Description

La présente invention concerne les récipients étanches au gaz, notamment de produits alimentaires ou d'autres produits destinés à subir un traitement thermique, de type "barquette".The present invention relates to gas-tight containers, in particular for food products or other products intended to undergo heat treatment, of the "tub" type.

Les plats cuisinés dans l'industrie alimentaire sont généralement conditionnés dans des emballages formés par des barquettes en feuille d'aluminium, en résine synthétique ou en complexe divers, tels que des cartons avec pelliculage de films.Dishes prepared in the food industry are generally packaged in packages formed by trays made of aluminum foil, synthetic resin or various complexes, such as cartons with film coating.

La cuisson des préparations culinaires a lieu avant leur introduction dans les barquettes. La fermeture de ces dernières est effectuée après la cuisson, ce qui provoque, en raison des transvasements, des risques de souillures et de contaminations.Cooking of culinary preparations takes place before their introduction into the trays. The latter are closed after cooking, which causes, due to transfers, the risk of soiling and contamination.

Au FR-A- 2 629 060, on décrit un dispositif d'obturation automatique pour le conditionnement pour préparations alimentaires à consommation différée par utilisation d'une part des effets de dilatation et d'échappement d'air chaud ou de vapeur lors des opérations de cuisson, et d'autre part de la contraction lors du refroidissement pour assurer par clapet anti-retour l'obturation hermétique du conditionnment en supprimant les pollutions et pertes d'arômes se produisant en cours d'opération de fermeture, se caractérisant par la combinaison d'une part d'une capacité formée par un double cloisonnement à la partie préférentiellement axiale d'un conditionnement avec perforations supérieures et inférieure et d'autre part par le positionnement d'un clapet anti-retour ou rondelle d'obturation dans l'espace intercalaire, étant précisé que ladite rondelle comporte des orifices périphériques et autres, et est placée librement pour effectuer un déplacement vertical de haut en bas et de bas en haut, soit pour libérer les orifices, soit pour les obturer avec guidage pour empêcher tout déplacement latéral pouvant perturber les évacuations et obturations.In FR-A- 2 629 060, an automatic closure device is described for packaging for food preparations with deferred consumption by using on the one hand the expansion and exhaust effects of hot air or steam during the operations. cooking, and on the other hand the contraction during cooling to ensure by non-return valve the hermetic sealing of the packaging by eliminating pollution and loss of aromas occurring during the closing operation, characterized by the combination on the one hand of a capacity formed by a double partitioning at the preferentially axial part of a package with upper and lower perforations and on the other hand by the positioning of a non-return valve or sealing washer in the intermediate space, it being specified that said washer has peripheral orifices and the like, and is placed freely to carry out a vertical displacement from top to bottom and bottom up, either to free the orifices, or to close them with guidance to prevent any lateral movement which could disturb the evacuations and obturations.

Ce dispositif est très compliqué à fabriquer. Dans la variante des figures 4, 5 et 6, on prévoit de le compliquer davantage, en appliquant un auto-collant, c'est-à-dire un support muni d'une couche de colle, tel qu'une étiquette, à la face inférieure des clapets antiretour pour éviter une ouverture accidentelle par chocs, déformations ou autres en cours de conservation. Cet auto-collant doit se diluer à chaud et n'adhérer qu'après refroidissement. Dans une autre variante des figures 7, 8 et 9, la barquette est operculée par un complexe de deux films contrecollés l'un à l'autre à l'exception de bandes longitudinales non enduites. Dans la variante des figures 10, 11 et 12, l'orifice supérieur d'un tube central est obturé ou libéré par un film de scellage qui agit comme une membrane. Dans une autre variante des figures 13, 14 et 15, un orifice ménagé sur le plat-rebord de la barquette forme le siège d'un clapet obturé par le film de scellage; on ne prévoit pas d'utiliser de substance fusible. La multiplicité de ces variantes, dont aucune ne s'est imposé en pratique, montre que l'on recherche toujours un moyen sur, mais simple, de permettre à l'air et à la vapeur d'eau contenus dans le récipient de s'échapper pendant la cuisson, lorsqu'il y a surpression, tout en empêchant l'air extérieur de pénétrer dans la barquette lors du refroidissement, lorsque la dépression se produit à l'intérieur, de sorte que les aliments ou autres soient pasteurisés ou stérilisés lors de la cuisson dans un emballage stérile, ce qui assure une conservation de plusieurs semaines, même sans surgélation ou autres moyens complémentaires tout en préservant la couleur des denrées contenues dans la barquette.This device is very complicated to manufacture. In the variant of FIGS. 4, 5 and 6, provision is made to further complicate it, by applying a sticker, that is to say a support provided with a layer of adhesive, such as a label, to the underside of non-return valves to prevent accidental opening by shock, deformation or others during storage. This sticker must be diluted hot and only adhere after cooling. In another variant of FIGS. 7, 8 and 9, the tray is sealed with a complex of two films laminated to each other with the exception of uncoated longitudinal strips. In the variant of FIGS. 10, 11 and 12, the upper orifice of a central tube is closed or released by a sealing film which acts like a membrane. In another variant of FIGS. 13, 14 and 15, an orifice formed on the flat edge of the tray forms the seat of a valve closed by the sealing film; no fusible substance is planned. The multiplicity of these variants, none of which has imposed itself in practice, shows that we are always looking for a safe, but simple, way to allow the air and water vapor contained in the container to s' escape during cooking, when there is overpressure, while preventing outside air from entering the tray during cooling, when the vacuum occurs inside, so that food or the like is pasteurized or sterilized during cooking in a sterile packaging, which ensures conservation of several weeks, even without freezing or other complementary means while preserving the color of the foodstuffs contained in the tray.

