Description

La présente invention concerne un système d'ouverture/fermeture destiné notamment à des sacs d'emballage.The present invention relates to an opening / closing system intended in particular for packaging bags.

Il est connu par le document FR 2 833 576 d'utiliser des systèmes d'ouverture/fermeture de sac d'emballage comprenant une pièce de base plane délimitant au moins partiellement une ouverture à travers elle, cette pièce de base comportant des moyens de guidage coopérant avec des moyens de guidage d'un coulisseau permettant d'obturer l'ouverture ou de laisser libre celle-ci, la pièce de base plane étant destinée à être fixée à la paroi du sac de telle sorte que l'ouverture qu'elle délimite coïncide avec une ouverture aménagée dans la paroi du sac.He is known by the document FR 2 833 576 to use packaging bag opening / closing systems comprising a flat base part at least partially delimiting an opening therethrough, this base part comprising guiding means cooperating with guide means of a slider for closing the opening or to leave it free, the flat base piece being intended to be fixed to the wall of the bag so that the opening it delimits coincides with an opening in the wall of the bag. bag.

Ce type de système d'ouverture/fermeture peut notamment être fixé en regard d'une prédécoupe formant une bande détachable lors de la première utilisation, cette prédécoupe assurant ainsi l'inviolabilité du sac, un utilisateur pouvant identifier immédiatement si le sac a déjà été ouvert.This type of opening / closing system can in particular be fixed next to a precut forming a detachable strip at the first use, this precut thus ensuring the inviolability of the bag, a user can immediately identify if the bag has already been open.

Il apparaît toutefois que cette prédécoupe comprend des orifices qui ne garantissent pas une étanchéité satisfaisante. D'autre part, le système d'ouverture/fermeture lui-même laisse un passage non étanche au niveau de son ouverture.It appears, however, that this pre-cut includes orifices that do not guarantee a satisfactory seal. On the other hand, the opening / closing system itself leaves a leaky passage at its opening.

L'étanchéité du sac étant recherchée, pour des raisons de conservation de son contenu par exemple, il faut donc procéder à la mise en place d'un dispositif supplémentaire, comme un opercule collé ou soudé et pouvant être retiré. Toutefois, ce type de dispositif est situé à l'extérieur du sac et peut facilement être endommagé.Sealing of the bag being sought, for reasons of conservation of its content for example, it is necessary to proceed to the establishment of an additional device, such as a seal glued or welded and can be removed. However, this type of device is located outside the bag and can easily be damaged.

Il est connu également d'utiliser des dispositifs permettant de détruire la paroi du sac en elle-même, à un endroit ne comportant pas de zone de faiblesse. En particulier, on peut citer les documents US 5 167 608 , US 6 652 436 , US 6 273 607 , EP 0 485 741 .It is also known to use devices for destroying the wall of the bag itself, in a place with no area of weakness. In particular, we can mention the documents US 5,167,608 , US 6,652,436 , US 6,273,607 , EP 0 485 741 .

Dans les dispositifs décrits dans les documents cités ci-dessus, la découpe se révèle difficile car la paroi se situe en retrait par rapport à l'ouverture du dispositif dans laquelle passe l'organe de découpe. D'autre part, la paroi du sac doit assurer la tenue de celui-ci est donc résistante à cette découpe.In the devices described in the documents cited above, the cutting is difficult because the wall is set back relative to the opening of the device through which the cutting member. On the other hand, the wall of the bag must ensure the holding thereof is resistant to this cut.

En conséquence, la présente invention a pour but de fournir un système d'ouverture/fermeture dont l'étanchéité est améliorée, en ne rajoutant pas de dispositif extérieur supplémentaire sur le sac et en conservant la simplicité d'utilisation et de fabrication de celui-ci.Accordingly, the present invention aims to provide an opening / closing system whose sealing is improved, by not adding additional external device on the bag and retaining the simplicity of use and manufacture of it. this.

