Description

The subject of the present invention is a packaging of the so-called "integrated pallet" type consisting of elements to be assembled, made of a rigid material, such as corrugated cardboard, from blanks provided with fold lines making it possible to form at least the side walls of the packaging, the bottom of the latter, the hollow profiles associated with said bottom to form the pallet and the means cooperating with the hollow profiles to make them non-deformable when the packaging is used.

Known for the support of packages and for their handling using forklifts, pallets generally consisting of an assembly of slats and wooden blocks extending under the entire surface of the bottom of the packages. These pallets have significant drawbacks, the main ones being their dead weight, their size and their cost, the latter being such that they are generally recovered, which leads to other drawbacks, namely in particular storage and transport costs of empty pallets. .

To overcome these drawbacks, various devices have been devised consisting of elements to be assembled with the packaging to form a pallet, these elements being lighter and less expensive than conventional wooden pallets. These devices can be classified into three categories, namely: studs, usually made of plastic, which are either attached by strapping to the bottom of the package, or glued to the latter; parallel pads fixed to the bottom of the package by connecting members presented by the pads and hollow profiles, made of the same material that the packaging, fixed parallel to each other at the bottom of the packaging and whose rigidity is ensured by separate elements, such as profiled parts, blocks of expanded plastic material, slipped inside said hollow profiles.

The invention relates to a system belonging to the latter category and aims, on the one hand, to remedy the drawbacks presented by the known embodiments and in particular to the major drawback which resides in the fact that the latter are constituted of a relatively large number of elements, these elements being of complex manufacture and their assembly requiring labor and significant facilities and, on the other hand, providing an integrated pallet packaging consisting of an extremely large number reduced of constituent elements, simple to manufacture and easy to assemble, cooperating with one another to simultaneously ensure the assembly of the elements and the rigidity of the hollow sections constituting the pallet.

To this end, according to the invention, the packaging comprises, to produce its side walls, its bottom, at least two hollow sections constituting the pallet and the means for making the latter non-deformable, two elements, a first element intended to constitute the bottom of the packaging and the hollow profiles forming the pallet and a second element intended to constitute the side walls of the packaging and the means intended to make the hollow profiles non-deformable, these means, presented by the second element, being arranged to cooperate with the first element to help assemble it to the second element.

According to an advantageous embodiment of the invention, the blank from which the first element is made has the shape of a rectangle, this blank having fold lines, parallel to the short sides of the rectangle and formed on one side of the blank , the two fold lines closest to the center of the blank defining a central panel while the other lines folding lines delimit, on each side of the central panel, at least three panels, the distances separating the folding lines delimiting the first panels, counted from the central panel, reduced by twice the thickness of the blank, and the distances separating the fold lines delimiting the third panels, counted from the central panel, reduced by the thickness of the blank, being substantially equal and corresponding to the internal dimension of the hollow sections taken perpendicular to the bottom of the package, the distance separating the fold lines delimiting the second panels, counted from the central panel and corresponding to the internal dimension of the hollow profiles taken parallel to the bottom of the package and perpendicular to the longitudinal axis of said profiles correspond to a maximum of half the distance separating the two fold lines delimiting the central panel reduced by four times the thickness of the blank, the first element being formed é, from said blank by bringing the third panels perpendicular to the central panel and in the same direction, authorized by the fold lines, delimiting these third panels, by folding the second panels perpendicular to the central panel and in the same direction as that of the panels so that the latter are directed towards each other and by folding down the first panels perpendicular to the central panel and in the same direction as that of the third panels so that the latter are supported on the central panel, this packaging having, when '' it is formed using two elements, a section, taken parallel to its bottom and through its side walls, which is octagonal, the blank from which the second element is made being in the shape of a rectangle whose dimension of short sides is equal to the height of the side walls themselves of the packaging increased by the distance separating the fold lines delimiting the first p the aforementioned rings of the blank constituting the first element and of the thickness of the latter blank, the blank constituting the second element being subdivided into eight panels delimited by fold lines parallel to the short sides of this blank and formed on one of the sides of the latter, these eight panels being distributed in two groups of three consecutive panels, separated from each other by a panel, each presenting, along the long side of the rectangle near which the second element will be assembled to the first element and symmetrically with respect to the axes of the central panels of the group, parallel to the fold lines delimiting these panels, a first cut made along a fold line delimiting the groups, from the long side of the rectangle, over a distance slightly greater than the distance separating the external faces of the aforementioned hollow profiles parallel to the bottom of the packaging, a second cut made in the extreme panels of said groups and parallel to the long side of the blank from the end of the first cut and this over the entire distance delimiting the panels x extremes of the two groups to form a foldable tab perpendicular to the central panel, the blank of the second element having, along one of its short sides, a tab intended to be assembled during the formation of the packaging at the extreme panel located along the other side of the blank.

