Description

SACHET D’EMBALLAGE ET FILM BOBINE DONT LE CORPS DU SACHET EST ISSU  PACKAGING BAG AND COIL FILM HAVING THE BODY OF THE BAG
DOMAINE DE L’INVENTION L’invention concerne un sachet d’emballage et un film bobiné dont le corps du sachet est issu. FIELD OF THE INVENTION The invention relates to a packaging bag and a wound film whose bag body is issued.
Elle concerne plus particulièrement un sachet d’emballage comprenant un corps souple de délimitation d’une enceinte de stockage, ledit corps comprenant au moins deux faces en regard et deux soufflets reliant lesdites faces en regard entre elles, au moins une ouverture d’accès ménagée dans ledit corps au niveau de l’un des soufflets du corps, ladite ouverture d’accès étant apte à passer d’une position fermée à une position ouverte dans laquelle le sachet est apte à être vidangé par ladite ouverture d’accès, et un bec verseur rapporté sur la surface externe du corps du sachet, au niveau du soufflet du corps équipé de l’ouverture d’accès. It relates more particularly to a packaging bag comprising a flexible body delimiting a storage enclosure, said body comprising at least two opposite faces and two bellows connecting said faces facing each other, at least one access opening arranged in said body at one of the bellows of the body, said access opening being adapted to move from a closed position to an open position in which the bag is able to be emptied by said access opening, and a spout attached to the outer surface of the bag body, at the bellows of the body equipped with the access opening.
ART ANTÉRIEUR PRIOR ART
De tels sachets de stockage de produits en vrac vidangeables par déversement sont bien connus à ceux versés dans cet art. Such dumped bulk product storage bags are well known to those skilled in the art.
Jusqu’à présent, la conception du bec verseur sur de tels sachets est complexe, rendant difficile la pose du bec verseur sur le film constitutif du corps avant conformation du film par une ensacheuse. Until now, the design of the spout on such bags is complex, making it difficult to pose the pouring spout on the film constituting the body before shaping the film by a bagger.
En outre, à l’état posé du bec verseur sur le film, l’épaisseur du bec verseur rend critique le stockage du film à l’état bobiné avant conformation à l’aide d’une ensacheuse. Par ailleurs, généralement, l’ouverture du sachet pour une vidange par déversement nécessite un outil, tel qu’une paire de ciseaux, et la refermeture est généralement problématique, après quelques utilisations du bec verseur, en raison d’une rapide dégradation. In addition, in the installed state of the spout on the film, the thickness of the spout makes it critical to store the film in the wound state before shaping with a bagger. Furthermore, generally, the opening of the bag for a discharge by spillage requires a tool, such as a pair of scissors, and the reclosing is generally problematic, after a few uses of the spout, due to a rapid degradation.
De même, la refermeture nécessite souvent la présence d’un adhésif incompatible avec un remplissage du sachet en produits pulvérulents en raison de la neutralisation de la colle par le produit pulvérulent. Similarly, the reclosing often requires the presence of an adhesive incompatible with a filling of the bag of pulverulent products due to the neutralization of the glue by the powdery product.
Enfin, le déversement est généralement difficile à opérer, la visibilité du bec verseur étant mauvaise et le déploiement du bec verseur étant complexe à réaliser avec un ou deux doigts. Finally, the spill is generally difficult to operate, the visibility of the spout is poor and the deployment of the spout is complex to achieve with one or two fingers.
BUTS ET RÉSUMÉ Un but de la présente invention est donc de proposer un sachet d’emballage dont la conception permet de manière confortable de vidanger par déversement le sachet et de refermer aisément le sachet, y compris en présence de produits pulvérulents. OBJECTS AND SUMMARY An object of the present invention is therefore to provide a packaging bag whose design allows a comfortable way to empty the bag by pouring and to close the bag easily, including in the presence of powdery products.
Un autre but de l’invention est de proposer un sachet dont la conception permet de pouvoir procéder à plusieurs opérations de déversement sans nuire au fonctionnement du bec verseur et à la fermeture du sachet. Another object of the invention is to provide a bag whose design allows to perform several spill operations without affecting the operation of the spout and closing the bag.
