Definitions

  • the present invention relates to a blank for making a rectangular container open at its upper end such as a fruit and vegetable tray and which is of the type consisting of a blank of cardboard cut and grooved and comprising the vertical edges of the container interior vertical reinforcements.
  • the cut and creased cardboard blank forms the bottom and two vertical walls of the container to be formed.
  • the reinforcements are connected in pairs with each other to form the other two opposite vertical walls of the container. They are most often connected together by strips of unrolled wood to increase the rigidity of the container obtained.
  • Such a structure is complex because the container must be assembled from three separate parts and this assembly is long and expensive and is difficult to mechanize on machines working at high speeds.
  • the object of the present invention is to design a cutout of said type, the assembly of which is easy and rapid and can be implemented using automatic devices working at high rates.
  • said cardboard blank is in the form of a single piece comprising all the parts intended to form the bottom and the vertical walls as well as the sealing tabs of the container, said reinforcements being fixed to said blank when the latter ci extends flat in a horizontal plane before the forming of the container to be formed.
  • a cut is thus obtained consisting of a single piece and the reinforcements are fixed flat on the cardboard blank.
  • This cutout can be handled and transported flat and be shaped only at the time of use by simple folding and sealing.
  • the part of the cardboard blank comprises, opposite the neighboring ends of the reinforcements, perforated parts whose section corresponds substantially to that of the reinforcements, the latter extending beyond the outer or upper edges of the parts of the blank intended to form the vertical walls of the container.
  • the present invention also relates to a method for assembling the blanks according to the invention.
  • the method according to the present invention consists in depositing the reinforcements in predetermined positions on a horizontal conveyor in motion, depositing on the upper face of each reinforcement a layer of adhesive material, depositing on all of the adhesive reinforcements said cut and grooved cutout and lifting the part intended to form the bottom of the container to be formed in a vertical direction so that the parts of the cutout carrying the reinforcements are folded down under the action of gravity, folding the other two parts of the cutout and sealing the tabs on the first said parts by keeping the parts in a vertical position perpendicular to the plane of the part forming the bottom of the container.
  • the assembly can thus be carried out continuously without complex manipulations of the cardboard blank and the reinforcements.
  • shaping the cutout to form the container is a simple and rapid operation.
  • the blank according to the invention represented in FIG. 1 consists of a board blank, for example of corrugated board, bearing the general reference (1) and which is produced in one piece by cutting from a plane of rectangular cardboard.
  • the cutout (1) comprises a central part (2) intended to form the bottom of the container to be formed, two parts (3) forming the longitudinal vertical walls and two parts (4) forming the transverse vertical walls of the container to be formed.
  • Each part (3) further comprises two sealing tabs (5) allowing the parts (3) to be linked to the parts (4) after the container has been shaped when the parts (3) and (4) extend perpendicular to the bottom (2).
  • the two parts (4) intended to form the transverse vertical walls of the container carry, in the vicinity of their lateral ends, reinforcing uprights (6) made of wooden elements of triangular section. These reinforcements or uprights (6) extend beyond the outer or upper end of the corresponding part (4) laying and are fixed on it by gluing before the shaping of the cut when the different parts (2, 3 and 4) of the cut (1) lie flat in the same plane.
  • the bottom part (2) of the cutout has an openwork part (7) whose section corresponds substantially to that of the reinforcements (6) and which makes it possible to in a known manner a vertical stacking of several containers made from blanks according to the present invention.
  • folding starters (8) produced, for example, by grooving and which allow the folding of the parts together compared to the others for the shaping of the cutout.
  • Figures 2 to 5 show the essential phases of the method according to the invention for shaping the cutout shown in Figure 1.
  • a conveyor belt (9) horizontal carrying tabs (10) for positioning and driving the reinforcements (6) of the predetermined relative positions corresponding to their position on the blank of cardboard cut and grooved (1).
  • a glue distributor gun (11) for positioning and driving the reinforcements (6) of the predetermined relative positions corresponding to their position on the blank of cardboard cut and grooved (1).
  • a glue distributor gun 11
  • a layer of an adhesive material (12) is deposited on the upper face of each reinforcement (6 ), Figure 2.
  • the cut and grooved blank (1) is deposited on the reinforcements (6) to seal it on these thanks to the layer of adhesive.
  • This operation can easily be carried out without stopping the conveyor using a cut-out dispenser of a known type placed above the conveyor.
  • the bonding of the blank can be replaced by fixing the blank by stapling known per se.
