Description

PLAQUE DE CARTON ONDULE A NOMBRE DE CANNELURES VARIABLE,
UTILISEE NOTAMMENT POUR LA CONFECTION DES CAISSES
D'EMBALLAGE, ET CAISSE D'EMBALLAGE OBTENUE.CORRUGATED CARDBOARD PLATE WITH NUMBER OF VARIABLE GROOVES,
USED IN PARTICULAR FOR THE MAKING OF CASES
PACKAGE, AND PACKING BOX OBTAINED.

La présente invention est relative à une plaque de carton ondulé à nombre de cannelures variable, servant notamment à la confection de caisses d'emballage, et aux caisses d'emballage obtenues. The present invention relates to a corrugated cardboard plate with a variable number of grooves, used in particular for making packaging boxes, and to the packaging boxes obtained.

On sait que les caisses d'emballage en carton ondulé sont construites de façon que leurs côtés verticaux résis- tent à l'empilement de ces caisses lors de leur stockage. It is known that corrugated cardboard packaging boxes are constructed so that their vertical sides resist stacking of these boxes during storage.

Aussi, ces parties de la caisse doivent-être constituées d'une épaisseur de carton suffisante, en nombre de cannelures notamment, pour résister à ladite charge verticale d'empilement des caisses.Also, these parts of the box must be made of a sufficient thickness of cardboard, in number of grooves in particular, to withstand said vertical stacking load of the boxes.

Jusqu'à présent, la plaque de carton qui servait toute entière à la confection de la caisse (par pliage et découpage) était choisie d'épaisseur homogène. Cette épaisseur correspondait à ladite valeur de résistance des côtés verticaux. Until now, the cardboard plate which was used entirely for making the case (by folding and cutting) was chosen to be of uniform thickness. This thickness corresponded to said resistance value of the vertical sides.

Cependant, les flans de fond et de couvercle de la caisse ainsi façonnée, dont l'épaisseur est identique à celle des côtés verticaux de la caisse, sont bien moins sollicités à la charge que les côtés verticaux. Il en résulte un excès d'épaisseur de matière pour ces éléments qui alourdit inutilement la caisse et grève son coût de fabrication. However, the bottom and cover blanks of the box thus formed, the thickness of which is identical to that of the vertical sides of the box, are much less stressed under load than the vertical sides. This results in an excess of material thickness for these elements which unnecessarily weighs down the body and strikes its manufacturing cost.

L'invention vise à remédier à ces inconvénients et propose une plaque de carton ondulé, notamment pour la confection de caisses d'emballage résistantes au gerbage, caractérisée en ce qu'elle comprend sur toute sa longueur une bande centrale d'épaisseur et de rigidité plus importantes, la largeur de cette dernière étant au moins égale à la hauteur des côtés verticaux de là caisse à réaliser. The invention aims to remedy these drawbacks and proposes a corrugated cardboard plate, in particular for making packaging boxes resistant to stacking, characterized in that it comprises over its entire length a central strip of thickness and rigidity larger, the width of the latter being at least equal to the height of the vertical sides of the box to be produced.

La bande centrale est avantageusement réalisée en apportant sur une plaque d'épaisseur homogène une ou plusieurs couches de papier supplémentaires selon la rigidité souhaitée pour les côtés verticaux de la caisse. The central strip is advantageously produced by providing on a plate of uniform thickness one or more additional layers of paper according to the desired stiffness for the vertical sides of the box.

Les couches supplémentaires sont avantageusement une feuille de cannelure et deux feuilles de couverture à disposer verticalement, relativement aux cotés verticaux de la caisse à réaliser, de façon à obtenir pour ces côtés une résistance verticale optimale, avec le minimum de matière. The additional layers are advantageously a flute sheet and two cover sheets to be arranged vertically, relative to the vertical sides of the box to be produced, so as to obtain for these sides an optimal vertical resistance, with the minimum of material.

La largeur de la bande centrale est de préférence légèrement plus importante que la hauteur des côtés verticaux de la caisse. De cette façon, la surépaisseur de matière débordant sur les flans de fond et de couvercle de la caisse, renforce le pli de ces derniers avec les côtés verticaux et apporte une meilleure assise de support des caisses superposées. The width of the central strip is preferably slightly greater than the height of the vertical sides of the box. In this way, the extra thickness of material overflowing on the bottom and cover blanks of the box, strengthens the fold of the latter with the vertical sides and provides better support for the stacked boxes.

L'invention a également pour objet une caisse d'empal- lage formée à partir d'une plaque de carton, telle que définie précédemment. A subject of the invention is also a packing box formed from a cardboard plate, as defined above.

