Description

La présente invention concerne le domaine des emballages, en particulier des emballages tubulaires en matériaux composites, et a pour objet un procédé de fabrication et de mise en place simultanée d'un fond ou d'un couvercle sur le corps d'un emballage tubulaire en matériaux composites.The present invention relates to the field of packaging, in particular tubular packaging made of composite materials, and relates to a method of manufacturing and simultaneously placing a bottom or a cover on the body of a tubular packaging made of composite materials.

Les emballages existants du type boîtes, conteneurs, barils, fûts, sont tous composés d'un corps tubulaire, de section ronde, polygonale, ou toutes autres sections, d'un couvercle et d'un fond. La structure du corps tubulaire, réalisé par enroulement spiralé, droit, convolute ou autres, est en général la suivante :

  • un complexe interne, compatible avec le produit à conditionner. Ce complexe peut comporter deux couches ou plus. Très souvent, la couche présentant les propriétés barrières assurant une étanchéité parfaite est composée d'un film d'aluminium. Elle peut également être en tout autre film présentant les mêmes propriétés barrières et la même faible résistance physique que l'aluminium. Cette couche est d'une épaisseur aussi faible que possible, afin de réduire au maximum le coût de l'emballage à réaliser. Habituellement, une étanchéité optimale est obtenue avec une épaisseur de la couche d'aluminium de l'ordre de 9 à 18 µ. Cette couche d'aluminium est souvent recouverte, de chaque côté, d'une couche d'un matériau différent, par exemple d'un côté de papier et de l'autre d'un film en matière synthétique, ou d'un vernis.
  • une ou plusieurs couches d'un matériau plus rigide que le complexe interne. En général, ces couches sont en carton, c'est-à-dire d'un grammage supérieur à environ 225g/m². Le nombre de couches dépend, bien entendu, de la rigidité souhaitée, un baril de poudre à laver nécessitant une rigidité bien supérieure à un emballage de biscuits, par exemple.
  • une couche ou un complexe externe, imprimé ou non. Il peut s'agir d'une couche simple, par exemple une étiquette imprimée de la dénomination commerciale du produit ou d'autres indications. Il pourra également s'agir d'un complexe garantissant une étanchéité parfaite de l'extérieur vers l'intérieur, afin de protéger les différentes couches de carton d'une quelconque atteinte par un liquide extérieur.
The existing packaging of the box, container, barrel, barrel type is all composed of a tubular body, of round, polygonal section, or any other sections, of a cover and of a bottom. The structure of the tubular body, produced by spiral, straight, convolute or other winding, is generally as follows:
  • an internal complex, compatible with the product to be packaged. This complex can have two or more layers. Very often, the layer having the barrier properties ensuring a perfect seal is composed of an aluminum film. It can also be made of any other film having the same barrier properties and the same low physical resistance as aluminum. This layer is as thin as possible, in order to minimize the cost of the packaging to be produced. Usually, an optimal seal is obtained with a thickness of the aluminum layer of the order of 9 to 18 μ. This layer of aluminum is often covered, on each side, with a layer of a different material, for example on one side of paper and on the other of a film of synthetic material, or of a varnish.
  • one or more layers of a more rigid material than the internal complex. In general, these layers are made of cardboard, that is to say a grammage greater than about 225 g / m². The number of layers depends, of course, on the desired rigidity, a barrel of washing powder requiring a rigidity much higher than a package of cookies, for example.
  • an outer layer or complex, printed or not. It can be a single layer, for example a label printed with the product's trade name or other indications. It could also be a complex guaranteeing a perfect seal from the outside to the inside, in order to protect the different layers of cardboard from any damage by an external liquid.

La liaison de ces différentes couches est assurée par scellage ou collage.The connection of these different layers is ensured by sealing or gluing.

Les fonds ou couvercles de ces emballages sont toujours, actuellement, composés d'une structure totalement différente de celle du corps de l'emballage. En effet, ces fonds ou couvercles doivent être rigides, tout en pouvant être scellés sur le corps tubulaire de l'emballage, de manière à garantir une étanchéité parfaite. Or, le corps étant déjà relativement épais, une très grande énergie calorifique serait nécessaire afin de pouvoir réaliser correctement la soudure d'un couvercle épais ou d'un fond épais sur un corps épais. De plus, afin de pouvoir réaliser la soudure, le couvercle ou le fond doit être plié en forme de U, vers l'intérieur du corps de l'emballage. Or, il est évident que plus l'épaisseur est importante, moins une telle pliure est réalisable.The bottoms or covers of these packages are still, at present, composed of a structure completely different from that of the body of the package. Indeed, these funds or covers must be rigid, while being able to be sealed on the tubular body of the packaging, so as to guarantee a perfect seal. However, the body being already relatively thick, a very high calorific energy would be necessary in order to be able to correctly carry out the welding of a thick cover or of a thick bottom on a thick body. In addition, in order to be able to carry out the welding, the cover or the bottom must be folded in the shape of a U, towards the inside of the body of the packaging. However, it is obvious that the greater the thickness, the less such a folding is achievable.

