Description

La présente invention concerne le domaine des sachets équipés d'un ensemble de fermeture adapté pour permettre des ouvertures/fermetures multiples successives à la demande.The present invention relates to the field of sachets equipped a closure assembly adapted to allow successive multiple openings / closings upon request.

Plus précisément encore, la présente invention concerne la fabrication de tels sachets à l'aide d'ensembles de fermeture comportant deux profilés en matériau thermoplastique comprenant des éléments complémentaires, adaptés pour être alternativement mis en prise pour permettre la fermeture des sachets et séparés pour permettre l'ouverture des sachets et l'accès à leur contenu.More precisely, the present invention relates to the manufacture of such bags using closure assemblies comprising two profiles of thermoplastic material comprising elements complementary, adapted to be alternatively allow the bags to be closed and separated to allow the opening of sachets and access to their contents.

Généralement les éléments complémentaires précités sont formés de structures en crochet ou d'éléments respectivement mâle et femelle prévus sur les deux profilés.Generally the additional elements mentioned above are formed of hook structures or elements respectively male and female provided on both profiles.

On trouvera des exemples de processus connus de fabrication de tels sachets dans les documents FR-A-2475261 et FR-A-2778362.Examples of known processes for the manufacture of such bags in FR-A-2475261 and FR-A-2778362.

L'objectif de la présente invention est d'améliorer l'état de la technique.The object of the present invention is to improve the state of the technical.

Ce but est atteint selon la présente invention grâce à un ensemble de fermeture pour sachet refermable comportant, sur son extrémité longitudinale avant, un repère permettant de contrôler l'orientation dudit ensemble de fermeture lors de sa mise en place sur un film constituant le corps des sachets.This object is achieved according to the present invention by means of a closure assembly for a resealable bag having, on its front longitudinal end, a reference mark to control the orientation of said closure assembly during its installation on a film constituting the body of the sachets.

Ledit repère conforme à la présente invention peut être un repère tactile, c'est-à-dire un élément en creux ou en saillie. Cependant, de préférence, le repère est formé d'un repère visuel, par exemple un liseré longitudinal coloré.Said reference mark according to the present invention may be a tactile mark, that is to say a hollow or protruding element. However, preferably, the marker is formed of a visual cue, for example a colored longitudinal border.

La présente invention concerne également les sachets réalisés à l'aide d'un tel ensemble de fermeture ainsi qu'un procédé et une machine de fabrication de tels sachets.The present invention also relates to sachets made using such a closure assembly as well as a method and a machine for making such bags.

D'autres caractéristiques, buts et avantages de la présente invention apparaítront à la lecture de la description détaillée qui va suivre, et en regard des dessins annexés, donnés à titre d'exemples non limitatifs et sur lesquels :

  • la figure 1 représente une vue schématique en perspective partielle d'une machine de fabrication de sachets incorporant un ensemble de fermeture conforme à la présente invention,

  • les figures 5, 6, 7, 8 et 9 représentent des vues schématiques de cinq variantes d'ensembles de fermeture conformes à la présente invention.
Other features, objects and advantages of the present invention will appear on reading the detailed description which follows, and with reference to the appended drawings, given by way of non-limiting examples and in which:
  • FIG. 1 represents a schematic partial perspective view of a bag-making machine incorporating a closure assembly according to the present invention,
  • FIG. 2 schematically illustrates the hypothesis of a correct alignment of closure assembly on such a machine,

  • FIG. 4 represents an alternative embodiment of a bag-making machine using a closure assembly according to the present invention, and
  • Figures 5, 6, 7, 8 and 9 show schematic views of five variants of closure assemblies according to the present invention.

On a représenté sur les figures 1 et 4 annexées, deux machines de fabrication en automatique de sachets incorporant un ensemble de fermeture.Is shown in Figures 1 and 4 attached, two machines of manufacture in automatic sachets incorporating a set of closing.

La structure générale de ces machines est connue en soi. Elle ne sera donc pas décrite dans le détail par la suite.The general structure of these machines is known per se. She does not will not be described in detail later.

