- the second flaps and / or first flaps each have a single tongue forming an angle, centered relative to the corresponding flap;
- At least one tongue forming an angle extends over a length greater than or equal to half, by example equal to two thirds of the length of the corresponding main wall.
- the width of the tab (s) is between the fifth and the tenth, for example of the order of one seventh of the length of the second or of the first corresponding flap.
- the tray has an octagonal section with cut corners, said cut corners being formed by intermediate walls located between the main walls.
- the invention also proposes a blank for the formation of a tray, comprising a rectangular central flap provided on each side with a rectangular main flap, namely two first main flaps opposite ears or with secondary flaps, and two second main flaps with secondary flaps, said ears or said secondary flaps being connected to the edge of said main flaps opposite the central flap, characterized in that the secondary flaps respectively connected to the two second main flaps each have at least one rectangular tongue precut over the entire transverse width of said secondary flap, said tongue being connected to the corresponding main flap by a fold line.
- said secondary flaps connected respectively to the second main flaps each have a single rectangular precut tab centered with respect to said corresponding secondary flap.
- the first two main flaps comprising ears, each ear extends above the main flap to which said ear is attached, then outwards, parallel to said main flap and over a distance equal to the width transverse of the adjacent main flap.
- Each ear may also include a second part connected to the first part, constituted in the manner just described, by a fold line and extending perpendicular to said first part towards the adjacent main flap over a distance for example equal to half the width of a main flap.
- the secondary flaps of the first main flaps each comprise at least one rectangular tongue precut over the entire transverse width of said secondary flap, said tongue being connected to the corresponding first main flap by a fold line.
- the two second main flaps further comprise two lateral end flaps located on either side, and connected by fold lines to the lateral sides of said second main flaps.
- FIG. 1 is a perspective view of a tray according to an embodiment of the invention.
- FIG. 1a is a perspective view of a tray according to another embodiment of the invention.
- FIG. 1 is a top view of the tray of Figure 1.
- FIG. 3 is a section view on a large scale of the tongue forming the angle iron of FIGS. 1, 1a and 2.
- FIG. 4 is a plan view of a blank according to an embodiment of the invention, making it possible in particular to obtain the tray of FIG. 1.
- FIG. 4a is a plan view of a blank according to another embodiment of the invention, to obtain the tray of Figure 1a.
- FIG. 5 is a schematic view showing the first stages of manufacturing a tray according to the invention with a blank according to Figure 4.
- Figures 1 and 2 show a parallelepipedal tray 1 open upwards, in corrugated sheet double-sided comprising a bottom 2 and a belt of main walls 3 provided with two opposite sidewalks 4 or four reinforced corner angles (not shown), for example having vertically two to three thicknesses of cardboard, in known manner, and formed to from two sets first flaps respectively secured to two first opposite main walls 5.
- the two other opposite main walls 6, or second main walls each comprise a second flap 7, for example rectangular, respectively connected to said corresponding wall 6 by a fold line, the second flaps 7 being fixed to the internal face 8 of their main wall. corresponding by bonding, for example using an adhesive of the type known by the English name "hot melt".
- each second flap 7 comprises a tongue 9, for example rectangular forming an angle, located in the middle of each of the second flaps, to constitute an intermediate support during stacking of the plates.
- this stacking can then be easily carried out by successive layers of trays arranged perpendicular to each other.
- FIG. 1a shows a tray 1 similar to tray 1 which does not include sidewalks 4 and / or corner angles, but first flaps 7 'of identical type to the second flaps 7, that is to say rectangular and fixed to the internal faces of the first corresponding main walls 5 by gluing.
- Each first flap has a tongue 9 ′, for example rectangular forming an angle, of width (dimension of the tongue parallel to the fold line) equal to 1/3 or 1/4 of the length
- Figure 3 shows in section on a larger scale the angle 10 of Figure 1 formed by the tongue 9 cut on its sides 11 and connected to the main wall 6 by a fold line 12.
- the sides 11 can be partially precut or even weakened to be easily detachable from the rest of the second flap, the tongue thus constituting a frangible zone.
