Description

La présente invention concerne le domaine des sachets refermables comprenant, sur leur embouchure, des dispositifs de fermeture conçus pour permettre de multi-ouvertures/fermetures successives à la demande.The present invention relates to the field of reclosable bags comprising, on their mouth, closure devices designed to allow multiple openings / closures on demand.

Plus précisément, la présente invention concerne le domaine des dispositifs de fermeture comprenant des éléments de fermeture complémentaires, par exemple deux éléments profilés de type mâle/femelle complémentaires.More specifically, the present invention relates to the field of closure devices comprising complementary closure elements, for example two complementary male / female type profile elements.

De nombreux types de sachets comprenant de tels éléments assurant la fonction de dispositifs de fermeture, ont déjà été proposés.Many types of sachets comprising such elements providing the function of closure devices, have already been proposed.

On a représenté sur la figure 1 annexée, un exemple de réalisation de dispositif de fermeture connu conforme au document US-6761481 .We have shown on the figure 1 attached, an embodiment of known closure device according to the document US 6761481 .

Sur cette figure 1, on aperçoit un dispositif de fermeture comprenant un élément mâle 10 et un élément femelle 20.On this figure 1 , there is a closure device comprising a male element 10 and a female element 20.

Le document WO-A-02/26590 divulgue un dispositif de fermeture pour sac ou sachet comprenant des éléments de fermeture complémentaires de type en tête de flèche et, respectivement, gorge à bords convergents et comprenant en plus des éléments additionnels formés soit, selon la figure 3A, d'un élément mâle arrondi et d'un élément femelle complémentaire, soit, selon la figure 3B, de deux pavés complémentaires en regard.The document WO-A-02/26590 discloses a closure device for a bag or bag comprising complementary closure elements of arrow head type and, respectively, with convergent edge grooves and further comprising additional elements formed either according to the figure 3A , a rounded male element and a complementary female element, or, according to the figure 3B , two complementary cobblestones opposite.

Les documents US-6182337 et EP-1375369 décrivent d'autres dispositifs de fermeture pour sac ou sachet comprenant des éléments de fermeture complémentaires et comprenant des moyens additionnels d'étanchéité complémentaires, respectivement de type convexe et concave.The documents US 6182337 and EP-1375369 describe other closure devices for bags or bags comprising complementary closure elements and comprising complementary additional sealing means, convex and concave respectively.

Le document US 2004/0252915 décrit une variante de dispositif de fermeture pour sac ou sachet comprenant des moyens additionnels adaptés pour se séparer en cas de surpression interne au sachet, afin de former un évent.The document US 2004/0252915 discloses an alternative closure device for bag or bag comprising additional means adapted to separate in case of internal overpressure of the bag, to form a vent.

La présente invention a maintenant pour objectif de perfectionner les dispositifs de fermeture connus afin d'améliorer l'étanchéité obtenue lors de la fermeture de ceux-ci.It is now an object of the present invention to improve the known closure devices in order to improve the sealing obtained when closing them.

Ce but est atteint selon la présente invention grâce à un dispositif du type défini ou revendication 1 annexée.This object is achieved according to the present invention by means of a device of the type defined or appended claim 1.

La présente invention concerne également les sacs ou sachets équipés de tels dispositifs.The present invention also relates to bags or sachets equipped with such devices.

D'autres caractéristiques, buts et avantages de la présente invention apparaîtront 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 précédemment évoquée représente un exemple de dispositif de fermeture conforme à l'état de la technique,
  • la figure 2 représente un mode de réalisation d'un dispositif de fermeture conforme à la présente invention, et
  • les figures 3 à 7 annexées représentent cinq variantes de réalisation 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:
  • the figure 1 previously mentioned represents an example of a closure device according to the state of the art,
  • the figure 2 represents an embodiment of a closure device according to the present invention, and
  • the Figures 3 to 7 attached represent five embodiments according to the present invention.

On a représenté sur la figure 2 annexée, un dispositif de fermeture 100 conforme à la présente invention. Ce dispositif de fermeture 100 comprend une paire de profilés de fermeture complémentaires : un élément profilé mâle 160 et un élément profilé femelle 170 complémentaire.We have shown on the figure 2 attached, a closure device 100 according to the present invention. This closure device 100 comprises a pair of complementary closure profiles: a male profile element 160 and a complementary female profile element 170.

De façon connue en soi, l'élément mâle 160 et l'élément femelle 170 sont solidaires de voiles supports respectifs 112, 122. Ces voiles 112, 122 peuvent être conçus pour être rapportés et fixés, par exemple par soudure thermique, sur un film destiné à composer un sac ou sachet. Ou encore ces voiles 112, 122 peuvent être intégrés lors de la fabrication, dans le film destiné à constituer le sac ou sachet. En d'autres termes, l'ensemble de fermeture 100 conforme à la présente invention peut être conçu pour être rapporté sur un film destiné à former le sachet par soudure des voiles support 112, 122, ou encore être venu de matière avec le film destiné à constituer le sac ou sachet (par exemple par extrusion mono-matière ou coextrusion bi- ou multi-matière avec ce film).In a manner known per se, the male element 160 and the female element 170 are integral with respective support webs 112, 122. These webs 112, 122 may be designed to be attached and fixed, for example by thermal welding, on a film intended to compose a bag or sachet. Or again these sails 112, 122 may be integrated during manufacture, in the film intended to constitute the bag or bag. In other words, the closure assembly 100 according to the present invention may be designed to be attached to a film intended to form the bag by welding the support webs 112, 122, or be integral with the film intended to constitute the bag or bag (for example by single-material extrusion or bi-or multi-material coextrusion with this film).

