Abstract

The invention relates to a variant of the strengthening structure according to the main patent. In this variant, the inside face of the stiffening elements 5 of the semi-rigid sheet 4 are joined to at least one strengthening component 6 of complementary profile made of a sufficiently stiff material to render said semi-rigid sheet self-supporting.

Description

Nouvelle structure de renfort pour conteneur en un matériau semi-rigide et conteneur équipé de cette structure. New reinforcement structure for container in semi-rigid material and container equipped with this structure.

La présente addition concerne des variantes de réalisation de la structure de renfort pour conteneur en un matériau semi-rigide faisant l'objet du brevet principal. The present addition relates to alternative embodiments of the reinforcement structure for a container made of a semi-rigid material which is the subject of the main patent.

On rappelle que cette structure comporte, selon la revendication 1 du brevet principal, au moins une plaque plane en un matériau semi-rigide tel que le carton ondulé destinée à être appliquée contre la face interne d'une paroi verticale du conteneur, cette plaque plane étant doublée, sur sa face destinée à être tournée vers l'intérieur du conteneur, d'une feuille également en un matériau semi-rigide tel que le carton ondulé, qui est rigidement solidaire de ladite plaque et sur laquelle des lignes de pliage destinées à être placées perpendiculairement aux arêtes verticales du conteneur définissent au moins un et, de préférence, plusieurs éléments raidisseurs à section transversale triangulaire, rectangulaire ou autre, faisant saillie vers l'intérieur du conteneur. Recall that this structure comprises, according to claim 1 of the main patent, at least one flat plate made of a semi-rigid material such as corrugated cardboard intended to be applied against the internal face of a vertical wall of the container, this flat plate being lined, on its face intended to be turned towards the interior of the container, with a sheet also of a semi-rigid material such as corrugated cardboard, which is rigidly secured to said plate and on which fold lines intended for be placed perpendicular to the vertical edges of the container define at least one and, preferably, several stiffening elements of triangular, rectangular or other cross section, projecting towards the interior of the container.

Ces structures sont destinées à être appliquées contre la face interne de chacune des parois du conteneur et ont des dimensions correspondant sensiblement à celles de ces parois, afin de les recouvrir intégralement. These structures are intended to be applied against the internal face of each of the walls of the container and have dimensions corresponding substantially to those of these walls, in order to completely cover them.

La plaque et la feuille en un matériau semi-rigide sont rendues solidaires l'une de l'autre par collage ou agrafage et, du fait de leur double épaisseur et de la présence des éléments raidisseurs qui forment poutres, les structures ainsi réalisées renforcent très efficacement les parois du conteneur et en suppriment ou limitent les risques de déformation. En particulier, le ou les éléments raidisseurs disposés horizontalement s'opposent fermement au bombage des parois. The plate and the sheet of semi-rigid material are made integral with one another by gluing or stapling and, because of their double thickness and the presence of the stiffening elements which form beams, the structures thus produced very reinforce the walls of the container effectively and eliminate or limit the risks of deformation. In particular, the stiffening element or elements arranged horizontally firmly oppose the bending of the walls.

De préférence, ces éléments raidisseurs sont rigidifiés intérieurement par des traverses de bois ou similaires, de section correspondante,qui y sont engagées. Preferably, these stiffening elements are internally stiffened by wooden sleepers or the like, of corresponding section, which are engaged therein.