Actuellement, on réalise, par conséquent, les fonds et les couvercles séparément des corps des emballages, soit en une pièce métallique sertie, soit en matière synthétique, soit sous forme d'une membrane assurant l'étanchéité, par exemple, en aluminium, d'une épaisseur comprise entre 50 µ et 70 µ. Puis, une fois terminés, on les rapporte sur le corps de l'emballage et on les surmonte éventuellement d'une cape ou d'un bouchon protecteur en matière synthétique.Currently, therefore, the bottoms and the covers are produced separately from the bodies of the packages, either in a crimped metal part, or in synthetic material, or in the form of a membrane ensuring the sealing, for example, of aluminum, d '' a thickness between 50 µ and 70 µ. Then, once completed, they are attached to the body of the package and they are possibly surmounted by a cap or protective cap made of synthetic material.

Mais il est clair que tous ces types de fonds et de couvercles présentent l'inconvénient majeur d'augmenter très sensiblement le prix de revient global d'un tel emballage. Il est donc actuellement impossible d'obtenir un emballage tubulaire dont le fond et le couvercle sont fixés de manière parfaitement étanche et qui présentent un faible prix de revient.However, it is clear that all these types of bottoms and covers have the major drawback of very significantly increasing the overall cost price of such packaging. It is therefore currently impossible to obtain a tubular packaging whose bottom and cover are fixed in a perfectly sealed manner and which have a low cost price.

On connaît également du document US-A-2 438 430 un procédé de fabrication et de mise en place simultanée d'un fond ou d'un couvercle sur le corps d'un emballage tubulaire en matériaux composites. Selon le procédé décrit dans ce document, la mise en place du fond ou du couvercle s'effectue à l'aide d'un disque d'un diamètre supérieur au diamètre interne du corps ainsi que d'une membrane dont la matière est identique à celle de la couche interne du corps, à savoir en papier. Mais ce procédé ne permet pas l'obtention d'une bonne étanchéité. En effet, dans ce procédé où il est fait appel au collage, il est prévu que les extrémités du corps s'imprègnent de colle, puisque celle-ci doit s'infiltrer dans celui-ci par capillarité pour l'humidifier. Ainsi, la couche interne en papier permet cette infiltration. De ce fait, ce procédé par collage ne garantit aucunement l'étanchéité du corps de boîte.Document US-A-2 438 430 also discloses a method of manufacturing and simultaneously placing a base or a cover on the body of a tubular packaging made of composite materials. According to the process described in this document, the establishment of the bottom or the cover is carried out using a disc with a diameter greater than the internal diameter of the body as well as a membrane whose material is identical to that of the inner layer of the body, namely paper. However, this process does not make it possible to obtain a good seal. In fact, in this process, where bonding is used, it is intended that the ends of the body become impregnated with adhesive, since the latter must infiltrate therein by capillary action in order to moisten it. Thus, the internal paper layer allows this infiltration. Therefore, this bonding process does not guarantee the tightness of the box body.

La présente invention a pour but de pallier ces inconvénients, et se propose de réaliser un emballage dont le fond et le couvercle sont d'un prix de revient proportionnellement équivalent à celui du corps de l'emballage, tout en garantissant une rigidité et une résistance identiques, quels que soient le format et la section de l'emballage, une étanchéité aux liquides et aux gaz parfaite, une inviolabilité totale, et tout en améliorant encore la présentation extérieure dudit emballage.The present invention aims to overcome these drawbacks, and proposes to provide a package whose bottom and cover are of a cost price proportionally equivalent to that of the body of the package, while ensuring rigidity and resistance identical, whatever the format and the section of the packaging, perfect liquid and gas tightness, total inviolability, and while still improving the external presentation of said packaging.

