Description

L'invention se rapporte à un emballage d'un produit alimentaire portionnable P. Cet emballage peut être obtenu à partir d'un flan livré à plat et destiné à être mis en volume pour la constitution de l'emballage. Le flan peut être en une ou plusieurs parties, de préférence deux parties.The invention relates to a packaging of a food product P poritable. This package can be obtained from a blank delivered flat and intended to be volume for the constitution of the packaging. The blank may be in one or more parts, preferably two parts.

Dans la description qui suit, on entend par produit alimentaire portionnable, les produits pouvant être portionnés à froid ou à chaud, tels que les pâtes de fromages fondus, le beurre, le chocolat, les rillettes, etc.In the following description, portible food product, the products that can be portioned cold or hot, such as cheese pasta, butter, chocolate, rillettes, etc..

Un emballage de tels produits est connu depuis de nombreuses années, par exemple de US 2003/0017237 et EP 1074485 .A package of such products has been known for many years, for example US 2003/0017237 and EP 1074485 .

Pour les produits portionnables à froid, tels que le beurre, on utilise un papier métallisé que l'on plie autour de la portion de produit.For cold portionable products, such as butter, a metallized paper is used which is folded around the portion of product.

Cet emballage n'est pas étanche puisqu'il est simplement plié. Les risques de contamination sont donc importants et la date limite d'utilisation (DLU) doit être calculée en conséquence. En outre, lors de la réalisation de l'emballage, du produit peut sortir par les plis et souiller l'outil de production. Généralement, lorsqu'un utilisateur ouvre un paquet de beurre ou une portion individuelle de beurre, il s'aperçoit que du beurre se trouve dans les plis et il doit faire attention pour ne pas se salir.This packaging is not waterproof since it is simply folded. The risks of contamination are therefore significant and the expiry date (DLU) must be calculated accordingly. In addition, during the realization of the packaging, the product can come out by the folds and contaminate the production tool. Generally, when a user opens a packet of butter or a single serving of butter, he finds that butter is in the folds and he must be careful not to get dirty.

Pour les produits portionnables à chaud, il est essentiel que l'emballage soit étanche. En effet, ces produits présentent, généralement, une fluidité importante à chaud, supérieure à leur fluidité à froid. Ainsi, si l'emballage n'était pas étanche, le produit coulerait immédiatement hors de l'emballage lors de la fabrication.For hot-swab products, it is essential that the packaging is waterproof. Indeed, these products have, generally, a significant fluidity when hot, higher than their cold fluidity. Thus, if the packaging was not waterproof, the product would immediately flow out of the packaging during manufacture.

On connait les emballages en matériau thermoplastique ou thermodurcissable, chauffés pour être thermoformés et scellés. Par exemple, de tels emballages sont utilisés pour les produits P'tit Louis® ou Saint Moret®. Ces emballages sont très coûteux. En outre, il génère un encombrement important puisqu'ils conservent leur forme après usage. Il est donc nécessaire de les broyer pour diminuer leur encombrement. Enfin, le démoulage du produit peut être difficile si l'ouverture n'est pas localisée au milieu du produit, comme pour les produits P'tit Louis®. Ces emballages sont donc généralement réservés à des produits en barquette que l'on découpe au couteau dans la barquette elle-même (Saint Moret®).Thermoplastic or thermosetting packaging is known, heated to be thermoformed and sealed. For example, such packages are used for P'tit Louis® or Saint Moret® products. These packages are very expensive. In addition, it generates a large size since they retain their shape after use. It is therefore necessary to grind to reduce their size. Finally, demolding of the product can be difficult if the opening is not localized in the middle of the product, as for P'tit Louis® products. These packages are therefore generally reserved for products in trays that are cut with a knife in the tray itself (Saint Moret®).

On connait également les emballages en aluminium laqué utilisés pour des portions de fromages fondus sous forme triangulaire tels que le produit décrit dans le document de brevet WO00/17064 . Ces emballages présentent l'avantage d'être très économiques.Lacquered aluminum packaging used for triangular shaped portions of processed cheese such as the product described in the patent document is also known. WO00 / 17064 . These packages have the advantage of being very economical.

Cet emballage comprend un réceptacle comprenant un fond et des bords latéraux. Il est obtenu à partir d'un flan livré à plat et mis en volume dans un moule de maintien. Il n'est pas thermoformé, mais simplement maintenu dans cette conformation.This package comprises a receptacle comprising a bottom and side edges. It is obtained from a blank delivered flat and put in volume in a holding mold. It is not thermoformed, but simply maintained in this conformation.

La pâte de fromage fondue est coulée à chaud dans le réceptacle. Puis une feuille de couverture en aluminium laqué est déposée sur le produit encore chaud et une partie des parois latérales est repliée sur une partie de la feuille de couverture. Celle-ci est donc prise entre le produit lui-même et la partie pliée des parois latérales.The melted cheese paste is hot-poured into the receptacle. Then a lacquered aluminum cover sheet is deposited on the still hot product and part of the side walls is folded over a portion of the cover sheet. This is therefore taken between the product itself and the folded portion of the side walls.

Les parois latérales sont scellées sur la feuille de couverture en appliquant une pression et en chauffant pour sceller la laque.The sidewalls are sealed on the cover sheet by applying pressure and heating to seal the lacquer.

Cet emballage présente de nombreux inconvénients.This package has many disadvantages.

