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 des parois latérales qui sont articulées à la paroi de fond et repliées vers le haut selon un angle sensiblement droit et au moins un tenon d'empilage s' étendant vers le haut dans le prolongement du plan d'une paroi latérale, le plateau étant obtenu par pliage à partir d'un seul flan en carton ondulé de forme rectangulaire. The invention relates to a tray for transporting and presenting articles such as yoghurt pots, of the type comprising a bottom wall and side walls which are articulated to the bottom wall and folded upwards at a substantially right angle. and at least one stacking post extending upwardly in the extension of the plane of a side wall, the tray being obtained by folding from a single rectangular corrugated cardboard blank.
On connaît déjà des plateaux de ce type, de forme générale rectangulaire, qui comportent deux tenons sur chacune des deux parois opposées plus courtes.  Trays of this type, of a generally rectangular shape, which have two tenons on each of the two shorter, shorter walls, are already known.
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 par exemple 5% de matière de carton ondulé.  These plates have the disadvantage that the four pins protrude beyond the rectangular contour of the starting blank, which is a loss of for example 5% of corrugated cardboard material.
L'invention a pour but de pallier cet inconvénient. The invention aims to overcome this disadvantage.
Pour atteindre ce but, un plateau selon l'invention est caractérisé en ce qu' il présente un contour rectangulaire et en ce que les parties formant les tenons sont comprises dans ce contour. To achieve this purpose, a tray according to the invention is characterized in that it has a rectangular contour and in that the parts forming the tenons are included in this contour.
Selon une caractéristique de l'invention, le plateau est caractérisé en ce que le tenon est formé sur un volet latéral d'un volet principal de formation d'une paroi latérale, qui est articulée au volet principal par un zone d' interface de façon à pouvoir pivoter dans une position perpendiculaire au volet principal et de fixation sur le volet de paroi adjacente redressé, que l'arête interne découpée du volet latéral est incliné par rapport à la ligne de pliage du volet principal de façon que la hauteur du volet latéral soit supérieure à son extrémité à la hauteur dans sa zone d' interface et en ce que cette zone d' interface comporte un dispositif de lignes de pliage qui assurent que cette arête soit parallèle à la paroi de fond lorsque le volet latéral est dans sa position de fixation précitée. According to one characteristic of the invention, the plate is characterized in that the tenon is formed on a lateral flap of a main flap for forming a side wall, which is articulated to the main flap by an interface zone so as to able to pivot in a position perpendicular to the main and fastening flap on the rectified adjacent wall flap, that the cut-out inner edge of the lateral flap is inclined with respect to the fold line of the main flap so that the height of the lateral flap is greater than its end at the height in its interface area and in that this interface area has a folding line device which ensures that this edge is parallel to the bottom wall when the side flap is in its aforementioned fixing position.
Selon une autre caractéristique de l'invention le plateau est caractérisé en ce que la zone d' interface est en forme d'un triangle dont la pointe est située au niveau de l'arête supérieure libre des volets et dont la base est découpée dans le flan et adjacente à la paroi de fond et en ce que les côtés latéraux du triangle constituent des lignes de pliage.  According to another characteristic of the invention, the plate is characterized in that the interface zone is in the form of a triangle whose point is located at the level of the free top edge of the flaps and whose base is cut in the flan and adjacent to the bottom wall and in that the lateral sides of the triangle constitute fold lines.
Selon encore une autre caractéristique de l'invention, le plateau est caractérisé en ce que la paroi de fond est découpée et arrondie dans la zone d'interface précitée.  According to yet another characteristic of the invention, the plate is characterized in that the bottom wall is cut and rounded in the aforementioned interface zone.
