    DESCRIPTION
    Object storage and packaging device
    The present invention relates to a reusable and stackable container.
    When products must be transported, it is practical to dispose them in a container. It is desirable to be able to reuse the container and, at the end of its useful life, recycle it. In general, the container has a form of parallelepipedic assembly, of low height. The container comprises a bottom and a perimeter flange. In the past, a container was proposed whose flange was determined by several bends of the edge of a preform whose central part determined the bottom. The requesting firm has realized several drawbacks. The flange has an excessive width. Indeed, it is difficult to form parallel bending lines a short distance from each other. When the flange is determined by winding the preform, the superimposed material thicknesses become too large. Compactness suffers with it.
    The requesting firm has also proposed, in FR 2989670, a stackable tray of false flanges that cover the entire periphery. The flange is constituted from a plurality of portions of an extruded profile fixed to each other.
    The requesting firm has tried to simplify the manufacturing of the tray, while maintaining high rigidity.
    In one embodiment, the object storage and packaging device, in stackable tray configuration, includes a bottom panel in extruded cellular profile and a perimeter flange. The perimeter flange comprises hollow profiled portions welded to the bottom panel and pressure coupled corners each of them in two of said profiled portions. Thus, the profiled portions can be cut transversely to the axis of the profile, which simplifies cutting and handling. The pressure coupling of the corners holds each corresponding profiled portion.
    In one embodiment, each profiled portion is of rectangular general section, with an extension of one of its major walls exceeding the neighboring minor wall and a flap arising from the extension and parallel to said minor wall. The flap, extension and minor wall can determine a groove in which an edge of the bottom tray is installed. The width of the groove can correspond to the thickness of the bottom panel. Complementarity of form takes care of a proper solidarity between the bottom panel and the profiled portion. The groove depth can be equal to
    5
    10

    25
    30
    the width of the profiled portion.
    In one embodiment, the profiled portions are welded to the bottom panel by the flap. Welding can be a thermal spot welding.
    In one embodiment, the profiled portions have a wall thickness between 1 and 2 mm. The profiled portions are provided with solid walls. The profiled portions can be made of polypropylene.
    In one embodiment, the flaps are rectangular in shape. Advantageously, the width of a flap is greater than the width of the neighboring minor wall. In this way, the free end of the flap protrudes from the rest of the profiled portion and, thus, can serve as a guide in the insertion of the bottom panel into the groove.
    In one embodiment, the width of the neighboring minor wall is less than 40 mm, preferably less than 30 mm. Then, the device is particularly compact and has a very high storage and packaging area with respect to the space it occupies. In other words, the relationship between the storage surface offered by the bottom panel and delimited by the flange and the total surface of the device is very high.
    In one embodiment, the profiled portions comprise a chamfer formed at the groove inlet. Said chamfer may be provided in the link between the smaller wall that faces the flap and the larger wall opposite to said extension. Said chamfer can be formed at an angle between 40 and 50 degrees.
    In one embodiment, the profiled portions are far from each other. In this way, an excess thickness is avoided, for example an excess thickness of the flaps. The flaps can be cut transversely to the axis of the profiled portion and at the same time as the rest of the profiled portion.
    In one embodiment, the corners are identical to each other.
    In one embodiment, the corners are formed of injected synthetic material, preferably polypropylene. Advantageously, the whole of the storage and packaging device is made of polypropylene, resulting in simple recycling.
    In one embodiment, each corner comprises a first male part coupled to pressure in one of said profiled portions, a second male part coupled to
    5
    10

    25
    pressure in another of said profiled portions, the second male part being substantially perpendicular to the first male part, and a link in a pressure coupling stop configuration for said profiled portions and comprising a bias outer wall relative to the first part male and the second part male.
    The first and second male parts can be identically.
    In one embodiment, the linkage comprises a bias inner wall relative to the first male part and the second male part.
    In another embodiment, the linkage comprises an inner wall provided with a portion parallel to the first male part and another portion parallel to the second male part.
    In one embodiment, the bottom panel, the extruded profile portions and the flange are made of the same material, for example in polypropylene.
    In one embodiment, the device further comprises at least one wedge python arranged on the bottom panel, at a distance from the flange, at least one thermosetting piton being said to the bottom panel. The pitting python is flush with the upper surface of the profiled portions of the flange.
    The present invention will be better understood with the careful observation of the detailed description of an embodiment taken by way of example in no way limited, illustrated in the accompanying drawings:

    As can be seen in Figure 1, the object storage and packaging device in stackable tray configuration 1 comprises a bottom panel 2 and a flange 3. The
    5

