Description

La présente invention est relative à un dispositif conteneur empilable.The present invention relates to a stackable container device.

Plus particulièrement, l'invention concerne un dispositif conteneur empilable comportant un plateau ayant un fond horizontal, deux parois longitudinales et deux parois transversales pleines, le dispositif conteneur comprenant en outre deux trottoirs transversaux qui sont orientés horizontalement côté intérieur du plateau en déterminant, avec une tranche supérieure horizontale des parois du plateau à ses coins au raccordement des parois longitudinales et transversales, un appui de gerbage.More particularly, the invention relates to a stackable container device comprising a plate having a horizontal bottom, two longitudinal walls and two full transverse walls, the container device further comprising two transverse sidewalks which are oriented horizontally on the inside of the plate by determining, with a top horizontal slice of the walls of the plate at its corners at the connection of the longitudinal and transverse walls, a stacking support.

Un exemple de ce genre de dispositif est connu du document EP0870689 qui divulgue l'utilisation de trottoirs rattachés avec pliage aux parois transversales et fixés aux extrémités des parois longitudinales. Les trottoirs sont intégrés au plateau. Des plaques transversales d'extrémité peuvent être glissées sous les trottoirs. Chaque plaque a trois volets dont un volet central est en correspondance d'une partie centrale de la paroi transversale correspondante et des volets latéraux sont inclinés sous les trottoirs, du volet central vers les parois longitudinales. Le haut et le bas des volets latéraux sont découpés en biais pour s'ajuster sur des angles supérieurs en chanfrein du plateau. Le montage de ces plaques transversales d'extrémité est relativement complexe car il nécessite de bien maîtriser les dispersions dimensionnelles du plateau comme desdites plaques, même si les chanfreins du plateau et les découpes en biais des plaques transversales peuvent faciliter le centrage des plaques. Par ailleurs, outre la nécessité de bien maîtriser les jeux d'insertion, glisser les plaques sous les trottoirs est une opération qui peut s'avérer délicate pour être automatisée. En effet, les trottoirs peuvent constituer des obstacles pour l'insertion des plaques. D'autres dispositifs conteneur sont connus des documents WO 88/02724 , GB 09467 , FR 1 358 881 et US 2010/247272 . La présente invention a notamment pour but d'améliorer les solutions existantes et/ou de proposer des alternatives.An example of this kind of device is known from the document EP0870689 which discloses the use of sidewalks attached with folding to the transverse walls and fixed to the ends of the longitudinal walls. Sidewalks are integrated into the plateau. Cross end plates can be slid under the sidewalks. Each plate has three flaps, a central flap is in correspondence of a central portion of the corresponding transverse wall and side flaps are inclined under the sidewalks, the central flap to the longitudinal walls. The top and bottom of the side flaps are cut at an angle to fit at higher angles in the chamfer of the tray. The mounting of these transverse end plates is relatively complex because it requires good control of the dimensional dispersions of the plate like said plates, even if the chamfers of the plate and the cut-outs of the transverse plates can facilitate the centering of the plates. Moreover, in addition to the need to master the insertion games, slipping the plates under the sidewalks is an operation that can be tricky to be automated. Indeed, the sidewalks can be obstacles for the insertion of the plates. Other container devices are known documents WO 88/02724 , GB 09467 , FR 1 358 881 and US 2010/247272 . The present invention is intended in particular to improve existing solutions and / or to propose alternatives.

Outre les contraintes exprimées ci-dessus en relation avec l'une des solutions du document EP0870689 , d'autres contraintes peuvent être prises en compte quand il s'agit de proposer des dispositifs conteneur à forte résistance mécanique à l'empilement. Il est bien de renforcer des plateaux à gerber, en particulier pour des produits tels que des fruits et légumes relativement denses qui augmentent les contraintes lors de l'empilage vertical desdits plateaux, mais encore faut-il ne pas trop complexifier leur structure ou leur mode de conformation.In addition to the constraints expressed above in relation to one of the solutions of the document EP0870689 , other constraints can be taken into account when it comes to proposing container devices with high mechanical resistance to stacking. It is well to reinforce trays to be stacked, especially for products such as relatively dense fruits and vegetables which increase the stresses during the vertical stacking of said trays, but it is necessary not to overly complex their structure or their mode. of conformation.

A cet effet, l'invention a pour objet un dispositif conteneur empilable selon la revendication 1. Dans divers modes de réalisation du dispositif conteneur selon l'invention, on peut éventuellement avoir recours en outre à l'une et/ou à l'autre des dispositions suivantes :

  • le pan de fixation s'étend verticalement vers le bas ;

  • le pan de fixation est fixé à la face interne de la paroi transversale correspondante ;
  • chaque dispositif de renfort est rapporté dans le plateau et présente d'une part un pan principal s'étendant au regard de l'ensemble de la paroi transversale correspondante du plateau, à partir du fond du plateau et jusqu'à la tranche supérieure du plateau et d'autre part son pan intermédiaire qui est raccordé en haut du pan principal ainsi que son pan de fixation qui est fixé à la face interne du pan principal ;
  • chaque dispositif de renfort rapporté comprend deux languettes latérales raccordées verticalement aux extrémités libres latérales du pan principal en étant contre une face intérieure des parois longitudinales du plateau ;
  • les deux languettes latérales s'étendent verticalement à partir du fond du plateau et jusqu'à la tranche supérieure du plateau ;
  • chaque dispositif de renfort rapporté est en carton d'épaisseur différente de l'épaisseur du plateau le recevant.
For this purpose, the invention relates to a stackable container device according to claim 1. In various embodiments of the container device according to the invention, one or more of the following provisions may also be used:
  • the attachment panel extends vertically downwards;
  • the sidewalk is connected to the corresponding transverse wall being in the material continuity of the transverse wall and folded perpendicular to the transverse wall;
  • the attachment panel is fixed to the inner face of the corresponding transverse wall;
  • each reinforcement device is attached to the tray and has on the one hand a main panel extending with respect to the entire corresponding transverse wall of the tray, from the bottom of the tray to the upper edge of the tray and on the other hand its intermediate panel which is connected at the top of the main panel and its attachment panel which is fixed to the internal face of the main panel;
  • each reinforcing device reported comprises two lateral tongues connected vertically to the free lateral ends of the main panel while being against an inner face of the longitudinal walls of the plate;
  • the two lateral tongues extend vertically from the bottom of the plate and up to the upper edge of the plate;