Selon encore une autre caractéristique de l'invention, le plateau est caractérisé en ce que, dans le flan, le bord extérieur supérieur du volet latéral comporte au niveau de son extrémité une partie dans laquelle ce bord est en alignement avec le bord supérieur du volet principal, tandis que le bord supérieur dans sa partie restante est incliné et parallèle au bord inférieur du volet et en ce que, lorsque le volet est dans sa position relevée de fixation précitée, la partie de bord est sensiblement en alignement avec le bord extérieur des volets de paroi redressées, la portion de bord supérieur constituant le tenon d'empilage.  According to yet another characteristic of the invention, the plate is characterized in that, in the blank, the upper outer edge of the lateral flap comprises at its end a portion in which this edge is in alignment with the upper edge of the shutter. main, while the upper edge in its remaining part is inclined and parallel to the lower edge of the flap and in that, when the flap is in its raised position of aforementioned fixing, the edge portion is substantially in alignment with the outer edge of the wall flaps rectified, the upper edge portion constituting the stacking post.
Selon encore une autre caractéristique de l'invention, le plateau est caractérisé en ce que le volet latéral comporte, découpée dans l'arête inférieure au moins une encoche, qui est située en-dessous de la portion du tenon et forme, avec une encoche dans le volet de paroi latérale adjacente et dans la portion périphérique de la paroi de fond, lorsque le plateau est constitué, un espace de réception du tenon d'un plateau inférieur dans une pile de plateaux.  According to yet another characteristic of the invention, the plate is characterized in that the lateral flap comprises, cut in the lower edge at least one notch, which is located below the portion of the tenon and forms, with a notch in the adjacent side wall flap and in the peripheral portion of the bottom wall, when the tray is formed, a receiving space of the tenon of a lower tray in a stack of trays.
Selon encore une autre caractéristique de l'invention, le plateau est caractérisé en ce que les volets latéraux sont associés aux volets principaux qui constituent les parois plus longues du plateau. According to yet another characteristic of the invention, the plate is characterized in that the Side flaps are associated with the main shutters that make up the longer walls of the plateau.
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 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, made with reference to the accompanying drawings given solely by way of example illustrating a mode of embodiment of the invention and in which:
la figure 1 est une vue à plat en perspective du flan de départ en carton ondulé d'un plateau de transport et de présentation selon 1 ' invention ;  Figure 1 is a perspective flat view of the corrugated cardboard starting blank of a transport tray and presentation according to the invention;
les figures 2 et 3 sont des vues en perspective de deux phases successives de l'établissement d'un plateau selon l'invention partiellement remontée ;  Figures 2 and 3 are perspective views of two successive phases of the establishment of a tray according to the invention partially raised;
la figure 4 est une vue en perspective de plateau selon l'invention à l'état fini.  Figure 4 is a perspective view of the tray according to the invention in the finished state.
En se référant à la figure 3, un plateau selon l'invention, comporte essentiellement une paroi de fond 1 d'une forme sensiblement rectangulaire et quatre parois latérales 2, 3, 4 et 5 qui s'étendent verticalement à partir de la paroi de fond 1, à savoir deux parois latérales parallèles, opposées 2 et 4 de plus grande longueur et deux parois opposées parallèles de plus faible longueur 3 et 5. Le plateau est réalisé par pliage d'un flan en carton ondulé d'une forme rectangulaire, avec des lignes de découpe et de pliage appropriées.  Referring to Figure 3, a tray according to the invention essentially comprises a bottom wall 1 of a substantially rectangular shape and four side walls 2, 3, 4 and 5 which extend vertically from the wall of bottom 1, namely two opposite parallel side walls 2 and 4 of greater length and two opposite parallel walls of shorter length 3 and 5. The plate is made by folding a corrugated cardboard blank of a rectangular shape, with appropriate cutting and bending lines.
Chacune des deux parois plus courtes 3, 5 comporte deux tenons d'empilage 7 disposés symétriquement par rapport à l'axe longitudinal médiane du plateau et, sensiblement verticalement en-dessous de chaque tenon 7, un évidement 9 permettant, lors de l'empilage de plusieurs plateaux la réception du tenon d'empilage 7 du plateau inférieur dans la pile ainsi formée.  Each of the two shorter walls 3, 5 comprises two stacking posts 7 arranged symmetrically with respect to the median longitudinal axis of the plate and, substantially vertically below each pin 7, a recess 9 allowing, during stacking several trays receiving the stacking post 7 of the lower plate in the stack thus formed.
