Abstract

The packing method of the present invention uses a pocket (1) consisting of a flexible sheet folded and fixed over its periphery provided with an open neck (2); it is characterised in that the said pocket (1) is pre-formed to give a parallelepipedal form while ensuring it has a certain consistency, depending on the said volume, then the pre-formed pocket is filled and the neck is sealed. The pre-forming is then ensured with the aid of a forming die which ensures the positioning of stiffening elements (3 and 7) onto the periphery of the pocket (1). The invention will be especially applicable for the packing of solid bulk materials or liquid materials. <IMAGE>

Description

L'invention est relative à un procédé de conditionnement parallélépipédique et le conditionnement ainsi obtenu. L'invention trouvera tout particulièrement son application pour l'emballage de matières liquides ou solides en vrac en grande quantité, par exemple, de l'ordre de 1.000 à 5.000 litres.The invention relates to a parallelepipedic packaging process and the packaging thus obtained. The invention will particularly find its application for the packaging of liquid or solid materials in bulk in large quantities, for example, of the order of 1,000 to 5,000 liters.

Les emballages vides qui doivent être acheminés depuis leur lieu de fabrication jusqu'à leur lieu de remplissage doivent de préférence occuper un faible volume afin de minimiser le coût du transport.Empty packages which must be transported from their place of manufacture to their place of filling should preferably occupy a small volume in order to minimize the cost of transport.

Par contre, une fois remplis, il est préférable qu'ils prennent une forme facilement stockable, telle qu'une forme parallélépipédique qui peut être gerbée.On the other hand, once filled, it is preferable that they take an easily storable form, such as a parallelepiped shape which can be stacked.

Malheureusement, ces exigences sont contraires et actuellement il est nécessaire de faire un choix entre un emballage rigide qui occupe un grand volume même à vide mais qui, toutefois, remplitpeut être empilé, ou un emballage souple tel que les poches qui prennent une forme de berlingot une fois remplies et donc se prêtent difficilement pour être stockées sur un minimum de place.Unfortunately, these requirements are contrary and currently it is necessary to make a choice between a rigid packaging which occupies a large volume even when empty but which, however, fills can be stacked, or a flexible packaging such as the pockets which take a form of cartons once filled and therefore difficult to lend themselves to being stored on a minimum of space.

Pour tenter de pallier à ces inconvénients, il a été développé des poches pré-formées qui se développent selon des formes géométriques qui se rapprochent du parallélépipède, cependant, à vide, leur repliage particulier fait qu'elles occupent un volume relativement important.In an attempt to overcome these drawbacks, pre-formed pockets have been developed which develop in geometric shapes which approach the parallelepiped, however, when empty, their particular folding means that they occupy a relatively large volume.

Aussi, il n'existe pas de solution réellement satisfaisante et les problèmes rencontrés notamment pour le transport de matières premières d'origine tropicale alors que la fabrication des emballages est située en Europe sont particulièrement délicats à résoudre.Also, there is no really satisfactory solution and the problems encountered in particular for the transport of raw materials of tropical origin while the packaging is located in Europe are particularly difficult to solve.

Le but principal de la présente invention est un procédé de conditionnement parallélépipédique de matériaux solides en vrac ou de liquides qui donc présente tous les avantages des emballages rigides, c'est-à-dire leur facilité de stockage en étant gerbables et en pouvant être disposés côte à côte sans perte de place, en partant d'une poche constituée d'une feuille souple, c'est-à-dire un matériau de base peu onéreux et surtout qui peut être facilement plié et occuper un volume minimum à vide.The main object of the present invention is a method of parallelepipedic packaging of bulk solid materials or liquids which therefore has all the advantages of rigid packaging, that is to say their ease of storage by being stackable and being able to be arranged. side by side without losing space, starting from a pocket made of a flexible sheet, that is to say an inexpensive base material and above all which can be easily folded and occupy a minimum volume when empty.

Par conséquent, le procédé de conditionnement de la présente invention permet de cumuler les avantages des emballages rigides et les avantages des emballages souples pour leur transport à vide.Consequently, the packaging method of the present invention makes it possible to combine the advantages of rigid packaging and the advantages of flexible packaging for their empty transport.

De plus, le procédé de conditionnement de la présente invention est réversible et par conséquent, les emballages peuvent être récupérés et réexpédiés après utilisation.In addition, the packaging process of the present invention tion is reversible and therefore, the packaging can be collected and returned after use.

Un autre but de la présente invention est de présenter un conditionnement qui n'utilise que des matériaux standards et facilement disponibles. Le coût unitaire d'un emballage de la présente invention est donc très bas.Another object of the present invention is to present a packaging which uses only standard and readily available materials. The unit cost of a package of the present invention is therefore very low.

Selon un mode de réalisation du procédé de la présente invention, celui-ci permet d'obtenir le conditionnement sous vide d'un matériau en particulier d'un liquide oxydable tel que du vin.According to an embodiment of the process of the present invention, this makes it possible to obtain the vacuum packaging of a material in particular of an oxidizable liquid such as wine.

Il s'agit d'une caractéristique particulièrement appréciable car l'absence d'air allonge considérablement la durée de conservation du contenu.This is a particularly appreciable characteristic because the absence of air considerably prolongs the shelf life of the contents.