The packaging 1, according to the invention and illustrated in the drawings, comprises, to produce its side walls 2, its bottom 3, an integrated pallet consisting of two hollow sections 4 and means 5 to make the latter non-deformable, two elements 6 and 7. A first element 6 is intended to constitute the bottom 3 of the packaging and the hollow sections 4 forming the pallet while a second element 7 is intended to constitute the side walls 2 of the packaging as well as the means 5 provided to make the hollow sections 4 undeformable, these means 5, presented by the element 7, being arranged to cooperate with the element 6 during the assembly of the latter to the second element.

Figures 1 and 2 illustrate the simplest embodiment of the pallet. This consists of a first element 6 which has the shape of a rectangle. On one side of this blank 8, all the fold lines are practiced, parallel to the short side of the above rectangle, which make it possible to form the pallet. The two fold lines closest to the center of the blank define a central panel 12, while the other fold lines define, on either side of the central panel 12, four panels 13, 14, 15 and 16. The distances d ³¹ which separate the fold lines 10 delimiting the first panels 13, reduced by twice the thickness 2 of the blank. and the distances d 37 which separate the lines folding 10 delimiting the third panels 15, reduced by the thickness e of the blank, are substantially equal and correspond to the internal dimension d ⁴ of the hollow sections 4 taken perpendicular to the bottom 3 of the package. The distance d which separates the fold lines 10 delimiting the second panels 14 and which corresponds to the internal dimension d of the hollow sections 4, taken parallel to the bottom of the package and perpendicular to the longitudinal axis 17 of said sections, corresponds to the maximum at half the distance d separating the two fold lines delimiting the central panel 12 reduced by four times the thickness e of the blank. The first element 6 is formed, from said blank 8 by bringing the third panels 15 perpendicular to the central panel 12 and in the same direction, authorized by the fold lines 10 delimiting these third panels 15, by folding down the second panels 14 perpendicular to the central panel 12 and in the same direction as that of the panels 15, so that the latter are directed towards each other, and by folding down the first panels 13 perpendicular to the central panel 12 and in the same direction as that of the third panels 15 so that the latter bear on the central panel 12.

In the embodiment illustrated in Figures 3 and 4, the blank 8 from which the first element 6 is formed also has the shape of a rectangle. This blank has fold lines 10, parallel to the short sides of the rectangle. The two fold lines closest to the center of the blank define a central panel 12, while the other fold lines define, on either side of this central panel, four panels 13, 14, 15, 16. The lines folding 10 delimiting the central panel 12 and the three neighboring panels 13, 14 and 15, considered from the central panel 12, are formed on one side of the blank, while the two folding lines 10 "separating the two end panels 16 third panels 15 are formed on the other face blank. The distances d separating the fold lines 10 delimiting the first and third panels 13 and 15 are substantially equal and correspond to the internal dimension d ⁴ of the hollow sections 4 taken perpendicular to the bottom 3 of the package. The sum of the distances d separating the fold lines 10 delimiting the second panels 14, and corresponding to the internal dimension d ^{5 ′} of the hollow sections 4, taken parallel to the bottom of the packaging and perpendicular to the longitudinal axis 17 of said sections, and of the dimensions of the fourth end panels 16, taken parallel to the long sides of the rectangle, being at most equal to the distance d separating the fold lines 10 delimiting the central panel 12, reduced by four times the thickness of the blank. The aforementioned element 6 is formed, from said blank 8, by bringing the first two panels 13 in the same direction and perpendicular to the central panel 12, by folding down the second panels 14 parallel to the central panel 12 so that they are directed l 'towards each other, by folding the third panels 15 towards the central panel 12, perpendicular thereto and by applying the fourth panels 16 on said central panel.

