Description

La présente invention concerne un procédé d'obtention et de remplissage d'un conteneur souple de grande contenance.The present invention relates to a process for obtaining and filling a flexible container of large capacity.

A l'heure actuelle, les produits pulvérulents ou de très faible granulométrie sont contenus, pour le conditionnement en semi-vrac dans des conteneurs souples constitués de deux enveloppes.At the present time, powdery products or products of very small particle size are contained, for semi-bulk packaging in flexible containers made up of two envelopes.

Les conteneurs dont il est question dans la présente invention servent au conditionnement de charges de produits comprises dans la gamme d'environ 250 kg à 1 500 kg.The containers referred to in the present invention are used for packaging product loads in the range of about 250 kg to 1,500 kg.

Dans les conteneurs souples constitués de deux enveloppes de la technique antérieure, la partie résistante de l'emballage est une toile extérieure généralement en polypropylène. L'enveloppe interne dénommée sache est une gaine habituellement en polyéthyléne qui assure l'étanchéité. Le fond de la sache est soudé et sa gueule est ligaturée après le remplissage pour éviter toute entrée d'eau au contact du produit.In flexible containers made up of two envelopes of the prior art, the resistant part of the packaging is an outer fabric generally made of polypropylene. The internal envelope called sache is a sheath usually made of polyethylene which provides sealing. The bottom of the bag is welded and its mouth is ligated after filling to avoid any entry of water in contact with the product.

L'utilisation d'une sache donne satisfaction en ce qui concerne le problème d'étanchéité mais pose des problèmes de prix de revient. En effet, il faut prévoir un certain temps pour la mise en place convenable de la sache et pratiquer sur chaque côté deux ouvertures. Au moins l'une de ces ouvertures permet de sortir la partie supérieure de la sache ou gaine interne afin de l'appliquer sur la buse de remplissage.The use of a bag gives satisfaction with regard to the sealing problem but poses cost price problems. Indeed, it is necessary to allow a certain time for the proper positioning of the bag and to practice on each side two openings. At least one of these openings allows the upper part of the bag or internal sheath to be taken out in order to apply it to the filling nozzle.

En outre, le coût de la sache représente environ 15 % du prix du conteneur souple final.In addition, the cost of the bag is around 15% of the price of the final flexible container.

La présente invention a pour objet de proposer un conteneur qui ne comprend qu'une seule enveloppe.The object of the present invention is to provide a container which comprises only one envelope.

Grâce à la mise en oeuvre du procédé selon la présente invention, on peut supprimer l'utilisation de la sache interne et remédier aux problèmes exposés ci-dessus.Thanks to the implementation of the method according to the present invention, it is possible to eliminate the use of the inner bag and remedy the problems set out above.

Dans le conteneur obtenu dans la présente invention, il n'y a pas de fuite du produit à l'extérieur du conteneur et pas d'entrée d'humidité dans celui-ci.In the container obtained in the present invention, there is no leakage of the product outside the container and no entry of moisture into it.

La présente invention propose donc un procédé d'obtention et de remplissage d'un conteneur souple de grande contenance dans lequel dans une première étape on coud deux panneaux de toile rectangulaires le long de leurs grands côtés disposés verticalement, dans une deuxième étape on forme un premier chignon à la partie inférieure desdits deux panneaux de toile et on ligature ce chignon par un lien, lesdites deux premières étapes étant mises en oeuvre avant remplissage, dans une troisième étape on forme un deuxième chignon à la partie supérieure que l'on ligature par un lien (un tel procédé étant connu en soi) qui est caractérisé en ce qu'on réalise le deuxième chignon avant le remplissage, en ce qu'on prévoit une seule ouverture latérale dans la paroi du conteneur entre les deux chignons à proximité de la partie supérieure, en ce qu'on introduit une goulotte de remplissage dans l'ouverture, en ce qu'on procède au remplissage, en ce qu'on retire la goulotte et referme l'ouverture.The present invention therefore provides a method of obtaining and filling a flexible container of large capacity in which in a first step is sewn two rectangular canvas panels along their long sides arranged vertically, in a second step is formed a first bun at the bottom of said two canvas panels and this bun is ligated by a link, said first two steps being implemented before filling, in a third step a second bun is formed at the top which is ligated by a link (such a process being known per se) which is characterized in that the second bun is produced before filling, in that a single lateral opening is provided in the wall of the container between the two buns near the upper part, in that one introduces a filling chute into the opening, in that one proceeds to the filling, in that one withdraws the chute and closes the opening.

La présente invention concerne également les caractéristiques ci-après considérées isolément ou selon toutes leurs combinaisons techniquement possibles:

  • - on effectue une couture transversale sur le bas avant la formation du premier chignon;
  • - on effectue une couture transversale sur le haut avant la formation du deuxième chignon;
  • - on insère une sangle dans le deuxième chignon lors de sa formation;
  • - l'ouverture dans la paroi latérale du conteneur est formée par une interruption d'une couture latérale ou en fendant verticalement ladite paroi.
The present invention also relates to the characteristics below considered in isolation or in all their technically possible combinations:
  • - a transverse seam is made on the bottom before the formation of the first bun;
  • - a transverse seam is made on the top before the formation of the second bun;
  • - a strap is inserted into the second bun during its formation;
  • - The opening in the side wall of the container is formed by interrupting a side seam or by vertically slitting said wall.

