Definitions
- the present invention relates to corrugated cardboard packaging, from a single blank or from several blanks, suitably cut and creased. It relates more particularly to the assembly of parts of walls of these packages, constituted by panels arranged at the ends of the original blank, that is to say the panels of this blank which are not connected together by a line folding.
- a major drawback of this assembly system is the presence of an extra thickness equal to the thickness of the panels, both inside and outside the packaging.
- the two panels thus assembled when they lie flat on the same flat support, are not in line with one another, but are offset by a thickness of panel.
- the flat storage of packaging of this pre-assembled type leads to unstable packaging stacks and, on the other hand, that the mechanized volume setting of these packaging raises various problems.
- the mechanized introduction of batches of objects to be packaged in this packaging is thwarted by the presence of the extra thickness of the inner leg (s).
- the presence of at least one connecting tab in excess thickness at the end of the packaging detracts from the appearance of the latter.
- the grooves are certainly arranged vertically, to ensure good resistance to compression during stacking of the packages, but this technique is naturally not applicable to the assembly of parts of the panels of a package since, as it was indicated above, the corresponding portions of groove and cover of these two parts of panels to be assembled are not brought edge to edge, and that on the contrary a vacuum remains below the protruding part of cover serving assembly tab.
- the present invention is concerned with this type of assembly system, and it aims to remedy the drawbacks of the prior art by proposing a method which can be implemented using corrugated cardboard of a suitable type tional, which lends itself to the assembly between them of parts of the lateral packaging faces and which allows the realization of packaging in which the corrugated cardboard flutes can be arranged vertically.
- the subject of the invention is a method of assembling parts of the walls of a package produced from at least one blank, cut and grooved, in conventional corrugated cardboard with at least one layer of grooves, characterized in that one eliminates, along the entire length of the free edge of each of the end panels of the blank, parallel to the grooves of the corrugated cardboard, on the one hand, the contiguous part of one of the cover sheets arranged on the outside of the corrugated cardboard, and, on the other hand, the underlying internal structure thereof, leaving only part of the other external covering sheet to remain, at least at a fraction of said edge, so that '' it overflows forming a strip in the extension of the panel to which it is attached, the cover sheet whose part contiguous to said free edge remains being different for each of said end panels, so that the strips formed by the protruding parts are arranged on either side of the blank, in that the said strips and / or the corresponding parts of the opposite end panel are then glued against which they are intended to be applied,
- the removal of part of the covering and of the underlying internal structure of the corrugated cardboard, parallel or perpendicular to the grooves can be done using a sharp tool, by a laser beam. , or by any other means known in the art.
- corrugated cardboard By the term “underlying internal structure of corrugated cardboard”, we naturally designate the single flute in the case of a double-sided corrugated cardboard, the two flutes between which a middle sheet is interposed, in the case of a corrugated cardboard double double, and the three grooves and two middle sheets, in the case of a triple carton.
- the packaging produced by the method according to the invention and in which the assembly of wall parts is carried out using two connecting strips adjoining one of the panels and glued against the other panel has, of course , a much higher resistance, at the level of this assembly, than that of the usual packaging comprising only one junction tab, because double-sided bonding increases safety! of the junction.
- This method has, moreover, the advantage of practically causing no extra thickness, outside and inside the package, at the junction tabs. Admittedly, such an assembly method requires the use of cutting tools, but, on the other hand, it does not imply the use of separate joining strips of corrugated cardboard.
- the grooves of the corrugated cardboard can be parallel to the vertical edges of the packaging and thus ensure that it has optimum resistance to compression.
- Another object of the invention is therefore constituted by such a packaging from at least one blank of conventional corrugated cardboard, and parts of the same wall corresponding to the end panels of each of the blanks are secured to one another in the same plane by two strips formed by a portion of the external cover of each of said panels, projecting outside the panel to which it is attached and glued against the adjacent panel, one outside of the package and the other inside thereof, the free edges of the grooves underlying said covers being arranged substantially edge to edge and these grooves being substantially parallel to the vertical edges of the mounted packaging.
- Such packaging is particularly suitable for packaging heavy products, because of the double security provided by the glued tabs on both sides and by the vertical grooves in the corrugated cardboard.
- This method of assembly also reduces the risk of tearing or unsticking of the strips and it is therefore possible to produce joining strips of a width less than that of the single joining tabs of the cone technique.
- the two bands may also possibly cover a different width.
