Description

SYSTEME DOUVERTURE/FERMETURE ETANCHE DESTINE A DES SACS D'EMBALLAGESWATERPROOFING / CLOSING SYSTEM FOR PACKAGING BAGS
La présente invention concerne un système d 'ouverture/fermeture destiné notamment à des sacs d'emballage. 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. 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. 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. 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. 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 e faiblesse. En particulier, on peut citer les documents US 5 167 608, US 6 S 52 436, US 6 273 607, EP 0485 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 d écoupe. 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. A cet effet, la présente invention a pour objet un système d'ouverture/fermeture, notamment pour sacs d'emballage, du type 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 u n 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. Ces dispositions permettent d'atteindre le but évoojué 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. Avantageusement, la couche de matière est venue de moulage avec la pièce de base. Selon un mode de réalisation, la couche de matière présente une zone de faiblesse ou son épaisseur est plus faible. Avantageusement, la zone de faiblesse est ménagée sur sensiblement toute la longueur de l'ouverture. Selon un mode de réalisation, un logement pou r 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. 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. La présente invention a également pour objet un -sac d'emballage équipé sur au moins une de ses parois d'un système
Figure imgf000004_0001
décrit ci-dessus. 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. La présente invention a également pour objet un film destin é à former les paroi d'un sac d'emballage comportant au moins un système d'ouverture/fermeture. Avantageusement, ce film est conditionné sous forme de bobine*. 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 2 est une en perspective éclatée partielle d'un système d'ouverture/fermeture selon l'invention, en coupe partielle. La figure 3 est une vue de dessus du système de figure 2. 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. 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. Ce système d'ouverture/fermeture 4 peut être, comme décrit d-ans 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 dan -s la paroi 3 du sac 2. Un utilisateur peut donc, lors de la première utilisation, enlevé r la bande par traction manuelle, puis ouvrir et refermer le sac en utilisant le système d'ouverture/fermeture 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. L'ouverture 8, avant la première utilisation, est obturée par un« couche de matière 13 venue de moulage avec la pièce de base 7, comme cel-a est illustré sur les figure 2 à 6. Le coulisseau 9 comporte un curseur 14 orienté vers l'ouverture S permettant de détruire au moins partiellement la couche de matière 13 pour libérer l'ouverture 8. Un logement 15 pour le curseur 14 est ménagé dans la couche d«e 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. 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. 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. Cette zone de faiblesse 16 s'étend sur sensiblement toute la longueur de l'ouverture 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. 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. Le curseur 14, dans ce mode d'exécution, présente une forme paràllélepipédique 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, notammen t 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. 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. 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. La figure 6 permet d'illustrer la destruction de la couche de matière 13 lors de la première ouverture du système 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. 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. The present invention relates to an opening / closing system intended in particular for packaging bags. It is known from document FR 2 833 576 to use systems for opening / closing a packaging bag comprising a flat base part at least partially delimiting an opening through it, this base part comprising guide means cooperating with means for guiding a slide making it possible to close the opening or to leave it free, the flat base part 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. This type of opening / closing system can in particular be fixed opposite a pre-cut forming a detachable strip during the first use, this pre-cut thus ensuring the inviolability of the bag, a user being able to immediately identify if the bag has already been open. However, it appears that this precut includes orifices which do not guarantee satisfactory sealing. On the other hand, the opening / closing system itself leaves a leaky passage at its opening. The tightness of the bag being sought, for reasons of conservation of its content for example, it is therefore necessary to install an additional device, such as a glued or welded seal which can be removed. However, this type of device is located on the outside of the bag and can easily be damaged. It is also known to use devices making it possible to destroy the wall of the bag itself, at a place having no zone of weakness. In particular, we can cite the documents US 5,167,608, US 6 S 52,436, US 6,273,607, EP 0485 741. In the devices described in the documents cited above, the cutting turns out to be difficult because the wall is located set back from the opening of the device through which the cutting member passes. On the other hand, the wall of the bag must ensure that it is held is therefore resistant to this cutting. Consequently, the object of the present invention is to provide an opening / closing system whose sealing is improved, by not adding any additional external device to the bag and by retaining the simplicity of use and manufacture of the latter. this. To