Pour y parvenir, le brevet français No 89 17 528 décrit une barquette pourvue d'une languette articulée sur le bord, repliée vers l'intérieur après remplissage par les aliments et avant scellement du film obturateur, ladite languette articulée comportant sur sa face horizontale un siège perforé dans lequel est déposée une goutte de résine composite devenant poreuse à une température déterminée.To achieve this, French patent No 89 17 528 describes a tray provided with a tongue hinged on the edge, folded inwards after filling with food and before sealing the sealing film, said hinged tongue having on its horizontal face a perforated seat in which a drop of composite resin is deposited which becomes porous at a determined temperature.

Cependant, ce conditionnement nécessite, outre une résine devenant poreuse, un outil de scellement complexe capable, simultanément, de souder le film obturateur tout autour de la barquette et tout autour du siège, et de perforer le film à l'endroit précis où est située la goutte de résine composite fusible grâce à une pointe prévue à cet effet. En outre, la complexité de la barquette elle-même rend la réalisation des moules délicate et onéreuse, et la languette articulée exige une manipulation supplémentaire pour sa mise en position.However, this packaging requires, in addition to a resin becoming porous, a complex sealing tool capable, simultaneously, of sealing the sealing film all around the tray and all around the seat, and of perforating the film at the precise location where it is located. the drop of fusible composite resin thanks to a point provided for this purpose. In addition, the complexity of the tray itself makes the production of molds delicate and expensive, and the hinged tongue requires additional manipulation for its positioning.

L'objet de la présente demande est une barquette permettant la suppression de ces inconvénients. En effet, elle ne nécessite pas de languette articulée et est donc plus simple et moins onéreuse. Le moule de fabrication est également moins cher à fabriquer et l'outil de scellement ne nécessite pas de pointe pour perforer le film à l'endroit de la goutte de résine fusible, le scellement ayant lieu automatiquement par les seuls effets du traitement thermique appliqué habituellement à une barquette et du refroidissement.The object of the present application is a tray allowing the elimination of these drawbacks. Indeed, it does not require an articulated tongue and is therefore simpler and less expensive. The manufacturing mold is also cheaper to manufacture and the sealing tool does not require a point to perforate the film at the location of the drop of fusible resin, the sealing taking place automatically by the sole effects of the heat treatment usually applied. to a tray and cooling.

Le récipient suivant l'invention comprend un corps à rebord operculé hermétiquement par un film et ayant un trou ménagé dans le rebord, caractérisé par une couche en une substance, ayant un point de fusion compris entre 65°C et 150°C, interposée entre le film et la partie du rebord autour du trou.The container according to the invention comprises a rim body hermetically sealed with a film and having a hole in the rim, characterized by a layer of a substance, having a melting point between 65 ° C and 150 ° C, interposed between the film and the edge part around the hole.

La couche peut être déposée sur le film ou sur le rebord. La substance est, de préférence, une colle fusible, notamment alimentaire, telle que des colles Hot-melt alimentaires de viscosité appropriée. Ce peut être notamment des hot-melt à base de résine terpénique et/ou de polymère vinylique. Un exemple de hot-melt est le suivant:

  • Huile:   ∼ 10% en poids
  • Résine terpène phénolique   ∼ 50% en poids
  • Ethyl vinyl acétate (28% d'acétate de vinyle):   ∼ 25% en poids
  • Ethyl vinyl acétate (33% d'acétate de vinyle):   ∼ 5% en poids
  • Polymère amorphe:   ∼ 10% en poids
The layer can be deposited on the film or on the edge. The substance is preferably a fusible glue, in particular a food glue, such as food hot-melt glues of appropriate viscosity. It may in particular be hot-melt based on terpene resin and / or vinyl polymer. An example of a hot melt is as follows:
  • Oil: ∼ 10% by weight
  • Phenolic terpene resin ∼ 50% by weight
  • Ethyl vinyl acetate (28% vinyl acetate): ∼ 25% by weight
  • Ethyl vinyl acetate (33% vinyl acetate): ∼ 5% by weight
  • Amorphous polymer: ∼ 10% by weight

Sur les dessins schématiques annexés, donnés à titre d'exemple non limitatif d'une des formes de réalisation de l'objet de l'invention :

