A closing unit (18) arranged at the end of the waist is closed after being filled with the articles. The packaging device made up of a folded cardboard blank is used to package the articles, where another closing unit (20) of the packaging device includes an inclined panel (26) arranged in a manner to form an angle less than 85 degrees with a given direction (10). An independent claim is also included for a device for packaging a bulk of articles.

Description

La présente invention se rapporte à un procédé de conditionnement d'articles en vrac ainsi qu'à un dispositif de conditionnement d'articles en vrac réalisé à partir de matériau semi rigide en feuille tel que le carton ou le carton ondulé.The present invention relates to a method of packaging bulk articles as well as to a bulk article packaging device made from semi-rigid sheet material such as cardboard or corrugated cardboard.

Le dispositif selon l'invention doit assurer le conditionnement des articles en vrac depuis le lieu du conditionnement jusqu'au consommateur final en passant par la ou le(s) plate(s)-forme(s) de stockage et le lieu de vente.The device according to the invention must ensure the packaging of the bulk items from the place of packaging to the final consumer via the platform (s) -form (s) storage (s) and the place of sale.

Les articles conditionnés et ainsi proposés à la vente, sont, à titre d'exemple, des fruits et légumes comme des pommes de terre, ou des objets divers comme des balles de jeu ou tout autre article qui nécessiterait d'être regroupé dans un conditionnement de transport et de vente.Articles packaged and thus offered for sale are, for example, fruits and vegetables such as potatoes, or various objects such as game balls or any other item that would need to be grouped in a package transportation and sales.

La présente invention se rapporte plus particulièrement aux procédés de conditionnement d'articles en vrac lors desquels les articles sont introduits dans un dispositif de conditionnement par gravité ou en flux poussé.The present invention relates more particularly to methods of packaging bulk articles in which the articles are introduced into a gravity or high-flow conditioning device.

Dans le cas du conditionnement de pommes de terre, pour une quantité de l'ordre de 2,5 Kg, les dispositifs de conditionnement utilisés sur le marché se présentent sous la forme d'une enveloppe souple tel qu'un sac, un sachet ou un filet, sur laquelle on rapporte éventuellement une bande réalisée à partir d'un matériau support souple qui sert à la fois de poignée et de surface de communication.In the case of potato packaging, for a quantity of the order of 2.5 kg, the packaging devices used on the market are in the form of a flexible envelope such as a bag, a bag or a net, on which there is optionally reported a strip made from a flexible support material which serves both as a handle and a communication surface.

Le procédé de conditionnement consiste alors à placer l'enveloppe sous un dispositif de remplissage, à déverser la quantité d'articles en vrac souhaitée et à fermer l'enveloppe.The packaging process then consists of placing the envelope under a filling device, pouring the desired quantity of bulk articles and closing the envelope.

Même si le procédé de conditionnement est relativement simple, ces dispositifs de conditionnement présentent des inconvénients majeurs.Although the packaging method is relatively simple, these packaging devices have major disadvantages.

Le premier inconvénient est de ne pas avoir une forme constante, des dimensions fixes et une structure rigide. Posés sur une palette, il est difficile de les empêcher d'en dépasser l'encombrement hors tout en largeur si ce n'est en les disposant dans un contenant rigide en bois, en carton, en métal ou autre qui nuit à leur visibilité sur le lieu de vente et qui renchérit les coûts de conditionnement et de transport.The first drawback is that it does not have a constant shape, fixed dimensions and a rigid structure. When placed on a pallet, it is difficult to prevent them from exceeding their overall width if not by placing them in a rigid wooden, cardboard, metal or other container that impairs their visibility on the pallet. the place of sale and which increases the cost of packaging and transport.

Le deuxième inconvénient est de ne pas valoriser l'article contenu, le sac, le sachet ou la poche étant synonyme de bas de gamme dans l'esprit du consommateur.The second disadvantage is not to value the article contained, the bag, the bag or the pocket being synonymous with low-end in the mind of the consumer.

Le troisième inconvénient est de ne pas disposer d'une surface de communication suffisante, réduite habituellement à la surface d'une étiquette ou d'une poignée et non à celle d'un conditionnement imprimé qui enveloppe le produit en totalité.The third disadvantage is that it does not have a sufficient communication area, usually reduced to the surface of a label or handle and not to that of a printed package that wraps the entire product.

Le quatrième inconvénient est d'assurer de manière insuffisante la protection des produits, tant pour la protection contre les chocs que pour la protection contre la lumière ce qui, par exemple, est essentiel pour des articles comme des pommes de terre ou des endives pour des raisons de sécurité sanitaire, de conservation, de préservation de l'aspect ...The fourth disadvantage is to insufficiently protect products, both for protection against shocks and for protection against light which, for example, is essential for items such as potatoes or chicory for reasons of safety, conservation, preservation of the appearance ...

