Description
La présente invention concerne un conteneur souple pour un matériau fluide.The present invention relates to a flexible container for a fluid material.
Par matériau fluide, on entend tout matériau présentant la propriété de s'écouler librement, ou d'épouser la forme de son contenant. Par cette définition, on entend notamment tout matériau liquide, visqueux, mais aussi tout matériau solide sous forme particulaire ou discrète, tels que poudre, granulés, etc...By fluid material is meant any material having the property of flowing freely, or of marrying the shape of its container. By this definition is meant in particular any liquid, viscous material, but also any solid material in particulate or discrete form, such as powder, granules, etc.
Conformément aux documents EP-A-0 247 696 et EP-A-0 347 001, on a décrit un conteneur souple pour matériau fluide, ayant une forme générale tubulaire selon une direction longitudinale ou hauteur, par exemple verticale, et délimitant en section transversale, perpendiculairement à la direction longitudinale, par exemple en section horizontale médiane selon la hauteur, différentes sones de stockage du matériau fluide, dont au moins une zone principale, par exemple une zone centrale de forme octogonale, et au moins quatre zones périphériques, par exemple en forme de triangle équilatéral, distribuées régulièrement à l'extérieur de la zone principale, par exemple aux quatre coins de la zone centrale octogonale. Dans sa partie adjacente à la zone principale, chaque zone périphérique communique avec cette dernière, en ce qui concerne ou vis-à-vis du matériau stocké, selon une pluralité d'orifices de communication, distribués selon l'extension longitudinale du conteneur, et assurant le remplissage des zones périphériques à partir de la zone centrale. Et, de manière traditionnelle, un tel conteneur peut comprendre, à l'une de ses extrémités selon la direction longitudinale, par exemple à son extrémité supérieure, un moyen de remplissage, tel qu'une goulotte, et à son autre extrémité, par exemple à son extrémité inférieure, un moyen de vidage, tel qu'une goulotte.In accordance with documents EP-A-0 247 696 and EP-A-0 347 001, a flexible container for fluid material has been described, having a generally tubular shape in a longitudinal direction or height, for example vertical, and delimiting in cross section , perpendicular to the longitudinal direction, for example in median horizontal section according to the height, different sound storage areas for the fluid material, including at least one main area, for example a central area of octagonal shape, and at least four peripheral areas, for example in the shape of an equilateral triangle, distributed regularly outside the main area, for example at the four corners of the central octagonal area. In its part adjacent to the main zone, each peripheral zone communicates with the latter, with regard to or vis-à-vis the stored material, according to a plurality of communication orifices, distributed according to the longitudinal extension of the container, and ensuring the filling of the peripheral zones from the central zone. And, in a traditional manner, such a container can comprise, at one of its ends in the longitudinal direction, for example at its upper end, a filling means, such as a chute, and at its other end, for example at its lower end, an emptying means, such as a chute.
De tels conteneurs sont réalisés en général de la manière suivante.Such containers are generally produced in the following manner.
On part d'une paroi souple, dans laquelle on découpe différents flancs rectangulaires, à savoir un premier flanc pour former une enveloppe intérieure délimitant la zone principale, et dont la surface correspond à la surface développée de cette enveloppe intérieure, et au moins quatre autres flancs correspondant à quatre côtés extérieurs du conteneur respectivement. L'enveloppe intérieure comporte une pluralité de panneaux, par exemple huit panneaux de largeur égale, disposés selon la direction longitudinale, les uns perforés, les autres pleins ou étanches vis-à-vis du matériau à stocker, les panneaux perforés alternant avec les panneaux non perforés ou pleins. Les deux lisières de l'enveloppe intérieure sont jointes ou assemblées l'une à l'autre selon la direction longitudinale, pour délimiter la zone de stockage principale ou centrale. Les quatre côtés extérieurs sont assemblés pour partie au contact de l'enveloppe intérieure, par jonction ou liaison de chaque panneau non perforé avec un côté extérieur, selon les deux bords longitudinaux dudit panneau. Les bordures longitudinales libres des côtés extérieurs sont ensuite assemblées deux à deux pour délimiter les zones de stockage périphérique, à l'extérieur de la zone de stockage principale ou centrale, laquelle communique avec les zones périphériques de stockage par les panneaux perforés de l'enveloppe intérieure. Puis on rapporte, aux deux extrémités supérieure et inférieure du corps du conteneur obtenu comme précédemment, respectivement le moyen de remplissage, et le moyen de vidage, et ceci par assemblage de pièces appropriées, par exemple une paroi droite avec goulotte centrale, selon les bordures transversales du contour supérieur et du contour inférieur du corps du conteneur obtenu comme précédemment.We start from a flexible wall, in which we cut different rectangular sides, namely a first side to form an inner envelope delimiting the main area, and whose surface corresponds to the developed surface of this inner envelope, and at least four others sides corresponding to four outer sides of the container respectively. The inner envelope comprises a plurality of panels, for example eight panels of equal width, arranged in the longitudinal direction, some perforated, others solid or sealed with respect to the material to be stored, the perforated panels alternating with the panels unperforated or solid. The two edges of the inner envelope are joined or assembled to each other in the longitudinal direction, to delimit the main or central storage area. The four outer sides are partly assembled in contact with the inner envelope, by junction or connection of each non-perforated panel with an outer side, along the two longitudinal edges of said panel. The free longitudinal edges of the outer sides are then assembled in pairs to delimit the peripheral storage areas, outside the main or central storage area, which communicates with the peripheral storage areas by the perforated panels of the envelope. interior. Then, at the two upper and lower ends of the body of the container obtained as above, the filling means and the emptying means are reported respectively, and this by assembling suitable parts, for example a straight wall with central chute, along the edges transverse of the upper contour and the lower contour of the body of the container obtained as above.