- the invention therefore provides a new process assembly and new packaging which have appreciable advantages over the prior art.
- Figures 1 and 2 are cross sections of the edges of two end panels of a blank of corrugated cardboard, respectively before and after bonding on the adjoining panel in order to produce a face of a package;
- Figure 3 is a perspective view of a package according to the invention, in which the free edges of the panels assembled recto-verso are, after assembly, arranged in the central part of a face of the package.
- the double-sided corrugated cardboard blank with a fluted layer used to produce the packaging shown, comprises parts of rectangular panels such as 1 and 4, the panels being attached two to two by a fold line.
- the panels 1 and 4 of the blank have a free edge parallel or perpendicular to the corrugated cardboard grooves, and it is these panels which it is desired to assemble to form one face of a package.
- Such packaging (an American box) is shown in Figure 3. It includes a longitudinal wall formed of a single: rectangular panel 23, two transverse walls 22 and 24, adjoining by a fold line to the panel 23 and provided with flaps 22 and 24 'respectively, and a second longitudinal wall resulting from the two-sided assembly, using cover strips 25 and 26, in accordance with the invention, of a panel 21, adjoining the wall 22 by a fold line, and a panel 21a adjoining the wall 24.
- cover strips 25 and 26 also bring together in this case the flaps 21, and 21'a adjoining their upper part and the lower part of panels 11 and 11 a.

Description
La présente invention concerne les emballages en carton ondulé, issus d'un flan unique ou de plusieurs flans, convenablement découpés et rainés. Elle concerne plus particulièrement l'assemblage de parties de parois de ces emballages, constituées par des panneaux disposés aux extrémités du flan d'origine, c'est-à-dire les panneaux de ce flan qui ne sont pas raccordés entre eux par une ligne de pliage.The present invention relates to corrugated cardboard packaging, from a single blank or from several blanks, suitably cut and creased. It relates more particularly to the assembly of parts of walls of these packages, constituted by panels arranged at the ends of the original blank, that is to say the panels of this blank which are not connected together by a line folding.
Dans de tels emballages, il est usuel de rendre solidaires l'un de l'autre les panneaux non attenants à l'aide d'une bande de papier collée extérieurement à l'emballage sur les parois, cette bande pouvant être soit auto-adhésive, soit encollée au moment de son application contre le carton. Pour réaliser ce mode d'assemblage, les panneaux à réunir sont repliés à plat contre les autres panneaux, de manière à se trouver bord à bord, et la bande de jonction est appliquée à plat par dessus ces panneaux.In such packages, it is customary to make the non-adjoining panels integral with one another using a strip of paper glued outside the packaging to the walls, this strip being either self-adhesive. , or glued when applied against the cardboard. To achieve this method of assembly, the panels to be joined are folded flat against the other panels, so as to be edge to edge, and the joining strip is applied flat over these panels.
Bien entendu, avec un tel procédé, une bande intérieure doublant la bande extérieure ne peut pas être appliquée simultanément sur la face interne des parois, puisque celles-ci reposent la plupart du temps à plat sur les autres panneaux. Or, pour de nombreuses utilisations, il serait souhaitable de pouvoir obtenir une liaison renforcée entre parois en doublant la bande collée extérieurement par une bande collée intérieurement.Of course, with such a method, an internal strip doubling the external strip cannot be applied simultaneously to the internal face of the walls, since these rest most of the time flat on the other panels. However, for many uses, it would be desirable to be able to obtain a reinforced bond between walls by doubling the strip glued externally by a band glued internally.
En effet, lorsqu'une seule bande externe d'assemblage est utilisée, on risque non seulement une déchirure de cette bande à partir de l'une de ses extrémités ou à partir d'une amorce de déchirure due à une faiblesse locale de cette bande, mais surtout un décollage de la bande, lorsqu'un effort de cisaillement des deux panneaux assemblés tend à soulever la bande et à l'arracher.Indeed, when a single external assembly strip is used, there is not only a risk of tearing of this strip from one of its ends or from a tear initiation due to local weakness of this strip , but above all a take-off of the strip, when a shearing effort from the two assembled panels tends to lift the strip and tear it off.
