Definitions
- the present invention relates to a method of reinforcement of the stacking resistance of the walls carrying a corrugated packaging and a conditioning obtained by this process.
- the flutes of the corrugated cardboard must be oriented vertically in the walls side and in the flaps and therefore the double discharge lines must be oriented in a direction perpendicular to the cardboard grooves.
- These double delivery lines are made by marking on the cardboard blank from which the packaging comes, two very close parallel fold lines. In the packaging in the assembled state, the narrow strip defined between the two fold lines is in principle straight and contained in a horizontal plane.
- this strip has an irregular profile, due to the fact that poorly controlled crushing of corrugated cardboard flutes on the discharge lines.
- this band is often curled or has a certain degree of warping. It follows that when several packaging is stacked, the compression force may to exercise only on certain discrete points of the edge upper side walls. At these points, the side walls may buckle or show some fatigue which reduces its resistance to stacking.
- the flap has a height exactly equal to that of the side wall, so that its bottom edge reaches the same level as the underside of the bottom wall. he as a result that when several packages are stacked, the side wall and the flap of each are supported on the side wall and the flap of the underlying packaging.
- the compression force is therefore equally distributed between the side wall and the flap and is exerted uniformly on the entire length of these.
- the invention also relates to a packaging obtained by the method described above.
- the blank portion 20 comprises a bottom wall 22 on which a flap 24 is articulated by a fold line 26.
- the fold line is formed on the face of the blank intended to be inside the packaging, and which is the visible side in FIG. 1.
- the shutter has a width L which is twice the height h of the box that we want to make.
- a half-cut 28 is made which cuts the cardboard over its entire thickness with the exception of the outer cover sheet 18.
- the section 28 defines on the shutter a side wall 30 articulated to the bottom wall 22 by the fold line 26 and a flap 32 which is attached to the side wall only by the line 34 not cut from the outer cover sheet 18.
- the fold line 26 and the cut 28 are perpendicular to the direction of the grooves 35.
- Figure 3 shows how the blank is folded: the flap 24 to bring it into position perpendicular to the bottom wall 22, by folding around the fold line 26, then fold the flap 32 outward around the connecting line 34. The flap is then glued to the face exterior of the side wall.
- the section 28 is straight, we obtain at the upper part of the side wall and the flap a very regular, flat and horizontal cutting surface 36 on its entire length.
- the lower edge 27 of the flap is is at exactly the same level as that of the face lower 40 of the bottom wall. It results from these two characteristics only if several packages are stacked, the compressive force is distributed equally over the side wall and the flap of each package and evenly along the length of these elements. The packaging therefore has good compressive strength higher than that of wrapped packaging internally.
- FIG. 4 shows the blank 50 from which is made the set.
- This blank is substantially rectangular and comprises a central bottom wall 52 of square shape or rectangular, two longitudinal walls 54, 56 articulated by fold lines 58, 60 along two sides parallels of the bottom wall and two flaps 62, 64 articulated by fold lines 66, 68 along the two other sides of the bottom wall.
- the flaps 62, 64 have a width greater than or equal to twice that of the walls longitudinal 54, 56.
- rectilinear slots 70, 72 and 74, 76 are formed from the two longitudinal edges of the blank, in alignment with the fold lines 66, 68 and over a distance d substantially equal to twice the width l of the longitudinal walls.
- the flaps 62, 64 are shared by half-cut sections 78, 80, in strips 82, 84 and 86, 88 of equal width l .
- the strips 82, 84 are separated at their ends by incisions 90, 92, the same length as the slots 70, 72.
- the inner legs 94, 98, i.e. those associated with the band interior 82, can be folded along lines of folding 102, 104 passing through the ends of the slots 70, 72.

- U-shaped incisions are made on the band outer 84, from the half-cut section 78, from so as to release centering pins 126, 128.
- recesses 130, 132 of shape complementary to that of pins are drilled in the inner band 82, along the transverse fold line 66. These recesses are intended to receive the pins of a packaging inferior.
- the packaging tray is shaped as follows: we start by erecting the flaps 62, 64 perpendicular to the bottom wall 52 by folding around fold lines 66, 68, then fold the strips 84, 88 outwards, by folding around the half-cuts 78, 80 to apply against the face exterior of interior strips 82, 86. The strips outside are glued on the inside strips.
- This tray is particularly resistant because it has two transverse load-bearing walls each formed of two cardboard thicknesses and also because the ends longitudinal walls are sandwiched between the interior tabs and exterior tabs.