En se reportant aux figures, la référence 10 désigne un dispositif conteneur selon l'invention, comprenant un plateau 12 en carton et deux dispositifs de renfort 13. Sur les différentes figures, les mêmes références désignent des éléments identiques ou similaires. Le plateau et les dispositifs de renfort sont indiqués comme étant en carton mais ils peuvent être dans tout matériau semi rigide ayant des propriétés équivalentes de résistance mécanique et d'aptitude au pliage.Referring to the figures, reference numeral 10 denotes a container device according to the invention, comprising a cardboard tray 12 and two reinforcing devices 13. In the various figures, the same references designate identical or similar elements. The tray and reinforcing devices are indicated as being made of cardboard, but they may be in any semi-rigid material having equivalent properties of strength and bendability.

Dans le mode de réalisation représentée en exemple aux figures, le dispositif conteneur 10 est sensiblement à base parallélépipédique rectangle en ayant son plateau 12 qui comporte un fond horizontal 12D rectangulaire dont la longueur détermine la direction qualifiée de longitudinale dans la présente description et la largeur correspond à la direction qualifiée de transversale dans la présente description. La hauteur du plateau est par exemple d'environ un tiers de la largeur du plateau. Le dispositif conteneur sert donc de référentiel pour définir la direction longitudinale est la direction transversale.In the embodiment represented as an example in the figures, the container device 10 is substantially rectangle-based rectangular base having its plate 12 which has a rectangular horizontal bottom 12D whose length determines the direction qualified longitudinal in the present description and the width corresponds to the qualified management of transverse in the present description. The height of the tray is for example about one third of the width of the tray. The container device thus serves as a reference to define the longitudinal direction is the transverse direction.

Un tel plateau 12 présente des dimensions habituelles pour contenir typiquement des fruits ou des légumes. Par exemple un tel plateau peut contenir des melons. Pour le transport des melons, lorsque des dispositifs conteneurs sont empilés, leur résistance à la compression verticale doit être importante car les melons sont des produits relativement denses et lourds. En effet, les plateaux ainsi gerbés par exemple sur une palette doivent supporter, en particulier pour ceux qui sont au-dessous de l'empilement, une masse très importante compte tenu de la masse des plateaux remplis et disposés jusqu'en haut de l'empilement.Such a tray 12 has the usual dimensions to typically contain fruits or vegetables. For example, such a tray may contain melons. For the transport of melons, when container devices are stacked, their vertical compressive strength must be important because melons are relatively dense and heavy products. Indeed, trays thus stacked for example on a pallet must withstand, especially for those below the stack, a very large mass given the mass of trays filled and arranged to the top of the stack.

Les dispositifs conteneur 10 selon l'invention sont empilables et sont destinés à cet usage, avec les contraintes expliquées ci-dessus. Chaque dispositif conteneur 10 a son plateau 12 qui comporte deux parois longitudinales 12L et deux parois transversales 12T qui sont pleines. Ces parois transversales 12T sont sensiblement rectangulaires et sont pleines en étant raccordées verticalement aux parois longitudinales 12L et horizontalement à la paroi de fond 12D. Le plateau 12 est en carton à cannelures parallèles qui sont disposées longitudinalement. Dans les parois transversales 12T, les cannelures sont alignées verticalement pour une bonne résistance à la compression verticale des parois transversales. Les dispositifs de renfort 13 sont également constitués de cartons à cannelures parallèles qui sont disposées parallèlement aux cannelures du plateau.The container devices 10 according to the invention are stackable and are intended for this use, with the constraints explained above. Each container device 10 has its plate 12 which has two longitudinal walls 12L and two transverse walls 12T which are solid. These transverse walls 12T are substantially rectangular and are solid by being connected vertically to the longitudinal walls 12L and horizontally to the bottom wall 12D. The plate 12 is in cardboard with parallel grooves which are arranged longitudinally. In the transverse walls 12T, the grooves are aligned vertically for good resistance to the vertical compression of the transverse walls. The reinforcing devices 13 also consist of parallel corrugated cardboards which are arranged parallel to the splines of the plate.

Les deux parois transversales 12T du plateau sont pourvues chacune d'au moins un tenon supérieur 16 de calage de gerbage en saillie de la tranche supérieure horizontale des parois transversales. Dans la pratique, les dimensions des tenons 16 sont standardisées, tout comme les emplacements de ces tenons. Ainsi, les différents fabricants de plateaux destinés à être gerbés utilisent ces dimensions et ces emplacements de type standard. Le plateau 12 comprend une encoche 18 aménagée au raccordement du fond 12D du plateau et de chaque paroi transversale 12T pour réception d'un tenon 16 de calage de gerbage correspondant quand des plateaux sont gerbés.The two transverse walls 12T of the plate are each provided with at least one upper pin 16 stacking wedge projecting from the upper edge horizontal transverse walls. In practice, the dimensions of the studs 16 are standardized, as are the locations of these studs. Thus, the various manufacturers of trays intended to be stacked use these dimensions and these locations of standard type. The plate 12 comprises a notch 18 arranged at the connection of the bottom 12D of the plate and each transverse wall 12T for receiving a pin 16 corresponding stacking stall when trays are stacked.

Le plateau 12 a ses parois longitudinales 12L qui déterminent un évidement vertical 12V sur une partie de la longueur et sur une partie de la hauteur du plateau, centré au milieu de la longueur de cette paroi longitudinale. Chaque évidement vertical 12V est ouvert avec évasement en haut du plateau, au-dessus d'une zone centrale du bas de la paroi longitudinale. Un tel évidement 12V est de type classique et ne mérite pas être détaillé. Par ailleurs, les parois longitudinales 12L sont équipées en haut de leur effacement 12V d'un rabat supérieur 12R qui ne mérite pas non plus d'être décrit plus en détail.The plate 12 has its longitudinal walls 12L which determine a vertical recess 12V over part of the length and over part of the height of the plate, centered in the middle of the length of this longitudinal wall. Each vertical recess 12V is open flared at the top of the tray, above a central zone of the bottom of the longitudinal wall. Such a recess 12V is of conventional type and does not deserve to be detailed. Furthermore, the longitudinal walls 12L are equipped at the top of their 12V erasure of an upper flap 12R which also does not deserve to be described in more detail.