Dans son certificat d'utilité français N° 2 178 782, la Demanderesse a déjà proposé, pour éviter ces inconvénients, de réunir deux panneaux d'un emballage en carton ondulé ou similaire en collant sur chacun des panneaux une patte attenante à l'autre panneau, une patte étant collée sur la face externe de l'un des panneaux et l'autre patte sur la face interne de l'autre panneau, chaque patte étant éventuellement biseautée et amincie depuis le panneau auquel elle est attenante jusqu'à l'extrémité collée sur l'autre panneau.In its French utility certificate No. 2,178,782, the Applicant has already proposed, to avoid these drawbacks, to combine two panels of corrugated cardboard packaging or the like by gluing on each of the panels one tab attached to the other. panel, one tab being glued to the outer face of one of the panels and the other tab to the inner face of the other panel, each tab being optionally bevelled and thinned from the panel to which it is attached up to the end glued to the other panel.
Un inconvénient majeur de ce système d'assemblage est cependant la présence d'une surépaisseur égale à l'épaisseur des panneaux, tant à l'intérieur qu'à l'extérieur de l'emballage. En outre, les deux panneaux ainsi assemblés, lorsqu'ils reposent à plat sur un même support plan, ne sont pas dans le prolongement l'un de l'autre, mais sont décalés d'une épaisseur de panneau. Il en résulte, d'une part, que le stockage à plat des emballages de ce type pré-assemblés conduit à des piles d'emballages instables et, d'autre part, que la mise en volume mécanisée de ces emballages soulève divers problèmes. De même, l'introduction mécanisée de lots d'objets à conditionner dans cet emballage est contrariée par la présence de la surépaisseur de la ou des pattes intérieures. Enfin, comme dans les emballages de la technique antérieure à patte unique, la présence d'au moins une patte de jonction en surépaisseur à l'extrémité de l'emballage nuit à l'aspect de celui-ci.A major drawback of this assembly system, however, is the presence of an extra thickness equal to the thickness of the panels, both inside and outside the packaging. In addition, the two panels thus assembled, when they lie flat on the same flat support, are not in line with one another, but are offset by a thickness of panel. As a result, on the one hand, the flat storage of packaging of this pre-assembled type leads to unstable packaging stacks and, on the other hand, that the mechanized volume setting of these packaging raises various problems. Likewise, the mechanized introduction of batches of objects to be packaged in this packaging is thwarted by the presence of the extra thickness of the inner leg (s). Finally, as in the packaging of the prior art with a single tab, the presence of at least one connecting tab in excess thickness at the end of the packaging detracts from the appearance of the latter.
On a également proposé (voir US-A 3 254 827) d'utiliser un flan de carton ondulé convenablement découpé et refoulé, dans lequel l'un des panneaux du flan comporte une partie de couverture qui déborde à la manière d'une languette par rapport à la feuille cannelée ou "cannelure " et par rapport à l'autre couverture. L'assemblage de ce panneau et du panneau adjacent associé s'effectue en appliquant la partie formant languette contre la couverture correspondante du panneau associé, mais sans amener bord à bord les cannelures et les autres couvertures, de manière à pouvoir replier à 90° la partie formant languette pour former une partie de coin d'un emballage. Dans celui-ci, les cannelures sont certes disposées verticalement, pour assurer une bonne résistance à la compression lors du gerbage des emballages, mais cette technique n'est naturellement pas applicable à l'assemblage de parties de panneaux d'un emballage puisque, comme il a été indiqué ci-dessus, les portions correspondantes de cannelure et de couverture de ces deux parties de panneaux à assembler ne sont pas amenées bord à bord, et qu'au contraire un vide subsiste au-dessous de la partie débordante de couverture servant de languette d'assemblage.It has also been proposed (see US-A 3,254,827) to use a blank of corrugated cardboard suitably cut and pushed back, in which one of the panels of the blank has a covering part which projects in the manner of a tongue by compared to the fluted sheet or "flute" and compared to the other cover. The assembly of this panel and of the associated adjacent panel is carried out by applying the tongue-forming part against the corresponding cover of the associated panel, but without bringing the grooves and the other covers edge to edge, so as to be able to fold back at 90 ° the tab portion to form a corner portion of a package. In this one, the grooves are certainly arranged vertically, to ensure good resistance to compression during stacking of the packages, but this technique is naturally not applicable to the assembly of parts of the panels of a package since, as it was indicated above, the corresponding portions of groove and cover of these two parts of panels to be assembled are not brought edge to edge, and that on the contrary a vacuum remains below the protruding part of cover serving assembly tab.
