Description

La présente invention concerne le domaine des sachets comprenant des moyens de fermeture/ouverture multiples, en particulier à base de profilés complémentaires.The present invention relates to the field of bags comprising multiple closing / opening means, in particular based on complementary profiles.

De nombreux sachets de ce type ont déjà été proposés à des fins d'utilisation dans les domaines les plus divers.Many bags of this type have already been proposed for use in a wide variety of fields.

Les documents EP-1405798 , WO2005/120981 , FR-2792812 décrivent des dispositifs à base de fermeture à voiles multiples fixées sur un film commun de part et d'autre de profilés de fermeture.The documents EP-1405798 , WO2005 / 120981 , FR-2792812 describe devices based on a multiple-film closure fixed on a common film on both sides of closure profiles.

Le document EP-1457428 décrit un sachet dans lequel le moyen de fermeture comprend deux profilés de fermeture complémentaires portés par des voiles support respectifs. L'un de ces voiles est fixé en une première zone sur un film puis retourné sur lui-même pour être fixé en une seconde zone sur le second voile support et enfin est fixé sur une troisième zone sur le film support. La première zone de fixation et la troisième zone de fixation sont disposées de part et d'autre des profilés de fermeture. Un tel dispositif présente en théorie des intérêts. Cependant en pratique, un tel dispositif est très difficile à industrialiser en raison de la fixation requise entre les deux voiles support au niveau de la deuxième zone de fixation intermédiaire entre la première et la troisième zone de fixation.The document EP-1457428 describes a bag in which the closure means comprises two complementary closure profiles carried by respective support webs. One of these sails is fixed in a first zone on a film and then returned to itself to be fixed in a second zone on the second support sail and finally is fixed on a third zone on the support film. The first fixing zone and the third fixing zone are arranged on either side of the closure profiles. Such a device theoretically has interests. However, in practice, such a device is very difficult to industrialize because of the fixing required between the two support webs at the second intermediate attachment zone between the first and the third attachment zone.

Cependant, malgré de nombreuses tentatives et propositions faites à cet égard, jusqu'à ce jour, nombre de sachets ne présentent pas une étanchéité satisfaisante au niveau des moyens de fermeture/ouverture multiples prévus au niveau de l'embouchure des sachets.However, despite many attempts and proposals made in this regard, so far, many bags do not have a satisfactory seal at the multiple closing / opening means provided at the mouth of the bags.

La présente invention a maintenant pour objectif de proposer de nouveaux sachets qui permettent de remédier aux inconvénients de la technique antérieure.It is now an object of the present invention to provide novel pouches which overcome the disadvantages of the prior art.

Ce but est atteint dans le cadre de la présente invention grâce à un sachet d'emballage comprenant un moyen de fermeture/ouverture multiples fixé sur un film, le moyen de fermeture/ouverture multiples comprenant deux profilés de fermeture complémentaires fixés sur des voiles supports respectifs, caractérisé par le fait que l'un de ces voiles support est un voile large retourné sur lui-même et sur le moyen de fermeture/ouverture multiples pour chevaucher la totalité du moyen de fermeture, et fixé en deux zones distinctes sur le film de part et d'autre du moyen de fermeture/ouverture multiples.This object is achieved in the context of the present invention by means of a packaging bag comprising a multiple closing / opening means fixed to a film, the multiple closing / opening means comprising two profiles of complementary closure fixed on respective support webs, characterized by the fact that one of these support webs is a wide web returned on itself and on the multiple closing / opening means for overlapping the entire closure means, and fixed in two distinct areas on the film on either side of the multiple closing / opening means.

L'invention concerne également les moyens de fermeture/ouverture multiple pour la réalisation des sachets d'emballage précités.The invention also relates to multiple closing / opening means for producing the aforementioned packaging bags.

L'invention concerne par ailleurs un procédé de fabrication de sachets d'emballage comprenant les étapes qui consistent à i) fournir un moyen de fermeture/ouverture multiples comprenant deux profilés de fermeture complémentaires fixés sur des voiles support respectifs, ii) retourner, l'un de ces voiles support, formé d'un voile large, sur lui-même et sur le moyen de fermeture/ouverture multiples afin de chevaucher la totalité du moyen de fermeture, et iii) fixer, ce voile support large, en deux zones distinctes sur un film, de part et d'autre du moyen de fermeture/ouverture multiples.The invention also relates to a method of manufacturing packaging bags comprising the steps of i) providing a multiple closure / opening means comprising two complementary closure profiles fixed on respective support webs, ii) return, the one of these support webs, formed of a wide web, on itself and on the multiple closing / opening means in order to overlap the totality of the closure means, and iii) securing, this wide web, in two distinct zones on a film, on both sides of the multiple closing / opening means.

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

  • la figure 1 représente une vue schématique en coupe d'un sachet conforme à un premier mode de réalisation de la présente invention,
  • la figure 2 représente une vue similaire en coupe partielle d'une autre variante de sachet conforme 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 is a schematic sectional view of a bag according to a first embodiment of the present invention,
  • the figure 2 is a similar view in partial section of another alternative pouch according to the present invention.

