Description

La présente invention concerne les boîtes d'emballage réalisées à partir d'un flan découpé dans une feuille d'un matériau semi-rigide telle que du carton. Ces boîtes sont formées par plage à partir du flan découpé, par emboîtement des différentes pattes du flan et éventuellement par collage d'une patte d'extrémité contre une face adjacente de la paroi de la boîte.The present invention relates to packaging boxes made from a blank cut from a sheet of a semi-rigid material such as cardboard. These boxes are formed by pads from the cut blank, by fitting the different tabs of the blank and optionally by bonding an end tab against an adjacent face of the wall of the box.

L'invention concerne plus particulièrement de telles boîtes munies d'un chemisage interne généralement en papier, destinée à améliorer la présentation des objets se trouvant dans la boîte.The invention relates more particularly to such boxes provided with an internal liner generally made of paper, intended to improve the presentation of the objects found in the box.

Habituellement, la paroi de chemisage est découpée indépendamment du flan de carton destiné à constituer la paroi externe de la boîte.Usually, the lining wall is cut independently of the cardboard blank intended to constitute the outer wall of the box.

Lorsque la boîte est mise en forme par pliage et emboîtement des différentes pattes du flan découpé, on installe alors dans la boîte la paroi de chemisage et dans certains cas, on la colle sur la face interne de la boîte en laissant toutefois libre les pattes supérieures du flan de chemisage. Cela permet, lors de la fermeture de la boîte d'emballage qui a été préalablement remplie des marchandises à emballer, de fermer en premier les rabats de chemisage et de terminer la fermeture de la boîte par le rabattement des pattes de la paroi externe.When the box is shaped by folding and interlocking of the different tabs of the cut blank, the lining wall is then installed in the box and in some cases, it is glued to the internal face of the box, however leaving the upper tabs free liner blank. This allows, when closing the packaging box which has been previously filled with the goods to be packaged, to close the liner flaps first and to complete the closing of the box by folding down the tabs of the external wall.

Ce procédé connu de fabrication de boîte chemisée présente l'inconvénient de nécessiter de la main d'oeuvre pour effectuer la mise en place et le collage du chemisage dans l'ébauche constituée par la paroi de la boîte.This known method of manufacturing a lined box has the drawback of requiring labor to carry out the fitting and bonding of the liner in the blank formed by the wall of the box.

On connaît selon le US-A-3 590 699 un procédé pour fabriquer des boîtes d'emballage dans lequel on col le deux feuilles l'une à l'autre, suivant deux bandes d'encollage s'étendant le long des deux bords longitudinaux.According to US-A-3 590 699, a process is known for manufacturing packaging boxes in which the two sheets are stuck together, according to two gluing strips extending along the two longitudinal edges. .

Les rabats et pattes repliables se trouvent ainsi encollés l'un à l'autre dans les parties supérieures et inférieures.The foldable flaps and legs are thus glued to each other in the upper and lower parts.

L'invention a notamment pour but de remédier aux inconvénients ci-dessus et de proposer un procédé de fabrication de boîtes munies d'un chemisage, qui soit facilement automatisable.The object of the invention is in particular to remedy the above drawbacks and to propose a method for manufacturing boxes provided with a liner, which is easily automated.

