Abstract
Description
La présente invention concerne un complexe souple en feuille, son procédé de fabrication, ainsi qu'un emballage comportant un tel complexe.The present invention relates to a flexible sheet complex, its manufacturing process and a package comprising such a complex.
L'invention trouve une application particulièrement avantageuse, mais non exclusive, dans le domaine de l'industrie des emballages.The invention finds a particularly advantageous, but not exclusive, application in the field of the packaging industry.
On connaît du brevet français n° 2 563 809 un emballage tubulaire constitué d'un support cylindrique formé par une feuille de matière plastique, papier, carton, etc, sur laquelle est enroulée et collée une bande de bois tel qu'un contreplaqué en deux plis croisés.French patent No. 2,563,809 discloses a tubular package consisting of a cylindrical support formed by a sheet of plastic material, paper, cardboard, etc., on which is wound and glued a strip of wood such as a plywood in two. cross folds.
La mise en oeuvre de cet emballage tubulaire connu est la suivante: on utilise un gabarit pour enrouler la feuille support dont deux bords sont parallèles à une direction donnée constituée par la génératrice du cylindre, lesdits bords pouvant se chevaucher pour permettre leur liaison par collage ou agrafage. On enroule ensuite sur cette feuille support la bande de bois, en spirale et à spires jointives, en utilisant une colle à chaud ou à froid. On obtient ainsi une meilleure résistance mécanique radiale de l'emballage tubulaire. Toutefois, la réalisation d'un tel emballage est longue et fastidieuse et ne conduit pas à une très bonne résistance mécanique dans la direction de mise en forme, c'est-à-dire la direction de la génératrice du cylindre.The implementation of this known tubular packaging is as follows: a template is used for winding the support sheet, two edges of which are parallel to a given direction constituted by the generatrix of the cylinder, said edges being able to overlap to allow their bonding by gluing or stapling. The wooden strip is then wound on this support sheet, in a spiral and with contiguous turns, using hot or cold glue. Better radial mechanical strength of the tubular packaging is thus obtained. However, the production of such packaging is long and tedious and does not lead to very good mechanical strength in the direction of shaping, that is to say the direction of the generator of the cylinder.
Aussi, le problème technique à résoudre par l'objet de la présente invention est de proposer un complexe souple en feuille, destiné à être mis en forme autour d'une direction donnée, complexe qui serait de mise en oeuvre très simple, facile à fabriquer, et qui offrirait une excellente résistance mécanique dans la direction de formage.Also, the technical problem to be solved by the object of the present invention is to propose a flexible sheet complex, intended to be shaped around a given direction, a complex which would be very simple to implement, easy to manufacture. , and which would provide excellent mechanical strength in the forming direction.
La solution au problème technique posé consiste, selon la présente invention, en ce que ledit complexe comprend une feuille d'un matériau souple sur laquelle est collée au moins une feuille de bois déroulé dont le sens des fibres constitue ladite direction de formage.The solution to the technical problem posed consists, according to the present invention, in that said complex comprises a sheet of flexible material on which is glued at least one sheet of unrolled wood whose fiber direction constitutes said forming direction.
Le complexe souple en feuille de l'invention peut ne comporter qu'une seule feuille de bois déroulé collée sur la feuille support de matière souple : papier, matière plastique, aluminium, mousse ou encore carton, notamment carton alimentaire si ledit complexe est destiné à l'industrie agro-alimentaire.The flexible sheet complex of the invention may comprise only one unrolled sheet of wood glued to the flexible material support sheet: paper, plastic, aluminum, foam or cardboard, especially food cardboard if said complex is intended for food industry.
De même, conformément à l'invention, un emballage est remarquable en ce qu'il comporte un complexe souple en feuille selon l'invention, mis en forme autour de ladite direction de formage de manière à réaliser un volume tubulaire quelconque. On entend par volume tubulaire quelconque un volume cylindrique de révolution ou non, laissant à l'utilisateur le soin de donner à l'emballage la forme qu'il désire. La section dudit volume tubulaire peut donc être quelconque, à savoir circulaire, ovale, carrée, rectangulaire, etc.Similarly, in accordance with the invention, a package is remarkable in that it comprises a flexible sheet complex according to the invention, shaped around said forming direction so as to produce any tubular volume. Any tubular volume is understood to mean a cylindrical volume of revolution or not, leaving it to the user to give the packaging the shape he wishes. The section of said tubular volume can therefore be arbitrary, namely circular, oval, square, rectangular, etc.