Il ne peut être utilisé qu'avec des produits portionnables à chaud. En effet, la pression appliquée lors du scellage ne peut être trop importante puisqu'elle est appliquée indirectement sur le produit lui-même. La température du produit est donc utilisée pour favoriser le scellage de la laque. Un produit portionnable à froid ne peut donc pas participer au scellage. Parallèlement, il est nécessaire de faire attention que la température du fer de scellage ne nuise pas à l'intégrité du produit.It can only be used with hot-swatch products. Indeed, the pressure applied during sealing can not be too important since it is applied indirectly to the product itself. The temperature of the product is therefore used to promote the sealing of the lacquer. A cold portionable product can not participate in sealing. At the same time, it is necessary to be careful that the temperature of the sealing iron does not affect the integrity of the product.

Par ailleurs, l'utilisation d'un tel emballage est peu pratique et l'utilisateur se salit très souvent les doigts en ouvrant l'emballage et en retirant le produit pour le consommer.Moreover, the use of such a package is impractical and the user very often gets dirty fingers opening the package and removing the product for consumption.

D'autre part, dans les coins de l'emballage, les parois latérales ne sont pas parfaitement scellées sur la feuille de couverture. En effet, dans les angles de l'emballage, deux parois latérales se chevauchent sur la feuille de couverture. Le scellage s'effectue donc mal entre la feuille et la paroi latérale immédiatement en contact avec elle.On the other hand, in the corners of the package, the side walls are not perfectly sealed on the cover sheet. In Indeed, in the corners of the package, two side walls overlap on the cover sheet. Sealing is therefore poor between the sheet and the side wall immediately in contact with it.

En outre, le formage de la feuille en coquille génère de très fortes contraintes au sein de l'aluminium laqué qui présente, de ce fait, de nombreuses microfissures. L'emballage n'est donc pas parfaitement étanche et le risque de contamination est important.In addition, the forming of the shell sheet generates very high stresses in the lacquered aluminum, which therefore has numerous microcracks. The packaging is not perfectly waterproof and the risk of contamination is important.

D'autre part, l'aluminium ne présente qu'une faible résistance mécanique, de sorte qu'il est fréquent que, par inadvertance, l'utilisateur écrase l'emballage et l'éclate.On the other hand, aluminum has only a low mechanical strength, so it is common that inadvertently the user crushes the package and bursts.

Enfin, le flan nécessaire à la réalisation de cet emballage présente de nombreuses découpes qui engendrent des pertes importantes de matériau.Finally, the blank required for the production of this packaging has many cutouts that cause significant losses of material.

Une solution à ces problèmes d'étanchéité et de résistance mécanique a été de proposer un emballage de forme similaire (même forme de flan), mais en matériau thermo-formé. Cet emballage reste donc cher, encombrant, et réservé à des produits portionnables à chaud. En outre, le démoulage du produit est difficile.One solution to these sealing and mechanical strength problems has been to provide a package of similar shape (same form of blank), but in thermo-formed material. This packaging therefore remains expensive, cumbersome, and reserved for products portionnables hot. In addition, demolding of the product is difficult.

L'invention a donc pour objectif de proposer un emballage peu encombrant après utilisation, économique et d'usage pratique, évitant à l'utilisateur de se salir les doigts lors de l'ouverture et de la saisie du produit.The invention therefore aims to provide a compact packaging after use, economic and practical use, avoiding the user to get dirty fingers when opening and entering the product.

Un autre objectif de l'invention est de proposer un emballage peu encombrant après utilisation, économique, d'usage pratique et polyvalent, c'est-à-dire pouvant être utilisé pour un produit alimentaire portionnable à chaud ou à froid.Another object of the invention is to provide a compact packaging after use, economical, practical and versatile, that is to say, can be used for a food product portionable hot or cold.

Un autre objectif de l'invention est de proposer un emballage peu encombrant après utilisation, économique, polyvalent, d'usage pratique et présentant une étanchéité optimale, y compris dans les angles et dans les plis de l'emballage.Another object of the invention is to provide a compact packaging after use, economical, versatile, practical use and having an optimal seal, including in the corners and in the folds of the package.

A cette fin, l'invention propose de réaliser un emballage à partir d'un flan en matériau pliable, dont l'agencement permet scellage étanche sur tous les bords, et permettant d'appliquer une température et une pression de scellage en dehors du produit.To this end, the invention proposes to produce a package from a foldable material blank, whose arrangement allows sealing sealed on all edges, and to apply a temperature and sealing pressure outside the product.

Plus précisément, l'invention a pour objet un emballage pliable d'un produit alimentaire portionnable, comprenant, en référence à l'emballage mis en volume :

  • un bandeau latéral, présentant deux bords longitudinaux reliés par deux bords d'extrémité, et présentant au moins une courbure et/ou un pli pour ménager un espace de stockage du produit alimentaire,
  • un opercule, présentant une zone de fond et une zone de couvercle fixées chacune sur un bord longitudinal distinct, et une zone de bordure latérale fixée sur les bords d'extrémité du bandeau de manière à enfermer le produit alimentaire dans l'espace de stockage,
l'opercule étant fixé de manière pelable sur les bords d'extrémité, sur tout un premier bord longitudinal et sur au moins une partie du deuxième bord longitudinal.More specifically, the subject of the invention is a foldable packaging of a portible food product, comprising, with reference to the packaging put in volume:
  • a lateral strip, having two longitudinal edges connected by two end edges, and having at least one curvature and / or a fold to provide a storage space for the food product,
  • a lid, having a bottom area and a lid area each attached to a distinct longitudinal edge, and a side edge area attached to the end edges of the strip so as to enclose the food product in the storage space,
the cover being peelably attached to the end edges over a first longitudinal edge and at least a portion of the second longitudinal edge.

