Description

  • La présente invention a pour objet un procédé et un dispositif pour améliorer la rigidité d'un conteneur sensiblement parallèlèpipédique en matière synthétique, ledit conteneur étant obtenu par conformation et soudures à partir d'un film constitué de ladite matière synthétique et venant envelopper le liquide à conditionner. The present invention relates to a method and a device for improving the rigidity of a substantially parallelepiped container made of synthetic material, said container being obtained by shaping and welding from a film made of said synthetic material and a member to wrap the liquid condition.
  • Elle concerne également les conteneurs ainsi obtenus. It also relates to the resulting container.
  • Des procédés et dispositifs de ce type sont déjà en eux-mêmes généralement connus. Methods and devices of this type are already in themselves generally known.
  • Ils ont par exemple, mais non limitativement, fait l'objet de brevets et/ou demandes de brevet au nom de la demanderesse. They have, for example, but not limited to the subject of patents and / or patent applications on behalf of the applicant.
  • Ainsi, on a proposé dans le brevet FR 2 554 785 un procédé pour rapporter une poignée rigide ou semi-rigide sur un sachet en matière synthétique souple. Thus, it has been proposed in patent FR 2554785 a method for reporting a handle rigid or semi-rigid to a flexible plastic bag. Celui-ci reste de mise en oeuvre relativement complexe en raison des problèmes de compatibilité entre les différents matériaux utilisés. It remains relatively complex implementation because of compatibility issues between the different materials used. D'autre part, la rigidification est strictement liée à la préhension, et ladite rigidification n'est pas assurée sur toutes les faces de manière uniforme. On the other hand, the stiffening is strictly linked to the grip, and said stiffener is not provided on all sides uniformly.
  • Dans le brevet FR 2 577 893 au nom de la demanderesse, il a été proposé de munir un coussin souple de moyens de rigidification et de stabilisation rigides, voire de nervures venues de matière avec le film. In patent FR 2,577,893 in the name of the Applicant, it has been proposed to provide a flexible bag stiffener means and rigid stabilization or venues ribs integral with the film. La mise en oeuvre en reste industriellement délicate. The implementation remains difficult industrially.
  • Par la demande FR 2 611 163, toujours au nom de la demanderesse, il est prévu de conformer un coussin rempli du liquide à conditionner puis d'enserrer ledit coussin et de le conformer par un manchon en matériau synthétique étirable formé à froid par des mâchoires mobiles en translation et en écartement l'une par rapport à l'autre. By application FR 2611163, all in the name of the Applicant, is provided to comply with a cushion filled with the liquid to be packaged and then to grip said bag and to shape the sleeve by a stretchable synthetic material cold-formed by jaws mobile in translation and spacing in relation to each other. Ce dispositif donne satisfaction mais est susceptible d'améliorations au niveau de la suite des interventions, car ici la rigidification intervient sur le coussin, déjà rempli, ce qui est source de problèmes potentiels sur le conteneur dudit coussin. This device is satisfactory but could be improved at the following interventions, because here comes the stiffening on the pillow, already completed, which is a source of potential problems on the container said cushion.
  • L'invention a pour objet de remédier à ces inconvénients de l'art antérieur, en proposant un procédé et un dispositif permettant d'obtenir un conteneur sensiblement parallèlèpipédique rigidifié de manière égale sur ses quatre faces verticales. The invention aims to remedy these disadvantages of the prior art by proposing a method and a device for obtaining a substantially parallelepiped container made rigid evenly on its four vertical faces.
  • Conformément à l'invention, ce résultat est obtenu avec un procédé pour améliorer la rigidité d'un conteneur sensiblement parallèlèpipédique souple étant obtenu par conformation et soudures à partir d'un film constitué de ladite matière synthétique et venant envelopper le liquide à conditionner, caractérisée en ce qu'il consiste à rapporter avant conformation sur la face dudit film ne venant pas ultérieurement au contact du liquide à conditionner une seconde couche d'un film de matière identique ou différente, qualifié de sur-film, ledit sur-film étant constitué de bandes multiples correspondant aux faces verticales du sachet final, lesdites bandes étant soudées sur ledit film avant sa conformation selon des lignes correspondant aux arêtes du conteneur parallèlèpipédique final. According to the invention, this is achieved with a method for improving the rigidity of a substantially parallelepiped flexible container being obtained by shaping and welding from a film made of said synthetic material and from wrapping the liquid to be packaged, characterized in that it consists in attaching before conformation on the side of said film not subsequently coming not in contact with the liquid to be packaged a second layer of an identical or different material film, described over-film, said over-film being made multiple bands corresponding to the vertical faces of the final sachet, said strips being welded to said film prior to its conformation along lines corresponding to the ridges of the final parallelepiped container.
  • L'invention a également pour objet un dispositif pour la mise en oeuvre dudit procédé, dispositif caractérisé en ce qu'il comporte, dans un ensemble de conformation d'un premier film de matière synthétique souple en conteneurs, un second ensemble d'alimentation en sur-film se déroulant perpendiculairement ou parallèlement audit premier film, ledit second film étant rapporté sur le premier film par des soudures longitudinales et transversales correspondant aux arêtes du conteneur parallèlèpipédique final. The invention also relates to a device for carrying out said method, a device characterized in that it comprises, in a set of configuration of a first flexible plastic film containers, a second supply assembly on-film taking place perpendicular or parallel to said first film, said second film being attached to the first film by longitudinal and transverse welds corresponding to the ridges of the final parallelepiped container.
  • Avantageusement, le sur-film pourra être imprimé et fera office d'étiquette. Advantageously, the on-film can be printed and will label office.
