Definitions

  • the box of the present invention is a high-performance packaging solution for the transport and storage of bulky material, such as granulated products, powdered products, etc.
  • the box of the present invention is based on an octagonal prismatic-type tubular structure that is inserted in a base novelty formed by two identical elements which, when superimposed crosswise with an element, make it possible to block the base by means of counter pressure.
  • the object of the invention is to provide a box whose base is structurally simpler than that of conventional boxes of this type, improving the manufacturing and assembly process, which are substantially simplified, in addition to making it possible to save in the volume of material used without affecting the resistance of the box, which will respond to market needs.
  • the box be easily folded once unfolded in order to facilitate the reuse thereof.
  • Boxes made of corrugated cardboard and/or composite materials are widely used in the fruit and vegetable industry and in other non-food industries but have a series of drawbacks related, in general, to the fact that the production process requires considerable amounts of raw material with large amounts of cardboard that is disposed of as waste for the purpose of producing the reinforced corners, especially on the faces of the smaller sides or faces of the larger sides of the box.
  • Another drawback is that a box made of cardboard and/or composite materials is often supplied as a flat matrix difficult to assemble.
  • pre-assembled cardboard and/or composite material boxes of the type known are difficult to unfold and return to their flat state, necessary to facilitate storage in preparation for reuse or for recycling operations or for destruction prior to their disposal as waste.
  • French patent FR-A-2236738 discloses a single-piece cardboard box formed from a matrix having a base panel, lateral and end wall panels, corner connection panels that intersect edges which are fixed, respectively, to an lateral and end wall panel, a blocking panel joined to, at least, one of the connection panels on each of the ends of the cardboard box and, optionally, one or more upper panels.
  • the connection panels have a diagonal folding line that divides the panel into a first triangular reinforcement section fixed to an end wall panel and a second triangular reinforcement section fixed to a lateral wall panel.
  • the blocking panel is joined to the second triangular section of the connection panel.
  • each connection panel In the assembled cardboard box, the triangular sections of each connection panel are folded in front contact and disposed along the exterior of the end wall panel with the triangular section sandwiched between the end wall panel and the second triangular section.
  • the blocking panel extends over the upper edge of the first triangular section and the end wall panel in the interior of the cardboard box, wherein it is fixed in front contact with the inner surface of the end wall panel to maintain the cardboard box in the assembled position.
  • Utility model application U201500584 reveals a box having an octagonal prism configuration with two larger faces, two smaller faces alternated with the foregoing and another four smaller faces, forming what can be considered four bevels between the smaller and larger faces.
  • the box has, in correspondence with one of its edges, cutting and folding lines that make it possible to form the base, since the box in question is envisaged to be arranged on a pallet or a surface that will act as part of the base thereof, said base having two larger lateral flaps and another two smaller flaps, the latter having an intermediate and central cutting line that results in two oblique cutting lines, forming a trapezoidal base reinforcement, while the aforementioned larger extensions have oblique folding lines, forming triangles which in one case are attached to the inner side of the smaller sectors and, in another case, are attached to the outer side thereof.
  • the box is obtained from the development of a rectangular sheet of cardboard having transversal folding lines to delimit sectors that will form eight faces that define the lateral surface of the box, said box having an octagon shape, defining two sectors (1) or larger walls, two sectors or intermediate walls (2) alternated with the former and between both sectors (1) and (2) four smaller sectors (3) determining bevels that form the octagonal shape of the box.
  • Utility model application U200900797 is based on conventional octagons, specifically two octagons and consists of incorporating an octagonal prismatic tubular body in the box, which is inserted by its lower end in the similarly lower octagon and which is similarly closed by its upper end with the collaboration of the second octagon, by way of a lid.
  • the base of this box is formed from a cardboard piece having a plurality of cuts forming flaps and which, when vertically folded, generate a cavity wherein the octagonal prismatic tubular body is inserted.
  • One of the problems caused by this type of box is that a large amount of material is lost in the manufacture of the base due to the cuts made in the structure that gives rise to the base, in addition to the fact that whenever it is transported the whole structure must be reassembled.