On a par ailleurs proposé (voir GB-A 384 794 et US-A 1 845 891) de partir de panneaux de carton ondulé dans lesquels une feuille de couverture déborde latéralement d'un côté, par rapport à la feuille cannelée ou "cannelure" du carton ondulé, tandis que la seconde couverture déborde latéralement de l'autre côté. Les flans de carton, découpés et refoulés, destinés à la réalisation d'un conditionnement sont découpés dans ces panneaux de carton ondulé obliquement par rapport aux cannelures et on les assemble au moins partiellement, après mise en forme, en amenant bord à bord les parties latérales des panneaux, de manière que chaque partie débordante de chaque couverture vienne s'appliquer sur la couverture de la partie contiguë contre laquelle elle est collée.It has also been proposed (see GB-A 384 794 and US-A 1 845 891) to start from corrugated panels in which a cover sheet projects laterally on one side, relative to the fluted sheet or "flute" corrugated cardboard, while the second cover projects laterally on the other side. The cardboard blanks, cut and turned back, intended for the realization of a packaging are cut in these corrugated cardboard panels obliquely relative to the grooves and they are assembled at least partially, after shaping, bringing the parts edge to edge lateral of the panels, so that each projecting part of each cover comes to apply on the cover of the contiguous part against which it is glued.
Cette technique présente toutefois deux inconvénients sérieux, qui ont empêché de l'utiliser sur une large échelle:
- - d'une part, elle nécessite l'emploi de cartons spéciaux, dont les couvertures débordent latéralement par rapport à la cannelure, et non d'un carton conventionnel, dont les couvertures ne débordent pas en dehors de la cannelure;
- - d'autre part, le conditionnement réalisé à partir de tels cartons présente une résistance médiocre à la compression, du fait de la position oblique des cannelures par rapport aux arêtes verticales du conditionnement.
- - On the one hand, it requires the use of special cartons, the covers of which extend laterally with respect to the groove, and not of a conventional carton, the covers of which do not protrude outside the groove;
- - On the other hand, the packaging made from such cartons has poor resistance to compression, due to the oblique position of the grooves relative to the vertical edges of the packaging.
C'est à ce type de système d'assemblage que s'intéresse la présente invention, et elle vise à remédier aux inconvénients de la technique antérieure en proposant un procédé qui puisse être mis en oeuvre à l'aide de carton ondulé d'un type conventionnel, qui se prête à l'assemblage entre elles de parties de faces latérales de conditionnement et qui permette la réalisation de conditionnements dans lesquels les cannelures du carton ondulé puissent être disposées verticalement.The present invention is concerned with this type of assembly system, and it aims to remedy the drawbacks of the prior art by proposing a method which can be implemented using corrugated cardboard of a suitable type tional, which lends itself to the assembly between them of parts of the lateral packaging faces and which allows the realization of packaging in which the corrugated cardboard flutes can be arranged vertically.
A cet effet, l'invention a pour objet un procédé d'assemblage de parties de parois d'un emballage réalisé à partir d'au moins un flan, découpé et rainé, en un carton ondulé conventionnel à au moins une couche de cannelures, caractérisé en ce que l'on élimine, suivant toute la longueur du bord libre de chacun des panneaux d'extrémité du flan, parallèlement aux cannelures du carton ondulé, d'une part, la partie contiguë de l'une des feuilles de couverture disposées à l'extérieur du carton ondulé, et, d'autre part, la structure interne sous-jacente de celuici, en laissant seulement subsister, suivant une fraction au moins dudit bord, une partie de l'autre feuille externe de couverture, afin qu'elle déborde en formant une bande dans le prolongement du panneau auquel elle est attenante, la feuille de couverture dont la partie contiguë audit bord libre subsiste étant différente pour chacun desdits panneaux d'extrémité, de façon que les bandes constituées par les parties débordantes soient disposées de part et d'autre du flan, en ce que l'on encolle ensuite lesdites bandes et/ou les parties correspondantes du panneau d'extrémité opposé contre lesquelles elles sont destinées à être appliquées, et en ce que l'on amène en contact lesdites bandes contre lesdites parties correspondantes des panneaux d'extrémité opposés, en amenant simultanément bord à bord les tranches libres des cannelures desdits panneaux d'extrémité.To this end, the subject of the invention is a method of assembling parts of the walls of a package produced from at least one blank, cut and grooved, in conventional corrugated cardboard with at least one layer of grooves, characterized in that one eliminates, along the entire length of the free edge of each of the end panels of the blank, parallel to the grooves of the corrugated cardboard, on the one hand, the contiguous part of one of the cover sheets arranged on the outside of the corrugated cardboard, and, on the other hand, the underlying internal structure thereof, leaving only part of the other external covering sheet to remain, at least at a fraction of said edge, so that '' it overflows forming a strip in the extension of the panel to which it is attached, the cover sheet whose part contiguous to said free edge remains being different for each of said end panels, so that the strips formed by the protruding parts are arranged on either side of the blank, in that the said strips and / or the corresponding parts of the opposite end panel are then glued against which they are intended to be applied, and in that the said strips are brought into contact against said corresponding parts of the opposite end panels, simultaneously bringing edge to edge the free edges of the grooves of said end panels.
