Description

The present invention relates generally to packaging

  made of cardboard, corrugated board or other suitably cut sheet material and

  groove, for example from a single blank.

  It relates more particularly to those packages which comprise, in a generally prismatic volume, a peripheral side wall and two end transverse walls, one forming a bottom, the other forming a cover, and said peripheral side wall is formed of 'a plurality of side panels

  connected in pairs by fold lines forming ridges.

  Most often, to date, the volume of these packages is strictly prismatic, the edges of their peripheral lateral wall extending rectilinearly over their entire height, perpendicular to their transverse end walls, and the constituent side panels. of this peripheral lateral wall being all perfectly flat over their entire surface. Most often, too, the cross section of these packages is, for the sake of simplicity, strictly quadrangular, that is to say

square or rectangular.

  But, alternatively, it can also be

  polygonal, and for example hexagonal.

  In any case, and regardless of the decor that they can wear, these packages do not have to

  this day that a strict conditioning function.

  The present invention generally relates to a provision of such a nature as to enable them, by

  technical characteristics, to have also through them-

  even an additional function of attraction.

  More specifically, it firstly relates to a packaging made of cardboard, corrugated cardboard or other suitably cut and grooved sheet material, of the kind comprising, in a generally prismatic volume, on the one hand, a side wall formed of a plurality of side panels connected in pairs by fold lines forming ridges, and, secondly, two transverse end walls, this package being generally characterized in that, for one at least one of said side panels, hereinafter, for convenience, directional side panel, the folding lines are, over at least part of their height, zigzag fold lines whose salient and re-entrant angles, arranged respectively at the same levels, are respectively oriented in opposite directions and are connected two by two by parallel fold lines, so that on at least part of its height, said directional side panel e st is formed by a plurality of isosceles trapezoid facets alternately joined two by two by their small base and their large base; she still has for

  object a clean flan to the constitution of such a package.

  When mounting the packaging according to the invention, that is to say, its setting volume, the directional side panel with zigzag fold lines that includes

  typically takes an accordion look.

  Experience shows, indeed, that it is enough to discipline by a footprint the parasitic folding lines then developing at the border of such a

director's side panel.

  Preferably, the packaging according to the invention thus comprises, in opposite positions with respect to one another, two directional side panels with lines of

zigzag folding.

  While remaining quadrangular at its ends, its cross section is then hexagonal in its current part, following, alternatively, two different contours for this cross section, one corresponding to the large base of the isosceles trapezium facets constituting its side panels. directors,

  the other corresponding to their small base.

  In any case, deviating from a strictly prismatic volume, and thus different from conventional packaging of the same type, the packaging according to the invention advantageously has a particularly attractive character likely to attract a buyer potential of the product. the packaging of which it is used and thus to favor the purchase of this product. The characteristics and advantages of the invention

  will emerge from the description which follows,

  by way of example, with reference to the appended diagrammatic drawings in which: FIG. 1 is, with a local detachment, a plan view of a blank suitable for constituting a package according to the invention; FIGS. 2A, 2B are plan views which, similar to that of FIG. 1, illustrate two successive phases of the folding in the workshop of this blank; FIGS. 3A, 3B are perspective views illustrating two successive phases of its setting in volume at its places of use; FIGS. 4 and 5 are cross-sectional views of the packaging obtained at the end of this volume increase, respectively, respectively, the lines

IV-IV and V-V of Figure 3B.

  Intended for the constitution of a package 10 comprising, in a generally prismatic volume, FIG. 3B, on the one hand, a lateral wall 11, formed of a plurality of side panels 13, 14 (14A or 14B) connected two to one another. two by fold lines 15, 16 forming edges, and, secondly, two transverse end walls 12, 17, one forming a bottom, the other forming a cover, the blank shown in FIG. designated by the same reference as the corresponding packaging, and the same applies to the various side panels and the various fold lines concerned, shall consist, in one piece, duly aligned with each other, and duly separated two by two by the folding lines 15, 16 corresponding, the side panels 13, 14 (14A or 14B) necessary. These side panels 13, 14 (14A or 14B) all have

same height.

  In the embodiment shown, they

are six in number.

  There is thus, successively, a side panel 13, delimited by fold lines 15, two side panels 14A, 14B, separated from each other by a fold line 16, and, under the same conditions , a second side panel 13 and two other side panels 14A,

14B.