Le plateau 12 est issu d'un flan initialement plan comme la figure 2 le représente. Chaque paroi longitudinale 12L comporte un mur latéral externe 22 qui est sur toute la longueur du plateau et sur toute la hauteur du plateau excepté à la partie centrale du haut du mur latéral externe qui détermine l'évidement vertical. De plus, chaque paroi longitudinale 12L comporte deux panneaux intérieurs 24 qui sont initialement rattachés à chaque extrémité latérale de chaque paroi transversale 12T. Le raccordement de chaque panneau intérieur 24 avec ses parois transversales 12T se fait par pliage suivant une ligne de pliage vertical 26. La figure 2 montre très bien chaque ligne de pliage 26 sur la plaque initiale déterminant le flanc en carton servant de base pour la construction du plateau. Chaque panneau intérieur 24 est sur une partie de la longueur de la paroi longitudinale 12L correspondante et sur toute la hauteur de cette paroi longitudinale à ces zones d'extrémité qui sont longitudinalement de chaque côté de la zone centrale en bas de la paroi longitudinale.The plate 12 is derived from an initially planar blank such as figure 2 represents him. Each longitudinal wall 12L has an outer lateral wall 22 which is along the entire length of the plate and over the entire height of the plate except at the central portion of the top of the outer lateral wall which determines the vertical recess. In addition, each longitudinal wall 12L has two inner panels 24 which are initially attached to each lateral end of each transverse wall 12T. The connection of each inner panel 24 with its transverse walls 12T is done by folding along a vertical fold line 26. The figure 2 shows very well each fold line 26 on the initial plate determining the cardboard side used as a base for the construction of the plate. Each inner panel 24 is on a part of the length of the longitudinal wall 12L corresponding and over the entire height of the longitudinal wall at these end zones which are longitudinally on each side of the central zone at the bottom of the longitudinal wall.

A chaque extrémité du plateau, une tranche supérieure 28 est horizontale en étant déterminée par les faces supérieures des parois du plateau à ses coins au raccordement des parois longitudinales et transversales. Ces coins présentent les lignes de pliage vertical 26. Chaque tranche supérieure 28 définit un appui de gerbage en haut des zones d'extrémité des parois longitudinales 12L et en haut des parois transversales 12T au centre desquelles les tenons 28 aménagent une interruption de cette tranche supérieure.At each end of the plate, an upper edge 28 is horizontal being determined by the upper faces of the tray walls at its corners at the connection of the longitudinal and transverse walls. These corners have the vertical fold lines 26. Each upper edge 28 defines a stacking support at the top of the end regions of the longitudinal walls 12L and at the top of the transverse walls 12T at the center of which the tenons 28 provide an interruption of this upper edge .

Le dispositif conteneur comprend en outre deux trottoirs transversaux 30 qui sont orientés sensiblement horizontalement en déterminant, avec la tranche 28 supérieure horizontale des parois du plateau à ses coins au raccordement des parois longitudinales et transversales, un appui de gerbage. Les trottoirs transversaux 30 sont adjacents aux extrémités supérieures des parois transversales 12T, ces faces supérieures constituant des portions de la tranche supérieure 28 du plateau. Les trottoirs transversaux 30 sont orientés du côté intérieur du plateau à partir desdites faces supérieures. Les trottoirs transversaux 30 peuvent être légèrement inclinés de quelques degrés vers le bas et vers l'intérieur du plateau.The container device further comprises two transverse sidewalks 30 which are oriented substantially horizontally by determining, with the upper horizontal edge 28 of the walls of the plate at its corners at the connection of the longitudinal and transverse walls, a stacking support. The transverse sidewalks 30 are adjacent to the upper ends of the transverse walls 12T, these upper faces constituting portions of the upper edge 28 of the plate. The transverse sidewalks 30 are oriented on the inside of the tray from said upper faces. The transverse sidewalks 30 may be slightly inclined a few degrees downwardly and inwardly of the tray.

Le plateau 12 est conformé à partir du flan par pliage des murs latéraux externes 22 suivant un axe de pliage horizontal de manière à ramener chaque mur latéral externe 22 perpendiculairement au fond 12D du plateau. Chaque panneau intérieur 24 est rabattu perpendiculairement à sa paroi transversale 12T, par pliage suivant la ligne 26 de pliage correspondante. Enfin, chaque paroi transversale 12T équipée de ses panneaux intérieurs 24 rabattus à angle droit est pliée suivant un axe de pliage horizontal de manière à ramener chaque paroi transversale 12T perpendiculairement au fond 12D du plateau pendant que les panneaux intérieurs 24 sont glissés parallèlement aux murs latéraux 22, le long des faces intérieures de ces murs. Les panneaux intérieurs 24 sont collés aux zones d'extrémités correspondantes des murs latéraux externes 22. Un tel collage est classique. Le processus de conformation du plateau 12 peut être effectué en utilisant une machine classique de conformation.The plate 12 is shaped from the blank by folding the outer lateral walls 22 along a horizontal folding axis so as to bring each external lateral wall 22 perpendicular to the bottom 12D of the plate. Each inner panel 24 is folded perpendicularly to its transverse wall 12T, by folding along the corresponding fold line 26. Finally, each transverse wall 12T equipped with its interior panels 24 folded at right angles is folded along a horizontal folding axis so as to bring each transverse wall 12T perpendicularly to the bottom 12D of the tray while the inner panels 24 are slid parallel to the side walls 22, along the inner faces of these walls. The inner panels 24 are bonded to the corresponding end regions of the outer side walls 22. Such bonding is conventional. The shaping process of the tray 12 can be performed using a conventional shaping machine.

