Description

La présente invention concerne un flan en carton, carton ondulé ou matière analogue semi-rigide, destiné à la mise en forme d'une ceinture latérale de préférence de section polygonale d'un container, ainsi que le container pour le conditionnement d'objets, réalisé notamment à partir de l'empilage des ceintures latérales obtenues.The present invention relates to a blank made of cardboard, corrugated cardboard or similar semi-rigid material, intended for shaping a lateral belt preferably of polygonal section of a container, as well as the container for the packaging of objects, made in particular from the stack of lateral belts obtained.

Pour assurer le transport d'objets en général, tels que des produits alimentaires, des pièces, etc..., qu'ils soient déjà conditionnés ou en vrac, d'un site de stockage et/ou de fabrication à un site de distribution ou d'un atelier à un autre, on utilise des containers ou caisses de grand volume susceptibles de contenir lesdits objets en question. Aussi, ces containers doivent-ils être robustes, réutilisables pour permettre un grand nombre de rotations entre les différents sites et/ou ateliers, et également mis à plat lorsqu'ils sont vides pour occuper un volume minimal.To transport objects in general, such as food products, parts, etc., whether already packaged or in bulk, from a storage and / or manufacturing site to a distribution site or from one workshop to another, containers or crates of large volume that may contain the said objects are used. Also, these containers must be robust, reusable to allow a large number of rotations between the different sites and / or workshops, and also flat when they are empty to occupy a minimum volume.

De plus, la mise en palette est une condition importante des emballages de ce type en raison du poids souvent élevé des objets chargés, ce qui permet de faciliter leur déplacement. En outre, le transport de containers partiellement remplis est coûteux et à éviter, de sorte qu'il est intéressant d'adapter au mieux leur volume aux charges à transporter.In addition, the palletizing is an important condition of packaging of this type because of the often high weight of the loaded objects, which facilitates their movement. In addition, the transport of partially filled containers is expensive and avoid, so it is interesting to better adapt their volume to the loads to be transported.

Un container remplissant ces différents aspects est notamment proposé dans le document FR 2 921 350 de la Demanderesse et comprend pour cela un fond et au moins une ceinture latérale en carton, carton ondulé ou autre matière semi-rigide, composée de deux éléments de ceinture. Chacun d'eux est obtenu à partir d'un flan du type comportant une suite de panneaux alignés liés les uns aux autres par des lignes de pliage parallèles pour former, après pliage autour desdites lignes, l'élément de ceinture concerné.A container fulfilling these different aspects is notably proposed in the document FR 2 921 350 of the Applicant and comprises for this purpose a bottom and at least one lateral belt of cardboard, corrugated cardboard or other semi-rigid material, composed of two belt elements. Each of them is obtained from a blank of the type comprising a series of aligned panels connected to each other by parallel fold lines to form, after folding around said lines, the belt member concerned.

Dans cette réalisation, les panneaux de chaque flan sont au nombre de quatre, de sorte que l'élément de ceinture obtenu a une section transversale rectangulaire avec les quatre panneaux opposés parallèlement deux à deux.In this embodiment, the panels of each blank are four in number, so that the resulting belt element has a rectangular cross section with the four panels opposite parallel two by two.

Les deux flans sont disposés l'un sur l'autre et de manière décalée en hauteur l'un par rapport à l'autre de manière à constituer, après pliage, une ceinture latérale ayant un élément de ceinture interne et un élément de ceinture externe, avec des bords inférieur et supérieur desdits éléments faisant saillie en opposition de ladite ceinture obtenue.The two blanks are arranged one above the other and offset in height relative to one another so as to constitute, after folding, a side belt having an inner belt member and an outer waist member. , with lower and upper edges of said elements protruding in opposition to said belt obtained.