  • Patent ES 2230182T discloses a folding container, preferably made of corrugated cardboard which, although envisaging different embodiments in accordance with the even number of sides of its base, its octagon base variant is obtained from four independent pieces which are joined together by means of complementary slots defining curved sectors which, when assembled, are partially superimposed therebetween.
  • a folding receptacle having an octagonal prism configuration wherein the base consists of two identical dovetailed pieces, such that the two identical base pieces have a semi-octagon configuration with an intermediate folding line and wherein the four sides of the semi-octagon extend, after the corresponding folding lines, into four flaps, two of which are adjacent and of greater height than the two end flaps, such that one of these flaps of greater intermediate height has an end fixing tab for fixing the other flap, by gluing therebetween, when the orthogonal offset of said flap with respect to the sectors defined on either side of the intermediate folding line of each of the semi-octagon pieces is carried out.
  • both the flaps of lower height and the flaps of greater height are fixed during the assembly of the two base pieces to the inner lateral surface of the walls of the tubular-shaped octagonal body, while a cut-out of angular configuration is established in correspondence with one of the ends of the intermediate folding line of the two base pieces for dovetailing the two pieces, whereupon the extensions resulting on either side of the cut-outs are delimited by an imaginary line transversal to the intermediate folding line, alternately overlapping each other.
  • the box of the present invention has the novelty that its base is formed exclusively from two identical elements which, when superimposed crosswise, making it possible to block the base by means of counter pressure by performing a simple manoeuvre, guaranteeing the structural rigidity of said base.
  • the sides can be folded downwards, reinforcing the base and preventing that, upon introducing the belt-type structure, it folds inwards obtaining a highly resistant box that does not require additional elements to support the lateral reinforcements to which its walls are subjected when loaded with products such as melons, potatoes, etc., regardless of the self-assembly process of the box in question, due to which a box is obtained that is reinforced to reduce the lateral sagging or bending caused by the product it contains, thereby addressing the problems and drawbacks of conventional boxes of this type.
  • the box can be easily transported, since the base can be folded over the base centre, causing the entire structure to fold inwards; therefore, it is not necessary to assemble the complete structure each time it is transported, since it would be sufficient to unfold the box again from the base centre (50) when necessary, thereby obtaining the box. In this manner the box occupies the least amount of space for storage and transport.
  • the box of the invention incorporates additional flaps to the constituent elements of the base, which makes it possible to maintain the other flaps in an upright position, resting on the outer lateral surface when two of said base elements are superimposed crosswise, said elements additionally containing a small flap that confers greater rigidity to the octagon, such that the lateral surfaces of the prism do not collapse towards the vertical axis of symmetry of said prism and the lateral surface is not folded inwards.
  • the fold formed by the vertical edges of the octagon confer the desired rigidity to the assembly that would not be achieved with a prism with fewer faces.
  • the new flaps, on sliding over the lateral surfaces, confer greater rigidity to the base, keeping it flat.
  • the box of the present invention is a high-performance packaging solution for the transport and storage of bulky material, such as granulated, powdered or loose products; the box is made of high-performance corrugated cardboard and can be assembled manually and is also a profitable and environmentally friendly alternative to wooden or metal crates.
  • the box of the present invention is a high-performance packaging solution for the transport and storage of bulky material and does not require additional elements to bear the lateral stresses to which its walls are subjected when loaded with products such as melons, potatoes, etc.
  • the base of the box is formed from two identical semi-tray shaped base elements (1) glued in two places to the outer perimeter of the octagonal central body with the aid of flaps.
  • Each of these components is equipped with a bellows system that makes it possible to fold inwards in order to limit the space.
  • the crosswise assembly of these two elements makes it possible to guarantee the assembly and maintenance of the base by means of a counter pressure system.
  • the sides (7) can be folded downwards, reinforcing the base and preventing the octagonal prismatic tubular body (2) from folding in on itself when introduced. This assembly allows the user, when deploying the belt, to automatically form the base without additional components.
  • each base element (1) has been envisaged to incorporate an additional flap (70) which, when coupled to another similar base element (1) in opposition thereto, generates two lateral walls resting on the corresponding outer lateral surface of the octagonal prism and reinforce the vertical of the base when the octagonal prismatic tubular body (2) is inserted.