On rappelle cependant que les machines de fabrication en automatique de sachets (dénommées généralement FFS pour l'expression "Form Fill and Seal" en anglais) sont conçues pour fabriquer, remplir et fermer en automatique les sachets. Elles comprennent généralement un col de formage 10 qui reçoit en entrée un film 20 à l'état plan en provenance d'un dérouleur 30 et qui fournit en sortie le film 20 conformé en tube, une goulotte de remplissage 40 qui débouche dans ce col de formage 10 et par conséquent dans ledit tube, des moyens 50 de soudure longitudinale pour fermer le tube longitudinalement et des moyens 60 aptes à générer séquentiellement une première soudure transversale avant qu'un produit ne soit introduit dans le tube par la goulotte de remplissage 40, puis une seconde soudure transversale quand le produit a été introduit dans le tube, pour fermer un emballage autour de ce dernier.It is recalled, however, that automatic bagging (usually called FFS for the phrase "Form Fill and Seal" are designed to Automatically manufacture, fill and close the bags. They generally comprise a forming neck 10 which receives as input a film 20 in the plane state from a rewinder 30 and which provides at the outlet the film 20 shaped as a tube, a filler neck 40 which opens into this forming neck 10 and consequently into said tube, longitudinal welding means 50 for closing the tube longitudinally and means 60 able to generate sequentially a first transversal weld before a product is introduced in the tube by the filler neck 40, then a second transversal weld when the product has been introduced into the tube, for close a package around it.

Comme on le voit sur les figures 1 et 4 annexées, les machines précitées comportent en outre des moyens pour acheminer sur le film 20 un ensemble de fermeture 100 à partir d'une réserve 110. Plus précisément encore, selon la figure 1, l'ensemble de fermeture 100 est acheminé sur le film 20 parallèlement à la direction de déplacement du film 20 sur le col 10. Plus précisément encore selon la figure 1, l'ensemble de fermeture 100 est acheminé entre les deux bords longitudinaux du film 20 rapprochés pour former le tube précité. Dans ce cas l'ensemble de fermeture 100 est fixé sur les deux bords du film 20 par les moyens de soudure longitudinale 50. Cette disposition n'est cependant pas limitative, en ce sens que l'ensemble de fermeture 100 peut être acheminé sur le film 20 en un lieu différent des bords longitudinaux de celui-ci et/ou fixé sur le film 20 à l'aide de moyens différents des moyens 50.As can be seen in Figures 1 and 4 annexed, the machines mentioned above furthermore comprise means for conveying on the film 20 a closure assembly 100 from a reserve 110. More precisely again, according to FIG. 1, the closure assembly 100 is routed on the film 20 parallel to the direction of travel of the film 20 on the neck 10. More precisely still according to FIG. the closure assembly 100 is conveyed between the two edges longitudinals of the film 20 brought together to form the aforesaid tube. In this case the closure assembly 100 is fixed on both edges of the film 20 by longitudinal welding means 50. That provision is not however not limiting, in that the closure assembly 100 can be routed on film 20 at a different location from the edges of the latter and / or fixed on the film 20 by means of different from the means 50.

On a représenté sur la figure 4, une variante selon laquelle l'ensemble de fermeture 100 n'est pas acheminé sur le film 20 parallèlement à la direction de déplacement de celui-ci, mais au contraire, transversalement à sa direction de déplacement. On notera qu'alors que selon la figure 1, l'ensemble de fermeture 100 peut être acheminé sous forme d'une bande continue sur le film 20, lors d'un dépôt transversalement à la direction de déplacement du film 20, comme illustré sur la figure 4, l'ensemble de fermeture 100 est de préférence acheminé sur le film 20 sous forme de tronçons individualisés.FIG. 4 shows a variant according to which the closure assembly 100 is not routed on the film 20 parallel to the direction of movement of it but at the contrary, transversely to its direction of displacement. We will note whereas, according to FIG. 1, the closure assembly 100 can be routed in the form of a continuous strip on the film 20, during a deposition transversely to the direction of movement of the film 20, as illustrated in FIG. 4, the closure assembly 100 is preferably conveyed on the film 20 in the form of sections individualized.

Les moyens d'acheminement, de sectionnement et de soudure de l'ensemble de fermeture 100 sur le film 20, tant en disposition longitudinale conforme à la figure 1, qu'en disposition transversale conforme à la figure 4, sont bien connus de l'homme de l'art et ne seront donc pas décrits dans le détail par la suite.Means for conveying, sectioning and welding of the closure assembly 100 on the film 20, both in disposition longitudinal section according to Figure 1, in transverse arrangement according to Figure 4, are well known to those skilled in the art and do not will not be described in detail later.

On pourra à cet égard se référer d'ailleurs aux documents FR-2778362 et FR-2745261 précités.In this respect reference may be made to documents FR-2778362 and FR-2745261 supra.