Pour terminer, sur les joints ou liaisons d'assemblage des bordures libres des côtés extérieurs, on fixe à l'extrémité supérieure du conteneur, respectivement des attaches de préhension, consistant en des sangles de levage, adaptées à une préhension par la fourche d'un chariot ou autre moyen mécanique de levage.Finally, on the joints or assembly connections of the free edges of the outer sides, gripping fasteners, respectively, consisting of lifting straps, suitable for gripping by the fork, are fixed to the upper end of the container. a cart or other mechanical lifting means.
Au sens de la description précédente, par paroi souple, on entend toute matière ou matériau en feuille, ou de faible épaisseur par rapport à ses autres dimensions, n'ayant aucune rigidité propre, tel que papier, films ou feuilles en matière plastique, tissus, toiles ou matières textiles, notamment en fibres ou fils d'un matériau plastique tels que le polypropylène, laminés plastiques, etc...Within the meaning of the preceding description, by flexible wall means any material or material in sheet form, or of thin thickness compared to its other dimensions, having no inherent rigidity, such as paper, films or sheets of plastic material, fabrics , fabrics or textile materials, in particular fibers or threads of a plastic material such as polypropylene, plastic laminates, etc.
Au sens de la description précédente, par joint de liaison d'assemblage, on entend tout moyen permettant de réaliser une ligne d'assemblage entre deux bords ou bordures adjacents d'au moins deux éléments distincts de paroi souple, tels que des flancs ou panneaux. Ressortent de cette définition des moyens aussi différents qu'un assemblage par couture, par soudure, collage, etc...Within the meaning of the preceding description, by connection joint of assembly, one understands any means making it possible to carry out an assembly line between two edges or adjacent edges of at least two distinct elements of flexible wall, such as sides or panels . This definition means as different as an assembly by sewing, welding, gluing, etc.
Les conteneurs souples tels que décrits précédemment présentent une fragilité relative au niveau des zones de stockage périphérique et des parois extérieures correspondantes, vis-à-vis, d'une part de la pression exercée par le poids du matériau fluide stocké à cet endroit, et d'autre part des chocs ou autres agressions consécutives à la manipulation, ou au transport des conteneurs pleins ou chargés.The flexible containers as described above have a relative fragility in the peripheral storage areas and the corresponding external walls, vis-à-vis, on the one hand, the pressure exerted by the weight of the fluid material stored at this location, and on the other hand shocks or other aggressions following handling or transporting full or loaded containers.
Par ailleurs, les conteneurs décrits précédemment présentent une complexité, voire des difficultés de réalisation ou production en série. Ainsi, si on réalise les joints d'assemblage par couture, selon la description précédente, il est nécessaire de réaliser au moins huit coutures de l'enveloppe intérieure, à plat et avec une machine à coudre particulière, compte-tenu du montage retenu, et au moins quatre coutures des côtés extérieurs. Compte-tenu des dimensions importantes adoptées pour les conteneurs destinés au transport de charges importantes, ces coutures deviennent un obstacle substantiel à la productivité. Par ailleurs, plus le nombre de coutures est important, plus la fragilité globale ou l'étanchéité du conteneur souple peut être compromise.Furthermore, the containers described above have a complexity, or even difficulties in production or mass production. Thus, if the assembly joints are made by sewing, according to the preceding description, it is necessary to make at least eight seams of the inner envelope, flat and with a particular sewing machine, taking into account the assembly selected, and at least four seams on the outside. Given the large dimensions adopted for containers intended for the transport of large loads, these seams become a substantial obstacle to productivity. Furthermore, the greater the number of seams, the more the overall fragility or the tightness of the flexible container can be compromised.
