Abstract

The container forms a rectangular parallelepiped with lengthwise walls (7,8,10) joined together to form a rigid assembly. The walls of the container are of a honeycomb structure, joined together either directly or by connecting elements (11) of cardboard, corrugated cardboard or honeycomb cardboard. At least one of the container's lengthwise walls is joined to an adjacent one by a corner piece of L-section rigid or honeycomb cardboard which is stuck to the adjoining outer surfaces of the contiguous walls. Other walls (7,8) can be made from a single panel of honeycomb cardboard, folded over to form adjacent walls.

Description

La présente invention concerne des conteneurs pour le conditionnement d'objets de diverses dimensions, nécessitant une excellente protection.The present invention relates to containers for packaging objects of various dimensions, requiring excellent protection.

Il est usuel de réaliser des conditionnements de petites dimensions en carton ondulé à une, deux ou trois cannelures, lorsque ces conditionnements ne nécessitent pas une rigidité particulière ou d'autres caractéristiques mécaniques exceptionnelles. De tels conditionnements sont peu coûteux et faciles à réaliser, mais leurs applications sont limitées.It is customary to produce packages of small dimensions in corrugated cardboard with one, two or three grooves, when these packages do not require particular rigidity or other exceptional mechanical characteristics. Such packaging is inexpensive and easy to produce, but their applications are limited.

Lorsque les conteneurs atteignent de grandes dimensions et/ou si leurs caractéristiques mécaniques doivent répondre à des exigences particulières, on a généralement recours à des conteneurs en bois. Le bois résiste à des efforts importants, mais certaines de ses caractéristiques mécaniques, notamment sa résistance à la flexion, sont relativement médiocres, ce qui conduit à l'utiliser en épaisseurs parfois importantes, avec pour conséquence des ensembles lourds et coûteux. Non seulement le coût de fabrication de ces conteneurs est élevé, mais ils entraînent aussi des frais importants d'utilisation, car le coût du transport dépend pour une fraction importante de la masse transportée. En outre, les conteneurs en bois nécessitent pour leur assemblage des clous, agrafes ou autres éléments métalliques, qui compliquent grandement leur recyclage, peuvent s'oxyder et parfois altérer l'aspect des objets conditionnés qui viennent à leur contact.When the containers reach large dimensions and / or if their mechanical characteristics have to meet particular requirements, wooden containers are generally used. Wood withstands significant stresses, but some of its mechanical characteristics, in particular its resistance to bending, are relatively poor, which leads to using it in thicknesses that are sometimes large, resulting in heavy and expensive assemblies. Not only is the cost of manufacturing these containers high, but they also entail significant user costs, since the cost of transport depends for a large fraction of the mass transported. In addition, wooden containers require for their assembly nails, staples or other metallic elements, which greatly complicate their recycling, can oxidize and sometimes alter the appearance of conditioned objects which come into contact with them.

La présente invention vise à remédier à ces inconvénients en proposant de réaliser des conteneurs de grandes dimensions plus légers et moins coûteux que les conteneurs en bois de la technique antérieure, et qui présentent néanmoins des caractéristiques mécaniques au moins égales à celles des conteneurs connus.The present invention aims to remedy these drawbacks by proposing to produce large containers that are lighter and less expensive than wooden containers of the prior art, and which nevertheless have mechanical characteristics at least equal to those of known containers.

Dans ce but, l'invention propose d'utiliser, pour la réalisation de ces conteneurs, le matériau dit carton à nids d'abeilles, c'est-à-dire un matériau comportant deux feuilles de carton ou de carton ondulé entre lesquelles est collée une couche alvéolaire, réalisée en pâte à papier, chaque alvéole de cette couche ayant sensiblement la forme d'un prisme hexagonal, les prismes contigus partagent deux à deux une même face et les arêtes des prismes sont perpendiculaires aux feuilles de carton entre lesquelles ils sont interposés. Ce matériau -auquel on se réfèrera ci-après et dans les revendications annexées par l'expression usuelle "carton en nids d'abeilles"- est connu, en effet, pour sa légèreté et pour ses propriétés mécaniques, et de nombreuses applications en ont déjà été décrites et revendiquées dans la technique, notamment par la Demanderesse dans des brevets antérieurs.To this end, the invention proposes to use, for the production of these containers, the so-called cardboard material to honeycombs, that is to say a material comprising two sheets of cardboard or corrugated cardboard between which a honeycomb layer is bonded, made of paper pulp, each cell of this layer having substantially the shape of a prism hexagonal, the contiguous prisms share two by two the same face and the edges of the prisms are perpendicular to the sheets of cardboard between which they are interposed. This material - which will be referred to below and in the claims appended by the usual expression "honeycomb cardboard" - is known, in fact, for its lightness and for its mechanical properties, and many applications have already described and claimed in the art, in particular by the Applicant in previous patents.