On comprend donc que la réalisation du container consiste en l'assemblage par emboîtement de plusieurs ceintures, le bord inférieur en saillie de l'élément interne d'une première ceinture venant s'emboîter dans le bord supérieur en saillie de l'élément externe d'une deuxième ceinture et ainsi de suite. De la sorte, on constitue un container modulable en hauteur par la superposition des ceintures, avec des panneaux latéraux doublés en épaisseur par les deux éléments de ceinture assemblés, ce qui confère au container une rigidité importante, avec une facilité de montage appréciable par l'emboîtement des bords périphériques concernés. De plus, on peut ainsi ajuster le volume du container par le nombre de ceintures à empiler et donc adapter celui-ci aux objets à transporter.It is therefore understood that the embodiment of the container consists of the assembly by interlocking of several belts, the lower edge protruding from the inner element of a first belt coming to fit into the upper edge protruding from the external element of a second belt and so on. In this way, a modular container height is formed by the superposition of the belts, with side panels lined in thickness by the two assembled belt elements, which gives the container a high rigidity, with ease of assembly appreciable by the nesting of the peripheral edges concerned. In addition, it is possible to adjust the volume of the container by the number of belts to stack and thus adapt it to the objects to be transported.

Bien que donnant des résultats satisfaisants, les containers obtenus à partir de ces ceintures à deux éléments sont malgré tout onéreux et grands consommateurs de matière puisqu'ils sont finalement composés pour chaque ceinture de deux éléments de ceinture associés obtenus à partir de deux flans sensiblement identiques, superposés.Although giving satisfactory results, the containers obtained from these belts with two elements are nevertheless expensive and large consumers of material since they are finally composed for each belt of two associated belt elements obtained from two substantially identical blanks , superimposed.

La présente invention a pour but de remédier à ces inconvénients et concerne notamment un flan pour la réalisation d'une ceinture latérale d'un container, dont la conception assure une économie de matière significative tout en conservant une rigidité suffisante pour ladite ceinture obtenue.The present invention aims to remedy these drawbacks and concerns in particular a blank for the production of a side belt of a container, whose design provides a significant material saving while maintaining sufficient rigidity for said belt obtained.

A cet effet, le flan en carton, carton ondulé ou matière analogue semi-rigide, pour la réalisation d'une ceinture latérale de section polygonale d'un container, du type comportant une suite de panneaux alignés liés les uns aux autres par des premières lignes de pliage parallèles pour former, après pliage autour desdites premières lignes, ladite ceinture latérale, est remarquable, selon l'invention, en ce qu'il comprend, de plus, sur un premier côté de ladite suite de panneaux :

  • des évidements ménagés dans les angles de chacun desdits panneaux, et
  • des rabats latéraux de renfort prolongeant ladite suite de panneaux à évidements autour de deuxièmes lignes de pliage perpendiculaires auxdites premières lignes, et s'étendant sensiblement tout du long de chaque panneau en passant sur lesdits évidements ; et
sur le second côté de ladite suite de panneaux :
  • des tenons latéraux faisant saillie des angles desdits panneaux et situés sensiblement en correspondance desdits évidements, lesdits tenons latéraux ayant une forme complémentaire de celle desdits évidements.
For this purpose, the blank made of cardboard, corrugated cardboard or semi-rigid analogous material, for the production of a lateral belt of polygonal section of a container, of the type comprising a series of aligned panels connected to each other by first parallel folding lines for forming, after folding around said first lines, said lateral belt, is remarkable, according to the invention, in that it further comprises, on a first side of said series of panels:
  • recesses in the corners of each of said panels, and
  • lateral reinforcing flaps extending said series of recess panels about second fold lines perpendicular to said first lines, and extending substantially along each panel passing over said recesses; and
on the second side of the said series of panels:
  • lateral tenons projecting from the corners of said panels and located substantially in correspondence with said recesses, said lateral tenons having a shape complementary to that of said recesses.

Ainsi, grâce à l'invention, un seul et même flan sert à la réalisation de la ceinture latérale entraînant une économie de matière et de coût importante, tout en conservant les propriétés avantageuses de la ceinture double antérieure.Thus, thanks to the invention, one and the same blank is used for the realization of the side belt resulting in saving material and cost, while retaining the advantageous properties of the previous double belt.