this end, the subject of the present invention is an opening / closing system, in particular for packaging bags, of the type comprising a flat base part at least partially delimiting an opening through it, this base part comprising means guide parallel to the opening cooperating with means for guiding a slide intended to close or leave free the opening, characterized in that the opening, before the first use, is closed at least partially by a layer of material, and in that the slide comprises a cursor oriented towards the opening making it possible to at least partially destroy the layer of material to release the opening during the first movement of the slide. These provisions make it possible to achieve the above objective. The layer of material can 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. Advantageously, the layer of material has come from molding with the base part. According to one embodiment, the layer of material has a zone of weakness or its thickness is thinner. Advantageously, the zone of weakness is formed over substantially the entire length of the opening. 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 cursor, the latter being forcibly mounted in the housing. Advantageously, the housing is located at one of the ends of the opening, and the slider is arranged opposite this housing in the closed position of the slider. The present invention also relates to a packaging bag equipped on at least one of its walls with a system
Figure imgf000004_0001
described above. Advantageously, the opening / closing system is fixed to the internal face of a wall of the bag by the flat base part, the slide being located on the side of the flat base oriented towards the wall, the system being arranged opposite a pre-cut made in the wall. The present invention also relates to a film intended to form the walls of a packaging bag comprising at least one opening / closing system. Advantageously, this film is packaged in the form of a reel *. The present invention will be better understood on reading the following description, with reference to the appended drawing representing 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. Figure 4 is a sectional view along IV-IV of Figure 3. 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. Figure 1 shows a bag 2 which has two walls 3 fixed to one another, one of these walls 3 having an opening / closing system 4 fixed on the internal face of an opening 5 of this wall 3. This opening / closing system 4 can be, as described in the document FR 2 833 576, fixed opposite a pre-cut delimiting a strip having rounded ends, which are cut and which can thus be lifted and seized to allow the removal of this strip by manual traction, the withdrawal of this strip thus delimiting the opening 5 dan -s the wall 3 of the bag 2. A user can therefore, during the first use, removed the strip by traction manual, then open and close the bag using the opening / closing system 4. As shown more particularly in FIG. 1, the opening / closing system 4 comprises a flat base part 7 at least partially defining an opening 8 through it, this te base part 7 comprising guide means 10 parallel to the opening cooperating with guide means 12 of a slide 9 making it possible to close or leave the opening 8 free. The opening 8, before the first use, is closed by a "layer of material 13 molded with the base part 7, as cel-a is illustrated in Figures 2 to 6. The slide 9 has a cursor 14 oriented towards the opening S making it possible to at least partially destroy the layer of material 13 to release the opening 8. A housing 15 for the cursor 14 is formed in the layer of material 13, the dimensions of this housing 15 being slightly smaller the dimensions of the slider 14, the latter being force-fitted into the housing. The cursor is located at one end of the slider when the latter is in the closed position of the opening 8, and the housing 15 is also located at one end of the opening 8. In order to facilitate the destruction of the layer of material 13 by the cursor 14, the material layer has a zone of weakness 16 where its thickness is thinner. This zone of weakness 16 extends over substantially the entire length of the opening 8. Advantageously, the slider 14 also makes it possible to come into abutment against the end 17 of the opening 8 opposite to that comprising the housing 15, in order to limit the travel of the cursor 14. The layer of material 13 makes it possible to seal the opening 8. The housing 15 is of dimensions smaller than the cursor 14, the positioning in force of this cursor also guaranteeing the seal at the level of the accommodation, which can thus be through. The cursor 14, in this embodiment, has a parallelepipedal shape which allows a simple production and allows effective contact against the walls of the housing 15 to ensure a good seal. Other forms of this cursor can be used as a variant, in particular bevel shapes favoring the destruction of the layer of material 13. The shape of the housing 15 is in this case adapted to have a complementary shape. In the embodiment presented, the slide comprises at each of its ends, a gripping tab 18, facilitating the handling by a user. It is also possible to produce the layer of material by bringing it back after the manufacture of the base part. However, this solution considerably complicates manufacturing and increases the cost of this part. FIG. 6 illustrates the destruction of the layer of material 13 when the system 4 is opened for the first time. It is advantageous to equip the film intended to form the walls of a packaging bag with opening systems. 4 described above before shaping the bags 3. In particular, this film can be packaged in the form of reels which can then be used on known bag making machines. As is obvious, the invention is not limited to the preferred embodiments described above, by way of nonlimiting example; on the contrary, it embraces all of the variant embodiments thereof within the scope of the claims below.