L'invention a par conséquent pour objet un conteneur pour le conditionnement d'objets de diverses dimensions, ce conteneur ayant la forme générale d'un polyèdre, notamment d'un parallélépipède rectangle, comportant des parois longitudinales raccordées entre elles par des arêtes parallèles et des parois d'extrémité, perpendiculaires à ces arêtes, rigidement solidaires les unes des autres, ce conditionnement étant caractérisé en ce que ses différentes parois sont constituées de matériau en nid d'abeille et en ce qu'elles sont assemblées entre elles par collage, directement et/ou par l'intermédiaire d'éléments en carton, en carton ondulé ou en carton en nids d'abeilles.The invention therefore relates to a container for the packaging of objects of various dimensions, this container having the general shape of a polyhedron, in particular of a rectangular parallelepiped, comprising longitudinal walls connected together by parallel edges and end walls, perpendicular to these edges, rigidly secured to one another, this packaging being characterized in that its various walls are made of honeycomb material and in that they are assembled together by bonding, directly and / or by means of cardboard, corrugated cardboard or honeycomb cardboard elements.

Dans une forme de mise en oeuvre de l'invention, l'une au moins des parois longitudinales sera solidaire des deux parois contiguës par des éléments d'assemblage en forme de cornières collés contre les faces externes de la dite paroi longitudinale et des parois contiguës. Cette cornière pourra être en carton, en carton ondulé, ou en carton en nids d'abeilles, suivant les dimensions et les caractéristiques exigées du conteneur.In one embodiment of the invention, at least one of the longitudinal walls will be integral with the two adjoining walls by assembly elements in the form of angles glued against the external faces of said longitudinal wall and adjoining walls . This angle may be made of cardboard, corrugated cardboard, or honeycomb cardboard, depending on the dimensions and characteristics required of the container.

Comme on le verra ci-après, dans la description détaillée de diverses formes de réalisation de l'invention, les autres parois pourront être issues d'une unique plaque de matériau en carton en nids d'abeilles et être attenantes entre elles par pliage au niveau des arêtes longitudinales correspondantes du conteneur, la feuille externe de carton du matériau en nids d'abeilles tournée vers l'intérieur du conteneur ayant été éliminée au niveau de ces arêtes afin de permettre le pliage dudit matériau.As will be seen below, in the detailed description of various embodiments of the invention, the other walls may come from a single plate of honeycomb cardboard material and adjoining each other by folding at the corresponding longitudinal edges of the container, the outer sheet of cardboard honeycomb material facing the inside of the container having been removed level of these edges to allow folding of said material.

Ces autres parois pourront également être constituées de panneaux indépendants en carton en nids d'abeilles et être raccordées entre elles par des éléments en forme de cornière, en carton, en carton ondulé ou en carton en nids d'abeilles, appliqués entre la face externe de ces parois et collés contre celles-ci.These other walls may also consist of independent panels of honeycomb cardboard and be connected together by elements in the form of angle iron, cardboard, corrugated cardboard or cardboard honeycomb, applied between the external face. of these walls and glued against them.

