Description

La présente invention concerne un conteneur étanche, souple, de grande contenance pour le conditionnement de produits pulvérulents ou de très faible granulométrie.The present invention relates to a tight, flexible container, of large capacity for the packaging of pulverulent products or of very small particle size.

De nos jours, les produits pulvérulents ou de très faible granulométrie sont contenus, pour le conditionnement en semi-vrac, dans des conteneurs souples constitués de deux enveloppes. Il s'agit de conteneurs susceptibles de conditionner des quantités de produits correspondant à des quantités de 250 kg à 1500 kg.Nowadays, powdery products or products with very small particle sizes are contained, for semi-bulk packaging, in flexible containers made up of two envelopes. These are containers capable of packaging quantities of products corresponding to quantities of 250 kg to 1500 kg.

L'enveloppe extérieure qui constitue la partie résistante.de l'emballage est une toile en polypropylène tandis que l'enveloppe intérieure est une gaine en polyéthylène qui assure l'étanchéité. Le corps de la gaine intérieure appelée sache est habituellement collé à l'enveloppe extérieure et son fond est soudé. Sa partie supérieure ou gueule est ligaturée après le remplissage afin d'éviter toute entrée d'eau au contact du produit.The outer casing which constitutes the resistant part of the packaging is a polypropylene fabric while the inner casing is a polyethylene sheath which provides sealing. The body of the inner sheath called sache is usually glued to the outer shell and its bottom is welded. Its upper part or mouth is ligated after filling in order to avoid any entry of water in contact with the product.

FR-A-2 450 754 décrit un sac imperméable de grande contenance pourvu d'une sache interne solidaire de l'enveloppe externe. Cette enveloppe externe présente une fente latérale et deux oeillets de levage opposés.FR-A-2 450 754 describes a large-capacity waterproof bag provided with an internal bag secured to the external envelope. This outer casing has a side slit and two opposite lifting eyes.

US-A-3 473 703 décrit un emballage pour des matières fluides. Il est prévu dans cet emballage un passage 22 qui est transformé en goulotte en le détachant du corps principal selon les lignes de soudage 20. Cette goulotte est une goulotte de vidage du contenu de l'emballage.US-A-3,473,703 describes a package for fluent materials. A passage 22 is provided in this packaging which is transformed into a chute by detaching it from the main body along the welding lines 20. This chute is a chute for emptying the contents of the packaging.

Un inconvénient des conteneurs étanches de grande contenance selon la technique, antérieure du type décrit ci- dessus est qu'il se produit très souvent une rupture de la sache du fait de la façon dont elle est mise en place.A disadvantage of leaktight containers of large capacity according to the prior art of the type described above is that very often a rupture of the bag due to the way it is put in place.

L'objet de la présente invention est de remédier au problème mentionné plus haut en apportant une plus grande sécurité au niveau de l'étanchéité et en facilitant l'utilisation pour le remplissage du conteneur et sa fermeture après remplissage.The object of the present invention is to remedy the problem mentioned above by providing greater security in terms of sealing and by facilitating use for filling the container and closing it after filling.