  • la figure 1 représente une coupe verticale d'une barquette avec résine fusible disposée autour de l'orifice, avant cuisson de la préparation alimentaire,
  • les figures 2 et 3 montrent la même barquette, respectivement durant la cuisson du produit, avec la valve fusible ouverte, et après cuisson, la valve fusible étant refermée, et
  • les figures 4 et 5 représentent, durant les mêmes phases que les figures 2 et 3, une barquette avec résine fusible disposée sur le film assurant sa fermeture.
In the appended schematic drawings, given by way of nonlimiting example of one of the embodiments of the subject of the invention:
  • FIG. 1 represents a vertical section of a tray with fusible resin placed around the orifice, before cooking the food preparation,
  • FIGS. 2 and 3 show the same tray, respectively during the cooking of the product, with the fuse valve open, and after cooking, the fuse valve being closed, and
  • Figures 4 and 5 show, during the same phases as Figures 2 and 3, a tray with fusible resin disposed on the film ensuring its closure.

La barquette, figures 1 à 3, est constituée d'un corps 2 et d'une valve thermofusible formée d'un simple orifice 10 d'un diamètre de 0,7 à 2 mm pratiqué sur le rebord 3 du corps 2, de préférence le plus près possible de l'arête interne 11, une fine couche de résine thermofusible 12 étant déposée tout autour de l'orifice, sur ledit rebord.The tray, Figures 1 to 3, consists of a body 2 and a hot-melt valve formed by a single orifice 10 with a diameter of 0.7 to 2 mm formed on the rim 3 of the body 2, preferably as close as possible to the internal edge 11, a thin layer of hot-melt resin 12 being deposited all around the orifice, on said rim.

Après remplissage de produits alimentaires, la barquette est operculée à l'aide d'un film 7 soudé sur son pourtour. Durant la cuisson ou la stérilisation du contenu 6, le film 7 se soulève sous l'effet de la surpression qui se crée à l'intérieur, ce qui libère l'orifice 10 et permet le dégazage (flèche 13, figures 2 et 4) des produits et l'évacuation de la pression intérieure de la barquette qui s'effectuent au travers de cet orifice alors que la résine thermofusible 12 est à l'état liquide. Ainsi, durant la phase de la cuisson, l'air, la vapeur d'eau et les gaz 5 pourront s'échapper par la valve fusible, l'orifice mettant l'intérieur de la barquette 2 en communication avec l'extérieur.After filling with food products, the tray is sealed with a film 7 welded around its periphery. During the cooking or sterilization of the contents 6, the film 7 lifts under the effect of the overpressure which is created inside, which frees the orifice 10 and allows degassing (arrow 13, FIGS. 2 and 4) products and the evacuation of the internal pressure of the tray which takes place through this orifice while the hot-melt resin 12 is in the liquid state. Thus, during the cooking phase, the air, the water vapor and the gases 5 may escape through the fuse valve, the orifice bringing the inside of the tray 2 into communication with the outside.

Au terme de la cuisson ou de la stérilisation, un refroidissement rapide intervient par un moyen connu: air froid, douchage d'eau glacée ou procédé cryogénique. Cette opération a pour effet de créer, par différence de température, le vide à l'intérieur de la barquette. Le film 7 d'operculage, lors de cette importante dépression, est aspiré vers l'intérieur de la barquette et se plaque sur l'arête interne 11 de celle-ci, obturant en même temps l'orifice 10. La résine thermofusible 12 assure alors un collage étanche du film sur le rebord 3 de la barquette empêchant l'air extérieur d'y pénétrer (figures 3 et 5).At the end of cooking or sterilization, rapid cooling takes place by known means: cold air, showering with ice water or a cryogenic process. This operation has the effect of creating, by temperature difference, the vacuum inside the tray. The sealing film 7, during this significant depression, is drawn towards the inside of the tray and is pressed onto the internal edge 11 of the latter, at the same time closing the orifice 10. The hot-melt resin 12 ensures then a tight bonding of the film on the rim 3 of the tray preventing outside air from entering it (Figures 3 and 5).

La fine couche de résine thermofusible peut, dans un autre exemple d'application, être enduite sur la face interne du film 7, soit en des endroits repérés correspondant à l'emplacement du ou des orifices 10 de la barquette (figures 4 et 5), soit en une couche uniforme sur toute la surface du film.The thin layer of hot-melt resin can, in another example of application, be coated on the internal face of the film 7, either in marked locations corresponding to the location of the orifice (s) 10 of the tray (Figures 4 and 5) , or in a uniform layer over the entire surface of the film.

Le vide créé dans la barquette 2 par différence de température ajoute aux qualités de préservation des produits alimentaires, qui sont à l'abri des risques d'oxydation. C'est aussi par exemple que les couleurs des légumes verts sont parfaitement conservées.The vacuum created in tray 2 by temperature difference adds to the preservation qualities of food products, which are immune to the risk of oxidation. It is also for example that the colors of green vegetables are perfectly preserved.