    Bottom panel is made in extruded honeycomb profile. The alveoli are longitudinal or transverse. The bottom panel 2 has a parallel upper surface and a lower surface. The bottom panel 2 can be made of polypropylene. The bottom panel 2 has a general rectangular shape, at this point, of truncated corners. The bottom panel 2 is made of a sheet material. The thickness of the bottom panel 2 can be between 2 and 5 mm, for example 3 to 3.2 mm. To hold the stackable tray 1, the bottom panel 2 can have oblong openings.
    The flange 3 comprises four hollow profiled portions 4 and four corners 5. The hollow profiled portions 4 are parallel two to two. The hollow profiled portions 4 are disjointed. Two hollow profiled portions are mounted on the longitudinal edges of the bottom panel 2. Two hollow profiled portions 4 are mounted on the lateral edges of the bottom panel 2. The hollow profiled portions 4 are welded to the bottom panel 2. The hollow profiled portions 4 have the same profile. The hollow profiled portions 4 are made of a plurality of solid walls, for example solid ones. The profiled portions 4 are preferably made of polypropylene.
    The corners 5 are each pressurized in two profiled portions 4. Each corner 5 comprises a first marginal portion 51 pressurized in a profiled portion 4, a second marginal portion 52 perpendicular to the first and pressure coupled in another profiled portion 4 and a central portion 53 or linkage. The corners 5 are preferably made of polypropylene. It is advantageous that the assembly of the stackable tray 1 is made of polypropylene to facilitate recycling or treatment at the end of its useful life.
    As seen more particularly in Figure 4, the profiled portion 4 has a general rectangular shape. The profiled portion 4 comprises two major walls 40 and 41 parallel. The major walls 40 and 41 are substantially perpendicular to the bottom panel 2. The profiled portion 4 also comprises two parallel minor walls 42 and 43. The smaller walls 42 and 43 are substantially parallel to the bottom panel 2. The width of the smaller wall 43 is less than 40 mm, preferably 30 mm, for example, equal to 26 mm. The walls 40 to 43 define a tubular space 44 in which a corner 5 can be pressurized at each longitudinal end of said profiled portion 4.
    The major wall 40 is continued downward in a coplanar extension 45. At the lower end of said extension 45, a flap or flange 46 is arranged
    5
    5
    10

    30
    substantially parallel to the minor walls 42 and 43. The minor wall 43 and the flap 46 determine a groove 47 whose bottom is determined by the extension 45. The groove 47 is open on the side of the major wall 41. The groove 47 is provided to accommodate an edge of the bottom panel 2.
    The flap 46 has a width greater than the width of the minor wall 42 and the width of the minor wall 43. The flap 46 has a rectangular shape. The flap 46 has its birth at the lower end of the extension 45. The flap 46 extends beyond the major wall 41. The width of a flap 46 is greater than the width of the neighboring minor wall 43. Thus, the flap 46 determines a guide for insertion of the bottom panel 2 into the groove 47.
    The major wall 40 meets substantially at right angles to the minor walls 42 and 43. The major wall 41 meets substantially at a right angle to the minor wall 42 located in opposition to the flap 46. The major wall 41 and the minor wall 43 , neighbors of slot 47, meet in a chamfer 48 conformed to the bias, at this point, substantially at 45 degrees. The chamfer 48 determines a widening in the opening of the groove 47 which further facilitates the insertion of the edge of the bottom panel 2 in the groove 47.
    The said walls of the profiled portion 4 have a thickness between 1 and 2 mm, preferably between 1.3 and 1.7 mm. These walls are solid.
    To make different types of stackable trays, profiled portions 4 whose side dimensions are identical between several types, can be provided, while the height, in other words, the height of the larger walls 40 and 41, can change from one type to another. . Thus, several types of stackable trays can be made with bottom panels of identical thickness and an identical assembly.
    Welding of the bottom panel 2 and of the flange 3 can be carried out on the free face of the flap 46 and through the flap 46. Thus, the flap 46 is fixed to the bottom panel 2. Welding can be carried out by points or by bands. Welding can be done without material input. Welding can be done by local fusion.
    The corners 5 are identical to each other. As can be seen in Figures 5 to 7, corner 5 presents a symmetry with respect to a plane that passes through the middle of the central portion 53. The plane of symmetry passes through the bisector of the angle formed between the first marginal portion 51 and the second marginal portion 52, especially an angle of 90 °. Therefore, the marginal portions 51 and 52 are identical. The description of the