Un emballage pliable s'oppose à un emballage thermoformé. Un emballage pliable est réalisé à partir d'un ou plusieurs flans plans, comprenant des lignes de pliage et/ou des découpes, et/ou des lignes de michaire. Ce ou ces flans plans sont ensuite mis en volume par pliage pour réaliser l'emballage.A foldable package opposes a thermoformed package. A foldable package is made from one or more flat blanks, including fold lines and / or cutouts, and / or michaire lines. This or these flat blanks are then volume folded to achieve packaging.

Au contraire, un emballage thermoformé est réalisé à partir d'une feuille en matériau thermo formable chauffé et mis en volume dans un moule.In contrast, a thermoformed packaging is made from a sheet of thermoformable material heated and placed in volume in a mold.

Un emballage de produit alimentaire est constitué par des structures de matériau(x) et d'épaisseur(s) leur permettant d'être ouvert à la main (par dépliage ou par déchirage). Par exemple, un tel emballage peut être constitué de feuilles d'aluminium de moins de 50 µm d'épaisseur, de feuilles de papier ou de carton d'un grammage inférieur à 450 gramme par mètre carré, de feuilles de polypropylène, de polyéthylène, ou de polyester de moins de 100 µm d'épaisseur.A food product package consists of material structures (x) and thickness (s) allowing them to be opened by hand (by unfolding or tearing). For example, such a package may consist of aluminum sheets less than 50 μm thick, sheets of paper or cardboard with a basis weight of less than 450 grams per square meter, polypropylene sheets, polyethylene, or polyester less than 100 μm thick.

Le terme « latéral » désigne le fait que lorsque le fond de l'emballage mis en volume est posé sur un support, le bandeau et la zone de bordure de l'opercule délimitent latéralement l'emballage.The term "lateral" refers to the fact that when the bottom of the volume packaging is placed on a support, the strip and the border area of the lid laterally delimit the package.

Le bandeau latéral est destiné à être saisi par un utilisateur pour tenir le produit alimentaire, alors que l'opercule est destiné à être pelé et éliminé (même s'il peut rester solidaire du bandeau). Ce bandeau présente la forme d'une bande plane lorsqu'il est à plat. En d'autres termes, le bandeau présente une longueur selon un axe longitudinal plus grande que la largeur selon l'axe transversal.The lateral strip is intended to be gripped by a user to hold the food product, while the lid is intended to be peeled and eliminated (even if it can remain attached to the headband). This band has the shape of a flat band when it is flat. In other words, the strip has a length along a longitudinal axis greater than the width along the transverse axis.

De préférence, la forme du bandeau à plat est sensiblement rectangulaire, c'est-à-dire qu'elle présente des bords longitudinaux plus longs que des bords d'extrémité. Une forme « sensiblement » rectangulaire est une forme présentant deux bords longitudinaux plus longs que les bords d'extrémité, tous ces bords pouvant être rectilignes ou présenter une ou plusieurs courbes ou arêtes. Le terme « sensiblement rectangulaire » couvre également une forme trapézoïdale du bandeau (l'un des bords d'extrémité est plus étroit que le deuxième bord d'extrémité ou le centre du bandeau).Preferably, the shape of the flat strip is substantially rectangular, that is, it has longitudinal edges longer than end edges. A "substantially" rectangular shape is a shape having two longitudinal edges longer than the end edges, all these edges being rectilinear or have one or more curves or edges. The term "substantially rectangular" also covers a trapezoidal shape of the headband (one of the end edges is narrower than the second end edge or the center of the headband).

De même, les bords d'extrémité peuvent être réduits à un simple point, de sorte que les deux bords longitudinaux sont sécants à l'extrémité du bandeau. En d'autres termes, le bandeau présente, aux extrémités, une forme de pointe dont les côtés sont constitués par au moins une partie des bords longitudinaux, et le sommet est constitué par un bord d'extrémité ponctuel. Dans cette configuration, la zone de bordure latérale de l'opercule est réduite à une simple ligne de pliage.Similarly, the end edges can be reduced to a single point, so that the two longitudinal edges are intersecting at the end of the strip. In other words, the strip has, at the ends, a tip shape whose sides are constituted by at least a portion of the longitudinal edges, and the top is constituted by a punctual end edge. In this configuration, the lateral border zone of the lid is reduced to a simple fold line.

Lorsque l'emballage est mis en volume, le bandeau est conformé pour présenter une courbure et/ou un pli. Autrement dit, le bandeau présente, en volume, au moins deux plans, voire une infinité de plans si le bandeau est courbé.When the package is set volume, the strip is shaped to have a curvature and / or a fold. In other words, the band has, in volume, at least two planes, or even an infinity of planes if the band is curved.

On entend par « pelable », une fixation étanche, par collage ou scellage, permettant de séparer manuellement, lors d'une utilisation normale de l'emballage, les deux pièces ainsi fixées sans les déchirer.By "peelable" is meant a sealed fastening, by gluing or sealing, allowing manual separation, during normal use of the package, of the two pieces thus fixed without tearing them.