In its embodiment illustrated in Figures 5 and 6, the blank 8, from which the first element 6 is formed, also has the shape of a rectangle. This blank has fold lines 10, parallel to the short sides of the rectangle. The two fold lines closest to the center of the blank define a central panel 12, while the other fold lines define, on either side of the central panel 12, four panels 13, 14, -15 and 16. The fold lines 10 'which delimit the central panel 12, the four neighboring panels 13 and 14 and the end parts of the fold lines separating the third panels 15 from the fourth panels 16 are formed on one side of the blank, while the central parts 10 "of these last fold lines are made on the other side of the blank. Cutouts 10"'are provided, substantially perpendicular to the fold lines delimiting the fourth panels 16 and over the entire width of the latter, to divide them into three flaps 160 and 161. The sum of the distances d which separate the fold lines 10 delimiting the second panels 14, and the dimension d ⁶ of the two end panels 16, taken parallel to the long sides of the rectangle, is at most equal to the distance d separating the fold lines 10 delimiting the central panel 12, reduced by four times the thickness e of the blank, while the distance d ⁶ which delimits the fourth panels 16 is at most equal to the internal dimension d ^{5 ′} of the hollow sections 4. The above-mentioned first element 6 is formed by bringing the four end flaps 160 of the fourth panels 16, in the same direction, authorized by the fold lines 10 ', by folding down the third panels 15, perpendicular to the central panel 12 and in the same direction as that of said end flaps 160. so that the latter iers are directed towards each other, by folding down the second panels 14 perpendicularly to the central panel 12 and in the same direction as that of the flaps 160, so that the latter are directed towards the central panel i2 and by folding down the first panels 13 perpendicularly to the central panel 12 and in the same direction as the flaps 160 for applying the latter, as well as the flaps 161 of the fourth panels 16 on said central panel 12.

The packaging according to the invention and which is illustrated in Figures 7 and 8 is formed using the two elements 6 and 7 above and has, in the assembled position (Figure 8), a section, taken parallel to its bottom 3 and through its side walls 2, which is in the form of an irregular octagon. The blank 18 from which the second element 7 is formed, intended to form the side walls of the packaging and the means 5 making the hollow sections 4 of the pallet non-deformable, is in the shape of a rectangle whose dimension of the short sides is equal at the height h of the side walls properly say of the packaging increased by the distance d ³ separating the fold lines 10 delimiting the aforementioned first panels 13 of the blank 8 constituting the first element 6 and of the thickness e of the latter blank. The blank 18 which constitutes this second element 7 is divided into eight panels delimited by fold lines 10 parallel to the short sides of this blank and formed on one of the faces of the latter. These eight panels are divided into two groups 19 of three consecutive panels 20, 21 and 22, separated from each other by a panel 23, each having, along the long side 24 of the rectangle near which the second element 7 will be assembled to the first element 6 and symmetrically with respect to the axes 28 of the central panels 21 of the group parallel to the fold lines delimiting these panels, a first die 26 made along the fold lines 10 delimiting the groups 19, starting from the large side 24 of the rectangle, over a distance d slightly greater than the distance d separating the external faces 27 of the above-mentioned hollow sections 4 which are parallel to the bottom of the packaging, each of the groups 19 has a second cut 31 made in the end panels 20 and 22 of said groups 19 and parallel to the long side 24 of the blank from the end of the first cut 26 and this over the entire distance d ¹⁰ delimiting the end panels 20 and 22 of the two groups 19 for form a tab 34 which can be folded down perpendicularly to the central panel 21. The blank 18 finally has, along one of its short sides, a tab 35 intended to be assembled during the formation of the package at the end panel situated along the other side of the blank.

