TRAY, BLANK AND PACKAGING FOR BOXES OR CYLINDRICAL PRODUCTS
The present invention relates to a cardboard sheet packaging tray for at least one ply of identical cylindrical products such as boxes with round lid, comprising a bottom and a belt of main side walls including two first opposite side walls connected to the bottom by first fold lines, and two second opposite side walls connected to the bottom by second fold lines perpendicular or substantially perpendicular to the first fold lines.

 It also relates to a blank for the production of such a tray and a packaging comprising boxes with round covers or cylindrical products, for example in their primary packaging, manufactured with such a blank.

 It finds a particularly important although not exclusive application in the field of trays for dairy products, such as cheeses in boxes of the camembert or coulommiers type, stored stacked on pallets of standardized dimensions.

 Packages are already known in the form of a rectangular case for cheese, as shown under the reference 1 in FIGS. 1 and 2. The cheeses are stored in identical rows 2.3 of boxes 4, for example two rows of five boxes, to form a layer 5 of three times two cases, for pallet of standardized size.

<Desc / Clms Page number 2>

Such packaging has drawbacks.

They do not allow optimized storage of boxes by layer of pallets. For the same dimension, excluding any packaging, they can only be used with one type of box or cheeses of given dimensions.

 The present invention aims to provide a tray, a blank and a packaging which respond better than those previously known to the requirements of practice, in particular in that it allows with the same tray to pack boxes or cylindrical products of shape and different dimensions, isomodularly, while increasing the number of boxes per layer of pallets compared to the trays of the prior art.

 This results in a reduction in cost, weight, the number of shelf references and the number of pallets to be managed, which generates significant transport and handling gains.

 Packaging only requires one type of machine, which leads to increased flexibility and the possibility of standardization between different factories of the same company.

 Having identical packaging for boxes of different products will allow mixing of the trays on the pallets and therefore better filling of the pallets, resulting in greater load stability and a reduction in storage costs, transport and handling.

 To this end, the present invention provides in particular a packaging tray made of cardboard sheet material for at least one sheet of identical cylindrical boxes or products, comprising a

<Desc / Clms Page number 3>

 bottom and a belt of main side walls including two first opposite side walls connected to the bottom by first fold lines, and two second opposite side walls connected to the split by second fold lines perpendicular or substantially perpendicular to the first fold lines, characterized in that each of the second walls is formed by at least three panels, namely a central flap, and at least two lateral flaps, glued on each side to said central flap, said second wall comprising two crushed or hollowed-out zones, each zone being of horizontal section of complementary or substantially complementary shape to that of a box or cylindrical product sector and of sufficient vertical height to allow it to be embedded.

 By cylindrical box or product sector, we mean the disc segment formed by the product, the box or its cover, or the portion of the periphery of product, box or cover inscribed in a central angle between about 100 and a few degrees, over a determined maximum radial height of segment b, varying from 1 mm, or even 2 mm to a few millimeters, for example 10 mm. The height or thickness b is sufficient to allow embedding of the sector of the cover in the wall of the plate, possibly by entirely crossing said wall.

 By sufficient vertical height is meant a vertical dimension at least equal to the height or thickness of the cylindrical product, the box, or

<Desc / Clms Page number 4>

 of the lid of the box intended to be placed in the tray.

 In advantageous embodiments, recourse is had to one and / or the other of the following arrangements: the crushed or hollowed-out area is in one piece and extends over a height greater than or equal to the two-thirds of the flap, for example over a height greater than or equal to three-quarters or four-fifths, or even over the whole of the width of the flap.

 - the crushed or hollowed out area is a hollowed out area over a partial thickness of the wall; - the crushed or hollowed-out area has a vertical height equal to or slightly greater than the height of a box cover; - The walls are of sufficient height to contain at least two layers of stacked boxes.

 Advantageously, the tray is arranged to contain three or four superimposed layers and / or the boxes are placed upside down, cover downwards in particular in the case where the crushed or hollowed out areas are of smaller heights than those of the walls; - The overall lateral and longitudinal dimensions of the plate are respectively of the order of 300 mm and of the order of 400 mm.

 By of the order of, I mean 1 to 3 mm; - The lateral flaps are glued to the internal face of the central flap, the hollowed out or crushed areas belonging to said lateral flaps;

<Desc / Clms Page number 5>

 - Conversely, the side flaps are glued to the external face of the central flap, the hollowed out or crushed areas belonging to said central flap; - The first opposite side walls are respectively provided on either side on their side, with a set of two side flaps, namely a first side flap, suitable for forming a cut corner and a second side flap, the area crushed or hollowed out being on one and / or the other of the first and second lateral flaps.