Les figures 2 et 3 montrent au niveau de chaque angle 14 une configuration particulière. Au niveau de chacune de ces zones d'angle la paroi de fond 1 est arrondie en 15 et les deux parois latérales qui se joignent dans cette zone d'interface 16 forment un triangle dont la pointe 17 se trouve à la jonction des arêtes supérieures des parois et dont la base sensiblement rectiligne 18 est en regard de la partie arrondie de fond 15. La base 18 est découpée de la paroi de fond et relie les deux points opposés de début de l'arrondie qui couvre un angle de sensiblement 45°. Figures 2 and 3 show at each angle 14 a particular configuration. At each of these corner areas the bottom wall 1 is rounded at 15 and the two side walls that join in this interface area 16 form a triangle whose tip 17 is at the junction of the upper edges of the walls and whose substantially rectilinear base 18 is opposite the rounded portion of bottom 15. The base 18 is cut from the bottom wall and connects the two opposite points of beginning of the round which covers an angle of substantially 45 °.
C'est dû à cette forme particulière des angles 14 que les tenons d'empilage 7 s'inscrivent dans le contour rectangulaire du flan de départ 1 à partir duquel les parois latérales 2 à 4 sont obtenues par pliage.  It is due to this particular shape of the angles 14 that the stacking pegs 7 are part of the rectangular contour of the starting blank 1 from which the side walls 2 to 4 are obtained by folding.
Conformément aux figures, chaque paroi latérale plus courte 3, 5 est formée par un volet 22, qui est articulée à la paroi de fond 1 le long d'une ligne de pliage 23 et présente une largeur légèrement inférieure à la largeur de la paroi de fond 1.  According to the figures, each shorter side wall 3, 5 is formed by a flap 22, which is articulated to the bottom wall 1 along a fold line 23 and has a width slightly smaller than the width of the wall of the wall. background 1.
Les deux parois plus longues 2, 4 présentent une structure plus complexe et comportent chacune un volet principal 25 relié à la paroi de fond 1 par une ligne de pliage 26 et, à chaque côté de ce volet principal 25, un volet latéral 27 situé en face d'un bord latéral d'un volet 22 duquel il est séparé par une ligne de découpe spécifique 28. Chaque volet latéral 27 est relié au volet principal par une zone d'interface triangulaire qui, lorsque les parois sont remontées constitue la zone triangulaire 16 du plateau et dont les lignes latérales sont des lignes de pliage inclinées 19 et 20. Lors de l'établissement du plateau les volets 27 sont collés aux volets de paroi 22 de façon connue en soi.  The two longer walls 2, 4 have a more complex structure and each comprise a main flap 25 connected to the bottom wall 1 by a fold line 26 and, on each side of this main flap 25, a lateral flap 27 located in face of a side edge of a flap 22 from which it is separated by a specific cutting line 28. Each side flap 27 is connected to the main flap by a triangular interface area which, when the walls are raised is the triangular area 16 of the tray and whose lateral lines are inclined fold lines 19 and 20. During the establishment of the tray flaps 27 are glued to the wall flaps 22 in a manner known per se.
En se référant à la figure 1, on constate plus précisément que la ligne de découpe 28 de chaque volet latéral 27, le séparant du bord latéral adjacent d'un volet 22 est inclinée par rapport à la ligne de pliage 26 de son volet principal 25 de façon que le volet 27 présente à son extrémité libre 30 une hauteur hl qui est supérieure à la hauteur interne h2, c'est-à-dire de la partie triangulaire 16. Referring to FIG. 1, it can be seen more precisely that the cutting line 28 of each lateral flap 27 separating it from the adjacent lateral edge of a flap 22 is inclined with respect to the fold line 26 of its main flap. so that the flap 27 has at its free end 30 a height hl which is greater than the internal height h2, that is to say of the triangular portion 16.
