Description

La présente invention concerne un dispositif à usage unique de présentation et de cuisson notamment de grains de maïs pour la fabrication de pop corn.The present invention relates to a single-use device for presentation and cooking including corn kernels for making popcorn.

La présente invention est décrite en regard d'un produit bien connu le pop-corn mais on peut envisager d'autres applications notamment des denrées apéritifs tels que des amuse-gueules de toute forme, boule, frites, réalisés à partir de semoule de maïs transformée en semoule et comprimée et préparée de façon adaptée.The present invention is described with reference to a well-known product popcorn but other applications can be envisaged including aperitifs such as appetizers of any shape, ball, fries, made from cornmeal processed into semolina and compressed and prepared in a suitable way.

Pour des raisons de simplification d'explication et compte tenu du fait que le dispositif est mis en oeuvre dans tous les cas de façon totalement identique, la description est faite pour le grain de maïs naturel et l'obtention de pop-corn.For reasons of simplification of explanation and taking into account the fact that the device is implemented in all cases completely identical, the description is made for natural corn grain and obtaining popcorn.

On sait depuis longtemps que de grains de maïs lorsqu'ils sont chauffés, éclatent en formant une corolle blanche, le produit étant dénommé pop corn.It has long been known that corn kernels when heated, burst into a white corolla, the product being called popcorn.

Ces grains de maïs doivent être placés dans un récipient en présence d'un corps gras.These corn kernels must be placed in a container in the presence of a fatty substance.

Mais, avec l'avènement du four à micro-ondes, les producteurs ont proposé des grains de maïs emballés dans des poches avec de la matière grasse immobilisant les grains de maïs à froid car la matière grasse se fige.But, with the advent of the microwave oven, producers have proposed corn kernels packaged in pockets with fat immobilizing the corn kernels cold as the fat freezes.

En effet, pour assurer un éclatement efficace et le plus complet possible, il était préférable que les grains de maïs restent pressés les uns contre les autres. Les rayonnements étaient alors concentrés et on augmentait l'efficacité.Indeed, to ensure an effective burst and as complete as possible, it was preferable that the corn kernels remain pressed against each other. The radiation was then concentrated and the efficiency was increased.

Les grains de maïs eux-mêmes ne sont pas différents qu'ils soient utilisés avec un chauffage thermique ou avec un chauffage par micro-ondes. Il n'y a pas besoin d'un traitement préalable particulier. C'est l'eau contenue dans les grains qui en se transformant en vapeur provoque l'explosion de l'enveloppe du grain et la formation du pop-corn.The corn kernels themselves are no different whether they are used with thermal heating or with microwave heating. There is no need for special pre-treatment. It is the water contained in the grains that turns into steam causes the explosion of the grain envelope and the formation of popcorn.

Dans le cas de ces emballages souples, la poche est en matériau adapté pour laisser passer les micro-ondes et sans se dégrader sous leurs effets et cette poche sert également de contenant. Plus exactement, le complexe comprend au moins une couche réactive aux micro-ondes qui transmet une partie des micro-ondes, en absorbe une autre partie pour la transformer en rayonnement infrarouge et par contre réfléchit les infrarouges ainsi produit pour reconstituer les conditions de chauffage suffisantes pour provoquer l'éclatement des grains.In the case of these flexible packaging, the bag is made of material adapted to let the microwave and without degrading under their effects and this pocket also serves as a container. More exactly, the complex comprises at least one microwave reactive layer that transmits a portion of the microwaves, absorbs another portion to transform it into infrared radiation and on the other hand reflects the infrared thus produced to restore sufficient heating conditions to cause the bursting of the grains.

Par contre, la poche après cuisson reste très chaude du fait de la très faible épaisseur de l'emballage et la chaleur générée.On the other hand, the bag after cooking remains very hot because of the very small thickness of the packaging and the heat generated.

