Abstract

The package is made from an outer layer (1) e.g. of cardboard, cut out and folded to make a number of panels (7 - 10) and flaps (6) that form a container, and an inner layer (2, 3), e.g. of corrugated cardboard, wood, plastic or other material that acts as a wedge for the contents of the container. Before folding the outer layer at least part of any inner layer components is affixed to its panels, so that the inner layer is inside the package once it is made up.

Description

La présente invention concerne un procédé de réalisation d'un produit d'emballage, et plus particulièrement d'un tel produit comportant un premier flan muni d'une pluralité de panneaux et de pattes, ledit premier flan étant apte, après pliage, à former un étui pour un contenu à emballer, et au moins un deuxième flan agencé pour être logé à l'intérieur dudit étui pour caler ledit contenu.The present invention relates to a method for producing a packaging product, and more particularly such a product comprising a first blank provided with a plurality of panels and of legs, said first blank being suitable, after folding, for form a case for contents to be packaged, and at least one second blank arranged to be housed inside said case to wedge said content.

On connaít déjà des produits d'emballage de ce type réalisés à partir de deux flans, par exemple en carton.We already know packaging products of this type made from two blanks, for example of cardboard.

Dans un premier mode de réalisation connu, par exemple par le document FR-A-2 731 682, le deuxième flan est réalisé d'une seule pièce avec le premier flan. En d'autres termes, le produit d'emballage est réalisé à partir d'un flan unique dont, après pliage, certaines parties forment l'étui tandis que d'autres parties se retrouvent à l'intérieur de l'étui pour former les moyens de calage.In a first known embodiment, for example by document FR-A-2 731 682, the second blank is produced in one piece with the first blank. In other words, the packaging product is made from a single blank which, after folding, some parts form the case while other parts are found inside the case to form the wedging means.

Ce premier mode de réalisation présente l'inconvénient que les moyens de calage sont réalisés à partir d'un flan présentant les mêmes caractéristiques que celles de l'étui . Le matériau est le même, de même que ses caractéristiques mécaniques. Ceci n'est pas satisfaisant, en particulier lorsque les moyens de calage doivent également servir de renfort.This first embodiment has the disadvantage that the wedging means are made from a blank having the same characteristics as those of the case. The material is the same, as are its characteristics mechanical. This is unsatisfactory, especially when the wedging means must also serve as reinforcement.

Dans un autre mode de réalisation connu, le flan destiné à former les moyens de calage est indépendant du flan servant à réaliser l'étui . On connaít par exemple de tels produits dans lesquels l'étui est en carton compact tandis que les moyens de calage sont en carton ondulé destiné en particulier à rigidifier l'ensemble pour améliorer sa longévité. In another known embodiment, the blank intended for forming the wedging means is independent of the blank used to make the case. We know for example such products in which the case is made of compact cardboard while the wedging means are made of corrugated cardboard intended in particular to stiffen the assembly to improve its longevity.

L'inconvénient est alors que le montage du produit est plus délicat puisqu'il nécessite le montage séparé de l'étui et des moyens de calage, puis la mise en place de ces moyens de calage dans l'étui. Les moyens de calage peuvent alors ne pas être positionnés avec la précision requise dans l'étui. En outre, ce positionnement peut nécessiter des ajouts de matière qui n'ont pas d'autre fonction.The downside is that the mounting of the product is more delicate since it requires separate mounting of the case and wedging means, then the establishment of these means of wedging in the case. The timing means may then not not be positioned with the required precision in the case. In in addition, this positioning may require additions of matter which have no other function.

La présente invention vise à palier ces inconvénients.The present invention aims to overcome these drawbacks.

Plus particulièrement, l'invention a pour but de fournir un produit d'emballage et son procédé de fabrication dont résultent une plus grande facilité de montage, une meilleure souplesse d'utilisation ainsi qu'une économie de matériau.More particularly, the invention aims to provide a packaging product and its manufacturing process including the result is greater ease of assembly, better flexibility of use as well as saving material.

A cet effet l'invention a pour objet un procédé de réalisation d'un produit d'emballage comportant un premier flan muni d'une pluralité de panneaux et de pattes, ledit premier flan étant apte, après pliage, à former un étui pour un contenu à emballer, et au moins un deuxième flan agencé pour être logé à l'intérieur dudit étui pour former des moyens de calage pour ledit contenu, ce procédé comprenant une étape consistant, avant pliage dudit premier flan, à solidariser au moins une partie de chacun desdits deuxième flans à au moins un panneau et/ou une patte dudit premier flan.To this end, the subject of the invention is a method of making a packaging product comprising a first blank provided a plurality of panels and legs, said first blank being able, after folding, to form a case for content to be pack, and at least one second blank arranged to be housed inside said case to form wedging means for said content, this method comprising a step consisting in, before folding said first blank, to secure at least one part of each of said second blanks with at least one panel and / or a tab of said first blank.

