Description

DOMAINE DE L'INVENTIONFIELD OF THE INVENTION

L'invention s'inscrit dans le domaine des emballages et autres conditionnements de produits alimentaires, quelle que soit leur nature, et par exemple de plats cuisinés ou autres, type salaisons, pièces de boucherie, de poissonnerie, etc.The invention is in the field of packaging and other packaging of food products, whatever their nature, and for example cooked or other dishes, such as cured meat, butcher's pieces, fishmongers, etc.

ETAT ANTERIEUR DE LA TECHNIQUEPRIOR STATE OF THE TECHNIQUE

Depuis longtemps déjà, les produits alimentaires sont proposés aux consommateurs par exemple sous forme de plats cuisinés préparés, ou encore en détail, par exemple en tranches (charcuterie), ou en morceaux (boucherie), etc...For a long time now, food products have been offered to consumers for example in the form of prepared ready-made meals, or in detail, for example in slices (deli meats), or in pieces (butchery), etc.

Ces produits alimentaires sont conditionnés dans des barquettes ou dans des sacs, que l'ont rend étanches, s'agissant du sac en le thermoscellant au niveau de son ouverture, après éventuelle mise sous vide, et pour les barquettes, après scellement d'un film thermoscellable à la périphérie du rebord supérieur de ladite barquette.These food products are packaged in trays or in bags, which have made it waterproof, with regard to the bag by heat-sealing it at its opening, after possible evacuation, and for the trays, after sealing of a heat-sealable film at the periphery of the upper rim of said tray.

Afin de prolonger la date limite de consommation, il est connu d'introduire dans l'emballage ainsi défini, et avant thermoscellage, un gaz, notamment un gaz neutre, et par exemple un mélange d'azote et de dioxyde de carbone.In order to extend the use-by date, it is known to introduce into the packaging thus defined, and before heat-sealing, a gas, in particular a neutral gas, and for example a mixture of nitrogen and carbon dioxide.

La présence d'un tel gaz est connue pour limiter notamment la prolifération des bactéries des denrées alimentaires présentes dans l'emballage.The presence of such a gas is known to limit in particular the proliferation of bacteria of foodstuffs present in the package.

S'agissant des barquettes de l'état antérieur à la technique, afin de permettre le conditionnement des produits alimentaires sous atmosphère protectrice, on met en oeuvre des thermoscelleuses de barquettes semi-automatiques d'un coût particulièrement élevé en raison de leur technologie, et susceptibles de n'être amorties que pour de très grandes quantités de produits à conditionner.As regards trays of the prior art state, in order to allow the packaging of food products in a protective atmosphere, semi-automatic tray sealers are used which are particularly expensive because of their technology, and likely to be amortized only for very large quantities of products to be packaged.

La présente invention vise à simplifier l'opération de thermoscellage et de mise sous vide, ou sous atmosphère neutre ou protectrice, et de ne mettre en oeuvre que des thermoscelleuse d'un type beaucoup plus courant, et surtout beaucoup moins cher.The present invention aims to simplify the operation of heat sealing and evacuation, or in a neutral or protective atmosphere, and to use only heat sealer of a much more common type, and especially much cheaper.

EXPOSE DE L'INVENTIONSUMMARY OF THE INVENTION

L'invention propose donc une barquette pour produits alimentaires, définie par un fond duquel s'étendent des parois latérales aptes à définir un volume de réception dudit produit alimentaire à conditionner, le bord supérieur libre desdites parois latérales définissant à leur tour une surface de scellement d'un film thermoscellable.The invention thus proposes a tray for food products, defined by a bottom from which lateral walls extend, able to define a receiving volume of said food product to be conditioned, the free upper edge of said side walls defining in turn a sealing surface. a heat-sealable film.

Selon l'invention, l'un des bords présente une zone de thermoscellage élargie, et le même bord définit en outre un évidemment s'étendant au-delà de la zone de thermoscellage elargie, ledit évidement étant apte à permettre, après scellement du film thermoscellable sur les trois autres bords adjacents, l'introduction d'un gaz neutre ou d'un gaz de protection, par le biais de dispositifs appropriés.According to the invention, one of the edges has an enlarged heat-sealing zone, and the same edge further defines an element extending beyond the expanded heat-seal zone, said recess being able to allow, after sealing of the film heat-sealable on the other three adjacent edges, the introduction of a neutral gas or a shielding gas, by means of appropriate devices.

