Definitions

  • the present invention concerns a support for handling loads of the type known as pallet or portable platform, made of corrugated cardboard, as well as a process for the production thereof.
  • Pallets of corrugated board have been known for some time: these products have been developed to solve the problems arising in connection with wood pallets. In fact, though wood palletts were designed to be used for several times, today, due to logistic problems related to storage and recovery, they are generally used only once, thus leaving the problem of their disposal.
  • An object of the present invention is therefore that of providing a pallet made of corrugated cardboard capable of solving the aforesaid problems of resistance and rigidity by way of a simple and economic structure.
  • a further object of the invention is to provide a process to produce a cardboard pallet in an easy and economic way. Said objects are achieved by means of the present invention that concerns a pallet for handling loads, of the type consisting of a plurality of elements of corrugated cardboard, characterized in that it comprises two or more superimposed blanks of corrugated cardboard, each blank being provided with a plurality of die-cut flaps bent in a same direction substantially normal to the plane surface of said blanks, said flaps being positioned in correspondence to the flaps of the upper and/or lower blank and cooperating therewith and with a plurality of elements holding said folded flaps in position to form a plurality of supporting feet for the pallet, and in that the corrugations of the folded flaps cardboard are normal to the plane of said blanks.
  • the invention also concerns a process for the production of a corrugated cardboard pallet or similar support for handling loads, characterized in that it comprises the following steps: die-cutting a plurality of blanks of corrugated cardboard and providing on each blank a plurality of foldable flaps; superimposing at least two of said blanks, with said flaps at least partly overlapping each other; folding the flaps normally to said blanks plane, on the same side, the direction of each folded flap corrugation being normal to the plane of said blanks; applying a multiplicity of holding elements keeping said folded flaps normally to the blanks and forming a plurality of supporting feet for said pallets.
  • the holding elements coooperating with the folded flaps to form the supporting feet of the pallet also serve as reinforcing elements and are consisted of cardboard boxes positioned inside and/or outside the projecting structure formed by the folded flaps.
  • the size of the thus formed feet is larger than the average distance between the axes of two adjacent rollers in a known roller conveyor, thus enabling moving the pallet on said currently available roller conveyors, Said feet are moreover spaced from each other of a length sufficient to house the forks of pallets handling equipment.
  • the feet are also dimensioned in a way that those of one pallet can be housed in the spaces provided for the above cited forks in a second -upturned-pallet and this in order to save space during transporation and storage, by suitably superimposing the formed pallets.
  • Figure 1 shows two die-cut blanks, 1 and 2, of corrugated cardboard which are forming the surface or loading base of the pallet itself.
  • Each blank is provided with a plurality of die-cut flaps 3 which, as shown in the following figures 2 and 3, once the pallet is formed, are folded in the same direction, forming a substantially right angle with the level of the relevant blank.
  • flaps 3 are die-cut in a way that their free end 4 is substantially perpendicular to the direction of the corrugation axis (i.e. to the axis of the wrinkles - or alternated ridges and grooves) of the relevant blank of corrugated cardboard, direction shown by arrow F in figures 1, 5 and 8.
  • the corrugation of the folded flaps will thus result substantially perpendicular to the loading surface represented by blanks 1 and 2.
  • the pallet resistance is furtherly increased by coupling the continuous cardboard blanks with their respective waves perpendicular to each other, as shown in figures 1 and 8.
  • the flaps 3 are die-cut in couples on blanks 1 and 2 in a way that, when superimposing the two blanks, they are positioned in correspondence to each other and normal to one another.
  • the free sides 4 of the flaps on one blank must be substantially perpendicular to the sides 4 of the flaps of the other, upper or lower, blank.
  • the so folded flaps preferably provide a parallelepiped structure, as shown in figure 3 or, alternatively, a very slightly truncated-cone structure to allow at least part of a foot to be housed into the corresponding structure of the underlying pallet in a pile of superimposed pallets.
  • FIG 6 are shown two blanks, 1a and 2a, of corrugated cardboard having "S" shaped flaps 3a.
  • flaps 3a shape is the only difference from blanks 3 of previously disclosed figures 1-3: all other features are identical and apply to this embodiment and, namely, the perpendicularity requirements of free sides 4 of flaps 3a with respect to the corrugation axes are met.
  • flaps 3 are provided with positioning elements to keep them in the desired position, namely perpendicular to the level of blanks 1 and 2. Said positioning elements may consist of small tongues 8 and slots 9 arranged in a complementary way on flaps 3 (figure 5), or alternatively of other elements designed for that purpose.
  • the pallet supporting feet i.e. the projecting structures p formed by the folded flaps cooperate with a corresponding plurality of holding elements which also serve as strengthening elements.
  • Said strengthening elements may be made of any material suitable therefor, but preferably consist of corrugated carboard boxes.
  • Said boxes 5, 5' (fig. 2) are positionable inside and/or outside the projecting structure P formed by the folded flaps 3 and are preferably secured to said flaps and/or to the plane surface of the blanks, thus contributing to hold in position flaps 3 and to form the pallet supporting feet.
  • Figure 5 shows a magnified perspective view, in partial section, of a finished pallet foot according to the invention.
  • the supporting feet comprise four flaps 3 each, die-cut from two superimposed blanks 1 and 2, and folded downward of said blanks and forming a right angle therewith.
  • the feet are also provided with a box 5 serving as holding and strengthening element, housed inside the structure formed by the folded flaps, and with a second box 5' positioned outside said flaps and having the same functions as box 5.
  • FIG 8 is depicted an exploded view similar to above cited figure 5, the flaps 3a being the "S" shaped ones disclosed with reference to figure 6. Because of the shape of flaps 3a, each "wall" of structure P formed by the folded flaps has a missing area 9.
  • the preferred arrangement shown in figure 8 provides for an alternated position of said area 9, i.e. a "flap 3a - area 9 - flap 3a - area 9" disposition.
  • the other possible combination having two couples of flaps 3a adjacent and forming two corners, can be used.
  • the corrugated cardboard from which blanks 1 and 2 are made is preferably of the double type, while the reinforcing elements, namely boxes 5 and 5,' are made of simple type corrugated cardboard.
  • the size of the pallet supporting feet is greater than the distance between two adjacent rollers, that is, the distance between the axes of two adjacent rollers in a roller conveyor of the type currently used for handling loaded pallets, so as to ensure an easy moving on said conveyors of the pallets according to the invention.
  • the feet height and their reciprocal arrangement are such as to allow the forks of pallet handling devices, such as transpallets and the like, to be housed therebetween, as well as to allow the feet of another pallet to be housed, updown, therebetween in a space-saving disposition, to facilitate the pallets transportation and storage.
  • aforedescribed pallets takes place according to the following steps: at first a plurality of corrugated carboard blanks are die-cut providing a plurality of foldable flaps on each blank.
  • the flaps are die-cut with their free side normal to the direction of the corrugation of its cardboard blank, so that once folded the direction of the corrugation is substantially parallel to that of the combined bending and compressing stresses, i.e. it is substantially perpendicular to the plane of blanks 1 and 2.
  • the flaps are die-cut in opposed couples and two die-cut blanks are superimposed in which the overlapping flaps are perpendicular to each other.
  • each foot will comprise four flaps cooperating with said holding-positioning and strengthening elements.