Chaque paroi d'extrémité sera engagée à l'intérieur du fourreau formé par les parois longitudinales et contrecollée contre les faces internes de celles-ci, avec de préférence des cornières collées contre la face externe de la paroi d'extrémité et contre les portions adjacentes des faces internes des parois longitudinales. Alternativement, à la place des cornières, des cales en matériau à nids d'abeilles pourront être collées contre la face externe des parois d'extrémité et contre les portions adjacentes des faces internes des parois longitudinales.Each end wall will be engaged inside the sheath formed by the longitudinal walls and laminated against the internal faces of these, preferably with angles glued against the external face of the end wall and against the adjacent portions. internal faces of the longitudinal walls. Alternatively, instead of the angles, wedges made of honeycomb material may be glued against the external face of the end walls and against the adjacent portions of the internal faces of the longitudinal walls.

Des plots forment supports ou cales latérales en tout matériau approprié et, notamment, en matériau en nids d'abeilles pourront avantageusement être collés contre la face externe d'au moins une paroi longitudinale.Studs form supports or lateral shims in any suitable material and, in particular, in honeycomb material can advantageously be glued against the external face of at least one longitudinal wall.

On notera que le mode de réalisation du conteneur conforme à l'invention, qui exclut l'utilisation de tout organe métallique d'assemblage, permet le recyclage intégral de ce conteneur.It will be noted that the embodiment of the container in accordance with the invention, which excludes the use of any metallic assembly member, allows full recycling of this container.

On se réfèrera d'abord aux figures 1 à 4. Dans cette forme de réalisation, le conteneur a la forme d'un parallélépipède rectangle à section carrée. Il comprend quatre parois longitudinales non attenantes, 1, en carton en nids d'abeilles, et deux parois 2 d'extrémité, également en carton en nids d'abeilles, perpendiculaires aux parois 1.We will first refer to Figures 1 to 4. In this embodiment, the container has the shape of a rectangular parallelepiped with square section. It comprises four non-contiguous longitudinal walls, 1, made of honeycomb cardboard, and two end walls 2, also made of honeycomb cardboard, perpendicular to the walls 1.

Des cornières 3 en carton rigide sont appliquées contre les portions contiguës des faces externes de deux parois parallèles et d'une paroi perpendiculaire et collées contre celles-ci. En revanche, comme on le voit sur la figure 4, l'une des parois longitudinales, 1a, comporte des cornières 3a et 4a préassemblées, de manière à pouvoir venir coiffer le reste du conteneur après remplissage de celui-ci, à la manière d'un couvercle, les cornières 3a venant simplement s'appliquer contre les faces externes des parois contiguës, sans être collées sur celles-ci, de manière à pouvoir positionner et à retirer aisément le couvercle, qui constitue une pièce indépendante. Les cornières 4a assurent le positionnement longitudinal de la paroi 1a.Angle pieces 3 of rigid cardboard are applied against the contiguous portions of the external faces of two parallel walls and of a perpendicular wall and glued against them. On the other hand, as seen in FIG. 4, one of the longitudinal walls, 1 a , includes angles 3 a and 4 a preassembled, so as to be able to cover the rest of the container after filling thereof, in the manner of a cover, the angles 3 a simply coming to be applied against the external faces of the walls contiguous, without being glued to them, so that the cover can easily be positioned and removed, which constitutes an independent part. The angles 4 a ensure the longitudinal positioning of the wall 1 a .

Comme on le voit sur la figure 1, les parois d'extrémité 2 sont engagées à l'intérieur du fourreau formé par les parois 1. Les parties en contact des parois 1 et 2 sont assemblées par collage et des cornières 4 en carton rigide sont appliquées et collées contre la face externe des parois 2 et les portions contiguës de l'extrémité de la face interne des parois 1.As can be seen in FIG. 1, the end walls 2 are engaged inside the sheath formed by the walls 1. The parts in contact with the walls 1 and 2 are assembled by gluing and angles 4 made of rigid cardboard are applied and glued against the external face of the walls 2 and the contiguous portions of the end of the internal face of the walls 1.

On obtient ainsi, de façon simple, un conteneur présentant d'excellentes caractéristiques mécaniques, qui, malgré ses grandes dimensions, est beaucoup plus léger que les conteneurs usuels.There is thus obtained, in a simple manner, a container having excellent mechanical characteristics, which, despite its large dimensions, is much lighter than conventional containers.

