Description

PERFECTIONNEMENTS AUX RECIPIENTS SOUPLES
La présente invention concerne les récipients souples et plus particulièrement ceux du genre outre réalisés à partir d'un film de matiere plastique tubulaire et destinés à contenir notamment un produit liquide, pulvérulent ou granuleux.
IMPROVEMENTS ON FLEXIBLE CONTAINERS
The present invention relates to flexible containers and more particularly those of the kind further produced from a film of tubular plastic material and intended to contain in particular a liquid, pulverulent or granular product.

On utilise couramment un conditionnement de ce type pour la distribution par exemple de lait. Ce conditionnement est constitué d'une outre réalisée à partir d'un film tubulaire sur lequel on pratique une premiè- re soudure perpendiculaire aux bords du tube, puis apres remplissage, une seconde soudure parallèle à la première, le liquide se trouvant prison nier dans l'outre ainsi délimitée par les deux soudures transversales et séparée du reste du tube. A packaging of this type is commonly used for the distribution, for example, of milk. This packaging also consists of a tubular film on which a first weld is made perpendicular to the edges of the tube, then after filling, a second weld parallel to the first, the liquid being trapped in the skin thus delimited by the two transverse welds and separated from the rest of the tube.

Toutefois, la préhension et la manipulation d'une telle outre sont malaisées du fait de sa déformabilité permanente et qu'aucun organe de préhension ne soit prévu. However, the gripping and handling of such a addition are difficult because of its permanent deformability and that no gripping member is provided.

On a donc imaginé de munir ces outres de conditionnement de liquide d'organes facilitant leur manipulation. It has therefore been imagined to provide these bottles for packaging liquid organs facilitating their handling.

On a pensé, à cet effet, à conformer un organe de préhension dans un tronçon de film tubulaire constitutif de l'outre séparé de cette derfière par ladite seconde soudure. Cependant, une telle technique néce9- site un outillage complémentaire relativement complexe. It has been thought, for this purpose, to conform a gripping member in a section of tubular film constituting the skin separated from this latter by said second weld. However, such a technique requires relatively complex complementary tools.

On a imaginé également de rapporter en un endroit approprié de l'outre un organe de préhension tel qu'une anse rigide. Mais une telle opération se fait en reprise, une fois l'outre remplie et scellée et implique une phase supplémentaire dans le cycle de fabrication dont la durée s'accot sensiblement, ce qui réduit d'autant la cadence de fabrication et entraîne des frais supplémentaires non négligeables d'adaptation de la chaîne de fabrication. It has also been imagined to bring a gripping member such as a rigid handle to a suitable place in the skin. However, such an operation is carried out once the bottle has been filled and sealed and involves an additional phase in the manufacturing cycle, the duration of which is substantially increased, which reduces the rate of manufacture accordingly and entails additional costs. significant adaptation of the production chain.

La présente invention a précisément pour but de palier ces divers inconvénients en proposant une nouvelle technique de réalisation de récipients souples pourvus d'un organe de préhension rapporté, particulie- rement simple et facile à mettre en oeuvre avec les memes cadences de fabrication que celles des récipients souples du meme genre non pourvus d'organe de préhension. The object of the present invention is precisely to overcome these various drawbacks by proposing a new technique for producing flexible containers provided with an attached gripping member, particularly simple and easy to implement with the same production rates as those of flexible containers of the same kind not provided with a gripping member.

A cet effet, l'invention a pour objet un récipient souple destiné au conditionnement de produits, notamment liquides, pulvérulents ou granuleux, du type constitué par une outre tubulaire en matire thermoplas- tique fermée à ses deux extrémités par une soudure de scellement et pourvue d'un organe de préhension, caractérisé en ce que ledit organe de préhension est constitué par une languette en matière thermoplastique superposée à l'une des parois de l'outre et réunie à cette paroi par l'une desdites soudures de scellement. To this end, the invention relates to a flexible container intended for the packaging of products, in particular liquids, pulverulent or granular, of the type constituted by a tubular addition made of thermoplastic material closed at its two ends by a sealing weld and provided of a gripping member, characterized in that said gripping member is constituted by a tongue of thermoplastic material superimposed on one of the walls of the skin and joined to this wall by one of said sealing welds.