En poursuivant ses travaux sur ce type de structures, la Demanderesse a conçu diverses formes de réalisation dans lesquelles les traverses de bois renforçant les éléments raidisseurs peuvent etre supprimées, de mEme que la plaque plane formant support. While continuing its work on this type of structure, the Applicant has designed various embodiments in which the wooden sleepers reinforcing the stiffening elements can be eliminated, as is the flat plate forming a support.

n effet, il est possible de coller sur la face interne des éléments raidisseurs, c'est-à-dire sur la face tournée vers la paroi associée, un élément de renfort de profil complémentaire en un matériau rigide ou semi-rigide, qui interdit à la feuille de matière semi-rigide de se déformer par pivotement autour des lignes de pliage. De cette manière, la feuille semi-rigide forme à elle seule une structure auto-portante, qu'il n'est pas nécessaire de doubler par une plaque support sur laquelle elle est fixée. n effect, it is possible to bond on the internal face of the stiffening elements, that is to say on the face facing the associated wall, a reinforcing element of complementary profile made of a rigid or semi-rigid material, which prohibits the sheet of semi-rigid material to deform by pivoting around the fold lines. In this way, the semi-rigid sheet alone forms a self-supporting structure, which it is not necessary to double with a support plate on which it is fixed.

3ien entendu, l'usage d'une telle plaque n'est nullement exclu si l'on désire accroître encore la rigidité de la structure de renfort. Of course, the use of such a plate is in no way excluded if it is desired to further increase the rigidity of the reinforcing structure.

Un premier objet de l'invention est donc constitué par une structure de renfort conforme au brevet principal, caractérisée en ce que les éléments raidisseurs de la feuille semi-rigide sont solidaires par leur face interne d'au moins un élément de renfort de profil complémentaire, en un matériau d'une rigidité suffisante pour rendre ladite feuille semi-rigide auto-portante. A first object of the invention therefore consists of a reinforcing structure in accordance with the main patent, characterized in that the stiffening elements of the semi-rigid sheet are integral by their internal face with at least one reinforcing element with a complementary profile. , in a material of sufficient rigidity to make said semi-rigid sheet self-supporting.

Dans une forme de mise en oeuvre préférée de cette forme de réalisation, la structure de renfort sera constituée uniquement de ladits feuille semi-rigide rendue autoportante, à l'exclusion de toute plaque support en un matériau semi-rigide0
Les éléments de renfort des raidisseurs pourront être en bois, en matière plastique, ou en un matériau constitué de plusieurs couches de papier, de carton, de carton ondulé ou tout autre matériau stratifiés
La structure de renfort ainsi réalisée sera à l'évi- dence beaucoup moins coûteuse que se était nécessaire d'utiliser des poutres en bois et/ou une plaque support en carton.
In a preferred embodiment of this embodiment, the reinforcing structure will consist only of said semi-rigid sheet made self-supporting, to the exclusion of any support plate made of a semi-rigid material.
The reinforcing elements of the stiffeners may be made of wood, plastic, or a material consisting of several layers of paper, cardboard, corrugated cardboard or any other laminated material.
The reinforcement structure thus produced will obviously be much less expensive than it was necessary to use wooden beams and / or a cardboard support plate.

Toujours dans le but de rendre auto-portante la feuille en un matériau semi-rigide dans laquelle sont formés les éléments raidisseurs, on pourra avantageusement utiliser un carton ondulé thermoformé, c'est-à-dire un carton dont les cannelures et les eouvertures ont été enduites d'une résine thermofusible ou thermoplastique, qui, en durcissant, les rend solidaires les unes des autres tout en conférant au carton ondulé une excellente rigidité ou, de préférence, un carton constitué de papiers spéciau2S comprenant un mélange de fibres cellulosiques et de fibres plastiques, ces dernières étant ramollies par la chaleur au cours du thermoformage et conservant la forme désirée après refroidissement. Still with the aim of making the sheet of semi-rigid material self-supporting in which the stiffening elements are formed, it is advantageous to use thermoformed corrugated cardboard, that is to say a cardboard whose grooves and openings have have been coated with a hot-melt or thermoplastic resin, which, by hardening, makes them integral with each other while giving the corrugated board excellent rigidity or, preferably, a board made of special papers comprising a mixture of cellulose fibers and plastic fibers, the latter being softened by heat during thermoforming and retaining the desired shape after cooling.

