Abstract

The method for fitting a base (6) to a tubular container (1) of non-circular section after filling consists of inserting the base with the aid of a male tool (P) and fixing it in position with adhesive film and by folding over and crimping the edge of the container wall. The open end of the container is first fitted between two opposite fixed jaws, the base is positioned between the jaws, and surplus air is expelled from the container by two mobile pressure grippers (S1, S2) before the base is fixed by activating the adhesive film and folding over the edge of the container wall as it is held between the fixed and moving (M3, M4) jaws.

Description

La présente invention concerne un procédé de mise en place du fond d'un emballage comprenant un corps tubulaire de section transversale non ronde de section transversale non ronde fermé par un couvercle et contenant le produit à conditionner, ledit fond ayant la forme d'une cuvette dont les dimensions correspondent à la section transversale du corps tubulaire, la cuvette étant fixée après son introduction, au moyen d'un outil mâle, dans le corps par l'activation d'un adhésif et pliage du bord du corps tubulaire.The present invention relates to a method of placing the bottom of a package comprising a tubular body of non-round cross section of non-round cross section closed by a cover and containing the product to be packaged, said bottom having the shape of a bowl. the dimensions of which correspond to the cross section of the tubular body, the bowl being fixed after its introduction, by means of a male tool, into the body by activating an adhesive and folding the edge of the tubular body.

Dans la demande de brevet EP-A-0 668 151 du déposant on a proposé un procédé de fabrication d'un emballage tubulaire fait de préférence d'une matière recyclable telle que du papier ou du carton dont le couvercle et le fond sont également faits d'un matériau au moins similaire. Après avoir fixé le couvercle et l'éventuelle membrane d'inviolabilité, l'emballage est rempli avec le produit à conditionner et on fixe le fond. Le fond est une cuvette présentant les dimensions et la forme de la section transversale du corps tubulaire et elle est introduite à l'intérieur du corps avec un outil mâle. Néanmoins, lors de l'introduction de cette cuvette qui vient frotter contre le pourtour intérieur du corps tubulaire l'air qui est chassé par le déplacement de ladite cuvette a de la peine à sortir ce qui, soit retarde le procédé de l'introduction et finalement la fixation du fond, soit on crée une surpression à l'intérieur de l'emballage qui n'est pas souhaitée. Au contraire, on désire laisser, après le scellage de l'emballage, subsister une pression négative à l'intérieur de l'emballage. Cette pression négative permet, d'une part, une meilleure conservation du produit emballé et, d'autre part, en cas d'échauffement de l'emballage d'éviter la création d'une surpression à l'intérieur de l'emballage pouvant conduire à la destruction de son étanchéité.In patent application EP-A-0 668 151 by the applicant, a method of manufacturing a tubular packaging has been proposed, preferably made of a recyclable material such as paper or cardboard, the cover and bottom of which are also made. of at least similar material. After fixing the cover and any tamper-evident membrane, the packaging is filled with the product to be conditioned and the bottom is fixed. The bottom is a bowl having the dimensions and the shape of the cross section of the tubular body and it is introduced inside the body with a male tool. However, during the introduction of this bowl, which rubs against the inside periphery of the tubular body, the air which is expelled by the displacement of said bowl has difficulty in escaping, which either delays the process of introduction and finally fixing the bottom, or creating an overpressure inside the packaging which is not desired. On the contrary, it is desired to leave, after the packaging has been sealed, a negative pressure remains inside the packaging. This negative pressure allows, on the one hand, a better conservation of the packaged product and, on the other hand, in case of heating of the packaging to avoid the creation of an overpressure inside the packaging can lead to the destruction of its seal.