Dans cette languette peuvent avantageusement être pratiquées une ou plusieurs ouvertures facilitant la préhension. In this tab can advantageously be made one or more openings facilitating gripping.

L'invention concerne également un procédé pour l'obtention d'un tel récipient souple à partir d'un film tubulaire de matière thermosoudable, caractérisé en ce qu'on amène aux postes de soudage, en synchronisme avec le défilement du film tubulaire, une bande de matière thermoplastique, on soude simultanément ledit film et ladite bande plaquée latéralement au film, puis on coupe la bande, de manière à laisser à au moins l'une des extrémités de chaque récipient un tronçon de bande constituant ladite languette. The invention also relates to a method for obtaining such a flexible container from a tubular film of heat-sealable material, characterized in that one brings to the welding stations, in synchronism with the running of the tubular film, a strip of thermoplastic material, said film and said strip pressed laterally to the film are simultaneously welded, then the strip is cut, so as to leave at at least one of the ends of each container a section of strip constituting said tab.

Un tel procédé est remarquablement simple à mettre en oeuvre et ne réduit aucunement la cadence de fabrication des récipients souples car, en dehors des phases de soudage des deux extrémités des outres et de leur remplissage, la seule opération qui s'effectue est la découpe de la bande, laquelle est réalisée en un temps très bref au cours des temps d'arrêt du défilement du film tubulaire dans lequel sont réalisées les outres, temps d'arrêt nécessités par lesdites opérations de soudage et de remplissage. Cette phase supplémentaire de decoupe ne ralentit donc aucunement la cadence de fabrication des outres. Such a process is remarkably simple to implement and in no way reduces the rate of manufacture of the flexible containers because, apart from the phases of welding the two ends of the bottles and their filling, the only operation which is carried out is the cutting of the strip, which is produced in a very short time during the stopping times of the running of the tubular film in which the skins are made, stopping times required by said welding and filling operations. This additional cutting phase therefore in no way slows down the production rate of the wineskins.

D'autres caractéristiques et avantages ressortiront de la description qui va suivre d'un mode de réalisation d'une outre selon l'invention, description donnée à titre d'exemple uniquement et en regard du dessin annexé sur lequel
- fig. 1 représente une vue en élévation de face d'un récipient souple pourvu d'un organe de préhension conforme à l'invention,
- fig. 2 est une vue agrandie en coupe partielle suivant la ligne
II-II du récipient de la fig. ]; et
- fig. 3 est une vue illustrant le procédé de l'invention pour l'obtention du récipient de la fig. 1.
Other characteristics and advantages will emerge from the description which follows of an embodiment of a addition according to the invention, description given by way of example only and with reference to the appended drawing in which
- fig. 1 represents a front elevation view of a flexible container provided with a gripping member according to the invention,
- fig. 2 is an enlarged view in partial section along the line
II-II of the container of fig. ]; and
- fig. 3 is a view illustrating the method of the invention for obtaining the container of FIG. 1.

Le récipient des figures 1 et 2 est constitué d'une outre 1 réalisée à partir d'un film tubulaire en matiere plastique synthétique thermosoudable fermée à ses deux extrémités par une soudure de scellement symbolisée en 2. The container of FIGS. 1 and 2 consists of a further 1 made from a tubular film of heat-sealable synthetic plastic material closed at its two ends by a sealing weld symbolized in 2.

L'une des extrémités de l'outre est pourvue d'une languette rapportée 3 perforée d'une ou plusieurs ouvertures 4 facilitant la préhension
La languette 3 sensiblement rectangulaire est en matière thermoplastique et est soudée par l'un de ses bords longitudinaux à l'outre 1 au cours de la réalisation de la soudure de scellement 2, la languette 3 en position de repos étant plaquée contre l'outre, comme représenté en tiretés en 5 sur la fig. 2.
One end of the skin is provided with an attached tongue 3 perforated with one or more openings 4 facilitating gripping
The substantially rectangular tongue 3 is made of thermoplastic material and is welded by one of its longitudinal edges to the skin 1 during the production of the sealing weld 2, the tongue 3 in the rest position being pressed against the skin , as shown in dashed lines in 5 in FIG. 2.