Le cinquième inconvénient est de ne pas retenir les morceaux d'articles ainsi conditionnés susceptibles de se détacher ou la terre résiduelle qui les entoure et de souiller ainsi successivement les moyens de transport, les lieux de vente, les véhicules et mobiliers de rangement des consommateurs.The fifth disadvantage is not to retain the pieces of articles thus packaged may become detached or the residual earth that surrounds them and so contaminate the means of transport, sales places, vehicles and storage furniture of consumers successively.

Pour pallier à ces inconvénients, une solution consiste à utiliser des cagettes ou cageots à parois latérales et fond pleins comme dispositifs de conditionnement en bois, carton ou carton ondulé ou tout autre matériau.To overcome these drawbacks, one solution is to use crates or crates with side walls and solid bottom as packaging devices made of wood, cardboard or corrugated cardboard or any other material.

Cependant, cette solution conduit à augmenter sensiblement les coûts de conditionnement et ne permet pas d'obtenir un emballage fermé sécurisé en termes de vol et d'hygiène.However, this solution leads to significantly increase packaging costs and does not provide secure closed packaging in terms of theft and hygiene.

Selon un mode de conditionnement, lorsque le produit à conditionner est de type pulvérulent, il peut être conditionné dans un sachet qui est en suivant placé dans une boîte en carton avec pour inconvénient économique d'utiliser deux composants et de rendre la mécanisation plus complexe.According to a mode of packaging, when the product to be packaged is of the powder type, it can be packaged in a bag which is placed in a cardboard box with the economic disadvantage of using two components and making the mechanization more complex.

Dans le cas d'articles discrets, on peut également utiliser un conditionnement en carton de type étui ou autres principes de formes et volumes parallélépipédiques. Toutefois, l'utilisation de ces types de conditionnement en matière cartonnée est limitée à une certaine masse d'articles conditionnés rapidement limitée si on utilise des procédés de conditionnement lors desquels les articles sont introduits dans les dispositifs de conditionnement par gravité ou en flux poussé. Aussi, ce procédé de conditionnement n'est pas envisageable pour une masse de l'ordre de 2,5 Kg de pommes de terre par exemple, avec les emballages existants en matière cartonnée. En effet, lors du remplissage le contenu est libéré par gravité et brutalement dans le dispositif de conditionnement provoquant un gonflement ce qui nuit à la rigueur dimensionnelle, à la planéité du contour et à l'aspect structuré du dispositif de conditionnement.In the case of discrete articles, it is also possible to use a box-type carton packaging or other principles of parallelepipedal shapes and volumes. However, the use of these types of cardboard packaging is limited to a certain mass of packaged articles quickly limited if using packaging methods in which the articles are introduced into the gravity or high-flow conditioning devices. Also, this packaging process is not possible for a mass of the order of 2.5 Kg of potatoes for example, with existing packaging cardboard material. Indeed, during filling the content is released by gravity and brutally in the packaging device causing swelling which affects the dimensional rigor, the flatness of the contour and the structured appearance of the packaging device.

Dans le cas des emballages en matière cartonnée, une solution pour augmenter la masse d'articles conditionnés consiste à former l'emballage autour des produits. Cependant cette solution est préférentiellement retenue pour des produits qui peuvent être ordonnés telles que des boîtes de conserve par exemple. Par ailleurs, ce procédé de conditionnement visant à former l'emballage autour des articles nécessite des chaînes de conditionnement plus complexes, dont l'architecture est très différente des chaînes de conditionnement d'articles en vrac dans des enveloppes souples tels que des sacs, sachets ou des filets.In the case of cardboard packaging, a solution for increasing the weight of packaged articles consists in forming the packaging around the products. However, this solution is preferably used for products that can be ordered such as cans, for example. Furthermore, this packaging process for forming the packaging around the articles requires more complex packaging lines, whose architecture is very different from packaging chains of loose items in flexible envelopes such as bags, bags or nets.

Aussi, la présente invention vise à pallier aux inconvénients de l'art antérieur en proposant un procédé de conditionnement d'articles en vrac susceptible de s'adapter moyennant des modifications mineures aux chaînes de conditionnement mettant en oeuvre une enveloppe souple telle qu'un filet, et en utilisant un dispositif de conditionnement économique et recyclable n'ayant pas les inconvénients des dispositifs de conditionnement de type filets.Also, the present invention aims at overcoming the drawbacks of the prior art by proposing a method for packaging bulk articles that can be adapted by means of minor modifications to the packaging lines using a flexible envelope such as a net. , and using an economical and recyclable packaging device that does not have the disadvantages of net-type packaging devices.