Comme on le verra ci-après, après montage de l'emballage, les bords contigus desdits panneaux ainsi assemblés sont disposés dans le plan d'une face de l'emballage.As will be seen below, after assembly of the packaging, the contiguous edges of said panels thus assembled are arranged in the plane of one face of the packaging.
On notera que l'on part d'un flan en un carton ondulé d'un type classique et que c'est sur ce flan prédécoupé que l'on effectue une opération d'élimination de matière.It will be noted that one starts from a blank of corrugated cardboard of a conventional type and that it is on this precut blank that a material removal operation is carried out.
Selon l'invention, l'élimination d'une partie de la couverture et de la structure interne sous-jacente du carton ondulé, parallèlement ou perpendiculairement aux cannelures, peut se faire à l'aide d'un outil tranchant, par un faisceau laser, ou par tout autre moyen connu dans la technique.According to the invention, the removal of part of the covering and of the underlying internal structure of the corrugated cardboard, parallel or perpendicular to the grooves, can be done using a sharp tool, by a laser beam. , or by any other means known in the art.
Par le terme "structure interne sous-jacente du carton ondulé", on désigne naturellement la cannelure unique dans le cas d'un carton ondulé double face, les deux cannelures entre lesquelles est interposée une feuille médiane, dans le cas d'un carton ondulé double double, et les trois cannelures et deux feuilles médianes, dans le cas d'un carton triple.By the term "underlying internal structure of corrugated cardboard", we naturally designate the single flute in the case of a double-sided corrugated cardboard, the two flutes between which a middle sheet is interposed, in the case of a corrugated cardboard double double, and the three grooves and two middle sheets, in the case of a triple carton.
L'encollage des bandes formées par les parties de couverture externe débordant des panneaux d'extrémité du flan et leur application contre le panneau opposé s'effectuent à l'aide de machines classiques.The strips formed by the external covering parts projecting from the end panels of the blank are glued and applied against the opposite panel using conventional machines.
L'emballage réalisé par le procédé selon l'invention et dans lequel l'assemblage de parties de parois est réalisé à l'aide de deux bandes de jonction attenantes à l'un des panneaux et collées contre l'autre panneau a, bien entendu, une résistance bien supérieure, au niveau de cet assemblage, à celle des emballages usuels ne comportant qu'une patte de jonction, car le collage recto-verso augmente la sécurité! de la jonction.The packaging produced by the method according to the invention and in which the assembly of wall parts is carried out using two connecting strips adjoining one of the panels and glued against the other panel has, of course , a much higher resistance, at the level of this assembly, than that of the usual packaging comprising only one junction tab, because double-sided bonding increases safety! of the junction.
Ce procédé présente, en outre, l'avantage de n'entraîner pratiquement aucune surépaisseur, à l'extérieur et à l'intérieur de l'emballage, au niveau des pattes de jonction. Certes, un tel mode d'assemblage nécessite l'emploi d'outils coupants, mais, en revanche, il n'implique pas l'utilisation de bandes de jonction distinctes du carton ondulé.This method has, moreover, the advantage of practically causing no extra thickness, outside and inside the package, at the junction tabs. Admittedly, such an assembly method requires the use of cutting tools, but, on the other hand, it does not imply the use of separate joining strips of corrugated cardboard.