En effet, le principe d'emboîtement des ceintures est conservé et obtenu par l'engagement des tenons situés dans les coins d'une première ceinture formée dans les évidements correspondants d'une seconde ceinture formée, ce qui assure un calage optimal de celles-ci après empilage. La rigidité et l'assise des ceintures l'une sur l'autre sont assurées par les rabats de renfort repliés contre les panneaux sur tout leur pourtour en renforçant notamment les endroits où ils sont évidés ce qui permet par ailleurs de guider et maintenir les tenons, et en doublant ainsi l'épaisseur du bord supérieur de la ceinture portante au niveau de la coopération entre les panneaux correspondants des ceintures. Ainsi, lesdits rabats de renfort du flan, une fois repliés, constituent l'élément de ceinture interne précédent. Par ailleurs, une fois utilisée, la ceinture peut être mise à plat.Indeed, the principle of interlocking the belts is preserved and obtained by the engagement of the tenons located in the corners of a first belt formed in the corresponding recesses of a second belt formed, which ensures an optimal wedging of those here after stacking. The rigidity and the seat of the belts one on the other are provided by the reinforcing flaps folded against the panels all around their circumference, particularly reinforcing the places where they are hollowed out which also allows to guide and hold the tenons. , and thus doubling the thickness of the upper edge of the carrying belt at the level of cooperation between the corresponding panels of the belts. Thus, said blank reinforcement flaps, once folded, constitute the previous internal belt element. Moreover, once used, the belt can be laid flat.

Avantageusement, la hauteur desdits rabats latéraux est au moins égale à la profondeur desdits évidements, de manière à les obturer totalement par le repliement desdits rabats latéraux contre lesdits panneaux respectifs lors de la mise en forme de ladite ceinture. Le pourtour de celle-ci est ainsi renforcé par les rabats sur une hauteur suffisante.Advantageously, the height of said side flaps is at least equal to the depth of said recesses, so as to completely close them by the folding of said side flaps against said respective panels during the shaping of said belt. The periphery thereof is thus reinforced by the flaps on a sufficient height.

De préférence, lesdits évidements sont de forme identique et agencés de façon symétrique l'un par rapport à l'autre, aux angles de chaque panneau dudit côté correspondant de la suite, et lesdits tenons latéraux sont de forme identique, la hauteur de ceux-ci étant sensiblement égale à la profondeur desdits évidements.Preferably, said recesses are of identical shape and arranged symmetrically with respect to each other, at the corners of each panel of said corresponding side of the suite, and said lateral tenons are of identical shape, the height of these ci being substantially equal to the depth of said recesses.

Dans un mode particulier de réalisation, ledit flan présente, sur le second côté de ladite suite de panneaux, des rabats latéraux reliés auxdits panneaux par des troisièmes lignes de pliage parallèles aux deuxièmes et s'étendant respectivement entre lesdits tenons saillants correspondants issus desdits panneaux. Ces rabats latéraux vont servir de surfaces d'appui pour la ceinture formée destinée à venir au contact d'une palette.In a particular embodiment, said blank has, on the second side of said series of panels, side flaps connected to said panels by third fold lines parallel to the second and respectively extending between said corresponding projecting lugs from said panels. These side flaps will serve as bearing surfaces for the formed belt intended to come into contact with a pallet.

Par ailleurs, dudit premier côté de ladite suite, sont prévues des languettes latérales prolongeant au moins les panneaux destinés à se trouver en parallèle après la mise en forme de ladite ceinture, au-delà desdites deuxièmes lignes de pliage en direction desdits rabats latéraux correspondants, une ligne de découpe séparant lesdites languettes desdits rabats latéraux. Ainsi, ces languettes vont participer, en plus des combinaisons tenons-évidements, au maintien des ceintures latérales empilées.Moreover, said first side of said sequence is provided with lateral tabs extending at least the panels intended to be in parallel after the shaping of said belt, beyond said second fold lines in the direction of said corresponding lateral flaps, a cutting line separating said tabs from said side flaps. Thus, these tabs will participate, in addition to tenon-recess combinations, the maintenance of stacked side belts.

De plus, le flan comporte un tenon transversal de fermeture de ladite suite de panneaux, ledit tenon transversal étant relié à l'un des panneaux d'extrémité de ladite suite autour d'une ligne de pliage parallèle aux premières lignes de pliage desdits panneaux.In addition, the blank comprises a transverse pin for closing said series of panels, said transverse pin being connected to one of the end panels of said sequence around a fold line parallel to the first fold lines of said panels.

