Description

Procédé d'élaboration de structures composites étanches pouvant être comestibles pour présenter, contenir ou emballer des produits agro-alimentaires.Process for developing waterproof composite structures which can be edible for presenting, containing or packaging agrifood products.

L'invention concerne un procédé d'élaboration de structures composites étanches pouvant être comestibles pour présenter, contenir ou emballer des produits agro-alimentaires destinés à la consommation humaine ou animale.The invention relates to a process for developing watertight composite structures which can be edible for presenting, containing or packaging agri-food products intended for human or animal consumption.

Des contenants comestibles connus, sont réalisés en pain azyme et sont généralement destinés à la présentation de sucreries en poudre, d'autres, en forme de cornet, sont confectionnés en patisserie légère du genre gaufrette, sont destinés à la dégustation des glaces. On connait également toutes les pâtes cuites en forme, destinées à recevoir des plats cuisinés tels que les bouchées à la reine, tartes, pizza,etc.., ces contenants comestibles ramollissent et se délitent sous l'action de l'humidité et doivent donc être sur-conditionnés dans des emballages en aluminium, carton sulfurisé ou en matière plastique.Known edible containers are made of unleavened bread and are generally intended for the presentation of powdered sweets, others, in the shape of a cone, are made in light pastry of the wafer type, are intended for tasting ice creams. We also know all pasta cooked in shape, intended to receive cooked dishes such as Queen's bites, pies, pizza, etc., these edible containers soften and disintegrate under the action of humidity and must therefore be over-conditioned in aluminum, parchment or plastic packaging.

Les contenants ou emballages couramment utilisés pour la présentation de produits agro-alimentaires frais ou surgelés, sont réalisés en carton, en aluminium ou en plastique rigide, obtenus par injection ou par thermoformage - le polystyrène, le polyèthylène, le polypropylène, le PVC, les matière plastiques alvéolées du type polystyrène expansé sont transformées.The containers or packaging commonly used for the presentation of fresh or frozen food products, are made of cardboard, aluminum or rigid plastic, obtained by injection or thermoforming - polystyrene, polyethylene, polypropylene, PVC, foam plastics of the expanded polystyrene type are transformed.

Ces emballages ont l'inconvénient de n'être pas réutilisables, ils sont jetés et polluent l'environnement. Elaborés à partir de produits pétroliers, les emballages en matière plastique, et plus particulièrement ceux réalisés en polystyrène expansé présentent l'inconvénient d'isoler du froid les produits frais, mais surtout leur stabilité de polymèrisation n'est atteinte que plusieurs dizaines de jours après leur fabrication, il en résulte une atteinte chimique sur les produits qu'ils contiennent limitant leur conservation.These packaging have the disadvantage of not being reusable, they are thrown away and pollute the environment. Developed from petroleum products, plastic packaging, and more particularly that made of expanded polystyrene, has the drawback of isolating fresh products from the cold, but above all their polymerization stability is only reached several tens of days after. their manufacture, it results in a chemical attack on the products they contain limiting their conservation.

L'invention à pour but d'éliminer ces inconvénients en fournissant notamment, des emballages ou des contenants qui peuvent être comestibles, réalisés à partie de produits de qualité alimentaire, résistant à la chaleur ambiante et au froid et susceptibles d'être cuits , ceux-ci pourront être destinés à la présentation et à la contenance d'un plat et dégustés avec celui-ci, par exemple, un fond de tarte, la pâte d'une pizza, soit, s'ils ont présenté et conditionné de la viande,du poisson ou autre produit frais exposé dans une gondole réfrigérée, donnés comme nourriture aux animaux.The invention aims to eliminate these drawbacks by providing, in particular, packaging or containers which may be edible, made from food-grade products, resistant to ambient heat and cold and capable of being cooked, those -these could be intended for the presentation and the capacity of a dish and tasted with this one, for example, a bottom of pie, the dough of a pizza, that is, if they presented and conditioned meat , fish or other fresh produce displayed in a refrigerated gondola, fed to animals.

On comprendra l'intérêt de la présente invention en offrant un produit nourrissant, non polluant et confectionnable avec des matières premières naturelles.It will be understood the advantage of the present invention by providing a nourishing, non-polluting product that can be made with natural raw materials.

L'invention telle qu'elle est caractèrisée dans les revendications concerne à cet effet un procédé d'élaboration de struc turescomposites étanches pouvant être comestibles pour présenter contenir ou emballer des produits agro-alimentaires caractèrisé en ce qu'il consiste à isoler sous vide d'air par la mise en oeuvre d'une enveloppe étanche à partir d'au moins un film en matière thermoplastique de qualité alimentaire déchirable et dissociable d'une structure confectionnée à partir d'au moins une matière de préférence comestible destinée à présenter, contenir et emballer un produit agro-alimentaire pour la consommation humaine ou animale.The invention as characterized in the claims relates for this purpose to a process for the production of waterproof composite structures which may be edible in order to present contain or pack agri-food products, characterized in that it consists in insulating under vacuum. air by the implementation of a sealed envelope from at least one film of thermoplastic material of tearable food quality and separable from a structure made from at least one preferably edible material intended to present, contain and pack an agrifood product for human or animal consumption.

