- the base 4 consists of a material chosen such that it supports the load that it will carry during filling.
- the shape of this base is defined by the empty space that one wishes to find at the base of the container once formed.
- the plastic strips must be arranged at the edges of the empty spaces of the base 4. When the second envelope is circled, they will thus delimit the free space under the container.
- the base is itself placed on a vibrating table.

Description
L'invention concerne un procédé de conditionnement d'une substance solide à l'état divisé, permettant d'être transportée sans l'ajout d'un élément supplémentaire jouant un rôle d'interface entre l'emballage et le transporteur.The invention relates to a method for packaging a solid substance in the divided state, making it possible to be transported without the addition of an additional element acting as an interface between the packaging and the transporter.
Ce procédé s'applique notamment au conditionnement et au transport de fibres de verre coupées.This process applies in particular to the packaging and transport of cut glass fibers.
Actuellement, ce type de produit est transporté dans des containers ou caissons. Ces containers ont de préférence une forme qui permet de les empiler. Il est ainsi possible de les stocker avec un encombrement minimum. Ces containers sont généralement constitués d'une enveloppe souple que l'on place au sein d'un container en un matériau plus résistant et de préférence léger. On utilise généralement un container en carton qui permet ainsi de limiter le poids de l'emballage.Currently, this type of product is transported in containers or boxes. These containers preferably have a shape which allows them to be stacked. It is thus possible to store them with a minimum bulk. These containers generally consist of a flexible envelope which is placed within a container made of a more resistant and preferably light material. A cardboard container is generally used which thus makes it possible to limit the weight of the packaging.
Ces emballages sont tout à fait appropriés à ce type de produits pour leur stockage ainsi que pour leur transport. Mais en ce qui concerne le transport, il est nécessaire de rajouter un élément supplémentaire. On utilise généralement des palettes que l'on place sous le container et qui s'adapte à la base du container. Ces palettes sont constituées de lattes de bois qui sont assemblées de façon à offrir un espace libre permettant le passage des fourches d'un chariot élévateur, par exemple, de façon à soulever et à déplacer le container. Il est donc nécessaire de disposer d'une palette pour chacun des containers. Cela entraîne donc une augmentation des coûts d'emballage. D'autre part, cet élément supplémentaire augmente de façon non négligeable le poids de l'emballage. Cela peut éventuellement limiter la charge de produit transportable par un camion.These packages are perfectly suitable for this type of product for their storage as well as for their transport. But with regard to transport, it is necessary to add an additional element. Pallets are generally used which are placed under the container and which adapts to the base of the container. These pallets consist of wooden slats which are assembled so as to provide a free space allowing the passage of the forks of a forklift, for example, so as to lift and move the container. It is therefore necessary to have a pallet for each container. This therefore leads to an increase in packaging costs. On the other hand, this additional element increases not the weight of the packaging is negligible. This may possibly limit the load of product transportable by a truck.
L'invention a pour but un procédé de conditionnement du type container, dont la forme permet un stockage avec un minimum d'encombrement et dont le transport peut s'effectuer sans élément supplémentaire.The object of the invention is to provide a container-type packaging method, the shape of which allows storage with a minimum of bulk and the transport of which can be carried out without any additional element.
Il est connu du document FR-A-2 537 091 de réaliser un sac de grande capacité destiné à contenir des matériaux solides ou liquides, entouré de sangles dont le serrage forme un rétreint dont la hauteur est au moins égale à la hauteur des fourches d'un chariot élévateur.It is known from document FR-A-2 537 091 to produce a large capacity bag intended to contain solid or liquid materials, surrounded by straps whose tightening forms a constriction whose height is at least equal to the height of the forks. 'a forklift.