Une fois les grains éclatés, dans le cas des pop-corn sucrés si l'on veut transformer les sucres et obtenir les qualités organoleptiques engendrées par les réactions de Maillard qui donnent le goût de caramel à partir du sucre, il faut atteindre une température suffisante, ce qui rend un tel emballage complexe à réaliser.Once the grains burst, in the case of sweet popcorn if you want to transform the sugars and get the organoleptic qualities generated by Maillard reactions that give the taste of caramel from sugar, it is necessary to reach a sufficient temperature , which makes such a complex package to achieve.

Plus particulièrement, on connaît sous la dénomination Crousti Pack, un produit de ce type.More particularly, a product of this type is known under the name Crousti Pack.

Pour le consommateur, il suffit de placer l'emballage dans le four à micro-ondes, de mettre en marche ce dernier pendant la durée préconisée et de récupérer le contenant avec ses pop-corn prêts à être dégustés.For the consumer, simply place the packaging in the microwave oven, turn on the microwave for the recommended time and retrieve the container with its popcorn ready to be tasted.

C'est le gonflement des pop-corn et la génération de vapeur d'eau avec la dilatation de l'air contenu qui assurent le gonflement et le déploiement de la poche contenant initialement les grains de maïs.It is the swelling of the popcorn and the generation of water vapor with the dilation of the contained air which ensure the swelling and the deployment of the pocket initially containing the corn kernels.

Depuis, on sait que les fours à micro-ondes se sont perfectionnés et que le rayonnement est homogène et qu'il n'y a plus la nécessité de plaquer les grains les uns contre les autres.Since then, we know that microwave ovens have improved and that the radiation is homogeneous and that there is no longer the need to press the grains against each other.

Il subsiste par contre un problème qui concerne la présentation car une fois déployée la poche réalisée en complexe de films en matière plastique et/ ou papier, celle-ci n'a aucune tenue et elle ne peut pas servir de contenant de présentation. Ainsi qu'indiqué ci-avant, la poche reste extrêmement chaude après obtention des pop-corn.There is however a problem that concerns the presentation because once deployed the pocket made of complex plastic film and / or paper, it has no holding and it can not be used as a presentation container. As indicated above, the bag remains extremely hot after obtaining the popcorn.

Par contre, on comprend aussi que l'emballage initial doit nécessairement être replié pour réduire son volume. Les grains pourraient bouger dans un contenant beaucoup trop grand avant cuisson, ce qui n'est pas souhaitable et de plus, il n'est pas possible de transporter des emballages à 9/10ème vides. Il faut qu'ils soient repliés.On the other hand, it is also understood that the initial packaging must necessarily be folded to reduce its volume. The grains may move in a container too large before cooking, which is undesirable and moreover, it is not possible to transport packages to 9/10 th empty. They must be folded.

Une boîte pliable pour la cuisson du pop-corn est décrite dans le document US-5.468.939 . Cette boîte parallélépipédique comprend des parois latérales avec des rabats à montage automatique. En position à plat, les faces arrière et de dessus sont plaquées contre les faces de dessous et avant. Pour former la boîte, il suffit de pousser les bords opposés l'un vers l'autre. Les grains de maïs sont conditionnés dans une poche qui peut être introduite dans la boîte.A foldable box for cooking popcorn is described in the document US 5468939 . This parallelepipedic box includes sidewalls with self-mounting flaps. In the flat position, the back and top faces are pressed against the front and bottom faces. To form the box, simply push the opposite edges towards each other. The corn kernels are packaged in a pouch that can be introduced into the box.

Cette solution ne donne pas satisfaction car la poche n'est pas immobilisée dans la boîte pliée et empêche un pliage complet de la boîte.This solution is unsatisfactory because the pocket is not immobilized in the folded box and prevents a complete folding of the box.

Aussi, la présente invention propose un nouveau dispositif qui permet de disposer et de conserver des grains de maïs, de réaliser l'éclatement de ces grains dans un four à micro-ondes et de présenter les pop-corn obtenus.Also, the present invention provides a novel device that allows to dispose and preserve maize grains, to achieve the bursting of these grains in a microwave oven and to present the popcorn obtained.