En outre, l'utilisation d'un insert pour le remplissage et l'évacuation du liquide conditionné sous vide autorise un réemploi de la poche.In addition, the use of an insert for filling and evacuating the vacuum-packed liquid allows reuse of the bag.

D'autres buts et avantages de la présente invention apparaîtront au cours de la description qui va suivre qui n'est cependant donnée qu'à titre indicatif et qui n'a pas pour but de la limiter.Other objects and advantages of the present invention will appear during the description which follows which is however given only for information and which is not intended to limit it.

Le procédé de conditionnement parallélépipédique notamment de matériaux solides en vrac ou de liquides dans une poche constituée d'une feuille souple repliée ou de deux feuilles superposées et fixées sur leur périphérie, est caractérisé en ce que :

  • - on rigidifie une ou plusieurs parties de la poche souple aux formes d'au moins une des faces du volume parallélépipédique développé à obtenir après remplissage, à l'aide d'un ou plusieurs panneaux de conformation rapportés. ""
  • - on remplit la poche en contrôlant son développement à l'aide de parois rigides externes aux dimensions du volume du conditionnement final à réaliser.
The parallelepipedic packaging process, in particular for solid bulk materials or liquids in a bag made up of a folded flexible sheet or of two superimposed sheets fixed on their periphery, is characterized in that:
  • - One or more parts of the flexible pouch are stiffened to the shapes of at least one of the faces of the developed parallelepiped volume to be obtained after filling, using one or more added shaping panels. ""
  • - the bag is filled by controlling its development using rigid walls external to the dimensions of the volume of the final packaging to be produced.

Le conditionnement selon le procédé de la présente invention est caractérisé par le fait que la feuille souple utilisée pour la confection de la poche présente sur sa surface des pièces rapportées de forme triangulaire fixées sur la dite feuille selon une liaison en forme de T.The packaging according to the method of the present invention is characterized by the fact that the flexible sheet used for making the pocket has on its surface triangular shaped attachments fixed on said sheet according to a T-shaped connection.

Le procédé de conditionnement de la présente invention est destiré à l'emballage de matériaux solides en vrac ou de liquides. La base de l'emballage est une poche constituée d'une feuille souple repliée ou de deux feuilles superposées et fixées sur leur périphérie munie d'un ou plusieurs cols ouverts.The packaging method of the present invention is intended for packaging solid bulk materials or liquids. The base of the packaging is a pocket consisting of a folded flexible sheet or of two superimposed sheets fixed on their periphery provided with one or more open collars.

La figure 1 représente une telle poche 1 munie d'un col ouvert 2 réalisé dans une feuille de matériau souple tel qu'un PVC.FIG. 1 represents such a pocket 1 provided with an open neck 2 produced in a sheet of flexible material such as PVC.

Selon le procédé de la présente invention, on pré-forme la poche 1 selon un volume parallélépipédique en lui assurant une certaine consistance selon la dite forme puis, on remplit la poche pré-formée et on scelle le col. Il est important qu'à l'issue du remplissage, la poche pré-formée conserve la forme parallélépipédique qui lui a été donnée. En effet, de la sorte, le conditionnement se prêtera très facilement aux transport et stockage des matériaux tout en occupant un volume minimum et une surface au sol réduite puisque les conditionnements sont empilables.According to the method of the present invention, the pocket 1 is pre-formed according to a parallelepiped volume while ensuring a certain consistency according to said shape then, the pre-formed pocket is filled and the neck is sealed. It is important that after filling, the pre-formed pocket retains the rectangular shape that has been given to it. Indeed, in this way, the packaging will lend itself very easily to the transport and storage of materials while occupying a minimum volume and a reduced floor area since the packaging is stackable.

Les figures la à d illustrent les différentes phases du pré-formage de la poche 1.Figures la to d illustrate the different phases of the preforming of the bag 1.

Le pré-formage a lieu dans un conformateur qui est un appareil muni de moyens de poussée et qui permet la mise en place d'éléùents de conformation qui assurent à la poche une certaine consistance ou rigidité selon une forme prédéterminée, ici, il s'agit d'un volume parallélépipédique.The pre-forming takes place in a shaping device which is a device provided with pushing means and which allows the establishment of shaping elements which provide the bag with a certain consistency or rigidity according to a predetermined shape, here it is acts of a parallelepiped volume.

La figure la représente la première phase du procédé durant laquelle on rigidifie les deux faces de la poche 1 selon une forme rectangulaire à l'aide d'éléments de conformation 3. Ces éléments de conformation 3 rigides ou semi-rigides sont fixés sur la poche 1 à l'aide de moyens de liaison 4 amovibles.FIG. 1a represents the first phase of the process during which the two faces of the pocket 1 are stiffened in a rectangular shape using shaping elements 3. These rigid or semi-rigid shaping elements 3 are fixed to the pocket 1 using removable connection means 4.

On insuffle de l'air comprimé dans la poche par le col 2 pour la développer, par exemple, en ayant introduit préalablement un tuyau d'air comprimé 5 par l'ouverture du col 2.Compressed air is blown into the pocket through the neck 2 to develop it, for example, having previously introduced a compressed air pipe 5 through the opening of the neck 2.