L'invention concerne également une ceinture latérale de container à section polygonale, du type comportant une suite formée de panneaux pliés autour de premières lignes de pliage parallèle, verticales.The invention also relates to a polygonal section container side belt, of the type comprising a series of panels folded around first vertical parallel folding lines.

Avantageusement, elle est obtenue à partir dudit flan tel que défini ci-dessus.Advantageously, it is obtained from said blank as defined above.

L'invention concerne aussi un container pour le conditionnement d'objets, du type comportant un fond et au moins deux ceintures latérales réalisées en carton ou matière analogue semi-rigide et aptes à être emboîtées l'une dans l'autre au fur et à mesure du remplissage dudit container, chaque ceinture latérale comprenant une suite fermée à section polygonale, de panneaux pliés autour de premières lignes de pliage parallèles, verticales.The invention also relates to a container for the packaging of objects, of the type comprising a bottom and at least two side belts made of cardboard or similar semi-rigid material and able to be fitted one inside the other as and when measuring the filling of said container, each lateral belt comprising a closed series with a polygonal section, panels folded around first vertical parallel folding lines.

Selon l'invention, le container est remarquable en ce que sont prévus, du côté périphérique supérieur de chaque ceinture latérale :

  • des évidements ménagés dans les angles de chaque panneau, de sorte que deux panneaux consécutifs de ladite suite ont des évidements attenants coudés autour de ladite première ligne de pliage correspondante, et
  • des rabats latéraux de renfort prolongeant lesdits panneaux à évidements autour de deuxièmes lignes et repliés contre lesdits panneaux sur le pourtour interne de ladite suite de panneaux en passant derrière lesdits évidements, et du côté périphérique inférieur,
  • des tenons latéraux faisant saillie des angles de chaque panneau et situés sensiblement en correspondance desdits évidements, lesdits tenons latéraux ayant une forme complémentaire de celle desdits évidements, de manière que lesdits tenons d'une ceinture s'engagent dans lesdits évidements de l'autre ceinture.
According to the invention, the container is remarkable in that are provided on the upper peripheral side of each lateral belt:
  • recesses formed in the corners of each panel, such that two consecutive panels of said series have adjoining recesses bent around said corresponding first fold line, and
  • lateral reinforcing flaps extending said recessed panels around second lines and folded against said panels on the inner periphery of said series of panels passing behind said recesses, and on the lower peripheral side,
  • lateral tenons protruding from the corners of each panel and situated substantially in correspondence with said recesses, said lateral tenons having a shape complementary to that of said recesses, so that said tenons of one belt engage in said recesses of the other belt; .

Ainsi, les ceintures empilées progressivement lors du chargement des objets sont correctement calées par les assemblages tenons-évidements prévus aux coins des panneaux adjacents, et chacune des ceintures repose sur les panneaux renforcés par les rabats repliés d'une ceinture inférieure, ce qui assure la bonne tenue du container ainsi monté. Et notamment, au niveau des évidements qui sont doublés par la surépaisseur des rabats de renfort.Thus, the belts stacked progressively during the loading of the objects are properly wedged by the assemblies tenons-recesses provided at the corners of the adjacent panels, and each of the belts rests on the panels reinforced by the folded flaps of a lower belt, which ensures the good holding of the container thus mounted. And in particular, at the level of the recesses which are doubled by the extra thickness of the reinforcement flaps.

De préférence, la hauteur desdits rabats latéraux est au moins égale à la profondeur desdits évidements de manière que ceux-ci soient complètement obturés par lesdits rabats latéraux repliés.Preferably, the height of said side flaps is at least equal to the depth of said recesses so that they are completely closed by said folded side flaps.

Par exemple, lesdits évidements sont de forme identique à profil rectangulaire ou analogue et sont agencés symétriquement l'un par rapport à l'autre aux angles de chaque panneau ; et lesdits tenons saillants sont de forme identique, la hauteur desdits tenons saillants étant sensiblement égale à la profondeur desdits évidements.For example, said recesses are of identical shape with rectangular profile or the like and are arranged symmetrically with respect to the other at the corners of each panel; and said projecting lugs are of identical shape, the height of said projecting lugs being substantially equal to the depth of said recesses.