L'invention a, en effet, pour objet, un procédé de fabrication et de mise en place simultanée d'un fond ou d'un couvercle sur le corps d'un emballage tubulaire en matériaux composites comprenant un complexe interne étanche, compatible avec le produit à conditionner, une ou plusieurs couches d'un matériau plus rigide que le complexe interne et, éventuellement, une couche ou un complexe externe, imprimé ou non, consistant à appliquer sur le corps, à proximité immédiate de l'une de ses deux extrémités, un complexe, identique à celui interne au corps de l'emballage et en contact avec le produit à conditionner, dont la section est en forme de U et détermine avec l'extrémité du corps une cavité, (voir US-A-2 438 430 par exemple), procédé caractérisé en ce que le complexe est appliqué, de manière totalement étanche, par scellage, collage ou autre, préalablement à une mise en place sur le complexe, à l'intérieur de cette cavité, de plusieurs feuilles, qui sont elles-mêmes maintenues en place par collage, la feuille inférieure étant directement collée sur le complexe, puis les feuilles suivantes étant collées successivement les unes sur les autres, les feuilles étant en un matériau plus rigide que le complexe et le nombre de feuilles à appliquer étant fonction de la rigidité du fond ou du couvercle de l'emballage à obtenir.The subject of the invention is, in fact, a method of manufacturing and placing simultaneously a bottom or a cover on the body of a tubular packaging made of composite materials comprising a sealed internal complex, compatible with the product to be packaged, one or more layers of a material more rigid than the internal complex and, optionally, an external layer or complex, printed or not, consisting of applying to the body, in the immediate vicinity of one of its two ends, a complex, identical to that internal to the body of the package and in contact with the product to be packaged, the section of which is U-shaped and determines with the end of the body a cavity, (see US-A-2 438 430 for example), process characterized in that the complex is applied, in a completely sealed manner, by sealing, gluing or other, prior to placing on the complex, inside this cavity, several sheets, which are themselves maintained in place by gluing, the lower sheet being directly glued to the complex, then the following sheets being successively glued to each other, the sheets being made of a more rigid material than the complex and the number of sheets to be applied depending on the stiffness of the bottom or lid of the packaging to be obtained.

Conformément à l'invention, le procédé de fabrication et de mise en place simultanée d'un fond ou d'un couvercle sur le corps 1 d'un emballage tubulaire en matériaux composites comprenant un complexe interne 2 étanche, compatible avec le produit à conditionner, une ou plusieurs couches 3 d'un matériau plus rigide que le complexe 2 et, éventuellement, une couche ou un complexe externe 4, imprimé ou non, consistant à appliquer sur le corps 1, à proximité immédiate de l'une 1′ de ses deux extrémités, un complexe 7, identique à celui 2 interne au corps 1 de l'emballage et en contact avec le produit à conditionner, dont la section est en forme de U et détermine avec l'extrémité 1′ du corps 1 une cavité 15, consiste à appliquer le complexe 7 de manière totalement étanche par scellage, collage ou autre, préalablement à une mise en place sur le complexe 7, à l'intérieur de cette cavité 15, de plusieurs feuilles 8, qui sont elles-mêmes maintenues en place par collage, la feuille inférieure 8A étant directement collée sur le complexe 7, puis les feuilles suivantes 8B, ... 8Z étant collées successivement les unes sur les autres, les feuilles 8 étant en un matériau plus rigide que le complexe 7 et le nombre de feuilles 8 à appliquer étant fonction de la rigidité du fond ou du couvercle de l'emballage à obtenir.According to the invention, the method of manufacturing and placing simultaneously a bottom or a cover on the body 1 of a tubular packaging made of composite materials comprising an internal complex 2 sealed, compatible with the product to be packaged , one or more layers 3 of a more rigid material than the complex 2 and, optionally, an outer layer or complex 4, whether or not printed, consisting of applying to the body 1, in the immediate vicinity of one 1 ′ of its two ends, a complex 7, identical to that 2 internal to the body 1 of the packaging and contact with the product to be packaged, the cross section of which is U-shaped and determines with the end 1 ′ of the body 1 a cavity 15, consists in applying the complex 7 in a completely sealed manner by sealing, bonding or the like, prior to a placement on the complex 7, inside this cavity 15, of several sheets 8, which are themselves held in place by bonding, the lower sheet 8A being directly bonded to the complex 7, then the following sheets 8B , ... 8Z being bonded successively to each other, the sheets 8 being made of a more rigid material than the complex 7 and the number of sheets 8 to be applied being a function of the rigidity of the bottom or of the cover of the package to be get.

