Description

La présente invention concerne un emballage du type à refermeture constitué d'une enveloppe extérieure relativement rigide et d'un sachet intérieur souple à soufflets.The present invention relates to a packaging of the reclosing type consisting of a relatively rigid outer envelope and a flexible inner bag with bellows.

On connaît déjà de nombreux emballages dont le but est d'améliorer l'étanchéité dudit emballage après le conditionnement du produit et le scellage du sachet intérieur. Le brevet US 2 463 313 concerne notamment un tel procédé, selon lequel on assure une bonne étanchéité grâce à une manière spécifique de pliage et d'application de chaleur et de pression sur le sachet intérieur. Cependant, aucun brevet publié actuellement ne mentionne le problème qui naît lors de la première ouverture d'un emballage, lorsqu'on souhaite conserver le produit ainsi disponible dans son emballage d'origine. Le problème à la base de la présente invention est donc de trouver un emballage du type à refermeture, garantissant une bonne étanchéité et imperméabilité, c'est-à-dire une bonne durée de vie du produit après ouverture de l'emballage. Il faut d'autre part disposer d'un emballage de maniement assez simple pour le consommateur et dont le prix soit suffisamment attractif par rapport à ce qui existe actuellement sur le marché. L'emballage du type à refermeture selon la présente invention permet de mettre à disposition des consommateurs un tel emballage.Numerous packages are already known, the aim of which is to improve the tightness of said packaging after packaging the product and sealing the inner bag. US Patent 2,463,313 relates in particular to such a method, according to which a good seal is ensured by a specific way of folding and of application of heat and pressure on the inner bag. However, no patent currently published mentions the problem which arises when opening a package for the first time, when it is desired to keep the product thus available in its original packaging. The problem underlying the present invention is therefore to find a packaging of the reclosing type, guaranteeing a good seal and impermeability, that is to say a good shelf life of the product after opening the packaging. On the other hand, it is necessary to have handling packaging that is fairly simple for the consumer and whose price is sufficiently attractive compared to what currently exists on the market. The packaging of the reclosing type according to the present invention makes it possible to make such packaging available to consumers.

L'invention concerne un emballage du type à refermeture constitué d'une enveloppe extérieure relativement rigide et d'un sachet intérieur souple à soufflets, solidaire de ladite enveloppe, dans lequel l'enveloppe extérieure comporte au moins un volet dont le rabattement pour la fermeture plie et pince les deux faces de l'extrémité du sachet et les deux parois latérales de l'enveloppe extérieure sont exemptes de partie mobile.The invention relates to a reclosing type packaging consisting of a relatively rigid outer envelope and a flexible inner bag with bellows, integral with said envelope, in which the outer envelope comprises at least one flap whose fold for closing folds and clamps the two sides of the end of the bag and the two side walls of the outer velvet are free from moving parts.

Par parties mobiles on entend dans la présente description, par exemple des pattes triangulaires qui permettent normalement un pliage du soufflet du sachet intérieur.By mobile parts is meant in the present description, for example triangular tabs which normally allow folding of the bellows of the inner bag.

L'emballage du type à refermeture selon l'invention trouve des applications surtout pour le conditionnement de produits alimentaires, mais est également envisageable dans d'autres secteurs industriels. Dans le domaine alimentaire, l'emballage est prévu chaque fois qu'on conditionne un produit sensible à l'air et/ou à l'humidité et/ou un produit dont la conservation de l'arôme est primordial, par exemple du café soluble ou torréfié.The reclosing type packaging according to the invention finds applications especially for the packaging of food products, but is also conceivable in other industrial sectors. In the food sector, packaging is provided each time a product sensitive to air and / or humidity is conditioned and / or a product whose preservation of the aroma is essential, for example soluble coffee or roasted.

Selon un premier mode de réalisation de l'emballage selon l'invention, l'enveloppe extérieure comporte un volet qui est dans le prolongement de la paroi dorsale de ladite enveloppe, ledit volet pliant et pinçant les deux faces de l'extrémité du sachet autour de l'arête supérieure de la paroi frontale de l'enveloppe selon un angle compris entre 90 et 180°.According to a first embodiment of the packaging according to the invention, the outer envelope comprises a flap which is in the extension of the dorsal wall of said envelope, said foldable flap and pinching the two faces of the end of the bag around from the upper edge of the front wall of the enclosure at an angle between 90 and 180 °.