 The cutaway is considered to be part of the second wall.

 Such an arrangement thus allows better locking of the end boxes in the tray, which come to bear on the biased flap or flaps forming a cut corner; - The central flap of the second opposite side walls is devoid of flaps, and is smaller than the height of said first walls.

 By devoid of flap, it should be understood here that no flap is attached to it by fold lines. However, two flaps are attached to it.

 The invention also provides a blank allowing the formation of the tray as described above.

 It also proposes a blank for the constitution of a packaging tray made of cardboard sheet material for at least one sheet of cylindrical boxes or products, comprising a rectangular or substantially rectangular central panel provided on each side with a rectangular flap or substantially rectangular, namely:

 In an advantageous embodiment, the boxes are stacked upside down.

 Advantageously, the flaps, glued to the second flaps to form the second, are parallel to the two peripheral rows of three products or boxes.

 In another embodiment, the glued flaps are perpendicular to the two peripheral rows of three products or boxes.

The invention will be better understood on reading the following description of embodiments given by way of nonlimiting examples. The description refers to the accompanying drawings in which:
Figures 1 and 2, already announced, respectively show a top view of a tray and a layer of pallet trays, containing boxes with round lid, according to the prior art.

 Figures 3 and 4 show a top view of a tray and a layer of pallet trays, according to the embodiment of the invention more particularly described here.

 Figures 5,6 and 7 show, in top view, three identical trays according to the embodiment of the invention of Figures 3 and 4, each comprising a box model with a round cover of different diameter.

 Figure 8 is a plan view of a two-layer blank, according to a first embodiment, for cut corner tray.

Figure 9 is a plan view of a blank according to another embodiment of the invention, with four layers.

 FIG. 10 is a sectional view of two superimposed plates respectively obtained with a blank of the type corresponding to that of FIG. 9.

 FIG. 11 is a plan view of a blank according to another embodiment of the invention, with several layers, but with crushed embedding zones for a tray with cut corners.

 FIG. 12 shows a simplified operating diagram giving an embodiment of a method for the constitution of packages of boxes with round lid, according to the invention.

 Figures 13, 14, 15 and 16 show, in top view, other embodiments of trays according to the invention, respectively with boxes of 115 mm in diameter, 112 mm (1st mode and 2nd mode) and 110 mm.

 As already mentioned above, FIGS. 1 and 2 respectively show a tray 1 and a layer 5 of trays 1 for boxes 4 with a round cover of known type.

 The boxes 4 are arranged in two rows 2,3, the boxes 1 then being palletized in the form of three rows of two trays.

 On a standard pallet of length 1200 mm and width 800 mm, it is thus possible to have six trays or cases 1 (each of dimensions 590 mm x 260 mm) of ten boxes, or sixty boxes per layer.

<Desc / Clms Page number 10>

Figure 3 shows an embodiment of tray 6 according to the invention, with eight boxes 4 per tray.

 The plates here occupy an area of 300 mm x 400 mm, which allows, on the same pallet 7 of 1200 mm x 800 mm, to place eight plates 6, or sixty four boxes 4 per layer.

 In the following description, the same reference numbers are used to designate identical or similar elements.

 Figures 5,6 and 7 show the embodiment of the package 8 according to the invention more particularly described here, in which are respectively placed three series of boxes 9,10, 11, with round cover, of three different diameters.

 FIG. 5 shows a double-sided corrugated cardboard packaging, for example 2 mm thick, formed by a tray with cut corners, overall length 1 = 400 mm and overall width L = 300 mm, containing boxes 9 with round cover, diameter d = 113 mm.

 More specifically, the boxes 9 are arranged in a staggered staggered fashion, namely two peripheral rows 12, 13 of three end boxes and a central row 14 of two middle boxes.

di, deux boîtes adjacentes d'une même rangée périphérique étant séparées entre elles par une deuxième distance d2 et les deux boîtes médianes, tangentes avec chacune des six boites d'extrémité, étant séparées entre elles par une troisième distance The covers of the end boxes located at the opposite angles of the two peripheral rows are separated from each other by a first distance

di, two adjacent boxes of the same peripheral row being separated from each other by a second distance d2 and the two middle boxes, tangent to each of the six end boxes, being separated from each other by a third distance

d3. Ces distances sont bien évidemment à considérer avec la tolérance habituelle observée pour ce type d'emballages et de boîtes, c'est-à-dire par exemple de l'ordre de 1 ou 2 mm.

d3. These distances are obviously to be considered with the usual tolerance observed for this type of packaging and boxes, that is to say for example of the order of 1 or 2 mm.