Selon la présente invention, on prévoit un conteneur étanche pour le conditionnement de produits pulvérulents ou de très faible granulométrie comprenant une enveloppe externe constituée de deux panneaux de toile assemblés par coutures tant latéralement que transversalement, une des coutures latérales étant interrompue à proximité de la partie supérieure ou gueule pour ménager une ouverture latérale, le fond cousu par une des coutures transversales étant rassemblé pour former un chignon inférieur qui est ligaturé par un lien tandis que la gueule est rassemblée et ligaturée par un ou plusieurs liens ou par un bandeau de toile ainsi qu'une sache interne collée sur les deux panneaux de toile et dont le fond est soudé, qui est caractérisé en ce que la sache présente à sa partie supérieure une partie tubulaire réalisée en effectuant une fente longitudinale et en soudant tant la partie longitudinale correspondant à la longueur d'un des bords de la fente que la partie transversale supérieure existant à partir de ladite fente et la plus éloignée de l'ouverture latérale, ladite partie tubulaire étant tirée à travers l'ouverture latérale pour former une goulotte de remplissage, laquelle est obturée après le remplissage au moyen d'un noeud avant de la rentrer à l'intérieur du conteneur.According to the present invention, a sealed container is provided for the packaging of powdered products. slow or of very small particle size comprising an external envelope made up of two canvas panels assembled by seams both laterally and transversely, one of the side seams being interrupted near the upper part or mouth to provide a lateral opening, the bottom sewn by one of the transverse seams being brought together to form a lower bun which is ligated by a link while the mouth is gathered and ligated by one or more links or by a canvas strip as well as an internal bag glued on the two canvas panels and whose bottom is welded, which is characterized in that the bag has at its upper part a tubular part produced by making a longitudinal slit and by welding both the longitudinal part corresponding to the length of one of the edges of the slit and the upper transverse part existing from said slot and furthest from the lateral opening, said tubular part is ant pulled through the side opening to form a filling chute, which is closed after filling with a knot before returning it inside the container.

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 represents the container of the invention being formed;
  • - Fig. 2 shows the container during filling;
  • - Fig. 3 shows the filled container in its final state;

Aux dessins annexés où les mêmes symboles de référence désignent des parties analogues, le conteneur selon la présente invention est désigné dans son ensemble par 1. Le conteneur 1 comprend une enveloppe externe constituée de deux panneaux de toile 2. Les panneaux de toile 2 sont avantageusement en polypropylène. Ils sont assemblés au niveau du fond, par une couture transversale 3 et au niveau de la gueule par une autre couture transversale 4. En outre, les panneaux de toile 2 sont également assemblés par deux coutures latérales 5 et 6. Une des coutures latérales, la couture 5 dans l'exemple représenté sur la fig. 1 est interrompue à proximité de la partie supérieure ou gueule pour ménager une ouverture latérale 7. Tant les coutures latérales 5, 6 que les coutures transversales 3, 4 peuvent être réalisées avec un fil- en polypropylène. Avant la réalisation finale de l'enveloppe externe, on insère dans celle-ci une gaine intérieure ou sache 8 de même largeur et ne comportant pas de soufflets. La sache 8 est habituellement en polyéthylène. Cette sache 8 est collée sur les deux panneaux de toile 2 par des cordons de colle thermofusible 9, de manière à obtenir un bon déploiement au moment du pré-gonflage et un positionnement correct par rapport à l'enveloppe externe. On évite ainsi tout risque de rupture de la sache 8 au moment du remplissage et on obtient donc une parfaite sécurité en ce qui concerne l'étanchéité. D'une façon connue, le fond de la sache 8 a été soudé. La sache 8 présente à sa partie supérieure une partie tubulaire 10 qui est obtenue en effectuant une fente longitudinale 11. Une soudure transversale 12 ainsi qu'une soudure longitudinale 13 assurent la formation de -la partie tubulaire 10 de la sache 8. Le fond de la sache 8, en-dessous de la soudure comporte une bavette 14 qui est prise dans la couture 3 du fond du conteneur 1. Le fond du conteneur 1 qui a été cousu comme on l'a indiqué plus haut est rassemblé en un chignon inférieur 15 qui est ligaturé par un lien approprié 16. La soudure transversale 12 s'étend sur environ 150 cm de la largeur de la gueule de la sache 8 alors que la soudure longitudinale 13 s'étend sur environ 50 cm. On comprend aisément que la couture transversale 4 de la gueule du conteneur 1 est effectuée sur toute la largeur sans prendre la sache 8 dans ladite couture 4. Cette gueule du conteneur 1 est rassemblée et ligaturée par un ou plusieurs liens ou par un bandeau de toile schématisé en 17. La partie tubulaire 10 de la sache 8 est tirée à travers l'ouverture latérale 7 pour former une goulotte de remplissage dans laquelle on insère, lors du remplissage du produit 19 une buse de remplissage 20. Le remplissage est effectué selon le sens de la flèche 21 de la fig. 2. La goulotte 18 est obturée après le remplissage du produit 19 au moyen d'un noeud 22 avant d'être rentrée à l'intérieur du conteneur 1.In the accompanying drawings where the same reference symbols designate similar parts, the container according to the present invention is generally designated by 1. The container 1 comprises an external envelope made up of two canvas panels 2. The canvas panels 2 are advantageously polypropylene. They are assembled at the bottom, by a transverse seam 3 and at the mouth by another transverse seam 4. In addition, the canvas panels 2 are also assembled by two side seams 5 and 6. One of the side seams, the seam 5 in the example shown in FIG. 1 is interrupted near the upper part or mouth to provide a lateral opening 7. Both the side seams 5, 6 and the transverse seams 3, 4 can be produced with a polypropylene thread. Before the final production of the external envelope, an internal sheath or bag 8 of the same width is inserted therein and does not have bellows. Bag 8 is usually made of polyethylene. This bag 8 is glued to the two canvas panels 2 by cords of hot-melt adhesive 9, so as to obtain a good deployment at the time of pre-inflation and a correct positioning relative to the external envelope. This avoids any risk of breakage of the bag 8 at the time of filling and therefore perfect security is obtained as regards sealing. In a known manner, the bottom of the bag 8 has been welded. The bag 8 has at its upper part a tubular part 10 which is obtained by making a longitudinal slot 11. A transverse weld 12 as well as a longitudinal weld 13 ensure the formation of the tubular part 10 of the bag 8. The bottom of the bag 8, below the weld has a flap 14 which is taken in the seam 3 of the bottom of the container 1. The bottom of the container 1 which has been sewn as indicated above is gathered in a lower bun 15 which is ligated by an appropriate link 16. The transverse weld 12 extends over approximately 150 cm of the width of the mouth of the bag 8 while the longitudinal weld 13 extends over approximately 50 cm. It is easily understood that the transverse seam 4 of the mouth of the container 1 is carried out over the entire width without taking the bag 8 in said seam 4. This mouth of the container 1 is assembled and ligated by one or more links or by a canvas band shown schematically in 17. The tubular part 10 of the bag 8 is pulled through the lateral opening 7 to form a filling chute into which, during filling of the product 19, a filling nozzle 20 is inserted. The filling is carried out according to the direction of arrow 21 in fig. 2. The chute 18 is closed after filling the product 19 by means of a node 22 before being returned to the interior of the container 1.