La figure lb illustre la deuxième phase du procédé. La poche 1 étant disposée dans le conformateur, les moyens de poussée 6 de ce dernier permettent d'appliquer contre la poche 1 des éléments de conformation latéraux 7. L'application de ces éléments de conformation 7 est également effectuée à l'aide de moyens de poussée non illustrés à lafigu- re lb mais qui se présentent sous la forme de vérins ou autre. Les éléments de conformation latéraux 7, de forme rectangulaire, sont fixés sur la poche 1 à l'aide de moyens de liaison 4 qui assurent leur maintien en place.Figure 1b illustrates the second phase of the process. The pocket 1 being disposed in the shaping device, the pushing means 6 of the latter make it possible to apply against the pocket 1 lateral shaping elements 7. The application of these shaping elements 7 is also carried out using means thrust not illustrated in fig. 1b but which are in the form of jacks or the like. The lateral shaping elements 7, of rectangular shape, are fixed to the pocket 1 by means of connecting means 4 which keep them in place.

Les élements de conformation de forme rectangulaire ayant été disposés sur le pourtour de la poche 1, cette dernière prend une allure générale de parallélépipède telle qu'illustrée à la figure lc, seuls des goussets 8 disposés aux quatre coins de la poche dépassent du cadre parallélépipédique, ainsi éventuellement que le ou les cols 2.The shaping elements of rectangular shape having been arranged on the periphery of the pocket 1, the latter takes on the general appearance of a parallelepiped as illustrated in FIG. 1c, only gussets 8 arranged at the four corners of the pocket protrude from the parallelepiped frame , as well as the collar (s) 2.

Puisque les éléments de conformation rectangulaires 3 et 7 sont fixés sur la poche 1, il est possible de rétracter les moyens de poussée 6 du conformateur tout en conservant une forme parallélépipédique pour la poche 1.Since the rectangular shaping elements 3 and 7 are fixed on the pocket 1, it is possible to retract the pushing means 6 of the shaper while retaining a parallelepiped shape for the pocket 1.

Enfin, on replie les goussets 8 à plat le long des faces latérales 7 de la poche où ils seront immobilisés.Finally, the gussets 8 are folded flat along the side faces 7 of the pocket where they will be immobilized.

Il est à noter que les goussets 8 peuvent être coupés et scellés lors de la phase illustrée à la figure lc, ce qui évite de devoir les rabattre et les immobiliser le long des faces latérales 7.It should be noted that the gussets 8 can be cut and sealed during the phase illustrated in FIG. 1c, which avoids having to fold them down and immobilize them along the lateral faces 7.

A l'issue de ces étapes, la poche prend donc une allure parallélépipédique et est rigidifiée à l'aide des éléments de conformation 7 et 3.At the end of these steps, the pocket therefore takes on a parallelepiped shape and is stiffened using the shaping elements 7 and 3.

Il faut alors distinguer la nature de la matière à conditionner.We must then distinguish the nature of the material to be conditioned.

En premier lieu, s'il s'agit d'un liquide, il suffit alors de remplir la poche 1 et de sceller le col 2, le tout pouvant être stocké ou transporté sous une forme parallélépipédique imposée par les éléments de conformation.Firstly, if it is a liquid, it then suffices to fill the bag 1 and seal the neck 2, the whole being able to be stored or transported in a rectangular shape imposed by the shaping elements.

On peut remarquer que le transport du conditionnement vide occupe un très faible volume puisque le conditionnement peut se résumer en une poche 1 réalisée à partir d'une feuille souple repliée ou de deux feuilles souples et de quatre éléments de conformation qui se présentent par exemple sous la forme de plaques. Les conditionnements vides peuvent être empilés sans perte de place.It can be noted that the transport of the empty packaging occupies a very small volume since the packaging can be summed up in a bag 1 made from a folded flexible sheet or from two flexible sheets and from four shaping elements which are for example under the shape of plates. Empty packages can be stacked without wasting space.

Par contre, s'il s'agit de conditionner des matériaux solides en vrac, alors le procédé de conditionnement de la présente invention suivra les étapes illustrées aux figures 2 qui sont préférentielles. Il s'agit d'un conditionnement du matériau sous vide qui présente deux avantages, d'une part des meilleures conditions pour la conservation du produit s'il s'agit de denrées périssables grâce au vide et d'autre part la mise sous vide permet le maintien en place et donc la conservation de la forme du conditionnement.On the other hand, if it is a question of packaging solid materials in bulk, then the packaging method of the present invention will follow the steps illustrated in FIGS. 2 which are preferred. This is a vacuum packaging of the material which has two advantages, on the one hand the best conditions for the conservation of the product if it is perishable foodstuffs thanks to the vacuum and on the other hand the vacuum allows the holding in place and therefore the conservation of the shape of the packaging.

Tout d'abord, il est judicieux de disposer autour de la poche 1 pré-formée selon le procédé décrit précédemment, une sangle 9 qui facilitera la manutention au moyen d'éléments de levage.First of all, it makes sense to arrange around the po che 1 pre-formed according to the method described above, a strap 9 which will facilitate handling by means of lifting elements.

La poche pré-formée 1 entourée de la sangle 9 est placée dans une cuve 10 dont les dimensions sont sensiblement identiques à celles de la poche pré-formée 1 telle qu'illustrée à la figure 2a.The pre-formed pocket 1 surrounded by the strap 9 is placed in a tank 10 whose dimensions are substantially identical to those of the pre-formed pocket 1 as illustrated in FIG. 2a.