De manière générale, en correspondance de chaque paroi transversale pleine 12T du plateau, chacun des dispositifs de renfort 13 est pourvu d'une part d'un pan 30 s'étendant à angle droit par rapport à la paroi transversale 12T correspondante en constituant le trottoir correspondant et d'autre part de deux pans pliés de rattachement du pan de trottoir 30 au sein du dispositif conteneur en stabilisant ce trottoir horizontalement au niveau de la tranche supérieure horizontale 28. Ces pans pliés comprennent un pan intermédiaire 37 s'étendant sous le trottoir et un pan de fixation 39 s'étendant verticalement à partir du pan intermédiaire en étant stable relativement à la paroi transversale correspondante.In general, corresponding to each full transverse wall 12T of the plate, each of the reinforcing devices 13 is provided on the one hand with a panel 30 extending at right angles to the corresponding transverse wall 12T constituting the sidewalk. corresponding and on the other hand two folded panels connecting the sidewalk 30 within the container device stabilizing the sidewalk horizontally at the level of the upper horizontal edge 28. These folded sides include an intermediate section 37 extending under the sidewalk and a bracket 39 extending vertically from the intermediate pan being stable relative to the corresponding transverse wall.

Dans le premier mode de réalisation tel que représenté de la figure 1 à la figure 6, les deux dispositifs de renfort 13 sont des pièces en carton qui sont rapportées dans le plateau. Chaque dispositif de renfort 13 destiné à être rapporté dans le plateau 12 présente d'une part un pan principal 33 et d'autre part, raccordé en haut du pan principal, le trottoir 30 qui est constitué par un pan replié à angle droit par rapport au pan principal.In the first embodiment as shown in FIG. figure 1 to the figure 6 , the two reinforcing devices 13 are cardboard pieces that are reported in the tray. Each reinforcing device 13 intended to be attached to the plate 12 has on the one hand a main part 33 and, on the other hand, connected at the top of the main part, the sidewalk 30 which is constituted by a folded bent at right angles to to the main pan.

Chaque dispositif de renfort 13 rapporté comprend une échancrure 35 aménagée pour la réception, quand les dispositifs conteneurs 10 sont empilés, du tenon de gerbage 16 correspondant qui appartient au dispositif conteneur 10 adjacent au-dessous du dispositif de renfort 13 considéré. Ce tenon 16, en coopérant par engagement dans l'échancrure 35 et dans l'encoche 18 correspondante du plateau permet le calage des dispositifs conteneurs gerbés.Each reinforcement device 13 includes a notch 35 arranged for receiving, when the container devices 10 are stacked, the corresponding stacking pin 16 which belongs to the device adjacent container 10 below the reinforcing device 13 considered. This tenon 16 cooperating by engagement in the notch 35 and in the corresponding notch 18 of the plate allows the wedging of the stacked containers.

Chaque dispositif de renfort 13 a ses organes de rattachement qui, de manière additionnelle au rattachement avec le pan principal 33, permettent la fixation du trottoir au sein du dispositif conteneur en fixant le trottoir horizontalement. Les organes de rattachement permettent de bloquer les pans de trottoir 30 en position horizontale relativement au reste du dispositif conteneur, afin d'éviter l'affaissement des trottoirs lorsque ces dispositifs sont empilés.Each reinforcing device 13 has its attachment members which, in addition to attachment to the main panel 33, allow the attachment of the sidewalk within the container device by securing the sidewalk horizontally. The attachment members are used to block the curb sections 30 in a horizontal position relative to the rest of the container device, to prevent the collapse of sidewalks when these devices are stacked.

Ces organes de rattachement additionnel sont sur le même principe général pour les différents modes de réalisation.These additional attachment members are on the same general principle for the different embodiments.

Dans le premier mode de réalisation illustré de la figure 1 à la figure 6, chaque dispositif de renfort 13 rapporté comprend, dans ses organes de rattachement, les deux pans pliés de rattachement du pan de trottoir. Dans ces deux pans, d'une part le pan intermédiaire 37 est destiné à s'étendre sous le trottoir 30 et d'autre part le pan de fixation 39 est destiné à s'étendre vers le bas à partir du pan intermédiaire 37 en étant fixé à la face interne du pan principal 33. Quand le dispositif de renfort 13 est dans le plateau 12, le pan intermédiaire 37 s'étend incliné sous le pan de trottoir 30 en étant orienté, depuis une extrémité libre du pan de trottoir côté intérieur du plateau, d'une part vers le pan principal 33 correspondant et d'autre part vers le fond 12D du plateau.In the first illustrated embodiment of the figure 1 to the figure 6 , each reinforcing device 13 reported includes, in its connecting members, the two folded panels of attachment of the sidewalk. In these two faces, on the one hand, the intermediate section 37 is intended to extend under the sidewalk 30 and, on the other hand, the attachment section 39 is intended to extend downwards from the intermediate section 37 while being attached to the inner face of the main panel 33. When the reinforcing device 13 is in the tray 12, the intermediate panel 37 extends inclined under the sidewalk 30 being oriented, from a free end of the sidewalk side inside of the plate, on the one hand towards the corresponding main panel 33 and on the other hand towards the bottom 12D of the plate.

Le fonctionnement du dispositif conteneur 10 conforme au premier mode de réalisation ressort déjà en partie de la description qui précède et va maintenant être détaillé.The operation of the container device 10 according to the first embodiment is already apparent in part from the foregoing description and will now be detailed.

En première phase d'exemple de montage, comme représenté à la figure 3, les dispositifs de renfort 13 sont positionnés en approche pour leur assemblage au plateau 12. Les dispositifs de renfort 13 sont présentés verticalement, au-dessus et sensiblement dans les plans parallèles aux parois transversales 12T. Les dispositifs de renfort 13 sont alors prêts à être descendus verticalement en direction de la paroi de fond 12D du plateau.In first phase of example of assembly, as represented in figure 3 , the reinforcing devices 13 are positioned in approach for their assembly to the plate 12. The reinforcing devices 13 are presented vertically, above and substantially in the planes parallel to the transverse walls 12T. The reinforcing devices 13 are then ready to be lowered vertically in the direction of the bottom wall 12D of the plate.