On a proposé différentes méthodes pour permettre d'évacuer cet air, notamment d'utiliser une source de pression négative pour l'évacuer et permettre ainsi la mise en place de la cuvette. Cette manière de faire présente des inconvénients, car en fonction de la forme de la section du corps tubulaire, il est parfois difficile d'obtenir une étanchéité parfaite au moment de mise sous pression négative et il en résulte des variations de pression intérieure pouvant nuire à l'étanchéité de l'emballage.Various methods have been proposed to allow this air to be evacuated, in particular to use a source of negative pressure to evacuate it and thus allow the positioning of the bowl. This method has drawbacks, because depending on the shape of the section of the tubular body, it is sometimes difficult to obtain a perfect seal when negative pressure is applied and this results in variations in internal pressure which can adversely affect the tightness of the packaging.

La présente invention a pour but de proposer un procédé permettant de pallier ces inconvénients par des moyens simples.The object of the present invention is to propose a method making it possible to overcome these drawbacks by simple means.

Le procédé selon l'invention est caractérisé en ce que l'on procède selon les étapes suivantes :

  • a) on introduit l'extrémité ouverte du corps tubulaire entre deux mâchoires opposées fixes épousant parfaitement deux parties opposées de l'extrémité du corps tubulaire, et la distance entre les deux mâchoires étant inférieure à la distance entre lesdites parties opposées de sorte que les parties non enserrées dans lesdites mâchoires subissent une déformation non permanente en s'écartant l'une de l'autre;
  • b) on met en place le fond au moyen d'un poinçon, ledit font étant maintenu à sa position définitive par lesdites mâchoires fixes et le poinçon;
  • c) on serre deux régions opposées de la surface latérale du corps tubulaire par deux organes de serrage se trouvant au-dessous de deux mâchoires mobiles destinées à agir sur les portions de l'extrémité libre du corps tubulaire non enserrées par les mâchoires fixes pour chasser au moins partiellement l'air contenu dans le corps tubulaire;
  • d) on serre les mâchoires mobiles pour mettre en contact la totalité du bord intérieur de l'extrémité libre du corps tubulaire avec la cuvette;
  • e) on procède à l'activation du film adhésif et, par la suite à la libération de l'emballage fermé.
The method according to the invention is characterized in that the following steps are carried out:
  • a) the open end of the tubular body is introduced between two fixed opposite jaws perfectly matching two opposite parts of the end of the tubular body, and the distance between the two jaws being less than the distance between said opposite parts so that the parts not enclosed in said jaws undergo a non-permanent deformation by deviating from one another;
  • b) the bottom is put in place by means of a punch, said font being held in its final position by said fixed jaws and the punch;
  • c) two opposite regions of the lateral surface of the tubular body are clamped by two clamping members located below two movable jaws intended to act on the portions of the free end of the tubular body which are not enclosed by the fixed jaws for driving out at least partially the air contained in the tubular body;
  • d) the movable jaws are clamped so as to bring the entire inner edge of the free end of the tubular body into contact with the bowl;
  • e) the adhesive film is activated and, subsequently, the closed packaging is released.

L'avantage de la présente invention réside sur le fait qu'en utilisant des moyens simples pour appliquer des forces opposées sur des surfaces diamétralement opposées de l'emballage, on obtient une déformation du bord de l'emballage suffisante pour permettre l'introduction de la cuvette tout en permettant d'évacuer l'air chassé par cette introduction, entre l'arête de la cuvette et le bord déformé de l'emballage. Il est évident que le procédé est applicable sur un emballage permettant une légère déformation élastique. En plus, on obtient l'évacuation partielle de l'air contenu dans l'emballage en serrant les flancs du corps tubulaire.The advantage of the present invention resides in the fact that by using simple means to apply opposite forces to diametrically opposite surfaces of the packaging, a deformation of the edge of the packaging is obtained which is sufficient to allow the introduction of the bowl while allowing the air expelled by this introduction to be evacuated between the edge of the bowl and the deformed edge of the packaging. It is obvious that the method is applicable on a package allowing a slight elastic deformation. In addition, the partial evacuation of the air contained in the packaging is obtained by tightening the sides of the tubular body.