Des plots 5, en carton en nids d'abeilles ou en tout autre matériau, pourront être collés contre une ou plusieurs faces latérales des parois longitudinales 1 pour servir d'éléments de support ou de calage.Pads 5, made of honeycomb cardboard or any other material, may be glued against one or more lateral faces of the longitudinal walls 1 to serve as support or wedging elements.

Dans la variante de la figure 5, dont la largeur d'une paroi longitudinale 7 et la hauteur des deux parois longitudinales adjacentes 8 le permettent, la paroi 7 et les parois 8 sont attenantes entre elles de fabrication, c'est-à-dire qu'elles sont issues d'un même panneau en nids d'abeilles découpé à dimensions, qui a été ensuite replié pour permettre de dresser les parois 8 perpendiculairement à la paroi 7. Dans ce but, dans les portions d'angle 9 formant raccordement entre les parois 7 et 8, la plaque externe de carton du carton en nids d'abeilles destinée à former la face interne des parois 7 et 8 a été préalablement éliminée par fraisage sur une largeur suffisante, dans la partie correspondante à la portion d'angle 9, afin de conférer au matériau à nids d'abeilles une souplesse suffisante pour donner par pliage à l'ensemble formé par les parois 7 et 8 la forme en U désirée.In the variant of FIG. 5, the width of a longitudinal wall 7 and the height of the two adjacent longitudinal walls 8 allow it, the wall 7 and the walls 8 are adjacent to each other during manufacture, that is to say that they come from the same honeycomb panel cut to size, which was then folded back to allow the walls 8 to be erected perpendicularly to the wall 7. For this purpose, in the corner portions 9 forming a connection between the walls 7 and 8, the outer plate of cardboard of the honeycomb cardboard intended to form the inner face of the walls 7 and 8 has been previously removed by milling over a sufficient width, in the part corresponding to the portion of angle 9, to give the nesting material bees sufficient flexibility to give by folding the assembly formed by the walls 7 and 8 the desired U-shape.

Il n'est donc plus nécessaire, dans cette forme de réalisation, d'utiliser des cornières externes de raccordement des parois 7 et 8. En revanche, la paroi longitudinale 10 formant couvercle est, comme précédemment, assemblée aux parois 8 par collage des portions en contact mutuel et par collage de deux cornières 11 en carton rigide, appliquées extérieurement contre les parties contiguës des parois 8 et 10.It is therefore no longer necessary, in this embodiment, to use external angles for connecting the walls 7 and 8. On the other hand, the longitudinal wall 10 forming a cover is, as previously, assembled to the walls 8 by bonding the portions in mutual contact and by gluing two angles 11 of rigid cardboard, applied externally against the contiguous parts of the walls 8 and 10.

Les plaques d'extrémité de cette forme de réalisation et leur mode d'assemblage sont analogues à ce qui a été décrit en référence aux figures 1 à 4.The end plates of this embodiment and their method of assembly are analogous to what has been described with reference to FIGS. 1 to 4.

La forme de réalisation illustrée par les figures 6 à 9 est destinée au conditionnement d'objets de très grandes dimensions.The embodiment illustrated in Figures 6 to 9 is intended for the packaging of very large objects.

Dans ce cas, les quatre parois longitudinales 14 sont découpées dans des panneaux en carton en nids d'abeilles et sont assemblées par collage sur les portions contiguës des faces externes des parois adjacentes de cornières 15, également en carton à nids d'abeilles. Afin de permettre le pliage de ces cornières, la portion de la feuille externe de carton rigide du carton en nids d'abeilles destinée à venir en contact avec la face externe des parois 14 a été éliminée dans la partie d'angle des parois 14, afin de permettre le pliage de ces cornières.In this case, the four longitudinal walls 14 are cut from cardboard honeycomb panels and are assembled by gluing on the contiguous portions of the external faces of the adjacent walls of angles 15, also made of honeycomb cardboard. In order to allow the folding of these angles, the portion of the external sheet of rigid cardboard of the honeycomb cardboard intended to come into contact with the external face of the walls 14 has been eliminated in the corner part of the walls 14, to allow the folding of these angles.