On constate que l'arête extérieure 32 d'un volet 27, qui fait suite à l'arête extérieure 31 de son volet principal 25 est découpée de façon à s'étendre à partir du sommet de triangle 17 sensiblement parallèlement à la ligne de découpe 28 sur une longueur prédéterminée et se replace ensuite dans sa partie 33 jusqu'à l'arête extérieure perpendiculaire libre 30 dans l'alignement de l'arête extérieure 31 du volet principal 25. Les parties d'arêtes 32 et 33 sont donc jointes par une portion de ligne de découpe relativement courte 34. Comme le montrent les figures 2 et 3, la partie de chaque volet 27 délimitée par les arêtes 33 et 34 constitue un tenon d'empilage 7 d'un plateau remonté.  It is found that the outer edge 32 of a flap 27, which follows the outer edge 31 of its main flap 25 is cut so as to extend from the triangle vertex 17 substantially parallel to the cutting line. 28 on a predetermined length and then returns in its portion 33 to the outer perpendicular outer edge 30 in alignment with the outer edge 31 of the main flap 25. The edge portions 32 and 33 are therefore joined by a portion of relatively short cutting line 34. As shown in Figures 2 and 3, the portion of each flap 27 defined by the edges 33 and 34 constitutes a stacking pin 7 of a raised plate.
Les lignes de pliage 19 et 20 de chaque zone d'angles triangulaires 16 et leur angle d'inclinaison sont choisis de façon que, lors de la constitution des parois latérales, c'est-à-dire lors du pliage du volet principal 25 autour de sa ligne de pliage 26 et le pliage de chaque volet 27 le long des lignes 19 et 20, le bord ou l'arête 28 vient en appui sur la zone périphérique adjacente 35 du fond 1, comme on le voit sur la figure 2. Sur cette figure on constate que le bord extérieur libre 30 de chaque volet 27, dans sa position remontée verticale est incliné, tandis que le bord 32 s'étend parallèlement et au niveau du bord supérieur 31 de la paroi latérale 25 et du bord supérieur de la paroi latérale la plus courte 3, 5 adjacente qui a été remontée par pliage autour de la ligne de pliage 23. Par contre la partie du volet 27, délimitée par les bords 33 et 34 est bien en saillie du bord supérieur 36 de la paroi latérale correspondant 3, 5 en formant ainsi le tenon d'empilage 7 sans faire saillie au-delà du contour rectangulaire du flan de départ.  The fold lines 19 and 20 of each zone of triangular angles 16 and their angle of inclination are chosen so that, during the constitution of the side walls, that is to say during the folding of the main shutter 25 around of its folding line 26 and the folding of each flap 27 along the lines 19 and 20, the edge or edge 28 bears on the adjacent peripheral zone 35 of the bottom 1, as seen in FIG. 2. In this figure, it can be seen that the free outer edge 30 of each flap 27, in its vertical raised position, is inclined, while the edge 32 extends parallel to and at the level of the upper edge 31 of the lateral wall 25 and the upper edge of the shorter side wall 3, 5 adjacent which has been raised by folding around the fold line 23. By against the portion of the flap 27, defined by the edges 33 and 34 is projecting from the upper edge 36 of the wall corresponding side 3, 5 thus forming the tenon of e mpilage 7 without protruding beyond the rectangular outline of the starting blank.
Pour permettre le pivotement des volets 27, le bord latéral adjacent 37 de chaque volet 22 est découpé en conséquence de façon qu'un évidement 38 soit créé dans le flan autour de l'arrondie 15 de la zone d'angle 14 de la paroi de fond 1. To allow the flaps 27 to pivot, the adjacent lateral edge 37 of each flap 22 is cut into Accordingly, a recess 38 is created in the blank around the radius 15 of the corner area 14 of the bottom wall 1.