Les sachets conformes à la présente invention comprennent essentiellement un corps de sachet 10 partiellement représenté sur les figures annexées et un moyen de fermeture/ouverture multiples 20 fixé sur le corps de sachet au niveau de l'embouchure de celui-ci.The pouches according to the present invention essentially comprise a bag body 10 partially shown in the accompanying figures and a multiple closure / opening means 20 fixed to the bag body at the mouth thereof.

Le corps de sachet 10 et le moyen de fermeture/ouverture multiples 20 peuvent faire l'objet en eux-mêmes de nombreuses variantes de réalisation.The bag body 10 and the multiple closure / opening means 20 can be subject in themselves many variants.

Le corps de sachet 10 est formé à base d'un film 12 composant deux feuillets principaux 14, 16 parallèles entre eux.The bag body 10 is formed based on a film 12 comprising two main sheets 14, 16 parallel to each other.

Les deux feuillets principaux 14, 16 peuvent être formés à partir d'un film 12 unique de forme tubulaire fermé à ses extrémités, ou encore un film replié sur lui-même pour former les deux feuillets principaux 14, 16 précités, reliés entre eux sur trois côtés.The two main sheets 14, 16 may be formed from a single film 12 of tubular shape closed at its ends, or a film folded on itself to form the two main sheets 14, 16 mentioned above, connected together on three sides.

Selon encore une autre variante, les deux feuillets principaux 14, 16 peuvent être formés à partir de tronçons de films respectifs initialement indépendants, reliés entre eux par collage ou soudure sur quatre côtés.According to yet another variant, the two main sheets 14, 16 may be formed from sections of respective films initially independent, interconnected by bonding or welding on four sides.

Le film 10 peut être réalisé en tous matériaux connus appropriés. Il est réalisé de préférence en matériau thermo-plastique, polyéthylène voire polypropylène, par exemple.The film 10 may be made of any suitable known material. It is preferably made of thermoplastic material, polyethylene or polypropylene, for example.

Cependant l'invention n'est pas limitée à cette disposition particulière. Elle englobe tous types de matériaux, y compris tous matériaux composites.However, the invention is not limited to this particular provision. It encompasses all types of materials, including all composite materials.

Le moyen de fermeture/ouverture multiples 20 peut également faire l'objet de nombreuses variantes de réalisation.The multiple closing / opening means 20 can also be the subject of numerous alternative embodiments.

De préférence, le moyen de fermeture/ouverture multiples 20 comprend deux voiles support 22, 24 supportant respectivement un élément de fermeture 23, 25 tel qu'un élément mâle et un élément femelle complémentaires comme illustré sur la figure 1 et sur la figure 3 ou encore toute structure équivalente, par exemple à base de crochets comme illustré sur la figure 2.Preferably, the multiple closure / opening means 20 comprises two supporting webs 22, 24 respectively supporting a closure element 23, 25 such as a complementary male element and a female element as illustrated in FIG. figure 1 and in FIG. 3 or any equivalent structure, for example based on hooks as illustrated in FIG. figure 2 .

Par ailleurs, de préférence, le moyen de fermeture/ouverture multiples 20 est équipé d'un curseur 30.Furthermore, preferably, the multiple closing / opening means 20 is equipped with a slider 30.

La fonction connue d'un tel curseur est de faciliter l'ouverture et la fermeture des moyens 20 par l'utilisateur.The known function of such a cursor is to facilitate the opening and closing of the means 20 by the user.

De nombreuses structures de curseur 30 sont connues de l'homme de l'art et sont compatibles avec la présente invention.Many cursor structures are known to those skilled in the art and are compatible with the present invention.

On rappelle que, le plus souvent, le curseur 30 est formé d'une embase munie de deux flancs latéraux et d'un muret central. Le muret définit en combinaison avec les flancs latéraux deux canaux non parallèles qui reçoivent respectivement l'un des profilés de fermeture 23, 25.It is recalled that, most often, the slider 30 is formed of a base provided with two lateral flanks and a central wall. The wall defines in combination with the lateral flanks two non-parallel channels which respectively receive one of the closing profiles 23, 25.

Lorsque le curseur 30 est déplacé dans un premier sens donné, le curseur tend à rapprocher et mettre en prise les profilés de fermeture pour fermer le sachet. Au contraire, lorsque le curseur est déplacé dans le second sens opposé, il tend à séparer les profilés de fermeture 23, 25 et par conséquent à ouvrir le sachet.When the slider 30 is moved in a first direction, the slider tends to approximate and engage the closure bars to close the bag. On the contrary, when the slider is moved in the second opposite direction, it tends to separate the closure profiles 23, 25 and consequently to open the bag.

La composition et la structure du corps de sachet 10, des moyens de fermeture/ouverture 20 et du curseur 30 sont connues en soi de l'homme de l'art et ne seront donc pas décrites plus en détails par la suite.The composition and structure of the bag body 10, closing / opening means 20 and slider 30 are known per se to those skilled in the art and will therefore not be described in more detail later.