On a représenté sur la figure 3 une variante de réalisation selon laquelle les éléments de fermeture complémentaires 160 et 170 sont remplacés par des structures de crochets.We have shown on the figure 3 an alternative embodiment in which the complementary closure elements 160 and 170 are replaced by hook structures.

De tels moyens de fermeture complémentaires 160, 170 à base d'éléments mâle/femelle ou de crochets, voire de tous moyens équivalents, par exemple de structures du type velours-crochet, sont bien connus de l'homme de l'art et ne seront donc pas décrits dans le détail par la suite.Such complementary closure means 160, 170 based on male / female elements or hooks, or any equivalent means, for example velvet-hook type structures, are well known to those skilled in the art and do not will not be described in detail later.

Comme on l'a évoqué précédemment, selon l'invention, le dispositif comprend en outre, en sus des éléments de fermeture complémentaires 160 et 170, deux éléments profilés additionnels 110 et 120 de type mâle/femelle complémentaires. L'élément mâle 110 possède une excroissance 111 de section droite convexe arrondie sans arête et l'élément femelle 120 définissant un berceau de réception 121 incurvé concave complémentaire.As has been mentioned above, according to the invention, the device further comprises, in addition to closure elements complementary 160 and 170, two additional profile elements 110 and 120 of complementary male / female type. The male element 110 has an outgrowth 111 of rounded convex cross-section without edges and the female element 120 defining a complementary concave curved receiving cradle 121.

Les profilés additionnels 110 et 120 sont prévus de préférence sur l'intérieur du sachet par rapport aux moyens de fermeture 160 et 170.The additional profiles 110 and 120 are preferably provided on the inside of the bag relative to the closing means 160 and 170.

De préférence, dans le cadre de l'invention, l'excroissance 111 est avantageusement convexe circulaire de révolution autour d'un axe parallèle au plan moyen du voile support 112.Preferably, in the context of the invention, the protrusion 111 is advantageously circular convex of revolution about an axis parallel to the mean plane of the support web 112.

En variante cependant, l'excroissance 111 peut être plus globalement ovoïde, c'est-à-dire de section droite arrondie sans arête comme indiqué précédemment. On a illustré sur la figure 7 annexée une telle variante de réalisation de l'excroissance 111.Alternatively, however, the protrusion 111 may be more generally ovoid, that is to say of rounded straight section without edge as indicated above. We illustrated on the figure 7 annexed such an embodiment variant of the outgrowth 111.

L'élément femelle 120 définit également une gorge concave ou berceau 121 complémentaire, c'est-à-dire possédant une enveloppe interne également arrondie sans arête et de préférence de section droite complémentaire de celle de l'excroissance 111.The female element 120 also defines a concave groove or cradle 121 complementary, that is to say having an inner envelope also rounded without ridge and preferably of complementary cross section to that of the protrusion 111.

On a représenté sur les figures 2 et 3, des variantes de réalisation selon lesquelles l'élément femelle 120 couvre un angle limité à 180° autour de l'élément mâle 110.We have shown on Figures 2 and 3 , variant embodiments in which the female element 120 covers an angle limited to 180 ° around the male element 110.

On a représenté sur la figure 4, une autre variante de réalisation selon laquelle l'élément femelle 120 couvre un angle inférieur à 180° autour de l'élément mâle 110.We have shown on the figure 4 , another variant embodiment in which the female element 120 covers an angle less than 180 ° around the male element 110.

L'homme de l'art comprendra que les éléments 110 et 120 sont destinés à venir en contact lors de la fermeture d'un sachet et permettent ainsi d'assurer l'étanchéité entre les deux voiles 112, 122 et par conséquent entre les films de sachets liés à ceux-ci.Those skilled in the art that the elements 110 and 120 are intended to come into contact during closing of a bag and thus make it possible to ensure sealing between the two webs 112, 122 and therefore between the films of sachets related to these.

On a représenté sur la figure 5, une autre variante de réalisation selon laquelle l'élément femelle 120 possède une épaisseur variable au niveau de sa gorge 121. Plus précisément, dans ce cas l'épaisseur de l'élément femelle 120 diminue en éloignement du voile support 122.We have shown on the figure 5 , another variant embodiment in which the female element 120 has a variable thickness at its groove 121. More specifically, in this case the thickness of the female element 120 decreases away from the support web 122.

On a représenté sur la figure 6, une variante inverse selon laquelle l'épaisseur de l'élément femelle 120 croît progressivement en éloignement du voile support 122.We have shown on the figure 6 , an inverse variant according to which the thickness of the female element 120 grows progressively away from the support web 122.