Un mode de réalisation préféré d'un emballage selon l'invention est illustré aux figures 1 à 26. Les figures 1a, 1b et 1c illustrent des variantes de formes de bandeaux.A preferred embodiment of a package according to the invention is illustrated in Figures 1 to 26 . The Figures 1a, 1b and 1c illustrate variants of banner shapes.

Selon une première forme illustrée aux figures 1 à 9, l'emballage pliable selon l'invention comprend, par référence à l'emballage mis en volume :

  • un bandeau latéral 400 destiné à être saisi par l'utilisateur et présentant deux bords longitudinaux 401 et 402, reliés par deux bords d'extrémité 403 et 404 ; et
  • un opercule 500 présentant une zone de fond 501, une zone de couvercle 502 et une zone de bordure latérale 503.
In a first form illustrated in Figures 1 to 9 , the foldable package according to the invention comprises, with reference to the packaging put in volume:
  • a lateral strip 400 intended to be grasped by the user and having two longitudinal edges 401 and 402, connected by two end edges 403 and 404; and
  • a cover 500 having a bottom area 501, a cover area 502 and a side edge area 503.

Dans la variante illustrée en figure 1, les bords d'extrémité 403 et 404 du bandeau 400 sont courbes.In the variant illustrated in figure 1 the end edges 403 and 404 of the strip 400 are curved.

Le bandeau latéral 400 présente une ligne de pliage 405 s'étendant parallèlement aux bords d'extrémité et aux deux bords longitudinaux de manière à ménager au moins deux aplats de fixation non coplanaires.The lateral strip 400 has a fold line 405 extending parallel to the end edges and to the two longitudinal edges so as to provide at least two non-coplanar fastening areas.

Dans le bandeau 410 de la figure 1a, une ligne de pliage 411 est prévue sensiblement au milieu du bandeau. Cette ligne de pliage 411 est destinée à être disposée entre les deux pointes (en haut et en bas) de l'opercule (voir figure 2). En outre, le bandeau 410 comprend deux découpes 412 joignant un bord longitudinal, respectivement 401-402, à la ligne de pliage 405 et séparant, lorsque l'emballage est mis en volume, deux aplats de fixation 416-417 et 418-419 (voir figure 2).In the banner 410 of the figure 1a a fold line 411 is provided substantially in the middle of the strip. This fold line 411 is intended to be arranged between the two points (at the top and at the bottom) of the lid (see figure 2 ). In addition, the strip 410 comprises two cutouts 412 joining a longitudinal edge, respectively 401-402, to the fold line 405 and separating, when the package is set in volume, two flat areas 416-417 and 418-419 ( see figure 2 ).

Le bandeau 420 de la figures 1b présente une zone de collage 421 délimitée par deux plis 422 et 423. La zone de collage 421 comprend également un pli 424 séparant ladite zone en deux portions complémentaires destinées à être collées l'une sur l'autre, pour constituer une patte de préhension. La figure 2a illustre ce bandeau 420 mis en volume. La patte de préhension 425 peut être saisie entre les deux doigts de l'utilisateur.The banner 420 of the figures 1b has a bonding area 421 delimited by two folds 422 and 423. The bonding area 421 also comprises a fold 424 separating said area into two complementary portions to be glued to one another, to form a gripping tab. The figure 2a illustrates this headband 420 set volume. The gripping tab 425 can be grasped between the two fingers of the user.

Le bandeau latéral 430 de la figure 1c présente deux bords longitudinaux 431-432 présentant deux courbes. En outre, le bandeau 430 présente deux bords d'extrémité 433-434 rectilignes.The lateral band 430 of the figure 1c has two longitudinal edges 431-432 having two curves. In addition, the strip 430 has two straight end edges 433-434.

La figure 2 illustre le bandeau de la figure 1 a mis en volume au-dessus de l'opercule 500. Pour former l'emballage, le bandeau 410 est plié de telle sorte qu'il présente un pli pour ménager un espace de stockage du produit alimentaire. Ensuite, un bord longitudinal est déposé en périphérie de la zone de fond 501 de l'opercule 500. Dans le mode de réalisation illustré, les bords longitudinaux présentent des aplats de fixation 416-417, 418-419. Ce sont donc ces aplats qui sont déposés en périphérie de la zone de fond 501 de l'opercule 500.The figure 2 illustrates the banner of the figure 1 has formed volume over the operculum 500. To form the package, the strip 410 is folded so that it has a fold to provide a storage space of the food product. Then, a longitudinal edge is deposited at the periphery of the bottom zone 501 of the cap 500. In the illustrated embodiment, the longitudinal edges have flat areas 416-417, 418-419. It is therefore these areas which are deposited at the periphery of the bottom zone 501 of the cover 500.

Ensuite, on fixe de manière pelable, par collage ou scellage, le premier bord longitudinal du bandeau et la zone de fond de l'opercule. Lorsque le bandeau porte des aplats de fixation, ce sont eux qui sont fixés à l'opercule. Le résultat est illustré en figure 3.Next, the first longitudinal edge of the strip and the bottom zone of the cap are peelably secured by gluing or sealing. When the headband has solid areas of fixation, it is they who are fixed to the operculum. The result is illustrated in figure 3 .