A cet effet, la présente invention a pour objet un dispositif de présentation et de cuisson de grains de maïs pour la fabrication de pop corn selon la revendication 1.To this end, the subject of the present invention is a device for presenting and cooking corn kernels for producing popcorn according to claim 1.

Cette base est destinée à recevoir les grains de maïs bruts. Le volume de grains détermine la quantité de pop-corn qui sera obtenue. Néanmoins, on comprend qu'il faut une épaisseur réduite car le pouvoir de pénétration des micro-ondes dans les aliments reste faible, de l'ordre de 2 cm. Il faut donc limiter à cette faible hauteur la base pour obtenir l'efficacité la plus grande.This base is intended to receive the raw corn kernels. The volume of grains determines the amount of popcorn that will be obtained. Nevertheless, it is understood that a reduced thickness is necessary because the penetration power of microwaves in food remains low, of the order of 2 cm. It is thus necessary to limit to this low height the base to obtain the greatest effectiveness.

Pour augmenter le volume, il convient de jouer sur les autres dimensions.To increase the volume, it is advisable to play on the other dimensions.

La zone de compensation est pliée sur la figure 1A, avec néanmoins une amorce de dépliage en sorte de pouvoir distinguer les différentes parties. Dans la réalité des faits, la hauteur de l'ensemble apparaît comme étant sensiblement celle de la hauteur de la base.The compensation area is folded on the Figure 1A , with nevertheless a beginning of unfolding so as to be able to distinguish the different parts. In the reality of the facts, the height of the set appears to be substantially that of the height of the base.

Cette zone de compensation comprend des pliages 22 et 24, respectivement ménagés sur les faces en vis-à-vis dites faces 26 escamotables et faces 28 raidisseuses.This compensation zone comprises folds 22 and 24 respectively formed on the facing faces said retractable faces 26 and 28 stiffening faces.

Les faces 26 escamotables comportent chacune un pli 30, obtenu par rainage de la matière cartonnée, ce pli étant sensiblement au milieu de chacune des faces et parallèle à la base.The retractable faces 26 each comprise a fold 30, obtained by creasing the cardboard material, this fold being substantially in the middle of each of the faces and parallel to the base.

Les faces 28 raidisseuses comportent chacune plusieurs plis, un premier pli 32 dans la continuité des plis 30, disposés dans le plan médian. Par contre, chaque pli 32 est obtenu aussi par rainage mais comporte en partie centrale une découpe 34 permettant de constituer un fenêtre en losange, à ouverture variable durant les manoeuvres de déploiement, comme cela sera indiqué ultérieurement. La découpe 34 est linéaire et comprend éventuellement des compléments pour faciliter cette ouverture. Avantageusement, la découpe 34 peut comprendre à chaque extrémité, une découpe 35 s'étendant de manière sensiblement perpendiculaire à la découpe 34, de part et d'autre de ladite découpe 34 afin d'empêcher le déchirement de la boîte dans le prolongement de la découpe 34.The stiffening faces 28 each comprise several folds, a first fold 32 in the continuity of the folds 30, arranged in the median plane. By cons, each fold 32 is also obtained by creasing but has in the central portion a cutout 34 for constituting a diamond-shaped window, variable opening during the deployment maneuvers, as will be indicated later. The cutout 34 is linear and optionally includes complements to facilitate this opening. Advantageously, the cutout 34 may comprise at each end, a cutout 35 extending substantially perpendicularly to the cutout 34, on either side of said cutout 34 to prevent tearing of the box in the extension of the cut. cutting 34.

En outre, il est prévu des plis 36 diagonaux, également obtenus par rainage.In addition, there are provided diagonal folds 36, also obtained by creasing.

On obtient ainsi un soufflet avec des parois rigides, pliables.This gives a bellows with rigid walls, foldable.