Les variations d'épaisseur de l'élément femelle 120 telles qu'illustrées sur les figures 5 et 6 peuvent être déterminées en fonction du matériau utilisé, de l'étanchéité requise, de la pression interne au sachet, et de l'effort acceptable lors de l'engagement des profilés de fermeture.The variations in thickness of the female element 120 as illustrated in FIGS. Figures 5 and 6 can be determined according to the material used, the required sealing, the internal pressure of the bag, and the acceptable force when engaging the closure profiles.

A titre d'exemple non limitatif, le dispositif de fermeture conforme à la présente invention, et en particulier l'élément mâle 110, est de préférence réalisé par extrusion, très préférentiellement en un matériau souple, avantageusement à base de polyoléfine ou de copolymère d'éthylène.By way of nonlimiting example, the closure device according to the present invention, and in particular the male element 110, is preferably made by extrusion, very preferably in a flexible material, advantageously based on polyolefin or copolymer of 'ethylene.

Selon divers modes de réalisation, l'un au moins des éléments mâle 110 ou femelle 120 est relié au voile support 112, 122 qui lui est associé par l'intermédiaire d'un pied 113, 123.According to various embodiments, at least one of the male 110 or female 120 elements is connected to the support web 112, 122 which is associated with it by means of a foot 113, 123.

Un tel pied 113, 123 permet d'autoriser un certain débattement, c'est-à-dire un déplacement relatif entre l'élément mâle 110 et l'élément femelle 120 pour assurer une parfaite étanchéité au système quelles que soient les éventuelles sollicitations en désalignement entre les éléments 110 et 120, opérées par le sachet lui-même.Such a foot 113, 123 allows to allow a certain deflection, that is to say a relative displacement between the male element 110 and the female element 120 to ensure a perfect seal to the system whatever the possible stresses in misalignment between the elements 110 and 120, operated by the bag itself.

Selon une première variante de réalisation qui ne fait pas partie de l'invention, seul l'élément mâle 110 comporte un pied 113 reliant l'excroissance 111 au voile support 112. Ce pied 113 autorise un certain débattement de l'excroissance 111 pour lui permettre de s'adapter au berceau 121.According to a first alternative embodiment which is not part of the invention, only the male member 110 has a foot 113 connecting the protrusion 111 to the support web 112. The stand 113 allows a certain clearance of the protrusion 111 for him allow to adapt to cradle 121.

Selon une deuxième variante de réalisation qui ne fait pas partie de l'invention, seul l'élément femelle 120 est relié au voile support 122 par l'intermédiaire d'un pied 123. Ce pied 123 autorise également un certain débattement du berceau 121 pour lui permettre de s'adapter sur l'excroissance 111.According to a second variant embodiment which does not form part of the invention, only the female element 120 is connected to the support web 122 by way of a foot 123. This foot 123 also allows a certain travel of the cradle 121 for allow him to adapt to the outgrowth 111.

Selon l'invention, l'élément mâle 110 et l'élément femelle sont reliés au voile support (112, 122) qui leur est associé par l'intermédiaire d'un pied (113, 123).According to the invention, the male element 110 and the female element are connected to the support web (112, 122) associated with them by means of a foot (113, 123).

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 particular embodiments which have just been described but extends to any variant within its spirit.

La présente invention peut s'appliquer à la réalisation de sac ou sachet à base de tout matériau. Il s'agit de préférence de film en matériau thermoplastique, en particulier à base de polyéthylène moyenne densité ou haute densité, voire toute autre matière plastique, ainsi que le cas échéant, un matériau composite.The present invention can be applied to the realization of bag or bag based on any material. It is preferably a film of thermoplastic material, in particular based on medium-density or high-density polyethylene, or even any other plastic material, as well as, where appropriate, a composite material.

Par ailleurs, la présente invention s'applique également aux dispositifs de fermeture actionnés par curseur.Furthermore, the present invention also applies to slider actuated closure devices.

Un tel curseur, connu en soi, n'est pas représenté sur les figures annexées pour simplifier l'illustration.Such a cursor, known per se, is not shown in the accompanying figures to simplify the illustration.

L'homme de l'art sait néanmoins que généralement un tel curseur comprend une base qui porte deux flasques latéraux et un muret central. Les flasques et le muret définissent en combinaison deux canaux, en partie en moins non parallèles. Ces canaux reçoivent les éléments respectifs mâle et femelle. Un tel curseur facilite l'ouverture et la fermeture des sachets, puisqu'il suffit de déplacer le curseur pour, selon le sens de déplacement de celui-ci, écarter ou mettre en prise les profilés en raison du non parallélisme des canaux.Those skilled in the art nevertheless know that generally such a slider comprises a base which carries two lateral flanges and a central wall. The flanges and the wall define in combination two channels, partly less nonparallel. These channels receive the respective male and female elements. Such a slider facilitates the opening and closing of the bags, since it is sufficient to move the cursor to, depending on the direction of movement thereof, spread or engage the profiles due to the non-parallelism of the channels.