Ensuite, on rabat partiellement l'opercule 500 et on fixe de manière pelable les deux bords d'extrémité du bandeau sur la zone de bordure latérale 503 de l'opercule 500. Ainsi, on ferme latéralement l'espace de stockage. Il est alors possible de disposer le produit alimentaire P sur la zone de fond 501, entre le bandeau latéral et la zone de bordure latérale de l'opercule.Then, the lid 500 is partially folded and the two end edges of the strip are peelably fixed to the lateral edge region 503 of the lid 500. Thus, the storage space is closed laterally. It is then possible to dispose the food product P on the bottom zone 501, between the lateral strip and the lateral border zone of the lid.

Une fois le produit P déposé dans l'espace de stockage, la zone de couvercle 502 est rabattue et fixée de manière pelable sur au moins une partie du deuxième bord longitudinal du bandeau situé dans le prolongement des bords d'extrémité (figure 4). Le résultat est illustré en figure 5 qui représente l'emballage fermé. De cette manière, lorsque l'utilisateur ouvre l'emballage, il peut arracher l'opercule sur un bord longitudinal complet, sur les deux bords d'extrémité et sur une partie, au moins, du deuxième bord longitudinal (voir figures 6 à 8).Once the product P has been deposited in the storage space, the cover area 502 is folded down and peelably attached to at least a portion of the second longitudinal edge of the strip located in the extension of the end edges ( figure 4 ). The result is illustrated in figure 5 which represents the closed package. In this way, when the user opens the package, it can tear the lid on a full longitudinal edge, on both end edges and on at least part of the second longitudinal edge (see Figures 6 to 8 ).

Lorsque l'utilisateur veut consommer le produit P, il saisit l'emballage selon l'invention en plaçant ses doigts sur les parois latérales formée par le bandeau latéral 410 selon l'invention. La zone de couvercle 502 étant fixé de manière pelable sur les aplats de fixation 416-417, l'utilisateur peut désolidariser la zone de couvercle 502 des parois latérales du bandeau. Pour cela, comme illustré en figure 6, il saisit une extrémité de l'opercule et soulève l'opercule 502 selon le sens de la flèche F3.When the user wants to consume the product P, he grasps the packaging according to the invention by placing his fingers on the side walls formed by the lateral strip 410 according to the invention. Since the cover area 502 is peelably attached to the fastening areas 416-417, the user can separate the cover area 502 from the side walls of the strip. For this, as illustrated in figure 6 he grasps one end of the lid and raises the lid 502 in the direction of the arrow F3.

Cette extrémité de la zone de couvercle peut porter une languette de tirage pour faciliter la saisie et l'ouverture. On distingue une telle languette de tirage selon l'invention, d'un tircelle (ou bande d'ouverture facile) de l'état de la technique en ce que la languette ne déchire pas l'emballage et, en particulier la zone de couvercle, mais reste solidaire de cette zone. Ainsi, grâce à la languette de tirage et à la fixation pelable (donc non déchirable), l'utilisateur sépare deux parties de l'emballage le long d'une zone de fixation entre ces deux parties, mais ne les déchire pas, ces parties conservant leur intégrité.This end of the lid area may carry a pull tab to facilitate grasping and opening. One distinguishes such a pull tab according to the invention, a tircelle (or easy opening strip) of the state of the art in that the tongue does not tear the packaging and, in particular the lid area but remains in solidarity with this area. Thus, thanks to the pull tab and the peelable attachment (thus not tearable), the user separates two parts of the package along a fastening area between these two parts, but do not tear them apart, these parts preserving their integrity.

En outre la languette de tirage selon l'invention est localisée sur une partie réduite de l'emballage, et fait, de préférence, partie intégrante de l'emballage. Au contraire, le tircelle doit être rapporté sur l'emballage et disposé tout le long de la zone que l'on souhaite déchirer. Dès que le tircelle s'arrête, le déchirage cesse. Les tircelles sont coûteux, compte-tenu de leur étendue, et doivent être positionnés avec précision, rendant la fabrication coûteuse et délicate.In addition, the pull tab according to the invention is located on a reduced portion of the package, and is preferably an integral part of the package. On the contrary, the tircelle must be attached to the package and placed all along the area that is desired to tear. As soon as the tircelle stops, the tearing stops. Tircelles are expensive, given their extent, and must be positioned precisely, making the manufacturing expensive and delicate.

L'utilisateur continue d'ouvrir l'emballage selon l'invention en tirant la zone de couvercle 502 selon la flèche F5 (figure 7). A ce stade, la zone de bordure latérale 503 reliée à la zone de couvercle 502 est désolidarisée des deux bords d'extrémités 403-404 du bandeau latéral 410,The user continues to open the package according to the invention by pulling the lid area 502 according to the arrow F5 ( figure 7 ). At this stage, the lateral edge zone 503 connected to the cover zone 502 is separated from the two end edges 403-404 of the lateral strip 410,

Selon l'invention, l'utilisateur continue son mouvement d'ouverture selon la flèche F6 (figure 8), en séparant au moins une partie de la zone de fond 501 du bandeau latérale 410.According to the invention, the user continues his opening movement according to the arrow F6 ( figure 8 ), separating at least a portion of the bottom zone 501 from the lateral strip 410.