A cet effet, l'invention a pour objet un procédé de conditionnement visant à introduire, selon une direction donnée, par gravité ou en flux poussé, des articles dans un dispositif de conditionnement, le dispositif de conditionnement étant réalisé à partir d'un flan plié en matière cartonnée et comprenant une ceinture avec à une première extrémité des premiers moyens d'obturation et à une seconde extrémité des seconds moyens d'obturation, l'ensemble délimitant une enceinte dans laquelle sont conditionnés les articles, le procédé de conditionnement consistant à introduire les articles via la première extrémité orientée vers l'arrivée des articles et à fermer les premiers moyens d'obturation après remplissage, caractérisé en ce qu'il consiste à utiliser un dispositif de conditionnement dont les seconds moyens d'obturation comprennent au moins un panneau incliné disposé de manière à former avec la direction donnée un angle a inférieur à 85°.For this purpose, the subject of the invention is a packaging method for introducing, in a given direction, by gravity or in a high flow, articles into a packaging device, the packaging device being made from a blank folded cardboard material and comprising a belt with at a first end of the first closure means and at a second end of the second closure means, the assembly defining an enclosure in which the articles are conditioned, the packaging method consisting of introducing the articles via the first end facing the arrival of the articles and closing the first filling means after filling, characterized in that it consists in using a conditioning device whose second closure means comprise at least one inclined panel arranged to form with the given direction an angle less than 85 °.

Le panneau incliné permet un écoulement progressif des articles et une régulation naturelle de leur flux comparé à un plan perpendiculaire à la direction de remplissage qui s'y opposerait brusquement. De plus, la partie inférieure rétrécie qui s'évase progressivement permet aux articles de se positionner progressivement en appui sur des parois à faible flexibilité au départ puis sur les articles déjà à l'intérieur quand les parois sont beaucoup moins rigides.The inclined panel allows a gradual flow of articles and a natural regulation of their flow compared to a plane perpendicular to the direction of filling that would oppose it abruptly. In addition, the narrowed lower part which gradually fades allows the items to position themselves gradually in support on walls with low flexibility initially then on the items already inside when the walls are much less rigid.

Ainsi, il est possible de conditionner, dans un dispositif de conditionnement réalisé à partir d'un flan plié en matière cartonnée en limitant ses déformations, une quantité d'articles en vrac supérieure au procédé de l'art antérieur utilisant un remplissage par gravité ou en flux.Thus, it is possible to condition, in a packaging device made from a folded cardboard blank by limiting its deformations, a quantity of bulk articles superior to the prior art method using gravity or flow filling.

Pour une plus grande clarté de la description de l'invention, nous prendrons l'exemple des produits agricoles tels que les fruits et légumes. Cependant, l'invention n'est pas limitée à cette application, le procédé de conditionnement pouvant convenir pour d'autres articles ou objets.For greater clarity of the description of the invention, we will take the example of agricultural products such as fruits and vegetables. However, the invention is not limited to this application, the packaging method may be suitable for other articles or objects.

Nous appliquerons le procédé au conditionnement de l'ordre de 2,5Kg de pommes de terre pour donner un ordre d'idée du volume à conditionner et des contraintes au moment du remplissage. Néanmoins, l'invention n'est pas limitée à ce type de produits et à cette quantité.We will apply the process to the ordering of 2.5 kg of potatoes to give an idea of the volume to be conditioned and constraints at the time of filling. Nevertheless, the invention is not limited to this type of products and this quantity.

Comme illustré sur la figure 5, l'invention se rapporte à un procédé de conditionnement visant à introduire, selon une direction donnée 10, par gravité ou en flux poussée, des articles 12 dans un dispositif de conditionnement 14.As illustrated on the figure 5 the invention relates to a packaging method for introducing, in a given direction 10, by gravity or in a high flow, articles 12 into a conditioning device 14.

Selon l'invention, le dispositif de conditionnement est réalisé à partir d'un flan plié en matière cartonnée et comprend une ceinture 16 comprenant à une première extrémité des premiers moyens 18 d'obturation et à une seconde extrémité des seconds moyens 20 d'obturation, l'ensemble délimitant une enceinte dans laquelle sont conditionnés les articles.According to the invention, the packaging device is made from a folded blank of cardboard material and comprises a belt 16 comprising at a first end of the first closure means 18 and at a second end of the second closure means 20 , the assembly delimiting an enclosure in which the articles are conditioned.

