Description

La présente invention concerne un emballage pour aliments, en particulier un emballage adapté pour la conservation des aliments, et prêt à l'emploi pour une cuisson par vapeur desdits aliments.The present invention relates to a food packaging, in particular packaging suitable for the preservation of food, and ready for use for steam cooking said foods.

Certains aliments, préparés ou non, sont vendus prêt à consommés en étant conditionnés dans des emballages individuels. Le consommateur ouvre l'emballage et prélève les aliments contenus dans ledit emballage pour les préparer.Some foods, prepared or not, are sold ready to consumed while being packaged in individual packages. The consumer opens the packaging and takes the food contained in said package to prepare them.

On peut prévoir des emballages adaptés pour une cuisson des aliments directement dans l'emballage. On peut par exemple prévoir un emballage comprenant un récipient et un film d'operculage, et qui une fois ouvert par retrait du film peut être disposé directement dans un four classique ou un four à micro-onde pour cuisson.Can be provided packaging adapted for cooking food directly in the package. For example, we can predict a package comprising a container and a lidding film, and once opened by withdrawal of the film can be arranged directly in a conventional oven or a microwave oven for cooking.

La cuisson des aliments par vapeur est une cuisson saine permettant une conservation de la richesse nutritive des aliments. Pour cuire des aliments par vapeur, on utilise généralement un autocuiseur. Ceci nécessite une manipulation des aliments pour les transvaser dans l'autocuiseur. Par ailleurs, cela nécessite de disposer d'un autocuiseur. En outre, ces autocuiseurs sont généralement constitués de nombreux éléments qu'il faut nettoyer après chaque usage pour assurer une hygiène satisfaisante. Ces manipulations et opérations ne s'accordent pas avec le souhait des consommateurs de disposer d'aliments prêts à la consommation ou prêts à la cuisson, notamment directement dans leur emballage.Steaming food is healthy cooking allowing a conservation of the nutritive richness of the food. For steaming foods, a pressure cooker is usually used. This requires handling of food to transfer them to the pressure cooker. Moreover, this requires having a pressure cooker. In addition, these pressure cookers generally consist of many items that must be cleaned after each use to ensure satisfactory hygiene. These manipulations and operations do not agree not with the wish of consumers to have ready-to-eat foods consumption or ready for cooking, especially directly in their packaging.

Un but de la présente invention est d'obtenir un emballage de conditionnement d'aliments qui puisse être utilisé directement pour effectuer une cuisson à la vapeur des aliments qu'il contient.An object of the present invention is to obtain a packaging of food packaging that can be used directly for Steam the food it contains.

Un tel emballage pour aliments, destiné à une cuisson vapeur, comprend un récipient destiné à recevoir les aliments et muni d'une ouverture supérieure permettant l'accès aux aliments, et des premiers moyens de fermeture amovibles de ladite ouverture supérieure. Une paroi du récipient comprend au moins une zone percée munie de trous adaptés pour empêcher le passage d'aliments tout en permettant le passage de vapeur d'eau, l'emballage comprenant en outre des seconds moyens de fermeture amovibles aptes à obturer les trous, les seconds moyens de fermeture étant accessibles depuis l'extérieur.Such a food packaging, intended for steam cooking, includes a receptacle for receiving food and having a upper opening allowing access to food, and first removable closure means of said upper opening. A container wall includes at least one pierced area with holes adapted to prevent the passage of food while allowing the passage of water vapor, the packaging further comprising second removable closing means capable of closing the holes, the second closure means being accessible from the outside.

L'intérieur du récipient de l'emballage reste isolé du milieu extérieur tant que les premier et second moyens de fermeture obturent l'ouverture supérieure et les trous de la zone percée. Une atmosphère contrôlée peut être maintenue dans le récipient pour assurer la conservation des aliments. L'emballage peut être exposé dans un étalage sans risque de contamination par le milieu extérieur.The inside of the packaging container remains isolated from the middle outside as long as the first and second closure means close the upper opening and the holes in the pierced area. An atmosphere controlled can be kept in the container to ensure food preservation. The packaging can be exposed in a display without risk of contamination by the external environment.

