Plus précisément, la présente invention concerne le domaine des sachets d'emballage comprenant des moyens d'ouverture/fermeture susceptibles de multiples ouvertures et fermetures successives, par exemple et non limitativement sous forme de profilés complémentaires. Le document EP-A-1 321 381 illustre un exemple de sachet d'emballage connu, susceptible de multiples ouvertures et fermetures successives. Ce sachet comprend un soufflet replié sur lui-même et maintenu dans cette position par un élément amovible, permettant selon les cas, une utilisation unique ou multiple. Il comprend aussi un second élément assurant une ouverture refermable, placé sur l'extrémité du soufflet. Bien que prometteur, le sachet d'emballage décrit dans ce document EP-A-1 321 381, n'a pas connu le succès commercial attendu. Le but de la présente invention est de perfectionner les sachets connus. Un but particulier de la présente invention est de proposer des sachets destinés à recevoir un contenu emballé sous forte pression, par exemple des couches de bébés ou équivalents, tout en permettant un accès aisé au contenu dès le premier retrait. Ce but est atteint dans le cadre de la présente invention, grâce à un sachet d'emballage comprenant au moins un soufflet replié contre une face du corps de sachet et maintenu dans cette position par un élément de liaison amovible, caractérisé par le fait qu'il comprend en outre un élément adapté pour assurer une ouverture refermable qui s'étend transversalement à la ligne de pliage du soufflet et couvre toute la largeur du soufflet et au moins une partie substantielle du corps de sachet. L'homme de l'art comprendra à la lecture de la description détaillée qui va suivre que le sachet conforme à la présente invention permet en particulier, grâce à la disposition spécifique de l'élément assurant l'ouverture refermable, un accès aisé à la totalité du contenu du sachet, alors que les sachets conformes à l'état de la technique conforme au document EP-A-1 321 381 ne permettent qu'un accès limité par la section droite du soufflet. Selon une autre caractéristique avantageuse de la présente invention, l'élément adapté pour assurer une ouverture refermable couvre tout le corps de sachet. Selon une autre caractéristique avantageuse de la présente invention, le sachet comprend deux soufflets repliés contre des faces du corps de sachet diamétralement opposées et maintenus dans cette position par des éléments de liaison amovible respectifs. Selon une autre caractéristique avantageuse de l'invention, l'élément adapté pour assurer une ouverture refermable comprend un élément de fermeture susceptible de multiples ouvertures/fermetures. Selon une autre caractéristique avantageuse de la présente invention, le sachet comporte des moyens évitant que l'élément de fermeture susceptible de multiples ouvertures/fermetures ne soit sollicité par le contenu du sachet quand ledit au moins un soufflet est maintenu replié par l'élément de liaison amovible. La présente invention concerne également un procédé de réalisation d'emballage qui comprend les étapes consistant à équiper le soufflet d'un sachet, d'un élément adapté pour assurer une ouverture refermable qui s'étend transversalement à la ligne de pliage du soufflet et couvre toute la largeur du soufflet et au moins une partie substantielle du corps de sachet, à replier sur lui-même le soufflet formé dans un corps de sachet et maintenir le soufflet dans cette position par un élément de liaison amovible. La présente invention concerne également un dispositif de fabrication d'emballage comprenant des moyens aptes à équiper le soufflet d'un sachet, d'un élément adapté pour assurer une ouverture refermable qui s'étend transversalement à la ligne de pliage du soufflet et couvre toute la largeur du soufflet et au moins une partie substantielle du corps de sachet, des moyens aptes à replier sur lui- même le soufflet formé dans un corps de sachet et des moyens aptes à générer une liaison amovible apte à maintenir le soufflet dans cette position. 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 :The present invention relates to the field of packaging sachets.

Those skilled in the art will understand from reading the detailed description that follows that the bag according to the present invention allows in particular, thanks to the specific arrangement of the element ensuring the reclosable opening, easy access to the entire contents of the bag, while the bags according to the state of the art according to EP-A-1 321 381 only allow limited access by the cross section of the bellows. According to another advantageous characteristic of the present invention, the element adapted to ensure a resealable opening covers the entire bag body.