Les feuilles 8 sont maintenues en place par collage, la feuille inférieure 8A étant directement collée sur le complexe 7 et les éventuelles feuilles suivantes 8B ... et 8Z étant collées les unes sur les autres, les feuilles 8 pouvant être en papier ondulé, en carton, en bois, en métal, en matière synthétique, en polystyrène expansé ou toutes autres matières.The sheets 8 are held in place by bonding, the bottom sheet 8A being directly bonded to the complex 7 and any subsequent sheets 8B ... and 8Z being bonded to each other, the sheets 8 may be made of corrugated paper, in cardboard, wood, metal, synthetic material, expanded polystyrene or any other material.

Selon la première variante de l'invention, le complexe 7 est replié sur la surface externe de l'extrémité tubulaire 1′ du corps 1 de l'emballage, juste avant son application par scellage, collage ou autre (figures 1B et 2B).According to the first variant of the invention, the complex 7 is folded over the external surface of the tubular end 1 ′ of the body 1 of the packaging, just before its application by sealing, gluing or the like (FIGS. 1B and 2B).

Selon la seconde variante de l'invention, l'extrémité tubulaire 1′ du corps 1 de l'emballage pourvu du complexe 7 est évasée, de manière à renforcer la rigidité totale de l'emballage (figure 3E).According to the second variant of the invention, the tubular end 1 ′ of the body 1 of the package provided with the complex 7 is flared, so as to reinforce the total rigidity of the package (FIG. 3E).

Comme on peut le voir sur la figure 3, il sera possible d'appliquer, en outre, une couche ou un complexe externe 9 qui peut être identique à celui 4 externe au corps 1 de l'emballage sur la feuille supérieure 8A, ...ou 8Z et éventuellement sur la tranche de l'extrémité tubulaire 1′ recouverte ou non du complexe 7 (figure 3F).As can be seen in Figure 3, it will be possible to apply, in addition, a layer or a complex external 9 which can be identical to that 4 external to the body 1 of the packaging on the upper sheet 8A, ... or 8Z and possibly on the edge of the tubular end 1 ′ covered or not with the complex 7 (FIG. 3F) .

Selon la troisième variante de l'invention, l'extrémité tubulaire 1′ du corps 1 de l'emballage est rembordée autour du complexe 7 et éventuellement de la feuille supérieure 8A, ... ou 8Z, en forme de U, de manière à renforcer la rigidité totale de l'emballage (figures 4F et 5E).According to the third variant of the invention, the tubular end 1 ′ of the body 1 of the packaging is wrapped around the complex 7 and possibly of the upper sheet 8A, ... or 8Z, in the shape of a U, so as to reinforce the total rigidity of the packaging (Figures 4F and 5E).

Comme on peut le voir sur la figure 4, on pourra également appliquer, en outre, une couche ou un complexe externe 9 imprimé ou non, qui peut être identique à celui 4 externe au corps 1 de l'emballage, sur la feuille supérieure 8A, ... ou 8Z, le cas échéant juste avant l'opération de rembordement (figure 4E).As can be seen in FIG. 4, it is also possible to apply, in addition, a layer or an external complex 9 printed or not, which may be identical to that 4 external to the body 1 of the package, on the upper sheet 8A , ... or 8Z, if necessary just before the wrapping operation (Figure 4E).

Le procédé de fabrication et de mise en place d'un fond ou d'un couvercle sur le corps 1 d'un emballage ne consiste donc plus, comme dans l'art antérieur, d'une part, à réaliser séparément le fond ou le couvercle, puis, d'autre part, à le rapporter et à le fixer sur le corps 1 par scellage, collage, agrafage ou autre, mais à fabriquer le fond ou le couvercle simultanément à sa mise en place sur le corps 1.The method of manufacturing and placing a bottom or a cover on the body 1 of a package therefore no longer consists, as in the prior art, on the one hand, of producing the bottom or the cover, then, on the other hand, to attach it and fix it to the body 1 by sealing, gluing, stapling or the like, but to manufacture the base or the cover simultaneously with its positioning on the body 1.

