Definitions

  • the invention relates to an insulating complex and its method of production.
  • the invention relates to the technical sector of packaging without excluding other areas of applications, such as sound insulation.
  • the polyurethane has open cells so that the product obtained is not rigid, and therefore does not hold the load.
  • this type of product is generally used to produce, for example, packaging of small boxes, but is most often used to make mattresses.
  • the problem to be solved by the invention is to provide a packaging product sufficiently rigid to hold the load with the objective of distributing the load uniformly and significantly reducing the amount of material used without reducing the rigidity of the product.
  • thermoset material foam board which has a series of recessed and raised forms alternately constituting male parts and female parts.
  • complementary capable of allowing overlapping, in superposition, with another complementary complex so as to form a compact set of full section and quadrangular.
  • the foam may be polyethylene (PE), polypropylene (PP) or polyester (PET).
  • PE polyethylene
  • PP polypropylene
  • PET polyester
  • a foam plate having a quadrangular cross section with a thickness of between 10 and 500 mm is used,
  • a section is made by means of a profiled blade to produce two parts adapted to create, after separation, a series of recessed and raised forms alternately constituting male parts and female parts to obtain two imbricable insulating complexes. It follows therefore from these characteristics that it is possible to produce from a plate of a given thickness two identical and symmetrical detachable products, instead of one, following the formation of the hollow and raised forms. It should be noted that the hollow and raised forms make it possible to improve the resistance to the load and to distribute it.
  • the blade is moved linearly in the direction of the length of the plate which is fixed or vice versa.
  • the blade is heated to a temperature of between 60 and 130 ° C.
  • Another technical problem to be solved by the invention is not only to provide an insulating complex which holds the load with a minimum of material but also to be able to shape the complex if necessary by considering the relative rigidity of the foam used.
  • the recessed and raised forms are made from a planar zone, the thickness of which, considered to be in the form of recessed shapes, is very small compared with the depth of said recessed shapes.
  • the recessed and raised forms are symmetrical and may be of rounded cross section forming a sinusoid or trapezoidal cross section without excluding other geometric shapes. Note that these recessed and raised forms are parallel to each other and to the edge of the plate or may be oriented differently relative to the longitudinal edges of the plate. They can be rectilinear or not.
  • Figure 1 is a cross-sectional view of a foam plate subjected, in its thickness, to a cutting operation for producing two symmetrical and identical parts in order to produce two insulating complexes after separation of said parts.
  • FIG. 2 is a view corresponding to FIG. 1 showing the separation of the two parts of the plate resulting from the cutting operation
  • FIGS. 3 and 4 are views respectively corresponding to FIGS. 1 and 2, of another form. resulting embodiment of the profile of the cutting blade.
  • FIG. 5 is a perspective view of the insulating complex.
  • Figure 6 is a sectional view of an alternative embodiment of the insulating complex.
  • the insulating complex according to the invention is made from a plate (1) made of PE, PP or PET foam.
  • the thickness (E) of the plate (1) is determined according to the type of packaged product and corresponding to thicknesses commonly used in the field of packaging from a particular PE foam.
  • a section (2) is produced in the middle part of the thickness of the plate (1) by means of a profiled blade.
  • the blade is profiled to produce two identical parts (la) and (lb) able to create, after separation, a series of recessed and raised forms alternately constituting male parts (a) and female parts (b).
  • the blade is moved linearly in the direction of the length of the plate (1) which is fixed without, for this, exclude a reverse process, namely, that it is the plate (1) which is movable relative to the blade which is fixed. Note that to perform the cutting operation, the blade is heated to a temperature between 60 and 130 ° C.
  • the insulating complex resulting from this cutting operation, has hollow and raised forms (a) and (b) made from a flat area (c).
  • the thickness of this planar zone (c) considered at the right of the recessed shapes (b) is very small compared to the depth of said recessed shapes.
  • the zone (c) may be of the order of 5 mm.
  • Two insulating complexes are thus obtained instead of one having the same load-bearing characteristics, which are, moreover, improved with regard to the formation of the recessed and raised zones.
  • hollow and raised forms are symmetrical and can have different profiles in cross section.
  • Figures 1 and 2 the recessed and raised forms are of rounded cross section forming a sinusoid.
  • the recessed and raised forms are of trapezoidal cross section.
  • the various recessed and raised shapes may be parallel to each other and to the longitudinal edges of the plate or be oriented angularly with respect to the edge of the plate. Similarly, they can be rectilinear or not.
  • stiffness plate (3) which can also be made of PE foam and which will be of a density higher than the density of the PE foam used to realize the shape of the complex.
  • the density of the plate (1) from which are made the insulating complexes according to the invention is between 10 and 150 kg per cubic meter.
  • the plate has a thickness of between 10 and 500 mm approximately.
  • the recessed and raised shapes have arrangements for providing a clipping function in the nesting position.
