Description

« Plateau de transport et de présentation d'articles, tels que des pots de yaourt »  "Tray for transporting and presenting items, such as yoghurt pots"
L' invention concerne un plateau de transport et de présentation d'articles tels que des pots de yaourt, du type comprenant une paroi de fond et quatre parois latérales articulées à la paroi de fond et repliées vers le haut de façon à s'étendre dans un plan sensiblement perpendiculaire à la paroi de fond, et au moins un tenon de gerbage s' étendant vers le haut dans le prolongement d'une paroi latérale, le plateau étant obtenu par pliage à partir d'un flan notamment en carton ondulé de forme sensiblement rectangulaire. The invention relates to a tray for transporting and presenting articles such as yoghurt pots, of the type comprising a bottom wall and four side walls hinged to the bottom wall and folded upwards so as to extend into a plane substantially perpendicular to the bottom wall, and at least one stacking pin extending upwardly in the extension of a side wall, the plate being obtained by folding from a blank including shaped corrugated cardboard substantially rectangular.
On connaît déjà des plateaux de ce type, de forme générale rectangulaire, qui comporte deux tenons de gerbage sur chacune des deux parois parallèles opposées plus courtes.  Trays of this type, of rectangular general shape, are already known, which has two stacking lugs on each of the two opposite shorter parallel walls.
Ces plateaux présentent l'inconvénient que les quatre tenons font saillis au-delà du contour rectangulaire du flan de départ, ce qui constitue une perte de matière de carton de par exemple 5%.  These plates have the disadvantage that the four pins protrude beyond the rectangular contour of the starting blank, which is a loss of cardboard material of for example 5%.
L'invention a pour but de pallier cet inconvénient. Pour atteindre ce but, un plateau selon l'invention est caractérisé en ce que les parties du flan destinées à former les tenons sont comprises dans le contour rectangulaire du flan, déterminant la hauteur des parois latérales du plateau.  The invention aims to overcome this disadvantage. To achieve this purpose, a tray according to the invention is characterized in that the parts of the blank intended to form the tenons are included in the rectangular contour of the blank, determining the height of the side walls of the tray.
Selon une caractéristique avantageuse de l'invention, un tenon de gerbage est formé sur un volet de paroi latérale qui comporte une portion de paroi inférieure articulée à la paroi de fond par une ligne de pliage décalée en translation par rapport au plan de la paroi latérale, en direction du centre de la paroi de fond, et une portion de paroi supérieure qui est articulée à la portion de façon à s'étendre dans le plan de la paroi latérale lorsque le plateau est constitué, la portion de paroi étant alors inclinée par rapport à ce plan . According to an advantageous characteristic of the invention, a stacking post is formed on a side wall flap which comprises a lower wall portion hinged to the bottom wall by a fold line offset in translation relative to the plane of the side wall. in the direction of the center of the bottom wall, and an upper wall portion which is articulated to the portion so as to extend in the plane of the side wall when the plate is formed, the wall portion then being inclined relative to this plane.
Selon une autre caractéristique de l'invention, la partie de paroi formant le tenon comporte à sa base une découpe à travers laquelle s'étend la paroi de fond en formant une languette de butée latérale du tenon de gerbage d'un plateau inférieur dans une pile de plateau superposée . According to another characteristic of the invention, the wall portion forming the post comprises at its base a cutout through which the bottom wall extends by forming a lateral stop tab of the stacking post of a lower plate in a stack of stacked tray.