En deuxième phase d'exemple de montage, comme représenté à la figure 4, en début de leur assemblage au plateau, les dispositifs de renfort 13 sont positionnés à insertion dans le plateau 12. Ils sont descendus sensiblement parallèlement à la paroi transversale 12T correspondante puis rapprochés par translation horizontale combinée le cas échéant à un pivotement autour d'un axe horizontal pour collage à la face interne de leur paroi transversale. Ainsi, chaque dispositif de renfort 13 est rapporté dans le plateau 12 en ayant son pan principal 33 qui s'étend au regard de l'ensemble de la paroi transversale 12T correspondante du plateau, à partir du fond 12D du plateau et jusqu'à la tranche supérieure 28 du plateau. Avantageusement, les mouvements d'insertion sont relativement simples et permettent une mécanisation via une machine qui peut alors être de conception robuste car peu complexe dans son architecture et de fabrication économique.In second phase of example of assembly, as represented in figure 4 , at the beginning of their assembly to the plate, the reinforcing devices 13 are positioned for insertion into the plate 12. They are lowered substantially parallel to the corresponding transverse wall 12T and then brought together by horizontal translation, where appropriate to a pivoting around a horizontal axis for bonding to the inner face of their transverse wall. Thus, each reinforcing device 13 is attached to the plate 12 while having its main part 33 which extends with respect to the whole of the corresponding transverse wall 12T of the plate, from the bottom 12D of the plate and up to the upper slice 28 of the plateau. Advantageously, the insertion movements are relatively simple and allow mechanization via a machine which can then be of robust design as not very complex in its architecture and economical manufacturing.

En troisième phase d'exemple de montage, le haut des dispositifs de renfort est transformé. Les dispositifs de renfort sont repliés à conformation en direction de l'intérieur du plateau.In third phase of mounting example, the top of the reinforcing devices is transformed. The reinforcing devices are folded conformation towards the interior of the tray.

La figure 5 montre le début du pliage permettant la conformation des trottoirs 30. Ce pliage se fait suivant des pivotements d'axes transversaux et horizontaux. Le trottoir 30 est pivoté relativement à l'extrémité supérieure du pan principal 33, pour venir à une orientation horizontale. Le pan intermédiaire 37 est pivoté par rapport à l'extrémité libre du pan de trottoir 30, à l'opposé du pan principal, pour être orienté de manière inclinée sous le trottoir. Le pan de fixation 39 est pivoté par rapport à l'extrémité libre du pan intermédiaire 37, à l'opposé du trottoir 30, pour être orienté verticalement sous ledit trottoir en étant dirigé vers le bas et positionné contre le pan principal 33 avec collage.The figure 5 shows the beginning of the folding allowing the conformation of sidewalks 30. This folding is done according to pivoting transverse axes and horizontal. The sidewalk 30 is pivoted relative to the upper end of the main panel 33, to come to a horizontal orientation. The intermediate pan 37 is rotated relative to the free end of the curb 30, opposite the main panel, to be inclined oriented under the sidewalk. The attachment panel 39 is pivoted relative to the free end of the intermediate panel 37, opposite the sidewalk 30, to be oriented vertically under said sidewalk being directed downwards and positioned against the main panel 33 with gluing.

Ainsi, comme représenté à la figure 6, l'assemblage du plateau 12 et des dispositifs de renfort 13 est finalisé. En récapitulant, le pan de trottoir 30 est replié à angle droit en étant horizontal et dirigé vers l'intérieur du plateau. Le pan de trottoir 30 est en porte à faux à distance du fond 12D, en affleurement horizontal avec à la tranche supérieure 28 des coins correspondants du plateau.Thus, as represented in figure 6 , the assembly of the plate 12 and reinforcement devices 13 is finalized. Summarizing, the sidewalk 30 is bent at right angles while being horizontal and directed towards the inside of the plate. The sidewalk 30 is cantilevered away from the bottom 12D, flush with the horizontal at the top edge 28 corresponding corners of the plate.

En continuant de récapituler, le pan intermédiaire 37 s'étend sous le trottoir 30 et le pan de fixation 39 s'étend vers le bas à partir du pan intermédiaire 37 en étant fixé à la face interne du pan principal. Le pan intermédiaire 37 est incliné sous le pan de trottoir en étant orienté, depuis une extrémité libre du pan de trottoir côté intérieur du plateau, d'une part vers le pan principal correspondant et d'autre part vers le fond du plateau. Il sert ainsi de jambe de force pour que le trottoir soit rigidifié sur toute sa longueur et garde son orientation horizontale. Le pan de fixation 39 stabilise l'ensemble en position. Pour économiser de la matière, le pan de fixation est de hauteur réduite comme représenté aux figures, le collage permettant une bonne solidité d'assemblage même si le bas du pan de fixation 39 ne vient pas appuyer sur le fond du plateau.Continuing to summarize, the intermediate section 37 extends below the sidewalk 30 and the attachment section 39 extends downwardly from the intermediate section 37 and is attached to the inner face of the main section. The intermediate section 37 is inclined under the sidewalk being oriented, from a free end of the sidewalk side inside the plate, on the one hand to the corresponding main pan and on the other hand to the bottom of the tray. It thus serves as a strut so that the sidewalk is stiffened over its entire length and keeps its horizontal orientation. The attachment panel 39 stabilizes the assembly in position. To save material, the attachment panel is of reduced height as shown in the figures, the bonding for good assembly strength even if the bottom of the attachment panel 39 does not press the bottom of the tray.

Divers avantages peuvent ressortir de la solution de renforcement du plateau utilisant le dispositif de renfort 13 avec son trottoir 30 résistant à l'écrasement vertical. Les trottoirs 30 sont stabilisés en permettant une bonne résistance lors de l'empilement des dispositifs conteneurs.Various advantages may emerge from the deck reinforcement solution using the reinforcing device 13 with its sidewalk 30 resistant to vertical crushing. The sidewalks 30 are stabilized by allowing good resistance when stacking the container devices.