À cet effet, l’invention a pour objet un sachet d’emballage comprenant un corps souple de délimitation d’une enceinte de stockage, ledit corps comprenant au moins deux faces en regard et deux soufflets reliant lesdites faces en regard entre elles, au moins une ouverture d’accès ménagée dans ledit corps au niveau de l’un des soufflets du corps, ladite ouverture d’accès étant apte à passer d’une position fermée à une position ouverte dans laquelle le sachet est apte à être vidangé par ladite ouverture d’accès et un bec verseur rapporté sur la surface externe du corps du sachet au niveau du soufflet du corps équipé de l’ouverture d’accès, caractérisé en ce que le bec verseur comprend une étiquette autocollante et un masque positionnable entre au moins une partie de l’étiquette autocollante et le corps du sachet, en ce que l’étiquette autocollante, qui est une étiquette au moins partiellement séparable du corps du sachet, est, au moins avant sa première séparation au moins partielle du corps du sachet, disposée sur le corps du sachet dans une position dans laquelle tout accès à l’ouverture d’accès est empêché, en ce que ledit masque, de rigidité, de préférence, supérieure à la rigidité du corps, affecte la forme d’un dièdre articulé au niveau d’une zone d’articulation disposée entre les faces du dièdre par déplacement relatif de ses faces, avec les faces du dièdre convergeant en direction de l’intérieur du sachet, en position dite fermée du bec verseur, et en direction de l’extérieur du sachet, en position dite ouverte du bec verseur, et en ce que l’ouverture d’accès est configurée pour passer d’une position fermée à une position ouverte, en parallèle du passage des faces du dièdre de la position correspondant à la position fermée du bec verseur à la position correspondant à la position ouverte du bec verseur. To this end, the subject of the invention is a packaging bag comprising a flexible body delimiting a storage enclosure, said body comprising at least two opposite faces and two bellows connecting said facing faces to each other, at least an access opening formed in said body at one of the bellows of the body, said access opening being able to pass from a closed position to an open position in which the bag is able to be emptied by said opening access and a pouring spout attached to the outer surface of the bag body at the bellows of the body equipped with the access opening, characterized in that the spout comprises a self-adhesive label and a positionable mask between at least one part of the self-adhesive label and the body of the bag, in that the self-adhesive label, which is a label at least partially separable from the body of the bag, is, at least before its first at least partial separation from the body of the bag, disposed on the body of the bag in a position in which all access to the access opening is prevented, in that said mask, of rigidity, preferably greater than the rigidity of the body, affects the shape of an articulated dihedron at a hinge area disposed between the faces of the dihedron by relative displacement of its faces , with the faces of the dihedron converging towards the inside of the bag, in the so-called closed position of the spout, and in the direction of the outside of the bag, in the so-called open position of the spout, and in that the opening of the access is configured to move from a closed position to an open position, in parallel with the passage of the dihedral faces from the position corresponding to the closed position of the spout to the position corresponding to the open position spout.
La conception du bec verseur réalisé à partir de la superposition d’un masque sous forme de dièdre et d’une étiquette autocollante permet une dépose automatique du bec verseur sur le film. The design of the spout made from the superposition of a dihedral mask and a self-adhesive label allows automatic removal of the spout on the film.
La possibilité de générer en parallèle du déplacement du bec verseur entre la position fermée et la position ouverte le passage de l’ouverture d’accès d’une position à une autre permet une simplicité d’utilisation en termes d’ouverture/fermeture du sachet. The possibility of generating in parallel the displacement of the spout between the closed position and the open position the passage of the access opening from one position to another allows an ease of use in terms of opening / closing the bag .
La coopération du bec verseur avec le soufflet du corps permet une refermeture de manière sûre du sachet, sans observer de béance incontrôlée du bec verseur. The cooperation of the spout with the bellow of the body allows a safe reclosing of the bag, without observing uncontrolled opening of the spout.
Selon un mode de réalisation de l’invention, l’ouverture d’accès délimitée par un bord et apte à passer de la position fermée à la position ouverte par écartement de parties de son bord présente une partie de son bord montée solidaire en déplacement d’au moins une partie du dièdre pour permettre, parallèlement au passage des faces du dièdre de la position correspondant à la position fermée du bec verseur à la position correspondant à la position ouverte du bec verseur, l’entrainement d’une partie du bord de l’ouverture d’accès dans le sens d’une ouverture de ladite ouverture d’accès. According to one embodiment of the invention, the access opening delimited by an edge and able to pass from the closed position to the open position by spacing portions of its edge has a portion of its edge mounted integral in displacement of at least a portion of the dihedron to allow, parallel to the passage of the dihedral faces from the position corresponding to the closed position of the spout at the position corresponding to the position open spout, the drive of a portion of the edge of the access opening in the direction of an opening of said access opening.