L'invention sera mieux comprise, et d'autres buts, caractéristiques, détails et avantages de celle-ci apparaîtront plus clairement dans la description explicative qui va suivre faite en référence aux dessins schématiques annexés donnés uniquement à titre d'exemple illustrant un mode de réalisation de l'invention et dans lesquels :  The invention will be better understood, and other objects, features, details and advantages thereof will appear more clearly in the explanatory description which follows, with reference to the appended schematic drawings given solely by way of example, illustrating a mode of embodiment of the invention and in which:
D'autres caractéristiques et avantages de l'invention ressortiront clairement de la description qui en est faite ci-après, à titre indicatif et nullement limitatif, en référence aux dessins annexés dans lesquels :  Other characteristics and advantages of the invention will emerge clearly from the description which is given hereinafter, by way of indication and in no way limiting, with reference to the appended drawings in which:
- la figure 1 est une vue en perspective d'une pile superposée de trois plateaux selon l'invention  FIG. 1 is a perspective view of a pile stacked with three trays according to the invention;
- la figure 2 est une vue en perspective d'un seul plateau selon l'invention ;  FIG. 2 is a perspective view of a single plate according to the invention;
- la figure 3 est une vue de dessus d'un flan en carton ondulé à partir duquel le plateau selon la figure 2 a été obtenu par pliage ;  - Figure 3 is a top view of a corrugated cardboard blank from which the tray according to Figure 2 has been obtained by folding;
- les figures 4 à 6 sont trois vues en perspective, illustrant trois phases différentes du processus d'établissement d'un plateau selon l'invention.  - Figures 4 to 6 are three perspective views illustrating three different phases of the process of establishing a tray according to the invention.
La figure 1 montre une pile de trois plateaux 1 en carton ondulé, selon l'invention, montés les uns sur les autres. L'empilage se fait à l'aide de moyens de tenons de gerbage comme il sera décrit ci-après.  Figure 1 shows a stack of three trays 1 of corrugated cardboard, according to the invention, mounted on each other. The stacking is done using means of stacking pins as will be described below.
La figure 2 montre un plateau 1 de la pile de la figure 1. Ce plateau comporte essentiellement une paroi de fond rectangulaire 3 et quatre parois latérales, à savoir deux parois parallèles et opposées plus longues 4 et deux parois parallèles et opposées plus courtes 7, qui sont articulés à la paroi de fond et formés par pliage de façon à s'étendre dans un plan perpendiculaire au plan de la paroi de fond. Comme le montre la figure, les deux parois latérales plus longues 4 sont pourvues chacune d'un tenon de gerbage 8 formé par une partie relativement large de la paroi en saillie du bord supérieur 9 de la paroi. FIG. 2 shows a plate 1 of the battery of FIG. 1. This plate essentially comprises a wall of rectangular bottom 3 and four side walls, namely two longer parallel and opposite walls 4 and two shorter parallel and opposite walls 7, which are articulated to the bottom wall and formed by folding so as to extend in a plane perpendicular to the plane of the bottom wall. As shown in the figure, the two longer side walls 4 are each provided with a stacking lug 8 formed by a relatively large portion of the wall projecting from the upper edge 9 of the wall.
Le plateau 1 selon l'invention est obtenu par pliage d'un flan d'origine en carton ondulé, tel que représenté à la figure 3. La particularité essentielle de l'invention réside dans le fait que le plateau 1 comporte des tenons de gerbage 8 en saillis au-dessus du bord supérieur du plateau, formé par les bords supérieurs des différentes parois sans que la réalisation des tenons implique une perte de matière de carton ondulé. Cet effet spécifique de l'invention est obtenu grâce à une configuration particulière des parois porteuses des tenons .  The tray 1 according to the invention is obtained by folding a blank of corrugated cardboard, as shown in Figure 3. The essential feature of the invention lies in the fact that the tray 1 has stacking lugs 8 protruding above the upper edge of the tray, formed by the upper edges of the different walls without the realization of the tenons involves a loss of corrugated cardboard material. This specific effect of the invention is obtained thanks to a particular configuration of the bearing walls of the tenons.
Chaque paroi latérale 4, 7 est formée essentiellement par un volet numéroté également 4 ou 7, qui est articulé à la paroi de fond 3 le long d'une ligne de pliage autour de laquelle le volet peut être amené à pivoter de sa position dans la plan du flan vers sa position redressée, perpendiculaire au fond. Les lignes de pliage des deux parois parallèles opposées plus courtes 7 sont notées 11.  Each side wall 4, 7 is formed essentially by a shutter numbered also 4 or 7, which is articulated to the bottom wall 3 along a fold line around which the flap can be pivoted from its position in the plane of the blank to its upright position, perpendicular to the bottom. The fold lines of the two opposite shorter parallel walls 7 are denoted 11.