Comme illustré sur la figure 1, la ceinture 16 est constituée d'une succession de panneaux latéraux, selon un mode de réalisation au nombre de quatre, un premier panneau 16.1 constituant une première petite face latérale du conditionnement, un deuxième panneau 16.2 constituant une première grande face latérale du conditionnement, un troisième panneau 16.3 constituant une seconde petite face latérale du conditionnement et un quatrième panneau 16.4 constituant une seconde grande face latérale.As illustrated on the figure 1 , the belt 16 consists of a succession of side panels, according to a four embodiment, a first panel 16.1 constituting a first small side face of the package, a second panel 16.2 constituting a first large side face of the package, a third panel 16.3 constituting a second small side face of the package and a fourth panel 16.4 constituting a second large side face.

Afin de former une ceinture, le quatrième panneau 16.4 (ou respectivement le premier panneau 16.1) comprend au niveau du bord libre en regard du premier panneau 16.1 (ou respectivement du quatrième panneau 16.4) des moyens de jonction, notamment un petit panneau 22 formant une patte de jonction destinée à être encollée puis en contact avec la partie proche du bord libre du premier panneau 16.1 (ou respectivement du quatrième panneau 16.4) contre laquelle elle vient se superposer.In order to form a belt, the fourth panel 16.4 (or respectively the first panel 16.1) comprises at the free edge facing the first panel 16.1 (or respectively the fourth panel 16.4) means of junction, including a small panel 22 forming a connecting lug intended to be glued and then in contact with the near part of the free edge of the first panel 16.1 (or fourth panel respectively 16.4) against which it is superimposed.

Les panneaux latéraux successifs 16.1, 16.2, 16.3, 16.4 et la patte de jonction 22 sont reliés entre eux par des plis d'articulation 24.The successive lateral panels 16.1, 16.2, 16.3, 16.4 and the connecting tab 22 are interconnected by hinge folds 24.

De préférence, le dispositif de conditionnement comprend une ceinture 16 de section rectangulaire ou carrée, avec quatre panneaux latéraux, de manière à optimiser la constitution d'une charge sur une palette.Preferably, the packaging device comprises a belt 16 of rectangular or square section, with four side panels, so as to optimize the constitution of a load on a pallet.

Les premiers moyens 18 d'obturation comprennent au moins un panneau dont les formes sont adaptées à la section de la ceinture 16. Ces premiers moyens 18 d'obturation s'étendent dans un plan sensiblement perpendiculaire aux panneaux latéraux de la ceinture dans la configuration du dispositif de conditionnement fermé. Cette configuration permet d'obtenir un dispositif de conditionnement plus stable.The first closure means 18 comprise at least one panel whose shapes are adapted to the section of the belt 16. These first closure means 18 extend in a plane substantially perpendicular to the side panels of the belt in the configuration of the belt. closed packaging device. This configuration makes it possible to obtain a more stable conditioning device.

Selon un mode de réalisation, ces premiers moyens 18 d'obturation comprennent des volets 18.1, 18.2, 18.3, 18.4 dans le prolongement respectivement des panneaux latéraux 16.1, 16.2, 16.3 et 16.4, chaque volet étant relié au panneau latéral correspondant par un pli d'articulation 19.According to one embodiment, these first closure means 18 include flaps 18.1, 18.2, 18.3, 18.4 in the extension respectively of the side panels 16.1, 16.2, 16.3 and 16.4, each flap being connected to the corresponding side panel by a fold of articulation 19.

Selon l'invention, ces premiers moyens 18 d'obturation constituent le fond du dispositif de conditionnement dans la position d'utilisation par le consommateur final et assurent une bonne assise dans la mesure où ils sont perpendiculaires à la ceinture. Selon l'invention, le remplissage du dispositif de conditionnement est réalisé via ces premiers moyens 18 d'obturation qui sont maintenus ouverts et orientés vers l'arrivée des articles à conditionner pendant le remplissage et qui sont fermés seulement après le remplissage de manière à former le fond du dispositif de conditionnement par la suite.According to the invention, these first closure means 18 constitute the bottom of the packaging device in the position of use by the end consumer and provide a good base in so far as they are perpendicular to the belt. According to the invention, the filling of the packaging device is carried out via these first closure means 18 which are kept open and oriented towards the arrival of the articles to be packaged during filling and which are closed only after the filling so as to form the bottom of the packaging device thereafter.