De manière préférentielle, comme illustré en figure 9, le bandeau latérale 410 porte deux lignes de pliage 10 reliant les deux bords longitudinaux. Ces lignes de pliage permettent à l'utilisateur qui tient l'emballage par le bandeau, par exemple entre le pouce et l'index, d'écarter une partie de ce bandeau selon les flèches F7 et F8 pour pouvoir mettre très facilement le produit P dans sa bouche ou sur un support sans avoir à le toucher avec ses doigts.Preferably, as illustrated in figure 9 , the lateral strip 410 carries two fold lines 10 connecting the two longitudinal edges. These fold lines allow the user who holds the packaging by the headband, for example between the thumb and forefinger, to spread part of this headband according to the arrows F7 and F8 to be able to very easily put the product P in his mouth or on a stand without having to touch it with his fingers.

Ce mode de réalisation permet d'obtenir des emballages de forme triangulaire ne générant que peu de pertes lors de la fabrication. En effet, comme le montre la figure 10, les opercules 500 présentent une forme symétrique permettant de réaliser plusieurs opercules de manière emboitée sur une seule bande de matériau. Les pertes de matières L, illustrées en grisé sur la figure 10, représentent une surface beaucoup plus faible que les pertes engendrées par l'emballage décrit dans le document de brevet WO00/17064 .This embodiment makes it possible to obtain triangular-shaped packages that generate only a small amount of waste during manufacture. Indeed, as shown in figure 10 , the covers 500 have a symmetrical shape for making several covers interlocking manner on a single strip of material. Losses of L material, illustrated in gray on the figure 10 , represent a much smaller area than the losses generated by the package described in the patent document WO00 / 17064 .

Ceci est d'autant plus vrai lorsque l'opercule et le bandeau sont rectangulaires.This is especially true when the lid and the strip are rectangular.

Les figures 11 à 18 illustrent une deuxième forme possible, obtenue avec le mode de réalisation préféré de l'invention.The Figures 11 to 18 illustrate a second possible form, obtained with the preferred embodiment of the invention.

Dans la figure 11, l'opercule 600 présente une zone de fond 601 et une zone de couvercle 602 sensiblement rectangulaires. Ces zones sont reliées par une zone de bordure latérale 603 également rectangulaire. Dans cette figure 11, la zone de fond 601 et la zone de couvercle 602, présentent chacune une languette de tirage 604. Ces languettes de tirage 604 permettent d'ouvrir l'emballage soit par la zone de fond soit par la zone de couvercle, sans déchirer l'opercule. Dans ce cas, l'opercule est fixé de manière pelable sur les bords d'extrémité, sur tout le premier bord longitudinal et sur tout le deuxième bord longitudinal du bandeau 700.In the figure 11 , the lid 600 has a substantially rectangular bottom area 601 and a lid area 602. These areas are connected by a side edge zone 603 also rectangular. In this figure 11 the bottom area 601 and the cover area 602 each have a pull tab 604. These pull tabs 604 open the package either through the bottom area or through the cover area without tearing the package. cover. In this case, the cover is peelably attached to the end edges, the entire first longitudinal edge and the entire second longitudinal edge of the strip 700.

Ce bandeau 700 présente une ligne de pliage 701 s'étendant parallèlement aux bords d'extrémité 702-703 et aux deux bords longitudinaux 704-705. De cette manière, lorsque le bandeau est mis en volume, des aplats de fixation sont disposés sensiblement parallèlement à la zone de fond 601 et sensiblement perpendiculairement (c'est-à-dire à 90 degrés, plus ou moins 5 degrés près) à la partie du bandeau qui forme les parois latérales de l'emballage.This strip 700 has a fold line 701 extending parallel to the end edges 702-703 and the two longitudinal edges 704-705. In this way, when the strip is set in volume, flat areas are disposed substantially parallel to the bottom area 601 and substantially perpendicular (that is to say 90 degrees, plus or minus 5 degrees) to the part of the band that forms the side walls of the package.

Le bandeau 700 comprend également deux lignes de pliage 706-707 permettant de ménager, lorsque le bandeau latéral est mis en volume, un espace de stockage du produit alimentaire P. A l'extrémité de ces deux lignes de pliage 706-707, le bandeau présente une découpe joignant un bord longitudinal 704-705 à la ligne de pliage 701. Ces découpes 708 permettent la séparation des aplats de fixations d'un même bord longitudinal lors du pliage du bandeau. Ceci est illustré en figure 12.The strip 700 also comprises two fold lines 706-707 making it possible, when the lateral strip is set, to provide a storage space for the food product P. At the end of these two fold lines 706-707, the strip has a cut joining a longitudinal edge 704-705 to the fold line 701. These cuts 708 allow the separation of flat areas of fasteners of the same longitudinal edge during the folding of the strip. This is illustrated in figure 12 .

La figure 11a illustre une variante de bandeau 710 présentant deux bords longitudinaux 711-712 présentant chacun trois segments non alignés. Les deux bords longitudinaux 711-712 sont reliés l'un à l'autre par des bords d'extrémité 713-714 plus étroit que le centre du bandeau où les bords longitudinaux sont parallèles. Autrement dit, le bandeau présente deux trapèzes 715-716 disposés de part et d'autre d'un rectangle 717.The figure 11a illustrates an alternative strip 710 having two longitudinal edges 711-712 each having three non-aligned segments. The two longitudinal edges 711-712 are connected to each other by end edges 713-714 narrower than the center of the strip where the longitudinal edges are parallel. In other words, the strip has two trapezoids 715-716 arranged on either side of a rectangle 717.