Les moyens 18 de déploiement comprennent deux languettes 38, une par face 26 escamotable. Comme montré sur la figure 2, chaque languette est avantageusement en forme de Té. Une fente 40, est ménagée dans chaque pli 30, d'une longueur permettant le passage de la branche 42 longitudinale du Té et interdisant le passage de la branche 44 transversale. Dans ce mode de réalisation présenté, le montage est simple et purement mécanique.The deployment means 18 comprise two tongues 38, one per retractable face 26. As shown on the figure 2 each tongue is advantageously T-shaped. A slot 40 is formed in each fold 30, of a length allowing the passage of the longitudinal leg 42 of the tee and prohibiting the passage of the transverse branch 44. In this embodiment shown, the assembly is simple and purely mechanical.

La branche transversale est éventuellement collée directement sur cette face 26 escamotable mais à l'extérieur.The transverse branch is optionally glued directly on this retractable face 26 but outside.

Les moyens 20 d'ouverture/fermeture de ce contenant comprennent deux volets 46, 48 rabattables et munis chacun d'une oreille 50, 52. Chaque oreille est apte à venir immobiliser le volet opposé pour assurer un verrouillage des volets en position de fermeture du contenant.The means 20 for opening / closing this container comprise two flaps 46, 48 foldable and each provided with an ear 50, 52. Each ear is able to come to immobilize the opposite flap to ensure a locking of the flaps in the closed position. container.

Le fond du contenant est réalisé de façon connu en boîtage par quatre volets 54-60 à superposition alternée.The bottom of the container is made in known manner in a box with four shutters 54-60 alternately superimposed.

Pour avoir la certitude que les grains de maïs sont bien maintenus sans risque de passer à travers ces volets à superposition alternée, il est prévu un bac 62, représenté sur la figure 2.To be certain that the corn kernels are well maintained without risk of passing through these alternately superimposed shutters, there is provided a tray 62, shown on the figure 2 .

Ce bac est aussi réalisé en matériau absorbant l'énergie transportée par les micro-ondes et susceptible de générer des rayonnements infrarouges aptes à déclencher les réactions de Maillard lorsqu'il s'agit de grains avec sucres. Dans le cas de grains de maïs salés ou beurrés, il ne se produit aucune transformation mais l'absorption d'énergie améliore l'éclatement.This tray is also made of energy absorbing material carried by microwaves and capable of generating infrared radiation capable of triggering Maillard reactions when it comes to grains with sugars. In the case of salted or buttered corn kernels, no transformation takes place but the energy absorption improves the burst.

Pour la conservation des grains de maïs avec le degré hygrométrique nécessaire à son éclatement, de l'ordre de 14% généralement, il est nécessaire de placer le dispositif sous un film complexe adapté. Ce complexe de protection est ouvert au moment de l'utilisation comme pour tout autre produit alimentaire de ce type.For the conservation of maize grains with the moisture content necessary for its bursting, of the order of 14% generally, it is necessary to place the device under a suitable complex film. This protective complex is open at the time of use as for any other food product of this type.

La mise en oeuvre de ce dispositif de présentation et de cuisson des grains de maïs pour en faire des pop-corn est maintenant indiquée.The implementation of this device for presenting and cooking corn kernels to make popcorn is now indicated.

Le consommateur retire de son emballage le dispositif qui est sous forme pliée avec les grains de maïs immobilisés dans la base, dans le bac 62, s'il y en a un. La base permet le stockage des grains et de les immobiliser dans un espace restreint. La présence de la base permet également d'obtenir un pliage complet de la zone 16 de compensation contrairement aux dispositifs de l'art antérieur.The consumer withdraws from its packaging the device which is in folded form with corn kernels immobilized in the base, in the tray 62, if there is one. The base allows storage of grains and immobilize them in a small space. The presence of the base also makes it possible to obtain a complete folding of the compensation zone 16 in contrast to the devices of the prior art.