Les parois d'extrémité 16 du conteneur sont, comme précédemment, engagées à l'intérieur du fourreau formé par les parois 14, mais ne sont plus rendues solidaires de celles-ci à l'aide de simples cornières en carton rigide. Pour réaliser cet assemblage, on utilise ici des cales 17 en carton en nids d'abeilles, qui sont contrecollées contre les parois 16 et contre les portions adjacentes d'extrémité des faces internes des parois 14.The end walls 16 of the container are, as before, engaged inside the sheath formed by the walls 14, but are no longer made integral with the latter using simple rigid cardboard angles. To carry out this assembly, spacers 17 made of cardboard honeycomb are used here, which are laminated against the walls 16 and against the adjacent end portions of the internal faces of the walls 14.

Comme on le voit sur la figure 9, sur l'une des parois longitudinales, 14a, pourront être fixées deux des cales d'extrémité, 17a, de façon à ce que cette paroi 14a puisse être facilement mise en place à la manière d'un couvercle sur le reste du conteneur préassemblé et empli. Il suffit alors, après les avoir encollées, de rabattre sur la face externe de cette paroi 14a les cornières 15a, 15b, déjà fixées sur deux parois parallèles 14 du conteneur. Les cornières 15a pourraient aussi être précollées sur le couvercle 14a et venir s'appliquer, avec ou sans encollage, contre les faces latérales des parois parallèles 14, lors de la fermeture du conteneur. Les cornières 15a et 15b pourront aussi être collées sur les parois 14 et être rabattues sur la paroi 14a formant couvercle, après mise en place de celle-ci, pour en être rendues solidaires par un feuillard ou un ruban adhésif.As seen in Figure 9, on one of the longitudinal walls 14 a, may be determined in two end wedges, 17 a , so that this wall 14 a can be easily put in place in the manner of a cover over the rest of the pre-assembled and filled container. Just then, after the glued to back on the outer face of this wall 14 has ledges 15 a, 15 b, already fixed to two parallel walls 14 of the container. The angles 15 a could also be pre-glued to the cover 14 a and come to apply, with or without gluing, against the lateral faces of the parallel walls 14, when the container is closed. The angles 15 a and 15 b can also be glued to the walls 14 and be folded down on the wall 14 a forming a cover, after positioning of the latter, so as to be made integral by a strip or an adhesive tape.

Comme précédemment, des plots 18, en carton en nids d'abeilles, peuvent être fixés sur une face externe d'au moins une plaque longitudinale 14. Ces plots 18 permettent le passage d'une fourche d'un chariot de manutention pour faciliter le transport et/ou le gerbage des conteneurs.As before, studs 18, made of honeycomb cardboard, can be fixed on an external face of at least one longitudinal plate 14. These studs 18 allow the passage of a fork of a handling trolley to facilitate the transport and / or stacking of containers.

Les figures 10, 11 et 11A illustrent une autre forme de mise en oeuvre de l'invention.Figures 10, 11 and 11A illustrate another form of implementation of the invention.

Dans cette forme de réalisation, la base 20 du conteneur et deux parois longitudinales 21 perpendiculaires à cette base sont en matériau en nids d'abeilles et comportent à leurs extrémités une partie recourbée, respectivement 20a et 21a, destinées à les rendre solidaires des parois transversales d'extrémité, désignées par la référence générale 22. Les parois 22, perpendiculaires à la base 20 et aux parois longitudinales 21, sont des parois doubles constituées d'un même panneau en un matériau à nids d'abeilles, replié à 180° contre lui-même, avec la ligne de pliage disposée à la partie supérieure du conteneur. Des cornières telles que 23, par exemple en carton rigide, ont une première branche pincée entre les parties contiguës du panneau 22 et collée à celles-ci, et une seconde branche, pincée entre les panneaux 20-21 et les parties recourbées 20a-21a de ces panneaux et collée à ceux-ci.In this embodiment, the base 20 of the container and two longitudinal walls 21 perpendicular to this base are made of honeycomb material and have at their ends a curved part, respectively 20 a and 21 a , intended to make them integral with the transverse end walls, designated by the general reference 22. The walls 22, perpendicular to the base 20 and to the longitudinal walls 21, are double walls made up of the same panel made of a honeycomb material, folded at 180 ° against itself, with the fold line at the top of the container. Angles such as 23, for example made of rigid cardboard, have a first branch pinched between the contiguous parts of the panel 22 and glued to them, and a second branch, pinched between the panels 20-21 and the curved parts 20 a - 21a of these panels and bonded thereto.