Ce but est atteint, conformément à l'invention, du fait que le procédé de fabrication d'une boîte d'emballage comportant des pattes supérieures et munie d'un chemisage comportant des rabats supérieurs indépendants des pattes supérieures, du type selon lequel on réalise un flan découpé et on met en forme la boîte par plage et par emboîtement des différents pattes dudit flan les unes dans les autres, est caractérisé en ce que l'on encolle partiellement sur l'une de ses faces, une première feuille sur une partie longitudinale et marginale comprise entre l'un des bords longitudinaux de la feuille et une ligne située à une certaine distance de l'autre bord longitudinal de la feuille, correspondant sensiblement à la ligne de plage des rabats et des pattes supérieures. On applique cette feuille par sa face encollée sur une deuxième feuille et on découpe la feuille complexe ainsi obtenue, selon la ligne de découpage du flan destiné à former la boîte d'emballage, le découpage des rabats supérieurs dans la première feuille et celui des pattes supérieures dans la deuxième feuille étant réalisé dans la partie des deux feuilles qui n'est pas encollée, de manière à laisser lesdits rabats indépendants desdites pattes.This object is achieved, in accordance with the invention, by the fact that the method of manufacturing a packaging box comprising upper tabs and provided with a liner comprising upper flaps independent of the upper legs, of the type according to which a cut blank is produced and the box is shaped by range and by interlocking of the different legs of said blank one inside the other, is characterized in that it is partially glued onto the one of its faces, a first sheet on a longitudinal and marginal part lying between one of the longitudinal edges of the sheet and a line situated at a certain distance from the other longitudinal edge of the sheet, corresponding substantially to the beach line flaps and upper legs. This sheet is applied by its glued side on a second sheet and the complex sheet thus obtained is cut, according to the cutting line of the blank intended to form the packaging box, the cutting of the upper flaps in the first sheet and that of the legs upper in the second sheet being made in the part of the two sheets which is not glued, so as to leave said flaps independent of said tabs.

Grâce à ce procédé à l'endroit des pattes supérieures du flan, les feuilles superposées ne sont pas collées entre elles de sorte que l'on obtient bien , par ce procédé, une boîte d'emballage conforme à la description donnée ci-dessus.Thanks to this process at the location of the upper legs of the blank, the superposed sheets are not glued together so that a packaging box conforming to the description given above is obtained.

Avantageusement, la première feuille est réalisée en papier et la deuxième feuille est réalisée en carton.Advantageously, the first sheet is made of paper and the second sheet is made of cardboard.

D'autres avantages et caractéristiques de l'invention ressortiront à la lecture de la description qui va suivre de deux modes de réalisation de l'invention, description faite en référence aux dessins annexés sur lesquels :

  • la figure 1 est une vue schématique en élévation d'une installation de fabrication de boîtes d'emballage selon un mode de réalisation de l'invention ;
  • la figure 2 est une vue partielle en plan d'une bande de paroi de chemisage encollée ;
  • la figure 3 est une vue partiel le en plan de la bande complexe formée de la superposition de la bande de papier et de la bande de carton mises en oeuvre dans l'installation de la figure 1; et
  • la figure 4 est une vue en plan d'un flan découpé dans l'ensemble formé par les deux bandes superposées.
Other advantages and characteristics of the invention will emerge on reading the following description of two embodiments of the invention, description made with reference to the accompanying drawings in which:
  • Figure 1 is a schematic elevational view of an installation for manufacturing packaging boxes according to one embodiment of the invention;
  • FIG. 2 is a partial plan view of a strip of glued lining wall;
  • Figure 3 is a partial plan view of the complex strip formed by the superposition of the strip paper and cardboard strip used in the installation of Figure 1; and
  • Figure 4 is a plan view of a blank cut from the assembly formed by the two overlapping strips.

L'installation représentée sur la figure 1 comprend un rouleau de paroi en carton 1 et une rouleau de paroi de chemisage, par exemple en papier 2.The installation shown in FIG. 1 comprises a cardboard wall roller 1 and a lining wall roller, for example made of paper 2.

La bande de papier 2a qui est déroulée à partir du rouleau 2 est encollée au moyen d'un rouleau encolleur 3 d'axe horizontal et dont la partie inférieure baigne dans de la colle contenue dans un bac 4.The paper strip 2a which is unwound from the roll 2 is glued by means of a glue roller 3 with a horizontal axis and the lower part of which is bathed in glue contained in a tray 4.