Le déroulement du procédé consiste donc à réaliser les opérations suivantes :

  • scellage du complexe 7 à proximité immédiate de l'une 1′ de ses deux extrémités soit sur la paroi interne du corps 1 (figures 3B, 4B et 5B), soit sur la paroi externe (figures 1B et 2B) si le complexe 7 est préalablement replié avant scellage ou collage, ce qui, vu sa très faible épaisseur, ne présente aucune difficulté. Dans tous les cas, le complexe 7 est disposé de telle sorte que sa section soit en forme de U tourné vers l'intérieur du corps 1 de l'emballage, de façon à présenter une cavité 15 délimitée par le complexe 7 lui-même et l'extrémité tubulaire 1′ du corps 1. Ce complexe 7 sera avantageusement identique à celui 2 du corps de l'emballage et pourra être constitué, par exemple, par trois couches, la couche interne étant en un papier de 40 à 60 g/m², la couche intermédiaire en aluminium de 9 à 18 µ d'épaisseur et la couche externe en un vernis ou un film synthétique de 3 à 30 g/m² (par exemple un film de polyéthylène).
    L'utilisation d'un tel complexe 7 pour le fond ou le couvercle permet donc de réaliser des économies substantielles sur le prix de revient d'un tel emballage, la couche d'aluminium présentant les propriétés barrières indispensables à une étanchéité parfaite, ne présentant plus qu'une épaisseur de 9 à 18 µ, au lieu de 50 ou 60 µ. Bien entendu, le scellage d'un tel complexe 7 sur le corps 1 de l'emballage s'effectue en ne consommant qu'un minimum de calories.
  • mise en place d'une ou plusieurs feuilles 8 à l'intérieur de la cavité 15 sur le complexe 7 (figures 1C et 1D, 2C et 2D, 3C et 3D, 4C et 4D, 5C et 5D). Les feuilles 8 seront maintenues en place soit par collage (figures 2D et 3D), soit par rembordement ultérieur (figures 4F et 5E), soit par collage d'une couche ou d'un complexe externe 9 (figures 1E et 3F) etc..., selon la rigidité de l'emballage souhaitée.
The process therefore consists of carrying out the following operations:
  • sealing of the complex 7 in the immediate vicinity of one 1 ′ of its two ends either on the internal wall of the body 1 (FIGS. 3B, 4B and 5B), or on the external wall (FIGS. 1B and 2B) if the complex 7 is previously folded before sealing or gluing, which, given its very small thickness, presents no difficulty. In all cases, the complex 7 is arranged so that its section is U-shaped facing the inside of the body 1 of the package, so as to present a cavity 15 delimited by the complex 7 itself and the tubular end 1 ′ of the body 1. This complex 7 will advantageously be identical to that 2 of the body of the packaging and may be constituted, for example, by three layers, the internal layer being made of paper of 40 to 60 g / m², the intermediate layer of aluminum 9 to 18 µ thick and the outer layer in a varnish or a synthetic film of 3 to 30 g / m² (for example a polyethylene film).
    The use of such a complex 7 for the bottom or the lid therefore makes it possible to make substantial savings on the cost price of such packaging, the aluminum layer having the barrier properties essential for perfect sealing, not having more than a thickness of 9 to 18 µ, instead of 50 or 60 µ. Of course, the sealing of such a complex 7 on the body 1 of the packaging is carried out while consuming only a minimum of calories.
  • placing one or more sheets 8 inside the cavity 15 on the complex 7 (FIGS. 1C and 1D, 2C and 2D, 3C and 3D, 4C and 4D, 5C and 5D). The sheets 8 will be held in place either by bonding (Figures 2D and 3D), or by subsequent overlapping (Figures 4F and 5E), or by bonding a layer or an external complex 9 (Figures 1E and 3F) etc. .., depending on the stiffness of the desired packaging.

En général, les feuilles 8 seront collées. Avant la disposition de la feuille 8A sur le complexe 7, on enduit soit la surface de contact du complexe 7 avec la feuille 8, soit la surface de contact de la feuille 8 avec le complexe 7, soit les deux surfaces, partiellement ou totalement d'une couche de colle 14. Puis, si des feuilles supplémentaires 8B ... et 8Z sont à appliquer, on enduit soit la surface de contact de la première feuille 8A, en place, avec la seconde 8B, soit la surface de contact de la seconde feuille 8B avec la première 8A, soit les deux surfaces, partiellement ou totalement d'une couche de colle 14, et ainsi de suite jusqu'à la feuille 8Z. La colle employée pourra être par exemple de l'acétate de polyvinyle.In general, sheets 8 will be glued. Before the arrangement of the sheet 8A on the complex 7, either the contact surface of the complex 7 with the sheet 8 is coated, or the contact surface of the sheet 8 with the complex 7, or the two surfaces, partially or totally d 'a layer of glue 14. Then, if additional sheets 8B ... and 8Z are to be applied, either the contact surface of the first sheet 8A is coated, in place, with the second 8B, or the contact surface of the second sheet 8B with the first 8A, or the two surfaces, partially or totally with a layer of adhesive 14, and so on up to the sheet 8Z. The adhesive used may for example be polyvinyl acetate.