Un premier avantage de l'invention réside dans les économies réalisées lors de son utilisation. Lors du conditionnement il peut en effet être utilisé sur des machines automatiques, les utilisateurs n'ayant plus qu'une seule pièce à manipuler. Il n'est en outre pas nécessaire d'ajouter d'élément de calage, ce qui simplifie le fonctionnement de la ligne de conditionnement. Par ailleurs, les utilisateurs n'ont plus qu'une seule référence à gérer, les moyens de calage et l'étui étant solidaires.A first advantage of the invention lies in the savings made during its use. When packaging it can indeed be used on automatic machines, users with only one part left to handle. he furthermore, no wedging element is necessary, which simplifies the operation of the line conditioning. In addition, users no longer have only one reference to manage, the timing means and the case being united.

Un autre avantage est la souplesse d'utilisation de ce produit d'emballage. Les moyens de calage peuvent en effet être répartis en plusieurs flans distincts à l'intérieur de l'étui. Ces flans distincts peuvent être réalisés dans des matériaux différents pouvant présenter chacun des caractéristiques mécaniques adaptées à leur fonction propre.Another advantage is the flexibility of use of this product packaging. The timing means can indeed be distributed in several distinct blanks inside the case. These separate blanks can be made of materials different, each with characteristics mechanical adapted to their own function.

Il est en outre possible de placer les moyens de calage aux endroits correspondant aux zones sensibles de détérioration lors des transports et manipulations. La consommation de matière est inférieure à celle d'un calage ordinaire du fait du positionnement partiel en un ou plusieurs éléments. Le calage à l'aide d'un produit selon l'invention est par exemple plus économique qu'un calage en carton ondulé qui a la même hauteur que l'étui et qui recouvre toutes les parois. Il en résulte moins de chutes de matière.It is also possible to place the wedging means at the places corresponding to sensitive areas of deterioration during transport and handling. The consumption of material is less than that of an ordinary setting because of the partial positioning in one or more elements. The timing using a product according to the invention is for example more economical than a corrugated cardboard shim which has the same height than the case and which covers all the walls. It results in less material falling.

Lorsque les deux flans sont réalisés dans des matériaux du même type, par exemple un carton compact et un carton ondulé, le produit peut être facilement recyclé.When the two blanks are made of materials of the same type, for example a compact carton and a carton corrugated, the product can be easily recycled.

Dans un mode de mise en oeuvre particulier du procédé selon l'invention, dans lequel au moins un desdits deuxièmes flans est composé d'une pluralité de panneaux aptes à former, après pliage, un volume de calage à l'intérieur dudit étui, ce procédé comprend une étape de pliage en une seule opération desdits premier et deuxième flans. In a particular embodiment of the method according to the invention, wherein at least one of said second blanks is composed of a plurality of panels capable of forming, after folding, a wedging volume inside said case, this method includes a folding step in a single operation said first and second blanks.

Ladite partie de chacun desdits deuxièmes flans peut notamment être solidarisée à un seul panneau ou une seule patte dudit premier flan.Said part of each of said second blanks can in particular be secured to a single panel or a single leg of said first blank.

Ainsi, si un tel deuxième flan est composé de plusieurs panneaux, ceux-ci peuvent se replier d'eux-mêmes lors du pliage du premier flan.So, if such a second blank is composed of several panels, these can fold up themselves when folding of the first blank.

Selon un autre aspect de l'invention celle-ci a pour objet un produit d'emballage réalisé par un procédé tel que décrit ci-dessus.According to another aspect of the invention, its subject is a packaging product produced by a process as described above.

Plus particulièrement, au moins un desdits deuxièmes flans peut comprendre un panneau unique doublant sensiblement et étant solidarisé à un panneau dudit premier flan.More particularly, at least one of said second blanks may include a single panel substantially doubling and being secured to a panel of said first blank.

Dans un autre mode de réalisation, au moins un desdits deuxièmes flans comprend une pluralité de panneaux dont un est solidarisé à un des panneaux dudit premier flan.In another embodiment, at least one of said second blanks includes a plurality of panels including one is secured to one of the panels of said first blank.

Le premier flan peut être réalisé en matériau à microcannelures ou nanocannelures, en carton compact, en carton ondulé, en polyester ou en polypropylèneThe first blank can be made of material with microcannels or nanocannels, in compact cardboard, in corrugated cardboard, polyester or polypropylene

Au moins un desdits deuxièmes flans peut être réalisé dans un matériau choisi parmi les matériaux à microcannelures ou nanocannelures, le carton, le carton ondulé, le polyester, le polypropylène, la mousse, le métal, le bois, le verre, et les matériaux thermoformés.At least one of said second blanks can be produced in a material chosen from micro-groove materials or nanocannels, cardboard, corrugated cardboard, polyester, polypropylene, foam, metal, wood, glass, and thermoformed materials.

