Definitions

  • the invention relates to a container made of foldable material so that it can be stored flat and in stack, and more particularly a container likely to take a prismatic shape and to be made of corrugated cardboard.
  • Containers used in industry for transport and storage of various products are indeed made by flat cutting in cardboard plates corrugated preferably multi-groove to be able have good mechanical resistance. Also for for reasons of robustness, these containers have a side wall having flat faces delimited by vertical edges when intended to contain products likely to cause creep important, and so a polygonal base, for example hexagonal or octagonal.
  • Such containers can have a larger capacity per cubic meter and be filled with granular products, or even powdered or liquid if filled inside of a bag made of waterproof flexible material, by plastic example known in the art under the name of "know".
  • the invention aims to create such a container whose bottom and side wall (or mantle, or belt) are cut from a plate for example of corrugated cardboard and pre-assembled by gluing or other factory, and which is foldable so that it can be delivered and stored pre-assembled and flat, the bottom being cut and grooved in a special way so that the container can be quickly set up.
  • the invention relates to a container in foldable material, having a side wall extending continuously and having at least two folds, and a bottom secured to the side wall, characterized in that the side wall and the bottom are joined together to the other in two separate solidarity regions, of the container, in that the container is deformable between a shopping position in which it has a generally flat shape and use position in which the bottom and the side wall define a filling volume, and in that in the position of shopping, the side wall is folded to form two side wall parts connected by the two folds, and the bottom is inserted between the two parts of side wall by being folded in accordion, forming at minus four flaps succeeding one part of the wall side to side by being connected by folds, one end flap of the bottom being secured to one of the side wall parts by a flap, and a flap opposite end of the bottom being secured to the other side wall part by another flap.
  • the container made of foldable material for example corrugated cardboard, shown in the drawings, has a side wall A and a bottom B secured to each other in two separate joining regions, container, and is deformable between a position of shopping in which it has a general shape flat ( Figure 1) and a position of use in which the bottom and the side wall define a filling volume.
  • the side wall A extends continuously, and, in "folded container” position, ie in position of shopping, it is folded so as to present a flat shape in two parts A1, A2 approximately superimposed planes connected by two folds 1.
  • the side wall in position of use, is defined by the translation parallel to itself of a generator whose direction is perpendicular to the background, then plane, whose outline serves as a basis for the translation of this generator; so in the position of shopping, the two sides A1, A2 of side wall are rectangular, and the two folds 1 constitute opposite parallel edges of these two wall parts lateral.
  • the two side wall parts may have lines of folding 2 in succession between the two end folds.
  • the flaps 3 extending on either side fold lines 2 are then in the same plane, and no fold corresponds to fold lines 2.
  • the number fold lines 2 and their mutual spacing and by compared to the end folds 1 depend on the shape of the background.
  • each side wall part A1, A2 has three intermediate 2 fold lines parallel to the two end folds 1, and thus, in position of use, the side wall A has eight folds and has an eight-sided prismatic shape side.
  • the bottom B has a contour corresponding to the desired container shape; here it is a polygon convex with an even number of sides.
  • the polygon examples shown in the drawings is an octagon.
  • this octagon has sides parallel and equal two by two.
  • the bottom B is inserted between the two sides A1, A2 of side wall superimposed by being folded into an accordion, forming minus four successive polygonal panels 4, 5, 6, 7 from one side wall part to the other being connected by folds previously defined by fold lines 8, 9, 10 ( Figures 4 and 5).
  • the joining regions of the wall side and bottom are formed, on the wall lateral, along an edge of two flaps 3 belonging respectively to the two sides A1, A2 of the side wall, and, on the bottom, on two flaps 11 connected by respective folds at the two end flaps 4, 7 respectively ; these respective folds correspond to fold lines 12, 13 extending along sides here parallels of the two polygons constituting the shutters ends 4, 7.
  • connection can be made by gluing or by stapling or another means, a flap 4 end end being thus secured to one of the sides A1 of side wall by a flap 11 arranged outside thereof, and an end flap 7 opposite of the bottom being secured to the other part A2 of side wall by another flap 11 also arranged externally; as these flaps are arranged at the outside of the side wall, the connection of each of them has its end flap by through two parallel folds to account the thickness of the side wall.
  • the edge of the flaps 3 of the side wall along from which the joining region extends is an edge extending between two fold lines or folds, and these respective edges of the two flaps belong naturally to two opposite sides extending between the folds 1, of the two sides of the side wall.
  • the background has the shape of a octagon
  • its successive sections 4, 5, 6, 7, numbering four are connected by three folds (in position of shopping) or fold lines 8, 9, 10 (in position of use).