Pour cuire les aliments à la vapeur directement dans l'emballage, il suffit à un utilisateur de retirer les seconds moyens de fermeture, libérant ainsi les trous, et de placer l'emballage au-dessus d'une source de vapeur d'eau, telle qu'une masse d'eau en ébullition, par exemple dans une casserole. Les seconds moyens de fermeture accessible depuis l'extérieur peuvent être retirés tout en maintenant les premiers moyens de fermeture fermé. La vapeur produite par la source de vapeur pourra pénétrer dans le récipient par les trous, la vapeur ne s'échappant pas par l'ouverture supérieure qui reste fermée. Ainsi, les aliments contenus dans le récipient sont maintenus dans une atmosphère saturée de vapeur et cuisent « à la vapeur ». Les aliments peuvent être conditionnés dans l'emballage en étant crus ou précuits.To steam food directly in packaging, it is sufficient for a user to withdraw the second means of closing, thus releasing the holes, and placing the package on top a source of water vapor, such as a mass of boiling water, for example in a saucepan. The second closing means accessible from the outside can be removed while maintaining the first closed closing means. The steam produced by source of steam may enter the container through the holes, the vapor not escaping through the upper opening which remains closed. Thus, the food contained in the container is maintained in a atmosphere saturated with steam and cook "steamed". Food may be packaged in the package by being raw or precooked.

Pour consommer les aliments cuits, l'utilisateur retire les premiers moyens de fermeture, libérant l'ouverture supérieure.To consume the cooked food, the user removes the first closing means, releasing the upper opening.

Dans un mode de réalisation, le récipient est délimité par une paroi périphérique et une paroi de fond percée.In one embodiment, the container is delimited by a peripheral wall and a pierced bottom wall.

Dans un mode de réalisation, l'emballage comprend une jupe en saillie à l'extérieur du récipient et entourant la zone percée.In one embodiment, the package comprises a skirt protruding outside the container and surrounding the pierced area.

De préférence, la jupe présente une paroi pleine. Lorsque la jupe plonge dans une masse d'eau en ébullition, la jupe force le passage de la vapeur vers la zone percée et dans le récipient, ce qui améliore la cuisson, et permet une cuisson rapide par vapeur. Le récipient peut être posé sur la jupe dans un fond d'eau en ébullition. Les seconds moyens de fermeture peuvent obturer l'extrémité libre de la jupe, ce qui facilite l'accessibilité et le retrait desdits seconds moyens de fermeture.Preferably, the skirt has a solid wall. When the skirt plunges into a mass of boiling water, the skirt forces the passage of steam to the pierced area and into the container, which improves cooking, and allows fast steam cooking. The container can be placed on the skirt in a boiling water bottom. The second closing means can close the free end of the skirt, which facilitates the accessibility and removal of said seconds means of closure.

Avantageusement, des premiers et/ou des seconds moyens de fermeture sont prévus sous la forme simple d'un film d'operculage soudé ou collé.Advantageously, first and / or second means of closure are provided in the simple form of a lidding film welded or glued.

Avantageusement, l'emballage comprend au moins une poignée intégrée articulée entre une position rabattue contre le récipient et une position écartée. La poignée intégrée facilite la récupération de l'emballage une fois que les légumes sont cuits. La poignée articulée peut être maintenue écartée du récipient pendant une cuisson pour éviter qu'elle ne chauffe en même temps que le récipient. On peut prévoir des moyens pour retenir la poignée en position écartée du récipient pendant la cuisson.Advantageously, the package comprises at least a handful articulated between a folded position against the container and a discarded position. The built-in handle makes it easy to recover the package once the vegetables are cooked. The articulated handle can be kept away from the container during cooking for prevent it from heating up at the same time as the container. We can provide means for retaining the handle in the separated position of the container during cooking.