Des études ont été menées en ce sens et ont conduit à un nouveau type de conditionnement. Les inventeurs proposent un procédé défini en substance dans la revendication 1 et permettant de communiquer une forme voulue au conditionnement, plus particulièrement à sa base. De cette façon, il est possible de définir une forme à la base de l'emballage permettant le passage des fourches d'un chariot élévateur. Dans le souci de ne pas augmenter les coûts de l'emballage, les inventeurs ne préconisent non pas un emballage réalisé à partir de matière rigide possédant une telle forme avant son utilisation mais un emballage réalisé uniquement à partir de matière souple auquel on donnera cette forme durant la phase de remplissage.Studies have been carried out in this direction and have led to a new type of conditioning. The inventors propose a process defined in substance in
Selon l'invention, le problème posé par l'ajout d'un élément supplémentaire, tel qu'une palette, pour le transport de container pour le conditionnement d'une substance solide à l'état divisé est résolu par un procédé de conditionnement pour ce type de substance au sein d'une enveloppe souple, de forme prédéterminée, qui consiste à remplir cette enveloppe constituée d'une matière étanche, la base de ladite enveloppe reposant partiellement sur un socle amovible d'une forme telle que le socle définit, après retrait, un espace libre sous l'enveloppe, à fermer hermétiquement l'enveloppe après avoir réalisé un vide partiel puis à désolidariser l'enveloppe du socle.According to the invention, the problem posed by the addition of an additional element, such as a pallet, for the transport of container for the packaging of a solid substance in the divided state is resolved by a packaging process for this type of substance within a flexible envelope, of predetermined shape, which consists in filling this envelope made of a waterproof material, the base of said envelope partially resting on a removable base of a shape such as the base defines, after removal, a free space under the envelope, hermetically closing the envelope after having produced a partial vacuum and then separating the envelope from the base.
De cette façon, après avoir fait le vide et en le maintenant, il est possible de conserver la forme communiquée par le socle à l'enveloppe souple même après les avoir désolidarisés l'un de l'autre. L'enveloppe souple possédant une forme prédéterminée, telle que des arêtes préformées, on obtient une forme globale désirée lors de la mise sous vide.In this way, after making the vacuum and maintaining it, it is possible to preserve the shape communicated by the base to the flexible envelope even after having separated them from one another. Since the flexible envelope has a predetermined shape, such as preformed edges, a global shape is obtained which is desired during vacuuming.
Dans un des modes de réalisation, on utilise un socle délimitant une zone en creux qui se prolonge sur au moins un des côtés de la base de ladite enveloppe remplie.In one of the embodiments, a base is used delimiting a hollow area which extends over at least one of the sides of the base of said filled envelope.
Selon l'invention, on obtient ainsi un container chargé d'un produit tel que de la fibre de verre coupée, dont la forme générale par exemple parallélépipédique, permet un stockage aisé et dont la base présente au moins une ouverture laissant un passage pour les fourches d'un chariot élévateur. On utilise avantageusement un socle en forme de croix dont les branches se prolongent jusqu'aux bords des côtés de la base de l'enveloppe remplie.According to the invention, a container is thus obtained loaded with a product such as cut glass fiber, the general shape of which, for example parallelepiped, allows easy storage and the base of which has at least one opening leaving a passage for the forks of a forklift. Advantageously, a cross-shaped base is used, the branches of which extend to the edges of the sides of the base of the filled envelope.
Il est ainsi possible de pouvoir accéder au container par n'importe quel côté et de le transporter sur les fourches d'un chariot élévateur.It is thus possible to be able to access the container from any side and to transport it on the forks of a forklift.
Lors du remplissage, il faut veiller à ce que l'enveloppe souple soit bien remplie avant de faire le vide. Il est en effet intéressant de bien la remplir de façon à ce qu'en faisant le vide, on obtienne une forme bien homogène. Pour cela, il est possible de tasser la substance lors du remplissage.When filling, make sure that the flexible envelope is well filled before creating a vacuum. It is indeed interesting to fill it well so that by making the vacuum, we obtain a very homogeneous shape. For this, it is possible to pack the substance during filling.
Selon l'invention, on utilise de préférence un socle animé d'un mouvement vibratoire. Cette technique permet d'optimiser le remplissage.According to the invention, preferably using a base animated by a vibratory movement. This technique optimizes the filling.