Selon un mode de réalisation de l’invention, le bec verseur est rapporté sur la surface externe du corps du sachet à recouvrement au moins partiel, de préférence à recouvrement total, de ladite ouverture d’accès en position fermée du bec verseur. Il est ainsi possible de s’affranchir d’un autre organe de refermeture du sachet. According to one embodiment of the invention, the pouring spout is attached to the outer surface of the body of the at least partial, preferably total overlap, pouch of said access opening in the closed position of the spout. It is thus possible to dispense with another device for closing the bag.
Selon un mode de réalisation de l’invention, le dièdre est divisé, suivant une ligne transversale à la zone d’articulation des faces du dièdre entre elles, en deux zones, une première zone, dans laquelle le dièdre est non adhéré au corps et vient, en position fermée, à recouvrement au moins partiel, de préférence à recouvrement total, de l’ouverture d’accès et une seconde zone, dans laquelle le dièdre est au moins localement fixé au corps. According to one embodiment of the invention, the dihedron is divided, along a line transverse to the zone of articulation of the faces of the dihedral between them, in two zones, a first zone, in which the dihedron is not adhered to the body and comes, in the closed position, overlapping at least partially, preferably fully overlapping, the access opening and a second zone, wherein the dihedron is at least locally attached to the body.
Le dièdre est dépourvu de fente ou d'ouverture en regard de l'ouverture d'accès du corps du sachet. Il en résulte une facilité de pose et d'utilisation. The dihedron has no slot or opening opposite the access opening of the body of the bag. This results in ease of installation and use.
Selon un mode de réalisation de l’invention, l’étiquette autocollante, au moins partiellement séparable du corps du sachet, est avant toute séparation au moins partielle du corps du sachet, disposée à recouvrement au moins des bords du dièdre disposés dans la première zone et de la zone du corps du sachet jouxtant lesdits bords du dièdre. Il en résulte une possibilité de fermeture hermétique du sachet. According to one embodiment of the invention, the self-adhesive label, at least partially separable from the body of the bag, is before any at least partial separation of the body of the bag, arranged to overlap at least the edges of the dihedron disposed in the first zone and the zone of the bag body adjacent said dihedral edges. This results in a possibility of sealing the bag.
Selon un mode de réalisation de l’invention, chaque face du dièdre présente une largeur, prise suivant une direction transversale à la zone d’articulation des faces du dièdre entre elles qui décroît depuis la partie de la face du dièdre la plus proche de l’ouverture d’accès en direction de la partie de la face du dièdre la plus éloignée de l’ouverture d’accès. According to one embodiment of the invention, each face of the dihedron has a width, taken along a direction transverse to the zone of articulation of the faces of the dihedral between them which decreases from the part of the face of the dihedron closest to the access opening towards the part of the face of the dihedron furthest from the access opening.
Selon un mode de réalisation de l’invention, les faces du dièdre sont, au niveau d’au moins une partie de la zone d’articulation, reliées l’une à l’autre de manière indirecte par l’intermédiaire du corps du sachet. According to one embodiment of the invention, the faces of the dihedral are, at the level at least a part of the hinge zone, connected to one another indirectly through the body of the bag.
Selon un mode de réalisation de l’invention, les faces du dièdre sont, au niveau d’au moins une partie de la zone d’articulation, reliées l’une à l’autre de manière dite directe par une liaison réalisée d’une seule pièce avec au moins l’une des faces du dièdre. According to one embodiment of the invention, the faces of the dihedral are, at the level of at least a part of the articulation zone, connected to each other in a direct manner by a connection made of a single piece with at least one of the faces of the dihedron.
Selon un mode de réalisation de l’invention, les faces du dièdre sont configurées pour passer de la position correspondant à la position fermée du bec verseur à la position correspondant à la position ouverte du bec verseur sous l’effet d’une poussée exercée à partir de l’intérieur du sachet, depuis l’intérieur en direction de l’extérieur du sachet, au niveau de la zone d’articulation du dièdre en regard de l’ouverture d’accès. Cette poussée est apte à être exercée à l’aide d’un doigt introduit dans le sachet, au niveau de l’ouverture d’accès. According to one embodiment of the invention, the faces of the dihedron are configured to move from the position corresponding to the closed position of the spout to the position corresponding to the open position of the spout under the effect of a thrust exerted to from inside the bag, from the inside towards the outside of the bag, at the hinge zone of the dihedral opposite the access opening. This thrust is able to be exerted with the aid of a finger introduced into the bag, at the level of the access opening.
