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 the packaging of 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 usual to carry out packaging of small dimensions in one, two or three corrugated cardboard grooves, when these packages do not require no particular stiffness or other characteristics exceptional mechanical properties. Such packages are inexpensive and easy to make, 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 entraínent 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 must meet specific requirements, we have usually use wooden containers. Wood withstands significant efforts, but some of its mechanical characteristics, in particular its resistance to bending, are relatively poor, which leads to use it in thicknesses sometimes important, with for consequence of the heavy and expensive assemblies. Not only the cost of manufacturing these containers is high, but they also entail significant user fees, because the cost of transport depends for a fraction significant 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 to their contact.

On connaít par DE-B-1 141 221 un conteneur conforme à la partie préambule de la revendication 1.DE-B-1 141 221 discloses a conforming container in the preamble part of claim 1.

On connaít par ailleurs par US-A-5 040 696 un conteneur dans lequel l'une au moins des parois longitudinales est solidaire d'au moins une paroi adjacente à l'aide d'éléments en forme de cornières, en carton rigide, collées sur les portions contiguës des faces externes de ladite paroi longitudinale et des parois adjacentes.We also know from US-A-5,040,696 a container in which at least one of the walls longitudinal is secured to at least one wall adjacent using angle-shaped elements, rigid cardboard, glued to the adjoining portions of external faces of said longitudinal wall and walls adjacent.

La présente invention vise à 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 make containers large dimensions lighter and less expensive than wooden containers of the prior art, and which nevertheless have mechanical characteristics less equal to those of known containers.

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.The invention proposes to use, for the realization of these containers, the material known as nest box of bees, i.e. a material comprising two sheets of cardboard or corrugated cardboard between which a honeycomb layer is glued, made of paper, each cell of this layer having substantially the shape of a hexagonal prism, the adjoining prisms share the same side in pairs and the edges of prisms are perpendicular to the sheets of cardboard between which they are interposed. This material - which we will refer below and in the claims appended by the usual expression "honeycomb cardboard" - is known, indeed, for its lightness and for its properties mechanical, and many applications have already been described and claimed in the art, in particular by the Applicant in prior patents.

L'invention a pour objet un conteneur conforme à la revendication 1.The subject of the invention is a container in accordance with claim 1.

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.Note that the embodiment of the container according to the invention, which excludes the use of any metal assembly member, allows recycling full of this container.

Les dessins annexés, qui n'ont pas de caractère limitatif illustrent une forme de réalisation de l'invention. Sur ces dessins :

  • La figure 1 est une vue en perspective éclatée d'un conteneur conforme à l'invention ;
  • Les figures 2 et 2A sont des vues de détail en coupe de deux réalisations du conteneur de la figure 1 ;
  • La figure 3 est une vues en perspective éclatée d'une forme modifiée de réalisation du conteneur conforme à l'invention.
    • The accompanying drawings, which are not limiting, illustrate an embodiment of the invention. In these drawings:
  • Figure 1 is an exploded perspective view of a container according to the invention;
  • Figures 2 and 2A are detailed sectional views of two embodiments of the container of Figure 1;
  • Figure 3 is an exploded perspective view of a modified embodiment of the container according to the invention.

    • On se réfèrera d'abord aux figures 1 à 2A. We will first refer to Figures 1 to 2A.

    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.The base 20 of the container and two longitudinal walls 21 perpendicular to this base are made of honeycomb material and comprise 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 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 part from the bottom 20.

    La figure 3 illustre une variante du conteneur de la figure 1, 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 3 illustrates a variant of the container Figure 1, characterized by the folding and gluing on itself from the upper edge of the walls 27. This folded edge increases the rigidity of the container, which is interesting for long containers, and it protects the song of the honeycomb against shocks that could damage it.