    First marginal portion 51 is also applicable to the second marginal portion 52.
    The first marginal portion 51 has three U-shaped perimeter portions that are joined by the open side of the U in the central portion 53. More precisely, the first marginal portion 51 comprises a first wall 511, a second wall 512, parallel to the first wall 511, and a third wall 513, perpendicular to the first and second walls 511 and 512. As illustrated in Figure 5, the first and second walls 511 and 512 have an equal length. The third wall 513 is linked to one end of the first and second walls 511 and 512. The other end of each wall 511, 512 is linked to the central portion 53.
    As can be seen in Figure 7, the first and second walls 511 and 512 have uneven heights. The lower end of the first wall 511 is located at a level slightly higher than the level of the lower end of the second wall 512. The lower end of the third wall 513 is on a slight slope, which allows said lower free ends to be linked from the first walls. and second 511 and 512, located at different heights. The upper free ends of the first and second walls 511 and 512 are coplanar. The walls 511 and 512 are chamfered in its neighboring corner of the third wall 513 and which is linked respectively to its free lower end and its free upper end. The free upper end of the third wall 513, because of the chamfer, is located at a slightly lower height than the free upper end of the first and second walls 511 and 512. The free lower end of the third wall 513 is located slightly higher than the free end of the first and second walls 511 and 512.
    In other words, the first and second walls 511 and 512 have a rectangular shape, saving the chamfer. The third wall 513 has a rectangular trapecial shape. The first marginal portion 51 comprises a fourth wall 514. The fourth wall 514 is substantially perpendicular to the first and second walls 511 and 512 and the third wall 513. The fourth wall 514 is located substantially at medium height, see Figure 6, of the second wall 512. The fourth wall 514 determines a brace that provides sufficient rigidity to the structure determined by the first and second walls 511 and 512, the third wall 513 and the central portion 53. With the central portion 53, said first walls , second and third 511 to 513 determine a parallelepiped of slightly trapecial section because of the difference in height between the first and second walls 511 and 512. The fourth wall 514 is parallel to the bottom panel 2 and the first, second and third walls 511, 512 and 513 are perpendicular. In the ordinary direction of use of the stackable tray 1, the first, second and third walls 511,512 and 513 are vertical and the

    30
    fourth wall 514 is horizontal.
    The first marginal portion 51 is open from above and open from below, while being closed at half its height by the fourth portion 514. The second marginal portion 52 has an identical structure, while being oriented perpendicularly to the first marginal portion 51. More precisely, the first and second walls 521 and 522 of the second marginal portion 52 are located in a plane parallel to the third wall 513. The third wall 523 of the second marginal portion 52 is located in a parallel plane to the first and second walls 511 and 512. The fourth wall 524 of the second marginal portion 52 is parallel to the fourth wall 514 or, advantageously, can be coplanar. The fourth wall 524 is parallel to the bottom panel 2 and the first, second and third walls 521, 522 and 523 are perpendicular. In the ordinary direction of use of the stackable tray 1, the first, second and third walls 521, 522 and 523 are vertical and the fourth wall 524 is horizontal.
    The central portion 53 has, in a view from above, see Figure 5, a polygonal shape, at this point, pentagonal. The central portion 53 is symmetrical with respect to a plane passing through the bisector of the angle formed between the plane of the first wall 511 and the plane of the first wall 521 of the first and second marginal portions 51 and 52, respectively. The central portion 53 can also be symmetrical with respect to the plane passing through the fourth walls 514 and 524 of the first and second marginal portions 51 and 52.
    The central portion 53 comprises a first wall 531 parallel to the third wall 513 of the first marginal portion 51. The first wall 531 passes to close the U determined by the first, second and third walls 511, 512 and 513. The first wall 531 it has a width slightly greater than the width of the third wall 513. In this way, the first wall 531 of the central portion 53 is configured in relief in relation to the first wall 511 and in relation to the second wall 512. Said projections constitute a stop for the pressure coupling of the profiled portion 4 receiving the first marginal portion 51, especially for the larger walls 40 and 41. The first wall 531 of the central portion 53 can also be taller than the second wall 512, offering likewise a stop for the minor walls 42 and 43 of the profiled portion 4. The first wall 531 of the central portion 53 extends beyond the free upper end of the first and second walls. 511 and 512 of the first marginal portion 51.
    The central portion 53 comprises a second wall 532 attached to the second marginal portion 52. The second wall 532 is symmetrical with respect to the first wall 531. The