Selon un mode de réalisation de l’invention, l’ouverture d’accès est une ouverture allongée qui s’étend sur au moins une partie de sa longueur suivant une direction transversale à la zone d’articulation des faces du dièdre. According to one embodiment of the invention, the access opening is an elongate opening which extends over at least a portion of its length in a direction transverse to the articulation zone of the faces of the dihedron.
Selon un mode de réalisation de l’invention, au moins le soufflet équipé du bec verseur est un soufflet à angle rentrant sur au moins une partie de sa surface, ce soufflet étant séparé de chacune des faces en regard du sachet par au moins une soudure le reliant à ladite face. According to one embodiment of the invention, at least the bellows equipped with the spout is a bellows angle retracted on at least a portion of its surface, this bellows being separated from each of the faces facing the bag by at least one weld connecting it to said face.
Selon un mode de réalisation de l’invention, le soufflet équipé du bec verseur est muni, sur au moins une partie de sa surface, d’une ligne de pliage séparant le soufflet en deux pans positionnables entre les faces en regard du sachet et en applique l’un contre l’autre, à l’état stocké à plat du sachet avec les faces en regard du sachet en appui l’une sur l’autre, cette ligne de pliage s’étendant dans l’alignement de la zone d’articulation du bec verseur en position fermée du bec verseur. La coopération bec verseur/soufflet permet une bonne refermeture du bec verseur, et l’obtention de positions stables d’ouverture et de fermeture du bec verseur. According to one embodiment of the invention, the bellows equipped with the spout is provided, on at least a portion of its surface, with a fold line separating the bellows in two positions that can be positioned between the facing faces of the bag and applied against each other, in the state stored flat of the bag with the facing faces of the bag resting on one another, this fold line extending in the alignment of the zone d articulation of the spout in the closed position of the spout. The spout / bellows cooperation allows a good reclosing of the spout, and obtaining stable positions of opening and closing of the spout.
Selon un mode de réalisation de l’invention, les faces en regard du corps sont des faces larges du corps et les soufflets sont des faces étroites du corps. Le bec verseur est donc positionné sur une face étroite du sachet. According to one embodiment of the invention, the facing faces of the body are large faces of the body and the bellows are narrow faces of the body. The spout is positioned on a narrow side of the bag.
Selon un mode de réalisation de l’invention, l’étiquette autocollante est munie d’un onglet de préhension. De préférence, cet onglet de préhension s’étend en regard de la deuxième zone du dièdre, pour permettre un tirage de l’étiquette depuis la deuxième zone du dièdre en direction de la première zone du dièdre, lors de la séparation de l’étiquette du corps. According to one embodiment of the invention, the self-adhesive label is provided with a gripping tab. Preferably, this gripping tab extends opposite the second zone of the dihedron, to allow a drawing of the label from the second zone of the dihedral towards the first zone of the dihedron, during the separation of the label from the body.
L’invention a encore pour objet un film bobiné apte à former après passage dans une ensacheuse, le corps d’un sachet du type précité, caractérisé en ce que le film est, avant passage dans l’ensacheuse, pré-équipé d’un bec verseur et prédécoupé pour ménager une ouverture apte à former une ouverture d’accès du sachet. The subject of the invention is also a wound film capable of forming after passing through a bagger, the body of a bag of the aforementioned type, characterized in that the film is, before passing through the bagger, pre-equipped with a spout and pre-cut to provide an opening adapted to form an access opening of the bag.
L’invention a encore pour objet un procédé de fabrication d’un sachet du type précité dont le corps est réalisé par conformation d’un film à l’aide d’une ensacheuse, caractérisé en ce que le procédé comprend, avant conformation du film par l’ensacheuse, une opération de découpe du film pour ménager au moins une ouverture apte à former une ouverture d’accès du sachet et une opération de fixation du bec verseur au film.

Comme mentionné ci-dessus, le sachet 1 objet de l’invention est un sachet d’emballage de produit en vrac et est vidangeable au moins par déversement. Ce sachet 1 d’emballage comprend un corps 2 souple délimitant une enceinte 3 de stockage du produit stocké en vrac à l’intérieur de ladite enceinte 3. As mentioned above, the bag 1 object of the invention is a bag of bulk product packaging and is drainable at least by spillage. This packing bag 1 comprises a flexible body 2 delimiting an enclosure 3 for storing the product stored in bulk within said pregnant 3.