Dans un mode de réalisation, l'emballage comprend un rebord entourant l'ouverture supérieure et muni d'organes de préhension prédécoupés dans le rebord et articulés sur des éléments fixes du rebord par l'intermédiaire de charnières, de façon à pouvoir être amené en position dressée.In one embodiment, the package includes a rim surrounding the upper opening and provided with gripping members precut in the rim and articulated on fixed elements of the flange via hinges, so that it can be brought in erect position.

Dans un mode de réalisation, les organes de préhension comprennent des moyens de fixation aptes à coopérer mutuellement pour maintenir les organes en position dressée.In one embodiment, the gripping members comprise fixing means capable of mutually cooperating to keep the organs in an upright position.

Dans un mode de réalisation, les charnières sont formées par des zones amincies du rebord facilement déformables sans risque de rupture.In one embodiment, the hinges are formed by thinned areas of the rim easily deformable without risk of break.

L'anse 17, 18 est située dans le plan du rebord 9, et liée à ce dernier par des moyens de liaison temporaires formant une zone de moindre résistance, par exemple un ou plusieurs points de liaison répartis sur la ligne de découpe 19. Les anses 17, 18 sont munies de zones centrales 21, 22. Les anses 17 et 18 diffèrent en ce que la zone centrale 21 de l'anse 17, à gauche sur la figure 2, et munie sur un bord extérieur d'une découpe 23, la zone centrale 22 de l'autre anse 18, à droite sur la figure 2, étant muni symétriquement d'un crochet élastique d'encliquetage 24, apte à coopérer avec la découpe 23.An integrated handle 17, 18 is in the form of a handle with substantially semicircular profile whose ends are connected by hinges 20 of axis parallel to the plane of symmetry A and made here in the form of zones or thinned connections of the flange 9. A handle 17, 18 is formed by cutting while being separated from the flange by a cutting line 19 describing an arc. The handle 17, 18 is located in the plane of the rim 9, and linked to the latter by means of temporary links forming a zone of least resistance, for example example one or more points of connection distributed on the line of The handles 17, 18 are provided with central zones 21, 22. The handles 17 and 18 differ in that the central zone 21 of the handle 17, left in Figure 2, and provided on an outer edge of a blank 23, the central zone 22 of the other loop 18, on the right in FIG. being symmetrically provided with a resilient snap hook 24, adapted to cooperate with the cut 23.

    Les anses 17, 18 forment des organes de préhension prédécoupés dans le rebord 9, alignés avec le rebord 9 dans une position initiale rabattue et pouvant être articulés sur les liaisons minces 20 et amenées en position dressée où les zones centrales des anses 17, 18 sont écartées du récipient 1.The handles 17, 18 form gripping members precut in the flange 9, aligned with the flange 9 in a initial position folded and can be articulated on the links thin and brought into an upright position where the central zones of handles 17, 18 are separated from the container 1.

    Le fonctionnement de l'emballage est illustré par les figures 3 à 5, où les références numériques aux éléments semblables à ceux des figures 1 et 2 ont été conservées.The operation of the package is illustrated by FIGS. at 5, where numerical references to elements similar to those of Figures 1 and 2 have been preserved.

    Comme illustré sur la figure 3, lors du conditionnement, des aliments crus ou précuits sont disposés dans le récipient 1. Ensuite, l'emballage est fermé, de préférence sous atmosphère contrôlée, par exemple sous atmosphère pauvre en O2 et riche en CO2 pour éviter une oxydation des aliments et prolonger leur conservation en préservant leur aspect, en fermant les ouvertures supérieure 8 et inférieure 12 à l'aide des films d'operculage supérieur 13 et inférieur 14. Les films d'operculage peuvent être fixés respectivement sur le rebord 9 et sur le bord d'extrémité 11 par soudage, collage, ou tout autre moyen approprié.As illustrated in FIG. 3, during the packaging, raw or precooked foods are placed in the container 1. Then, the package is closed, preferably in a controlled atmosphere, for example in a low O 2 atmosphere and rich in CO 2 to prevent oxidation of the food and prolong their preservation by preserving their appearance, by closing the upper 8 and lower 12 openings with the upper lidding films 13 and lower 14. The lidding films can be respectively fixed on the flange 9 and on the end edge 11 by welding, gluing, or any other suitable means.