Le consommateur tire sur les deux languettes 38, en sorte d'écarter les deux faces 26 escamotables, au droit de chaque pli 30, ce qui a pour effet de déployer ces deux faces, d'écarter la base 14 des moyens 20 de fermeture et déployer simultanément les faces 28 raidisseuses. La fenêtre 34 se referme pour ne devenir qu'une fente et ces faces raidisseuses deviennent sensiblement planes. La découpe 34 formant fenêtre favorise le déploiement de la zone 16 de compensation et réduit la détérioration des arêtes reliant les faces 26 et 28. Cette découpe 34 est même nécessaire lorsque les faces 26 et 28 sont en forme de trapèze pour obtenir une boîte de forme pyramidale tronquée inversée.The consumer pulls on the two tabs 38, so as to separate the two retractable faces 26, at the right of each fold 30, which has the effect of deploying these two faces, to separate the base 14 of the closing means 20 and simultaneously deploy the stiffening faces 28. The window 34 closes to become a slot and these stiffening faces become substantially planar. The cutout 34 forming a window promotes the deployment of the compensation zone 16 and reduces the deterioration of the edges connecting the faces 26 and 28. This cutout 34 is even necessary when the faces 26 and 28 are trapezoidal to obtain a shape box inverted truncated pyramidal

Le four à micro-ondes est mis en service pendant la durée préconisée, ce qui provoque l'éclatement des grains de maïs et la transformation des sucres.The microwave oven is put into operation for the recommended time, which causes the bursting of corn kernels and the transformation of sugars.

Le dispositif est alors rempli de pop-corn prêt à la dégustation.The device is then filled with popcorn ready for tasting.

Le volume du contenant est établi en fonction du volume de grains contenu initialement dans la base.The volume of the container is established according to the volume of grains initially contained in the base.

Le consommateur peut utiliser les languettes 38 pour manipuler le dispositif sans se brûler.The consumer can use the tabs 38 to manipulate the device without getting burned.

Le consommateur ouvre à sa convenance les deux volets 46, 48 en écartant les deux oreilles 50, 52 pour piocher dans le volume intérieur.The consumer opens at its convenience the two flaps 46, 48 by spreading the two ears 50, 52 to draw in the interior volume.

On constate que le contenant est stable, rigide et permet non seulement la conservation préalable sous forme de volume réduit, la cuisson mais aussi la présentation, sans qu'il y ait besoin de déchirer ou de découper une poche avec les aléas que cela représente de renverser l'ensemble du contenu.It is found that the container is stable, rigid and allows not only the preliminary storage in the form of reduced volume, the cooking but also the presentation, without the need to tear or cut a pocket with the hazards that it represents to reverse all content.

De plus, avantage important qui solutionne le problème de la chaleur résiduelle, les fentes ménagées dans les différentes faces permettent une évacuation de la vapeur d'eau et évite la concentration de cette chaleur résiduelle.In addition, important advantage that solves the problem of residual heat, the slots in the different faces allow evacuation of water vapor and avoids the concentration of this residual heat.

On remarque aussi qu'il est possible de refermer les deux volets 46 et 48 pour conserver les pop-corn restant en vue d'une consommation ultérieure.Note also that it is possible to close the two shutters 46 and 48 to keep the remaining popcorn for later consumption.

Un tel dispositif est intéressant industriellement pour sa fabrication simpleSuch a device is industrially interesting for its simple manufacture

En effet, le dispositif selon l'invention est parfaitement rigide en lui-même.Indeed, the device according to the invention is perfectly rigid in itself.

Le pliage, le remplissage et l'emballage du dispositif selon la présente invention peuvent être aisément automatisés.The folding, filling and packaging of the device according to the present invention can be easily automated.

Le carton a été mentionné car il s'agit d'un matériau particulièrement adapté mais on pourrait utiliser un matériau de synthèse, une des conditions étant de présenter une certaine rigidité.Cardboard was mentioned because it is a particularly suitable material but one could use a synthetic material, one of the conditions being to have a certain rigidity.

De même, la forme présentée est de dimensions constantes sur la hauteur mais le contenant peut être de forme pyramidale tronquée inversée.Likewise, the shape presented is of constant size over the height, but the container may be of inverted truncated pyramidal shape.