En particulier, le container présente, du côté périphérique inférieur de ladite ceinture latérale inférieure, des rabats latéraux repliés perpendiculairement vers l'intérieur de ladite ceinture autour de troisièmes lignes de pliage parallèles auxdites deuxièmes, et situés entre lesdits tenons saillants desdits panneaux. Ces rabats servent de surfaces d'appui à la première ceinture posée sur une palette ou autre agencement formant, par exemple, le fond du container.In particular, the container has, on the lower peripheral side of said lower lateral belt, side flaps folded perpendicularly towards the inside of said belt around third fold lines parallel to said second, and located between said projecting lugs of said panels. These flaps serve as bearing surfaces for the first belt placed on a pallet or other arrangement forming, for example, the bottom of the container.

Comme le montre la figure 1, le flan 1 réalisé de préférence en carton ou en carton ondulé comporte, dans cet exemple, une suite de quatre panneaux 2, 3, 4, 5 deux à deux identiques et qui sont reliés par des premières lignes de pliage parallèles 6 verticales. Le long du bord libre du panneau extérieur 2 (celui de gauche sur la figure 1) est prévu un tenon transversal 7 articulé à ce panneau autour d'une ligne de pliage identique 6 et qui sert, de façon usuelle, à la fermeture de la ceinture par collage ou un autre moyen de fixation approprié sur le bord libre de l'autre panneau extrême 5.As shown in figure 1 , the blank 1 preferably made of cardboard or corrugated cardboard comprises, in this example, a sequence of four panels 2, 3, 4, 5 two by two identical and which are connected by first vertical parallel fold lines 6. Along the free edge of the outer panel 2 (the one on the left on the figure 1 ) is provided a transverse pin 7 hinged to this panel around an identical fold line 6 and which serves, in the usual way, to fasten the belt by gluing or other suitable fastening means on the free edge of the other end panel 5.

On comprend donc que, avec quatre panneaux alignés, la ceinture latérale obtenue 8 (figure 3) a une section transversale polygonale, dans ce cas rectangulaire, avec deux grands panneaux 3, 5 et deux petits panneaux 2, 4. Bien évidemment, le flan 1 pourrait comporter un nombre différent de panneaux, mais quatre est la configuration la plus souhaitée pour l'obtention d'une ceinture latérale 8 et, par voie de conséquence, d'un container parallélépipédique 9 tel que celui illustré en figure 3 et constitué d'un empilage de quatre ceintures latérales emboîtées, superposées.It is therefore understood that, with four aligned panels, the lateral belt obtained 8 ( figure 3 ) has a polygonal cross section, in this case rectangular, with two large panels 3, 5 and two small panels 2, 4. Of course, the blank 1 could have a different number of panels, but four is the most desired configuration for obtaining a lateral belt 8 and, consequently, a parallelepipedic container 9 such as that illustrated in FIG. figure 3 and consisting of a stack of four interlocked lateral belts, superimposed.

Conformément à l'invention, le flan présente, du premier côté supérieur 10 de la suite de panneaux, des évidements 11 qui sont découpés préalablement dans le flan et qui sont situés au niveau des angles de chaque panneau. Ces évidements 11 sont identiques et de contour rectangulaire et sont disposés ainsi symétriquement l'un par rapport à l'autre sur chaque panneau. Les panneaux 2, 3, 4 et 5 liés par les lignes de pliage 6 ont ainsi les évidements 11 dans le prolongement l'un de l'autre mais agencés symétriquement par rapport à la ligne de pliage correspondante.According to the invention, the blank has, on the first upper side 10 of the series of panels, recesses 11 which are cut beforehand in the blank and which are located at the corners of each panel. These recesses 11 are identical and rectangular in outline and are thus symmetrically arranged relative to each other on each panel. The panels 2, 3, 4 and 5 linked by the fold lines 6 and have the recesses 11 in the extension of one another but arranged symmetrically with respect to the corresponding fold line.