Comme pour les figures 3 à 9, les figures 13 à 18 illustrent la mise en volume de l'emballage (figure 13), le remplissage de l'emballage par le produit alimentaire P, la fermeture de l'emballage (figures 14 et 15) et l'ouverture de l'emballage (figures 16 à 18) pour une forme d'emballage rectangulaire.As for Figures 3 to 9 , the Figures 13 to 18 illustrate the volume of the packaging ( figure 13 ), the filling of the packaging by the food product P, the closure of the packaging ( Figures 14 and 15 ) and the opening of the packaging ( Figures 16 to 18 ) for a rectangular packaging form.

Dans tous les exemples cités dans la présente description, l'opercule est fixé de manière pelable sur les deux bords d'extrémité sur tout un premier bord longitudinal et sur au moins une partie du deuxième bord longitudinal.In all the examples cited in the present description, the cap is peelably attached to both end edges over a first longitudinal edge and at least a portion of the second longitudinal edge.

Lorsque la zone de couvercle est fixée de manière pelable sur une partie seulement du deuxième bord longitudinal, l'autre partie de ce bord longitudinal est fixée fermement, c'est-à-dire sans possibilité de séparer l'opercule du bandeau le long de cette partie sans avoir à déchirer l'un et/ou l'autre.When the lid area is peelably attached to only a portion of the second longitudinal edge, the other portion of this longitudinal edge is firmly attached, i.e. without the possibility of separating the lid from the strip along this part without having to tear one and / or the other.

Néanmoins, de manière préférentielle, l'opercule est fixé de manière pelable tout le long des deux bords longitudinaux du bandeau. De cette manière, l'utilisateur peut ouvrir l'emballage selon l'invention soit par le fond soit par le couvercle de l'opercule, comme s'il pelait une banane.Nevertheless, preferably, the lid is peelably attached all along the two longitudinal edges of the strip. In this way, the user can open the package according to the invention either by the bottom or by the lid of the lid, as if it was peeling a banana.

Ce procédé d'ouverture et les caractéristiques de l'emballage qui permettent la mise en oeuvre de ce procédé, permettent d'obtenir un emballage très facile d'usage, économique à fabriquer, et très hygiénique puisque l'utilisateur ne touche jamais le produit et peut le consommer directement dans l'emballage en le mettant dans sa bouche sans l'avoir touché avec ses doigts.This opening process and the characteristics of the packaging that allow the implementation of this process, make it possible to obtain a package very easy to use, economical to manufacture, and very hygienic since the user never touches the product. and can consume it directly in the package by putting it in his mouth without having touched it with his fingers.

Les figures 19 à 20 montrent une troisième forme d'emballage semi-circulaire. Dans cette forme, le bandeau présente une courbure continue permettant de ménager un espace de stockage du produit alimentaire. Ici encore, le bandeau présente une ligne de pliage parallèle à l'ensemble de ses bords, permettant de réaliser des aplats de fixation sur la zone de fond, la zone de couvercle et la zone de bordure latérale de l'opercule 900.The Figures 19 to 20 show a third form of semicircular packaging. In this form, the strip has a continuous curvature to provide a storage space of the food product. Here again, the strip has a fold line parallel to all of its edges, making it possible to achieve flat areas of attachment to the bottom area, the cover area and the lateral edge area of the cover 900.

La quatrième forme illustrée aux figures 21 à 23 illustre un opercule 1000 présentant une zone de fond 1001 et une zone de couvercle 1002 reliées par une zone de bordure latérale 1003 réduite à une simple ligne de pliage. De manière complémentaire, le bandeau 1100 présente deux bords longitudinaux 1101-1102 présentant chacun trois segments non alignés. Les deux bords longitudinaux 1101-1102 sont reliés l'un à l'autre par des bords d'extrémité 1103 et 1104 limités, chacun, à un simple point. Autrement dit, les bords longitudinaux 1101 et 1102 sont séquents et forment deux pointes.The fourth form illustrated in Figures 21 to 23 illustrates a cover 1000 having a bottom area 1001 and a cover area 1002 connected by a side edge area 1003 reduced to a single fold line. In a complementary manner, the strip 1100 has two longitudinal edges 1101-1102 each having three non-aligned segments. The two longitudinal edges 1101-1102 are connected to each other by end edges 1103 and 1104 each limited to a single point. In other words, the longitudinal edges 1101 and 1102 are sequential and form two points.

Ainsi, lorsque l'emballage est mis en volume (figure 23), les pointes 1103 et 1104 du bandeau 1100 coïncident avec la zone de bordure latérale linéaire 1003 de l'opercule 1000. Sur la figure 22, les aplats de fixation n'ont pas été représentés par souci de clarté.Thus, when the packaging is put in volume ( figure 23 ), the tips 1103 and 1104 of the strip 1100 coincide with the linear lateral edge area 1003 of the cover 1000. On the figure 22 the flat areas have not been shown for clarity.

Pour réaliser l'emballage, on plie le bandeau 1100 comme illustré en figure 22 et on le fixe de manière pelable sur la zone de fond 1002 de l'opercule 1000. Ensuite, on remplit l'espace délimité par le bandeau et la zone de fond avec le produit P. Enfin, on rabat la zone de couvercle 1001 et on la fixe de manière pelable, au moins partiellement mais de préférence complètement, sur le bandeau 1100. L'emballage obtenu est illustré en figure 23.To make the packaging, fold the strip 1100 as illustrated in figure 22 and peelably attached to the bottom area 1002 of the seal 1000. Then, the space bounded by the strip and the bottom area is filled with the product P. Finally, the lid area 1001 is folded and it is fixed peelably, at least partially but preferably completely, on the strip 1100. The packaging obtained is illustrated in FIG. figure 23 .