In the embodiment of the package 1, illustrated in Figures 9 to 12, it has a section, taken parallel to its bottom 3 and through its side walls 2, which has the shape of a regular octagon. The blank 8, from which the first element 6 is formed, has the shape of a rectangle whose short side is equal to the distance d ² separating the internal faces 9 (see figure 10) of two opposite side walls 2 of the packaging. This blank 8, as illustrated in FIG. 3, has fold lines 10 and 10 'parallel to one of the short sides of the rectangle and arranged symmetrically with respect to the axis of symmetry of the rectangle, of trace 11 ( see figure 3), parallel to this. small side. The two fold lines 10 closest to this axis of symmetry 11 delimit a central panel 12 intended to simultaneously constitute the bottom 3 of the package and one of the walls of each of the hollow sections 4, the distance d separating these two lines of folding being substantially equal to the distance d ² separating the abovementioned internal faces 9 reduced by twice the thickness e of the blank 8. The other folding lines 10 and 10 ′ delimit, on either side of this central panel 12, four panels 13, 14, 15 and 16, the fold lines 10 delimiting the central panel 12 and the three neighboring panels 13, 14 and 15 being formed on one side of the blank, while the two fold lines 10 'separating the two end panels 16 of the panels 15 are formed on the other face of the blank 8. The distances d which separate the fold lines 10 and 10 ′ delimiting the first and third panels 13 and 15 are substantially equal and correspond to the internal dimension d of the cr profiles them 4 taken perpendicular to the bottom 3 of the package. The distance d5, which separates the fold lines 10 delimiting the second panels 14, and which corresponds to the internal dimension d of the hollow sections 4 taken parallel to the bottom 3 of the package and perpendicular to the longitudinal axis of trace 17 of said sections , is substantially equal to one third of the distance d separating the fold lines 10 delimiting the central panel. The dimension d ⁶ of the end panels 16, is substantially equal to one sixth of the distance d ¹ separating the fold lines 10 delimiting the central panel 12. The element 6 is formed, from the blank 8, by bringing the panels 13 into the same direction and perpendicular to the central panel 12, folding the panels 14 parallel to the central panel 12 so that they are directed towards each other, by folding the panels 15 towards the central panel 12, perpendicularly thereto, and by applying the end panels 16 to said central panel. The blank 18, from which the second element 7 is made, is in the shape of a rectangle, the dimension of its short sides being equal to the height h of the side walls proper of the packaging increased by the distance d ⁶ corresponding to the distance d ³ separating the fold lines 10 delimiting the panels 13 of the blank 8 constituting the first element and of the thickness e of this blank 8. The dimension of the long sides of the rectangle is equal to the perimeter of an octagon circumscribed to a circle whose the diameter is equal to the short side of the blank 8. The blank 18 is subdivided into eight equal panels delimited by fold lines 10 parallel to the short sides of the blank made on one of the sides of the latter. Two groups 19 of three consecutive panels 20, 21 and 22, separated from each other by a panel 23, each have, along the long side 24 of the rectangle near which the element 7 will be assembled to the first element 6 and symmetrically with respect to the axis 25 of the central panel 21 of the group parallel to the fold lines 10 delimiting this panel, a first cut 26 made along the fold lines 10 delimiting the group, from the long side 24 of the rectangle, over a distance d ⁷ slightly greater than the distance d ⁸ separating the external faces 27 of the hollow sections 4 parallel to the bottom of the packaging, a second cut 28 made in the panels 20 and 22 of the group parallel to the cut 26 and on the same distance d 7 as the latter, the distance d ⁹ separating these two cutouts 26 and 28 being at least equal to half the distance d ¹⁰ separating the fold lines 20 delimiting these panels 20 and 22, a first fold line 29 , parallel to g rand side 24 of the rectangle and made on the same side of the blank as the fold lines 10, bringing together the bottoms of the cutouts 26 and 28 to form a flap 30 which can be folded perpendicularly to the panel 20 so to cooperate with the bottom 3 of the packaging formed by the element 6 to ensure the fixing of the latter to the second element 7. A third cut 31 is made in the end panels 20 and 22 of the group, from the bottom of the cutout 28 and in the extension of the fold line 29 to extend into the central panel 21 of the group, a second fold line 32, formed in the latter panel 21, parallel to the cutouts 26 and 28 and on the same face of the blank than the other fold lines, extending from the cutout 31 to the long side 24 of the rectangle. The distance d ¹¹ which separates these two fold lines 32 produced in the central panel 21 of the group is substantially equal to the distance d ¹² separating the internal faces 33 from the walls of the two hollow sections perpendicular to the bottom of the nearest package l one of the other. The tabs 34 delimited by the cutouts 28 and 31 and by the fold lines 32 are intended to be folded back inside the hollow sections 4 on the internal faces 33 of the latter, to prevent deformation of the sections 4 when they are under charge. The blank 18 of the second element 7 has, along one of its short sides, a tab 35 intended to be assembled, during the formation of the package, to the end panel located along the other short side of the blank .

