- each post of a post is parallel to the adjacent lateral side of the triangular interface area, so that it can be applied against the interface area of an identical upper tray within a stack.
- the two opposite shorter side walls each comprise a cutout made in the lower part of the wall, the wall portion disposed above the cutout serving as a gripping strip for a user.
- the gripping strip of each short wall comprises a double thickness of blank, and is derived from the folding on itself of the forming flap of said side wall, which comprises a double fold line and the two parts of which extending on either side of this double line are provided with gripping cutouts, in match each other when this flap and folded on itself.
- the cut is formed from the lower edge of the short wall.
- the two opposite side walls the longest of the plate are provided with second tenons extending in the plane of these longest walls, and complementary notches made at the base of each tenon within the side wall and bottom wall.
- the longest walls include on their length, openings of visibility and ventilation of the products.

- 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.
- the plate is characterized in that the lateral flaps are associated with the main flaps which constitute the longer walls of the plate.
- Figure 1 is a perspective view in perspective of the corrugated cardboard blank of a transport tray and presentation according to a first embodiment of the invention
- Figures 2 and 3 are perspective views of two successive phases of the establishment of a tray according to the invention partially raised from the blank of Figure 1;
- FIG. 4 is a perspective view of the plate made according to the two phases of FIGS. 2 and 3, in the finished state,
- Figure 6 shows the carton blank from which the tray of Figure 5 is made
- FIGS 7 to 9 show the folding steps of the blank of Figure 6 to obtain the plate of Figure 5.
- a tray 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 bottom wall 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 folding lines.
- Each of the two shorter walls 3, 5 comprises two stacking pins 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.
- Figures 2 and 3 show at each angle 14 a particular configuration.
- the bottom wall 1 is rounded at 15 and the two side walls which join in this interface zone 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 bottom portion 15.
- the base 18 is cut from the bottom wall and connects the two opposite points of beginning of the rounding which covers an angle of substantially 45 °.
- 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.
- 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 plateau and whose lateral lines are inclined fold lines 19 and 20.
- 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.
- 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.
- the portion of each flap 27 defined by the edges 33 and 34 constitutes a stacking pin 7 of a raised plate.
- 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.
- 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 Wall 3.
- the side of the flap 27, delimited by the edges 33 and 34, projects well from the upper edge 36 of the corresponding lateral wall. 3, 5 thereby forming the stacking post 7 without protruding beyond the rectangular outline of the starting blank.
- each flap 22 is cut accordingly so that a recess 38 is created in the blank around the rounding 15 of the corner area 14 of the wall. background 1.
- each cutout 40, 41 is, in the tray established substantially vertically below a tenon 7.
- 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.
- 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 configuration substantially triangular angles of the tray and the rounded shape at these locations of the bottom wall is also advantageous when packing trays stacks by a plastic film packaging, surrounding the stack.
- the trays can be made according to conventional techniques of cutting, folding and gluing, with existing standard machines.
- the alternative embodiment of the tray according to the invention shown in Figures 5 to 9 is the same general concept of a plate provided with a bottom wall 1, and side walls 2 to 5 fixed to each other by the intermediate of a triangular interface area 16 whose tip 17 is oriented towards the edges 31, 32 of the side walls between which this zone 16 is interposed, and whose base 18 rests on the bottom wall 1.
- the plate according to this second variant has many similarities with that of the first variant, giving them both improved vertical compressive strength, particularly because of the geometry and the location of the interface areas 16 of the plateau .
- interface areas 16 extend indeed to the four corners of the plate and their triangular shape, of which the base 18 is supported on the bottom wall 16 and the tip 17 extends at the junction of two consecutive side walls 4 and 5, allows the two walls that surround it to define in their upper part, a right angle, which has the effect, when considered in combination with the base 18 in abutment on the bottom wall, to oppose the vertical compression exerted by the upper plates within a stack.