A cet effet, la présente invention a pour objet un système d'ouverture/fermeture, notamment pour sacs d'emballage, comportant une pièce de base plane délimitant au moins partiellement une ouverture à travers elle, cette pièce de base comportant des moyens de guidage parallèlement à l'ouverture coopérant avec des moyens de guidage d'un coulisseau destiné à obturer ou à laisser libre l'ouverture, caractérisé en ce que l'ouverture, avant la première utilisation, est obturée au moins partiellement par une couche de matière, et en ce que le coulisseau comporte un curseur orienté vers l'ouverture permettant de détruire au moins partiellement la couche de matière pour libérer l'ouverture lors du premier déplacement du coulisseau.For this purpose, the subject of the present invention is an opening / closing system, in particular for packaging bags, comprising a flat base part at least partially delimiting an opening therethrough, this base part comprising guiding means. parallel to the opening cooperating with means for guiding a slide intended to close off or to leave the opening open, characterized in that the opening, before the first use, is closed at least partially by a layer of material, and in that the slider comprises a slider oriented towards the opening making it possible to at least partially destroy the layer of material to release the opening during the first displacement of the slider.

Ces dispositions permettent d'atteindre le but évoqué ci-dessus. La couche de matière peut être de résistance déterminée pour une découpe aisée, sans avoir à assurer la tenue du sac. Cette couche de matière est située directement dans l'ouverture, assurant une position optimale pour la découpe.These provisions serve to achieve the purpose mentioned above. The layer of material may be of determined strength for easy cutting, without having to ensure the holding of the bag. This layer of material is located directly in the opening, ensuring an optimal position for cutting.

Avantageusement, la couche de matière est venue de moulage avec la pièce de base.Advantageously, the layer of material is molded with the base piece.

Selon un mode de réalisation, la couche de matière présente une zone de faiblesse ou son épaisseur est plus faible.According to one embodiment, the layer of material has a zone of weakness or its thickness is smaller.

Avantageusement, la zone de faiblesse est ménagée sur sensiblement toute la longueur de l'ouverture.Advantageously, the zone of weakness is formed over substantially the entire length of the opening.

Selon un mode de réalisation, un logement pour le curseur est ménagé dans la couche de matière, les dimensions de ce logement étant légèrement inférieures aux dimensions du curseur, celui-ci étant monté en force dans le logement.According to one embodiment, a housing for the cursor is formed in the layer of material, the dimensions of this housing being slightly smaller than the dimensions of the slider, the latter being mounted in force in the housing.

Avantageusement, le logement est situé à l'une des extrémités de l'ouverture, et le curseur est disposé en regard de ce logement dans la position fermée du curseur.Advantageously, the housing is located at one end of the opening, and the cursor is disposed opposite this housing in the closed position of the cursor.

La présente invention a également pour objet un sac d'emballage équipé sur au moins une de ses parois d'un système d'ouverture/fermeture décrit ci-dessus.The present invention also relates to a packaging bag equipped on at least one of its walls with an opening / closing system described above.

Avantageusement, le système d'ouverture/fermeture est fixé sur la face interne d'une paroi du sac par la pièce de base plane, le coulisseau étant situé du coté de la base plane orientée vers la paroi, le système étant disposé en face d'une pré découpe réalisée dans la paroi.Advantageously, the opening / closing system is fixed on the internal face of a wall of the bag by the flat base piece, the slide being located on the side of the flat base facing the wall, the system being disposed opposite a pre-cut made in the wall.

La présente invention a également pour objet un film destiné à former les paroi d'un sac d'emballage, ledit film comportant au moins un système d'ouverture/fermeture.The present invention also relates to a film intended to form the walls of a packaging bag, said film comprising at least one opening / closing system.

Avantageusement, ce film est conditionné sous forme de bobine.Advantageously, this film is packaged in the form of a coil.

La présente invention sera mieux comprise à la lecture de la description suivante, en référence au dessin annexé représentant un mode de réalisation d'un dispositif d'ouverture/fermeture selon l'invention.

  • La figure 1 est une vue partielle d'un sac sur lequel est fixé un système d'ouverture/fermeture selon l'invention.