On utilise deux panneaux de toile étanche et on insère et coll'e sur lesdits deux panneaux de toile par une colle thermofusible un cavalier de polyéthylène qui recouvre intérieurement chaque couture latérale sans être traversé par les fils de celle-ci et on referme au moyen, d'un cavalier étanche collé sur la face extérieure l'ouverture latérale qui a été pratiquée dans la paroi du conteneur entre le premier et le deuxième chignon;Two waterproof canvas panels are used and a polyethylene jumper which internally covers each lateral seam without being crossed by the threads of the latter and is closed and closed by means of a hot-melt adhesive, is inserted and glued onto said two canvas panels a watertight jumper glued on the outside face the lateral opening which has been made in the wall of the container between the first and the second bun;

- l'ouverture latérale entre le premier et le deuxième chignon a une dimension d'environ 50 cm ;

  • - les panneaux de toile sont en polypropylène imperméabilisé sur la face intérieure par un film de polypropylène solidaire desdits panneaux de toile et constituent une seule enveloppe ;
  • - le cavalier étanche collé sur la face extérieure est en polyéthylène.
    Divers avantages et caractéristiques supplémentaires de la présente invention ressortiront de la description détaillée ci-après faite en regard des dessins annexés sur lesquels ;
  • - Fig. 1 illustre schématiquement une ébauche du conteneur après la mise en oeuvre de certaines étapes du procédé.
  • - Fig. 2 illustre le conteneur avant l'étape de remplissage.
  • - Fig. 3 illustre le conteneur pendant l'étape de remplissage.
  • - Fig 4 illustre le conteneur souple de grande contenance obtenu par le procédé de l'invention dans son état final rempli.

Aux dessins annexés où, les mêmes chiffres de référence désignent des parties analogues, le conteneur souple de grande contenance obtenu par le procédé selon la présente invention est designé dans son ensemble par 1. Le conteneur 1 est constitué de deux panneaux de toile 2 comportant sur leur face intérieure un film de polypropylène. Le film de polypropylène est solidaire de chaque panneau de toile 2 de façon à constituer une seule enveloppe. Les panneaux de toile 2 sont habituellement en polypropylène.- The lateral opening between the first and the second bun has a dimension of approximately 50 cm;
  • - the canvas panels are made of polypropylene waterproofed on the inside by a polypropylene film secured to said canvas panels and constitute a single envelope;
  • - the waterproof jumper glued on the outside is made of polyethylene.
    Various advantages and additional characteristics of the present invention will emerge from the detailed description below made with reference to the appended drawings in which;
  • - Fig. 1 schematically illustrates a blank of the container after the implementation of certain steps of the method.
  • - Fig. 2 illustrates the container before the filling step.
  • - Fig. 3 illustrates the container during the filling step.
  • - Fig 4 illustrates the flexible container of large capacity obtained by the method of the invention in its final filled state.

In the accompanying drawings in which, the same reference numerals designate similar parts, the large flexible container obtained by the process according to the present invention is designed as a whole by 1. The container 1 consists of two canvas panels 2 comprising on their inner face a polypropylene film. The polypropylene film is integral with each canvas panel 2 so as to constitute a single envelope. The canvas panels 2 are usually made of polypropylene.

Les deux panneaux de toile 2 rectangulaires sont assemblés le long de leurs grands côtés par deux coutures latérales 3 en fil de polypropylène. Dans chacune des deux coutures latérales 3 est inséré et collé sur les extrémités de chaque panneau de toile 2, par une colle thermofusible,The two rectangular canvas panels 2 are assembled along their long sides by two lateral seams 3 made of polypropylene thread. In each of the two side seams 3 is inserted and glued to the ends of each canvas panel 2, with a hot-melt adhesive,

un cavalier 4 en polyéthyléne. Le cavalier 4 a pour fonction, d'une part d'interdire tout contact entre le produit situé a l'intérieur du conteneur 1 et, d'autre part, d'interdire également tout contact du produit avec les trous pratiqués dans les panneaux de toile 2 par les aiguilles des machines à coudre. Grâce a une telle réalisation des coutures latérales, il n'y a aucun contact possible au niveau du corps du conteneur 1 entre le produit et l'extérieur dudit conteneur. En effet, les coutures latérales 3 sont étanches de même que l'enveloppe unique constituée des panneaux de toile 2 revêtus intérieurement d'un film de polypropylène.a rider 4 in polyethylene. The jumper 4 has the function, on the one hand of prohibiting any contact between the product located inside the container 1 and, on the other hand, also of prohibiting any contact of the product with the holes made in the panels of canvas 2 by sewing machine needles. Thanks to such an embodiment of the side seams, there is no possible contact at the level of the body of the container 1 between the product and the exterior of said container. Indeed, the side seams 3 are waterproof as well as the single envelope consisting of canvas panels 2 coated internally with a polypropylene film.