  • Said base element (1) also incorporates an additional second flap (80) smaller than flap (70) that gives the octagon greater rigidity, such that the lateral surfaces of the prism do not collapse towards the vertical axis of symmetry of said prism and the lateral surface does not fold inwards.
  • the box of the present embodiment is formed from the joining of two identical base elements (1) that form the base and have the shape observed in figure 1 and the insertion of an octagonal prismatic tubular body (2), which is inserted in the result of superimposing the base element (1) with another similar element crosswise.
  • the base elements (1) that form the base as a result of the angle between flap (10) and flap (20) allow them to fold inwards over the folding lines (3) and (4).
  • Each base element (1) that makes it possible to form the base of the box has the intersection of two curved ends (8) and (9) in the coupling zone, whose elliptical curve shape allows element (8) to be assembled on top of element (9) at point (60) and, therefore, when coupled with another base element (1) are resistantly fixed upon forming the base of the box.
  • Flaps (30) and (40) are identical symmetrical images with respect to an axis that passes through the joining point between flaps (10) and (20) and are folded inwards over the folding lines (5) and (6).
  • the flaps are folded upwards along the folding lines (3), (4), (5) and (6) forming 90-degree angles with respect to the lower plane, four adjacent vertical planes formed by means of flaps (10), (20), (30) and (40) are generated, wherein the height of these vertical planes is the same dimensions as the width of said flaps.
  • the joining point between end sides (8) and (9) produce a central point (50) which, when superimposed crosswise with a second element (1) make it possible to form the base of the box, since it is blocked by means of counter pressure.
  • sides (7) and (7') can be folded downwards, reinforcing the base and preventing the octagonal prismatic tubular body (2) from folding in on itself when introduced.
  • the octagonal prismatic tubular body (2) is formed from a sheet of cardboard originally open and folded in the shape of a rectangular parallelepiped, wherein one of the upper ends is folded diagonally, (a) forming a prismatic tubular structure (b) which can be completely folded (c) generating a series of six-sided pre-folds (d) and (e), as can be observed in figure 4 .
  • flaps (10) and (20) are fixed to the inner surface of the octagonal prismatic tubular body (2), while flaps (30) and (40) are fixed externally to said body.
  • Each base element (1) incorporates a flap (70) which is folded along the folding line (7') at a 90-degree angle and which, when the element is coupled (1) to another similar element in opposition thereto, gives rise to two external lateral walls that rest on the corresponding lateral surface of the octagonal prism and reinforce the vertical of the base when the octagonal prismatic tubular body is inserted (2).
  • the base element (1) incorporates a flap (80) smaller in size than flap (70) that is folded along the folding line (8') at a 90-degree angle and which, when superimposed crosswise with another similar base element (1), generates two internal lateral walls that make it possible to confer greater rigidity to the octagon, such that the lateral surfaces of the prism do not collapse toward the vertical axis of symmetry of said prism and the lateral surface is not folded inwards.
  • the joining point of ends (9') and (11) produce a central point (50) which, when superimposed crosswise with a similar second base element (1), enable them to fit around said central point (50) forming the base of the box, since it is blocked by means of counter pressure.
  • the octagonal prismatic tubular body (2) is formed in the same manner as in the example of figures 4 and 5 , adapting regular octagons, i.e. with eight sides of identical size, but said body may also form irregular octagonal prisms such that there are two opposite sides of identical dimension, each separated by three sides (a total of six sides) of another identical dimension, such as to form an irregular octagonal prism initially having two identical sides parallel to another three identical sides between the aforementioned initial sides.
  • the box can be easily transported, since the base can be folded over the central point (50) of the base, causing the entire structure to fold inwards; therefore, it is not necessary to assemble the complete structure each time it is transported, since it would be sufficient to unfold the box again from the central point of the base (50) when necessary, thereby obtaining the complete box; in this manner the box occupies the least amount of space for storage and transport.
  • the box of the present invention is a high-performance packaging solution for the transport and storage of bulky material, such as granulated, powdered or loose products; the box is manufactured with high-performance corrugated cardboard and can be assembled manually and is also a profitable and environmentally friendly alternative to wooden or metal crates.