 The dimensions of the boxes and the distances between them then imply embedding of the four corner boxes of the two peripheral rows in the end flaps 15 glued to the opposite walls 16 over a width x of the order of 4 to 5mm.

 Figure 6 shows the same tray 8 containing. this time boxes with a round lid of diameter = 112 mm.

 The first, second and third distances here are i, d'2 and d's respectively, determined geometrically for fitting into the end flaps 15 ′ glued to the walls 16 ′ over a distance x ′ of the order of 0, 5 mm.

 Figure 7 shows the same tray containing lid boxes with a diameter of = 110 mm.

 In this case, there is no embedding of the end boxes of the peripheral rows 12 and 13, in the flaps 15 '' glued to the opposite walls 16 ".

 The first, second and third distances are respectively of 1, 2 and 3, different from the previous ones of i, 2 and 3 and geometrically calculable so as to be within human reach of career.

 Thus with the same tray 8, it is possible to pack boxes with different cover diameters of 113 mm, 112 mm and 110 mm.

 FIG. 8 shows a blank 17 of corrugated cardboard sheet allowing the manufacture of a tray according to

<Desc / Clms Page number 12>

 another embodiment of the invention, for two superimposed layers of round boxes of cheeses arranged upside down.

 The blank 17 comprises a central panel 18 formed by a rectangle whose end angles are cut at an angle.

 The panel 18 is provided on its transverse sides with two first rectangular flaps 19 connected to the panel by first fold lines 20, each first flap comprising on either side a first rectangular flap 21 of width equal or substantially equal to that of the oblique portion 22 of the end angle of the central panel, said first flap being connected on one side to the flap, by second fold lines 23, perpendicular to the first, and connected on the other side to a second rectangular flap 24, by third fold lines 25, parallel or substantially parallel to the second fold lines 23.

 The second flaps 24 comprise for example stacking studs 26, centered or offset with respect to the tenons of the flaps of the flap opposite symmetrically with respect to a center line 27 of the flap and suitable for cooperating with recesses 26 'located at the fourth line level folding 28, joining the plate 18, with two second rectangular flaps 29, devoid of flap, occupying the sides adjacent to the first flaps 19.

 The second flaps 24 each respectively comprise a recess or crushing zone 30, rectangular, of longitudinal dimension equal to or slightly greater than that of a sector of the cheese box of larger diameter capable of being

<Desc / Clms Page number 13>

emballée dans le plateau, ce qui permet donc l'encastrement de chaque couche superposée dans le volet en vis-à-vis, comme précédemment décrit.

packed in the tray, which therefore allows the embedding of each superimposed layer in the visor vis-à-vis, as previously described.

 The recesses are in fact arranged in height to correspond to the location of the box covers of each layer here piled upside down, and thereby allowing the embedding of the cover sector opposite, at the correct height .

 The tray further comprises ventilation holes 31 in a manner known per se and / or grip handles 32.

 FIG. 9 shows another embodiment of a blank 33 according to the invention, for four layers or layers of boxes.

 Four recesses 34 over a height of the order of 4/5 of the second flap 35 from the bottom are provided here.

 More specifically, the panel 18 is connected to two first slightly trapezoidal flaps 36, the second and third lines 37 and 38 joining with the first and second flaps 35 and 39 being slightly oblique to give a trapezoidal shape in section.

 FIG. 10 shows in section two plates 40 for four layers or layers of boxes 41 (in dashed lines in the figure), obtained with blanks of the type shown in FIG. 9.

 The second flap 35 is glued inside the second flap.

 FIG. 11 shows another embodiment of blank 42 according to the invention with four sides.

 The blank 42 comprises a central panel 43 and four side flaps, namely two first flaps

<Desc / Clms Page number 14>

rectangulaires 44 munis de rabats d'extrémité 4o et deux seconds volets rectangulaires 46 dénués de rabats.

rectangular 44 provided with end flaps 4o and two second rectangular flaps 46 devoid of flaps.

 Each of the flaps 45 is provided in its center with a crushed, rectangular, continuous part 47, of width y equal to or slightly greater than the maximum length of the lid sector of the larger diameter box intended to be packed in such a tray, and of height for example equal to 4/5 of the height of the flap 45.

 We will now describe a method of forming a package according to the invention by lateral casing of the boxes 4.