Le type de matériau à utiliser pour les feuilles 8 dépend, bien entendu, du produit à conditionner. Le bois permet une excellente isolation aux variations de température, le métal permet un transfert de chaleur, etc ... Si des feuilles 8 en carton sont utilisées, le grammage sera normalement supérieur à 225 g/m². L'épaisseur de chaque feuille 8 sera variable en fonction du poids et de la quantité du produit à conditionner. Elle pourra varier entre 0,3 mm et 1 mm.The type of material to be used for the sheets 8 depends, of course, on the product to be packaged. Wood allows excellent insulation to temperature variations, metal allows heat transfer, etc. If 8 sheets of cardboard are used, the grammage will normally be greater than 225 g / m². The thickness of each sheet 8 will vary depending on the weight and quantity of the product to be packaged. It can vary between 0.3 mm and 1 mm.

La feuille supérieure 8A ... ou 8Z pourra être rectiligne comme les autres feuilles 8 (figures 1D, 3D et 4D), ou en forme de U (figures 2D et 5D), comme le complexe 7, ce afin d'accroître davantage la rigidité du couvercle ou du fond.The upper sheet 8A ... or 8Z can be rectilinear like the other sheets 8 (Figures 1D, 3D and 4D), or U-shaped (Figures 2D and 5D), like the complex 7, in order to further increase the stiffness of the cover or bottom.

Le nombre de feuilles 8 dépend de la rigidité souhaitée. Il est donc possible, grâce à l'invention, de moduler la structure même du fond ou du couvercle simultanément à sa mise en place, en fonction du produit à emballer, de son poids, des dimensions de l'emballage, de sa section, etc ...

  • mise en place de la couche ou du complexe externe 9 (figures 1E, 3F et 4E). Il s'agit, le plus souvent, d'une étiquette qui sera collée sur la feuille supérieure 8A, ... ou 8Z. Si l'extrémité tubulaire 1′ du corps 1 est rembordée par la suite (figure 4F), cette mise en place de l'étiquette doit avoir lieu avant le rembordement (figure 4E). Par contre, si l'extrémité tubulaire 1′ du corps 1 est évasée (figure 3E), elle aura lieu après l'évasage (figure 3F). L'utilisation d'une étiquette sous forme de complexe permet d'obtenir une étanchéité également de l'extérieur vers l'intérieur et empêche, par exemple, qu'un liquide extérieur ne vienne mouiller les feuilles 8.
  • mise en place éventuelle d'une cape 5 (figure 6) ou d'un bouchon 6 (figure 7) amovible, afin de protéger le couvercle ou le fond dans des cas bien spécifiques, et surtout afin de permettre le rebouchage de l'emballage après ouverture. La cape 5 ou le bouchon 6 pourront être, par exemple, en matière synthétique.
The number of sheets 8 depends on the desired rigidity. It is therefore possible, thanks to the invention, to modulate the very structure of the bottom or of the cover simultaneously with its installation, depending on the product to be packaged, its weight, the dimensions of the package, its section, etc ...
  • placement of the layer or of the external complex 9 (FIGS. 1E, 3F and 4E). This is most often a label which will be stuck on the top sheet 8A, ... or 8Z. If the tubular end 1 ′ of the body 1 is subsequently folded up (FIG. 4F), this positioning of the label must take place before the rebounding (FIG. 4E). On the other hand, if the tubular end 1 ′ of the body 1 is flared (FIG. 3E), it will take place after the flaring (FIG. 3F). The use of a label in the form of a complex makes it possible to obtain a seal also from the outside to the inside and prevents, for example, that an external liquid comes to wet the sheets 8.
  • possible installation of a cap 5 (FIG. 6) or of a removable cap 6 (FIG. 7), in order to protect the cover or the bottom in very specific cases, and above all in order to allow the packaging of the packaging after opening. The cap 5 or the plug 6 may, for example, be made of synthetic material.