- la figure 6 représente une vue en coupe transversale d'un ensemble de fermeture conforme à la présente invention équipé d'un curseur,FIG. 6 represents a cross-sectional view of a closure assembly according to the present invention equipped with a slider,
- les figures 7 et 8 représentent d'autres variantes conformes à la présente invention. On a représenté schématiquement sur les figures 1 et 2 annexées, un sachet conforme à la présente invention, à deux stades successifs de sa fabrication. Comme on le voit sur la figure 1, à l'origine, le sachet conforme à la présente invention comprend un corps de sachet 10 globalement tubulaire présentant une embouchure d'ouverture 12 et un fond 14 à son extrémité opposée. De préférence, le corps de sachet 10 est défini par quatre parois principales orthogonales entre elles. Sa section est ainsi globalement carré ou rectangulaire. Deux de ces parois sont illustrées sur la figure 1 sous les références 15 et 16. Les deux parois additionnelles sont respectivement parallèles et perpendiculaires à chacune de ces deux parois 15 et 16. Les parois du sachet peuvent faire l'objet de nombreux modes de réalisation. Il s'agit de préférence de parois en matériau thermoplastique. Ces parois peuvent être mono ou multi-couche(s) et mono ou multi-matériau(x). Le cas échéant, il peut s'agir d'un support papier revêtu d'une couche de matériau thermoplastique, ou encore d'une couche thermoplastique métallisée. Le sachet 10 peut être réalisé à l'aide d'une feuille unique ou de plusieurs feuilles, par exemple deux feuilles soudées entre elles au niveau de leurs bords, de préférence selon des arêtes reliant les parois principales, par exemple l'arête commune aux parois 15 et 16. Comme on l'a évoqué précédemment, dans le cadre de la présente invention, une partie 20 du corps de sachet 10, ici adjacente au fond 14, est repliée sur elle-même sous forme d'un soufflet. La partie 20 du sachet 10 repliée sous forme d'un soufflet possède une longueur .1 sensiblement égale à deux fois la largeur .2 du sachet. Les longueurs .1 et largeur .2 précitées du sachet sont considérées perpendiculairement à la ligne 22 de pliage du soufflet. L'opération de pliage précitée est schématisée par une flèche référencée P sur la figure 1. Le soufflet ainsi obtenu à partir du fond 14 est référencé 24 sur la figure 2. Comme on le voit sur la figure 2, de préférence le soufflet 24 couvre ainsi la totalité de la section du sachet de sorte qu'après réalisation du soufflet 24, au niveau du fond, le sachet 10 présente une triple épaisseur sous forme de couches référencées 25, 26 et 27 sur la figure 2. Le soufflet 24 est maintenu dans cette position par un élément de liaison amovible. Celui-ci peut faire l'objet de nombreuses variantes de réalisation. Selon un premier mode de réalisation, l'élément de liaison amovible précité peut être formé d'une bande autocollante. Une telle bande autocollante peut être prévue sur l'extrémité du sachet et du soufflet sous forme de la bande référencée 30 sur la figure 1, ou encore sur l'une des parois 16 du sachet destinée à recevoir l'extrémité du soufflet, sous forme de la bande référencée 32 sur la figure 1, ou encore de deux bandes autocollantes complémentaires correspondant aux deux bandes 30 et 32 représentées sur la figure 1. (Ces deux bandes 30 et 32 étant portées en contact lors du pliage du soufflet 24). Les bandes 30 et/ou 32 précitées s'étendent parallèlement à la ligne de pliage 22 du soufflet, sensiblement sur toute la hauteur .3 du sachet, ladite hauteur .3 étant considérée parallèlement à la ligne de pliage 22. Selon une autre variante de réalisation, le moyen de liaison amovible peut être formé d'éléments complémentaires situés respectivement au niveau des bandes 30 et 32 précitées représentées sur la figure 1, c'est-à-dire l'un sur l'extrémité du sachet coïncidant avec l'extrémité du soufflet 24 et l'autre au niveau d'une paroi 16 du corps de sachet destinée à recevoir l'extrémité du soufflet 24 et précitée. A titre d'exemple non limitatif, de tels éléments complémentaires peuvent être formés de structures complémentaires de type velours/crochet ou encore de profilés mâle/femelle complémentaires, ou même de structures en crochets complémentaires (éventuellement actionnés par un curseur). De tels éléments de liaison sont bien connus de l'homme de l'art et ne seront donc pas décrits dans le détail par la suite. Dans le cadre de la présente invention, le sachet comporte en outre au moins un élément de fermeture, susceptible de multiples ouvertures/fermetures. Un tel ensemble de fermeture est référencé 50 sur les figures annexées. Comme on l'a indiqué précédemment, dans le cadre de la présente invention, cet élément 50 