Ce corps 2 peut être formé par conformation d’un film à l’aide d’une ensacheuse. Ce corps 2 est un corps tubulaire formant une gaine fermée à chacune de ses extrémités par une soudure 6 transversale. Ces soudures 6 transversales sont au nombre de deux, dans les exemples représentés. This body 2 can be formed by shaping a film using a bagger. This body 2 is a tubular body forming a sheath closed at each of its ends by a transverse weld 6. These transverse welds are two in number, in the examples shown.
Les soudures 6 transversales sont reliées entre elles par des soudures 7 longitudinales, ici au nombre de quatre. Les soudures 7 longitudinales divisent le corps 2 en deux faces en regard et deux soufflets. Le corps 2 comprend ainsi au moins deux faces 4 en regard et deux soufflets 5 reliant lesdites faces 4 en regard. The transverse welds 6 are interconnected by longitudinal welds 7, here four in number. The longitudinal welds 7 divide the body 2 in two opposite faces and two bellows. The body 2 thus comprises at least two faces 4 opposite and two bellows 5 connecting said faces 4 opposite.
Les faces 4 en regard forment les faces larges du corps 2 et les soufflets 5 forment les faces étroites du corps 2. Les soufflets 5 permettent d’écarter et de rapprocher au moins une partie des faces 4 en regard l’une de l’autre. The facing faces 4 form the broad faces of the body 2 and the bellows 5 form the narrow faces of the body 2. The bellows 5 allow to separate and bring closer at least a portion of the faces 4 opposite one another .
Chaque soufflet 5 est donc séparé de chacune des faces 4 en regard par une soudure 7 longitudinale. Each bellows 5 is separated from each of the facing faces 4 by a longitudinal weld 7.
Les soudures 7 longitudinales bordant un même soufflet 5 tendent à être rappelées l'une contre l'autre grâce aux soudures transversales et contraignent le soufflet dans sa position. The longitudinal welds 7 bordering the same bellows 5 tend to be biased against each other through the transverse welds and force the bellows in its position.
Au moins l’un des soufflets, dans l’exemple représenté, chacun des soufflets, est un soufflet à angle rentrant sur au moins une partie de sa surface. Ce soufflet est formé, sur au moins une partie de sa surface, par repli et maintien d’une partie de la gaine entre les faces 4 en regard du corps. Le maintien s'opère à l'aide des soudures 6 transversales et d'un collage des extrémités desdites soudures. En effet, la partie repliée de la gaine est fermée à chacune de ses extrémités par deux soudures transversales qui ferment chacune un pli du repli de la gaine, ces deux soudures transversales étant ensuite accolées l'une à l'autre par collage. La réalisation d'un tel soufflet est classique et connue. Ainsi, au moins le soufflet muni du bec verseur, dans l’exemple représenté, chaque soufflet 5, est muni sur au moins une partie de sa surface d’une ligne 51 de pliage séparant le soufflet 5 en deux pans 52 positionnables entre les faces en regard du sachet 1 et en applique l’un contre l’autre, à l’état stocké à plat du sachet 1 avec les faces 4 en regard du sachet, en appui l’une sur l’autre. At least one of the bellows, in the example shown, each of the bellows, is a bellows angle retracted on at least a portion of its surface. This bellows is formed, on at least a portion of its surface, by folding and maintaining a portion of the sheath between the faces 4 facing the body. The maintenance is carried out using the transverse welds 6 and a bonding of the ends of said welds. Indeed, the folded portion of the sheath is closed at each of its ends by two transverse welds which each close a fold of the fold of the sheath, these two transverse welds being then contiguous to one another by gluing. The realization of such a bellows is conventional and known. Thus, at least the bellows provided with the spout, in the example shown, each bellows 5, is provided on at least a portion of its surface with a line 51 of folding separating the bellows 5 in two panels 52 positionable between the faces next to the bag 1 and applies against each other, in the stored state flat of the bag 1 with the faces 4 facing the bag, resting on one another.
Le sachet 1 d’emballage comprend encore au moins une ouverture 8 d’accès ménagée dans ledit corps 2, au niveau de l’un des soufflets 5 du corps 2. Cette ouverture 8 d’accès est apte à passer d’une position fermée à une position ouverte dans laquelle le sachet est apte à être vidangé par ladite ouverture 8 d’accès. The packaging bag 1 further comprises at least one access opening 8 formed in said body 2, at one of the bellows 5 of the body 2. This access opening 8 is able to pass from a closed position an open position in which the bag is adapted to be emptied by said access opening 8.