La mise en oeuvre du complexe souple en feuille de l'invention est donc extrêmement simple puisqu'il suffit de courber la feuille autour de la direction des fibres du bois, ce qui ne présente aucune difficulté puisque dans ce sens le complexe ne présente qu'une faible résistance mécanique.The implementation of the flexible sheet complex of the invention is therefore extremely simple since it suffices to bend the sheet around the direction of the wood fibers, which presents no difficulty since in this sense the complex only presents low mechanical resistance.
A l'inverse, la Demanderesse a mis en évidence le fait que la résistance mécanique du complexe conforme à l'invention était très élevée dans la direction des fibres du bois, ce qui confère une excellente solidité axiale à l'emballage résultant de la mise en forme dudit complexe autour de cette direction.Conversely, the Applicant has highlighted the fact that the mechanical resistance of the complex according to the invention was very high in the direction of the wood fibers, which gives excellent axial strength to the packaging resulting from the placing in the form of said complex around this direction.
Bine entendu, la résistance mécanique est moindre dans le sens perpendiculaire au plan de la feuille du complexe souple, objet de l'invention, c'est-à-dire dans le sens radiale d'un emballage mis en forme. n faut cependant noter qu'à la suite d'une déformation latérale la feuille de matériau souple, du fait de son élasticité a tendance à ramener la feuille de bois déroulé dans sa position initiale, et à redonner à l'emballage sa forme nominale.Of course, the mechanical strength is lower in the direction perpendicular to the plane of the sheet of the flexible complex, object of the invention, that is to say in the radial direction of a shaped package. However, it should be noted that, following a lateral deformation, the sheet of flexible material, due to its elasticity, tends to return the unrolled sheet of wood to its initial position, and to restore the packaging to its nominal shape.
Enfin, le complexe souple en feuille de l'invention présente l'avantage supplémentaire que les noeuds éventuellement présents dans la feuille de bois déroulé sont collés à la feuille de matériau souple et que, par conséquent, il ne peuvent se détacher de ladite feuille de bois déroulé, évitant ainsi un effet déplaisant à l'oeil.Finally, the flexible sheet complex of the invention has the additional advantage that the knots possibly present in the unrolled sheet of wood are glued to the sheet of flexible material and that, consequently, they cannot be detached from said sheet. peeled wood, thus avoiding an unpleasant effect on the eye.
Selon une autre forme de réalisation de l'invention, une feuille de bois déroulé est collée sur chaque face de ladite feuille de matériau souple, les sens des fibres desdites feuilles de bois déroulé étant disposés parallèlement à la direction de formage, ceci de manière à conserver une bonne souplesse mécanique autour de la direction définie par le sens commun des fibres. Ce type de complexe est particulièrement bien adapté lorsqu'un effet plus esthétique est recherché, notamment en décoration ou dans les emballages de produits de luxe, tels que bouteilles d'alcool, etc.According to another embodiment of the invention, a sheet of unrolled wood is glued to each face of said sheet of flexible material, the directions of the fibers of said sheets of unrolled wood being arranged parallel to the direction of forming, this so as to maintain good mechanical flexibility around the direction defined by the common sense of the fibers. This type of complex is particularly well suited when a more aesthetic effect is sought, in particular in decoration or in the packaging of luxury products, such as bottles of alcohol, etc.
La description qui va suivre en regard des dessins annexés, donnés à titre d'exemples non limitatifs, fera bien comprendre en quoi consiste l'invention et comment elle peut être réalisée.The description which follows with reference to the appended drawings, given by way of nonlimiting examples, will make it clear what the invention consists of and how it can be implemented.
La figure 1 est une vue en perspective d'un premier mode de réalisation d'un complexe souple en feuille conforme à l'invention.Figure 1 is a perspective view of a first embodiment of a flexible sheet complex according to the invention.
La figure 2 est une vue en perspective d'un deuxième mode de réalisation d'un complexe souple en feuille conforme à l'invention.Figure 2 is a perspective view of a second embodiment of a flexible sheet complex according to the invention.
La figure 3 est une vue en perspective d'un premier emballage réalisé à l'aide d'un complexe de l'invention.Figure 3 is a perspective view of a first package made using a complex of the invention.
La figure 4 est une vue en perspective d'un deuxième emballage réalisé à l'aide d'un complexe de l'invention.Figure 4 is a perspective view of a second package produced using a complex of the invention.