  • La figure 4 est une vue en coupe selon IV-IV de figure 3.
  • La figure 5 est une vue en coupe selon V-V de figure 3.
  • La figure 6 est une vue similaire à figure 5, le système étant représenté au cours de la première ouverture.
The present invention will be better understood on reading the following description, with reference to the appended drawing showing an embodiment of an opening / closing device according to the invention.
  • Figure 1 is a partial view of a bag on which is fixed an opening / closing system according to the invention.
  • Figure 2 is a partial exploded perspective view of an opening / closing system according to the invention, in partial section.
  • Figure 3 is a top view of the system of Figure 2.
  • FIG. 4 is a sectional view on IV-IV of FIG.
  • Figure 5 is a sectional view along VV of Figure 3.
  • Figure 6 is a view similar to Figure 5, the system being shown during the first opening.

La figure 1 montre un sac 2 qui comporte deux parois 3 fixées l'une à l'autre, l'une de ces parois 3 comportant un système d'ouverture/fermeture 4 fixé sur la face interne d'une ouverture 5 de cette paroi 3.FIG. 1 shows a bag 2 which has two walls 3 fixed to one another, one of these walls 3 comprising an opening / closing system 4 fixed on the internal face of an opening 5 of this wall 3.

Ce système d'ouverture/fermeture 4 peut être, comme décrit dans le document FR 2 833 576 , fixé en regard d'une prédécoupe délimitant une bande possédant des extrémités arrondies, qui sont découpées et qui peuvent ainsi être soulevées et saisies pour permettre le retrait de cette bande par traction manuelle, le retrait de cette bande délimitant ainsi l'ouverture 5 dans la paroi 3 du sac 2.This opening / closing system 4 can be, as described in the document FR 2 833 576 fixed against a precut defining a strip having rounded ends, which are cut and which can thus be raised and seized to allow the withdrawal of this band by manual pulling, the withdrawal of this band thus delimiting the opening 5 in the wall 3 of the bag 2.

Un utilisateur peut donc, lors de la première utilisation, enlever la bande par traction manuelle, puis ouvrir et refermer le sac en utilisant le système d'ouverture/fermeture 4.A user can therefore, during the first use, remove the band by manual pull, then open and close the bag using the opening / closing system 4.

Comme le montre plus particulièrement la figure 1, le système d'ouverture/fermeture 4 comprend une pièce de base 7 plane délimitant au moins partiellement une ouverture 8 à travers elle, cette pièce de base 7 comportant des moyens de guidage 10 parallèlement à l'ouverture coopérant avec des moyens de guidage 12 d'un coulisseau 9 permettant de d'obturer ou de laisser libre l'ouverture 8.As shown more particularly in Figure 1, the opening / closing system 4 comprises a flat base part 7 at least partially delimiting an opening 8 through it, this base part 7 having guide means 10 parallel to the opening cooperating with guide means 12 of a slider 9 making it possible to seal or leave free the opening 8.

L'ouverture 8, avant la première utilisation, est obturée par une couche de matière 13 venue de moulage avec la pièce de base 7, comme cela est illustré sur les figure 2 à 6.The opening 8, before the first use, is closed by a layer of material 13 integrally molded with the base part 7, as illustrated in FIGS. 2 to 6.

Le coulisseau 9 comporte un curseur 14 orienté vers l'ouverture 8 permettant de détruire au moins partiellement la couche de matière 13 pour libérer l'ouverture 8.The slider 9 comprises a slider 14 oriented towards the opening 8 making it possible to destroy at least partially the layer of material 13 to release the opening 8.

Un logement 15 pour le curseur 14 est ménagé dans la couche de matière 13, les dimensions de ce logement 15 étant légèrement inférieures au dimensions du curseur 14, celui-ci étant monté en force dans le logement.A housing 15 for the slider 14 is formed in the layer of material 13, the dimensions of this housing 15 being slightly smaller than the dimensions of the slider 14, the latter being mounted in force in the housing.