Par ailleurs, la présente invention n'est bien entendu pas limitée à la mise en oeuvre sur des machines de fabrication en automatique du type illustré sur les figures 1 et 4 annexées. Moreover, the present invention is of course not limited to the implementation on automatic manufacturing machines of the type illustrated in Figures 1 and 4 attached.

De préférence, comme on l'a schématisé sur les figures 1 et 4, l'ensemble de fermeture 100 est conditionné sous forme d'un rouleau 110 avant son acheminement sur le film 20 au niveau du poste de fabrication.Preferably, as schematized in FIGS. 1 and 4, the closure assembly 100 is packaged in the form of a roll 110 before it was sent to film 20 at the police station manufacturing.

L'ensemble de fermeture 100 est réalisé à base de matériau thermoplastique. Il comprend deux profilés 102, 104, comprenant respectivement des éléments complémentaires 103, 105 adaptés pour être alternativement mis en prise pour permettre la fermeture des sachets et séparer pour permettre l'ouverture des sachets et l'accès à leur contenu.The closure assembly 100 is made of material thermoplastic. It comprises two profiles 102, 104, comprising respectively complementary elements 103, 105 adapted for alternatively be put in place to allow the closure of bags and separate to allow the opening of sachets and access to their content.

Par ailleurs, les deux profilés 102, 104 sont portés par des voiles support respectifs 101, 106 généralement parallèles entre eux.Moreover, the two profiles 102, 104 are worn by sails respective support 101, 106 generally parallel to each other.

Comme indiqué précédemment, dans le cadre de la présente invention, l'ensemble de fermeture 100 comporte sur son extrémité longitudinale avant (le terme "avant" est pris en référence au sens d'introduction sur la machine de fabrication) un repère 108 permettant de contrôler l'orientation dudit ensemble de fermeture 100 lors de sa mise en place sur le film 20 constituant le corps des sachets.As indicated previously, in the context of this invention, the closure assembly 100 has on its end front longitudinal (the term "before" is taken as a reference to the meaning introduction on the manufacturing machine) a reference 108 allowing to control the orientation of said closure assembly 100 during its placed on the film 20 constituting the body of the bags.

Le repère 108 s'étend typiquement, parallèlement à la direction longitudinale de l'ensemble, sur une longueur de quelques centimètres sur l'extrémité longitudinale avant de l'ensemble de fermeture 100, typiquement de l'ordre de 10cm.The reference 108 typically extends parallel to the direction longitudinal of the whole, over a length of a few centimeters on the front longitudinal end of the closure assembly 100, typically of the order of 10 cm.

Comme on l'a évoqué précédemment, le repère 108 est de préférence formé d'un repère visuel tel qu'un liseré coloré d'une couleur se distinguant du reste de l'ensemble de fermeture.As mentioned above, the reference 108 is preferably formed of a visual cue such as a border colored with a color distinguished from the rest of the closure assembly.

On a schématisé un tel liseré coloré 108 sur les figures 5, 7 et 9 annexées.Such a colored border 108 has been schematised in FIGS. 5, 7 and 9 attached.

L'invention n'est cependant pas limitée à cette variante de réalisation. Comme schématisé sur les figures 6 et 8, par exemple, le repère 108 peut être formé d'un repère tactile soit par exemple un élément en creux type rainure, ou en saillie type nervure.The invention is however not limited to this variant of production. As schematized in Figures 6 and 8, for example, the reference numeral 108 may be formed of a tactile mark or for example a recessed element type groove, or projecting type rib.

De préférence, le repère 108 est placé de manière dissymétrique sur la largeur de l'ensemble de fermeture 100, plus précisément sur la surface (extérieure par exemple) de l'un des voiles support 101 ou 106. Comme on l'a évoqué précédemment, le repère 108 permet de garantir l'orientation correcte de l'ensemble de fermeture sur la machine de fabrication.Preferably, the reference 108 is placed asymmetrically over the width of the closure assembly 100, more precisely on the surface (exterior for example) of one of the support webs 101 or 106. As mentioned above, the reference 108 makes it possible to guarantee the correct orientation of the closure assembly on the machine of manufacturing.

A cette fin, de préférence, on prévoit un repère 108 non seulement sur l'extrémité longitudinale avant de l'ensemble de fermeture 100, mais également sur l'extrémité longitudinale arrière dudit ensemble de fermeture.For this purpose, preferably, there is provided a reference 108 not only on the front longitudinal end of the set of closure 100, but also on the rear longitudinal end said closure assembly.