Abstract
Description
La présente invention concerne un procédé de renforcement de la résistance au gerbage des parois porteuses d'un conditionnement en carton ondulé et un conditionnement obtenu par ce procédé.The present invention relates to a method of reinforcement of the stacking resistance of the walls carrying a corrugated packaging and a conditioning obtained by this process.
Il est connu de renforcer la résistance au gerbage des parois porteuses d'un conditionnement en carton ondulé en repliant ou en rembordant vers l'intérieur du conditionnement des rabats qui sont articulés sur le bord supérieur des parois porteuses par des doubles lignes de refoulement. Ces rabats qui ont une largeur sensiblement égale à la hauteur des parois, viennent s'appliquer sur la paroi intérieure de ces dernières et leur bord libre inférieur se cale contre la paroi de fond du conditionnement. L'épaisseur des parois se trouve ainsi doublée sur toute la hauteur.It is known to strengthen the stacking resistance of load-bearing walls of a corrugated cardboard packaging in folding or folding inward packaging of the flaps which are hinged on the edge upper load-bearing walls by double lines of repression. These flaps which have a width substantially equal to the height of the walls, are applied on the inner wall of the latter and their free edge lower wedges against the bottom wall of the conditioning. The thickness of the walls is thus doubled over the entire height.
Pour donner le maximum de résistance à la compression aux parois transversales, les cannelures du carton ondulé doivent être orientées dans le sens vertical dans les parois latérales et dans les rabats et par conséquent les doubles lignes de refoulement doivent être orientées dans une direction perpendiculaire aux cannelures du carton. Ces doubles lignes de refoulement sont réalisées en marquant sur le flan de carton dont est issu le conditionnement, deux lignes de pliage parallèles très rapprochées. Dans le conditionnement à l'état monté, l'étroite bande définie entre les deux lignes de pliage est en principe rectiligne et contenue dans un plan horizontal.To give maximum resistance to compression at the transverse walls, the flutes of the corrugated cardboard must be oriented vertically in the walls side and in the flaps and therefore the double discharge lines must be oriented in a direction perpendicular to the cardboard grooves. These double delivery lines are made by marking on the cardboard blank from which the packaging comes, two very close parallel fold lines. In the packaging in the assembled state, the narrow strip defined between the two fold lines is in principle straight and contained in a horizontal plane.
Toutefois, l'expérience montre que, la plupart du temps, cette bande a un profil irrégulier, dû au fait que l'on maítrise mal l'écrasement des cannelures du carton ondulé sur les lignes de refoulement. On constate que cette bande est souvent gondolée ou qu'elle présente un certain degré de gauchissement. Il en résulte que lorsque plusieurs conditionnements sont gerbés, la force de compression risque de ne s'exercer que sur certains points discrets du bord supérieur des parois latérales. Au niveau de ces points, les parois latérales peuvent flamber ou présenter une certaine fatigue qui diminue sa résistance au gerbage.However, experience shows that, most of the time, this strip has an irregular profile, due to the fact that poorly controlled crushing of corrugated cardboard flutes on the discharge lines. We see that this band is often curled or has a certain degree of warping. It follows that when several packaging is stacked, the compression force may to exercise only on certain discrete points of the edge upper side walls. At these points, the side walls may buckle or show some fatigue which reduces its resistance to stacking.
Un autre inconvénient du rembordement des parois latérales vers l'intérieur réside dans le fait que le contact entre le bord inférieur des rabats et la paroi du fond est relativement élastique en raison de la présence dans la paroi du fond des cannelures du carton. Ainsi, lors du gerbage, les parois latérales peuvent subir une légère déformation due à l'écrasement des cannelures de la paroi du fond.Another disadvantage of the overhang of the walls sideways inwards lies in the fact that the contact between the lower edge of the flaps and the wall of the bottom is relatively elastic due to the presence in the back wall of the cardboard grooves. So when stacking, the side walls may undergo a slight deformation due to crushing of the grooves in the wall of the background.
La présente invention vise à remédier à ces
inconvénients et propose en premier lieu un procédé de
renforcement des parois porteuses d'un conditionnement
réalisé à partir d'un flan en carton ondulé à au moins une
couche cannelée, dans lequel chacune des parois porteuses
est constituée par un volet articulé sur la paroi de fond du
conditionnement par une ligne de pliage, ledit procédé étant
caractérisé en ce qu'il consiste :
On obtient ainsi au sommet de la paroi latérale et du rabat contigu une surface d'appui parfaitement plate et horizontale, de largeur égale au double de l'épaisseur du carton. Cette surface offre un appui stable et régulier pour un autre conditionnement.This gives the top of the side wall and flap adjoining a perfectly flat support surface and horizontal, of width equal to twice the thickness of the cardboard. This surface provides stable and regular support for another conditioning.