Les figures 24 à 26 illustrent un emballage selon l'invention présentant une forme de berlingot, lorsqu'il est mis en volume.The Figures 24 to 26 illustrate a package according to the invention having a shape of carton, when it is put in volume.

A cette fin, l'emballage comprend un bandeau 1200 présentant deux bords longitudinaux 1201-1202, chacun constitué par deux segments non colinéaires. Ces deux bords longitudinaux 1201-1202 sont reliés par deux bords d'extrémité 1203-1204 limités à un simple point. En d'autres termes, le bandeau présente une forme de losange. L'emballage comprend également un opercule 1300 présentant une zone de fond 1301 et une zone de couvercle 1302 triangulaire reliées entre elles par une zone de bordure latérale 1303 constituée par une simple ligne de pliage. Autrement dit, l'opercule 1300 présente également une forme de losange.To this end, the package comprises a strip 1200 having two longitudinal edges 1201-1202, each consisting of two non-collinear segments. These two longitudinal edges 1201-1202 are connected by two end edges 1203-1204 limited to a single point. In other words, the band has a diamond shape. The package also comprises a lid 1300 having a bottom zone 1301 and a triangular lid zone 1302 interconnected by a zone of lateral edge 1303 constituted by a simple fold line. In other words, the lid 1300 also has a diamond shape.

Sur les figures 25 et 26, les aplats de fixation n'ont pas été illustrés par souci de clarté.On the Figures 25 and 26 the flat areas have not been illustrated for the sake of clarity.

Ainsi, lorsque l'emballage selon l'invention est mis en volume, chaque aplat de fixation est disposé sensiblement parallèlement au fond et dirigé vers l'extérieur du flan mis en volume, en saillie par rapport aux plans constitués par les parois latérales. Dans cette position, l'aplat de fixation présente une surface de fermeture (par scellage ou collage pelable) dirigée vers le haut, c'est-à-dire à l'opposé par rapport au fond. La zone de couvercle peut donc être fixée au dessus de la zone de fond, sur les aplats de fixation et en dehors du produit P.Thus, when the packaging according to the invention is set in volume, each flattening area is disposed substantially parallel to the bottom and directed outwardly of the blank set in volume, projecting from the planes formed by the side walls. In this position, the flattening surface has a sealing surface (sealing or peelable bonding) directed upwards, that is to say opposite to the bottom. The lid area can therefore be fixed above the bottom zone, on the solid areas and outside the P product.

De cette manière, lors de la fabrication, grâce à un moyen de contre-pression (non illustré) disposé sous les aplats, il est possible d'appliquer une pression de fixation importante sur le couvercle et sur les aplats de fixation. Cette pression n'est donc jamais appliquée directement ou indirectement sur le produit P contenu dans l'espace de stockage. De même, il est possible de chauffer localement l'opercule et les aplats de fixation lors de cette mise sous pression, sans risquer de chauffer le produit.In this way, during manufacture, by means of back pressure (not shown) disposed under the flat areas, it is possible to apply a significant fastening pressure on the cover and on the flat areas. This pressure is never applied directly or indirectly to the product P contained in the storage space. Similarly, it is possible to locally heat the lid and the flattening plates during this pressurization, without risking heating the product.

Cette structure de l'emballage permet donc de conditionner des produits portionnables chaud comme à froid, tels que du beurre ou de la charcuterie, tout en s'assurant d'un emballage parfaitement étanche.This packaging structure therefore makes it possible to package hot and cold portionable products, such as butter or cold cuts, while ensuring a perfectly sealed package.

En outre, les aplats de fixation servent de butée aux doigts de l'utilisateur, lors de l'ouverture de l'emballage. En effet, l'arrachage de l'opercule sur tout un premier bord longitudinal, sur les deux bords d'extrémité, et sur au moins une partie du deuxième bord longitudinal peut faire glisser l'emballage des mains de l'utilisateur. Le fait de prévoir des aplats de fixation sur un bord longitudinal, voire de préférence sur les deux bords longitudinaux, empêche l'emballage de glisser lors de l'ouverture.In addition, the flat areas serve as a stop on the fingers of the user, when opening the package. Indeed, tearing of the lid on a first longitudinal edge, on both end edges, and on at least a portion of the second longitudinal edge can slide the package of the user's hands. The fact of providing flat areas on a longitudinal edge, or preferably on both longitudinal edges, prevents the package from sliding during opening.

De manière avantageuse, l'opercule présente une rigidité inférieure au bandeau. Ainsi, lors de l'ouverture de l'emballage par l'utilisateur, le bandeau s'oppose plus aux déformations mécaniques que l'opercule.Advantageously, the lid has a lower rigidity to the strip. Thus, during the opening of the package by the user, the strip is more opposed to mechanical deformations that the lid.

Cela évite que l'emballage s'écrase dans le sac de l'utilisateur. Cela permet également de fabriquer un emballage moins coûteux tout en s'assurant que le bandeau conserve sa forme lors de l'ouverture. Ainsi, l'utilisateur peut tenir entre ses doigts le bandeau qui contient le produit alimentaire, après ouverture.This prevents the package from crashing into the user's bag. This also makes it possible to manufacture a less expensive package while ensuring that the band retains its shape when opening. Thus, the user can hold between his fingers the band that contains the food product, after opening.