Ainsi, comme on le voit sur la figure 2, il suffit d'aligner le repère 108 prévu sur l'extrémité longitudinale avant d'un ensemble de fermeture acheminé sur la machine de fabrication, sur le repère 108 de l'extrémité arrière d'un ensemble de fermeture 100 en cours d'utilisation sur la machine, pour garantir l'orientation correcte du profilé.Thus, as seen in Figure 2, it is sufficient to align the reference 108 provided on the front longitudinal end of a set of closure routed on the manufacturing machine, on the reference 108 of the rear end of a closure assembly 100 in use on the machine, to ensure correct orientation of the profile.

La figure 3 illustre au contraire le cas d'une erreur d'orientation, en cas de désalignement du repère 108 prévu sur l'extrémité avant d'un ensemble de fermeture acheminé, par rapport à l'extrémité arrière d'un ensemble en cours d'utilisation. Une telle erreur peut résulter par exemple d'un vrillage ou torsion de l'ensemble de fermeture 100, entre la réserve 110 et la machine de fabrication.FIG. 3 illustrates on the contrary the case of an orientation error, in case of misalignment of the mark 108 provided on the front end of a closure assembly conveyed relative to the rear end of a together in use. Such an error may result in example of a twisting or twisting of the closure assembly 100, between the reserve 110 and the manufacturing machine.

Une orientation correcte de l'ensemble de fermeture 100 est notamment décisive lorsque l'ensemble de fermeture 100 comprend deux voiles support 101, 106 présentant des largeurs différentes ou encore lorsque les deux voiles supports 101, 106 sont réunis sous forme d'un ensemble en U comme illustré sur la figure 2, ou encore lorsque les voiles supports 101, 106 sont réunis sous forme d'une forme plus complexe, par exemple en W comme illustré sur la figure 8.Correct orientation of the closure assembly 100 is especially decisive when the closure assembly 100 comprises two support webs 101, 106 having different widths or again when the two supporting webs 101, 106 are united in form a U-shaped assembly as shown in FIG. 2, or when the support webs 101, 106 are united in the form of a more complex, for example W as illustrated in Figure 8.

L'orientation correcte de l'ensemble de fermeture 100 est également primordiale lorsque des zones choisies de l'ensemble de fermeture 100 comportent des moyens localisés adaptés pour faciliter la fixation de l'ensemble de fermeture 100 sur le film 20, par exemple sous forme de traitements localisés ou encore de structures telles que des stries localisées ou tout autre moyen équivalent. The correct orientation of the closure assembly 100 is also paramount when selected areas of the set of closure 100 include localized means adapted to facilitate the fixing the closure assembly 100 on the film 20, for example under forms of localized treatments or structures such as localized streaks or any other equivalent means.

L'homme de l'art comprendra par ailleurs que le repère préconisé dans le cadre de la présente invention permet de faciliter la mise en place de l'ensemble de fermeture 100 puisqu'il suffit d'aligner le repère 108 pour garantir un fonctionnement correct, et par conséquent permet d'améliorer les cadences de fabrication, la dissymétrie des éléments de fermeture (mâle de forme excentrée, voiles décalés) étant en général très difficile à repérer pour un opérateur non averti sans un tel repère conforme à la présente invention.Those skilled in the art will also understand that the reference in the context of the present invention makes it possible to facilitate the setting up the closure assembly 100 since it is sufficient to align the 108 to ensure correct operation, and therefore improves the production rates, the asymmetry of closure elements (off-center male, staggered sails) being usually very difficult to spot for an unsophisticated operator without a such mark according to the present invention.

Bien entendu la présente invention n'est pas limitée aux modes de réalisation particuliers qui viennent d'être décrits mais s'étend à toute variante conforme à son esprit.Of course, the present invention is not limited to the modes particular embodiments which have just been described but any variant in accordance with his spirit.

En particulier, la présente invention s'applique à tout ensemble de fermeture quel que soit son matériau constitutif.In particular, the present invention applies to all together closing whatever its constituent material.