La présente invention a pour objet un conteneur souple tel que défini précédemment, présentant une bonne résistance au niveau de ses zones de stockage périphérique, et de réalisation industrielle beaucoup plus simple.The present invention relates to a flexible container as defined above, having good resistance in its peripheral storage areas, and much simpler industrial production.
Selon la présente invention, le corps du conteneur comprend au moins quatre éléments tubulaires en paroi souple et continue, délimitant chacun une zone périphérique de stockage, et au moins quatre laizes en paroi souple, reliant de manière fermée les éléments tubulaires entre eux, et délimitant avec ces derniers la zone principale de stockage.According to the present invention, the container body comprises at least four tubular elements in a flexible and continuous wall, each delimiting a peripheral storage area, and at least four widths in a flexible wall, closing the tubular elements together, and delimiting with these the main storage area.
Grâce à l'invention, la paroi extérieure des zones périphériques est obtenue sans joint longitudinal d'assemblage, par exemple sans couture, et peut se conformer selon un contour cylindrique, ce qui toutes choses égales par ailleurs, confère au conteneur une très bonne résistance aux chocs, mais aussi à l'éclatement sous l'effet du poids du matériau strocké.Thanks to the invention, the outer wall of the peripheral zones is obtained without a longitudinal joining joint, for example seamless, and can conform to a cylindrical contour, which, all other things being equal, gives the container very good resistance. to impact, but also to bursting under the effect of the weight of the strocked material.
Pour réaliser un conteneur selon l'invention, il suffit de découper, dans un tube à paroi continue, les éléments tubulaires, de perforer ou découper ces éléments entre deux génératrices, de découper comme précédemment les côtés extérieurs, et d'assembler par des joints longitudinaux les éléments tubulaires et les côtés extérieurs, de telle manière que chaque élément tubulaire soit assemblé à deux côtés extérieurs, situés de part et d'autre dudit élément, selon respectivement deux joints ou liaisons longitudinaux (au sens de la définition précédente), correspondant aux deux génératrices précitées, entre lesquelles sont situées les perforations ou découpes de communication avec la zone principale de stockage. Au surplus, la solution adoptée selon l'invention permet, en ce qui concerne la couture des joints, de réaliser des coutures extérieures et à plat, beaucoup plus aisées que des coutures intérieures par exemple.To make a container according to the invention, it suffices to cut the tubular elements from a continuous wall tube, to perforate or cut these elements between two generators, to cut the outer sides as before, and to assemble by joints longitudinal the tubular elements and the outer sides, such that each tubular element is assembled with two outer sides, situated on either side of said element, respectively according to two joints or longitudinal connections (within the meaning of the preceding definition), corresponding to the two aforementioned generators, between which the perforations or cutouts for communication with the main storage area are located. In addition, the solution adopted according to the invention makes it possible, as far as the seam of the joints is concerned, to make exterior and flat seams, much easier than interior seams for example.
Selon un mode préféré d'exécution de l'invention, le conteneur est pourvu d'attaches de préhension, consistant chacune en un lien conformé selon une anse, disposée à l'extrémité supérieure d'un élément tubulaire correspondant, avec deux branches disposées longitudinalement, et assemblées aux deux joints de liaison dudit élément tubulaire, respectivement.According to a preferred embodiment of the invention, the container is provided with grips, each consisting of a link shaped according to a handle, arranged at the upper end of a corresponding tubular element, with two branches arranged longitudinally , and assembled to the two connecting joints of said tubular element, respectively.
De telles attaches permettent de supporter le conteneur, sans risque de déchirement de sa paroi souple, tout en étant mieux adaptées aux fourches des moyens mécaniques de manutention ou levage.Such fasteners make it possible to support the container, without the risk of tearing its flexible wall, while being better suited to the forks of mechanical means of handling or lifting.

Conformément à la figure 2, un conteneur souple selon l'invention présente une forme générale tubulaire selon une direction longitudinale, ou hauteur, et comprend les éléments suivants en paroi souple :
- un corps (1) constitué par quatre éléments tubulaires (2a) à (2d), et quatre laizes (3a) à (3d) reliant de manière fermée les éléments tubulaires entre eux ; la hauteur de chaque élément tubulaire est substantiellement égale à la longueur de chaque laize de forme rectangulaire ; chaque élément tubulaire (2) délimite à l'intérieur une zone (4) périphérique de stockage, et les laizes (3a) à (3d), avec les éléments tubulaires (2a) à (2d) délimitent une zone principale ou centrale de stockage (5)
- un moyen de remplissage (6), rapporté à l'extrémité supérieure du corps (1), consistant en un panneau souple (7), pourvu en son centre d'une goulotte souple de remplissage (8)
- un moyen de vidage (9), rapporté à l'extrémité inférieure du corps (1), consistant en un panneau souple (10), pourvu en son centre d'une goulotte de vidage (11).