La bande de papier 2a encollée est alors appliquée sur une bande de carton la déroulée à partir du rouleau 1. Cette application est réalisée entre deux rouleaux de pressage 5 et 6.The glued paper strip 2a is then applied to a cardboard strip unwound from the roll 1. This application is carried out between two pressing rollers 5 and 6.

L'ensemble formé par les bandes 1a et 2a appliquées l'une sur l'autre, constitue une bande complexe 7 qui passe ensuite dans un poste de découpage 8, de conception connue , qui est représenté schématiquement sur la figure 1 par un cadre pointillé.The assembly formed by the bands 1a and 2a applied one on the other, constitutes a complex band 7 which then passes through a cutting station 8, of known design, which is represented diagrammatically in FIG. 1 by a dotted frame .

Comme on peut le voir sur la figure 2, la bande de papier 2a n'est encollée par le rouleau 3 que sur une partie longitudinale et marginale 9, le reste de la surface de la bande 2a n'étant pas revêtu de colle.As can be seen in FIG. 2, the paper strip 2a is only glued by the roller 3 on a longitudinal and marginal part 9, the rest of the surface of the strip 2a not being coated with glue.

Dans la machine de découpage 8 de la figure 1, la bande complexe 7 est découpée selon une ligne de découpage telle que celle qui est représentée en traits d'axe et désignée par la référence 10 sur la figure 3.In the cutting machine 8 of FIG. 1, the complex strip 7 is cut along a cutting line such as that which is represented in center lines and designated by the reference 10 in FIG. 3.

Selon l'exemple représenté, cette ligne de découpage est celle d'un flan permettant d'obtenir une boîte ayant la forme d'un parallélépipède tronqué inversé, boîte qui est généralement désignée par le terme de "ballotin".According to the example shown, this cutting line is that of a blank making it possible to obtain a box having the shape of an inverted truncated parallelepiped, a box which is generally designated by the term "ballotin".

La figure 4 représente le flan découpé destiné à former cette boîte.FIG. 4 represents the cut blank intended to form this box.

Comme on peut le voir sur les figures 2 à 4, les pattes supérieures 11 et 12 du flan s'étendent entièrement sur la zone 13 non encollée de la bande de papier 2a.As can be seen in Figures 2 to 4, the upper tabs 11 and 12 of the blank extend entirely over the area 13 not glued from the paper strip 2a.

Sur la figure 2, on a représenté deux variantes de réalisation de la zone encollée 9.In FIG. 2, two alternative embodiments of the glued area 9 are shown.

Selon une première variante, les zones encollées 9 et non encollées 13 sont délimitées par une ligne droite 14 parallèle aux bords de la bande 2a.According to a first variant, the glued 9 and non-glued zones 13 are delimited by a straight line 14 parallel to the edges of the strip 2a.

Selon un deuxième mode de réalisation, les zones 9 et 13 sont délimitées par une ligne brisée 15 qui coïncide avec la ligne 14 en des endroits 16 régulièrement espacés le long de la bande 2a, et qui forme entre ces endroits 16 des segments 17 coïncidant avec les lignes de pliage 11a et 12a des pattes supérieures du flan destiné à constituer la boîte (voir figure 4).According to a second embodiment, the zones 9 and 13 are delimited by a broken line 15 which coincides with the line 14 at places 16 regularly spaced along the strip 2a, and which forms between these places 16 segments 17 coinciding with the fold lines 11a and 12a of the upper legs of the blank intended to constitute the box (see FIG. 4).

L'encollage partiel de la face inférieure de la bande de papier 2a est obtenu grâce à l'utilisation d'un rouleau 3 dont le pourtour est muni d'une réserve sur une zone partielle de ce pourtour de ce rouleau. Cette zone de réserve détermine, par sa forme, celle de la zone encollée 9 de la bande 2a.The partial gluing of the underside of the paper strip 2a is obtained by the use of a roller 3, the periphery of which is provided with a reserve on a partial zone of this periphery of this roller. This reserve zone determines, by its shape, that of the glued zone 9 of the strip 2a.