Conformément à une autre caractéristique préférée de l'invention, le complexe 7 est pourvu d'une fragilisation 11 de l'une de ses couches, de manière à faciliter l'arrachage du couvercle du corps 1 de l'emballage, une languette d'arrachage 10 étant éventuellement collée ou soudée sur la feuille supérieure 8A, ... ou 8Z avant ou après la mise en place de cette dernière, un léger jeu 13 étant prévu entre les feuilles 8 et la surface interne du corps 1 (figures 6 et 7). La fragilisation 11 permet de faciliter une ouverture totale du couvercle. La languette 10 étant disposée sur la feuille supérieure 8A, ... ou 8Z, il est, bien entendu, indispensable que, selon cette forme d'exécution, les feuilles 8 soient collées les unes sur les autres, la feuille 8A étant collée elle aussi sur le complexe 7. La fragilisation Il sera avantageusement située sur le bord vertical 7' du complexe 7 et sur toute sa circonférence. Le jeu 13 prévu entre toutes les feuilles 8 et la surface interne du corps 1 permet un meilleur arrachage du couvercle.In accordance with another preferred characteristic of the invention, the complex 7 is provided with a weakening 11 of one of its layers, so as to facilitate the tearing off of the cover of the body 1 of the packaging, a tongue of tear-off 10 possibly being glued or welded to the upper sheet 8A, ... or 8Z before or after placement of the latter, a slight clearance 13 being provided between the sheets 8 and the internal surface of the body 1 (Figures 6 and 7). The weakening 11 makes it possible to facilitate full opening of the cover. The tongue 10 being arranged on the upper sheet 8A, ... or 8Z, it is, of course, essential that, according to this embodiment, the sheets 8 are glued to each other, the sheet 8A being glued also on the complex 7. The embrittlement It will advantageously be located on the vertical edge 7 'of the complex 7 and over its entire circumference. The clearance 13 provided between all of the sheets 8 and the internal surface of the body 1 allows better removal of the cover.

Selon une variante de réalisation du dispositif d'ouverture, les feuilles 8A, ... et 8Z sont pourvues chacune d'une ouverture 12 et sont disposées de telle sorte que ces ouvertures 12 se superposent, autorisant ainsi un accès direct au complexe 7 de façon à pouvoir le percer, une languette d'arrachage 10 étant éventuellement collée ou soudée sur le complexe 7 avant ou après mise en place de ce dernier (figures 8 et 9). Ainsi, une ouverture partielle du couvercle est possible.According to an alternative embodiment of the opening device, the sheets 8A, ... and 8Z are each provided with an opening 12 and are arranged so that these openings 12 are superimposed, thus allowing direct access to the complex 7 of so as to be able to pierce it, a tear-off tab 10 possibly being glued or welded to the complex 7 before or after installation of the latter (FIGS. 8 and 9). Thus, partial opening of the cover is possible.

L'emballage obtenu par application du procédé, consiste en un corps 1 de forme tubulaire comprenant un complexe interne 2 étanche, compatible avec le produit à conditionner, une ou plusieurs couches 3 d'un matériau plus rigide que le complexe 2 et, éventuellement, une couche ou un complexe externe 4 imprimé ou non, l'emballage comportant un fond et/ou un couvercle constitué, de l'intérieur de l'emballage vers l'extérieur, par un complexe 7 identique à celui interne au corps 1 et en contact avec le produit à conditionner, par une ou plusieurs feuilles 8 en un matériau plus rigide que le complexe 7, tel que du papier ondulé, du carton, du bois, du métal, une matière synthétique, du polystyrène expansé ou toutes autres matières, le nombre de feuilles 8 à appliquer étant fonction de la rigidité du fond ou du couvercle de l'emballage à obtenir, et éventuellement par une couche ou un complexe externe 9 imprimé ou non.The packaging obtained by application of the process consists of a body 1 of tubular shape comprising a sealed internal complex 2, compatible with the product to be packaged, one or more layers 3 of a more rigid material than the complex 2 and, optionally, a layer or an external complex 4 printed or not, the packaging comprising a bottom and / or a cover formed, from the inside of the packaging to the outside, by a complex 7 identical to that internal to the body 1 and in contact with the product to be packaged, using one or more sheets 8 of a more rigid material than the complex 7, such as corrugated paper, cardboard, wood, metal, a synthetic material, expanded polystyrene or any other material, the number of sheets 8 to be applied being a function of the rigidity of the bottom or of the cover of the packaging to be obtained, and optionally by a layer or an external complex 9 printed or not.

Selon une caractéristique préférée, le complexe 7 est replié sur l'extrémité tubulaire 1′ du corps 1 de l'emballage, la feuille supérieure 8A, ... ou 8Z étant soit rectiligne (figure 1E), soit en forme de U (figure 2D) de manière à renforcer la rigidité du fond ou du couvercle de l'emballage.According to a preferred characteristic, the complex 7 is folded over the tubular end 1 ′ of the body 1 of the packaging, the upper sheet 8A, ... or 8Z being either rectilinear (FIG. 1E) or in the shape of a U (FIG. 2D) so as to reinforce the rigidity of the bottom or cover of the package.

