Definitions

  • the present invention relates to corrugated cardboard packaging, from a single blank or from several blanks, suitably cut and creased. It relates more particularly to the assembly of parts of walls of these packages, constituted by panels arranged at the ends of the original blank, that is to say the panels of this blank which are not connected together by a line folding.
  • a major drawback of this assembly system is the presence of an extra thickness equal to the thickness of the panels, both inside and outside the packaging.
  • the two panels thus assembled when they lie flat on the same flat support, are not in line with one another, but are offset by a thickness of panel.
  • the flat storage of packaging of this pre-assembled type leads to unstable packaging stacks and, on the other hand, that the mechanized volume setting of these packaging raises various problems.
  • the mechanized introduction of batches of objects to be packaged in this packaging is thwarted by the presence of the extra thickness of the inner leg (s).
  • the presence of at least one connecting tab in excess thickness at the end of the packaging detracts from the appearance of the latter.
  • the grooves are certainly arranged vertically, to ensure good resistance to compression during stacking of the packages, but this technique is naturally not applicable to the assembly of parts of the panels of a package since, as it was indicated above, the corresponding portions of groove and cover of these two parts of panels to be assembled are not brought edge to edge, and that on the contrary a vacuum remains below the protruding part of cover serving assembly tab.
  • the present invention is concerned with this type of assembly system, and it aims to remedy the drawbacks of the prior art by proposing a method which can be implemented using corrugated cardboard of a suitable type tional, which lends itself to the assembly between them of parts of the lateral packaging faces and which allows the realization of packaging in which the corrugated cardboard flutes can be arranged vertically.
  • the subject of the invention is a method of assembling parts of the walls of a package produced from at least one blank, cut and grooved, in conventional corrugated cardboard with at least one layer of grooves, characterized in that one eliminates, along the entire length of the free edge of each of the end panels of the blank, parallel to the grooves of the corrugated cardboard, on the one hand, the contiguous part of one of the cover sheets arranged on the outside of the corrugated cardboard, and, on the other hand, the underlying internal structure thereof, leaving only part of the other external covering sheet to remain, at least at a fraction of said edge, so that '' it overflows forming a strip in the extension of the panel to which it is attached, the cover sheet whose part contiguous to said free edge remains being different for each of said end panels, so that the strips formed by the protruding parts are arranged on either side of the blank, in that the said strips and / or the corresponding parts of the opposite end panel are then glued against which they are intended to be applied,
  • the removal of part of the covering and of the underlying internal structure of the corrugated cardboard, parallel or perpendicular to the grooves can be done using a sharp tool, by a laser beam. , or by any other means known in the art.
  • corrugated cardboard By the term “underlying internal structure of corrugated cardboard”, we naturally designate the single flute in the case of a double-sided corrugated cardboard, the two flutes between which a middle sheet is interposed, in the case of a corrugated cardboard double double, and the three grooves and two middle sheets, in the case of a triple carton.
  • the packaging produced by the method according to the invention and in which the assembly of wall parts is carried out using two connecting strips adjoining one of the panels and glued against the other panel has, of course , a much higher resistance, at the level of this assembly, than that of the usual packaging comprising only one junction tab, because double-sided bonding increases safety! of the junction.
  • This method has, moreover, the advantage of practically causing no extra thickness, outside and inside the package, at the junction tabs. Admittedly, such an assembly method requires the use of cutting tools, but, on the other hand, it does not imply the use of separate joining strips of corrugated cardboard.
  • the grooves of the corrugated cardboard can be parallel to the vertical edges of the packaging and thus ensure that it has optimum resistance to compression.
  • Another object of the invention is therefore constituted by such a packaging from at least one blank of conventional corrugated cardboard, and parts of the same wall corresponding to the end panels of each of the blanks are secured to one another in the same plane by two strips formed by a portion of the external cover of each of said panels, projecting outside the panel to which it is attached and glued against the adjacent panel, one outside of the package and the other inside thereof, the free edges of the grooves underlying said covers being arranged substantially edge to edge and these grooves being substantially parallel to the vertical edges of the mounted packaging.
  • Such packaging is particularly suitable for packaging heavy products, because of the double security provided by the glued tabs on both sides and by the vertical grooves in the corrugated cardboard.
  • This method of assembly also reduces the risk of tearing or unsticking of the strips and it is therefore possible to produce joining strips of a width less than that of the single joining tabs of the cone technique.
  • the two bands may also possibly cover a different width.
  • the invention therefore provides a new process assembly and new packaging which have appreciable advantages over the prior art.
  • Figures 1 and 2 are cross sections of the edges of two end panels of a blank of corrugated cardboard, respectively before and after bonding on the adjoining panel in order to produce a face of a package;
  • Figure 3 is a perspective view of a package according to the invention, in which the free edges of the panels assembled recto-verso are, after assembly, arranged in the central part of a face of the package.
  • the double-sided corrugated cardboard blank with a fluted layer used to produce the packaging shown, comprises parts of rectangular panels such as 1 and 4, the panels being attached two to two by a fold line.
  • the panels 1 and 4 of the blank have a free edge parallel or perpendicular to the corrugated cardboard grooves, and it is these panels which it is desired to assemble to form one face of a package.
  • Such packaging (an American box) is shown in Figure 3. It includes a longitudinal wall formed of a single: rectangular panel 23, two transverse walls 22 and 24, adjoining by a fold line to the panel 23 and provided with flaps 22 and 24 'respectively, and a second longitudinal wall resulting from the two-sided assembly, using cover strips 25 and 26, in accordance with the invention, of a panel 21, adjoining the wall 22 by a fold line, and a panel 21a adjoining the wall 24.
  • cover strips 25 and 26 also bring together in this case the flaps 21, and 21'a adjoining their upper part and the lower part of panels 11 and 11 a.