Chaque volet 7 est prolongé à chaque côté par une partie latérale qui forme un volet 13 qui est articulée au bord latéral du volet 7. La ligne d'articulation constitue une ligne de pliage 14 permettant au volet 13 de pivoter lors du redressement du volet 7, dans sa position de paroi latérale perpendiculaire au fond 3 dans le plan de la paroi latérale adjacente 4 en prenant appui sur la partie périphérique correspondante 16 de la paroi de fond. Pour permettre ce pivotement, le volet 13 est découpé du volet adjacent 4 par une ligne de découpe 18. Each flap 7 is extended at each side by a lateral portion which forms a flap 13 which is articulated to the lateral edge of the flap 7. The hinge line constitutes a fold line 14 allowing the flap 13 to pivot during the straightening of the flap 7 in its lateral wall position perpendicular to the bottom 3 in the plane of the adjacent lateral wall 4 while bearing on the corresponding peripheral part 16 of the wall background. To enable this pivoting, the flap 13 is cut off from the adjacent flap 4 by a cutting line 18.
La particularité essentielle de l'invention réside dans la configuration des volets et parois latérales plus longs 4.  The essential feature of the invention lies in the configuration of the flaps and longer side walls 4.
Dans l'exemple représenté, chaque volet 4 comporte deux portions, une portion plus étroite médiane 20 qui est articulée par une ligne de pliage 22 à la paroi de fond 3 et une portion 24 qui constitue le restant du volet 4. Cette portion restante est articulée à la portion 20 par une ligne de pliage 26 qui s'étend parallèlement à la ligne de pliage 22, sensiblement à la mi-hauteur du volet 4, tout en étant découpée à sa base du fond 1 des deux côtés de la portion 20 le long des lignes 21. Dans ces zones de découpe, la paroi de fond représente donc une partie de bord libre 28.  In the example shown, each flap 4 comprises two portions, a median narrower portion 20 which is articulated by a fold line 22 to the bottom wall 3 and a portion 24 which constitutes the remainder of the flap 4. This remaining portion is articulated to the portion 20 by a fold line 26 which extends parallel to the fold line 22, substantially at the mid-height of the flap 4, while being cut at its bottom base 1 on both sides of the portion 20 along these lines 21. In these cutting zones, the bottom wall thus represents a free edge portion 28.
Comme le montrent les figures, la ligne d'articulation et de pliage 22 de chaque portion de volet 20 est décalée en translation du bord 28 de la paroi de fond en direction de la ligne médiane parallèle à ce bord, de cette paroi de fond. Ce décalage est indiqué sur la figure 3 par la référence a. C'est sur cette distance que la paroi de fond 3 est découpée à partir de la ligne de découpe 21.  As shown in the figures, the line of articulation and folding 22 of each flap portion 20 is shifted in translation from the edge 28 of the bottom wall towards the center line parallel to this edge, of this bottom wall. This offset is indicated in FIG. 3 by the reference a. It is at this distance that the bottom wall 3 is cut from the cutting line 21.
Par conséquent le volet de paroi 4 est pivotant dans son ensemble autour de la ligne de pliage 22, tandis que la partie de volet 24 est pivotant par rapport à la portion de volet 20 autour de la ligne 26.  As a result, the wall flap 4 is pivoted as a whole around the fold line 22, while the flap portion 24 is pivotable with respect to the flap portion 20 around the line 26.