Dans ce cas, on prévoit un moyen de solidarisation de la paroi dorsale et de la paroi frontale de l'enveloppe extérieure, par exemple un système d'attache du type Velcro ou tout autre moyen connu dans la technique. L'angle de pliure de l'extrémité du sachet est de préférence compris entre 110 et 150°.In this case, a means of securing the back wall and the front wall of the outer envelope is provided, for example a Velcro type fastening system or any other means known in the art. The fold angle of the end of the bag is preferably between 110 and 150 °.

Dans un second mode de réalisation de l'emballage selon l'invention, l'enveloppe comprend un volet muni d'un prolongement et un organe flexible coopérant avec le prolongement du volet pour maintenir ce dernier en position ouverte ou fermée, ledit volet pliant et pinçant les deux faces de l'extrémité du sachet selon un angle compris entre 90 et 180°. L'angle de pliure du sachet est de préférence compris entre 140 et 180°.In a second embodiment of the packaging according to the invention, the envelope comprises a flap provided with an extension and a flexible member cooperating with the extension of the flap to keep the latter in the open or closed position, said folding flap and pinching the two faces of the end of the bag at an angle between 90 and 180 °. The fold angle of the sachet is preferably between 140 and 180 °.

Selon un troisième et dernier mode de réalisation de l'emballage selon l'invention, l'enveloppe comporte une' feuille repliée sur elle-même de manière à former un volet et, en position de fermeture, un volume parallélépipédique coopérant avec un second volet formant également en position de fermeture un volume parallélépipédique, lesdits volumes parallélépipédiques coopérant entre eux pour pincer les deux faces de l'extrémité du sachet. Dans ce cas, l'extrémité du sachet est partiellement collée aux volumes parallélépipédiques de sorte que l'ouverture du volet entraîne l'ouverture du sachet.According to a third and last embodiment of the packaging according to the invention, the envelope comprises a 'sheet folded back on itself so as to form a flap and, in the closed position, a rectangular volume cooperating with a second flap also forming in the closed position a parallelepiped volume, said parallelepiped volumes cooperating with each other to pinch the two faces of the end of the bag. In this case, the end of the bag is partially glued to the rectangular volumes so that the opening of the flap causes the opening of the bag.

Le sachet intérieur est un sachet à soufflets, fabriqué à partir d'une feuille mince de 0,02 à 0,3 mm d'épaisseur. La nature de cette feuille dépend du produit à emballer: papier éventuellement enduit, matière plastique telle que polyester, métallisée le cas échéant, complexe d'aluminium etc... suivant que le sachet doit être étanche à l'humidité et/ou à l'oxygène par exemple.The inner bag is a bellows bag, made from a thin sheet of 0.02 to 0.3 mm thick. The nature of this sheet depends on the product to be packaged: possibly coated paper, plastic material such as polyester, metallized if necessary, aluminum complex, etc. depending on whether the sachet must be moisture and / or water tight. for example.

Pour la fabrication il y a généralement avantage à ce que la feuille soit thermosoudable.For manufacturing there is generally an advantage in that the sheet is heat sealable.

Par exemple, une bande est repliée longitudinalement sur elle-même et scellée bord à bord, puis scellée transversalement à une extrémité après formage des soufflets latéraux, ensuite de quoi le sachet est rempli et scellé transversalement à l'autre extrémité. Pour l'emballage selon l'invention, il est préférable que l'extrémité inférieure soit aplatie pour s'adapter au fond de l'enveloppe extérieure.For example, a strip is folded longitudinally on itself and sealed edge to edge, then sealed transversely at one end after forming the side bellows, after which the bag is filled and sealed transversely at the other end. For the packaging according to the invention, it is preferable that the lower end is flattened to adapt to the bottom of the outer envelope.