Ces moyens d'obturation 18 sont maintenus en position fermés par tous moyens appropriés. Selon un mode de réalisation préféré, après remplissage, le volet 18.4 est rabattu, en suivant les volets 18.1 et 18.3 sont rabattus de manière à former un angle approximativement de 90°, puis le volet 18.2 est rabattu et collé sur les volets 18.1 et 18.3. Cet ordre de pliage est réalisé préférentiellement mais non exclusivement dans le but d'obtenir une meilleure étanchéité du dispositif de conditionnement. De préférence, le volet 18.2 a des dimensions sensiblement identiques à la section de la ceinture 16 afin d'assurer une meilleure étanchéité et une plus grande résistance du fond du dispositif de conditionnement.These sealing means 18 are held in closed position by any appropriate means. According to a preferred embodiment, after filling, the flap 18.4 is folded, following the flaps 18.1 and 18.3 are folded to form an angle of approximately 90 °, then the flap 18.2 is folded and glued to the flaps 18.1 and 18.3 . This folding order is preferably but not exclusively for the purpose of obtaining a better seal of the packaging device. Preferably, the flap 18.2 has dimensions substantially identical to the section of the belt 16 to ensure a better seal and greater strength of the bottom of the packaging device.

Selon l'invention, les seconds moyens 20 d'obturation comprennent au moins un panneau incliné 26 disposé de manière non perpendiculaire à la direction de chute des articles et formant avec ladite direction un angle a inférieur à 85°. Ainsi, le panneau incliné 26 forme un angle inférieur à 85° avec le panneau latéral 16.4. En complément, les panneaux latéraux 16.1 à 16.4 ont des dimensions et des formes adaptées en fonction de l'inclinaison du panneau 26. Ainsi, la présence d'un plan incliné et d'un rétrécissement de la partie inférieure du dispositif de conditionnement en position de remplissage permet d'obtenir un remplissage plus progressif et une moindre déformation du dispositif lors du conditionnement. En effet, lors du remplissage, comme illustré sur la figure 5, les articles sont introduits via la première extrémité de la ceinture, selon une direction sensiblement parallèle à la ceinture, tombent sur le plan incliné et roulent vers la partie inférieure étroite. Compte tenu de l'inclinaison relative entre le panneau incliné 26 et la direction de chute des articles, la résultante perpendiculaire au panneau incliné 26 des efforts exercés par un article sur le panneau incliné 26 est sensiblement inférieure à la résultante découlant de la chute du même article perpendiculairement au même fond. Par ailleurs, compte tenu du faible volume de la zone inférieure rétrécie, les articles présents dans cette zone exercent un effort à ce niveau susceptible d'être repris par des parois en matière cartonnée sans que ces dernières soient déformées.According to the invention, the second closure means 20 comprise at least one inclined panel 26 arranged non-perpendicularly to the falling direction of the articles and forming with said direction an angle α less than 85 °. Thus, the inclined panel 26 forms an angle less than 85 ° with the side panel 16.4. In addition, the side panels 16.1 to 16.4 have dimensions and shapes adapted according to the inclination of the panel 26. Thus, the presence of an inclined plane and a narrowing of the lower part of the conditioning device in position filling allows to obtain a more progressive filling and less deformation of the device during packaging. Indeed, when filling, as shown on the figure 5 , the articles are introduced via the first end of the belt, in a direction substantially parallel to the belt, fall on the inclined plane and roll towards the narrow lower part. Given the relative inclination between the inclined panel 26 and the falling direction of the articles, the resultant perpendicular to the inclined panel 26 of the forces exerted by an article on the inclined panel 26 is substantially less than the resultant resulting from the fall of the same article perpendicular to the same background. Moreover, given the small volume of the narrowed lower zone, the articles present in this zone exert an effort at this level likely to be taken up by cardboard walls without these being deformed.

Par conséquent, selon le procédé de l'invention, il est possible de conditionner une quantité d'articles en vrac supérieure au procédé de l'art antérieur utilisant un remplissage par gravité ou en flux poussé grâce à un remplissage plus progressif et une moindre déformation de la partie inférieure du dispositif lors du remplissage.Therefore, according to the method of the invention, it is possible to package a quantity of bulk articles greater than the prior art process using a gravity filling or in a deep flow due to a more progressive filling and less deformation of the lower part of the device during filling.

De plus, le procédé de conditionnement selon l'invention permet d'utiliser les chaînes de conditionnement sans modification majeure.In addition, the packaging method according to the invention allows the use of packaging lines without major modification.

Enfin, l'usage d'un flan en matière cartonnée permet de pallier aux inconvénients des dispositifs de conditionnement souples et ajourés tels que les filets.Finally, the use of a blank of cardboard material overcomes the disadvantages of flexible and openwork packaging devices such as nets.