  • each side of the octagon forming the background corresponds to a fold which, in the position of use of the container, connect the bottom to a flap that applies against the side wall A, two of these flaps being the fastening flaps 11 fixed against the external face of the side wall, while the other flaps 14 do not are not attached to this wall and simply apply against its internal face. Note that the two flaps of securing extend along two sides octagon parallels.
  • the securing flaps 11 can for example be connected to two respectively long sides, to which two other sides equal and parallel to each other are perpendicular; sure these figures, the octagon is therefore writable in a fictitious rectangle whose sides constitute the supports respective four sides of the octagon, and the flaps securing are connected to both sides of large length that extend parallel with the smallest spacing; for convenience, the neighboring region of the intersection of the diagonals and the medians of the rectangle that defines the center 15 of the background, will be in the continuation called "central region of the bottom".
  • the four components 4, 5, 6, 7 at the bottom are therefore defined between the sides of the bottom serving as supports for flaps 11, 14 (here the sides of the octagon), the three fold lines 8, 9, 10 (other than those of the flaps) and the two incisions 16, 17. Note that so general, an incision 16, 17 and the fold line 8, 10 which extends it do not follow one another in a straight line, although it is possible to optimize the geometry of the bottom so that at least one incision and this fold line extend almost linearly or even linearly.
  • Each end flap 4, 7 of the bottom is thus delimited in succession by one side of the bottom which carries a joining flap 11, the incision 16, 17 which starts from this side of the bottom, the fold line 8, 10 which extends the incision to another side of the bottom, and the (two) sides of the bottom that connect this fold line to the side which carries the joining flap (starting side).
  • Each intermediate flap 5, 6 is delimited in succession by a fold line 8, 10 extending a incision 16, 17 to one side of the bottom, the line of folding 9 connecting the two incisions, the other incision 17, 16, and the bottom side connecting this other incision to the fold line 8, 10 start.
  • the end flaps 4, 7 each extend from an edge of a side wall part A1, A2, towards the opposite edge of the same side wall part, up to their fold line 8, 10 common to that of the flaps intermediates 5, 6 which is adjacent; this strand adjacent intermediate extends from this line of folding 8, 10, toward the edge of the wall portion starting side, up to fold line 9 connecting the two incisions, which extends approximately parallel to the edges of the side wall portions.
  • the shape of the flaps is optimized so as not to impede the unfolding of the container or their mutual unfolding, and for this purpose flaps can for example each have a straight edge and a rounded edge.
  • the container shown in Figures 1 to 4 has a background with the shape of an irregular octagon with equal and parallel sides two two, writable in a rectangle whose report lengths of the sides is approximately equal to 1.2.
  • the ratio of the length of the long side of the rectangle, to that of the long side of the octagon, is approximately equal to 2.2, and the ratio of the length of the long side of the rectangle to that of the short side of the octagon about equal to 3.
  • the ratio of the length of the long side of the rectangle, to that of one of the incisions is approximately equal to 4, and the ratio of the length of the same side of the rectangle to that of the other incision is approximately equal to 3.65; finally, the ratio of the length of the long side of the rectangle, at the distance between the end of the incision and the end of the side carrying the securing flap opposite to that from which this incision starts, is about 3.2 for the first incision and 3.5 for the second.
  • Figure 5 shows a container bottom in regular octagon shape; here, a set made up through an incision 17 and a fold line 10 is very markedly broken line, while the other set 16, 8 is almost straight.
  • the ratio of the distance between two sides octagon parallels at the distance from the end of each of the incisions and the side of the octagon belonging to the intermediate flap 5, 6, corresponding is approximately equal to 3.4; the ratio of the distance between two parallel sides of the octagon, at the distance between the end of the incision and closest to the sides of the octagon which are perpendicular to those which border the intermediate flaps 5, 6, is approximately equal to 2.6 for one of the incisions and 3.2 for the other. It is thanks to this asymmetry that the container can be completely folded away for flat storage.
  • the container being initially in the storage position, thanks to external pressure on the two opposite folds of the side wall A or further separation of the wall parts A1, A2 side, we put the container in volume and we cause the unfolding of the bottom B.
  • Maintaining the volume of the container here prismatic with octagonal bottom, is then acquired, and does not no bonding of flaps 14 from the bottom other than the joining flaps 11.
  • the filling participates in addition to maintaining the volume of the container.
  • This container is generally intended to be mounted or placed on a transport pallet, its dimensions are chosen for example according to dimensions of standard pallets (for example a little more 1 m between two parallel sides of the bottom in position of use).
  • the empty container can be flattened for later reuse, or low volume storage and transport by example for elimination, since it can be made of cardboard, a recyclable material par excellence.
  • the invention is not limited to embodiments described above and shown, and we can plan others without going out frame, and in particular to produce containers having a bottom of different shape, with another number of sides.