L'invention est illustrée ci-après à l'aide d'un exemple de réalisation et en référence aux dessins annexés sur lesquels
- La figure 1 est une vue d'une plaque de carton selon l'invention
- La figure 2 est une vue aggrandie montrant une partie de cette plaque et
- La figure 3 est une vue d'une caisse d'emballage réalisée à partir d'une plaque de carton selon l'invention.The invention is illustrated below using an embodiment and with reference to the accompanying drawings in which
- Figure 1 is a view of a cardboard plate according to the invention
- Figure 2 is an enlarged view showing part of this plate and
- Figure 3 is a view of a packaging case made from a cardboard plate according to the invention.

Avec référence aux figures, une plaque de carton 1 selon l'invention est rectangulaire et comporte une bande centrale 3 s'étendant sur sa longueur. La bande centrale 3 est constituée d'un carton à trois cannelures 5 et 5' (figure 2) interposées entre deux feuilles intermédiaires internes 7 et 7' et recouvertes de deux feuilles externes 9 et 9'. Le reste de la plaque 11 est formé d'un carton à deux cannelures 5 (les mêmes que celles de la bande centrale) comportant une seule feuille intermédiaire interne 7 et une ou deux feuilles de couverture 9 (une seule est représentée sur le dessous). Relativement à cette partie 11, la bande centrale 3 de la plaque a été réalisée en encollant sur celle-ci une feuille intermédiaire supplémentaire 7', une feuille de cannelure 5' et une feuille de couverture supplémentaire 9'. With reference to the figures, a cardboard plate 1 according to the invention is rectangular and has a central strip 3 extending over its length. The central strip 3 consists of a cardboard with three grooves 5 and 5 '(Figure 2) interposed between two internal intermediate sheets 7 and 7' and covered with two external sheets 9 and 9 '. The rest of the plate 11 is formed from a cardboard box with two grooves 5 (the same as those of the central strip) comprising a single internal intermediate sheet 7 and one or two cover sheets 9 (only one is shown on the bottom) . Relative to this part 11, the central strip 3 of the plate was produced by gluing on it an additional intermediate sheet 7 ', a flute sheet 5' and an additional cover sheet 9 '.

Toutes les cannelures 5 et 5' s'étendent dans le sens de la largeur de la plaque et seront par conséquent disposées verticales sur les côtés de la caisse formée. All the grooves 5 and 5 ′ extend across the width of the plate and will therefore be arranged vertically on the sides of the box formed.

Les lignes de pli 13, en trait interrompu sur la figure 1, délimitent les 4 côtés verticaux 14 de la caisse et les segments latéraux 15 en trait plein, les flans 17 de couvercle et de fond de la caisse. Comme il apparaît sur la figure, la largeur de la bande centrale 3 est légèrement plus importante que la hauteur des côtés verticaux 14 et déborde sur les flans 17 de couvercle et de fond selon des franges 19 de faible largeur. The fold lines 13, in broken lines in FIG. 1, delimit the 4 vertical sides 14 of the box and the lateral segments 15 in solid line, the blanks 17 of the cover and of the bottom of the box. As it can be seen in the figure, the width of the central strip 3 is slightly greater than the height of the vertical sides 14 and extends over the blanks 17 of the cover and bottom according to fringes 19 of small width.

La caisse d'emballage (Figure 3) s'obtient par,décou- page des segments latéraux 15, pliage à 900 des côtés verticaux 14 de la bande centrale et rabattement des flans 17 de fond et de couvercle. Ces flans sont solidarisés en dernier lieu pour fermer la caisse. The packing case (FIG. 3) is obtained by cutting the lateral segments 15, folding the vertical sides 14 of the central strip to 900 and folding the blanks 17 at the bottom and at the cover. These blanks are joined last to close the box.

L'épaisseur et la rigidité des trois cannelures sur les côtés verticaux confèrent à ces derniers une excellente résistance mécanique verticale notamment de support des caisses superposées. Les franges 19 renforcent la rigidité des plis entre côtés verticaux et flans de fond et de couvercle, améliorent par conséquent la rigidité de la caisse et limitent le flambage dû à une poussée centrifuge du matériau. The thickness and rigidity of the three grooves on the vertical sides give them excellent vertical mechanical resistance, particularly for supporting stacked boxes. The fringes 19 reinforce the rigidity of the folds between vertical sides and bottom and cover blanks, consequently improve the rigidity of the box and limit buckling due to a centrifugal thrust of the material.

Naturellement, de nombreuses variantes de réalisation peuvent être apportées à l'invention dans le cadre des revendications présentées ci-après. Notamment, quant aux nombres de cannelures de la bande centrale et du reste de la plaque qui peuvent varier en toutes proportions.  Naturally, numerous variant embodiments can be made to the invention in the context of the claims presented below. In particular, as for the numbers of grooves in the central strip and the rest of the plate which can vary in all proportions.