On notera que la présente invention permet d'améliorer sensiblement les cadences de production en limitant les rebus dus à une mauvaise orientation, et ce sans grever le prix de revient des ensembles de fermeture 100, dans la mesure où le repère tactile ou visuel 108 est limité à l'extrémité longitudinale avant, voir le cas échéant également à l'extrémité longitudinale arrière de l'ensemble de fermeture 100.It should be noted that the present invention makes it possible to improve production rates by limiting the scrap due to bad orientation, and this without burdening the cost price of the sets of closure 100, insofar as the tactile or visual mark 108 is limited at the front longitudinal end, see if applicable also at the rear longitudinal end of the closure assembly 100.

La présente invention peut s'appliquer à tout type d'ensemble de fermeture compatible avec l'invention.The present invention can be applied to any type of set of closure compatible with the invention.

On a représenté sur les figures 5, 6, 8 et 9 annexées, des éléments complémentaires 103, 105 de type mâle/femelle, tandis que l'on a représenté sur les figures 7 des éléments complémentaires 103, 105 de type crochets complémentaires. La présente invention s'applique à tous ces modes de réalisation et toute variante équivalente.FIGS. 5, 6, 8 and 9, shown in FIGS. complementary elements 103, 105 of the male / female type, while FIG. 7 shows complementary elements 103, 105 of complementary hook type. The present invention applies to all these embodiments and any equivalent variant.

On a représenté sur les figures 5, 6 et 7 annexées, des variantes de réalisation selon lesquelles les voiles support 101, 106 sont séparés et de préférence de largeurs différentes. Comme illustré sur les figures 5 et 6, les deux voiles support 101, 106 peuvent être centrés ou dissymétriques comme illustrés sur la figure 7.FIGS. 5, 6 and 7 are shown in the drawings. according to which the support webs 101, 106 are separated and preferably of different widths. As illustrated in FIGS. and 6, the two support webs 101, 106 may be centered or asymmetrical as shown in Figure 7.

On a représenté sur la figure 9, une variante de réalisation selon laquelle l'ensemble de fermeture 100 est équipé de curseurs 120. La structure générale de tels curseurs bien connue en soi ne sera pas décrite dans le détail par la suite. On rappelle cependant, que généralement les curseurs 120 comprennent une embase 122 portant deux voiles latéraux 124, 126 et une semelle centrale 128 qui définit avec les deux voiles latéraux 124, 126, deux couloirs 127, 128 non parallèles recevant respectivement l'un des deux profilés 102, 104. Le déplacement du curseur 120 dans un sens assure l'engagement des éléments complémentaires 103, 105. Le déplacement du curseur 120 dans le sens opposé tend à séparer les éléments complémentaires 103, 105.FIG. 9 shows a variant embodiment according to which the closure assembly 100 is equipped with sliders 120. general structure of such sliders well known per se will not be described in detail later. It is recalled, however, that generally sliders 120 comprise a base 122 carrying two lateral sails 124, 126 and a central sole 128 which defines with both side sails 124, 126, two lanes 127, 128 not parallel receiving respectively one of the two sections 102, 104. The moving the cursor 120 in one direction ensures the commitment of complementary elements 103, 105. Moving the cursor 120 in the opposite direction tends to separate the complementary elements 103, 105.

La présente invention s'applique à l'ensemble des variantes combinées précitées. C'est-à-dire que, bien que ces dispositions ne soient pas illustrées en totalité sur les figures annexées pour simplifier l'illustration, l'on peut combiner au moins l'un quelconque des moyens suivants :

  • des éléments complémentaires de type mâle/femelle ou crochets avec
  • des voiles supports 101, 106 séparés ou réunis, par exemple en U ou en W, avec
  • des voiles supports 101, 106 symétriques ou dissymétriques, avec
  • des voiles supports 101, 106 comportant ou non des moyens ou des structures de traitement facilitant la fixation, avec
  • un repère 108 de type visuel ou tactile,
  • un ensemble de fermeture comprenant ou non un curseur.
The present invention applies to all of the aforementioned combined variants. That is, although these arrangements are not fully illustrated in the accompanying figures to simplify the illustration, at least one of the following means may be combined:
  • complementary elements of the male / female type or hooks with
  • support webs 101, 106 separated or joined, for example U or W, with
  • symmetrical or asymmetrical support webs 101, 106, with
  • support webs 101, 106 with or without means or processing structures facilitating fixation, with
  • a reference 108 of the visual or tactile type,
  • a closure assembly with or without a slider.

De préférence, le repère 108 est formé sur l'ensemble de fermeture lors de l'extrusion de celui-ci ou en sortie d'extrusion.Preferably, the reference 108 is formed on the set of closure during extrusion thereof or extrusion output.