Le curseur est situé à une extrémité du coulisseau lorsque celui-ci est en position de fermeture de l'ouverture 8, et le logement 15 est situé également à une extrémité de l'ouverture 8.The slider is located at one end of the slide when it is in the closed position of the opening 8, and the housing 15 is also located at one end of the opening 8.

Afin de faciliter la destruction de la couche de matière 13 par le curseur 14, la couche de matière présente une zone de faiblesse 16 où son épaisseur est plus faible.In order to facilitate the destruction of the layer of material 13 by the slider 14, the layer of material has a zone of weakness 16 where its thickness is lower.

Cette zone de faiblesse 16 s'étend sur sensiblement toute la longueur de l'ouverture 8.This zone of weakness 16 extends over substantially the entire length of the opening 8.

Avantageusement, le curseur 14 permet également de venir en butée contre l'extrémité 17 de l'ouverture 8 opposée à celle comportant le logement 15, afin de limiter la course du curseur 14.Advantageously, the slider 14 also makes it possible to abut against the end 17 of the opening 8 opposite that with the housing 15, in order to limit the stroke of the slider 14.

La couche de matière 13 permet d'assurer l'étanchéité de l'ouverture 8. Le logement 15 est de dimensions inférieures au curseur 14, la mise en place en force de ce curseur garantissant également l'étanchéité au niveau du logement, qui peut ainsi être traversant.The layer of material 13 makes it possible to seal the opening 8. The housing 15 is of smaller dimensions than the slider 14, the positioning in force of this slider also ensuring the seal at the housing, which can to be through.

Le curseur 14, dans ce mode d'exécution, présente une forme parallélépipédique qui permet une réalisation simple et permet un contact efficace contre les parois du logement 15 pour assurer une bonne étanchéité. D'autres formes de ce curseur peuvent être utilisées en variante, notamment des formes en biseau favorisant la destruction de la couche de matière 13. La forme du logement 15 est dans ce cas adaptée pour présenter une forme complémentaire.The slider 14, in this embodiment, has a parallelepiped shape that allows a simple embodiment and allows effective contact against the walls of the housing 15 to ensure a good seal. Other forms of this slider can be used alternatively, including beveled shapes promoting the destruction of the material layer 13. The shape of the housing 15 is in this case adapted to have a complementary shape.

Dans le mode de réalisation présenté, le coulisseau comporte à chacune de ses extrémités, une languette de préhension 18, facilitant la prise en main par un utilisateur.In the embodiment shown, the slide has at each of its ends, a gripping tab 18, facilitating the grip by a user.

Il est également possible de réaliser la couche de matière en la rapportant après la fabrication de la pièce de base. Toutefois, cette solution complique considérablement la fabrication et augmente le coût de cette pièce.It is also possible to make the layer of material by bringing it back after the manufacture of the base piece. However, this solution considerably complicates the manufacture and increases the cost of this piece.

La figure 6 permet d'illustrer la destruction de la couche de matière 13 lors de la première ouverture du système 4.FIG. 6 illustrates the destruction of the layer of material 13 during the first opening of the system 4.

Il est avantageux d'équiper le film destiné à former les parois d'un sac d'emballage avec des systèmes d'ouvertures 4 décrits ci-dessus avant de conformer les sacs 3. En particulier, ce film peut être conditionné sous forme de bobines qui sont ensuite utilisable sur des machines connues de fabrication de sacs.It is advantageous to equip the film intended to form the walls of a packaging bag with the opening systems 4 described above before forming the bags 3. In particular, this film can be packaged in the form of coils. which are then usable on known bag making machines.

Comme il va se soi, l'invention ne se limite pas aux formes de réalisation préférentielle décrite ci-dessus, à titre d'exemple non limitatif ; elle en embrasse au contraire toutes les variantes de réalisation dans le cadre des revendications ci-après.As is self-evident, the invention is not limited to the preferred embodiments described above, by way of non-limiting example; on the contrary, it embraces all the variants within the scope of the following claims.