En d'autres termes, l'invention consiste à prévoir une barquette d'un type en soit connu, mais cependant régulièrement modifiée, de telle sorte que l'une de ses parois latérales permettent sa compatibilité avec des machines thermoscelleuse d'un type traditionnel, pour autoriser l'introduction de tels gaz neutres, alors même que la barquette en question à déjà reçue son film de thermoscellage. En bref, l'invention consiste à s'affranchir des machines de thermoscellage perfectionnées et d'un prix de revient prohibitif.In other words, the invention consists in providing a container of a type that is known, but nevertheless regularly modified, so that one of its side walls makes it compatible with heat sealing machines of a traditional type. , to allow the introduction of such neutral gases, even though the tray in question has already received its heat sealing film. In short, the invention is to overcome the improved heat sealing machines and a prohibitive cost.

Selon l'invention, l'évidemment en question est positionné de manière sous jacente par rapport au plan supérieur de la barquette, c'est-à-dire par rapport au plan dans lequel s'inscrit le film de thermoscellage.According to the invention, the obvious in question is positioned in an underlying way with respect to the upper plane of the tray, that is to say with respect to the plane in which the heat-sealing film is inscribed.

La barquette est susceptible d'être réalisée en matière plastique, notamment en polypropylène, polystyrène, en CPET (polyéthylène téréphtalate cristallin) et en APET (polyéthylène téréphtalate amorphe), et notamment être thermoformée ou injectée. Elle peut également être réalisée en carton, voire en aluminium, le bord supérieur libre des parois latérales recevant alors un film adapté, pour pouvoir permettre le thermoscellage.The tray may be made of plastic, in particular polypropylene, polystyrene, CPET (crystalline polyethylene terephthalate) and APET (polyethylene terephthalate amorphous), and in particular be thermoformed or injected. It can also be made of cardboard, or even aluminum, the free upper edge of the side walls then receiving a suitable film, to enable heat sealing.

DESCRIPTION DETAILLEE DE L'INVENTIONDETAILED DESCRIPTION OF THE INVENTION

On a donc représenté au sein de la figure 1, une barquette 1 de conditionnement, de stockage et de conservation de produits alimentaires, conforme à l'invention.So we represented in the figure 1 , a tray 1 for packaging, storage and preservation of food products, according to the invention.

Celle-ci est de forme générale parallélépipédique. Elle comporte un fond 2, duquel s'étendent en direction du haut quatre parois latérales 3, 4, 5 et 6. This one is of parallelepipedic general shape. It comprises a bottom 2, from which extend in the direction of the top four side walls 3, 4, 5 and 6.

L'ensemble constitué par le fond 2 et les parois latérales 3 - 6 définit ainsi un volume apte à recevoir tous types de produits alimentaires, et notamment de la viande rouge, du poisson frais, de la saucisserie, des produits traiteurs, voir des plats cuisinés, etc...The assembly constituted by the bottom 2 and the side walls 3 - 6 thus defines a volume suitable for receiving all types of food products, and in particular red meat, fresh fish, sausage, catering products, see dishes cooked, etc ...

Cette barquette est typiquement réalisée en matière plastique thermoformée ou injectée. Cependant, il peut être envisagé de la réaliser en carton, ou en aluminium.This tray is typically made of thermoformed plastic material or injected. However, it can be envisaged to make it in cardboard, or aluminum.

Le bord supérieur libre 7, 8, 9 et 10 des parois latérales 3 - 6 définit une zone sensiblement plane, et sensiblement parallèle au fond 2. Bien évidemment, ce bord supérieur est continu sur toute la périphérie de la barquette.The upper free edge 7, 8, 9 and 10 of the side walls 3 - 6 defines a substantially flat area, and substantially parallel to the bottom 2. Obviously, this upper edge is continuous over the entire periphery of the tray.

Cette zone plane est destinée à constituer une zone de thermoscellage d'un film 11 en matière plastique thermoscellable compatible avec les matériaux utilisés pour la fabrication des barquettes.This flat area is intended to constitute a heat-sealing zone of a heat-sealable plastic film 11 compatible with the materials used for the manufacture of the trays.

Ce qui caractérise l'invention par rapport aux barquettes de l'état antérieur de la technique, c'est tout d'abord l'un des bords supérieurs libres, et en l'espèce le bord 10. Celui-ci présente une zone élargie, et notamment une plage de soudure élargie 12. What characterizes the invention compared to trays of the prior art is first of all one of the free upper edges, and in this case the edge 10. This has an enlarged area , and in particular an enlarged weld seam 12.