The blank 18 is subdivided into four panels 38, 39, 40 and 41 equal two by two and delimited by fold lines 10 parallel to the short sides of the blank and formed on one of the sides of the latter. The two panels 39 and 41 intended to cooperate with the first element 6, along the longitudinal axis 17 of the hollow sections 4, have a dimension, taken parallel to the long sides of the blank, which is equal to the short sides of the blank 8 constituting this first element 6 reduced by twice the thickness e of the blank 18 constituting the second element 7. The other two panels 38 and 40 of this blank 18 have a dimension, taken parallel to the long sides of the blank, which is equal to the corresponding dimension d of the central panel 12 of the blank 8 increased by twice the thickness e of the latter blank. These last two panels 38 and 40 are separated from the other two panels 39 and 41, along the long side 42 of the rectangle near which the second element 7 will be assembled to the first, by cutouts 43 made along the fold lines 10 delimiting the panels, from the long side 42 of the rectangle and over a distance slightly greater than the distance d ⁸ separating the external faces 27 of the hollow sections 4 parallel to the bottom 3 of the packaging. These latter panels 38, 40 each have a fold line 46, parallel to the long side 42 of the blank 18, joining the cutouts 43, near their bottom, to form two legs 47 which can be folded perpendicular to the panel in order to cooperate with the bottom 3 of the packaging formed by the first element 6 to secure the latter to the second element 7. The parts 61 of the panels 39 and 41, projecting from the bottom of the packaging, cooperate with the external sides 62 of the profiles hollow 4 to make them non-deformable.

The distances d separating the fold lines 10 delimiting the first and third panels 13 and 15 are substantially equal and correspond to the internal dimension d ⁴ of the hollow sections 4 taken perpendicular to the bottom 3 of the package. The distance d5 separating the fold lines 10 delimiting the second panels 14 corresponds to the internal dimension d of the hollow sections 4 taken parallel to the bottom of the packaging and perpendicular to the longitudinal axis 17 of said sections and is substantially equal to one third of the distance d between the fold lines 10 delimits as the central panel 12, the dimension of the extreme panels 16 taken parallel to the long sides of the rectangle, being at most equal to one sixth of the distance d separating the fold lines 10 delimiting the central panel 12.

These last two panels 38 and 40 are separated from the other two panels 39 · and 41, along the long side 42 of the rectangle near which the second element 7 will be assembled at the first by first cutouts 43 made along the fold lines 10 delimiting the panels, from the long side 42 of the rectangle and over a distance slightly greater than the distance d ⁸ separating the external faces 27 of the hollow sections 4 parallel to the bottom of the packaging. These panels 38 and 40 each have, symmetrically with respect to their axis 44 parallel to the fold lines 10, two second cuts 45 made parallel to the first cuts 43 and over the same distance as the latter, the distance separating a second cut 45 from the first corresponding cut 43 being of the order of 1/5 of the dimension of the panel considered taken perpendicular to the fold lines 10. These panels 38 and 40 each have two first fold lines 46, parallel to the long side 42 of the rectangle and formed on the same face of the blank as the fold lines 10 delimiting the panels. These lines 46 bring together the bottoms of the first and second cutouts 43 and 45 to form two flaps 47 which can be folded perpendicularly to the panel in order to cooperate with the bottom of the packaging formed by the first element to secure the latter to the second element. Two third cuts 48 are made in each of the panels 38 and 40, from the bottom of the second cuts 45 and in the extension of the first fold lines 46 delimiting the tabs 47, two second fold lines 48, formed parallel to the first and second cuts 43 and 45 and on the same side of the blank as the other fold lines, extending from the third cuts 48 to the long side 42 of the rectangle, the distance d separating these two second fold lines 49 of a panel being substantially equal to the distance d ¹² separating the internal faces 33 of the walls of the two hollow sections perpendicular to the bottom of the package closest to each other. The tabs 50 delimited by the cutouts 45 and 48 and by the fold lines 49 are intended to be folded back inside the hollow sections 4, on the internal faces 33 of the latter, to prevent deformation of the sections 4 when they are under charge. The blank 18 of the second element 7 has along one of its short sides, a tab 35 intended to be assembled, during the formation of the package, to the end panel located along the other short side of the blank.