En outre, avec les dispositifs de renfort 13 qui sont rapportés, les pans principaux 33 apportent une amélioration de la résistance à la compression verticale du dispositif conteneur, en doublant les parois transversales du plateau.In addition, with the reinforcing devices 13 that are reported, the main sections 33 provide an improvement in the vertical compressive strength of the container device, by doubling the transverse walls of the tray.

Avantageusement, les dispersions dimensionnelles du plateau comme du dispositif de renfort sont faciles à gérer pour disposer d'un dispositif conteneur empilable qui soit solide et aisé à assembler. De plus, la géométrie du dispositif de renfort favorise l'absence de perte de matière car les chutes sont minimisées.Advantageously, the dimensional dispersions of the plate as the reinforcing device are easy to manage to have a stackable container device that is strong and easy to assemble. In addition, the geometry of the reinforcing device promotes the absence of material loss because the falls are minimized.

Avantageusement, la géométrie du dispositif de renfort intégrant un trottoir permet que ce trottoir prenne peu de place à l'intérieur du plateau. En effet ce trottoir est solide sans être trop volumineux et sans être complexe à maintenir solidement dans le plateau.Advantageously, the geometry of the reinforcing device incorporating a sidewalk allows the sidewalk to take up little space inside the tray. Indeed this sidewalk is solid without being too bulky and without being complex to maintain solidly in the plateau.

Avantageusement, chaque dispositif de renfort rapporté 13 peut avoir une épaisseur différente de l'épaisseur du plateau 12 le recevant. Ainsi, pour disposer d'un dispositif conteneur ayant de bonnes caractéristiques de résistance à la compression verticale, il est possible d'utiliser un plateau de base ayant un carton par exemple relativement fin et des cannelures simples et de choisir d'utiliser un dispositif de renfort rapporté 13 qui soit plus épais et par exemple pourvu de cannelures doubles.Advantageously, each reported reinforcing device 13 may have a thickness different from the thickness of the plate 12 receiving it. Thus, to have a container device having good characteristics of resistance to vertical compression, it is possible to use a base plate having a cardboard for example relatively thin and simple grooves and to choose to use a device of reported reinforcement 13 which is thicker and for example provided with double flutes.

Avantageusement, les dispositifs de renfort 13 ne perturbent pas la bonne utilisation des tenons 16 de calage de gerbage.Advantageously, the reinforcing devices 13 do not interfere with the proper use of the pins 16 of stacking stall.

Le dispositif conteneur peut être conformé en utilisant d'une part une machine de conformation standard pour le plateau et d'autre part une machine de conformation spécifique pour le dispositif de renfort rapporté. Une même machine peut être ajoutée pour conformer le renfort rapporté et l'assembler dans le plateau.The container device may be shaped using firstly a standard shaping machine for the tray and secondly a specific shaping machine for the added reinforcement device. A same machine can be added for fit the attached reinforcement and assemble it in the tray.

En variante d'assemblage, le dispositif de renfort rapporté peut avoir son trottoir qui est conformé préalablement à l'assemblage au plateau. Le dispositif de renfort rapporté peut être assemblé à la paroi transversale correspondante du plateau avant que le plateau ne soit conformé, cette conformation du plateau étant effectuée quand les dispositifs de renfort sont déjà ajoutés sur le flan à conformer.As an alternative assembly, the reported reinforcement device may have its sidewalk which is shaped prior to assembly to the plate. The added reinforcement device can be assembled to the corresponding transverse wall of the tray before the tray is shaped, this conformation of the tray being performed when the reinforcing devices are already added to the blank to be conformed.

L'assemblage des dispositifs de renfort dans le plateau peut être réalisé de manière assez flexible, sachant que le plateau peut être de type standard. Par exemple, le pan principal de chaque dispositif de renfort peut être descendu sensiblement verticalement, plus ou moins en parallèle de la paroi transversale correspondante du plateau puis, lorsque le bas du pan principal est à l'approche du fond ou le touche, le dispositif de renfort peut être plaqué latéralement contre la paroi transversale avec collage.The assembly of the reinforcing devices in the tray can be made quite flexible, knowing that the tray can be standard type. For example, the main panel of each reinforcing device can be lowered substantially vertically, more or less parallel to the corresponding transverse wall of the plate and, when the bottom of the main panel is approaching the bottom or the key, the device reinforcement can be plated laterally against the transverse wall with gluing.

La mécanisation de l'assemblage peut être modulaire, en conservant par exemple une machine de conformation du plateau existante pour plateau standard. Cette mécanisation peut être peu complexe du fait de mouvements simples d'assemblage du dispositif de renfort dans le plateau.The mechanization of the assembly can be modular, for example by retaining an existing tray forming machine for a standard tray. This mechanization can be difficult because of simple assembly movements of the reinforcing device in the tray.

Dans la variante du premier mode de réalisation tel que représenté de la figure 7 à la figure 11, chaque dispositif de renfort rapporté 13 comprend, en addition à la configuration décrite précédemment, deux languettes latérales 43 qui sont raccordées verticalement aux extrémités libres latérales du pan principal 33. Chaque languette 43 est contre une face intérieure des parois longitudinales du plateau. Une pliure verticale 46 est présente à l'intersection du pan principal 33 et de chaque languette latérale. Les deux languettes latérales 43 s'étendent verticalement à partir du fond 12D du plateau 12 et jusqu'à la tranche supérieure 28 du plateau.In the variant of the first embodiment as shown in FIG. figure 7 to the figure 11 , each added reinforcing device 13 comprises, in addition to the configuration described above, two lateral tongues 43 which are connected vertically to the free lateral ends of the main panel 33. Each tongue 43 is against an inner face of the longitudinal walls of the plate. A vertical bend 46 is present at the intersection of the main panel 33 and each lateral tab. The two lateral tabs 43 extend vertically from the bottom 12D of the plateau 12 and up to the upper edge 28 of the plateau.