De préférence, l'angle formé entre le panneau incliné 26 et l'un des panneaux de la ceinture permet d'obtenir des formes complémentaires lorsque deux dispositifs sont disposés tête-bêche, comme illustré sur les figures 8 et 9, afin d'optimiser la palettisation. Avantageusement, cet angle est de l'ordre de 45°.Preferably, the angle formed between the inclined panel 26 and one of the panels of the belt makes it possible to obtain complementary shapes when two devices are arranged head-to-tail, as illustrated in FIGS. Figures 8 and 9 , in order to optimize the palletization. Advantageously, this angle is of the order of 45 °.

Les bords du panneau incliné 26 sont reliés aux panneaux latéraux de la ceinture par tous moyens appropriés assurant une reprise des efforts et une étanchéité satisfaisantes entre ledit panneau incliné 26 et les panneaux latéraux.The edges of the inclined panel 26 are connected to the side panels of the belt by any appropriate means ensuring satisfactory efforts recovery and sealing between said inclined panel 26 and the side panels.

De préférence, le panneau incliné 26 est relié par un pli d'articulation 28 au panneau latéral 16.4.Preferably, the inclined panel 26 is connected by a hinge fold 28 to the side panel 16.4.

Comme illustré notamment sur les figures 1, 3-1, 4-1 et 7, selon un mode de réalisation, le panneau incliné 26 est relié à chaque paroi latérale 16.1 et 16.3 par un soufflet 30 constitué chacun de deux panneaux triangulaires 30' et 30". L'usage de soufflets 30 permet d'obtenir une meilleure étanchéité et une simplification des mouvements mécaniques, le fait d'appuyer latéralement sur les soufflets vers l'intérieur du dispositif provoquant le rapprochement du panneau incliné 26 et du panneau latéral 16.4.As illustrated in particular on figures 1 , 3-1 , 4-1 and 7 , according to one embodiment, the inclined panel 26 is connected to each side wall 16.1 and 16.3 by a bellows 30 each consisting of two triangular panels 30 'and 30 ".The use of bellows 30 provides a better seal and a simplification of the mechanical movements, the fact of pressing laterally on the bellows towards the interior of the device causing the approaching of the inclined panel 26 and the side panel 16.4.

Pour assurer la liaison entre le panneau incliné 26 et le panneau latéral 16.4, selon un mode de réalisation, le bord du panneau incliné 26 opposé au pli d'articulation 28 comprend un prolongement 32 susceptible d'être plaqué et collé contre un prolongement 34 prévu au niveau du bord du panneau latéral 16.4.To provide the connection between the inclined panel 26 and the side panel 16.4, according to one embodiment, the edge of the inclined panel 26 opposite the hinge fold 28 comprises an extension 32 which can be plated and glued against an extension 34 provided at the edge of the side panel 16.4.

Les prolongements 32 et 34 ont des formes sensiblement identiques, avec éventuellement des angles arrondis.The extensions 32 and 34 have substantially identical shapes, possibly with rounded corners.

Le collage est utilisé comme moyen préférentiel pour solidariser les parois, volets ou autres du conditionnement. Bien entendu ce type de liaison peut être remplacé par d'autres moyens aussi efficaces comme l'agrafage ou la mise en place de ruban adhésif par exemple.Bonding is used as a preferred means for securing the walls, shutters or other packaging. Of course this type of connection can be replaced by other equally effective means such as stapling or the introduction of adhesive tape for example.

Avantageusement, le dispositif de conditionnement comprend des moyens de préhension.Advantageously, the conditioning device comprises gripping means.

Ainsi, le dispositif de conditionnement peut comprendre une découpe 36 sur l'un des panneaux latéraux permettant le passage d'une partie de la main d'un utilisateur, notamment au niveau du panneau 16.4 afin de tenir le dispositif lors de son ouverture, de le pendre après re-fermeture ou encore de le suspendre à un crochet de présentation sur le lieu de vente ou de suspension dans la cuisine du consommateur.Thus, the packaging device may comprise a cutout 36 on one of the side panels allowing the passage of part of a user's hand, particularly at the level of the panel 16.4 in order to hold the device when it is opened, Hang it after re-closing or hang it on a presentation hook at the place of sale or suspension in the consumer's kitchen.

Avantageusement, les moyens de préhension comprennent des découpes 38 ménagées dans les prolongements 32 et 34 susceptibles de coopérer lorsque les deux prolongements sont plaqués et collés, l'ouverture ainsi obtenue permettant le passage d'une partie de la main d'un utilisateur comme illustré sur la figure 6. Cette configuration permet d'obtenir une meilleure reprise des efforts et simplifie la réalisation des moyens de préhension.Advantageously, the gripping means comprise cutouts 38 formed in the extensions 32 and 34 capable of cooperating when the two extensions are plated and glued, the opening thus obtained allowing the passage of part of the hand of a user as illustrated. on the figure 6 . This configuration makes it possible to obtain a better recovery of efforts and simplifies the realization of the gripping means.