Cet ensemble est mis en place sur le lieu de remplissage tel qu'illustré à la figure 2b. La buse 11 de remplissage du produit et de vidange de l'air est mise en place dans le col 2 de la poche 1. L'étanchéité au niveau de la buse Il et du col 2 est assurée à l'aide d'un joint gonflant 12. Le remplissage du produit 13 est assuré alors qu'éventuellement la cuve 10 est disposée sur une table vibrante 14 qui aIé- liore la répartition du remplissage de produit 13.This assembly is put in place at the filling location as illustrated in Figure 2b. The nozzle 11 for filling the product and for draining the air is placed in the neck 2 of the pocket 1. The seal at the nozzle II and the neck 2 is ensured by means of a seal. swelling 12. The product 13 is filled while possibly the tank 10 is placed on a vibrating table 14 which improves the distribution of the product filling 13.

Ensuite, un couvercle 15 est mis en place sur la cuve 10 de façon à enfermer la poche remplie 1.Then, a cover 15 is placed on the tank 10 so as to enclose the filled pocket 1.

Le couvercle 15 est adapté sur la cuve 10 de façon étanche ce qui permet de créer le vide dans la cuve 10 à l'aide d'une pompe à vide auxiliaire qui est réunie à la cuve 10 par l'intermédiaire d'une gaine 16.The cover 15 is fitted on the tank 10 in a leaktight manner which makes it possible to create the vacuum in the tank 10 using an auxiliary vacuum pump which is joined to the tank 10 by means of a sheath 16 .

Puis, on scelle le col 2 de la poche 1 à l'aide de mâchoires hydrauliques 17. Dans le cas d'une poche réalisée en PVC, les mâchoires 17 pourront avantageusement réaliser une soudure du col 2.Then, the neck 2 of the pocket 1 is sealed using hydraulic jaws 17. In the case of a pocket made of PVC, the jaws 17 can advantageously weld the neck 2.

Puis, on repressurise la cuve 1 à la pression extérieure, et on retire le couvercle 15. La poche 1 peut alors être déchargée de la cuve 10 à l'aide d'un appareil de levage 18 qui prendra appui sur la sangle 9.Then, the tank 1 is repressurized at external pressure, and the cover 15 is removed. The bag 1 can then be discharged from the tank 10 using a lifting device 18 which will bear on the strap 9.

La cuve 10 sera avantageusement pourvue d'empreintes à sa partie inférieure qui faciliteront la prise en charge de la cuve 10 par un chariot de levage à fourche de type standard. De la sorte, les différentes opérations nécessaires pour le remplissage de la poche 1 pourront être effectuées successivement sur différents postes distincts.The tank 10 will advantageously be provided with indentations at its lower part which will facilitate the handling of the tank 10 by a standard type forklift truck. In this way, the various operations necessary for filling the pocket 1 can be carried out successively on different separate stations.

A l'issue du déchargement de la poche 1 de la cuve 10 telle qu'illustrée à la figure 2d, les éléments de conformation 3 et 7 qui sont toujours présents dans la poche 1 peuvent enfin être retirés. En effet, en raison de la mise sous vide et donc du vide qui règne à l'intérieur de la poche, celle-ci conserve sa forme parallélépipédique même après avoir retiré les éléments de conformation.At the end of the unloading of the bag 1 from the tank 10 as illustrated in FIG. 2d, the shaping elements 3 and 7 which are still present in the bag 1 can finally be removed. Indeed, due to the vacuum and therefore the vacuum that prevails inside the bag, it retains its parallelepiped shape even after removing the shaping elements.

Il s'agit d'un conditionnement extrêmement bon marché puisqu'il est réalisé à partir d'une feuille souple qui peut être d'épaisseur très modeste. Par ailleurs, la forme parallélépipédique du conditionnement est extrêmement rigide grâce au vide intérieur réalisé.It is an extremely inexpensive packaging since it is produced from a flexible sheet which may be thick. very modest sister. Furthermore, the parallelepiped shape of the packaging is extremely rigid thanks to the internal vacuum created.

Encore une fois, les goussets 8 peuvent être coupés et scellés après l'opération de remplissage, ou tout simplement fixés sur les côtés latéraux du conditionnement parallélépipédique.Again, the gussets 8 can be cut and sealed after the filling operation, or simply attached to the lateral sides of the parallelepiped packaging.

Différentes solutions pour la fixation amovible des éléments de conformation 3 et 7 peuvent être adoptées, toutefois, un mode préférentiel est décrit ci-après.Different solutions for the removable fixing of the shaping elements 3 and 7 can be adopted, however, a preferred method is described below.

La figure 3 illustre la poche du conditionnement de la présente invention réalisée à partir du repliage d'une gaine ou feuille 19 sur elle-même. La dite feuille souple 19 est pourvue, sur sa surface, de moyens de liaison 4 qui permettent la mise en place de façon amovible d'éléments de conformation non illustrés.Figure 3 illustrates the packaging bag of the present invention made from the folding of a sheath or sheet 19 on itself. Said flexible sheet 19 is provided, on its surface, with connecting means 4 which make it possible to removably put in place non-illustrated shaping elements.