Après avoir indiqué la façon dont on procède pour réaliser le corps proprement dit du conteneur 1, on décrit ci-après la mise en oeuvre du fond.After having indicated the procedure for producing the actual body of the container 1, the implementation of the base is described below.

On effectue tout d'abord une couture transversale 5. A titre d'exemple une telle couture transversale 5 est une couture du type surjet. On forme alors avec la partie inférieure des deux panneaux de toile 2 ainsi assemblés un premier chignon inférieur 6. On ligature ce chignon 6, par un lien 7. A titre d'exemple le lien serré 7 peut être appliqué à environ cinq centimètres au-dessus de la partie inférieure du chignon 6. Le lien 7 peut être en toute matière appropriée métallique ou synthètique. Il peut s'agir, par exemple, d'un lien en polypropylène. Le chignon 6, du fait de son serrage par le lien 7, empêche toute fuite de produit et toute entrée d'humidité par capillarité.First a transverse seam 5 is carried out. By way of example, such a transverse seam 5 is a seam of the overlock type. A first lower bun 6 is then formed with the lower part of the two canvas panels 2 thus assembled. This bun 6 is ligated by a link 7. By way of example, the tight link 7 can be applied at approximately five centimeters above above the lower part of the bun 6. The link 7 can be of any suitable metallic or synthetic material. It can be, for example, a polypropylene link. The bun 6, due to its tightening by the link 7, prevents any product leakage and any entry of moisture by capillary action.

La partie supérieure du conteneur est formée comme la partie inférieure. On réalise donc une autre couture transversale 8, par exemple du type surjet. On forme comme indiqué plus haut un deuxième chignon 9 en prenant soin d'insérer dans ledit deuxième chignon 9 une sangle 10 qui servira à permettre la préhension du conteneur final 1 au moyen, par exemple, d'un crochet 11. Bien entendu, au préalable, on ligature le chignon 9 avec un lien approprié 12. Le lien 12 peut être analogue au lien 7.The upper part of the container is formed like the lower part. Another transverse seam 8 is therefore produced, for example of the overlock type. A second bun 9 is formed as indicated above, taking care to insert into said second bun 9 a strap 10 which will serve to allow the gripping of the final container 1 by means, for example, of a hook 11. Of course, at the beforehand, the bun 9 is ligated with an appropriate link 12. The link 12 can be analogous to the link 7.

Après avoir réalisé comme indiqué ci-dessus, tant la partie inférieure que la partie supérieure, on prévoit une seule ouverture latérale 13. Cette ouverture latérale 13 peut être obtenue de deux manières.After having produced, as indicated above, both the lower part and the upper part, a single lateral opening 13 is provided. This lateral opening 13 can be obtained in two ways.

Selon un premier mode, on interrompt une des deux coutures latérales 3 ainsi que le collage du cavalier en polyéthylène 4 sur l'un des panneaux de toile 2 entre les deux chignons 6 et 9, de préférence à proximité du chignon 9. A titre d'exemple, une telle interruption peut représenter environ 50 cm.According to a first embodiment, one of the two lateral seams 3 is interrupted as well as the bonding of the polyethylene jumper 4 on one of the canvas panels 2 between the two buns 6 and 9, preferably near the bun 9. As a For example, such an interruption can represent approximately 50 cm.

Selon un deuxième mode, on pratique une ouverture latérale 13 en fendant un des panneaux de toile 2. L'ouverture lacérale 13 permet d'introduire une buse de remplissage 14 dans ladite ouverture 13. La buse 14 sert au remplissage du conteneur 1 comme indiqué par la flèche 15 et le produit 16 se trouve alors dans le conteneur 1. Après la fin du remplissage du conteneur 1, les deux lèvres de l'ouverture latérale 13 se rapprochent spontanément. Ces deux lèvres peuvent alors, après un certain temps de désaération du produit, être scellées par mise en place d'un cavalier de fermeture 17. Le cavalier 17 peut être du type auto-adhésif et être, à titre d'exemple en polyéthylène. En fait, il suffit de garantir l'étanchéité de l'ouverture latérale 13. Le collage d'un cavalier en polyéthylène 17 sur une interruption ou une fente de 50 cm environ, s'est révélé satisfaisant.According to a second embodiment, a lateral opening 13 is made by slitting one of the canvas panels 2. The lateral opening 13 makes it possible to introduce a filling nozzle 14 into said opening 13. The nozzle 14 is used for filling the container 1 as indicated by the arrow 15 and the product 16 is then in the container 1. After the filling of the container 1 has finished, the two lips of the lateral opening 13 spontaneously approach each other. These two lips can then, after a certain time of deaeration of the product, be sealed by placing a closing jumper 17. The jumper 17 can be of the self-adhesive type and be, for example made of polyethylene. In fact, it suffices to guarantee the watertightness of the lateral opening 13. The bonding of a polyethylene jumper 17 to an interruption or a slot of approximately 50 cm, has proved satisfactory.

Après la mise en oeuvre des différentes étapes comme indiqué dans la présente invention, on obtient le conteneur 1 dans l'état tel que représenté sur la figure 4.After the implementation of the various steps as indicated in the present invention, the container 1 is obtained in the state as shown in FIG. 4.