Le rabat a une hauteur exactement égale à celle de la paroi latérale, de sorte que son bord inférieur arrive au même niveau que la face inférieure de la paroi de fond. Il en résulte que lorsque plusieurs conditionnements sont gerbés, la paroi latérale et le volet de chacun d'eux s'appuient sur la paroi latérale et le volet du conditionnement sous-jacent.The flap has a height exactly equal to that of the side wall, so that its bottom edge reaches the same level as the underside of the bottom wall. he as a result that when several packages are stacked, the side wall and the flap of each are supported on the side wall and the flap of the underlying packaging.
L'effort de compression est donc également réparti entre la paroi latérale et le rabat et s'exerce uniformément sur toute la longueur de ces derniers.The compression force is therefore equally distributed between the side wall and the flap and is exerted uniformly on the entire length of these.
L'invention concerne également un conditionnement obtenu par le procédé décrit ci-dessus.The invention also relates to a packaging obtained by the method described above.
Un mode de réalisation de l'invention sera décrit à
présent en regard du dessin annexé dans lequel :
On expliquera tout d'abord le principe du procédé de
renforcement selon l'invention en se reportant aux figures 1
à 3 qui représentent une portion de flan en carton ondulé
comprenant deux couches cannelées 10, 12 séparées par une
feuille de papier intermédiaire 14 et recouvertes
extérieurement par deux feuilles de couverture intérieure 16
et extérieure 18, mais comme on le verra, l'invention
s'applique également à un carton ondulé comprenant une, deux
ou davantage de couches cannelées.We will first explain the principle of the
reinforcement according to the invention with reference to Figures 1
to 3 which represent a portion of blank in corrugated cardboard
comprising two
La portion de flan 20 comprend une paroi de fond 22 sur
laquelle un volet 24 est articulé par une ligne de pliage
26. La ligne de pliage est pratiquée sur la face du flan
destinée à se trouver à l'intérieur de l'emballage, et qui
est la face visible sur la figure 1. Le volet a une largeur
L qui est double de la hauteur h de la caisse que l'on veut
réaliser. A peu près à mi-distance entre la ligne de pliage
26 et le bord 27 du volet 24, est pratiquée une coupe à mi-chair
28 qui tranche le carton sur toute son épaisseur à
l'exception de la feuille de couverture extérieure 18. La
coupe 28 définit sur le volet une paroi latérale 30
articulée à la paroi de fond 22 par la ligne de pliage 26 et
un rabat 32 qui n'est rattaché à la paroi latérale que par
la ligne 34 non tranchée de la feuille de couverture
extérieure 18.The
La ligne de pliage 26 et la coupe 28 sont
perpendiculaires à la direction des cannelures 35.The
La figure 3 montre le mode de pliage du flan : on dresse
le volet 24 pour l'amener en position perpendiculaire à la
paroi de fond 22, par pliage autour de la ligne de pliage
26, puis on plie le rabat 32 vers l'extérieur autour de la
ligne de liaison 34. Le rabat est ensuite collé sur la face
extérieure de la paroi latérale.Figure 3 shows how the blank is folded:
the
Du fait que la coupe 28 est rectiligne, on obtient à la
partie supérieure de la paroi latérale et du rabat une
surface de coupe 36 très régulière, plate et horizontale sur
toute sa longueur. De plus, le bord inférieur 27 du rabat se
trouve exactement au même niveau que celui de la face
inférieure 40 de la paroi de fond. Il résulte de ces deux
caractéristiques que si plusieurs conditionnements sont
gerbés, l'effort de compression est réparti à égalité sur la
paroi latérale et le rabat de chaque conditionnement et
uniformément sur toute la longueur de ces éléments. Le
conditionnement a donc une résistance à la compression bien
supérieure à celle des conditionnements rembordés
intérieurement.Because the
On décrira à présent en détail en regard des figures 4 et 5, un exemple de conditionnement, ici un plateau pour fromage de Brie.We will now describe in detail with reference to Figures 4 and 5, an example of packaging, here a tray for Brie cheese.