On décrira maintenant à titre d'exemple non limitatif un mode de réalisation particulier de l'invention en référence aux dessins schématiques annexés dans lesquels :

  • la figure 1 est une vue en plan d'un produit d'emballage selon l'invention ;
  • la figure 2 est une vue en coupe selon la ligne II-II de la figure 1 après pliage des moyens de calage ; et
  • la figure 3 est une vue en perspective écorchée de ce produit d'emballage après pliage complet.
A particular embodiment of the invention will now be described by way of nonlimiting example with reference to the appended schematic drawings in which:
  • Figure 1 is a plan view of a packaging product according to the invention;
  • Figure 2 is a sectional view along line II-II of Figure 1 after folding the wedging means; and
  • Figure 3 is a cutaway perspective view of this packaging product after complete folding.

Le produit d'emballage de la figure 1 est composé d'un premier flan 1 destiné à former l'étui et de deux flans 2, 3 destinés à former les moyens de calage. Le flan 1 est ici réalisé en carton compact, tandis que l'un au moins des flans 2 et 3 peut être réalisé en carton ondulé.The packaging product of Figure 1 is composed of a first blank 1 intended to form the case and two blanks 2, 3 intended to form the wedging means. Blank 1 is here made of compact cardboard, while at least one of the blanks 2 and 3 can be made of corrugated cardboard.

Le flan 1 est composé d'une patte de fermeture de fond 5, d'une patte de fermeture de dessus 6 et de panneaux latéraux comportant un panneau avant 7, un panneau arrière 8 et deux panneaux de côtés 9, 10.The blank 1 is composed of a bottom closing tab 5, a top closure tab 6 and side panels comprising a front panel 7, a rear panel 8 and two side panels 9, 10.

Les panneaux latéraux 8-10 sont alignés selon une direction généralement longitudinale, les panneaux 8, 9 étant séparés par une ligne de pliage 11. Les panneaux 9 et 7 sont séparés par une ligne de pliage 12, et les panneaux 7 et 10 sont séparés par une ligne de pliage 13.Side panels 8-10 are aligned in one direction generally longitudinal, the panels 8, 9 being separated by a fold line 11. The panels 9 and 7 are separated by a fold line 12, and the panels 7 and 10 are separated by a fold line 13.

La patte de fermeture 5 s'étend transversalement à partir du panneau 7 dont elle est séparée par une ligne de pliage 14. La patte de fermeture 6 s'étend transversalement à partir du panneau 8 du côté opposé à la patte de fermeture 5 en étant séparée du panneau 8 par une ligne de pliage 15. The closing tab 5 extends transversely from the panel 7 from which it is separated by a fold line 14. The closing tab 6 extends transversely from the panel 8 on the side opposite to the closing tab 5 while being separated from the panel 8 by a fold line 15.

En variante, la patte de fermeture 6 pourrait s'étendre à partir du panneau 7 à l'opposé de la patte 5 (pattes opposées et non pas alternées).Alternatively, the closure tab 6 could extend from panel 7 opposite leg 5 (opposite legs and not not alternate).

Une patte de collage 16 s'étend à partir du panneau 8 à l'opposé du panneau 9 pour être collée à l'extrémité libre du panneau 10 lorsque les panneaux 8-10 sont repliés perpendiculairement les uns aux autres autour des lignes 11-13 pour former la paroi latérale de l'étui.A bonding tab 16 extends from the panel 8 to the opposite of panel 9 to be glued to the free end of the panel 10 when panels 8-10 are folded perpendicular to each other around lines 11-13 to form the side wall of the case.

Deux pattes latérales 17, 18 s'étendent transversalement à partir du panneau 9 dont elles sont séparées par des lignes de pliage respectivement 19, 20.Two lateral tabs 17, 18 extend transversely to from panel 9, separated by lines folding respectively 19, 20.

De même, deux pattes latérales 21 et 22 s'étendent transversalement à partir du panneau 10 dont elles sont séparées par des lignes de pliage respectivement 23, 23'. Les pattes 17 et 21 s'étendent du même côté que la patte de fermeture 6 et les pattes 18 et 22 s'étendent du même côté que la patte de fermeture 5.Similarly, two lateral legs 21 and 22 extend transversely from the panel 10 of which they are separated by fold lines 23, 23 'respectively. The legs 17 and 21 extend on the same side as the leg of closure 6 and tabs 18 and 22 extend on the same side than the closing tab 5.

Une patte rentrante 24 s'étend transversalement à partir du bord libre de la patte de fermeture 6 et un patte rentrante 24' s'étend transversalement à partir du bord libre de la patte de fermeture 5.A re-entrant tab 24 extends transversely from the free edge of the closing tab 6 and a re-entering tab 24 ' extends transversely from the free edge of the tab closing 5.