Selon la présente invention, comme indiqué précédemment, l'un des voiles support 22,24 est un voile large, retourné sur lui-même et sur le moyen de fermeture/ouverture multiples 20 pour chevaucher la totalité du moyen de fermeture et fixé en deux zones distinctes 40, 42 sur le film 10, de part et d'autre du moyen de fermeture/ouverture multiples 20.According to the present invention, as indicated above, one of the support webs 22, 24 is a wide web, turned over on itself and on the multiple closing / opening means 20 to overlap the entire closure means and fastened in half. distinct zones 40, 42 on the film 10, on either side of the multiple closing / opening means 20.

Sur les figures annexées, les points de soudure sont illustrés de manière schématique sous forme d'un « X ».In the accompanying figures, the weld points are schematically illustrated in the form of an "X".

La présente invention peut faire l'objet de diverses variantes de réalisation.The present invention may be the subject of various embodiments.

On a représenté sur la figure 1 une première variante de réalisation suivant laquelle le voile 22 est fixé tout d'abord, à proximité du profilé 23, dans une zone référencée 40 sur la face interne du film 12, puis est retourné sur lui-même pour chevaucher la totalité du moyen de fermeture 20, fixé au niveau d'une seconde zone 42 sur le film 12, et retourné à nouveau sur lui-même pour être fixé au niveau d'une troisième zone 43 sur l'extrémité du second voile support 24, moins large.We have shown on the figure 1 a first variant embodiment in which the web 22 is fixed firstly, close to the section 23, in a zone referenced 40 on the inner face of the film 12, then is returned to itself to overlap the entire means of closure 20, fixed at a second zone 42 on the film 12, and returned again on itself to be fixed at a third zone 43 on the end of the second support web 24, less wide.

Les deux zones 40, 42 de soudure du voile 22 sur le film 10 sont opposées par rapport au moyen de fermeture 20, c'est-à-dire situées de part et d'autre, respectivement de celui-ci.The two zones 40, 42 of welding of the web 22 on the film 10 are opposed relative to the closing means 20, that is to say located on either side, respectively thereof.

Le cas échéant, le film 10 peut comporter une zone de pré-découpe ou faiblesse, référencée schématiquement 18, entre les deux zones de soudure 40, 42.Where appropriate, the film 10 may comprise a pre-cut or weakness zone, referenced schematically 18, between the two soldering zones 40, 42.

L'homme du métier comprendra que la rupture de cette zone 18 permet à un utilisateur d'accéder au moyen de fermeture 20 et ce faisant, au contenu du sachet.Those skilled in the art will understand that the breaking of this zone 18 allows a user to access the closure means 20 and thereby the contents of the bag.

Pour ce faire, le cas échéant, le voile support 22 peut présenter lui-même une zone de faiblesse ou pré-rupture 28 dans son tronçon situé entre les deux zones de soudure 40 et 42.To do this, if necessary, the support web 22 may itself have a zone of weakness or pre-rupture 28 in its section located between the two welding zones 40 and 42.

L'homme du métier comprendra que le voile 22 chevauchant le moyen de fermeture sert à la fois de témoin d'ouverture et de moyen d'étanchéité.Those skilled in the art will understand that the web 22 overlapping the closure means serves both as an opening control and a sealing means.

Il sert de témoin d'ouverture en ce sens que sa rupture est nécessaire pour permettre à un utilisateur d'accéder au contenu du sachet.It serves as an opening witness in that its break is necessary to allow a user to access the contents of the bag.

Tant que le voile 22 n'est pas rompu, l'utilisateur sait que le sachet n'a pas été ouvert. Au contraire, à la première ouverture pour accéder au contenu du sachet, le voile 22 doit impérativement être rompu.As the veil 22 is not broken, the user knows that the bag has not been opened. On the contrary, at the first opening to access the contents of the bag, the veil 22 must imperatively be broken.

Il sert de moyen d'étanchéité en ce sens que, avant rupture, grâce à ses deux zones de fixation 40, 42 de part et d'autre du moyen de fermeture 20, il assure une parfaite étanchéité entre ces deux zones, quand bien même le curseur 30 séparant partiellement les profilés de fermeture 23, 25 assurerait une rupture d'étanchéité à ce niveau.It serves as a sealing means in that, before breaking, thanks to its two attachment zones 40, 42 on either side of the closure means 20, it ensures a perfect seal between these two zones, even though the slider 30 partially separating the closure profiles 23, 25 would provide a seal break at this level.

On a représenté sur la figure 2 annexée une autre variante de réalisation selon laquelle les deux voiles support 22, 24 sont venus de matière et constituent ainsi un ensemble en « U ».We have shown on the figure 2 appended another embodiment according to which the two support webs 22, 24 are integral and thus constitute a set of "U".

Dans ce cas, le voile support 22 est fixé en 40 et 42, conformément au premier mode de la réalisation, sur le film 12, de part et d'autre du moyen de fermeture 20.In this case, the support web 22 is fixed at 40 and 42, according to the first embodiment, on the film 12, on either side of the closure means 20.

Dans ce cas, une soudure équivalente à celle référencée 43 sur la figure 1 n'est plus nécessaire.In this case, a weld equivalent to that referenced 43 on the figure 1 no longer necessary.

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.