Selon la présente invention, la structure est réalisée à base d'au moins une matière comestible d'origine végétale et/ou animale, crue ou cuite, dans laquelle on aura pu introduire un produit texturant de préférence d'origine naturelle, permettant à la structure d'être plus solide et d'avoir une meilleure tenue.According to the present invention, the structure is made from at least one edible material of plant and / or animal origin, raw or cooked, into which a texturing product, preferably of natural origin, may have been introduced, allowing the structure to be more solid and to hold better.

Selon l'invention, la matière comestible pourra être neutre, assaisonnée, sucrée, salée, aromatisée ou élaboré à partir d'éléments naturels ou fabriqués comprenant : les produits traditionnels, les produits de remplacement ou les produits reconstitués.According to the invention, the edible material may be neutral, seasoned, sweet, salty, flavored or made from natural or manufactured elements comprising: traditional products, replacement products or reconstituted products.

La structure pourra être confectionnée avec des matières non alimentaires comme la pâte à papier, le carton imprimé prédécoupé, en bois tréssé ou en bois déroulé etc..The structure can be made with non-food materials such as paper pulp, pre-cut printed cardboard, braided wood or peeled wood, etc.

D'autres caractéristiques et avantages de la présente invenvent ion apparaîtront au cours de la description qui va suivre d'un mode particulier de réalisation, donné à titre d'exemple non limitatif, en regard des dessins qui représentent - la Figure 1, la coupe d'une portion de structure composite selon l'invention, - la Figure 2, un schéma montrant la disposition d'aménagements pour dissocier l'enveloppe de la structure selon l'invention.Other characteristics and advantages of the present invention will appear during the following description of a particular embodiment, given by way of nonlimiting example, with reference to the drawings which represent - Figure 1, the section of a portion of composite structure according to the invention, - Figure 2, a diagram showing the arrangement of arrangements for dissociating the envelope of the structure according to the invention.

Sur la figure 1 on a représenté une coupe partielle d'une structure composite (1) de forme appropriée à l'usage dont elle est destinée : emballage, présentation de viande, charcu- terie, poisson, légumes, fromages, fond de gâteau, tarte, bouchée à la reine, boîte à oeufs, à gâteaux ou tout autre produit agro-alimentaire. La matière (2) peut, selon l'usage prévu, être à base d'au moins un produit comestible cru ou cuit ou-à base de produit non comestible ; bien entendu on pourra combiner suivant le cas les deux possibilités.FIG. 1 shows a partial section of a composite structure (1) of a shape suitable for the use for which it is intended: packaging, presentation of meat, cured meats, fish, vegetables, cheeses, cake bottom, pie, queen bite, egg, cake box or any other food product. The material (2) may, according to the intended use, be based on at least one edible raw or cooked product or-based on inedible product; of course we can combine the two possibilities depending on the case.

La matière (2) comestible sera de préférence d'origine végétale pouvant être mélangé avec des produits d'origine animale, des pâtes confectionnées avec des farines de céréales, telles que blé, seigle, mals, riz, orge ou autres farines comme le soja, les haricots, fêves, etc-...Ces pâtes selon la nature de la farine choisie pourra contenir des ingrèdients : sel, sucre, aromates, levures, assaisonnements divers, etc.. ou des produits appètents pour les chats, les chiens et autres animaux.The edible material (2) will preferably be of vegetable origin which can be mixed with products of animal origin, pasta made with cereal flours, such as wheat, rye, mal, rice, barley or other flours such as soybeans , beans, beans, etc. -... These pasta depending on the type of flour chosen may contain ingredients: salt, sugar, flavorings, yeasts, various seasonings, etc. or palatable products for cats, dogs and other animals.

La matière (2) comestible confectionnant la structure (3) pourra être élaborée à partir d'aliments naturels ou fabriqués comprenant : les produits traditionnels, les produits de remplacement ou mes produits reconstitués.The edible material (2) making up the structure (3) can be made from natural or manufactured foods including: traditional products, replacement products or my reconstituted products.

Avantageusement, on pourra incorporer dans les matières (2) à base de produits comestibles, un corps texturant de qualité alimentaire thermo-irréversible comme les alginates, pectines ou thermo-réversable comme les gommes agar, carraghénanes, caroube, guar, xanthane, les sucroglycèrides, amidons, maltodextrines, polysaccharides, carboxyméthylcelluloses ou tout autre produit gèlifiant susceptible d'améliorer la résistance de la structure (3) formant le contenant.Advantageously, it is possible to incorporate into the materials (2) based on edible products, a texturing body of thermo-irreversible food quality such as alginates, pectins or thermo-reversible such as agar gums, carrageenans, locust bean, guar, xanthan, sucroglycerides , starches, maltodextrins, polysaccharides, carboxymethylcelluloses or any other gelling product capable of improving the resistance of the structure (3) forming the container.