Des rabats latéraux de renfort 12 prolongent, par ailleurs, les panneaux 2, 3, 4, 5 de ce premier côté supérieur 10 de la suite. Pour cela, les rabats latéraux de renfort 12 sont articulés aux panneaux correspondants 2, 3, 4, 5 autour de deuxièmes lignes de pliage alignées 14, perpendiculaires aux premières lignes de pliage 6. Et on voit sur la figure 1, que les rabats latéraux 12 s'étendent approximativement tout du long de leurs panneaux respectifs en passant sur les évidements 11. La hauteur H de ces rabats latéraux de renfort est, dans cet exemple, légèrement supérieure à la profondeur P des évidements comme on le verra ultérieurement.Lateral reinforcing flaps 12 extend, moreover, the panels 2, 3, 4, 5 of this first upper side 10 of the suite. For this, the lateral reinforcement flaps 12 are articulated to the corresponding panels 2, 3, 4, 5 around aligned second fold lines 14, perpendicular to the first fold lines 6. And we see on the figure 1 , that the side flaps 12 extend approximately all along their respective panels by passing over the recesses 11. The height H of these side reinforcement flaps is, in this example, slightly greater than the depth P of the recesses as it is will see later.

Et du second côté alors inférieur 15 de la suite, se trouvent des tenons latéraux 16 qui font saillie des angles desdits panneaux de manière opposée aux évidements 11. Ainsi, les tenons 16 sont situés en correspondance des évidements 11 et ils ont une forme complémentaire de celle des évidements. Chaque panneau 2, 3, 4 et 5 comporte ainsi deux évidements 11 du côté supérieur 10 du flan 1 et deux tenons 16 du côté inférieur 15, agencés aux angles de chacun d'eux.And the second then lower side 15 of the suite, there are lateral tenons 16 which project from the corners of said panels opposite to the recesses 11. Thus, the tenons 16 are located in correspondence of the recesses 11 and they have a shape complementary to that of the recesses. Each panel 2, 3, 4 and 5 thus has two recesses 11 on the upper side 10 of the blank 1 and two pins 16 on the lower side 15, arranged at the corners of each of them.

La hauteur H1 des tenons 16 est au plus égale à la profondeur P des évidements pour un emboîtement approprié comme on le verra ultérieurement.The height H1 of the studs 16 is at most equal to the depth P of the recesses for an appropriate interlocking as will be seen later.

De plus, du côté supérieur 15 du flan 1 sont prévues des languettes 17 issues respectivement des grands panneaux 3, 5, et situées sensiblement au centre de ceux-ci. Ces languettes 17, desquelles part de chaque côté la deuxième ligne de pliage 14, s'avancent dans les rabats de renfort correspondants 12 et une ligne de découpe 18 les sépare de ceux-ci. La fonction de ces languettes sera définie plus tard.In addition, on the upper side 15 of the blank 1 are provided tabs 17 respectively from the large panels 3, 5, and located substantially in the center thereof. These tongues 17, from which on each side the second fold line 14, advance into the corresponding reinforcing flaps 12 and a cutting line 18 separates them from them. The function of these tabs will be defined later.

La mise en forme de la ceinture latérale 8 à partir du flan 1 se déroule de la façon suivante.The shaping of the side belt 8 from the blank 1 takes place as follows.