Ces moyens de liaison 4 se présentent sous la forme de pièces 20, illustrées à la figure 4, de forme triangulaire et fixées sur la dite feuille 19 selon une liaison en forme de T 21.These connecting means 4 are in the form of parts 20, illustrated in FIG. 4, of triangular shape and fixed on said sheet 19 according to a T-shaped connection 21.

Cette liaison en forme de T permet de créer deux petites poches dans le triangle où pourront être introduits les coins des éléments de conformation de forme rectangulaire.This T-shaped connection makes it possible to create two small pockets in the triangle into which the corners of the shaping elements of rectangular shape can be introduced.

La figure 5 illustre la poche 1 obtenue par soudure 22 de la périphérie de la gaine ou feuille 19 pourvue toutefois d'un ou plusieurs cols 2 ouverts.FIG. 5 illustrates the pocket 1 obtained by welding 22 from the periphery of the sheath or sheet 19, however provided with one or more open necks 2.

Aux figures 1, les éléments de conformation représentés ont la forme de plaques rectangulaires, chaque plaque latérale 7 étant munie de fentes par lesquelles sont introduits les goussets 8 afin d'être immobilisés le long des parois latérales de la poche 1.In FIGS. 1, the shaping elements shown have the form of rectangular plates, each side plate 7 being provided with slots through which the gussets 8 are introduced so as to be immobilized along the side walls of the pocket 1.

Toutefois, les éléments de conformation peuvent se présenter sous une forme de ressort en croix 23 tel qu'illustré à la figure 6.However, the shaping elements can be in the form of a cross spring 23 as illustrated in FIG. 6.

En outre, ce ressort en forme de croix 23 sera avantageusement muni de bandes textiles ou caoutchouc pour conserver la flexibilité du cadre, transversales 24 au-dessous desquelles sont rabattus les goussets 8.Furthermore, this cross-shaped spring 23 will advantageously be provided with textile or rubber bands to preserve the flexibility of the transverse frame 24 below which the gussets 8 are folded down.

Les extrémités des branches du ressort en croix 23 sont disposées dans les poches réalisées dans les pièces rapportées triangulaires 20.The ends of the branches of the cross spring 23 are placed in the pockets made in the triangular inserts 20.

Les figures 7 à 13 illustrent un conditionnement réalisé selon le procédé défini précédemment et qui est tout particulièrement destiné au transport des liquides.Figures 7 to 13 illustrate a packaging produced according to the method defined above and which is particularly intended for the transport of liquids.

La figure 7 illustre une poche 1 particulièrement adaptée pour recevoir des liquides qui présente un ou plusieurs cols de remplissage 2 et qui est munie d'éléments de conformation 3 et 7 sur sa périphérie de façon à assurer à la poche 1 une forme parallélépipédique. La mise en place des éléments de conformation 3 et 7 est identique à celle envisagée précédemment. Toutefois, les éléments de conformation 7 qui se présentent sous forme de plaques seront avantageusement renforcés par des traverses latérales 25. Ces tranverses 25 sont rapportées sur les plaques 7 et 3 et présenteront une bonne rigidité.FIG. 7 illustrates a pocket 1 particularly suitable for receiving liquids which has one or more filling necks 2 and which is provided with shaping elements 3 and 7 on its periphery so as to provide the pocket 1 with a parallelepiped shape. The positioning of the shaping elements 3 and 7 is identical to that previously envisaged. However, the shaping elements 7 which are in the form of plates will advantageously be reinforced by lateral crosspieces 25. These crosspieces 25 are attached to the plates 7 and 3 and will have good rigidity.

Selon l'invention, les traverses 25 seront munies d'une vi- r ole carrée 26 à leurs extrémités telles qu'illustrées à la figure 8.According to the invention, the crosspieces 25 will be provided with a square flange 26 at their ends as illustrated in FIG. 8.

En outre, on peut avantageusement prévoir que le gousset 8 inférieur soit pourvu d'un orifice de vidange 27 tel qu'illustré à la figure 9. Cet orifice permettra de vider le liquide contenu dans la poche 1.In addition, provision can advantageously be made for the lower gusset 8 to be provided with a drainage orifice 27 as illustrated in FIG. 9. This orifice will make it possible to empty the liquid contained in the bag 1.

La figure 10 illustre une palette 28 destinée au transport de conditionnement parallélépipédique de l'invention notamment ceux destinés au transport de fluide. La palette 28 présentera une surface 29 de même forme que la base du conditionnement de la présente invention toutefois avec des dimensions légèrement supérieures. Cette palette 28 est avantageusement munie de pieds 30 qui permettent de la surélever et facilitent sa manutention au moyen de chariots élévateurs.FIG. 10 illustrates a pallet 28 intended for the transport of parallelepiped packaging of the invention, in particular those intended for the transport of fluid. The pallet 28 will have a surface 29 of the same shape as the base of the packaging of the present invention, however with slightly larger dimensions. This pallet 28 is advantageously provided with feet 30 which allow it to be raised and facilitate its handling by means of forklifts.

En outre, la palette 28 est équipée de pièces de tissu 31 munies de sangles 32 qui permettent lorsqu'elles sont rabattues de couvrir la surface 29 de la palette 28.In addition, the pallet 28 is equipped with pieces of fabric 31 provided with straps 32 which, when folded down, cover the surface 29 of the pallet 28.