Des lumières 40 peuvent être découpées afin de visualiser le contenu, de le ventiler ou d'assurer toute autre fonctionnalité d'échange entre le contenu et l'extérieur du dispositif de conditionnement. Selon un mode de réalisation, ces lumières 40 sont réparties sur le panneau incliné 26 et éventuellement disposées au niveau du pli 28 d'articulation.Lights 40 may be cut to view the content, to ventilate or to provide any other exchange functionality between the contents and the outside of the packaging device. According to one embodiment, these lights 40 are distributed on the inclined panel 26 and possibly arranged at the fold 28 of articulation.

Pour faciliter l'ouverture du dispositif de conditionnement, au moins une ligne de prédécoupe 42 peut être prévue. Avantageusement, une ligne de prédécoupe est prévue au niveau de la jonction du panneau incliné 26 et de son prolongement 32 afin de pouvoir les séparer et ouvrir le dispositif de conditionnement comme illustré sur la figure 7.To facilitate the opening of the packaging device, at least one precut line 42 may be provided. Advantageously, a precut line is provided at the junction of the inclined panel 26 and its extension 32 in order to be able to separate them and open the conditioning device as shown in FIG. figure 7 .

Le dispositif de conditionnement est réalisé à partir d'un flan découpé à plat puis plié et collé. Ce flan est en une matière cartonnée ou analogue. Dans le cas d'un matériau ayant une résistance plus élevée dans une direction que dans une autre comme le carton ou le carton ondulé, le choix de la direction parallèle aux cannelures ou au « sens fibre » du matériau sera préférentiellement dans la direction perpendiculaire aux plis d'articulation des panneaux 18 pour améliorer la résistance à la compression du dispositif lorsqu'il sera palettisé comme indiqué ultérieurement.The packaging device is made from a blank cut flat and folded and glued. This blank is a cardboard material or the like. In the case of a material having a higher resistance in one direction than in another such as cardboard or corrugated board, the choice of the direction parallel to the splines or the "fiber direction" of the material will preferably be in the direction perpendicular to the hinge folds of the panels 18 to improve the compressive strength of the device when it is palletized as indicated later.

Avant d'être placés dans un magasin de stockage, les flans sont découpés et disposés à plat. Avantageusement, les panneaux 16.1 et 16.4 sont reliés de manière à former la ceinture 16, les grandes faces latérales 16.2 et 16.4 étant partiellement plaquées l'une contre l'autre, comme illustré sur la figure 2. Cette configuration à plat permet de faciliter le transport et stockage des flans depuis le lieu de fabrication jusqu'au lieu de conditionnement.Before being placed in a storage magazine, the blanks are cut and laid flat. Advantageously, the panels 16.1 and 16.4 are connected so as to form the belt 16, the large side faces 16.2 and 16.4 being partially pressed against each other, as shown in FIG. figure 2 . This flat configuration facilitates the transport and storage of blanks from the place of manufacture to the place of packaging.

Le procédé de conditionnement est maintenant décrit au regard des figures 3-1 à 3-6 et 4-1 à 4-6.The packaging process is now described with regard to Figures 3-1 to 3-6 and 4-1 to 4-6 .

Comme illustré sur la figure 3-1, la première étape consiste à mettre le dispositif de conditionnement en volume de manière à ce que la ceinture ait une section sensiblement rectangulaire. De préférence, la première extrémité de la ceinture est orientée vers le haut. Lors de cette étape, les grandes faces latérales sont écartées.As illustrated on the figure 3-1 , the first step is to put the volume conditioning device so that the belt has a substantially rectangular section. Preferably, the first end of the belt is oriented upwards. During this step, the large side faces are spaced apart.

Comme illustré sur les figures 3-2 et 4-2, la seconde étape consiste à fermer la seconde extrémité en déformant vers l'intérieur les soufflets 30 afin d'obtenir une partie inférieure rétrécie et un panneau incliné 26 lorsque les parties triangulaires de chaque soufflet sont plaquées l'une contre l'autre. Les prolongements 32 et 34 sont plaqués et collés l'un contre l'autre.As illustrated on Figures 3-2 and 4-2 the second step is to close the second end by deforming the bellows 30 inwardly to obtain a narrowed lower portion and an inclined panel 26 when the triangular portions of each bellows are pressed against each other. The extensions 32 and 34 are plated and glued together.