    La jupe 10 délimite un espace inférieur compris radialement à l'intérieure de la jupe et axialement entre la paroi de fond 6 du récipient 1 et le film d'operculage inférieur 14. Comme illustré sur la figure 3, cet espace peut avantageusement être utilisé pour disposer dans l'emballage des sachets 25 de sauces préparées ou de condiments à utiliser avec les aliments une fois ces derniers cuits.The skirt 10 delimits a lower space included radially to the inside of the skirt and axially between the bottom wall 6 of the container 1 and the lower lidding film 14. As illustrated in FIG. FIG. 3, this space can advantageously be used to dispose of in the packaging of prepared sauce sachets 25 or condiments to use with food once cooked.

    L'emballage, hermétiquement fermé par les films d'operculage 13, 14, peut aisément être transporté et disposé sur des étalages de vente, sans risque de contamination des aliments.The packaging, hermetically sealed by lidding films 13, 14, can easily be transported and arranged on displays of sale, without risk of contamination of food.

    Pour préparer les aliments, un utilisateur commence par retirer les moyens de fermeture de la zone percée de la paroi du récipient, ici en retirant le film d'operculage inférieur 14. Si des sachets ont été introduits dans l'espace inférieur, l'utilisateur les retire.To prepare food, a user starts by removing the means for closing the pierced zone of the wall of the container, here by removing the lower lidding film 14. If pouches have been introduced into the lower space, the user removes them.

    Ensuite, et comme illustré sur la figure 4, l'utilisateur peut relever les poignées intégrées. Pour ce faire, l'utilisateur casse les points de fixation entre les anses 17, 18 et le rebord 9, sans percer le film d'operculage supérieur 13, et fait pivoter les anses 17, 18 vers le haut autour des charnières 20, par pliage de ces dernières, comme illustré par les flèches F1 et F2, de façon à rapprocher les zones centrales des anses 17, 18 jusqu'à amener les zones centrales en contact en encliquetant le crochet 24 d'une zone centrale 21 dans la découpe correspondante de l'autre zone centrale 22. Le crochet 24 retient les anses 17, 18 qui se maintiennent ainsi réciproquement en position dressée et son empêchées de retomber.Then, and as shown in Figure 4, the user can lift the integrated handles. To do this, the user breaks the fixing points between the handles 17, 18 and the flange 9, without piercing the upper lidding film 13, and rotates the handles 17, 18 towards the up around the hinges 20, by folding these, as illustrated by arrows F1 and F2, so that the zones centers of the handles 17, 18 to bring the central zones into contact by snapping the hook 24 of a central zone 21 in the corresponding cutout of the other central zone 22. The hook 24 holds the handles 17, 18 which thus remain mutually erect position and prevented him from falling back.

    On notera que le film d'operculage supérieur 13 est de préférence fixé sur le rebord 9 sans déborder sur les poignées intégrées 16.It will be noted that the upper lidding film 13 is of preferably fixed on the rim 9 without overflowing on the integrated handles 16.