  In a manner known per se, one of the side panels of this alignment, and it is in this case a side panel 13, extends, beyond a fold line 15, by a band of solidarity 18 specific to the

  closure, on itself, in sheath, of the whole.

  In a manner also known per se, of the one and the other side of the alignment that they form, the side panels 13, 14 (14A or 14B) extend, each respectively, laterally, according to modalities described in more detail later, by flaps 20, 21 or 21 'clean together with the formation of the end transverse walls 12, 17 of the desired package 10. According to the invention, for at least one of the

  side panels 13, and in practice for each of these

  ci, the fold lines 15 are zigzag.

  For convenience, these side panels 13 are here referred to as directional side panels because, at the time of assembly, the zigzag fold lines 15 delimiting them form guidelines for the

  configuration of the corresponding packaging 10.

  Each zigzag fold line 15 comprises, alternately, a succession of reentrant angles R and salient angles S. In the embodiment shown, there is thus, in a regular pitch P, three reentrant angles R and two projecting angles S. From one zigzag fold line 15 to the other, the re-entrant angles R and the salient angles S are respectively arranged at the same levels and they are connected two by two by parallel fold lines, 22 for the reentrant angles R, and 22 'for the salient angles S. But they are respectively oriented in opposite directions. In other words, the reentrant angles R are directed toward each other, and the salient angles S are

open towards each other.

  As a result, over at least part of its height, and in practice, over the whole of it, each directional side panel 13 is formed by a plurality of isosceles trapezoidal facets 23 alternately contiguous two by two. their small base

and their big base.

  In practice, the small base of these isosceles trapezoid facets 23 is materialized by a fold line 22 connecting two reentrant angles R, and it is a fold line to which corresponds the same direction of folding as that to which correspond the lines of

zigzag folding 15.

  Together, their large base is materialized by a fold line 22 'connecting two projecting angles S, and it is a fold line which corresponds to a direction of folding opposite to that to which they correspond.

zigzag fold lines 15.

  In the embodiment shown, the directional side panels 13 each comprise six isosceles trapezoidal facets 23, all of the same height P,

  and they are identical to each other.

  The side panels 14A, 14B present between these directional side panels 13, on either side thereof, and hereinafter referred to simply by convenience as intermediate side panels, extend symmetrically with respect to each other. the other side of the fold line

16 corresponding.

  They thus extend each between, on the one hand, this fold line 16, which is common to them, and a

zigzag fold line 15.

  In practice, the fold line 16 is a line

  straight bending along its entire length.

  In practice, also, the intermediate side panels 14A, 14B are each formed by a

  plurality of triangular facets.

  In the embodiment shown, these

  Triangular facets are of three types.

  First of all, joined by one side to the zigzag fold line 15, with the opposite vertex on this side on the right fold line 16, triangular facets 24 symmetrical two by two with respect to bending 25 'which, each disposed respectively in the extension of the fold lines 22, each correspond to a direction of folding opposite to that to which these fold lines 22 correspond, and therefore inverse to that to which correspond the zigzag fold lines 15. In practice, in the embodiment shown, there are thus three pairs of triangular facets 24 on the height of each of the panels of

intermediate side 14A, 14B.

  Then there are, between these triangular facets 24, triangular facets 26, which are joined at one side to the right fold line 16, and whose opposite to this side is on the zigzag fold line 15

  corresponding to one of the salient angles S thereof.

  In the embodiment shown, these

  triangular facets 26 are two in number.

  They have a substantially equilateral outline, and normally they are devoid of any fold line. Finally, at the ends of the intermediate side panels 14A, 14B, right triangular facets 27 contiguous to the right fold line 16 by one of the sides

from their right angle.

  Overall, the triangular facets 24, taken in pairs, the triangular facets 26 and the triangular facets 27 are delimited between them by fold lines 28, which cross-cut on the right fold line 16 and which correspond to a direction of rotation. reverse folding of the one to which the lines of

zigzag folding 15.

  In practice, in the embodiment shown, the intermediate side panels 14A, 14B thus formed have, on each side, in common, the same flap 21 or 21 ', and the right fold line 16 which

  separates also affects this flap 21 or 21 '.