Enfin, dans l'emballage monté, les cannelures du carton ondulé peut être parallèles aux arêtes verticales de l'emballage et assurer ainsi à celui-ci une résistance optimum à la compression, Un autre objet de l'invention est donc constitué par un tel emballage issu d'au moins un flan de carton ondulé conventionnel et dont des parties d'une même paroi correspondant aux panneaux d'extrémité de chacun des flans sont solidaires l'une de l'autre dans un même plan par deux bandes constituées par un portion de la couverture externe de chacun desdits panneaux, débordant en dehors du panneau auquel elle est attenante et collée contre le panneau adjacent, l'une à l'extérieur de l'emballage et l'autre à l'intérieur de celui-ci, les tranches libres des cannelures sous-jacentes auxdites couvertures étant disposées sensiblement bord à bord et ces cannelures étant sensiblement parallèles aux arêtes verticales de l'emballage monté.Finally, in the mounted packaging, the grooves of the corrugated cardboard can be parallel to the vertical edges of the packaging and thus ensure that it has optimum resistance to compression. Another object of the invention is therefore constituted by such a packaging from at least one blank of conventional corrugated cardboard, and parts of the same wall corresponding to the end panels of each of the blanks are secured to one another in the same plane by two strips formed by a portion of the external cover of each of said panels, projecting outside the panel to which it is attached and glued against the adjacent panel, one outside of the package and the other inside thereof, the free edges of the grooves underlying said covers being arranged substantially edge to edge and these grooves being substantially parallel to the vertical edges of the mounted packaging.
Un tel emballage est particulièrement approprié au conditionnement de produits lourds, du fait de la double sécurité apportée par les pattes collées recto-verso et par les cannelures verticales du carton ondulé.Such packaging is particularly suitable for packaging heavy products, because of the double security provided by the glued tabs on both sides and by the vertical grooves in the corrugated cardboard.
Ce mode d'assemblage diminue en outre les risques d'arrachement ou de décollage des bandes et l'on peut donc réaliser des bandes de jonction d'une largeur moindre que celle des pattes de jonction uniques de la technique conne. Les deux bandes pourront d'ailleurs couvrir éventuellement une largeur différente.This method of assembly also reduces the risk of tearing or unsticking of the strips and it is therefore possible to produce joining strips of a width less than that of the single joining tabs of the cone technique. The two bands may also possibly cover a different width.
L'absence de surépaisseur au niveau de la jonction permet de stocker à plat les emballages préas- semblés, en formant des piles parfaitement stables, sans que les pattes externes d'un emballage viennent poinçonner, en l'affaiblissant, la face externe d'un autre emballage avec lequel il est en contact dans la pile. Les emballages ainsi disposés à plat et non déformés se prêtent parfaitement à une mise en volume mécanisée.The absence of extra thickness at the junction makes it possible to store the pre-assembled packages flat, forming perfectly stable stacks, without the outer tabs of a package puncturing, weakening, the outer face of another package with which it is in contact in the stack. The packages thus arranged flat and not deformed lend themselves perfectly to mechanized volume setting.
En outre, les essais effectués en France auprès du Laboratoire National d'Essais sur des caisses dites américaines (essai de résistance à la compression dynamique des caisses selon la norme NF H 13001; essais de chocs au tambour culbuteur selon la norme NF H 00057) ont montré, de façon inattendue, que les emballages conformes à l'invention ont des performances supérieures à celles des emballages assemblés de façon usuelle.In addition, the tests carried out in France at the National Laboratory for Testing on so-called American bodies (test of resistance to dynamic compression of the bodies according to standard NF H 13001; impact tests on the tumbler drum according to standard NF H 00057) have shown, unexpectedly, that the packaging according to the invention has higher performance than that of packaging assembled in the usual manner.
Enfin, l'introduction mécanique dans l'emballage des objets à conditionner est notablement facilitée par l'absence de surépaisseur sur les parois internes.Finally, the mechanical introduction into the packaging of the objects to be packaged is notably facilitated by the absence of additional thickness on the internal walls.
L'invention apporte donc un nouveau procédé d'assemblage et un nouvel emballage qui présentent des avantages appréciables par rapport à la technique antérieure.The invention therefore provides a new process assembly and new packaging which have appreciable advantages over the prior art.

Comme on le voit sur les figures 1 et 2, le flan de carton ondulé double face et à une couche cannelée, utilisé pour réaliser l'emballage représenté, comprend des parties de panneaux rectangulaires telles que 1 et 4, les panneaux étant attenants deux à deux par une ligne de pliage.As can be seen in FIGS. 1 and 2, the double-sided corrugated cardboard blank with a fluted layer, used to produce the packaging shown, comprises parts of rectangular panels such as 1 and 4, the panels being attached two to two by a fold line.