 The boxes are brought to a track 50 and blocked by a decompression stop 51.

The following steps are then implemented:
52: Accumulation of boxes
53: Stacking boxes (on two, three or four levels)
54: Selection of two or three stacks of boxes
55: Transfer of a set of three batteries to a support plate (not shown)
56: Transfer of a set of two batteries to the plate
57: Transfer of a set of three batteries to the plate
58: The eight correctly spaced stacks 59 are then simultaneously transferred to be capped by the blank (not shown) at 60.

 The assembly is then reassembled vertically in a conformator (vertical cavity, not shown).

 Finally, at the outlet of the cavity, the whole is turned over, the open face of the tray then being at

<Desc / Clms Page number 15>

 on top, while the boxes are upside down in the tray. These last two steps have not been shown diagrammatically in the figure either.

 In this principle, the spacing between the stacks of boxes is achieved by cylinder end pieces 61 fitted with shaped plates 62 for the separation of the sets of three stacks, and by a cylinder end piece 63 of the cylindrical type for the separation of boxes power stations belonging to the sets of two batteries.

 FIGS. 13, 14, 15 and 16 show, in top view, a plate 70 with eight sides, of corrugated cardboard, for a sheet of identical products, with a round cover, comprising a bottom 71, for example of a piece, and a belt of main side walls, including two first opposite side walls 72, and two second opposite side walls 73.

 The second side walls 73 are formed by five panels, namely a central flap 74 and two sets of two side flaps comprising an end flap 75 glued to the internal face of the flap 74 and an intermediate flap 76, forming a cut corner.

 FIGS. 13, 14, 15 and 16 show the different modes of filling the tray 70 with boxes of different diameters and / or different mounting arrangements.

 The boxes are arranged in two peripheral rows 77 of three boxes and a central row 78 of two boxes the axis of the peripheral rows being perpendicular to the second walls.

 Figure 13 shows a tray 300 x 400 mm with boxes with an external diameter d = 115 mm.

<Desc / Clms Page number 16>

 The end boxes 80 are here embedded in their respective end flaps 75, over the entire thickness of the latter, (ie 5 mm), which are therefore entirely hollowed out on a part corresponding to the corresponding cover sector, this which makes said covers tangent to the internal face of the central flap 74.

 The covers also bite over a small thickness el, of the order of 2 mm, into the intermediate flap 76.

 Finally, the central boxes 81 of the peripheral rows are, for their part, embedded in the first wall, at its center over the thickness of the latter.

 More precisely, the boxes are here separated from each other for the first, second and third distances x, = 70 mm, X2 = 22 mm and X3 = 22 mm the embedding in the end flaps is done over a length X4 = 49 mm and in the first wall.

 Figure 14 shows the tray 70 filled with boxes with a diameter of = 112 mm.

 Here the first, second and third distances are x'l = 65 mm, X'2 = 22.6 mm and x'3 = 20 mm with a recess e'i of the end boxes 82 in the flaps 75 of 1, 6 mm and an e'2 recess of the central boxes 83 of 2 mm.

 FIG. 15 gives another embodiment of embedding boxes with a diameter d '' = d '= 112 mm, in which only one embedding of the end boxes 84 of e' '= 4 is provided. , 3 mm, the middle boxes 85 being tangent to the internal face of the first wall 72.

<Desc / Clms Page number 17>

The first, second and third distances are here x''i = 65 mm, x''2 = 25.3 mm and x''3 = 25.3 mm.

 Figure 16 shows the tray 70 with boxes 86 with a diameter of '' = 110 mm. Here no embedding is necessary, the boxes being for example separated for the first, second and third distances x '' 'i = 69 mm, x' '' 2 = 18 mm = x '' '3.

 Thanks to the invention, not only can several dimensions of boxes be packed in the same tray, but in addition, the recesses in general used allow good immobilization of the boxes in the packaging.

 As is obvious and as also follows from the above, the present invention is not limited to the embodiments more particularly described. On the contrary, it embraces all variants and in particular those where the number of boxes per layer is greater, or even those where the short side of the packaging is that provided with flaps and not the large one as shown in FIGS. 5 to 7 , those where there is also and moreover at least one crushed or hollowed out area on the first walls, for example in the center of said walls and / or in the center and on the ends, allowing the embedding of a stack of central boxes on a part of their cover, said areas having a shape complementary or substantially complementary to that of a sector of said cover over a sufficient height, those where the embedding will vary in height, the section of the package being trapezoidal.