On applique sur le tenon transversal 7 un adhésif puis on replie les différents panneaux 2, 3, 4 et 5 du flan de 90° les uns à la suite des autres autour des premières lignes de pliage 6, pour effectuer ensuite le collage des deux bords libres du flan 1 par l'adhésif du tenon. La ceinture latérale obtenue 8 présente une section transversale rectangulaire avec les panneaux, grands 3, 5 et petits 2,4, opposés deux à deux. Puis, on replie les rabats latéraux de renfort 12 autour des deuxièmes lignes de pliage 14 d'un angle de 180°, vers l'intérieur de ladite ceinture 8, jusqu'à ce qu'ils viennent contre les panneaux respectifs 2 à 5. La fixation des rabats latéraux ainsi repliés contre les panneaux s'effectue là aussi par collage. Comme le montrent les figures 3 et 4, les rabats de renfort repliés 12 constituent une surépaisseur de matière en partie supérieure de la ceinture 8 depuis le bord supérieur périphérique 19 de celle-ci jusqu'au-delà des évidements 11 formés aux coins de la ceinture, lesquels sont obturés en totalité par les rabats de renfort 12 qui se prolongent au-delà des évidements (H>P). Cette surépaisseur apportée par les rabats de renfort 12, au niveau de leur pliage autour des lignes 14 contre les panneaux, consolide ainsi tout le pourtour supérieur de la ceinture y compris au niveau des évidements 11 des panneaux. Le bord supérieur 19 des ceintures a, à ce niveau, une épaisseur double (panneau + rabat), à l'exception des zones évidées 11 où seuls les rabats de renfort sont adossés en constituant ainsi un guidage et un maintien pour les tenons s'engageant dans les évidements.A adhesive is applied to the transverse post 7, then the various panels 2, 3, 4 and 5 of the blank are folded by 90 ° one after the other around the first fold lines 6, then to glue the two edges together. free of the blank 1 by the tenon adhesive. The resulting lateral belt 8 has a rectangular cross section with the panels, large 3, 5 and small 2.4, opposite two by two. Then, the side reinforcing flaps 12 are folded around the second folding lines 14 at an angle of 180 °, towards the inside of said belt 8, until they come against the respective panels 2 to 5. Fixing the side flaps thus folded against the panels is also done by gluing. As shown by figures 3 and 4 , the folded reinforcement flaps 12 constitute an extra material thickness in the upper part of the belt 8 from the peripheral upper edge 19 thereof to beyond the recesses 11 formed at the corners of the belt, which are completely closed by the reinforcing flaps 12 which extend beyond the recesses (H> P). This extra thickness provided by the reinforcement flaps 12, at their folding around the lines 14 against the panels, thus consolidates the entire upper periphery of the belt including the recesses 11 of the panels. The upper edge 19 of the belts has, at this level, a double thickness (panel + flap), with the exception of the recessed areas 11 where only the reinforcement flaps are backed thus constituting a guide and a support for the tenons s'. engaging in the recesses.

On remarque aussi que le repliement des rabats 12 des grands panneaux 3, 5 a permis de mettre à jour les languettes centrales 17 grâce à la ligne de découpe 18 de chaque languette, ménagée précédemment.Note also that the folding of the flaps 12 large panels 3, 5 has updated the central tabs 17 through the cutting line 18 of each tab, made previously.

On voit en outre, sur les figures 3 et 4, que les tenons saillants 16 issus du bord inférieur 20 au niveau du second côté inférieur 15 de la ceinture 8, forment, par leur pliage autour des premières lignes verticales 6, des pieds coudés à 90° aux coins de ladite ceinture. Ces pieds coudés vont avantageusement s'inscrire respectivement dans les évidements coudés 11 aux coins d'une ceinture latérale inférieure, en étant guidés et maintenus par les rabats repliés 12.In addition, we see figures 3 and 4 , that the projecting lugs 16 from the lower edge 20 at the second lower side 15 of the belt 8, form, by their folding around the first vertical lines 6, feet bent at 90 ° at the corners of said belt. These bent legs will advantageously register respectively in the bent recesses 11 at the corners of a lower side belt, being guided and held by the folded flaps 12.

Plusieurs ceintures latérales 8 sont ainsi empilées progressivement les unes sur les autres en fonction des besoins, comme le montre la figure 3, pour former le container représenté 9 qui peut comporter un nombre quelconque de ceintures.Several side belts 8 are thus stacked progressively over each other as needed, as shown in FIG. figure 3 to form the container shown 9 which may comprise any number of belts.

Les liaisons tenons 16 - évidements 11 situés dans les coins des ceintures assurent non seulement un bon emboîtement des ceintures les unes sur les autres, mais le fait qu'elles soient renforcées par les rabats 12 garantit un maintien en déplacements latéraux grâce à la présence de la surépaisseur des rabats. Entre les évidements 11, le bord supérieur 19 des ceintures est doublé en épaisseur par les rabats de renfort 12 contre les panneaux 2, 3, 4 et 5, de sorte à garantir une rigidité appropriée à la superposition des ceintures.The 16-recess links 11 located in the corners of the belts ensure not only a good interlocking of the belts on each other, but the fact that they are reinforced by the flaps 12 ensures a lateral displacement maintained through the presence of the extra thickness of the flaps. Between the recesses 11, the upper edge 19 of the belts is doubled in thickness by the reinforcing flaps 12 against the panels 2, 3, 4 and 5, so as to ensure rigidity appropriate to the superposition of the belts.