Selon un perfectionnement les volets 46 et 48 peuvent être rendus détachables, à l'aide d'une prédécoupe pour assurer une ouverture totalement dégagée.According to an improvement flaps 46 and 48 can be made detachable, using a pre-cut to ensure a fully open opening.

Sur les figures 3, 4, 5, 6A, 6B, 7A et 7B, on a représenté différents modes de réalisation du bac 62.On the Figures 3, 4, 5 , 6A, 6B, 7A and 7B various embodiments of the tray 62 are shown.

Selon un premier mode de réalisation, le bac est obtenu à partir d'un flan 64 en forme de quadrilatère, constitué de préférence d'un multi-couches à base de papier ou carton revêtu d'au moins une feuille métallisée 66, représentée hachurée, susceptible d'absorber l'énergie transportée par les micro-ondes.According to a first embodiment, the tray is obtained from a blank 64 in the form of a quadrilateral, preferably consisting of a multi-layer based paper or cardboard coated with at least one metallized sheet 66, shown hatched , capable of absorbing the energy carried by the microwaves.

Le flan 64 comprend quatre lignes de pliage 68, chacune parallèle à un bord du flan 64, délimitant des rabats 70 susceptibles de constituer les parois latérales du bac. Les lignes de pliage 68 délimitent au centre le fond du bac dont les dimensions sont adaptées à la base 14.The blank 64 comprises four fold lines 68, each parallel to an edge of the blank 64, defining flaps 70 which can form the side walls of the tray. The fold lines 68 define in the center the bottom of the tray whose dimensions are adapted to the base 14.

Au niveau de chaque angle, une ligne de pliage 72 est prévue reliant chaque angle du flan et le point d' intersection correspondant des lignes de pliage 68 pour permettre le pliage des parois latérales du bac. De préférence, les zones 74 de surépaisseur, produites par le pliage des parois latérales au niveau de chaque angle, sont rabattues contre les faces extérieures desdites parois latérales, comme illustré en détail sur la figure 4, de manière à former une gouttière s'écoulant en direction de l'intérieur du bac 62 pour limiter les fuites de matière grasse en dehors dudit bac 62.At each corner, a fold line 72 is provided connecting each corner of the blank and the corresponding point of intersection of the fold lines 68 to allow folding of the side walls of the tray. Preferably, the zones 74 of extra thickness, produced by the folding of the side walls at each angle, are folded against the outer faces of said side walls, as illustrated in detail on the figure 4 , so as to form a gutter flowing towards the interior of the tray 62 to limit fat leakage outside said tray 62.

De préférence, comme illustré sur la figure 3, la feuille métallisée 66 est disposée entre deux lignes de pliage 68 parallèles, pour ne pas avoir au niveau des angles, des zones métallisées en contact et limiter les risques d'échauffement.Preferably, as illustrated on the figure 3 , the metallized sheet 66 is disposed between two fold lines 68 parallel, to not have at the corners, metallized areas in contact and limit the risk of overheating.

Selon une autre caractéristique de l'invention, comme illustré par la figure 5, les rabats 70 formant les parois latérales du bac comprennent chacun un prolongement 76 susceptible de recouvrir une partie ou la totalité des parois intérieures de la boîte 10 afin de réduire les risques de contact de la matière grasse avec les parois de ladite boîte 10.According to another characteristic of the invention, as illustrated by the figure 5 , the flaps 70 forming the side walls of the tray each comprise an extension 76 capable of covering part or all of the inner walls of the box 10 to reduce the risk of contact of the fat with the walls of said box 10.

Selon une autre caractéristique, le bac comprend un élément formant couvercle pour isoler les produits alimentaires, soit sous forme d'un film, ou soit sous forme d'une feuille 78 de recouvrement en carton ou en matériau semi-rigide, relié aux parois latérales de la barquette 62 à l'aide d'une soudure ou colle de préférence thermofusible, comme illustré sur les figures 6A, 6B, 7A et 7B.According to another feature, the tray comprises a lid member for isolating the food products, either in the form of a film, or in the form of a cardboard cover sheet 78 or semi-rigid material, connected to the side walls of the tray 62 using a weld or glue, preferably hot-melt, as illustrated in FIGS. FIGS. 6A, 6B, 7A and 7B .