Il est bien entendu prévu que les déformations auxquelles l'emballage est soumis restent dans le domaine de l'élasticité du matériau pour éviter toute détérioration de l'emballage.It is of course expected that the deformations to which the packaging is subjected remain within the range of the elasticity of the material to avoid any deterioration of the packaging.

Selon une variante d'exécution, si la section de l'emballage est rectangulaire les mâchoires fixes agissent sur les petits côtés de la surface du corps tubulaire.According to an alternative embodiment, if the packaging section is rectangular, the fixed jaws act on the short sides of the surface of the tubular body.

Selon une autre variante d'exécution, la section de l'emballage est elliptique et les mâchoires fixes enserrent les régions situées de part et d'autre des extrémités du grand axe de l'ellipse.According to another alternative embodiment, the section of the packaging is elliptical and the fixed jaws enclose the regions situated on either side of the ends of the major axis of the ellipse.

Selon une autre variante d'exécution, la section a une forme semi-circulaire et les mâchoires fixes enserrent les régions situées aux extrémités de la corde.According to another alternative embodiment, the section has a semi-circular shape and the fixed jaws enclose the regions located at the ends of the rope.

Enfin, selon une autre variante d'exécution et pour pouvoir accélérer le processus de mise en place du fond, on munit la matrice de formage de la cuvette du fond de canaux d'aspiration pour permettre l'évacuation rapide de l'air chassé par la mise en place du fond dans le corps tubulaire.Finally, according to another alternative embodiment and to be able to accelerate the process of setting up the bottom, the forming matrix of the bottom bowl is provided with suction channels to allow rapid evacuation of the air expelled by the establishment of the bottom in the tubular body.

L'invention sera décrite plus en détail à l'aide du dessin annexéThe invention will be described in more detail using the attached drawing

La figure 1 est une vue de haut du corps tubulaire d'un emballage avec les mâchoires.Figure 1 is a top view of the tubular body of a package with the jaws.

La figure 2 est une vue de côté.Figure 2 is a side view.

La figure 3 est une vue de côté d'une variante d'exécution.Figure 3 is a side view of an alternative embodiment.

Un emballage 1 de section sensiblement rectangulaire, dont l'une des extrémités est déjà obturée par un couvercle et éventuellement une membrane d'obturation et contenant déjà le produit à conditionner est introduit entre deux mâchoires M1, M2 fixes présentant des surfaces correspondant à la forme et dimensions de la surface latérale de deux portions 2, 3 opposées de l'emballage 1. Dans le cas présent, le choix est porté sur les deux faces présentant la plus petite surface. Il est nécessaire que les mâchoires M1, M2 épousent lesdites faces, car l'espacement entre les mâchoires est inférieur à l'espacement des faces 2, 3 de l'emballage de sorte à obtenir l'éloignement des deux autres côtés 4, 5 du bord de l'emballage.A packaging 1 of substantially rectangular section, one end of which is already closed by a cover and possibly a sealing membrane and already containing the product to be packaged is introduced between two fixed jaws M1, M2 having surfaces corresponding to the shape and dimensions of the surface lateral of two opposite portions 2, 3 of the packaging 1. In the present case, the choice is made on the two faces having the smallest surface. It is necessary for the jaws M1, M2 to match said faces, because the spacing between the jaws is less than the spacing of the faces 2, 3 of the packaging so as to obtain the distance from the other two sides 4, 5 of the edge of the packaging.