Selon une autre caratéristique préférée, l'extrémité tubulaire 1′ du corps 1 de l'emballage est soit évasée (figure 3F), ainsi que le complexe 7, soit rembordée autour du complexe 7 (figure 4F) et éventuellement de la feuille supérieure 8A, ... ou 8Z en forme de U (figure 5E).According to another preferred characteristic, the tubular end 1 ′ of the body 1 of the package is either flared (FIG. 3F), as well as the complex 7, or is wrapped around the complex 7 (FIG. 4F) and possibly the top sheet 8A , ... or 8Z in a U shape (figure 5E).

Comme le montrent les figures 10 à 13, les moyens pour la mise en place d'un fond ou d'un couvercle sur le corps 1 d'un emballage de forme tubulaire en matériau composite consistent en un dispositif 16 pour la mise en place du fond de l'emballage et un dispositif 16 identique pour la mise en place du couvercle de l'emballage, le remplissage de l'emballage par le produit à emballer s'effectuant sur un poste de travail situé entre ces deux dispositifs 16, chaque dispositif 16 étant soit du type carrousel (figures 10 et 11), soit du type postes en ligne (figures 12 et 13), à axe vertical ou horizontal, le corps 1 de l'emballage pouvant être également disposé verticalement ou horizontalement.As shown in Figures 10 to 13, the means for the establishment of a bottom or a cover on the body 1 of a tubular packaging of composite material consist of a device 16 for the establishment of the bottom of the packaging and an identical device 16 for fitting the packaging lid, the filling of the packaging with the product to be packaged being carried out at a work station located between these two devices 16, each device 16 being either of the carousel type (FIGS. 10 and 11), or of the line station type (FIGS. 12 and 13), with a vertical or horizontal axis, the body 1 of the packaging can also be arranged vertically or horizontally.

A titre d'exemple, pour la fabrication et la mise en place du fond d'un emballage tubulaire en forme de boîte cylindrique, identique à celui représenté aux figures 1 et 2 des dessins annexés, un tel dispositif 16 peut être équipé de douze postes de travail, à savoir :

poste A
: introduction du corps 1 ;
poste B
: mise en place du complexe 7 et scellage à chaud ;
poste C
: dépose de la colle ;
poste D
: mise en place et collage de la feuille 8A ;
poste E
: dépose de la colle ;
poste F
: mise en place et collage de la feuille 8B rectiligne ou en forme de U ;
poste G
: dépose de la colle ;
poste H
: mise en place et collage de la couche ou du complexe 9 sous la forme d'une étiquette ;
poste I
: rembordement ou évasage de l'extrémité tubulaire 1′ du corps 1 ;
poste J
: mise en place d'une cape 14 ou d'un bouchon 15 ;
poste K
: poste de contrôle ;
poste L
: évacuation du corps 1 de l'emballage muni du fond.
Puis le remplissage de la boîte s'effectue sur un autre poste, et elle est alors amenée dans un second dispositif 16, permettant la fabrication et la mise en place du couvercle. Si ce dernier doit avoir rigoureusement la même structure que le fond, le second dispositif 16 sera rigoureusement identique au premier.By way of example, for the manufacture and installation of the bottom of a tubular packaging in the form of a cylindrical box, identical to that shown in Figures 1 and 2 of the accompanying drawings, such a device 16 can be equipped with twelve stations of work, namely:
post A
: introduction of the body 1;
post B
: installation of complex 7 and heat sealing;
post C
: removing the glue;
post D
: establishment and bonding of sheet 8A;
post E
: removing the glue;
post F
: establishment and bonding of the sheet 8B straight or U-shaped;
post G
: removing the glue;
post H
: establishment and bonding of the layer or complex 9 in the form of a label;
post I
: folding or flaring of the tubular end 1 ′ of the body 1;
post J
: fitting a cap 14 or a plug 15;
post K
: checkpoint ;
post L
: evacuation of body 1 from the packaging provided with the bottom.
Then the filling of the box is carried out on another station, and it is then brought into a second device 16, allowing the manufacture and the establishment of the cover. If the latter must have strictly the same structure as the bottom, the second device 16 will be strictly identical to the first.

Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté aux dessins annexés.Of course, the invention is not limited to the embodiment described and shown in the accompanying drawings.