    Ensuite, comme illustré sur la figure 5, après avoir porté un fond d'eau 27 à ébullition dans un ustensile de cuisine du type casserole, l'utilisateur dépose l'emballage dans la casserole en appui sur la jupe 10. Le fond d'eau 27 présente une hauteur inférieure à la hauteur de la jupe 10 de façon que la paroi de fond 6 se situe hors de l'eau et que les légumes soient maintenus hors de l'eau. La vapeur 28 produite par l'eau en ébullition située sous la jupe 10 est piégée sous la jupe 10 et monte par les trous 7 de la paroi de fond 6 dans le récipient 1, comme illustré par les flèches F3. La vapeur est empêchée de sortir par le film d'operculage supérieur 13. Les aliments 26 contenus dans le récipient 1 sont ainsi cuits à la vapeur.Then, as shown in Figure 5, after wearing a bottom of water 27 to boiling in a kitchen utensil of the type pan, the user places the packaging in the pan in support on the skirt 10. The bottom 27 has a height lower than the height of the skirt 10 so that the bottom wall 6 is out of water and keep the vegetables out of the water. The steam 28 produced by the boiling water located under the skirt 10 is trapped under the skirt 10 and goes up through the holes 7 of the bottom wall 6 in the container 1, as illustrated by the arrows F3. Steam is prevented to exit through the upper lidding film 13. Food 26 contained in the container 1 are thus steamed.

    Lorsque les aliments sont cuits, l'utilisateur peut récupérer l'emballage sans risque de brûlure en l'attrapant par les zones centrales des anses 17, 18, qui sont maintenues plus froides que le récipient 1 du fait de leur position éloignée du récipient 1. L'utilisateur peut ensuite retirer le film d'operculage supérieur 13, et récupéré les aliments.When the food is cooked, the user can recover the packaging without risk of burn by catching it by the zones centers of the handles 17, 18, which are kept colder than the container 1 because of their position remote from the container 1. The user can then remove the upper lidding film 13, and recovered the food.

    L'emballage peut être prévu en tout matériau approprié pour le conditionnement des aliments et susceptible de résister à une température d'environ 100°C sans polluer les aliments.The packaging may be provided in any material suitable for the food packaging and likely to withstand a temperature of about 100 ° C without polluting the food.

    Les trous prévus dans la paroi de fond peuvent posséder des formes variées, pourvu que leurs dimensions permettent le passage de la vapeur d'eau tout en retenant des aliments. Des trous sensiblement circulaires peuvent présenter un diamètre de 0,1 à 5 mm, notamment de 0,5 à 3 mm. The holes provided in the bottom wall may have varied forms, provided that their dimensions allow the passage of water vapor while retaining food. Holes substantially circles may have a diameter of 0.1 to 5 mm, in particular from 0.5 to 3 mm.

    Les charnières 20 prévues sous la forme de liaisons minces, sont plus étendues et donc plus résistantes que les points de fixation très ponctuels, ce qui évite leur rupture lorsque les points de fixation sont eux rompus. En outre, lors de leur déformation par pliage, les charnières 20 ne se rompent pas du fait de leur minceur. Les poignées intégrées prédécoupées sont simples et de coût de fabrication faible.The hinges 20 provided in the form of thin links, are larger and therefore more resistant than fixation points very punctual, which prevents their breakage when fixing points they are broken. In addition, during their deformation by folding, the hinges 20 do not break because of their thinness. Handles Pre-cut integrated systems are simple and of low manufacturing cost.

    Bien que dans les modes de réalisation illustré les moyens de fermeture soient prévus sous la forme de films d'operculage, on peut, bien entendu, prévoir d'autres moyens de fermeture amovibles.Although in the illustrated embodiments the means of closure are provided in the form of lidding films, it is possible, of course, provide other removable closure means.

    La jupe et le récipient peuvent être réalisé de façon monobloc, par exemple par moulage par injection. On peut aussi prévoir des éléments séparés fixés par encliquetage ou thermosoudage.The skirt and the container can be made in one piece, for example by injection molding. We can also provide separate elements fixed by snapping or heat sealing.

    Grâce à l'invention, on obtient un emballage pour aliment permettant une cuisson des aliments à la vapeur directement dans l'emballage, sans nécessiter d'équipement particulier, sans salir de nombreux ustensiles.Thanks to the invention, a packaging for food is obtained allowing cooking of steamed food directly in packaging, without the need for special equipment, without many utensils.