- a body (1) constituted by four tubular elements (2a) to (2d), and four widths (3a) to (3d) connecting the tubular elements to each other in a closed manner; the height of each tubular element is substantially equal to the length of each width of rectangular shape; each tubular element (2) delimits inside a peripheral storage zone (4), and the widths (3a) to (3d), with the tubular elements (2a) to (2d) delimit a main or central storage zone (5)
- filling means (6), attached to the upper end body (1), consisting of a flexible panel (7), provided at its center with a flexible filling chute (8)
- emptying means (9), attached to the lower end of the body (1), consisting of a flexible panel (10), provided at its center with an emptying chute (11).
Comme montré notamment par les figures 3 et 4, tous les éléments en paroi souple identifiés précédemment sont assemblés ou liés les uns aux autres par des joints appropriés, par exemple des coutures, disposés selon la hauteur en ce qui concerne le corps (1), et selon le pourtour extérieur de ce dernier, en ce qui concerne le moyen de remplissage (6) et le moyen de vidage (9), disposés pour l'essentiel transversalement, c'est-à-dire perpendiculairement à la direction longitudinale ou hauteur du conteneur. Pour prendre l'exemple de l'élément tubulaire (2a), il est assemblé de part et d'autre aux deux laizes (3a) et (3d) respectivement, selon deux joints longitudinaux (12a) de liaison, correspondant à deux génératrices de l'élément tubulaire (2a), lesquelles sont disposées dans un plan passant par l'axe de l'élément tubulaire (2a), dans la conformation pleine de ce dernier. C'est entre ces deux génératrices, correspondant comme déjà dit aux deux joints longitudinaux (12a), que sont prévues des perforations ou découpes (13) (visibles sous la référence 13b à la figure 2 pour l'élément tubulaire 2b), assurant la communication de la zone périphérique de stockage (4a) avec la zone principale ou centrale de stockage (5).As shown in particular in FIGS. 3 and 4, all the flexible wall elements identified above are assembled or linked to each other by suitable seals, for example seams, arranged according to the height as regards the body (1), and along the outer periphery of the latter, as regards the filling means (6) and the emptying means (9), arranged essentially transversely, that is to say perpendicular to the longitudinal direction or height of the container. To take the example of the tubular element (2a), it is assembled on either side to the two widths (3a) and (3d) respectively, according to two longitudinal joints (12a) connecting, corresponding to two generatrices of the tubular element (2a), which are arranged in a plane passing through the axis of the tubular element (2a), in the full conformation of the latter. It is between these two generators, corresponding as already said to the two longitudinal joints (12a), that perforations or cutouts (13) are provided (visible under the
Des attaches de préhension (14a) à (14d) sont associées à l'extrémité supérieure des zones périphériques de stockage (2a) à (2d). Comme montré par les figures 2 et 4, chaque attache consiste en un lien conformé selon une anse, (15a) par exemple, disposée à l'extrémité supérieure d'un élément tubulaire correspondant, (2a) par exemple, avec deux branches disposées longitudinalement, par exemple (16a), et assemblées aux deux joints de liaison (12a) du même élément tubulaire (2a), respectivement.Gripping fasteners (14a) to (14d) are associated with the upper end of the peripheral storage areas (2a) to (2d). As shown in Figures 2 and 4, each attachment consists of a link shaped according to a handle, (15a) for example, arranged at the upper end of a corresponding tubular element, (2a) for example, with two branches arranged longitudinally , for example (16a), and assembled to the two connecting joints (12a) of the same tubular element (2a), respectively.
Comme le montre la figure 5, chaque lien ou attache (14) consiste en une bande conformée transversalement en barrette, selon l'extension des deux branches (16) d'assemblage avec un élément tubulaire (2) correspondant. Et les deux bordures opposées (141) et (142) de cette barrette enserrent, grâce à une couture appropriée, le joint de liaison (12) de l'élément tubulaire (2) avec une laize adjacente (3). Une telle disposition permet d'assurer si nécessaire l'étanchéité des joints d'assemblage (12), en se servant de la bande ou du lien correspondant à chaque attache (14) de préhension.As shown in Figure 5, each link or fastener (14) consists of a strip shaped transversely in a bar, according to the extension of the two branches (16) of assembly with a corresponding tubular element (2). And the two opposite edges (141) and (142) of this bar enclose, by means of an appropriate seam, the connection joint (12) of the tubular element (2) with an adjacent width (3). Such an arrangement makes it possible to ensure the sealing of the assembly joints (12) if necessary, by using the strip or the link corresponding to each fastener (14) of gripping.
