoned or decorated.

L'invention peut également être appliquée dans le domaine « sucré », par exemple pour la réalisation de couvertures ou nappages. Dans ce cas, lesdits nappages ou couvertures se présentent par exemple initialement sous forme sèche (déshydratée), enfermés dans un sachet 1. Au contact d'eau chaude ou froide, un phénomène du genre réhydratation et/ou gélification a lieu, qui conduit à l'obtention du produit sucré désiré, prêt à utiliser une fois sorti du sachet.The invention can also be applied in the " sweet " field, for example for producing blankets or toppings. In this case, said toppings or covers are for example initially in dry form (dehydrated), enclosed in a sachet 1. In contact with hot or cold water, a phenomenon of the rehydration and / or gelation type takes place, which leads to obtaining the desired sweet product, ready to use once out of the bag.