La troisième étape consiste à remplir le dispositif de conditionnement comme illustré sur la figure 3-3, les articles étant introduits par gravité ou flux poussé via la première extrémité orientée vers le haut et positionnée sous une arrivée d'articles à conditionner. Le panneau incliné 26 permet un écoulement progressif des articles et une régulation naturelle de leur flux comparé à un plan perpendiculaire à la direction de remplissage qui s'y opposerait brusquement. De plus, la partie inférieure rétrécie qui s'évase progressivement permet aux articles de se positionner progressivement en appui sur des parois à faible flexibilité au départ puis sur les articles déjà à l'intérieur quand les parois sont beaucoup moins rigides.The third step is to fill the packaging device as illustrated on the figure 3-3 , the articles being introduced by gravity or pushed flow via the first end upwards and positioned under an arrival of articles to be packaged. The inclined panel 26 allows a gradual flow of articles and a natural regulation of their flow compared to a plane perpendicular to the direction of filling which would oppose it sharply. In addition, the narrowed lower part which gradually fades allows the items to position themselves gradually in support on walls with low flexibility initially then on the items already inside when the walls are much less rigid.

La quatrième étape consiste à fermer la première extrémité en rabattant le volet 18.4 comme illustré sur les figures 3-4 et 4-4, puis les volets 18.1 et 18.3 comme illustré sur les figures 3-5 et 4-5, et enfin le volet 18.2.The fourth step is to close the first end by folding the flap 18.4 as illustrated on the Figures 3-4 and 4-4 , then the shutters 18.1 and 18.3 as illustrated on the Figures 3-5 and 4-5 , and finally part 18.2.

On obtient alors un dispositif de conditionnement rempli et fermé comme illustré sur les figures 3-6 et 4-6.We then obtain a filled and closed packaging device as illustrated on the Figures 3-6 and 4-6 .

Le procédé de conditionnement peut comprendre une étape de palettisation.The packaging method may comprise a palletizing step.

Les dispositifs de conditionnement sont agencés par paires, chaque paire comprenant deux dispositifs appariés tête bêche comme illustré sur la figure 8. Chaque paire est sensiblement parallélépipédique grâce aux formes complémentaires des panneaux inclinés.The conditioning devices are arranged in pairs, each pair comprising two paired devices head-to-tail as shown in FIG. figure 8 . Each pair is substantially parallelepipedal thanks to the complementary shapes of the inclined panels.

Les paires de dispositifs sont disposées de manière à former des couches qui sont empilées les unes sur les autres de manière à obtenir une charge palettisée telle qu'illustrée sur la figure 9.The pairs of devices are arranged to form layers that are stacked on top of one another to provide a palletized load as illustrated in FIG. figure 9 .

Cet agencement permet d'optimiser la palettisation.This arrangement optimizes palletizing.

Selon un autre avantage du dispositif de conditionnement selon l'invention, il permet une palettisation mécanique et l'obtention d'une charge palettisée homogène et stable sans utilisation d'emballages de conformation et de regroupement.According to another advantage of the packaging device according to the invention, it allows mechanical palletizing and obtaining a homogeneous and stable palletized load without the use of conformation packaging and grouping.

La direction la plus résistance du matériau utilisé pour réaliser les dispositifs étant orientée selon la hauteur de la palette, la capacité de résistance au gerbage du dispositif est ainsi améliorée.Since the most resistant direction of the material used to produce the devices is oriented according to the height of the pallet, the stacking resistance capacity of the device is thus improved.

On note que les dispositifs étant disposés tête bêche, le panneau incliné de l'un est plaqué contre le panneau incliné de l'autre.Note that the devices being arranged head to tail, the inclined panel of one is pressed against the inclined panel of the other.

Cette disposition des lumières 40, qui ont pour but de permettre au consommateur de voir les articles qu'il achète et éventuellement de les toucher, présente l'avantage d'assurer une meilleure conservation de certains articles qui seront ainsi à l'abri de la lumière à l'exception d'une partie de la dernière couche supérieure.This provision lights 40, which are intended to allow the consumer to see the items he buys and possibly to touch them, has the advantage of ensuring better preservation of certain items that will be safe from the light except for part of the last top layer.

En combinaison avec l'une 44 de ces lumières 40, une des épaisseurs du dispositif de poignée 38 vient, après ouverture, permettre la re-fermeture de l'emballage après avoir déchiré la bande d'arrachage 42 et après chaque prélèvement de contenu. Pour permettre cette re-fermeture, selon un mode de réalisation préférentiel, un double pli est utilisé pour réaliser la ligne de pliage 46 entre le panneau 16-4 de la ceinture et le prolongement 34.