Au moyen d'un poinçon P ayant la forme de la cuvette 6 qui formera le fond, on met en place cette cuvette entre les mâchoires M1 et M2, la cuvette se trouvant ainsi dans sa position définitive. Par la suite au moyen de deux organes de serrage S1 et S2 on applique des forces antagonistes F3 et F4 contre les deux portions opposées de la surface latérale de l'emballage 1 et notamment dans des régions se trouvant sous deux mâchoires mobiles M3 et M4. Ce serrage a pour effet de chasser au moins une partie de l'air se trouvant encore dans le corps tubulaire 1. Par la suite, tout en maintenant les forces de serrage S3, S4 on rapproche deux mâchoires M3 et M4 en appliquant des forces F1 et F2 pour plaquer les bords 4 et 5 de l'emballage contre le bord correspondant de la cuvette 6. A partir de ce moment, on active le film adhésif par chauffage ou par haute fréquence ou par tout autre moyen similaire obtenant ainsi le scellage du fond sur le bord du corps tubulaire 1. Par la suite on relâche les forces F1, F2, F3 et F4, et l'emballage retrouve sa forme définitive puisque les forces F3, F4 ainsi que l'écartement des mâchoires M1 et M2 sont prévus pour provoquer une déformation non permanente de l'emballage.By means of a punch P having the shape of the bowl 6 which will form the bottom, this bowl is placed between the jaws M1 and M2, the bowl thus being in its final position. Subsequently by means of two clamping members S1 and S2, opposing forces F3 and F4 are applied against the two opposite portions of the lateral surface of the package 1 and in particular in regions located under two movable jaws M3 and M4. The effect of this tightening is to expel at least part of the air still in the tubular body 1. Thereafter, while maintaining the tightening forces S3, S4, two jaws M3 and M4 are brought closer by applying forces F1 and F2 to press the edges 4 and 5 of the packaging against the corresponding edge of the bowl 6. From this moment, the adhesive film is activated by heating or by high frequency or by any other similar means thus obtaining the sealing of the bottom on the edge of the tubular body 1. Subsequently the forces F1, F2, F3 and F4 are released, and the packaging regains its final shape since the forces F3, F4 and the spacing of the jaws M1 and M2 are provided to cause non-permanent deformation of the packaging.

Quelle que soit la forme de la section transversale, autre que ronde, le procédé peut être utilisé avec succès.Whatever the shape of the cross-section, other than round, the process can be used with success.

Par la suite, l'emballage continue son cycle de fabrication tel que prévu dans le brevet précité du même déposant (ourlage ...).Thereafter, the packaging continues its manufacturing cycle as provided for in the aforementioned patent of the same applicant (hemming, etc.).

Ainsi, par un procédé simple on arrive à mettre en place une cuvette ayant la forme définitive sans que l'air se trouvant dans l'emballage freine la mise en place de cette cuvette puisqu'il peut se déplacer lors du déplacement de la cuvette par l'espace existant entre le bord déformé 4 et 5 (dessiné en traits mixtes sur la figure 1) et la cuvette et par la suite on arrive à chasser encore une partie supplémentaire de l'air en utilisant les organes de serrage S1 et S2.Thus, by a simple process we manage to set up a bowl having the final shape without the air being in the packaging slowing down the positioning of this bowl since it can move during the movement of the bowl by the space existing between the deformed edge 4 and 5 (drawn in dashed lines in FIG. 1) and the bowl and thereafter we manage to expel yet another part of the air by using the clamping members S1 and S2.

Dans le but de pouvoir procéder à une cadence très élevée de la mise en placed du fond 6 de l'emballage 1, on a muni la matrice de formage 7 de la cuvette du fond décrite dans la demande de brevet précitée du même inventeur, de canaux 8 reliés à une source d'aspiration (non représentée). Ainsi, lors de la mise en place du fond par le poinçon P, l'air chassé est aspiré à travers les canaux 8, ainsi que les éventuelles particules du produit emballé permettant ainsi d'éviter la contamination de la matrice de formage 7. Pour le reste, le procédé est identique à ce qu'il a été décrit précédemment.In order to be able to proceed at a very high rate of placing the bottom 6 of the package 1, the forming die 7 was provided with the bottom bowl described in the aforementioned patent application of the same inventor, channels 8 connected to a suction source (not shown). Thus, during the establishment of the bottom by the punch P, the expelled air is sucked through the channels 8, as well as any particles of the packaged product thus making it possible to avoid contamination of the forming matrix 7. For the rest, the process is identical to that which has been described previously.