Dans ces conditions, le transport d'un conditionnement vide est illustré à la figure Il dans laquelle la palette 28 est chargée de la poche vide 1 ainsi que tous les éléments qui assurent son maintien en forme tels qu'éléments de conformation et autres. Cet ensemble est immobilisé sur la surface de la palette par l'intermédiaire des pièces de tissu 31 reliées entre elles par des sangles 32.Under these conditions, the transport of an empty packaging is illustrated in FIG. 11 in which the pallet 28 is loaded with the empty bag 1 as well as all the elements which ensure its maintenance in shape such as shaping elements and others. This assembly is immobilized on the surface of the pallet by means of the pieces of fabric 31 connected to one another by straps 32.

La figure 12 illustre la poche 1 de conditionnement des liquides munie de ces plaques de conformation 3 et 7 elle -même renforcée par des traverses 25. Ce montage étant réalisé selon le procédé décrit précédemment, la dite poche est mise en place sur la palette 28 telle qu'illustrée à la figure 13. Des montants profilés 33 sont alors mis en place dans les viroles 26 des traverses 25, ce qui permet de ceinturer la poche 1 à l'aide des traverses 25. En outre, les montants profilés 33 viennent s'emboîter dans les pieds 30 de la palette 28.FIG. 12 illustrates the bag 1 for packaging liquids provided with these shaping plates 3 and 7, itself reinforced by crosspieces 25. This assembly being carried out according to the method described above, said bag is placed on the pallet 28 as illustrated in FIG. 13. Profiled uprights 33 are then placed in the ferrules 26 of the crosspieces 25, which makes it possible to surround the pocket 1 using the crosspieces 25. In addition, the uprights profiles 33 fit into the feet 30 of the pallet 28.

La poche 1 est immobilisée sur la palette 28 à l'aide des pièces de tissu 31 dont les sangles 32 sont fixées sur les traverses latérales 25.The pocket 1 is immobilized on the pallet 28 using pieces of fabric 31 whose straps 32 are fixed on the lateral crosspieces 25.

Les montants 33 seront de hauteur supérieure à celle de la poche 1, ainsi il est possible de superposer des palettes remplies sans comprimer les poches inférieures.The uprights 33 will be higher than that of the pocket 1, so it is possible to superimpose filled pallets without compressing the lower pockets.

Selon un autre mode préférentiel de réalisation de la présente invention, celle-ci peut s'appliquer au conditionnement de fluide sous vide. On connaît notamment dans le domaine vinicole les difficultés rencontrées pour le transport et le stockage de vin. En effet, cette boisson s'oxyde rapidement en contact de l'air et seul un conditionnement sous vide permet de disposer d'une durée de stockage relativement importante.According to another preferred embodiment of the present invention, it can be applied to the packaging of fluid under vacuum. Particularly in the wine sector, the difficulties encountered in transporting and storing wine are known. Indeed, this drink oxidizes quickly in contact with air and only vacuum packaging allows for a relatively long storage period.

Les exemples de réalisation donnés précédemment ne permettent pas de s'appliquer facilement au conditionnement de produits sous vide étant donné que la poche est mise en forme préalablement à son remplissage.The exemplary embodiments given above do not make it easy to apply to the packaging of products under vacuum, since the bag is shaped before it is filled.

Selon le procédé de conditionnement qui est décrit ultérieurement, il est possible de transporter et stocker un liquide oxydable sans que ce dernier soit mis à un moment quelconque en contact avec l'atmosphère.According to the packaging process which is described later, it is possible to transport and store an oxidizable liquid without the latter being brought into contact with the atmosphere at any time.

Les figures 14a, b, c, d et e illustrent les différentes phases initiales du procédé de conditionnement parallélépipédique sous vide.Figures 14a, b, c, d and e illustrate the various initial phases of the parallelepipedic vacuum packaging process.

Selon le procédé, on utilise une poche 1 formée d'une feuille repliée sur elle-même ou de deux feuilles plaquées l'une contre l'autre et soudées sur leur pourtour 34 de façon étanche.According to the method, use is made of a pocket 1 formed of a sheet folded back on itself or of two sheets pressed against one another and welded around their periphery 34 in a sealed manner.

Le choix du matériau utilisé pour la confection de la poche 1 est particulièrement important et doit présenter des caractéristiques d'étanchéité à l'égard des liquides et des gaz. De bons résultats ont été obtenus en utilisant une feuille d'aluminium doublée d'une pellicule plastifiée autorisant le contact avec des produits alimentaires.The choice of material used to make the bag 1 is particularly important and must have sealing characteristics with regard to liquids and gases. Good results have been obtained by using an aluminum foil lined with a plastic film allowing contact with food products.

Il est important également de noter que la poche doit être entièrement vide, c'est-à-dire lors de la réalisation de la poche, il est nécessaire de chasser l'air prisonnier entre les deux poches de façon à ce que une fois soudées,les parois composant la poche 1 soient plaquées l'une contre l'autre en raison de la dépression régnant entre lesdites parois.It is also important to note that the pocket must be completely empty, that is to say when making the pocket, it is necessary to expel the air trapped between the two pockets so that once welded , the walls making up the pocket 1 are pressed against each other due to the vacuum prevailing between said walls.