Dans cette mise en oeuvre, la partie formant couvercle comprend elle aussi en une partie 24 sensiblement rectangulaire, en un matériau en nids d'abeilles, comportant, suivant deux de ses bords, un double repli 24a et, suivant les deux autres bords, deux cornières préassemblées 25, lui permettent de venir coiffer la partie supérieure du conteneur, c'est-à-dire la partie supérieure des parois 21 et 22.In this implementation, the cover part also comprises a substantially rectangular part 24, made of a honeycomb material, comprising, along two of its edges, a double fold 24 a and, along the other two edges, two pre-assembled angles 25, allow it to come over the upper part of the container, that is to say the upper part of the walls 21 and 22.

Ici encore, des plots 26 sont collés sous la partie du fond 20.Here again, studs 26 are glued under the bottom portion 20.

La figure 12 illustre une variante du conteneur de la figure 10, caractérisée par le repli et le collage sur lui-même du bord supérieur des parois 27. Ce bord replié augmente la rigidité du conteneur, ce qui est intéressant pour les conteneurs de grande longueur, et il protège le chant du nid d'abeilles contre des chocs qui pourraient l'endommager.Figure 12 illustrates a variant of the container of Figure 10, characterized by the folding and gluing on itself of the upper edge of the walls 27. This folded edge increases the rigidity of the container, which is advantageous for containers of great length , and it protects the edge of the honeycomb against shocks that could damage it.

La figure 13 illustre une autre forme de réalisation de l'invention, de hauteur réduite, particulièrement bien adaptée au conditionnement de tôles, par exemple. Elle est constituée d'une base rectangulaire 30 en matériau en nid d'abeilles, comportant suivant tous ses bords un double repli 30a, de façon à coiffer des cales 31 qui peuvent aussi être réalisées en matériau en nid d'abeilles. Les faces inférieures et supérieures des cales 31 sont collées respectivement à la base 30 et aux replis 30a. Des cornières 32, collées contre les parties supérieures des replis 30a et le chant interne des cales 31 et des replis 30a, rigidifient l'ensemble tout en protégeant les chants en nid d'abeilles des cales 31 et des replis 30a.FIG. 13 illustrates another embodiment of the invention, of reduced height, particularly well suited to the packaging of sheets, for example. It consists of a rectangular base 30 made of honeycomb material, comprising along all of its edges a double fold 30 a , so as to cover wedges 31 which can also be made of honeycomb material. The lower and upper faces of the wedges 31 are glued respectively to the base 30 and to the folds 30 a . Corner pieces 32, glued against the upper parts of the folds 30 a and the internal edge of the shims 31 and the folds 30 a , stiffen the assembly while protecting the honeycomb edges of the shims 31 and the folds 30 a .

Le couvercle 33 est une simple plaque en matériau en nid d'abeilles, de dimensions permettant une insertion dans le logement délimité par les quatre cornières 32. Si nécessaire, des cales d'épaisseur adaptée 34 sont posées sur le couvercle 33, afin d'éviter après sanglage tout déplacement vertical des tôles. Les évidements 30b permettent non seulement le pliage des bords 30a, mais aussi le contrôle et la prise des objets conditionnés.The cover 33 is a simple plate made of honeycomb material, of dimensions allowing insertion into the housing delimited by the four angles 32. If necessary, shims of suitable thickness 34 are placed on the cover 33, in order to after strapping, avoid any vertical displacement of the sheets. The recesses 30 b allow not only the folding of the edges 30 a , but also the control and the taking of conditioned objects.

Ici encore, des plots 35 sont collés sous la base 30.Here again, pads 35 are glued under the base 30.