As shown in FIG. 16, the blank 18 constituting the element 7 may comprise, along its side 51 opposite to the side 42, a rectangular strip 52 delimited by a fold line 53 parallel to the aforesaid large side 42 and produced in the blank on the same face as the other fold lines 10, cutouts 54 being formed in this strip of material, in the extension of the fold lines 10 delimiting the panels, to delimit flaps 55 intended to at least partially close the opening of the packaging.

To facilitate the formation of the element 6, the central panel 12 of the blank 8 comprises, on its face 56 and in the area 57 where the end panels 16 are applied, a layer of self-adhesive material 58 ensuring automatic fixing of the panels 16 from that they are brought into contact with the aforementioned face 56, this fixing possibly being able to be reinforced by staples.

For the same purpose, the tabs 30, 34, 47 and 50, presented by the blank 18 intended to constitute the element 7, are lined on their faces intended to be applied to the bottom 3 of the packaging and on the internal faces 33 of the hollow sections 4, of a layer of self-adhesive material 59 intended to ensure at least partially the fixing of the element 6 to the element 7, this fixing being able to be reinforced by staples. the assembly of the elements 6 and 7 together, the panels 23, 39 and 41 of the blanks 18 each have, at the place where they cooperate with the external faces 62 of the hollow sections 4, a fold line 60 parallel to the sides 24 and 42 of the blanks 18, the space between these fold lines and the sides. 24 and 42 of the blanks being coated with a layer of self-adhesive material 61.

To allow handling using an elevator, the wheels of which penetrate into the hollow sections 4 or to facilitate manual handling of the packaging, the central panel 12 of the blanks 8 has cutouts 63 regularly distributed, outside of the area 57 where the panels 16 are applied, and forming either openings for the passage of the elevator wheels, or handles.

In order to authorize the flat delivery, either of the blanks 8 and 18, or of the elements 6 and 7 assembled from these blanks, the fold lines 10 presented by the latter are produced in such a way that the panels, delimited by these fold lines 10, are practically hinged on each other to be able to overlap.

The elements 6 and 7, which can be produced from blanks having the same thickness, cooperate with each other, when assembled, to ensure the rigidity and the strength of the packaging. As the element 6, which could be made of plastic material to resist humidity, serves both as the bottom 3 and as a pallet for the packaging, it is lighter than known packaging and priced lower than price of these. The lightness of the packaging according to the invention does not, however, adversely affect its resistance and in particular its resistance to stacking, since its side walls 2 are supported over a significant part of their perimeter by the bottom 3. This bottom 3 has been shown in the drawings with the hollow sections 4 directed towards the inside of the package. There is nothing to prevent this bottom from being turned 180 ° so that said profiles hollow 4 are directed towards the outside of the packaging.

It is obvious that the space between the two hollow sections 4, which it communicates with the interior of the packaging as shown in the drawings or that it is located outside the packaging, can be used at various purposes, namely: increased volume of the packaging to receive a bulk material, space for accommodating accessories to be protected, space for disposing of a container emptying system, etc.

It should be understood that the invention is in no way limited to the embodiments described and that many modifications can be made to these without departing from the scope of this patent.

Thus one could provide, as shown in Figures 8 and 20, a first element 6 whose panels 16 are partially folded over the area 57 of the central panel 12 and partially folded, at 63, inside the hollow sections 4. In this case, the tabs 50, ensuring the connection of the elements 6 and 7 with one another as well as the rigidity and the resistance of the sections 4, are applied and fixed to the external faces 64 of said hollow sections.