La figure 1 montre en perspective un complexe 10 souple en feuille, destiné à être mis en forme autour d'une direction D donnée. Ledit complexe 10 comprend une feuille 11 d'un matériau souple qui peut être du papier, une matière plastique, de l'aluminium, de la mousse ou du carton, éventuellement du carton alimentaire. Sur la feuille 11 est contrecollée une feuille 12 de bois déroulé, extrait d'essences telles que le peuplier, le hêtre, le chêne, etc, le sens des fibres 121 du bois constituant ladite direction D de formage. Le bois déroulé peut, sans inconvénient, être un bois de second choix présentant des noeuds 122 qui en tout état de cause restent en place du fait de leur collage sur la feuille 11 de matériau souple.Figure 1 shows in perspective a
Le complexe ainsi constitué présente une bonne souplesse au formage autour de la direction D, comme l'indiquent les flèches de la figure 1. Par contre, la résistance mécanique aux efforts exercés parallèlement à la direction D est très élevée.The complex thus formed has good flexibility in forming around the direction D, as indicated by the arrows in FIG. 1. On the other hand, the mechanical resistance to the forces exerted parallel to the direction D is very high.
La figure 2 illustre une variante de réalisation dans laquelle une feuille 12,12' de bois déroulé est collée sur chaque face de la feuille 11 de matériau souple, les sens des fibres 121,121' desdites feuilles 12,12' étant disposé parallèlement à la direction D de formage. On conserve ainsi une bonne souplesse mécanique de déformation autour de la direction D, ce qui ne serait pas le cas si les fibres des feuilles de bois déroulé étaient disposées perpendiculairement entre elles.FIG. 2 illustrates an alternative embodiment in which a
Les épaisseurs des différentes feuilles 11,12 et 12' sont choisies telles qu'elles assurent un formage facile tout en garantissant une bonne rigidité mécanique du produit résultant, comme par exemple un emballage.The thicknesses of the
A titre indicatif, les feuilles 12,12' de bois déroulé peuvent avoir une épaisseur variant entre 3/10 et 50/10 mm, tandis que la feuille 11 de matériau souple présente une épaisseur comprise entre 3/10 et 30/10 mm.As an indication, the
Outre des applications particulières à la décoration et au bâtiment, les complexes 10,10' souples en feuille des figures 1 et 2 sont avantageusement utilisées à la fabrication d'emballages dans lesquels ledit complexe est mis en forme autour de la direction D de formage de manière à réaliser un volume tubulaire quelconque.In addition to particular applications in decoration and building, the
La figure 3 montre un premier exemple d'un tel emballage présentant un corps tubulaire 20 cylindrique de révolution formé d'une feuille de complexe 10 ou 10' enroulée sur elle-même autour de la direction D, et collée à l'aide d'une colle à froid ou à chaud. Deux couvercles 21,22 viennent fermer le corps 20 à chacune de ses extrémités. Bien entendu, les portions cylindriques des couvercles 21,22 peuvent également être réalisées à l'aide d'un complexe souple en feuille conforme à l'invention.FIG. 3 shows a first example of such a packaging having a cylindrical
Le deuxième exemple d'emballage représenté sur la figure 4 comporte une paroi consituée par un complexe 10 ou 10' mis en forme autour de la direction D, selon une technique connue des fabricants d'emballages, notamment de boites à fromage, pour réaliser un volume tubulaire cylindrique non de révolution. La paroi 30 est fermé sur un côté par un fond 31.The second example of packaging shown in FIG. 4 comprises a wall formed by a complex 10 or 10 ′ shaped around the direction D, according to a technique known to manufacturers of packaging, in particular cheese boxes, to produce a cylindrical tubular volume not of revolution. The
La section du volume tubulaire de l'emballage de l'invention peut encore avoir d'autres formes, telles que ovale, carrée, rectangulaire, etc.The tubular volume section of the packaging of the invention may also have other shapes, such as oval, square, rectangular, etc.
Les emballages montrés sur les figures 3 et 4 sont formés de façon à laisser apparaître la face bois du complexe à l'extérieure. Naturellement, on pourrait tout aussi bien former ledit complexe afin qu'il rende visible la face portant le matériau souple, carton par exemple.The packages shown in Figures 3 and 4 are formed so as to reveal the wooden side of the complex outside. Naturally, one could just as easily form said complex so that it makes visible the face carrying the flexible material, cardboard for example.