    second wall 532 determines a stop for another profiled portion 4 pressurized in the second marginal portion 52. The central portion 53 comprises a third portion 533 disposed substantially at 45 ° with respect to the first and second walls 531 and 532. The third wall 533 is normal to that bisector. The third wall 533 is located within the concavity determined by the first and second marginal portions 51 and 52, see Figure 5. The third portion 533 has a relatively small width, advantageously less than 10 mm. The third wall 533 joins the first and second walls 531 and 532.
    As a variant, the third wall 533 could be replaced by a direct right angle link between the first and second walls 531 and 532. In another variant, the third wall 533 is replaced by two perpendicular walls, each perpendicular to the walls. first and second 531 and 532 in order to free up the maximum space of the tray. The two perpendicular walls form an incoming angle.
    The central portion 53 comprises a fourth wall 534 parallel to the fourth walls 514 and 524 of the respective first and second marginal portions 51 and 52 or advantageously coplanar with said fourth walls 514 and 524. The fourth wall 534 determines a tie that stiffens the others walls of the central portion 53, especially compression, tension, torsion, buckling, shearing.
    The central portion 53 comprises a fifth and sixth walls 535 and 536 symmetrical in relation to the plane passing through said bisector. The fifth wall 535 is parallel to the first and second walls 511 and 512 of the first marginal portion 51. The sixth wall 536 is parallel to the first and second walls 521 and 522 of the second marginal portion 52. The fifth wall 535 is joined perpendicular to the first wall 531 of the first marginal portion 51 on the side opposite the third wall 533. The sixth wall 536 is perpendicularly attached to the second wall 532 of the second marginal portion 52 on the side opposite to the third wall 533. The fifth wall 535 is a neighbor of the second wall 512 of the first marginal portion 51. The sixth wall 536 is a neighbor of the second wall 522 of the second marginal portion 52. The fifth and sixth walls 535 and 536 are less than the width width of the first wall 531. The fifth and sixth walls 535 and 536 are of width greater than the width of the third wall 533.
    The fifth and sixth walls 535 and 536 are joined by a seventh wall 537 arranged at the bias. The seventh wall 537 is advantageously parallel to the third wall 533. The seventh wall 537 is wider than the width of the first wall 531. The seventh wall 537 determines an outer wall of the central portion 53 in reference to the tray

    stackable 1. The central portion 53 has a height substantially constant by its contour.
    In the ordinary direction of use of the stackable tray 1, the first, second, third, fifth, sixth and seventh walls 531, 532, 533, 535, 536 and 537 are vertical and the fourth wall 534 is horizontal. In other words, the fourth wall 534 is parallel to the bottom panel 2 and the other walls are perpendicular.
    The pentagonal shape of the central portion 53 offers a very small space occupation on the inside of the tray, a release of volume from the outside of the tray, a good rigidity along a vertical axis, but also along the axis main horizontal of the first marginal portion 51 and the main horizontal axis of the second marginal portion 52. The central pentagonal portion 53 also offers good torsional strength, especially torsion of the first marginal portion 51 relative to the second marginal portion 52 The corner 5 can be manufactured by molding, offering a simple position of the fourth horizontal walls 514, 524 and 534. Corner 5 can be made of synthetic material. Wall thicknesses can be substantially constant and equal.
    The assembly of the container can be carried out by pressure coupling of two corners 5 at the ends of a first profiled portion 4, pressure coupling of two opposite corners 5 at a second profiled portion 4 opposite, insertion of the bottom panel 2 into the groove 47 of the first profiled portion 4 equipped with the two corners 5, insertion of the groove 47 of two other profiled portions 4 and pressure engagement of each of said two profiled portions 4 in the free marginal portion of each corner 5 associated with the first profiled portion 4 that has already received the bottom panel 2, pressure coupling of the free marginal portions of the corners 5 snapped in the second profiled portion 4 at the free end of the other two profiled portions and, therein translation movement, insertion of the last free edge of the bottom panel 2 into the groove 47 of said second profiled portion 4.
    In this way, each edge of the bottom panel 2 is housed in the groove 47 of one of the profiled portions 4. In truncation of the angles of the bottom panel 2 it corresponds in shape to the corners 5, a slight play may remain between said truncation and the third wall 533 of the central portion 53 of the corners 5. The profiled portions 4 are distant from each other. Two contoured portions 4 neighbors are separated by the central portion of the corners 5.
    Next, the four profiled portions are welded onto the bottom panel. Welding can be done by heating the synthetic material. The corners 5 then become non-removable and, with the profiled portions 4 and the bottom panel 2, take care of the stiffness of the container.
    5 In a manner not shown in the drawings, at least one coinage python can go
    disposed on the bottom panel 2, remote from the flange 3 and from the side of the bottom panel 2 where the flange 3 is located. Said at least one wedge python is heat welded to the bottom panel 2. The wedge python flush with the upper surface of the profiled portions 4 of the flange 3. The wedge python decreases the 10-fold of the bottom panel 2 at a distance from the flange 3, especially in load. The minting python increases the load that can be transported in the device. The minting python can be made of the same material as corners 5. The minting python can be made by molding and have a hollow shape with walls of substantially constant thickness. The wedge python can be shaped like a cylinder 15 closed at one end and opened at the opposite end. The minting python
    It can be welded to bottom panel 2, especially heat-welded. A line of wedges can be arranged parallel to the major sides of flange 3.