En outre, et selon une autre caractéristique de l'invention, ledit bord supérieur 10 comporte un évidement 13, avantageusement issu de moulage (ou de thermoformage). Cet évidement 13 s'étend en dessous du plan défini par le bord supérieur libre desdites parois latérales, c'est-à-dire en dessous du plan de thermoscellage défini lui-même par le film 11, ainsi qu'on peut bien l'observer notamment sur la figure 3.In addition, and according to another characteristic of the invention, said upper edge 10 has a recess 13, advantageously derived from molding (or thermoforming). This recess 13 extends below the plane defined by the free upper edge of said side walls, that is to say below the heat sealing plane itself defined by the film 11, as well as the observe especially on the figure 3 .

Cette zone particulière est destinée à permettre l'insertion à ce niveau d'une ou de plusieurs buses d'introduction d'un gaz alimentaire au sein du volume défini par ladite barquette, après thermoscellage du film 11 sur trois bords consécutifs 7, 8 et 9 autres que le bord 10 pourvu de cet évidement 13. This particular zone is intended to allow insertion at this level of one or more feed gas introduction nozzles within the volume defined by said tray, after heat sealing of the film 11 on three consecutive edges 7, 8 and 9 other than the edge 10 provided with this recess 13.

On peut bien visualiser le principe ainsi décrit au sein de la figure 3, dans laquelle une flèche matérialise l'une desdites buses.We can clearly visualize the principle thus described within the figure 3 , in which an arrow materializes one of said nozzles.

On comprendra mieux l'invention à l'observation des figures 4a à 4c, propres à matérialiser le mode de fonctionnement de la barquette conforme à l'invention.The invention will be better understood in the observation of Figures 4a to 4c , suitable for materializing the mode of operation of the tray according to the invention.

Ainsi donc en figure 4a, on a représenté la barquette vue de dessus, déjà revêtue du film de thermoscellage soudé sur trois bords adjacents. Bien évidemment, cela suppose que le produit alimentaire à conditionner est déjà présent au sein de la barquette.So so in figure 4a the tray seen from above, already coated with the heat sealing film welded to three adjacent edges, is shown. Of course, this assumes that the food product to be packaged is already present in the tray.

La zone de soudure en question est matérialisée en hachures.The weld zone in question is materialized in hatching.

Au sein de la figure 4b, on a matérialisé par une flèche l'introduction du gaz neutre au sein de la barquette, introduction rendue possible par l'évidement 13 caractéristique de l'invention.Within the figure 4b the introduction of the neutral gas into the tray has been marked by an arrow, an introduction made possible by the recess 13 characteristic of the invention.

Enfin lors de l'étape 4c, on soude le quatrième bord au niveau de la plage de soudure spécifique 12 du bord 10 de ladite barquette, au moyen d'outils appropriés 14 illustrés sur la figure 3.Finally, during step 4c, the fourth edge is welded at the specific welding area 12 of the edge 10 of said tray, by means of appropriate tools 14 illustrated in FIG. figure 3 .

Cette opération est réalisée au sein d'une machine à cloche, d'un type en soi connu, telle que par exemple commercialisée sous les références suivantes :

  • le modèle C200G de la société MULTIVAC ;
  • le modèle PLUS VAC 21 de la société KOMET ;
  • le modèle BOXER 42 de la société HENKELMAN.
This operation is carried out within a bell machine, of a type known per se, such as for example marketed under the following references:
  • the C200G model from MULTIVAC;
  • the PLUS VAC 21 model from KOMET;
  • the BOXER 42 model from the company HENKELMAN.

On conçoit de fait tout l'intérêt de la présente invention qui permet de manière simple de pouvoir introduire un gaz neutre ou une atmosphère protectrice au sein d'un emballage de conditionnement de produits alimentaires, sans passer par des machines de thermoscellage onéreuses.It is conceivable in fact all the advantages of the present invention that allows a simple way to introduce a neutral gas or a protective atmosphere in a packaging of food products, without going through expensive heat sealing machines.

On a représenté l'évidement au niveau de l'un des bords de la barquette. Il est bien entendu que cet évidement pourrait se situer sur n'importe lequel des côtés de ladite barquettte.The recess is shown at one of the edges of the tray. It is understood that this recess could be on any of the sides of said barquettte.

En outre, l'invention est susceptible d'être mise en oeuvre quelle que soit la taille des barquettes.In addition, the invention is capable of being implemented irrespective of the size of the trays.