Avantageusement, la feuille 78 de recouvrement a une forme en croix et comprend des décrochements 80 pour ne pas recouvrir les zones d'angle du flan 64 et éviter les surépaisseurs dans cette zone de pliage. De préférence, la feuille 78 comprend des premières lignes de pliage 82 parallèles aux lignes de pliage 68, légèrement décalées vers l'extérieur pour faciliter la mise en forme du bac 62.Advantageously, the cover sheet 78 has a cross shape and includes recesses 80 so as not to cover the corner areas of the blank 64 and avoid the extra thicknesses in this fold zone. Preferably, the sheet 78 comprises first fold lines 82 parallel to the fold lines 68, slightly outwardly offset to facilitate the shaping of the tray 62.

La feuille 78 de recouvrement comprend avantageusement des deuxièmes lignes de pliage permettant d'obtenir un volume susceptible de contenir les produits alimentaires, comme illustré sur la figure 6B. Les deuxièmes lignes de pliage permettent d'obtenir une forme en pyramide tronquée et comprennent des lignes de pliage délimitant un carré 84 et des lignes de pliage 86 en diagonale reliant chaque sommet dudit carré à l'angle du décrochement 80 correspondant.The covering sheet 78 advantageously comprises second fold lines making it possible to obtain a volume that can contain the food products, as illustrated in FIG. Figure 6B . The second fold lines make it possible to obtain a truncated pyramid shape and comprise fold lines delimiting a square 84 and diagonal folding lines 86 connecting each vertex of said square to the angle of the corresponding recess 80.

Selon une autre caractéristique de l'invention, illustrée par les figures 7A et 7B, la feuille 78 de recouvrement comprend des troisièmes lignes de pliage 88, non parallèles aux premières lignes de pliage 82, formant avec l'un des côtés du carré 84 un triangle tronqué. Ces lignes de pliage 88 permettent lorsqu'on tend à rapprocher les côtés opposés du bac 62 de former une goulotte de remplissage comme illustré sur la figure 7B.According to another characteristic of the invention, illustrated by the Figures 7A and 7B , the covering sheet 78 comprises third fold lines 88, not parallel to the first fold lines 82, forming with one of the sides of the square 84 a truncated triangle. These fold lines 88 make it possible, when tending to bring the opposite sides of the tray 62 together, together to form a filler neck as shown in FIG. Figure 7B .

Bien entendu, le mode de réalisation des figures 6A et 6B peut comprendre des prolongements 76 tels qu'illustrés sur la figure 5 et/ou une feuille métallisée 66 telle qu'illustrée sur la figure 3.Of course, the embodiment of the Figures 6A and 6B may include extensions 76 as illustrated on the figure 5 and / or a metallized sheet 66 as illustrated on the figure 3 .

Sur les figures 8A et 8B, on a représenté un autre mode de conditionnement des produits alimentaires. Ce mode de conditionnement comprend un sachet 90 reposant sur une feuille 92, en matériau identique à celui du flan 64, recouvrant le fond de la boîte. Le sachet 90 comprend des lignes de soudure, une 94 orientée vers le haut, thermofusible à la température de cuisson du pop-corn de manière à se dessouder lors de la cuisson et à se plaquer contre les parois intérieures de la boîte pour réduire les risques de contact de la matière grasse avec les parois de ladite boîte 10, comme illustré sur la figure 8B.On the Figures 8A and 8B there is shown another mode of packaging of food products. This mode of packaging comprises a bag 90 resting on a sheet 92, of material identical to that of the blank 64, covering the bottom of the box. The bag 90 includes weld lines, an upwardly facing 94, hot melt at the baking temperature of the popcorn so as to desolder during cooking and to press against the interior walls of the can to reduce the risks. contacting the fat with the walls of said box 10, as illustrated in FIG. Figure 8B .