La matière (2) constitutive de la structure (3) extrudée, moulée dans la forme du contenant choisi, sera de préférence suffisamment chaude par exemple après la cuisson, pour qu'une fois intercalé entre les films (4) (5) en matière thermoplastique de qualité alimentaire, elle les chauffe de façon à ce qu'ils se ramollissent afin qu'ils l'épousent sans contrainte sur tous les subjectiles (6)(7) de la structure (3) par effet de thermoformage.The material (2) constituting the extruded structure (3), molded in the shape of the chosen container, will preferably be hot enough for example after cooking, so that once inserted between the films (4) (5) thermoplastic of food quality, it heats them so that they soften so that they marry without constraint on all the substrates (6) (7) of the structure (3) by thermoforming effect.

Selon l'invention on procède au vide d'airkntre les films (4) (5), disposés en regard de chacun des subjectiles (6)(7) de la structure (3) chaude, l'action du vide fait se plaquer les films thermoplastiques (4)(5) sur la structure (3), selon le type de matèriau mis en oeuvre comme certaines qualités de polyoléfines électrostatiques -polypropylène,polyèthylèneon pourra obtenir une union par osmose au niveau du flanc (8) périphérique de la -structure (3) assurant l'herméticité de la structure composite (1), le phénomène d'aspiration des films (4)(5) dû au vide -relatif- sera accentué par le refroidissement de l'air contenu dans la matière (2) conférant d'excellentes qualités de tenue et de rigidité à la structure composite (1).According to the invention, there is an air vacuum between the films (4) (5), placed opposite each of the substrates (6) (7) of the hot structure (3), the action of the vacuum causes the thermoplastic films (4) (5) on the structure (3), depending on the type of material used as certain qualities of electrostatic polyolefins -polypropylene, polyethylene may be able to obtain a union by osmosis at the peripheral flank (8) of the - structure (3) ensuring the hermeticity of the composite structure (1), the phenomenon of suction of the films (4) (5) due to the relative vacuum will be accentuated by the cooling of the air contained in the material (2 ) giving excellent qualities of strength and rigidity to the composite structure (1).

La matière (2) de la structure (3) constituée de certaines pâtes peu résistantes, sablées, feuilletées ou trop fines on aura alors recours soit à un renfort soit à un film thermoplastique de qualité alimentaire plus épais pour assurer la résistance nécessaire.The material (2) of the structure (3) made up of certain doughs that are not very resistant, sanded, flaky or too fine, then a reinforcement or a thicker food-grade thermoplastic film will be used to provide the necessary resistance.

Le flanc (8) périphérique de la structure composite (1) est découpé, après l'opération du vide dTair, à l'aide d'un outil(9) pouvant être du type coupant-soudant, c'est à dire qui provoque, tout en découpant la pièce, une impulsion thermique faisant fondre les lèvres (10) du flanc (8) qui se soudent assurant une étanchéité absolue de la structure composite (1).The peripheral flank (8) of the composite structure (1) is cut, after the air vacuum operation, using a tool (9) which may be of the cutting-welding type, that is to say which causes , while cutting the part, a thermal pulse melting the lips (10) of the sidewall (8) which are welded ensuring an absolute seal of the composite structure (1).

Afin de pouvoir enlever- les films (4)(5) pour rendre utilisable la structure (3) à'des fins culinaires comme accessoire ou comme apport alimentaire, on a prévu Figure 2, au moins un des aménagements (11) ou (12) pratiqués par l'outil cou pant-soud & t (9), ces aménagements permettant de déchirer les films (4) (5) de la structure composite (1).In order to be able to remove the films (4) (5) to make the structure (3) usable for culinary purposes as an accessory or as food intake, provision has been made in Figure 2, at least one of the arrangements (11) or (12 ) made by the pant-welded neck tool & t (9), these arrangements making it possible to tear the films (4) (5) of the composite structure (1).

Le procédé selon l'invention rend étanche et hydrophobe des produits qui ne peuvent pas, de par leur nature même, avoir ces qualités, ainsi, sans dénaturer ni le contenu ni le contenant, pourra-t-on réaliser des emballages de toute sorte qui deviendront des supports culinaires, ou simplement émiéttés et donnés aux oiseaux.The method according to the invention renders products which, by their very nature, cannot have these qualities waterproof and hydrophobic, so, without denaturing either the content or the container, will it be possible to produce packaging of any kind which will become culinary supports, or simply crumbled and given to birds.

Dans la matière (2) constitutive de la structure (3) on pourra incorporer selon le cas, des produits pour faire gonfler la pâte afin de rendre la structure composite (1) isolante pour conditionner les produits surgelés ou transporter les glaces.In the material (2) constituting the structure (3) may be incorporated as appropriate, products to swell the dough to make the composite structure (1) insulating to package frozen products or transport ice cream.

Il va de soi que de nombreuses variantes peuvent être introduites sanspour autant sortir du cadre de l'invention, comme par exemple , si la matière de la structure le permet, procéder à son trempage ou enduisage à chaud, avec un mélange de
paraffine et de sucroglycèrides. It goes without saying that many variants can be introduced without departing from the scope of the invention, such as for example, if the material of the structure allows, proceed to its quenching or hot coating, with a mixture of
paraffin and sucroglycerides.