Un second objet de l'invention est donc constitué par une structure de renfort conforme au brevet principal, caractérisée en ce que la feuille en un matériau semi-rigide dans laquelle sont formés les éléments raidisseurs est constituée d'un carton ondulé thermoformé. A second object of the invention therefore consists of a reinforcing structure in accordance with the main patent, characterized in that the sheet of semi-rigid material in which the stiffening elements are formed consists of thermoformed corrugated cardboard.

Ici encore, dans une forme de mise en oeuvre préférée de cette forme de réalisation, la structure de renfort sera constituée exclusivement de cette feuille en carton ondulé thermoformé, puisque celle-ci présentera une rigidité suffisante pour etre auto-portante e
Une telle structure sera donc elle aussi facile à réaliser et dtun coût peu élevé.
Here again, in a preferred embodiment of this embodiment, the reinforcing structure will consist exclusively of this sheet of thermoformed corrugated cardboard, since it will have sufficient rigidity to be self-supporting and
Such a structure will therefore also be easy to produce and of low cost.

Les dessins schématiques annexée illustrent les deux formes de réalisation de la structure conforme à la présente addition. Sur ces dessins
La figure 9 représente une caisse, à laplomb de laquelle est disposée une structure de renfort en carton ondulé thermoformé ;
La figure 2 est une vue de détail dlune structure de renfort dans laquelle les éléments raidisseurs sont renforcés intérieurement par un élément rigide de même profil.
The attached schematic drawings illustrate the two embodiments of the structure according to this addition. On these drawings
FIG. 9 represents a box, plumb with which is placed a reinforcing structure of thermoformed corrugated cardboard;
Figure 2 is a detail view of a reinforcing structure in which the stiffening elements are internally reinforced by a rigid element of the same profile.

La caisse 1 de la figure 1 est du même type que celle décrite au brevet principal. La structure de renfort est constituée uniquement par une feuille 2 en carton ondulé, dont les cannelures et les couvertures sont assemblées à l'aide d'une colle thermofusible, qui confère à l'ensemble une rigidité proche de celle du bois. The body 1 of Figure 1 is of the same type as that described in the main patent. The reinforcing structure consists solely of a sheet 2 of corrugated cardboard, the grooves and the covers of which are assembled using a hot-melt adhesive, which gives the assembly a rigidity close to that of wood.

Dans ces conditions, la feuille 2 est auto-portante et il n'est pas nécessaire de la rendre solidaire dune plaque support. Les éléments raidisseurs 3 de la feuille 2 n'ont pas, non plus, besoin d'être renforcés intérieurement, comme décrit au brevet principal, par des poutres en bois de section correspondante (triangulaire, dans le cas présent). Under these conditions, the sheet 2 is self-supporting and it is not necessary to make it integral with a support plate. The stiffening elements 3 of the sheet 2 do not need to be reinforced internally, as described in the main patent, by wooden beams of corresponding section (triangular, in this case).

La feuille 4 représentée sur la figure 2 est elle aussi en carton ondulé, mais les éléments raidisseurs 5, à section triangulaire, qu'elle comporte sont renforcés intérieurement par un dièdre 6 en matière plastique, en bois ou en stratifié, collé contre la face correspondante de l'élément raidisseur. The sheet 4 shown in FIG. 2 is also made of corrugated cardboard, but the stiffening elements 5, of triangular section, which it comprises are internally reinforced by a dihedral 6 made of plastic, wood or laminate, glued against the face. corresponding to the stiffening element.

Dans ce cas également, la feuille 4 est auto portante et suffisamment rigide pour qu'il ne soit pas nécessaire de la doubler d'une plaque support et de renforcer int6- rieurement les éléments raidisseurs 5 par des traverses.  In this case also, the sheet 4 is self-supporting and sufficiently rigid so that it is not necessary to double it with a support plate and to reinforce internally the stiffening elements 5 by crosspieces.