Si les ceintures latérales empilées 8 sont identiques entre elles, en revanche, la ceinture latérale de base 8.1 venant au contact d'une palette ou analogue 23 faisant office de fond pour le container 9, est quelque peu différente. En effet, comme le montre la figure 2, le flan 1.1 représenté comporte, au niveau du second côté inférieur 15 de la suite de panneaux, des rabats latéraux 24 reliés auxdits panneaux 2, 3, 4, 5 par des troisièmes lignes de pliage 25 parallèles aux deuxièmes lignes 14. On voit que ces rabats 24 s'étendent entre les deux tenons correspondants 16 des panneaux en étant bien sûr séparés de ceux-ci et que leur hauteur est identique à celle H1 des tenons. Cependant, elle pourrait être différente et suffisamment grande pour que ces rabats 24 forment le fond du container.If the stacked side belts 8 are identical to each other, on the other hand, the base lateral belt 8.1 coming into contact with a pallet or the like 23 serving as a bottom for the container 9, is somewhat different. Indeed, as shown in figure 2 , the blank 1.1 shown has, at the second lower side 15 of the series of panels, side flaps 24 connected to said panels 2, 3, 4, 5 by third fold lines 25 parallel to the second lines 14. It is seen that these flaps 24 extend between the two corresponding posts 16 of the panels being of course separate from those and that their height is identical to that H1 tenons. However, it could be different and large enough for these flaps 24 to form the bottom of the container.

Ainsi, en repliant vers l'intérieur de la ceinture latérale formée 8.1 comme précédemment, les rabats 24 autour des troisièmes lignes de pliage 25, ceux-ci font servir de surfaces d'appui sur la palette, comme le montre la figure 5. Comme certains des objets ou caisses d'objets 27 à charger dans la ceinture latérale 8.1 ainsi déposé sur la palette, vont reposer en partie sur les rabats 24, la ceinture ainsi « pincée » est stabilisée à ce niveau par les objets et la palette. Bien entendu, comme on le voit sur les figures 3 et 5, la forme périphérique de la palette 23 correspond sensiblement à celle de la ceinture de base 8.1, de manière que les pieds 21 de celle-ci s'emboîtent autour des coins de la palette, garantissant la bonne tenue du container 9.Thus, by folding inwardly of the lateral belt formed 8.1 as before, the flaps 24 around the third fold lines 25, they serve as bearing surfaces on the pallet, as shown in FIG. figure 5 . As some of the objects or crates of objects 27 to be loaded into the lateral belt 8.1 thus deposited on the pallet, will rest in part on the flaps 24, the belt thus "pinched" is stabilized at this level by the objects and the pallet. Of course, as we see on the figures 3 and 5 , the peripheral shape of the pallet 23 corresponds substantially to that of the base belt 8.1, so that the feet 21 of the latter fit around the corners of the pallet, ensuring the good performance of the container 9.

Les ceintures peuvent aussi reposer sur le sol par les pieds coudés formés des tenons.The belts can also rest on the ground by the angled feet formed tenons.

Par ailleurs, les languettes latérales 17 participent également au maintien des ceintures latérales 8 ainsi empilées les unes sur les autres, et évitent la déformation des grands panneaux 3, 5, ceux-ci restant parallèles entre eux en évitant de s'écarter.Furthermore, the lateral tabs 17 also participate in maintaining the side belts 8 and stacked on each other, and prevent deformation of the large panels 3, 5, they remaining parallel to each other avoiding to deviate.

Une fois utilisée, chaque ceinture peut être retirée aisément et mise à plat en la pliant pour cela en diagonale autour de deux lignes opposées 6 pour un stockage à volume minimal.Once used, each belt can be removed easily and flattened by diagonally folding it around two opposite lines 6 for minimal volume storage.

Le container réalisé par la superposition de plusieurs ceintures latérales emboîtées, obtenues à partir des flans, permet une économie de matière importante (un seul flan avec évidements, tenons et rabats de renfort) comparativement à la réalisation antérieure tout en conservant la rigidité nécessaire à la bonne stabilité du container à l'usage.The container made by the superposition of several nested side belts, obtained from the blanks, allows a significant saving of material (a single blank with recesses, tenons and reinforcement flaps) compared to the previous embodiment while retaining the rigidity necessary for the good stability of the container in use.