  On one side, it is a flap 21, whose surface corresponds to that of the transverse walls 12, 17

  to form, and which is extended by a tongue 29.

  On the other side, it is a flap 21 ', of smaller section, assigned, at its root, a bow cut 30 proper to the insertion of the tongue 29 previous. From one pair of intermediate side panels 14A, 14B to the other, the corresponding arrangements are upside down. In other words, for one of these pairs, the flap 21 is on one side while for the other it is on the other side.

  opposite side, and it is the same for the flap 21 '.

  For example, and as shown schematically with the aid of a local cutaway in FIG. 1, the blank 10 as well

  formed can be made of double-sided corrugated cardboard.

  But it can also be made of any other sheet material suitably

cut and grooved.

  In the figures, and conventionally, the cutting lines have been represented in continuous lines and the fold lines corresponding to the creasing practiced in dashed lines, whether it be dashes for the zigzag fold lines 15, or whether it is mixed lines for the straight fold lines 16, or that it is dashed for the fold lines 22, 22 ', 25' and 28 intended, they, to simply discipline

the corresponding folding.

  For the folding, in the workshop, of the blank 10, it is

for example, method as follows.

  In a first step, FIG. 2A, it is proceeded to draw over, on the rest of the blank 10, that of the directional side panels 13 which is extended by a securing strip 18 and the intermediate side panel 14A which is immediately adjacent to it. by folding 180 around the corresponding right fold line 16. In a second step, FIG. 2B, and after gluing the fastening strip 18, as schematized by hatching in FIG. 2A, the extreme intermediate side panel 14B is folded against this fastening strip 18, by folding

  180 around the corresponding right fold line 16.

  Its ends being thus mutually secured to one another by gluing, the blank 10 is then closed on itself in tubular sleeve available flat, and it is directly adapted to the constitution of the package 10

research.

  To put it in volume, it suffices, according to the arrows F of FIG. 2B, to exert opposite thrusts

  on the straight fold lines 16 forming its edges.

  As can be seen in FIG. 3A for one of them, the directional side panels 13, which are in opposite positions with respect to each other, then unfold.

each accordion.

  It is then proceeded to fold the flaps 20, 21 and 21 'at 90, with engagement of the tongue 29 of the

  flap 21 in the cutout 30 of the flap 21 '.

  The transverse end wall 12 thus formed is flat and quadrangular, with the contour of the

flap 21.

  As a result, the triangular end facets 27 of the intermediate side panels 14A, 14B, initially dihedral with respect to each other, align with each other to form coplanarly at the corresponding end of these intermediate side panels 14A, 14B, a cutaway 31 through which these intermediate side panels 14A, 14B connect

to one another.

  After filling the packaging 10 thus constituted, it is likewise done at the upper end of this package 10, for the constitution of its wall

transverse end 17.

  As will be noted, this package 10 comprises, at the corners of its transverse end walls 12, 17, four zigzag edges, each formed respectively by

the zigzag fold lines 15.

  In the median zone of two opposite sides of these transverse end walls 12, 17, it further comprises two ridges formed by the straight fold lines 16. But these straight fold lines 16 themselves form a straight edge only. on the middle part of the height of intermediate side panels 14A, 14B

correspondents.

  Indeed, because of the formation of the cut sections 31, as explained above, their ends are inflected towards the transverse end walls 12, 17. As will be noted, also, while these transverse walls of end 12, 17 have a quadrangular contour, the peripheral side wall 11 of the package 10 according to the invention has, in its part

  current, a generally hexagonal section.

  But, in practice, this hexagonal section is,

  alternately, of two different types.

  First, there is, in FIG. 4, a hexagonal section of which two opposite sides are formed by

fold lines 22 '.

  There is, then, figure 5, a hexagonal section whose two opposite sides corresponding to the previous ones

  are formed by fold lines 22.

  The package 10 according to the invention may be suitable

  the packaging of any product.

  But it is particularly suitable for

  individual packaging of a bottle.

  Of course, the present invention is not limited to the embodiment described and shown, but

  encompasses any variant of execution.

  In particular, the number of constituent facets of its directional side panels is

indifferent.

  Nor is it necessary that these facets are all identical to each other, such or such of their dimensions, and for example their height, which can be

  otherwise vary from one to the other.