adapté pour assurer une ouverture refermable s'étend transversalement à la ligne de pliage 22 du soufflet et couvre toute la largeur du soufflet et au moins une partie substantielle du corps de sachet. Il permet ainsi un accès aisé à l'ensemble du contenu du sachet. De préférence, le sachet comporte des moyens évitant que l'élément de fermeture 50 ne soit sollicité par le contenu du sachet quand le soufflet est maintenu replié par un élément de liaison 30, 32. A titre d'exemple non limitatif, l'ensemble de fermeture 50 est de préférence prévu sur une arête d'un soufflet, transversalement à la ligne de pliage 22. L'ensemble de fermeture 50 peut lui-même faire l'objet de nombreuses variantes. Il peut s'agir d'un élément autocollant, d'éléments complémentaires de type velours-/crochet, d'éléments complémentaires de type mâle/femelle ou encore d'éléments complémentaires de type crochet. On a représenté sur la figure 6 annexée une variante avantageuse de la présente invention dans laquelle l'élément de fermeture 50 est ainsi formé de deux profilés complémentaires 52, 54 comprenant respectivement un élément 53 de type mâle et un élément 55 complémentaire de type femelle. Tous ces moyens sont bien connus de l'homme de l'art. Ils ne seront donc pas décrits dans le détail par la suite. Le cas échéant, ces moyens d'ouverture/fermeture composant l'élément 50 peuvent être commandés par un curseur 60. Un tel curseur a été schématisé sur la figure 6 annexée. Là encore, il peut faire l'objet de nombreux modes de réalisation. Un tel curseur 60 comprend de préférence une semelle 62 qui porte deux toiles latérales 64, 65 et un muret central 66 définissant entre eux deux canaux 67, 68 non parallèles recevant respectivement au moins le sommet de l'un des deux voiles support 52, 54 dudit au moins un élément de fermeture 50 de sorte que selon le sens de déplacement du curseur 60, celui-ci sollicite l'élément 50 respectivement à l'ouverture et à la fermeture. Le cas échéant, mais cette disposition n'est pas impérative, le muret central 66 peut pénétrer entre les profilés complémentaires 53, 55. Une fois le soufflet 24 situé au niveau du fond 14, replié et maintenu par les moyens de liaison 30 et 32 associés, le sachet 10 peut être rempli sous pression de manière conventionnelle par l'embouchure- Figures 7 and 8 show other variants according to the present invention. FIGS. 1 and 2 show a schematic representation of a bag according to the invention at two successive stages of its manufacture. As seen in FIG. 1, the pouch according to the invention originally comprises a generally tubular bag body 10 having an opening mouth 12 and a bottom 14 at its opposite end. Preferably, the bag body 10 is defined by four main walls orthogonal to each other. Its section is thus generally square or rectangular. Two of these walls are illustrated in Figure 1 under the references 15 and 16. The two additional walls are respectively parallel and perpendicular to each of these two walls 15 and 16. The walls of the bag can be subject to many embodiments. It is preferably walls of thermoplastic material. These walls can be single or multi-layer (s) and mono or multi-material (x). If necessary, it may be a paper support coated with a layer of thermoplastic material, or a metallized thermoplastic layer. The bag 10 can be made using a single sheet or several sheets, for example two sheets welded together at their edges, preferably along edges connecting the main walls, for example the edge common to the walls 15 and 16. As mentioned above, in the context of the present invention, a portion 20 of the bag body 10, here adjacent to the bottom 14, is folded back on itself in the form of a bellows. The portion 20 of the bag 10 folded in the form of a bellows has a length substantially equal to twice the width of the bag. The above lengths .1 and width .2 of the bag are considered perpendicular to the line 22 of folding the bellows. The aforementioned folding operation is shown schematically by an arrow referenced P in Figure 1. The bellows thus obtained from the bottom 14 is referenced 24 in Figure 2. As seen in Figure 2, preferably the bellows 24 covers thus the entire section of the bag so that after completion of the bellows 24, at the bottom, the bag 10 has a triple thickness in the form of layers referenced 25, 26 and 27 in Figure 2. The bellows 24 is maintained in this position by a removable connecting element. This can be the subject of many variants. According to a first embodiment, the aforementioned removable connecting element may be formed of a self-adhesive strip. Such a self-adhesive strip may be provided on the end of the bag and the bellows in the form of the strip referenced 30 in FIG. 1, or