Il est possible d'envisager une utilisation d'une poche présentant un insert de remplissage,toutefois, il sera souhaitable que cet insert soit operculé de façon à ce que le vide créé en coussin de la poche puisse être conservé.It is possible to envisage using a pocket having a filling insert, however, it will be desirable for this insert to be sealed so that the vacuum created as a cushion of the pocket can be preserved.

Selon l'invention, on rigidifie une partie de la poche souple 1 aux formes d'une face du volume parallélépipédique développé à obtenir après remplissage, ceci à l'aide d'un panneau de conformation.According to the invention, a part of the flexible bag 1 is stiffened to the shapes of a face of the developed parallelepiped volume to be obtained after filling, this using a shaping panel.

Dans les exemples illustrés précédemment, le procédé de conditionnement de la présente invention prévoyait la rigidification des parties de la poche correspondant aux différentes faces latérales du conditionnement parallélépipédique à obtenir. Pour cela, on utilisait quatre panneaux de conformation plaqués sur les quatres faces latérales de la poche mise en forme de parallélépipède.In the examples illustrated above, the packaging method of the present invention provided for the stiffening of the parts of the bag corresponding to the different lateral faces of the parallelepiped packaging to be obtained. For this, we used four shaping panels plated on the four side faces of the pocket shaped parallelepiped.

Dans l'exemple présent, la rigidification envisagée ne vise qu'une seule face du parallélépipède, il s'agit du fond de la poche.In the present example, the envisaged stiffening only targets one side of the parallelepiped, this is the bottom of the pocket.

Etant donné toutefois qu'il s'agit d'une poche initialement mise sous vide, certaines particularités sont à mettre en oeuvre pour obtenir la rigidification du fond de la poche.However, since this is a bag initially placed under vacuum, certain features have to be implemented in order to stiffen the bottom of the bag.

Tout d'abord, le panneau de conformation 35 utilisé, présente une arête 36 de pliage, telle qu'illustrée à la figure 14b.First of all, the shaping panel 35 used has a folding edge 36, as illustrated in FIG. 14b.

Par pliage, le panneau de conformation peut ainsi être placé à cheval à la partie inférieure de la poche 1 tel qu'illustré aux figures 14a et 14c.By folding, the shaping panel can thus be placed astride the lower part of the pocket 1 as illustrated in FIGS. 14a and 14c.

Il en résulte que la mise en place et la fixation du panneau de conformation sur la poche 1 ne demandent préalablement aucun pliage de celle-ci. La fixation du panneau de conformation 35 sur la poche 1 peut être réalisée notamment par un collage.It follows that the establishment and fixing of the shaping panel on the pocket 1 does not require any folding of the latter beforehand. The fixing of the shaping panel 35 on the pocket 1 can be carried out in particular by gluing.

Le panneau de conformation 35 est ainsi fixé en partie sur chacune des faces composant la poche souple 1.The shaping panel 35 is thus partially fixed on each of the faces making up the flexible bag 1.

Il est souhaitable d'utiliser un panneau de conformation de forme rectangulaire qui formera la base du parallélépipède de conditionnement à obtenir. L'arête de pliage 36 sera disposée de préférence au centre du panneau de conformation 35.It is desirable to use a rectangular shaped shaping panel which will form the base of the packaging parallelepiped to be obtained. The folding edge 36 will preferably be placed in the center of the shaping panel 35.

La largeur de la poche 1 sera de préférence supérieure à la dimension du panneau de conformation 35 et par conséquent, la poche 1 dépassera de part et d'autre du panneau 35.The width of the pocket 1 will preferably be greater than the dimension of the shaping panel 35 and consequently, the pocket 1 will protrude on either side of the panel 35.

Une fois le panneau fixé sur la poche 1, on ouvre à plat le dit panneau de conformation 35 qui forme la base du conditionnement tel qu'illustré à la figure 14d.Once the panel fixed on the pocket 1, said flat panel 35 is opened flat which forms the base of the packaging. as shown in Figure 14d.

Cette ouverture à plat du panneau de conformation se fait jusqu'à obtenir une mise en place de la poche 1 en forme d'équerre sur le panneau de conformation 35 tel qu'illustrée à la figure 14e.This flat opening of the shaping panel is done until the pocket 1 is placed in the form of a square on the shaping panel 35 as illustrated in FIG. 14e.

En raison du vide existant dans la poche 1, les parois composant la poche 1 restent plaquées l'une contre l'autre et l'ouverture à plat du panneau 35 oblige les parois de la poche 1 à rester plaquées contre le panneau.Due to the vacuum existing in the pocket 1, the walls making up the pocket 1 remain pressed against each other and the flat opening of the panel 35 forces the walls of the pocket 1 to remain pressed against the panel.

Après avoir effectué ces différentes opérations, on retrouve une mise en forme générale du conditionnement tel qu'illustré à la figure 15. La poche 1 se compose d'une partie de ses parois 37 et 38 plaquées contre le panneau de conformation 35 qui forme la base du conditionnement et d'une partie centrale 39 dominant la base et qui comporte des repliages en accordéon illustrés en détail à la figure 4 de ses chants latéraux 40.After having carried out these various operations, there is a general shaping of the packaging as illustrated in FIG. 15. The bag 1 consists of a part of its walls 37 and 38 pressed against the shaping panel 35 which forms the base of the packaging and of a central part 39 dominating the base and which comprises accordion folds illustrated in detail in FIG. 4 of its lateral edges 40.