La figure 4 montre le flan 50 à partir duquel est
réalisé le plateau. Ce flan est sensiblement rectangulaire
et comprend une paroi de fond centrale 52 de forme carrée ou
rectangulaire, deux parois longitudinales 54, 56 articulées
par des lignes de pliage 58, 60 le long de deux côtés
parallèles de la paroi de fond et deux volets 62, 64
articulés par des lignes de pliage 66, 68 le long des deux
autres côtés de la paroi de fond. Les volets 62, 64 ont une
largeur supérieure ou égale au double de celle des parois
longitudinales 54, 56.Figure 4 shows the blank 50 from which is
made the set. This blank is substantially rectangular
and comprises a
Quatre fentes rectilignes 70, 72 et 74, 76 sont
pratiquées depuis les deux bords longitudinaux du flan, dans
l'alignement des lignes de pliage 66, 68 et sur une distance
d sensiblement égale au double de la largeur l des parois
longitudinales.Four
Les volets 62, 64 sont partagés par des coupes à mi-chair
78, 80, en bandes 82, 84 et 86, 88 d'égale largeur l.The
Le flan ayant une symétrie centrale, on ne décrira que la partie de gauche.The blank having a central symmetry, we will only describe the left side.
Les bandes 82, 84 sont séparées à leurs extrémités par
des incisions 90, 92, de même longueur que les fentes 70,
72. On définit ainsi aux extrémités des bandes, des pattes
indépendantes 94, 96 et 98, 100. Les pattes intérieures 94,
98, c'est-à-dire celles qui sont associées à la bande
intérieure 82, peuvent être pliées le long de lignes de
pliage 102, 104 passant par les extrémités des fentes 70,
72.The
Sur les pattes extérieures 96, 100 sont marquées des
lignes de pliage 106, 108 alignées avec les lignes de pliage
longitudinales 58, 60. Ces lignes de pliage définissent aux
extrémités des pattes, des languettes de fixation externes
110, 112.On the
Sur les pattes intérieures 94, 98 sont marquées des
lignes de pliage 114, 116 parallèles aux lignes de pliage
102, 104 et qui définissent, de part et d'autre, des
éléments de coin 118, 120 et des languettes de fixation
internes 122, 124.On the
Des incisions en forme de U sont pratiquées sur la bande
extérieure 84, à partir de la coupe à mi-chair 78, de
manière à dégager des tenons de centrage 126, 128. Des
évidements 130, 132 de forme complémentaire de celle des
tenons sont percés dans la bande intérieure 82, le long de
la ligne de pliage transversale 66. Ces évidements sont
destinés à recevoir les tenons d'un conditionnement
inférieur.U-shaped incisions are made on the band
outer 84, from the half-
La mise en forme du plateau d'emballage se fait comme
suit : on commence par dresser les volets 62, 64
perpendiculairement à la paroi de fond 52 par pliage autour
des lignes de pliage 66, 68, puis on rabat les bandes
extérieures 84, 88 vers l'extérieur, par pliage autour des
coupes à mi-chair 78, 80 pour les appliquer contre la face
extérieure des bandes intérieures 82, 86. Les bandes
extérieures sont collées sur les bandes intérieures.The packaging tray is shaped as
follows: we start by erecting the
On plie ensuite vers l'intérieur les pattes intérieures
94, 98 autour des lignes de pliage 102, 114 ; 104, 116, puis
on dresse les parois longitudinales 54, 56
perpendiculairement à la paroi de fond 52 par pliage autour
des lignes de pliage 58, 60.Then fold inward the
On colle ensuite les languettes intérieures 122, 124 sur
la face intérieure des parois longitudinales 54, 56 en
veillant à ce que les éléments de coin 118, 120 se placent
en diagonale dans les coins de la paroi de fond 52. Enfin,
on plie les languettes extérieures 110, 112 et on les colle
sur la face extérieure des parois longitudinales 54, 56.Then glue the
On obtient alors le plateau représenté à la figure 5. Ce plateau est particulièrement résistant parce qu'il possède deux parois transversales porteuses formées chacune de deux épaisseurs de carton et également parce que les extrémités des parois longitudinales sont prises en sandwich entre les languettes intérieures et les languettes extérieures.This gives the plate shown in Figure 5. This tray is particularly resistant because it has two transverse load-bearing walls each formed of two cardboard thicknesses and also because the ends longitudinal walls are sandwiched between the interior tabs and exterior tabs.