on one of the walls 16 of the bag intended to receive the end of the bellows, in the form of of the band referenced 32 in Figure 1, or two complementary adhesive strips corresponding to the two strips 30 and 32 shown in Figure 1. (These two strips 30 and 32 being brought into contact during the folding of the bellows 24). The aforementioned strips 30 and / or 32 extend parallel to the fold line 22 of the bellows, substantially over the entire height of the bag 3, said height 3 being considered parallel to the fold line 22. According to another variant of FIG. realization, the removable connection means may be formed of complementary elements located respectively at the bands 30 and 32 above shown in Figure 1, that is to say one on the end of the bag coinciding with the end of the bellows 24 and the other at a wall 16 of the bag body for receiving the end of the bellows 24 and above. By way of nonlimiting example, such complementary elements may be formed of complementary structures of velvet / hook type or complementary male / female profiles, or even complementary hook structures (possibly actuated by a slider). Such connecting elements are well known to those skilled in the art and will therefore not be described in detail later. In the context of the present invention, the bag further comprises at least one closure element, capable of multiple openings / closures. Such a closure assembly is referenced 50 in the accompanying figures. As previously indicated, in the context of the present invention, this element 50 adapted to ensure a resealable opening extends transversely to the fold line 22 of the bellows and covers the entire width of the bellows and at least a substantial portion of the bag body. It thus allows easy access to all the contents of the sachet. Preferably, the bag comprises means preventing the closing element 50 from being biased by the contents of the bag when the bellows is held folded by a connecting element 30, 32. By way of nonlimiting example, the assembly closure member 50 is preferably provided on an edge of a bellows transverse to the fold line 22. The closure assembly 50 may itself be subject to numerous variations. It may be a self-adhesive element, complementary elements of velvet- / hook type, complementary elements of the male / female type or complementary hook-type elements. FIG. 6 shows an advantageous variant of the present invention in which the closing element 50 is thus formed of two complementary sections 52, 54 respectively comprising a male-type element 53 and a female-type complementary element 55. All these means are well known to those skilled in the art. They will not be described in detail later. Where appropriate, these opening / closing means constituting the element 50 may be controlled by a slider 60. Such a slider has been schematized in the appended FIG. 6. Again, it can be the subject of many embodiments. Such a slider 60 preferably comprises a sole 62 which carries two lateral canvases 64, 65 and a central wall 66 defining between them two non-parallel channels 67, 68 respectively receiving at least the top of one of the two support webs 52, 54 of said at least one closing element 50 so that in the direction of movement of the slider 60, the slider 60 urges the element 50 respectively to the opening and closing. If so, but this provision is not imperative, the central wall 66 can penetrate between the complementary profiles 53, 55. Once the bellows 24 located at the bottom 14, folded and held by the connecting means 30 and 32 associated, the bag 10 can be pressure filled in a conventional way by the mouth
12 et obturé au niveau de l'embouchure 12 par tout moyen classique approprié. A l'utilisation, pour permettre l'accès au contenu du sachet, il suffit de rompre l'élément de liaison 30, 32, pour déployer le soufflet 24. Le sachet reprend alors une géométrie proche de celle illustrée sur la figure 1. Il convient alors d'ouvrir l'élément 50, comme illustré sur la figure 3 pour accéder aisément au contenu C, par exemple un ensemble de couches pour bébés, du sachet, même si celui-ci est placé sous pression dans un sachet 10 initialement étanche. La présente invention permet en particulier de faciliter l'accès à des changes pour bébés. On a représenté sur les figures 4 et 5 une variante de réalisation dans laquelle le sachet comporte deux soufflets 24 et 28 repliés sur des faces diamétralement opposées du sachet, à savoir respectivement une partie de fond 20 et la partie d'embouchure 21. Bien entendu il est nécessaire dans ce cas de prévoir des moyens de maintien 30, 32, similaires à ceux précédemment décrits, associés au soufflet 28 formé sur l'embouchure. La présente invention présente par ailleurs l'avantage de rigidifier les extrémités des sachets ou sacs 10, notamment au niveau du fond. En effet comme on le voit sur les figures 2 et 5, le fond du sachet comprend trois épaisseurs 25, 26, 27. Il en est de même pour l'embouchure lorsque le sachet comporte deux soufflets. Ceci est extrêmement intéressant pour le positionnement en rayonnage en magasin. 