Le container ainsi obtenu peut présenter certains risques dans le cas de manipulations brusques ou violentes. On peut en effet craindre dans certaines conditions une déchirure de l'enveloppe souple. Ce type d'incident pourrait entraîner d'une part une perte de la charge et d'autre part une déformation complète du container, la déchirure ayant provoqué une arrivée d'air.The container thus obtained can present certain risks in the case of rough or violent handling. One can indeed fear under certain conditions a tear of the flexible envelope. This type of incident could lead on the one hand to a loss of load and on the other hand to a complete deformation of the container, the tearing having caused an air intake.
Une variante selon l'invention consiste à entourer l'enveloppe étanche par une enveloppe de protection. Ceci se fait de préférence dès le stade du remplissage. Il est avantageux que cette seconde enveloppe épouse la forme prise par la première de façon à conserver l'aspect du container obtenu en réalisant un vide partiel.A variant according to the invention consists in surrounding the sealed envelope with a protective envelope. This is preferably done from the filling stage. It is advantageous for this second envelope to conform to the shape taken by the first so as to preserve the appearance of the container obtained by achieving a partial vacuum.
Selon l'invention, après remplissage et réalisation du vide partiel, on maintient l'enveloppe de protection contre l'enveloppe étanche à l'aide de sangles.According to the invention, after filling and creation of the partial vacuum, the protective envelope is kept against the sealed envelope using straps.
De préférence, ces sangles sont disposées de manière à ce que l'enveloppe de protection épouse la forme de l'enveloppe étanche.Preferably, these straps are arranged so that the protective envelope matches the shape of the waterproof envelope.
On obtient ainsi un container apte au stockage et au transport d'une substance solide à l'état divisé. La première enveloppe qui est étanche permet de lui donner sa forme et la seconde enveloppe apporte une meilleure résistance lors de la manutention.A container is thus obtained capable of storing and transporting a solid substance in the divided state. The first envelope which is waterproof makes it possible to give it its shape and the second envelope provides better resistance during handling.
L'invention concerne également un container obtenu par le procédé selon l'invention, ce container se compose essentiellement d'une enveloppe souple, rempli d'une substance solide à l'état divisé, dont l'enveloppe est étanche et comporte un ajutage à son sommet, ledit container présentant une forme générale par exemple parallélépipédique, et plus particulièrement à sa base, une forme en creux affleurant les bords.The invention also relates to a container obtained by the process according to the invention, this container essentially consists of a flexible envelope, filled with a solid substance in the divided state, the envelope of which is sealed and has a nozzle at its top, said container having a general shape, for example parallelepipedal, and more particularly at its base, a hollow shape flush with the edges.
D'une façon préférée, l'enveloppe est constituée d'un produit complexe associant matière plastique et feuille d'aluminium.In a preferred manner, the envelope consists of a complex product associating plastic material and aluminum foil.
Dans une variante, le container comporte une seconde enveloppe, de protection, qui entoure l'enveloppe étanche et est maintenue par des sangles.In a variant, the container comprises a second protective envelope which surrounds the sealed envelope and is held by straps.
De façon préférée, cette seconde enveloppe est constituée d'une toile de propylène tissé et les sangles sont des feuillards en plastique.Preferably, this second envelope is made of a woven propylene fabric and the straps are plastic strips.
Ce container permet donc par sa forme, par exemple parallélépipédique, un stockage aisé. La forme qui lui est donnée à sa base va permettre son transport. Ceci est obtenu grâce à l'utilisation d'une première enveloppe étanche qui permet de faire le vide.This container therefore allows for its shape, for example parallelepiped, easy storage. The shape given to it at its base will allow its transport. This is achieved through the use of a first waterproof envelope which allows to create a vacuum.
La seconde enveloppe qui est plus résistante permet de protéger la première lors d'utilisations présentant d'éventuels risques.The second envelope which is more resistant makes it possible to protect the first during uses presenting possible risks.
Il est également possible d'avoir fixé au préalable des courroies sur la seconde enveloppe.It is also possible to have previously fixed belts on the second envelope.
Selon l'invention, la seconde enveloppe comporte au moins une courroie faisant office de poignée à son sommet.According to the invention, the second envelope comprises at least one belt acting as a handle at its top.