En première phase d'exemple de montage, comme représenté à la figure 8, les dispositifs de renfort 13 sont positionnés en approche pour leur assemblage au plateau 12, après pliage des languettes latérales 43 perpendiculairement à leur pan principal adjacent. Les dispositifs de renfort 13 sont présentés verticalement, au-dessus et sensiblement dans les plans parallèles aux parois transversales 12T en ayant les languettes 43 côté intérieur du plateau. Les dispositifs de renfort 13 sont alors prêts à être descendus verticalement en direction de la paroi de fond 12D du plateau, les languettes latérales 43 glissant alors contre les faces intérieures des panneaux intérieurs 24 appartenant aux parois longitudinales 12L du plateau.In first phase of example of assembly, as represented in figure 8 , the reinforcing devices 13 are positioned in approach for their assembly to the plate 12, after folding of the lateral tabs 43 perpendicularly to their adjacent main panel. The reinforcing devices 13 are presented vertically, above and substantially in the planes parallel to the transverse walls 12T having the tabs 43 on the inside of the plate. The reinforcing devices 13 are then ready to be lowered vertically towards the bottom wall 12D of the plate, the lateral tabs 43 then sliding against the inner faces of the inner panels 24 belonging to the longitudinal walls 12L of the plate.

Le reste des opérations d'assemblage s'effectue sur le même principe que décrit auparavant.The rest of the assembly operations are carried out on the same principle as previously described.

En deuxième phase de montage, en début de leur assemblage au plateau, les dispositifs de renfort 13 sont positionnés à insertion dans le plateau 12. Ils sont descendus sensiblement parallèlement à la paroi transversale 12T correspondante puis, quand le bas des pans principaux est proche du fond 12D, les dispositifs de renfort sont rapprochés avec translation horizontale combinée le cas échéant à un pivotement autour d'un axe horizontal pour collage à la face interne de leur paroi transversale. Sur le même principe que précédemment expliqué, chaque dispositif de renfort 13 est rapporté dans le plateau 12 en ayant son pan principal 33 qui s'étend au regard de l'ensemble de la paroi transversale 12T correspondante du plateau.In the second phase of assembly, at the beginning of their assembly to the plate, the reinforcing devices 13 are positioned to be inserted into the plate 12. They are lowered substantially parallel to the corresponding transverse wall 12T and then, when the bottom of the main sections is close to the 12D bottom, the reinforcing devices are close together with horizontal translation combined where appropriate with a pivoting about a horizontal axis for bonding to the inner face of their transverse wall. On the same principle as previously explained, each reinforcing device 13 is attached to the plate 12 having its main part 33 which extends with respect to the whole of the corresponding transverse wall 12T of the plate.

La figure 9 correspond à la figure 4 et montre lesdits renforts 13 à ce début de l'assemblage au plateau. Avantageusement, les mouvements d'insertion sont encore relativement simples. Les languettes latérales 43 triplent l'épaisseur des zones d'extrémités aux coins du dispositif conteneur.The figure 9 corresponds to the figure 4 and shows said reinforcements 13 at the beginning of the assembly to the plate. Advantageously, the insertion movements are still relatively simple. The side tabs 43 triple the thickness of the end zones at the corners of the container device.

Les languettes latérales 43 peuvent être collées sur les parois longitudinales. Si l'encollage des languettes est antérieur à l'insertion du dispositif de renfort 13 dans le plateau 12, la descente dudit renfort est effectuée avec les languettes 43 resserrées vers leur pan principal. Si l'encollage des languettes est postérieur à l'insertion du dispositif renfort 13 dans le plateau 12, pendant l'encollage, les languettes 43 sont resserrées vers leur pan principal en pivotant dans le plateau suivant la pliure 46. Le collage des languettes 43 est effectué avant rabattement des trottoirs 30 vers leur position horizontale de travail.The lateral tabs 43 may be glued to the longitudinal walls. If the gluing of the tongues is prior to the insertion of the reinforcing device 13 in the plate 12, the descent of said reinforcement is performed with the tabs 43 tightened towards their main panel. If the gluing of the tongues is subsequent to the insertion of the reinforcing device 13 in the plate 12, during the gluing, the tongues 43 are tightened towards their main part by pivoting in the plate following the fold 46. The gluing of the tongues 43 is performed before folding sidewalks 30 to their horizontal working position.

En troisième phase d'exemple de montage, les dispositifs de renfort 13 ont leur haut qui est replié à conformation en direction de l'intérieur du plateau. La figure 10 correspond à la figure 5 et montre le début du pliage permettant la conformation des trottoirs 30. Le pliage se fait suivant les mêmes pivotements d'axes transversaux et horizontaux que ceux décrits auparavant. Le trottoir 30 est pivoté pour venir à une orientation horizontale. Le pan intermédiaire 37 est pivoté par rapport à l'extrémité libre du pan de trottoir 30, pour finir par être incliné sous le trottoir, en passant entre les languettes latérales 43. Le pan de fixation 39 est pivoté par rapport à l'extrémité libre du pan intermédiaire 37, en passant entre les languettes latérales 43 pour finir par être orienté verticalement sous ledit trottoir en étant dirigé vers le bas et positionné contre le pan principal 33 avec collage.In the third phase of mounting example, the reinforcing devices 13 have their top which is folded in conformation towards the inside of the plate. The figure 10 corresponds to the figure 5 and shows the beginning of the folding allowing the conformation of the sidewalks 30. The folding is done according to the same pivoting transverse and horizontal axes as those described previously. The sidewalk 30 is rotated to come to a horizontal orientation. The intermediate section 37 is pivoted relative to the free end of the curb 30, to end up being inclined under the pavement, passing between the lateral tabs 43. The attachment panel 39 is pivoted relative to the free end intermediate panel 37, passing between the lateral tabs 43 to end up being oriented vertically under said sidewalk being directed downwards and positioned against the main panel 33 with gluing.