Une autre méthode de formation d'un sachet à soufflets consiste à plier longitudinalement les deux bords d'une bande sur la profondeur des soufflets, puis de plier la bande transversalement de façon à faire se rejoindre les bords latéraux à l'intérieur et à les souder ensemble. Le sachet est alors ouvert à une extrémité par laquelle il est rempli, puis cette extrémité est scellée et de préférence aplatie pour former le fond.Another method of forming a bellows sachet consists in folding the two edges of a strip longitudinally over the depth of the bellows, then folding the strip transversely so as to bring the lateral edges inside and to join them together. weld together. The bag is then opened at one end with which it is filled, then this end is sealed and preferably flattened to form the bottom.

En variante, la partie supérieure du sachet est munie d'un organe de déchirage tel qu'un fil ou une bandelette. Sinon, le sachet scellé peut être ouvert en coupant la partie supérieure.As a variant, the upper part of the bag is provided with a tearing member such as a wire or a strip. Otherwise, the sealed bag can be opened by cutting the upper part.

L'enveloppe extérieure est essentiellement constituée d'au moins une feuille relativement rigide de carton, de carton couché ou enduit, de matière plastique par exemple, de 0,4 à 1,5 mm d'épaisseur. Dans une forme d'exécution préférentielle, elle présente une base carrée ou rectangulaire et le volet de fermeture se trouve au sommet.The outer envelope essentially consists of at least one relatively rigid sheet of cardboard, coated or coated cardboard, of plastic material for example, 0.4 to 1.5 mm thick. In a preferred embodiment, it has a square or rectangular base and the closing flap is at the top.

  • La Figure 5 représente l'emballage de la Figure 4 ouvert.Figure 5 shows the packaging of Figure 4 open.

Selon la figure 1, l'enveloppe extérieure 17 entoure un sachet à soufflets 18, dans lequel se trouve le produit conditionné. Les parois latérales 19 de l'enveloppe ne comportent aucune patte de repliage. Le volet 20 prolonge la paroi dorsale 21 de l'enveloppe extérieure et vient plier et pincer les deux faces 24 de l'extrémité du sachet 18 autour de l'arête supérieure de la paroi frontale 22. L'extrémité du sachet se prolonge après la pliure de préférence de 5 à 30 mm. Un système d'attaches de type Velcro 23 permet de solidariser le volet 20 à la partie frontale 22, de manière à bien maintenir l'emballage fermé, surtout lorsqu'il est déjà entamé.According to Figure 1, the outer envelope 17 surrounds a bellows bag 18, in which is the packaged product. The side walls 19 of the envelope have no folding tabs. The flap 20 extends the back wall 21 of the outer envelope and folds and pinches the two faces 24 of the end of the bag 18 around the upper edge of the front wall 22. The end of the bag extends after the preferably folds from 5 to 30 mm. A Velcro type 23 fastening system makes it possible to secure the flap 20 to the front part 22, so as to keep the packaging closed, especially when it is already in use.

Dans une seconde forme d'exécution (Figures 2, 3) l'enveloppe extérieure 1 entoure un sachet 2 en laissant libres les côtés de celui-ci. Dans la forme d'exécution représentée au dessin, l'enveloppe est faite de deux feuilles collées ensemble au niveau du fond, de manière à pouvoir remplir par le fond avant collage. En variante, si le remplissage s'effectue par le haut, l'enveloppe 1 est faite d'une seule feuille.In a second embodiment (Figures 2, 3) the outer envelope 1 surrounds a bag 2 leaving the sides of it free. In the embodiment shown in the drawing, the envelope is made of two sheets glued together at the bottom, so that the bottom can be filled before gluing. Alternatively, if the filling is done from the top, the envelope 1 is made of a single sheet.

L'une des faces de l'enveloppe 1 comprend un volet 3 muni d'un prolongement 4 et un organe flexible 5 coopérant avec ce dernier pour maintenir le volet 3 ouvert ou fermé. L'extrémité supérieure du sachet 2 est collée à l'enveloppe 1 du côté du volet 3.One of the faces of the envelope 1 comprises a shutter 3 provided with an extension 4 and a flexible member 5 cooperating with the latter to keep the shutter 3 open or closed. The upper end of the bag 2 is glued to the envelope 1 on the side of the flap 3.