Lorsque la paroi latérale de l'étui est formée comme cela a été exposé ci-dessus, les pattes 18, 22 et la patte de fermeture 5 peuvent être rabattues perpendiculairement à ces parois latérales pour former le fond de l'étui et, de même, les pattes 17, 21 ainsi que la patte de fermeture 6 peuvent être rabattues perpendiculairement à la paroi latérale pour former le couvercle de l'étui. When the side wall of the case is formed like this has been exposed above, the legs 18, 22 and the leg of closure 5 can be folded perpendicular to these side walls to form the bottom of the case and, similarly, the tabs 17, 21 as well as the closing tab 6 can be folded perpendicular to the side wall to form the cover of the case.

En variante, il est possible de prévoir un fond automatique ou semi-automatique, ou une absence totale de fond et de couvercle de manière à former un simple fourreau.Alternatively, it is possible to provide an automatic background or semi-automatic, or a complete absence of background and cover so as to form a simple sheath.

Les pattes 5 et 6 et les panneaux 7-10 étant ici carrés, l'étui a une forme finale cubique.The legs 5 and 6 and the panels 7-10 being here square, the case has a final cubic shape.

Le flan 2 est formé de quatre panneaux rectangulaires 25-28 s'étendant côte à côte dans la direction longitudinale. Les panneaux 25, 26 sont séparés par une ligne de pliage 29, les panneaux 26, 27 sont séparés par une ligne de pliage 30 et les panneaux 27, 28 sont séparés par une ligne de pliage 31.The blank 2 is formed by four rectangular panels 25-28 extending side by side in the longitudinal direction. The panels 25, 26 are separated by a fold line 29, the panels 26, 27 are separated by a fold line 30 and the panels 27, 28 are separated by a fold line 31.

Le panneau 25 est collé au panneau 7 par l'intermédiaire d'un film de colle approprié 32. Le panneau 25 est décalé par rapport au plan médian de la surface latérale de l'étui en direction de la patte de fermeture 6. Ainsi, après repliement des panneaux 25-28 du flan 2 à 90° les uns des autres, ce flan 2 forme un renfort de la partie supérieure de la paroi latérale de l'étui.The panel 25 is glued to the panel 7 by means of a suitable adhesive film 32. The panel 25 is offset by relative to the median plane of the lateral surface of the case in direction of the closing tab 6. Thus, after folding back panels 25-28 of the blank 2 at 90 ° from each other, this blank 2 forms a reinforcement of the upper part of the wall side of the case.

Le flan 3 est constitué par un panneau unique, ici sensiblement carré et de dimension légèrement inférieure à la patte de fermeture 6. Ce flan 3 est collé à la patte de fermeture 6 par l'intermédiaire d'un film de colle 33.The blank 3 is constituted by a single panel, here substantially square and slightly smaller in dimension than the closing tab 6. This blank 3 is glued to the tab of closure 6 by means of an adhesive film 33.

Le flan 3 sert de renfort à la patte de fermeture 6, par exemple pour la protéger d'une pointe que formerait l'objet contenu dans l'emballage.The blank 3 serves as reinforcement for the closing tab 6, by example to protect it from a point that the object would form contained in the package.

L'invention permet donc une grande souplesse d'utilisation puisqu'elle permet de n'ajouter de la matière qu'aux emplacements où elle est nécessaire. Ainsi dans le cas où l'on souhaiterait renforcer la paroi latérale de l'étui uniquement dans ses parties inférieures et supérieures, le flan 2 pourrait être remplacé par deux flans distincts collés sur le flan 7 respectivement à proximité de son bord situé du côté de la patte de fermeture 6 et à proximité de son bord situé du côté de la patte de fermeture 5.The invention therefore allows great flexibility of use since it allows adding material only to locations where it is needed. So in case we would like to reinforce the side wall of the case only in its lower and upper parts, the blank 2 could be replaced by two separate blanks glued on the blank 7 respectively near its edge located on the side of closure tab 6 and close to its edge located on the side of the closing tab 5.

Les différents éléments du produit décrit ci-dessus étant en carton, leur solidarisation a été présentée comme étant réalisée par collage. Pour des éléments en matière plastique, la solidarisation aurait pu être réalisée par soudage.The different elements of the product described above being in cardboard, their joining was presented as made by collage. For plastic elements, the joining could have been carried out by welding.

Dans tous les cas, le produit d'emballage selon l'invention se présente sous la forme d'une pièce unique aisée à manipuler et pouvant être pliée en une seule opération, éventuellement en plusieurs temps, sur une même chaíne de conditionnement.In all cases, the packaging product according to the invention is present in the form of a single piece easy to handle and can be folded in a single operation, possibly in several stages, on the same packaging chain.