  • On comprendra mieux l'invention à l'aide de la description ci-après d'un mode de mise en oeuvre donné à titre d'exemple non limitatif, faite en référence aux dessins annexés dans lesquels : The invention will be better understood using the following description of an embodiment given by way of nonlimiting example, with reference to the accompanying drawings in which:
    • la figure 1 est une vue schématique de deux variantes de mise en oeuvre du procédé selon l'invention ; Figure 1 is a schematic view of two alternative embodiments of the method according to the invention;
    • la figure 2 est une illustration de la conformation d'un film obtenu par le procédé de la figure 1 ; Figure 2 is an illustration of the conformation of a film obtained by the method of Figure 1;
    • la figure 3 illustre les étapes ultérieures à savoir : 3 illustrates the subsequent steps, namely:
      • . . figure 3A : remplissage puis soudure transversale et découpe, Figure 3A: filling then transverse welding and cutting,
      • . . figure 3B : sachet avant conformation définitive, Figure 3B: sachet before final conformation,
      • . . figure 3C : formation des cornes et découpes de celles-ci, 3C: training horns and cuts thereof,
      • . . figure 3D : structure finale du conteneur. Figure 3D: final structure of the container.
  • On se référera tout d'abord à la figure 1. First of all, reference is made to Figure 1.
  • On a représenté un rouleau (1) de film principal (2) dont la face "inférieure" (3) viendra en contact avec le liquide à conditionner. a roller there is shown (1) primary film (2) whose face "lower" (3) come into contact with the liquid to be packaged.
  • Sur la face "supérieure" (4) est rapporté un sur-film (5) déroulé à partir d'une bobine se déroulant telle que (6) perpendiculairement au cheminement du film (2) ou (7) parallèlement au cheminement dudit film (2). On the "upper" side (4) is mounted on a film (5) unwound from a reel unwinding as (6) perpendicular to the path of the film (2) or (7) parallel to the path of said film ( 2).
  • Le sur-film (5) est posé sur le film (2), découpé par un ensemble (8) schématiquement représenté et soudé sur ledit film selon des lignes (9,10,11,13,14) longitudinales et deux lignes transversales (15,16). The on-film (5) is placed on the film (2), cut by an assembly (8) schematically represented and welded to said film along lines (9,10,11,13,14) longitudinal and two transverse lines ( 15,16).
  • Toutes ces opérations sont effectuées de manière indexée , pour qu'il y ait successivement avance du film (2), avance du film (5), découpe de la longueur de bande nécessaire, soudure des différentes lignes, puis avance à nouveau du film (2). All these operations are performed in an indexed manner, for there to successively advance the film (2) advance the film (5), the tape cutting length necessary welding of the different lines, then again advance the film ( 2).
  • En aval, on prévoiera la pose d'un opercule de bouchage (17), par exemple comme décrit dans le brevet FR 2 600 974 au nom de la demanderesse. Downstream, provision will be made placing a closure member (17), for example as described in patent FR 2,600,974 in the name of the Applicant.
  • Puis le film (2) muni de son sur-film et des soudures (9,14) déterminant trois panneaux principaux (18,19,20) et deux demi-panneaux (21,22) latéraux est amené sur un conformateur (23) représenté à la figure 2. Then the film (2) provided with its over-film and welded seams (9,14) determining three principal panels (18,19,20) and two half-panels (21,22) side is fed to a shaper (23) shown in Figure 2.
  • Ce conformateur est du type décrit dans le brevet FR 2 554 785 au nom de la demanderesse et ne sera donc pas décrit plus en détail. The former is of the type described in FR 2554785 in the name of the applicant and will therefore not be described in detail.
  • Les panneaux délimités par les soudures verticales déterminant les faces verticales du conteneur final. The panels separated by vertical welds determining the vertical faces of the final container. Les demi-panneaux latéraux seront soudés entre eux et pourront à cette occasion enserrer un anneau (24) de préhension du conteneur final. The half-panels side will be welded together and will on that occasion a grip ring (24) for gripping the final container.
  • Les deux demi-panneaux latéraux (21,22) sont ainsi reliés entre eux et forment une face du sachet final par soudure verticale sur le conformateur (23). The two lateral half-panels (21.22) are thus interconnected and form one side of the final bag by vertical welding on the shaper (23).
  • Puis de manière classique, il y a remplissage de la gaine ainsi conformée (25), soudure transversale et découpe en (26) représentée à la figure 3A pour arriver à l'unité (27) de la figure 3B. Then conventionally, there is filling of the sheath thus formed (25), transverse welding and cut-out (26) shown in Figure 3A to reach the unit (27) of Figure 3B.
  • Il reste à conformer les cornes par soudure-découpe selon par exemple le brevet FR 2 566 321 au nom de la demanderesse (figure 3C) pour parvenir à l'emballage final (28) représenté à la figure 3D. It remains to abide by the horns welding-cutting by eg FR 2566321 in the name of the plaintiff (Figure 3C) to reach the final package (28) shown in Figure 3D.
  • On notera que l'ensemble fonctionne de manière séquentielle et indexée. Note that all works sequentially and indexed.
  • Entre chaque bande de sur-film rapportée sur le film principal subsiste une zone sur laquelle est rapporté l'opercule de bouchage et qui servira, en coopérant à cette fin avec la précédente, à la formation du fond, du dessus et des cornes du conteneur. Between each strip of film attached to the main film remains an area in which is reported the cap and capping to serve, cooperating to that end with the previous one, to form the bottom, top and horns of the container .