- Le remplissage du conteneur 1 s'effectue en suspendant ledit conteneur 1 par sa gueule ligaturée au crochet 23 de la station. Comme on l'a déjà indiqué, la goulotte 18 constituée par la partie tubulaire 10 de la sache 8 est enfilée autour de la buse de remplissage 20.- The filling of container 1 is carried out by suspending said container 1 by its mouth ligated to the hook 23 of the station. As already indicated, the chute 18 constituted by the tubular part 10 of the bag 8 is threaded around the filling nozzle 20.

Après le remplissage et le temps nécessaire à la désaération du produit 19, la goulotte 18 est nouée par un simple noeud de vache effectué manuellement et est rentrée à l'intérieur du conteneur 1. L'étanchéité du conteneur 1 à la gueule est ainsi totale.After filling and the time necessary for deaeration of the product 19, the chute 18 is knotted by a simple cow knot made manually and is returned inside the container 1. The tightness of the con content 1 in the mouth is thus total.

Grâce à la fonction de la sache 8 dont la structure a été décrite avec beaucoup de détails dans la présente invention, la présentation du conteneur 1 au poste de remplissage et la fermeture de la sache 8 nécessitent un temps beaucoup plus court qu'avec les conteneurs actuels qui présentent, à la gueule, un grand volume de gaine ou sache à manipuler.Thanks to the function of the bag 8, the structure of which has been described in great detail in the present invention, the presentation of the container 1 at the filling station and the closing of the bag 8 require a much shorter time than with the containers which present, at the mouth, a large volume of sheath or know how to handle.