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. Lors de la fermeture du sachet, le curseur 60 peut être placé au niveau du soufflet comme illustré sur les figures 2 et 5 ou hors soufflet, comme illustré sur la figure 7. Dans le cadre de la présente invention, les moyens de liaison amovible 30, 32, et l'élément de fermeture 50 peuvent être venus de matière sur le film composant la paroi de sachet, lors de la fabrication de ce film, ou encore être formés initialement d'éléments séparés rapportés, par exemple par soudure, sur le film composant le sachet. Selon les modes de réalisation précédemment décrits, les soufflets 24 et 28, respectivement prévus au niveau du fond 14 et de l'embouchure 12, s'étendent dans un plan globalement perpendiculaire à la direction d'introduction du contenu dans le sachet 10, par l'embouchure 12. Selon les variantes illustrées sur les figures 7 et 8, au contraire, les soufflets 24 et 28 s'étendent dans un plan globalement parallèle à la direction d'introduction du contenu dans le sachet 10 par l'embouchure 12. A cette fin, selon les figures 7 et 8, les soufflets 24 et 28 sont repliés sur eux-mêmes contre l'une des faces entourant l'embouchure d'ouverture 12. Comme on le voit sur la figure 7, selon une variante de l'invention chaque soufflet 24 ou 28 peut couvrir une partie seulement de la surface de la paroi du corps de sachet 10 contre laquelle lesdits soufflets 24 et 28 sont repliés. Cette variante dans laquelle les soufflets 24 et 28 ne couvrent qu'une partie de la section du sachet peut s'appliquer à l'ensemble des modes de réalisation de l'invention. 12 and closed at the mouth 12 by any suitable conventional means. In use, to allow access to the contents of the bag, it is sufficient to break the connecting element 30, 32 to deploy the bellows 24. The bag then resumes a geometry similar to that illustrated in FIG. it is then necessary to open the element 50, as shown in Figure 3 to easily access the content C, for example a set of baby diapers, the bag, even if it is placed under pressure in a bag 10 initially sealed . The present invention makes it possible in particular to facilitate access to baby diapers. FIGS. 4 and 5 show an alternative embodiment in which the bag comprises two bellows 24 and 28 folded on diametrically opposite sides of the bag, namely respectively a bottom portion 20 and the mouth portion 21. Of course it is necessary in this case to provide holding means 30, 32, similar to those described above, associated with the bellows 28 formed on the mouth. The present invention also has the advantage of stiffening the ends of the bags or bags 10, especially at the bottom. Indeed, as can be seen in Figures 2 and 5, the bottom of the bag comprises three thicknesses 25, 26, 27. It is the same for the mouth when the bag has two bellows. This is extremely interesting for shelf positioning in the store. 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. When closing the bag, the slider 60 can be placed at the bellows as shown in Figures 2 and 5 or without bellows, as shown in Figure 7. In the context of the present invention, the removable connection means 30 32, and the closure element 50 can be made of material on the film constituting the bag wall, during the manufacture of this film, or else be initially formed of separate elements reported, for example by welding, on the film composing the bag. According to the embodiments previously described, the bellows 24 and 28, respectively provided at the bottom 14 and the mouth 12, extend in a plane generally perpendicular to the direction of introduction of the contents into the bag 10, by the mouth 12. According to the variants illustrated in Figures 7 and 8, instead, the bellows 24 and 28 extend in a plane generally parallel to the direction of introduction of the contents into the bag 10 by the mouth 12. For this purpose, according to FIGS. 7 and 8, the bellows 24 and 28 are folded on themselves against one of the faces surrounding the opening mouth 12. As can be seen in FIG. 7, according to a variant of FIG. the invention each bellows 24 or 28 may cover only a portion of the surface of the wall of the bag body 10 against which said bellows 24 and 28 are folded. This variant in which the bellows 24 and 28 cover only a portion of the section of the bag can be applied to all embodiments of the invention.