Ce repliage 40 est essentiellement dû au fait que les dimensions du panneau de conformation 35 sont inférieures aux dimensions de la poche 1.This folding 40 is essentially due to the fact that the dimensions of the shaping panel 35 are smaller than the dimensions of the pocket 1.

Cet écart dimensionnel provoque en outre la création de cornettes intérieures 41 et 42.This dimensional deviation also causes the creation of interior cornets 41 and 42.

Ces cornettes 41 et 42 seront rabattues autour du panneau de conformation 35 tel qu'illustré à la figure 16. Ces cornettes 41 et 42 seront fixées sur le panneau 39.These horns 41 and 42 will be folded around the shaping panel 35 as illustrated in FIG. 16. These horns 41 and 42 will be fixed on the panel 39.

Pour le transport, la partie saillante 39 de la poche 1 pourra être rabattue contre le panneau 35 qui forme le fond du conditionnement pour minimiser le volume occupé tel qu'illustré à la figure 17. Si la partie 39 de la poche 1 était de grande hauteur, il est possible d'effectuer un repliage en accordéon avant de la rabattre sur le panneau de base pour minimiser la surface au sol occupée.For transport, the projecting part 39 of the bag 1 can be folded against the panel 35 which forms the bottom of the packaging to minimize the volume occupied as illustrated in FIG. 17. If the part 39 of the bag 1 was large height, it is possible to perform an accordion folding before folding it over the base panel to minimize the floor space occupied.

Pour le remplissage de la poche 1, on place l'ensemble de la poche 1 et le panneau de conformation 35 avec les cornettes 41 et 42 repliées dans un conteneur rigide 43 tel qu'illustré à la figure 18.For the filling of the bag 1, the whole of the bag 1 and the shaping panel 35 are placed with the cornettes 41 and 42 folded in a rigid container 43 as illustrated in FIG. 18.

Le conteneur 43 rigide utilisé présentera une embase de dimensions sensiblement identiques à celles du panneau de conformation 35, de façon à pouvoir recevoir celui-ci dans le fond du conteneur.The rigid container 43 used will have a base of dimensions substantially identical to those of the shaping panel 35, so as to be able to receive the latter in the bottom of the container.

L'extrémité d'une des cornettes supérieures 44 sera raccordée de façon étanche à une conduite 45 de remplissage. Il peut également être envisagé l'utilisation d'un insert fileté sur la poche 1 qui soit raccordé à une tuyauterie de remplissage sous vide.The end of one of the upper horns 44 will be tightly connected to a filling pipe 45. It is also possible to envisage the use of a threaded insert on the pocket 1 which is connected to a vacuum filling pipe.

On peut noter que selon ce procédé de réalisation, le remplissage de la poche 1 est réalisé en l'absence totale d'air.It can be noted that according to this production method, the filling of the bag 1 is carried out in the total absence of air.

Puisque la poche 1 est disposée dans un conteneur rigide 43, et qu'elle présente une base mise en forme par la présence du panneau de conformation 35, durant son remplissage, la poche 1 se développe au fur et à mesure de l'introduction du liquide et épouse parfaitement le profil des faces internes du conteneur 43.Since the pocket 1 is placed in a rigid container 43, and that it has a base shaped by the presence of the shaping panel 35, during its filling, the pocket 1 expands as the introduction of the liquid and perfectly matches the profile of the internal faces of the container 43.

Le conditionnement se développe selon une forme parallélépipédique qui prend naissance à partir de la base c'est-à-dire du panneau de conformation 35 pour s'élever progressivement lors du remplissage.The packaging develops in a parallelepiped shape which originates from the base, that is to say from the conformation panel 35 to rise gradually during filling.

Lorsque la poche estremplie, on scelle l'orifice de remplissage de façon étanche, soit par soudure ou par bouchon. Les cornettes supérieures 44 et 46 peuvent être alors rabattues sur la partie supérieure de la poche de forme parallélépipédique 1 telle que illustrée à la figure 19.When the bag is filled, the filling orifice is sealed tightly, either by welding or by plug. The upper horns 44 and 46 can then be folded over the upper part of the pocket of parallelepipedal shape 1 as illustrated in FIG. 19.

On pourra avantageusement utiliser comme conteneur rigide 43, une palette à parois amovibles d'un modèle analogue à celui présenté initialement à la figure 13. Cette réalisation offre l'avantage de pouvoir être démontée afin d'occuper un volume minimal à vide et par ailleurs, il est possible de gerber les conteneurs remplis pour réduire la surface au sol occupée.Advantageously, a pallet with removable walls of a model similar to that initially presented in FIG. 13 can be used as rigid container 43. This embodiment offers the advantage of being able to be dismantled in order to occupy a minimum empty volume and moreover , it is possible to stack the filled containers to reduce the floor space occupied.

D'autres mises en oeuvre de la présente invention , à la portée de l'Homme de l'Art, auraient pu être adoptées sans pour autant sortir du cadre de celle-ci.Other implementations of the present invention, within the reach of ordinary skill in the art, could have been adopted without departing from the scope thereof.