Concernant les découpes 9 de réception d'un tenon d'empilage d'un autre plateau, inférieur dans une pile, elle est formée par une découpe ovale 40 dans le bord 28 d'un volet 27 et 41 dans le volet adjacent 22. La découpe 41 s'étend jusque dans la zone périphérique 35 de la paroi de fond 1. Les découpes 40 et 41 sont disposées de façon qu'elles se superposent lorsque les parois sont remontées. La disposition de la découpe 40 est telle que sa ligne médiane perpendiculaire à l'arête 28 coupe sensiblement au milieu la partie formant le tenon 7. Ainsi chaque découpe 7 se trouve, dans le plateau établi sensiblement verticalement en-dessous d'un tenon.  Regarding the cutouts 9 for receiving a stacking post of another tray, lower in a stack, it is formed by an oval cutout 40 in the edge 28 of a flap 27 and 41 in the adjacent flap 22. The cutout 41 extends into the peripheral zone 35 of the bottom wall 1. The cutouts 40 and 41 are arranged so that they overlap when the walls are raised. The disposition of the cutout 40 is such that its median line perpendicular to the edge 28 substantially intersects in the middle the portion forming the pin 7. Thus each cutout 7 is in the tray established substantially vertically below a pin.
La description d'un plateau selon l'invention, qui vient d'être faite en se référant aux figures montre que l'invention présente de nombreux avantages. Tout d'abord elle assure une économie en carton ondulé dans la mesure où les parties du flan, qui sont destinées à constituer les tenons du plateau ne dépassent pas le contour avantageusement rectangulaire du flan. Pour assurer une bonne résistance mécanique des tenons, les cannelures du carton ondulé sont orientées dans les parois latérales dont font partis les tenons d'empilage dans le sens de compression, c'est-à-dire sensiblement dans le sens d'empilage des plateaux. La configuration sensiblement triangulaire des angles du plateau et la forme arrondie à ces endroits de la paroi de fond est aussi avantageux lors de l'emballage de piles de plateaux par un film en matière plastique d'emballage, entourant la pile.  The description of a tray according to the invention, which has just been made with reference to the figures shows that the invention has many advantages. Firstly it ensures a saving in corrugated cardboard insofar as the parts of the blank, which are intended to form the tenons of the tray do not exceed the advantageously rectangular contour of the blank. To ensure good mechanical strength of the tenons, the corrugated cardboard grooves are oriented in the side walls which the stacking tenons part in the direction of compression, that is to say substantially in the stacking direction of the trays. . The substantially triangular configuration of the corners of the tray and the rounded shape at these locations of the bottom wall is also advantageous when packaging trays stacks by a plastic packaging film surrounding the stack.
Très appréciable est également le fait que, malgré ces nombreux avantages, les plateaux peuvent être réalisés selon des techniques usuelles de découpe, de pliage et de collage, avec des machines standard existantes . Bien entendu de nombreuses modifications peuvent être apportées au plateau qui vient d'être décrit, à titre d'exemple, sans sortir du cadre de l'invention. Ainsi il est possible de prévoir les tenons sur les côtés longs du plateau. Il suffit à cette fin de prévoir les volets latéraux sur les volets plus courts portant la référence 3 et 5 sur les dessins. En modifiant les dimensions des configurations en triangle des angles du plateau, il est possible d'obtenir des tenons plus ou moins longs dans la direction de leur extension au-delà du bord supérieur du plateau. Very appreciable is also the fact that, despite these many advantages, the trays can be made according to conventional techniques of cutting, folding and gluing, with existing standard machines. Of course, many modifications can be made to the plateau that has just been described, for example, without departing from the scope of the invention. Thus it is possible to provide the tenons on the long sides of the plate. For this purpose it is sufficient to provide the lateral flaps on the shorter flaps with the reference 3 and 5 on the drawings. By modifying the dimensions of the triangle configurations of the angles of the plate, it is possible to obtain longer or shorter tenons in the direction of their extension beyond the upper edge of the plate.