La figure 3 illustre le procédé de réalisation d'une telle outre. Figure 3 illustrates the method of making such a addition.

Au cours de la fabrication des outres 1, une bande de matière thermoplastique dont des tronçons constitueront les languettes 3 est amenée contre l'une des faces des outres et scellée sur celles-ci aux endroits des soudures de scellement 2 des outres, ce scellement de ladite bande s'effectuant au cours de la réalisation des soudures 2. During the manufacturing of the bottles 1, a strip of thermoplastic material, sections of which will constitute the tongues 3, is brought against one of the faces of the bottles and sealed thereon at the places of the seal welds 2 of the bottles, this sealing of said strip being carried out during the production of the welds 2.

La réalisation de ces dernières provoque la séparation de chaque outre du reste du film tubulaire. Ensuite, la bande accolée à chaque outre est coupée en 6 et 7 aux longueurs désirées de façon à constituer sur chaque outre 1 une languette 3 rabattue sur l'outre. Il subsiste donc également sur chaque outre 1, à l'opposé de la languette 3, un tronçon de bande 8 de très faible longueur puisqu'il ne sert en fait à rien bien que l'on puisse envisager de munir chaque outre d'une languette à chaque extrémité. The realization of the latter causes the separation of each further from the rest of the tubular film. Then, the strip attached to each addition is cut in 6 and 7 to the desired lengths so as to constitute on each addition 1 a tongue 3 folded over the addition. There therefore also remains on each addition 1, opposite the tongue 3, a strip section 8 of very short length since it is in fact useless although we can consider providing each addition with a tongue at each end.

Bien entendu, la figure 3 ne fait qu'illustrer le procédé de l'invention. Pratiquement les outres individuelles sont réalisées une à une à la manière bien connue. On forme d'abord la soudure 2 inférieure de l'outre, ce qui la sépare du film tubulaire, on la remplit d'un produit liquide, pulvérulent ou granuleux, puis on forme la soudure 2 supérieure. Of course, FIG. 3 only illustrates the process of the invention. Practically the individual bottles are made one by one in the well known manner. First forming the lower weld 2 of the addition, which separates it from the tubular film, filling it with a liquid, pulverulent or granular product, then forming the upper weld 2.

La bande devant constituer les languettes 3 de préhension est amenée à partir d'une bobine d'alimentation en synchronisme avec la machine de conditionnement, ladite bande étant ensuite coupée par un système de coupe également synchronisé avec la machine. The strip to constitute the gripping tabs 3 is brought from a supply reel in synchronism with the packaging machine, said strip then being cut by a cutting system also synchronized with the machine.

La cadence de la machine de conditionnement n'est donc nullement réduite, la découpe de ladite bande s'effectuant durant le temps de remplissage de l'outre et/ou durant le temps de réalisation des soudures de scellement 2. The rate of the packaging machine is therefore in no way reduced, the cutting of said strip being carried out during the filling time of the addition and / or during the time of making the sealing welds 2.

La languette 3 peut comporter une ou plusieurs perforations ou n, en point comporter du tout. The tongue 3 may have one or more perforations or n, in point include at all.

La nature, l'épaisseur, les dimensions et la forme de la languette peuvent bien entendu varier dans de larges limites. Pour renforcer la languette celle-ci pourrait également être double ou tubulaire. The nature, thickness, dimensions and shape of the tongue can of course vary within wide limits. To strengthen the tongue, it could also be double or tubular.

Enfin, l'invention n'est pas limitée au mode de réalisation repré senté et décrit ci-dessus mais en couvre au contraire toutes les variantes.  Finally, the invention is not limited to the embodiment shown and described above, but on the contrary covers all variants.