- the interface zone 16 is inclined with respect to the bottom wall, not 90 ° as are the lateral walls 2 to 5, but at a greater angle so that this triangular zone diverges from its base 18 to the tip 17, outside the contour defined by the bottom wall 1, while the surrounding side walls 4, 5 are substantially perpendicular to this bottom wall 1.
- This inclination is advantageously used to provide at each interface area, a stacking post, which is the major difference with the plate according to the first embodiment which provided that the tenon extends on a side wall of the tray .
- This beveled cut 53 makes it possible to release a space directly above the tip 17 of the inclined interface zone 16, within which the tenon of an identical lower plate can extend.
- This pin 54 also has a particular shape because it is arranged at the level of the zone interface 16 and thus in the angle formed by two consecutive walls 4 and 5 in Figure 5.
- the post 54 consists of two perpendicular sides 56 and 57, of a height of about 7 mm and a width of 1 cm each, which extend respectively in the extension of the side walls 4 and 5. and join at the tip 17 of the interface area.
- Each panel 56, 57 has a beveled side edge 58 which is parallel to the adjacent hinge edge 19, 20 of the interface area 16, so that the side edges 58 of the stud 54 of a lower plate come both to contact beveled edge 53 of the bottom wall 1 of the upper plate, and the interface area 16 of the upper plate.
- each tenon 54 of a plate retains by its inclined faces 58, the bevelled edges 53 and the interface areas 16 of an upper plate, in two directions at a time.
- the longest walls 2 and 4 of a plate are provided with central tenons 60 which extend in the plane of these walls 2 and 4 over a width of 20 cm. about 5 cm, and at the base of which are provided complementary notches 61 made at the junction between the relevant side wall 2, 4 and the bottom wall 1.
- the shorter walls 3 and 5 are provided with cutouts 64 of substantially rectangular shape and which are made from the lower edge of the side wall concerned 3, 5 and beyond.
- a gripping strip 66 for a user constituted by the portion of the flap not recessed. The user can thus apply the palm of his hand against the edge 32 of each short wall 3, 5 and slide his fingers within the underlying cutout 64 to seize the plate.
- each short wall 3, 5 has a double thickness of blank, resulting from the folding on itself of a double side flap.
- This flap comprises a double fold line 68 separating it into two half-shutters articulated to each other, and the one closest to the bottom wall 1 is articulated thereto, and comprises the above-mentioned cutout 64, then that the half-flap farthest from the bottom wall 1 comprises along its free edge 69 opposite the bottom wall, a recess of rectangular shape 70 complementary to the shape of the cutout 64.
- the recess 70 matches the contour of the cutout 64 and the gripping strip 66 has a double thickness of cardboard.
- the upper edge of the cutout 66 must be separated from the upper edge 32 of the wall 3, 5 by a distance low enough for the user's fingers to reach the rectangular cutouts 64 while his palm is resting on the edge 32.
- orifices 71 aeration and visibility of the product can be provided on the long walls 2, 4 and along them.
- Figures 5 to 9 show substantially circular orifices, but for longer walls of greater height, these holes may take the form of an oblong slot extending in a vertical direction.
- the plate according to this second embodiment is obtained from a blank of cardboard as shown in FIG. 6 provided with a central part intended to form the bottom wall 1, of two long flaps 25 articulated on the long sides of the bottom wall.
- Each long flap 25 is furthermore framed beyond each of its lateral edges by an interface zone 16 and a lateral fastening flap 27.
- the width t.3 of the long flap 25 is substantially equal to that of the side flap 27, and the height h 4 of the interface zone 16 is greater than the width t 3 of the long flap 25 and fastening flap 27 so that the blank portion extending on either side of the tip 17 of this interface area can act as tenon.
- the plate according to the second embodiment of the invention has four tenons arranged at reinforced locations of the plate, that is to say at the corners of the plate and supported by triangular zones of interface that enhance the vertical compressive strength of the tray.
