Definitions

  • the present invention relates to boxes of cardboard, corrugated cardboard or similar sheet material, as well as the blanks of such material for the production of said boxes and a machine for producing said boxes from said blanks.
  • the section of the load constituted by said objects or groups of objects is constant over the entire height of said load and adapts best, along the height of the body in which said load is introduced, in the form of said box, so that at least some projecting corners of said box are empty.
  • these empty protruding corners of the box which are exposed to external aggressions, can be easily torn, which is detrimental to the presentation and protection of the packaged products.
  • the empty corners of the box are a waste of sheet material, since they are unnecessary.
  • the object of the present invention is to remedy these drawbacks.
  • a blank is proposed according to claim 1. It is also proposed a box obtained with such a blank, according to claim 4.
  • US-A-2,643,815 relates to a box, intended to contain bulk products, comprising trapezoidal flaps connected to each other by triangular gussets intended to form the seal between the trapezoidal flaps when the the bulk product is poured out of the box using the spout formed by the pyramidal part of the box.
  • the gussets forming an integral part of the flaps, require, during the formation in the box, a specific folding, incompatible with the techniques of industrial production of the boxes.
  • the box according to the invention comprises lateral tabs ensuring sealing along the lateral edges of said pyramid.
  • Said other lateral faces could be triangular.
  • they are given a trapezoidal shape.
  • At least some of said second flaps have, along at least one of their inclined edges, a folding triangular tab, connected to said corresponding second flap by a fold line.
  • the blank comprises a second set of lateral flaps arranged on the side of the small base of said second flaps, connected to these by fourth fold lines perpendicular to said first fold lines and intended to form at least partially a sealing face for said box.
  • a first flap and a second flap of said blank are perfectly positioned relative to the mandrel and held relative to the corresponding faces of the latter during the winding of said blank, so that the box obtained is particularly precise in shape.
  • said means for fixing to each other said second flaps comprise means for folding down said triangular tabs and for fixing them to the second flaps which are adjacent to those which carry them.
  • said means for winding said series of first flaps around the mandrel comprise a movable assembly comprising tilting arms.
  • Figure 1 shows, flat, a blank of sheet material for the manufacture of an exemplary embodiment of a box according to the present invention.

  • the triangular tabs 16 of the flap 12.2 are housed respectively between the latter and the flaps 12.1 and 12.3, while a triangular tongue 16 of the shutter 12.4 and housed between the latter and the shutter 12.3.
  • the other triangular tongue 16 of the flap 12.4 projects outwards, on the side of the tongue 8.
  • the blank F is intended to form, by winding and securing the flaps 1 to 4 and securing the flaps 12.1 to 12.4 and the flaps 10.1, 10.2, 10.3, 10.4,14.1, 14.2, 14.3 and 14.4 as described below more in detail with reference to Figures 6 to 16 - the body C shown in Figure 3.
  • the body C has the general appearance of a parallelepiped pa surmounted by a pyramid py .
  • the large lateral faces of the parallelepiped pa are formed by flaps 1 and 3 while the small lateral faces of the latter are formed by flaps 2 and 4, the flaps 12.1, 12.3 and 12.2, 12.4 respectively forming the large faces and the small faces of the pyramid py .

  • the flaps 10.2 and 10.4 are identical to each other. They have a length equal to the length 1 of the flaps 2 and 4.
  • FIG 2 there is shown the box C with its open pyramid, so as to show the relative arrangements of flaps 12.1 to 12.4, flaps 14.1 to 14.4 and the tabs 16.
  • the provision of Figure 2 does not occur during the manufacturing process described below, the box being automatically closed on the side of its pyramid.
  • FIG. 4 there is illustrated, in vertical section, an application of the box C to the packaging of bottles B separated by a separation spider S. It can be seen that, thanks to the pyramidal part py of the box c, corresponding to the flaps 12.1 to 12.4, the upper part of the bottles B is joined by the box C.
  • the empty projecting corners 18 (dotted lines) are eliminated and replaced by inclined walls which are not very vulnerable to external aggressions.
  • at each corner compared to a known rectangular box, it can be seen that less sheet material is used, the saving for each upper corner being able to amount to approximately 30%.
  • FIGS. 8 to 16 a machine is schematically illustrated allowing the manufacture of the body C, with the pyramidal part py closed by the flaps 14.1 to 14.4, but the bottom (formed by the flaps 10.1 to 10.4) open.
  • FIGS. 8 to 16 a machine is schematically illustrated allowing the manufacture of the body C, with the pyramidal part py closed by the flaps 14.1 to 14.4, but the bottom (formed by the flaps 10.1 to 10.4) open.
  • the machine of FIGS. 8 to 16 comprises a mandrel 20 (shown on a larger scale in FIG. 5), the external shape of which corresponds to the internal shape of the box C to be obtained from the blank F.
  • the mandrel 20 comprises a parallelepiped part 21 extended by a pyramidal part 22.
  • the length of the parallelepiped part 21 of the mandrel 20 may be different from the height h of the side panels of the body C.
  • the mandrel 20 may be solid or only made up of a frame delimiting its edges, as shown in said Figures 6 and 7. In these figures, it has been assumed that said mandrel 20 consisted of profiles 23 (seen in section in FIGS.
  • FIGS. 7a to 7c defining rectangular lateral support faces 24 to 27 for the flaps 1 to 4 of the blank F, folding edges 28 to 31 corresponding to the folding lines 5 to 9, trapezoidal bearing faces 32 to 35 for the flaps 12.1 to 12.4, junction edges 36 to 39 for the latter and a front bearing face 40 for the flaps 14.1 to 14.4, the contour of said front bearing face 40 forming fold edges corresponding to the fold lines 15.1 to 15.4 of said flaps 14.1 to 14.4.
  • FIGS. 6a, 6b, 6c and 7a, 7b, 7c the process of positioning the blank F relative to the mandrel 20 is illustrated diagrammatically, when it is desired to apply the intermediate flap 3 against the corresponding lower face 24 of the mandrel 20.
  • flap 3 is brought closer to the bearing face 24 by means of a pressure plate 50 (see Figure 5), whose profile is concave and which, longitudinally relative to the mandrel 20, has a face 51 superimposed on the rectangular face 24 of said mandrel and a face 52 superimposed on the trapezoidal face 32 of the mandrel 20, the faces 51 and 52 being connected to each other by an edge 53 superimposed on the edge 41 connecting said faces 24 and 32 of said mandrel 20.
  • a pressure plate 50 see Figure 5
  • the flaps 2.1 on the one hand, and the flap 4 and the tongue 8 on the other hand are in abutment against the mandrel 20 (see FIG. 6b), which generates a lateral guiding effect and positions the side exactly flap 3 relative to the bearing face 24 (see FIG. 6c).
  • the trapezoidal faces 32 and 52 exert pressure on the flap 12.3, by folding it around the fold line 13.3 connecting it to the flap 3 and sliding the blank F longitudinally so that this fold line comes to the plumb with edge 41 (see FIG. 7b).
  • the plate 50 presses the shutter 3 between the bearing face 24 see FIGS. 6c and 7c