Les courroies sont avantageusement disposées au quatre coins de la seconde enveloppe. Ces sangles peuvent notamment être utilisées lors du remplissage où elles permettent de maintenir l'enveloppe.The belts are advantageously arranged at the four corners of the second envelope. These straps can in particular be used during filling where they allow the envelope to be maintained.
Le container ainsi obtenu présente également d'autres avantages du fait que l'on n'utilise pas d'éléments supplémentaires. Tout d'abord, cet élément n'étant pas nécessaire, le coût de l'emballage est diminué. D'autre part, l'élément étant bien souvent une palette en bois, la masse de l'emballage diminue ce qui peut permettre, par exemple, d'augmenter la charge d'un camion.The container thus obtained also has other advantages of not using additional elements. First of all, this element not being necessary, the cost of the packaging is reduced. On the other hand, the element being very often a wooden pallet, the mass of the packaging decreases which can allow, for example, to increase the load of a truck.
Un autre avantage concerne le recyclage de ces emballages. Les enveloppes sont très facilement reprises par le fournisseur chez le client et sont d'un faible encombrement une fois vide. Par contre, lorsqu'il faut récupérer des éléments tels que des palettes en bois chez un client, cela nécessite un transport spécial du fait de leur encombrement.Another advantage concerns the recycling of this packaging. The envelopes are very easily picked up by the supplier from the customer and are compact when empty. On the other hand, when it is necessary to recover elements such as wooden pallets from a customer, this requires special transport because of their bulk.
D'autres détails et caractéristiques avantageuses de l'invention ressortent ci-après de la description d'un exemple de réalisation de l'invention, décrit en référence aux figures, qui représentent :
- figure 1 : un exemple de container obtenu par le procédé selon l'invention,
- figure 2 : un exemple de socle selon l'invention.
- FIG. 1: an example of a container obtained by the method according to the invention,
- Figure 2: an example of a base according to the invention.
Sur la figure 1, un container 1 obtenu par le procédé selon l'invention a été schématiquement représenté. La première enveloppe, qui est étanche, n'est pas représentée sur ce schéma. Par contre, on observe bien la forme parallélépipédique qu'il est possible d'obtenir lorsque l'on fait le vide. Il est bien évident que cette forme ne s'obtient pas si facilement. Il est possible au moment de la réalisation de cette enveloppe de lui donner une forme prédéterminée. C'est-à-dire que les arêtes formant par exemple le parallélépipède après le remplissage sont déjà formées sur l'enveloppe.In Figure 1, a
Une autre possibilité est de contenir cette enveloppe lors du remplissage, dans un cadre support qui donne la forme parallélépipédique à l'enveloppe. Le remplissage de cette enveloppe se fait par tout type de moyens connus de l'homme du métier, permettant de disposer les fibres de verre coupées sans les endommager. Une fois la première enveloppe bien remplie et après lui avoir donné la forme, on fait le vide au sein de cette enveloppe de sorte qu'elle conserve cette forme. L'action du vide provoque une rétractation de cette enveloppe autour de la charge. On assiste donc à une compression de la charge et une augmentation de sa compacité. Cela permet de conserver la forme, par exemple parallélépipédique, et notamment les contours donnés à sa base car cette action du vide rigidifie les parois du container ainsi obtenu.Another possibility is to contain this envelope during filling, in a support frame which gives the rectangular shape to the envelope. The filling of this envelope is done by any type of means known to those skilled in the art, making it possible to arrange the cut glass fibers without damaging them. Once the first envelope is well filled and after giving it the shape, we create a vacuum within this envelope so that it keeps this shape. The action of the vacuum causes this envelope to shrink around the load. There is therefore a compression of the load and an increase in its compactness. This keeps the shape, for example parallelepiped, and in particular the contours given at its base because this action of the vacuum stiffens the walls of the container thus obtained.