Ainsi, comme le montre la figure 11, l'assemblage du plateau 12 et des dispositifs de renfort 13 est finalisé. En récapitulant, le pan de trottoir 30 est replié à angle droit en étant horizontal et dirigé vers l'intérieur du plateau. Le pan de trottoir 30 est en porte à faux à distance du fond 12D, en affleurement horizontal avec d'une part la face supérieure des languettes latérales 43 et d'autre part la tranche supérieure 28 des coins correspondants du plateau.So, as shown in figure 11 , the assembly of the plate 12 and reinforcement devices 13 is finalized. Summarizing, the sidewalk 30 is bent at right angles while being horizontal and directed towards the inside of the plate. The sidewalk portion 30 is cantilevered away from the bottom 12D, flush horizontal with firstly the upper face of the lateral tabs 43 and secondly the upper edge 28 corresponding corners of the plate.

Un deuxième mode de réalisation de dispositif conteneur 10 est représenté de la figure 12 à la figure 15, ce dispositif conteneur étant différent du premier mode de réalisation sur quelques caractéristiques. Les dispositifs de renfort 13 sont différents en ayant des pans de trottoir intégrés avec le reste du plateau, sans être rapportés.A second embodiment of the container device 10 is represented by the figure 12 to the figure 15 , this container device being different from the first embodiment on some characteristics. The reinforcing devices 13 are different having sidewalk integrated with the rest of the tray, without being reported.

Ainsi, suivant ce deuxième mode de réalisation, le pan de trottoir 30 est directement raccordé à la paroi transversale 12T correspondante en étant dans la continuité de matière de cette paroi transversale et replié perpendiculairement par rapport à cette paroi transversale. Le pan de fixation 39 est fixé à la face interne de la paroi transversale 12T correspondante.Thus, according to this second embodiment, the sidewalk 30 is directly connected to the corresponding transverse wall 12T being in the material continuity of the transverse wall and folded perpendicularly with respect to this transverse wall. The attachment panel 39 is fixed to the inner face of the corresponding transverse wall 12T.

Pour le deuxième mode de réalisation du dispositif conteneur, les opérations de montage pour l'assemblage des dispositifs de renfort 13 dans le plateau 12 diffèrent peu des opérations décrites en relation avec le premier mode de réalisation. Les différences sont décrites ci-dessous.For the second embodiment of the container device, the mounting operations for assembling the reinforcing devices 13 in the tray 12 differ little from the operations described in connection with the first embodiment. The differences are described below.

En tout début de montage, comme représenté à la figure 13, il s'agit de conformer les parois longitudinales et les parois transversales, ces dernières embarquant leur pan de trottoir 30, leur pan intermédiaire 37 et leur pan de fixation 39.At the very beginning of assembly, as shown in figure 13 it is a matter of conforming the longitudinal walls and the transverse walls, the latter loading their sidewalk 30, their intermediate section 37 and their attachment section 39.

La figure 14 correspond à la figure 5 et à la figure 10 pour replier à conformation le pan de trottoir 30 par pivotement le long de l'arrête supérieure de la paroi transversale 12T correspondante. Le pan intermédiaire 37 et le pan de fixation 39 sont aussi repliés par pivotement suivant des axes horizontaux de pliage.The figure 14 corresponds to the figure 5 and at the figure 10 to conformally fold the sidewalk 30 by pivoting along the upper edge of the corresponding transverse wall 12T. The intermediate section 37 and the attachment section 39 are also folded by pivoting along horizontal axes of folding.

Comme représenté à la figure 15, les pans de trottoir 30 sont rabattus pour être à l'horizontal du côté de l'intérieur du plateau. Le pan intermédiaire 37 est incliné sous le pan de trottoir 30, comme dans les cas expliqués précédemment. Le pan de fixation 39 est collé sur la face intérieure de la paroi transversale 12T correspondante, en s'étendant vers le bas, en direction du fond 12D du plateau.As represented in figure 15 , the sidewalls 30 are folded to be horizontal of the side of the inside of the board. The intermediate section 37 is inclined under the sidewalk 30, as in the cases explained above. The attachment panel 39 is glued on the inner face of the corresponding transverse wall 12T, extending downward, towards the bottom 12D of the plate.

En autre variante représentée à la figure 16, par rapport au premier mode de réalisation, le pan de fixation 39 est encore collé sur la face intérieure du pan principal 33, mais il s'étend vers le haut, sous la racine du pan de trottoir.In another variant shown in figure 16 , relative to the first embodiment, the attachment panel 39 is still bonded to the inner face of the main panel 33, but it extends upwardly, under the root of the sidewalk.

Dans cette variante, le pan de trottoir 30, le pan intermédiaire 37 et le pan de fixation 39 sont repliés à conformation avant que les parois transversales et les parois longitudinales ne soient repliées à conformation.In this variant, the sidewalk 30, the intermediate section 37 and the attachment panel 39 are folded to conformation before the transverse walls and the longitudinal walls are folded to conformation.

En variante non représentée sur la base du deuxième mode de réalisation, le pan de trottoir 30, le pan intermédiaire 37 et le pan de fixation 39 sont rattachés directement à la paroi transversale 12T correspondante mais le pan de fixation est replié à fixation vers le haut plutôt que vers le bas.In a variant not shown on the basis of the second embodiment, the sidewalk 30, the intermediate section 37 and the attachment section 39 are attached directly to the corresponding transverse wall 12T, but the attachment section is folded upwardly. rather than down.

Plus généralement, les murs latéraux externes peuvent avoir un sommet horizontal, situé au-dessous du niveau du haut des panneaux intérieurs participant à la détermination de la tranche supérieure du plateau.More generally, the outer side walls may have a horizontal vertex, located below the level of the top of the interior panels involved in determining the upper edge of the tray.

Les avantages de solidité et de facilité de mise en oeuvre du dispositif conteneur sont sensiblement les mêmes pour les différents modes de réalisation.The advantages of strength and ease of implementation of the container device are substantially the same for the various embodiments.

En variante non représentée, les tenons supérieurs de calage de gerbage sont disposés différemment, par exemple en étant au nombre de deux en haut des parois transversales. Les aménagements sur les encoches et échancrures sont en concordance.In a variant that is not shown, the upper stacking wedge lugs are arranged differently, for example by being two in number at the top of the transverse walls. The arrangements on the notches and notches are in agreement.