Dans la position représentée à la Figure 2, l'emballage est ouvert, et l'organe flexible 5 le maintient dans cette position. Pour fermer l'emballage, on rapproche le haut des faces de l'enveloppe 1 et on rabat le volet 3 au delà du point mort de l'organe flexible 5 comme représenté à la Figure 3, de sorte que le volet 3 est maintenu en position fermée. Les deux faces de l'extrémité du sachet 2 sont alors repliées et pincées par le volet 3, assurant une bonne fermeture de l'emballage.In the position shown in Figure 2, the package is open, and the flexible member 5 maintains it in this position. To close the packaging, the top of the faces of the envelope 1 are brought closer and the flap 3 is folded back beyond the neutral point of the flexible member 5 as shown in Figure 3, so that the flap 3 is kept in the closed position. The two faces of the end of the bag 2 are then folded and pinched by the flap 3, ensuring a good closure of the packaging.

Dans une troisième forme d'exécution (Figures 4 et 5) l'enveloppe extérieure entoure un sachet sur au moins quatre côtés, constituant une boite. Une partie de cette enveloppe est repliée en position de fermeture (Figure 4) selon les arêtes 6, 7, 8, 9, puis est collée à la paroi extérieure, formant un volume parallélépipédique A. Une autre partie de l'enveloppe est repliée selon les arêtes 10, 11, 12, 13, 14 et collée à la paroi extérieure, formant un volume parallélépipédique B et un volet 15. L'extrémité 16 du sachet intérieur est collée au volume A le long de l'arête 8 et au volume B le long de l'arête 13.In a third embodiment (Figures 4 and 5) the outer envelope surrounds a bag on at least four sides, constituting a box. A part of this envelope is folded back in the closed position (Figure 4) along the edges 6, 7, 8, 9, then is glued to the outer wall, forming a rectangular volume A. Another part of the envelope is folded according to the edges 10, 11, 12, 13, 14 and glued to the outer wall, forming a parallelepiped volume B and a flap 15. The end 16 of the inner bag is glued to the volume A along the edge 8 and to the volume B along edge 13.

En position fermée, les deux faces de cette extrémité sont pincées entre ces volumes.In the closed position, the two faces of this end are pinched between these volumes.

Le fonctionnement de l'ouverture est le suivant:
On soulève le volet 15 qui pivote autour de l'arête 10.The opening works as follows:
The flap 15 is raised, which pivots around the edge 10.

Le contour du volume B se comporte comme un parallélogramme déformable dont les pivots fixes sont les arêtes 10 et 14 et les pivots mobiles les arêtes 12 et 13. Cela signifie que la partie comprise entre les arêtes 12 et 13 pivote vers le haut et la gauche. En raison du collage le long de l'arête 13, la partie gauche de l'extrémité du sachet 16 suit ce mouvement, et en raison de sa constitution à soufflet, le sachet tend à s'ouvrir des deux côtés. La partie droite de l'extrémité du sachet 16 est entraînée vers le haut par sa partie gauche et en raison du collage le long de l'arête 8, la partie entre les arêtes 7 et 8 est d'abord tirée vers le haut. Comme avec le volume B, le contour du volume A constitue un parallélogramme déformable autour des pivots fixes 6 et 9 et la partie comprise entre les arêtes 7 et 8 pivote vers le haut et la droite. En écartant le volet 15 et le volume A, on obtient une ouverture totale représentée à la Figure 5, où les volumes A et B sont complètement aplatis.The contour of the volume B behaves like a deformable parallelogram whose fixed pivots are the edges 10 and 14 and the mobile pivots the edges 12 and 13. This means that the part between the edges 12 and 13 pivots up and to the left . Due to the bonding along the edge 13, the left part of the end of the bag 16 follows this movement, and due to its bellows constitution, the bag tends to open on both sides. The right part of the end of the bag 16 is driven upwards by its left part and due to the bonding along the edge 8, the part between the edges 7 and 8 is first pulled upwards. As with volume B, the outline of volume A constitutes a deformed parallelogram ble around the fixed pivots 6 and 9 and the part between the edges 7 and 8 pivots up and to the right. By removing the flap 15 and the volume A, a total opening is shown, shown in FIG. 5, where the volumes A and B are completely flattened.