Selon l'une de ces techniques, il est possible d'obtenir une forme parallélépipédique. Pour obtenir la forme désirée à la base du container, c'est-à-dire une forme permettant le passage d'une ou plusieurs fourches d'un chariot élévateur, sous le container, on utilise un socle 4 qui sera décrit par la suite.According to one of these techniques, it is possible to obtain a parallelepiped shape. To obtain the desired shape at the base of the container, that is to say a shape allowing the passage of one or more forks of a forklift, under the container, use a base 4 which will be described later .
L'orifice de l'enveloppe est ensuite fermé hermétiquement par tout moyen connu de l'homme du métier, tel qu'une soudure ou un scellage.The opening of the envelope is then hermetically closed by any means known to those skilled in the art, such as welding or sealing.
La seconde enveloppe 2 vient ensuite recouvrir le container ainsi formé. La seconde enveloppe n'a pas besoin d'être étanche mais elle est choisie dans un matériau résistant afin de protéger la première enveloppe.The
L'enveloppe 2 est maintenue autour de l'enveloppe étanche par au moins quatre feuillards en plastique 3. Ces feuillards en plastique 3 sont disposés de telle façon qu'ils permettent de plaquer la seconde enveloppe 2 sur la première. Pour cela, ils sont placés de façon à délimiter la base du container 1 déjà formée par le socle 4.The
Au sommet du container ainsi formé et donc sur la seconde enveloppe, on fixe des poignées 5 par tout moyen connu de l'homme du métier.At the top of the container thus formed and therefore on the second envelope, handles 5 are fixed by any means known to those skilled in the art.
Cette fixation peut se faire avant mise en forme du container, voire même lors de la fabrication de l'enveloppe.This fixing can be done before the container is shaped, or even during the manufacture of the envelope.
Ces poignées 5 peuvent servir pour maintenir l'enveloppe lors du remplissage. Il est dans ce cas impératif de les avoir fixées avant.These
Sur la figure 2, nous avons représenté un exemple de socle 4.In FIG. 2, we have shown an example of base 4.
Le socle 4 consiste en un matériau choisi tel qu'il supporte la charge qu'il va porter lors du remplissage. La forme de ce socle est définie par l'espace vide que l'on désire trouver à la base du container un fois formé. Sur ce socle, on dispose les feuillards en plastique 3. Ils sont représentés au nombre de quatre mais il est bien entendu possible d'en insérer d'autres suivant les dimensions du container.The base 4 consists of a material chosen such that it supports the load that it will carry during filling. The shape of this base is defined by the empty space that one wishes to find at the base of the container once formed. On this base, there are the plastic strips 3. They are represented four in number but it is of course possible to insert others depending on the dimensions of the container.
Comme décrit précédemment, pour que la seconde enveloppe épouse la forme de la première une fois le vide réalisé, les feuillards en plastique doivent être disposés aux bords des espaces vides du socle 4. Lorsque l'on va cercler la seconde enveloppe, ils vont ainsi délimiter l'espace libre sous le container.As described above, so that the second envelope follows the shape of the first once the vacuum has been created, the plastic strips must be arranged at the edges of the empty spaces of the base 4. When the second envelope is circled, they will thus delimit the free space under the container.
En ce qui concerne les opérations permettant de former le container, il est possible de déposer la seconde enveloppe 2 sur le socle 4 qui viendra recouvrir la première enveloppe une fois formée. On dépose ensuite la première enveloppe et l'on procède au remplissage. Pour faciliter ce remplissage et bien tasser les fibres de verre coupées, le socle est lui-même disposé sur une table vibrante. Cette table n'est pas représentée sur les figures. Elle peut être tout système connu de l'homme du métier. Ce système permet essentiellement de bien remplir la base du container, c'est-à-dire la partie sur laquelle va reposer le container qui va permettre le passage des fourches du chariot élévateur. Il est important d'obtenir un container qui soit bien stable et dont l'espace vide à la base soit le plus régulier possible, notamment sur sa hauteur.Regarding the operations for forming the container, it is possible to deposit the
D'autres variantes de la réalisation décrite sont à la portée de l'homme du métier sans sortir du cadre de l'invention.Other variants of the described embodiment are within the reach of the skilled person without departing from the scope of the invention.