C'est grâce au décalage de la ligne de pliage 22 que la partie de paroi 8 qui constitue un tenon de gerbage lorsque le plateau est constitué peut se situer au-dessus du bord supérieur du plateau, déterminé par des parois latérales 7. Comme le montre clairement la figure 2, c'est aussi le bord 31 des volets 4 de part et d'autre de la portion de tenon 8 avec son bord 32 qui, après le relèvement du volet, revient au niveau du bord supérieur 30 des parois 7 et donc du plateau. Par conséquent, par rapport aux plateaux dans lesquels les volets de paroi latérale 4 sont articulés au bord correspondant de la paroi de fond, le décalage des lignes d'articulation et de pliage 22, selon la distance a permet d'obtenir un rehaussement du bord extérieur libre 32 de la partie de volet 20 par rapport au bord 30. Sans ce décalage, le bord 32 serait au même niveau que le bord 30. Ainsi l'invention apporte une réduction de chute et ainsi une économie en matière de carton ondulé puisque sans le décalage des lignes de pliage, il aurait fallu prévoir des parties en saillies spécifiques au-delà du bord 32 du flan de la figure 3. It is thanks to the offset of the folding line 22 that the wall part 8 which constitutes a stacking post when the plate is formed can be situated above the upper edge of the plate, determined by lateral walls 7. As shown in FIG. clearly shows Figure 2, it is also the edge 31 of the flaps 4 on either side of the tenon portion 8 with its edge 32 which, after the raising of the flap, returns to the upper edge 30 of the walls 7 and therefore the plateau. Therefore, compared to trays in which the side wall flaps 4 are hinged to the corresponding edge of the bottom wall, the offset of the hinge lines and folding 22, according to the distance a allows to obtain an edge enhancement outer free 32 of the flap portion 20 with respect to the edge 30. Without this offset, the edge 32 would be at the same level as the edge 30. Thus the invention provides a reduction of fall and thus a saving in corrugated cardboard since without the shifting of the fold lines, it would have been necessary to provide specific protruding parts beyond the edge 32 of the blank of FIG.
Dans l'exemple représenté aux figures, la longueur des parties de tenons 8 et la longueur c des volets 13 est choisie de façon que les bords extérieurs 34 des volets viennent en appui contre les bords verticaux et latéraux 36 des portions de paroi latérales 20 redressées, pour augmenter la rigidité du plateau.  In the example shown in the figures, the length of the tenon portions 8 and the length c of the flaps 13 is chosen so that the outer edges 34 of the flaps abut against the vertical and lateral edges 36 of the sidewall portions 20 rectified , to increase the rigidity of the plate.
Afin de faciliter les opérations de pivotement des volets lors de la constitution des plateaux, il est avantageux de donner aux volets 13 la forme légèrement inclinée qui ressort de la figure 3 du flan de départ.  In order to facilitate the pivoting operations of the flaps during the formation of the trays, it is advantageous to give the flaps 13 the slightly inclined shape that emerges from FIG. 3 of the initial blank.
Sur cette figure on constate encore dans la partie de volet 20 des découpes 37 à partir de la ligne de pliage 22 qui créent des encoches 38 formant dans la paroi relevée des ouvertures d'aération du plateau. De telles ouvertures, notées 39, sont également découpées dans les volets de paroi 7.  In this figure is still found in the flap portion 20 of the cutouts 37 from the fold line 22 which create notches 38 forming in the raised wall vent openings of the tray. Such openings, denoted 39, are also cut in the wall shutters 7.
Les découpes 37 dans la portion 20 ont pour effet que le bord de la paroi de fond soit libre sur la largeur de l'encoche. La portion de bord libre porte la référence 40. En découpant les encoches 38 de façon que les lignes de coupe 39 tout en restant parallèles aux parties de bord libre 28 du fond 1, soit un peu décalées vers l'intérieur de la paroi de fond, sensiblement d'une distance correspondant à l'épaisseur du carton, on obtient que le bord 39 puisse agir comme butée latérale, en coopération avec un tenon 8 d'un plateau disposé dans une pile en-dessus, lors d'un empilage de carton selon la figure 1. Ainsi, on crée des pattes de butée latérales 41. The cutouts 37 in the portion 20 have the effect that the edge of the bottom wall is free on the width of the notch. The free edge portion carries the reference 40. By cutting the notches 38 so that the cutting lines 39 while remaining parallel to the free edge portions 28 of the bottom 1, is slightly offset towards the inside of the bottom wall , substantially a distance corresponding to the thickness of the carton, it is obtained that the edge 39 can act as a lateral stop, in cooperation with a pin 8 of a tray disposed in a pile above, during a stack of cardboard according to Figure 1. Thus, it creates lateral abutment lugs 41.