Les panneaux 1 et 4 du flan ont un bord libre parallèle ou perpendiculaire aux cannelures de carton ondulé, et ce sont ces panneaux que l'on désire assembler pour former une face d'un emballage.The panels 1 and 4 of the blank have a free edge parallel or perpendicular to the corrugated cardboard grooves, and it is these panels which it is desired to assemble to form one face of a package.
Dans ce but, conformément à l'invention, on commence par éliminer, à l'aide d'un outi-I tranchant, d'un faisceau laser ou d'un moyen analogue, suivant le bord libre des panneaux 1 et 4 et parallèlement aux cannelures de celui-ci, une partie de l'une des couvertures du carton ondulé et de la cannelure sousjacente, à savoir une partie de la couverture 11, destinée à être à l'extérieur de la caisse, pour le panneau 1, et une partie de la couverture 12, destinée à être à l'intérieur de la caisse pour Le panneau 4, et la partie de la cannelure 13 située au-dessous des parties de cannelure éliminées, Il ne subsiste ainsi, au niveau du bord libre de chacun des panneaux, qu'une bande de la couverture qui n'a pas été éliminée, à savoir une bande 12a prolongeant la couverture 12 pour le panneau 4, et une bande 11a prolongeant la couverture 11 pour le panneau 1.For this purpose, in accordance with the invention, we begin by eliminating, using a sharp tool, a laser beam or the like, along the free edge of the panels 1 and 4 and in parallel to the grooves thereof, part of one of the covers of the corrugated cardboard and of the underlying groove, namely a part of the
Après avoir encollé la face interne de ces bandes et/ou les parties du panneau contigu contre lesquelles elles sont destinées à être collées, il suffit d'amener bord à bord les cannelures des panneaux 1 et 4 pour les assembler recto-verso par collage des bandes 11 a et 12a contre les panneaux contigus.After having glued the internal face of these strips and / or the parts of the contiguous panel against which they are intended to be glued, it suffices to bring edge to edge the grooves of panels 1 and 4 to assemble them back-to-back by gluing the
On obtient ainsi des faces d'emballage constituées par les panneaux assemblés qui ne présentent pratiquement aucune surépaisseur, ni à l'intérieur, ni à l'extérieur de la caisse, et dont les cannelures peuvent être disposées en position verticale.One thus obtains packaging faces constituted by the assembled panels which have practically no allowance, either inside or outside the box, and whose grooves can be arranged in a vertical position.
Un tel emballage (une caisse américaine) est représenté sur la figure 3. Il comprend une paroi longitudinale formée d'un unique: panneau rectangulaire 23, deux parois transversales 22 et 24, attenantes par une ligne de pliage au panneau 23 et munies de volets respectivement 22, et 24', et une seconde paroi longitudinale résultant de l'assemblage recto-verso, à l'aide de bandes de couverture 25 et 26, conformément à l'invention, d'un panneau 21, attenant à la paroi 22 par une ligne de pliage, et d'un panneau 21 a attenant à la paroi 24. Bien entendu, les bandes de couvertures 25 et 26 réunissent également dans ce cas les volets 21, et 21'a attenants à -leur partie supérieure et à la partie inférieure aux panneaux 11 et 11 a.Such packaging (an American box) is shown in Figure 3. It includes a longitudinal wall formed of a single:
Il va de soi que le même procédé d'assemblage peut être utilisé avec des cartons ondulés ayant plus d'une couche cannelée.It goes without saying that the same assembly process can be used with corrugated cardboard having more than one corrugated layer.
Dans tous les cas, le fait que les cannelures sont disposées parallèlement aux arêtes verticales de celui-ci renforce considérablement sa résistance à la compression, Ainsi qu'il a été mentionné ci-dessus, les caisses ainsi réalisées se prêtent à un stockage à plat et à une mise en volume mécanisée. Bien entendu, l'invention n'est pas limitée aux seules caisses américaines, mais elle peut s'appliquer à tout type d'emballage dans lequel des parois d'extrémité doivent être jointes l'une à l'autre, et ayant les formes les plus variables telles que parallélépipédique, hexagonale, circulaire, etc.In all cases, the fact that the grooves are arranged parallel to the vertical edges of the latter considerably reinforces its resistance to compression. As mentioned above, the cases thus produced lend themselves to flat storage. and a mechanized volume setting. Of course, the invention is not limited to American boxes only, but it can be applied to any type of packaging in which end walls must be joined to each other, and having the forms the most variable such as parallelepiped, hexagonal, circular, etc.
