Definitions

  • the present invention refers to a method for manufacturing cardboard boxes, and to a box obtained with this method.
  • a method for manufacturing cardboard boxes which is described in Spanish Patent application no. 9300188 (PAPER, S.A.), publication number ES 2067382, starts from separate sheets, with lugs on the sides and flaps at the ends facing each other two by two. These sheets are applied onto the external faces of a mandrel, along which the various steps of the method are carried out to provide a rectangular prismatic body whose bases are provided with open flaps and whose edges are reinforced by folded lugs glued to the sides of the body, beside the edges.
  • the method object of the aforesaid patent provides other advantages which are, in summary: the possibility of some sides of the box being of different quality and thickness than the others, or presenting fibres running in different directions in order to withstand stresses in any direction.
  • the method of the invention is characterized in that the lugs which project from the sides of the sheets are applied and joined together over chamfered edges provided on the mandrel. These chamfered edges are situated between two adjacent sides of the mandrel.
  • At least one of the pairs of sheets from which the box is obtained presents prolongations from the respective lugs. These prolongations are applied and joined to an adjacent zone of the sheet, immediately beside the chamfered edges upon which the lugs in question are applied.
  • all the sheets from which the box is obtained present prolongations from their respective lugs. These prolongations are applied and joined to a zone of the sheet immediately adjacent to the chamfered edges upon which the lugs in question are applied.
  • the box obtained with the method described is provided with chamfered edges (or chamfers) between its sides and on which are superimposed and glued the folded lugs of the adjacent sheets, forming two cant edges between each pair of sheets.
  • At least one of the superimposed lugs forming the chamfered edges of the box presents a prolongation folded and glued onto the adjacent side, beside the chamfered edges.
  • each of the superimposed lugs which form the chamfered edges of the box present corresponding prolongations folded and glued onto the adjacent side, beside the chamfered edges.
  • Figure 1 is a schematic cross-section showing the moulding core and a pair of sheets with their lugs prior to application against the chamfered edges of the moulding core;
  • Figure 2 is a similar view showing another pair of sheets with their lugs extended, on the point of being applied and glued to the lugs of the first two sheets;
  • Figure 3 is a view similar to the previous two, showing the lugs which form each chamfered edge glued together;
  • Figure 4 is a view similar to that of Figure 3, but in this example two of the sheets have their corresponding prolongations folded and glued to the adjacent sheets;
  • Figure 5 is a view very similar to that of Figure 4, but in this case it is the other two sheets which present the corresponding prolongations to their lugs;
  • Figure is a view similar to those of Figures 4 and 5, showing a version in which all the sheets present lugs with prolongations folded and glued to the adjacent sides;
  • Figure 7 is a perspective view showing one of the chamfered edges of the box obtained according to the
  • the method for manufacturing of boxes consists, according to the representation shown in the drawings, in applying successively two pairs of sheets -1- and -2- against the sides of a moulding core -3- provided with chamfered edges -4- situated between sides -5- of the moulding core.
  • the sheets -1- have some lugs -6- on both sides, while the sheets -2- have similar lugs -7-.
  • the lugs -6- and -7- have prolongations -6a- and -7a-, respectively.
  • the sides -9- will also be reinforced by said prolongations glued beside the chamfered edges -8-.