Dans cette pile, le tenon vient latéralement en appui contre les pattes de butée 40 tandis que son bord supérieur est en appui sous la partie périphérique de la paroi de fond du plateau au-dessus. Il est encore à noter que la ligne de pliage 11 des volets 13 est légèrement en retrait en direction de la ligne médiane du plateau pour que ces volets puissent prendre appui sur la partie périphérique 16 de la paroi de fond.  In this stack, the tenon laterally bears against the abutment lugs 40 while its upper edge is supported under the peripheral portion of the bottom wall of the tray above. It should also be noted that the fold line 11 of the flaps 13 is slightly set back towards the median line of the tray so that these flaps can bear on the peripheral portion 16 of the bottom wall.
Concernant l'établissement d'un plateau selon l'invention, par pliage des différents volets 4 et 7 à partir du flan de la figure 3, il est illustré par les figures 4 à 6. On fait d'abord pivoter les volets de paroi latérale 7 autour de leur ligne de pliage 11 dans leur position verticale, c'est-à-dire perpendiculaire à la paroi de fond et ensuite les volets latéraux 13 de chaque volet 7 autour de leur ligne de pliage 14 dans leur position perpendiculaire à la paroi latérale et en appui sur la portion périphérique 16 de la paroi de fond 3. Dans la prochaine opération illustrée par la figure 6, on fait pivoter chaque volet de paroi latérale 4 autour de la ligne de pliage 22 de la portion de volet 20 jusqu'à ce que la partie restante de la paroi soit située dans le plan vertical de la paroi latérale, avec les parties latérales en appui contre les faces extérieures des volets 13. La fixation de ces parties de paroi en contact est effectuée par collage, la colle ayant été appliquée auparavant.  Regarding the establishment of a tray according to the invention, by folding the various flaps 4 and 7 from the blank of Figure 3, it is illustrated in Figures 4 to 6. It is first pivoted the wall flaps 7 around their fold line 11 in their vertical position, that is to say perpendicular to the bottom wall and then the lateral flaps 13 of each flap 7 around their fold line 14 in their position perpendicular to the side wall and bearing on the peripheral portion 16 of the bottom wall 3. In the next operation illustrated in Figure 6, is rotated each side wall flap 4 around the fold line 22 of the flap portion 20 until the remaining part of the wall is situated in the vertical plane of the side wall, with the lateral parts bearing against the outer faces of the flaps 13. The attachment of these wall parts in contact is effected by gluing, the glue having been applied before.
En se reportant à la figure 2, qui montre le plateau fini, on constate qu'en raison du décalage de la distance a, la portion de volet de paroi latérale 20 est inclinée par rapport à la paroi de fond 3 et que la partie restante 24 du volet a effectué un mouvement de pivotement autour de la ligne de pliage 26 pour venir dans sa position verticale par rapport à la paroi de fond 3. Referring to FIG. 2, which shows the finished plate, it can be seen that due to the offset of the distance a, the sidewall flap portion 20 is inclined with respect to the bottom wall 3 and that the remaining portion 24 of the shutter has made a pivoting movement around the fold line 26 to come in its vertical position relative to the bottom wall 3.
Bien entendu de multiples modifications peuvent être apportées au plateau tel qu'il vient d'être décrit à titre d'exemple, en se référant aux figures. Ainsi la largeur des tenons de gerbage 8 peut être réalisée autrement et plusieurs tenons pourraient être prévus sur chaque paroi. On pourrait également envisager de prévoir les tenons sur les parois latérales plus courtes 7 sans sortir du cadre de l'invention.  Of course, many modifications can be made to the plate as just described by way of example, with reference to the figures. Thus the width of the stacking lugs 8 can be made differently and several lugs could be provided on each wall. One could also consider providing the tenons on the shorter side walls 7 without departing from the scope of the invention.
