Definitions

  • This invention relates to a cardboard precut blank and a cardboard platform obtained from the precut blank.
  • the invention relates to the sector of goods loading and transport, and in particular to the cardboard platforms and the so-called Palboxes, which have started to become widespread over recent years due to both environmental and economic reasons.
  • platforms also called loading pallets or simply pallets, that is to say, portable platforms, generally made of wood and consisting of spaced rectangular strips, overlying slats which are also spaced apart in such a way as to allow the insertion of the horizontal arms of the forklift trucks with which the platforms are lifted and moved.
  • platforms made of cardboard have been proposed, which have the advantage of being much lighter than wooden platforms, for the same weight supported, and they can be assembled at the time of use and dismantled for the rest of the time, with a considerable saving in transport and storage space.
  • the cardboard platforms can be integrated with a box-shaped structure made of cardboard, to form the base of a so-called Palbox, that is, a large sized container for the transport and display of goods.
  • Palbox a so-called container for the transport and display of goods.
  • a limitation of the cardboard platforms which are currently available on the market consists in the difficulty in assembly and insertion in the Palbox, especially in terms of the time needed for the assembly, and consequently in terms of cost.
  • the aim of this invention is to provide a cardboard precut blank and a cardboard platform obtained by means of the precut blank which can offer to the user simplicity and very fast speed in the assembly and insertion in a Palbox.
  • the reduced assembly times increase the quantity of platforms made in the same time and, consequently, reduce the costs.
  • the main aim of the invention is to provide the final user with a very robust product, which is able to offer a considerable strength in terms of compression.
  • Another characteristic which substantially differentiates the cardboard precut blank and the cardboard platform obtained by means of the precut blank according to this invention is the absence of adhesive tape for the assembly and the blocking of the structure of the platform, which is consequently configured as a totally recyclable product.
  • the aim of this invention is therefore to provide a cardboard precut blank and a cardboard platform obtained by means of the precut blank which allows the limitations of the load platforms according to prior art technology to be overcome and to obtain the technical results described above.
  • a further aim of the invention is that the cardboard precut blank and the cardboard platform obtained by means of the precut blank can be made with substantially reduced costs, both in terms of the production costs and with regard to the management costs.

  • the precut blank can comprise a second sub-panel made in the central part at the second perimeter line, the precut blank being configured in such a way that when the precut blank is assembled as a platform, bending upstream, with respect to the outer face of the precut blank, the second sub-panel along the respective perimeter line it forms a supporting surface for the first sub-panel.
  • the first sub-panel when the precut blank is assembled as a platform the first sub-panel may be coupled to the second subpanel, in particular by gluing.
  • the overall length of one or two sub-panels can be less than the length of the two cut lines, in such a way as to leave an empty space in the central part.
  • the first panel and the third panel can comprise, on the respective left sides, a first left shaped panel and a second left shaped panel, and on the respective right sides, a first right shaped panel and a second right shaped panel, in such a way that when the precut blank is assembled as a platform, bending upstream, with respect to the outer face, the first left shaped panel and the second left shaped panel, along the respective crease lines the first right shaped panel and the second right shaped panel engage with each other, in such a way that the first, second and third panel block with each other at right angles and with respect to the central panel.
  • the first shaped panels each can have a lateral tab divided by a crease line parallel to the third crease lines, designed to enclose in the leg of the platform when the precut blank is assembled as a platform.
  • the precut blank can comprise a second left lateral shaped panel and a second right lateral shaped panel at a third or first panel, in such a way that bending downstream, with respect to the outer face, the second lateral shaped panels of a shaped portion along the respective third crease lines, they engage with the other shaped portion, further reinforcing the platform.

  • the protrusion engages in the slot
  • the precut blank can comprise a pair of notches and tabs which are able to engage with each other to facilitate the blocking of the lateral shaped panels when the precut blank is assembled as a platform.

  • other uses of the platform can be contemplated without thereby departing from the scope of protection offered by the invention.
  • the precut blank 1 can be obtained from a single flat sheet, in particular made of paper material, and more specifically made of cardboard, but it is obvious that the same precut blank may allow the same space saving and ease of recycling results to be also achieved if it is made of plastic material or other recyclable material, the main characteristics of which being that of allowing a fast assembly and not requiring the use of aids for the assembly, which might be made of different material (such as, for example, the adhesive tape necessary for the prior art cardboard platforms to ensure the assembly).
  • the flat precut blank 1 of Figure 1 comprises a plurality of fold lines or crease lines designed to be bent to obtain the platform shown in Figures 4 and 5 .