Le sachet 1 comprend enfin un bec 9 verseur rapporté sur la surface externe du corps 2 du sachet 1 au niveau du soufflet 5 du corps équipé de l’ouverture 8 d’accès. Ce bec verseur est positionné dans une zone du soufflet proche des soudures transversales. Ce bec verseur 9 comprend une étiquette 10 autocollante et un masque 11 positionnable entre au moins une partie de l’étiquette 10 autocollante et le corps 2 du sachet 1. The sachet 1 finally comprises a spout 9 poured on the outer surface of the body 2 of the bag 1 at the bellows 5 of the body equipped with the opening 8 access. This spout is positioned in a zone of the bellows close to the transverse welds. This spout 9 comprises a self-adhesive label and a mask 11 that can be positioned between at least a portion of the self-adhesive label and the body 2 of the bag 1.
Le masque 11 , de rigidité, de préférence, supérieure à la rigidité du corps 2 affecte la forme d’un dièdre 12. Ce dièdre 12 est dépourvu de fente ou d'ouverture traversante en regard de l'ouverture 8 d'accès du corps du sachet. Ce dièdre présente une zone 15 d’articulation disposée entre les faces 13 du dièdre. Ce dièdre est ainsi un dièdre articulé par déplacement relatif de ses faces 13, avec les faces du dièdre convergeant en direction de l’intérieur du sachet 1 en position fermée du bec verseur et en direction de l’extérieur du sachet 1 en position ouverte du bec verseur 9. The mask 11, of rigidity, preferably greater than the rigidity of the body 2 has the shape of a dihedron 12. This dihedron 12 has no slot or through opening facing the access opening 8 of the body of the bag. This dihedron has a hinge zone disposed between the faces 13 of the dihedron. This dihedron is thus a dihedron articulated by relative displacement of its faces 13, with the faces of the dihedron converging towards the inside of the bag 1 in the closed position of the spout and towards the outside of the bag 1 in the open position of the spout 9.
Ce déplacement relatif des faces du dièdre est un déplacement à pivotement suivant une ligne perpendiculaire aux lignes de soudure transversales du corps 2. Chaque face 13 du dièdre 12 est formée par un panneau réalisé en un matériau, de préférence, plus rigide que le matériau constitutif du corps 2 de sachet. Les faces 13 du dièdre peuvent être, au niveau d’au moins une partie de la zone 15 d’articulation, reliées l’une à l’autre de manière indirecte, par l’intermédiaire du corps 2 du sachet. Dans ce cas, une partie du corps 2 du sachet forme une liaison-charnière entre lesdites faces du dièdre. This relative displacement of the dihedral faces is a pivotal displacement along a line perpendicular to the transverse weld lines of the body 2. Each face 13 of the dihedron 12 is formed by a panel made of a material, preferably more rigid than the material constituting the bag body 2. The faces 13 of the dihedral may be, at the level of at least a portion of the hinge zone 15, connected to one another indirectly, via the body 2 of the bag. In this case, a body portion 2 of the bag forms a hinge-connection between said faces of the dihedron.
Les faces 13 du dièdre peuvent encore, au niveau d’au moins une partie de la zone 15 d’articulation, être reliées l’une à l’autre de manière directe par une liaison réalisée d’une seule pièce avec au moins l’une des faces 13 du dièdre 12. Dans ce cas, la liaison peut être formée par une ligne de pliage entre lesdites faces du dièdre, ou une ligne de découpe partielle entre les faces du dièdre. Cette liaison peut encore être réalisée par une patte s’étendant en saillie de l’une des faces du dièdre et venant se fixer sur l’autre face du dièdre. Indépendamment du mode de réalisation de la zone 15 d’articulation entre les faces du dièdre pour former l’équivalent d’une liaison pivot entre les faces du dièdre par pivotement autour d’un axe transversal, de préférence perpendiculaire aux lignes de soudure transversales du corps 2, lorsque le soufflet 5 équipé du bec verseur 9 est muni sur au moins une partie de sa surface d’une ligne 51 de pliage séparant le soufflet 5 en deux pans 52, cette ligne 51 de pliage s’étend dans l’alignement de la zone 15 d’articulation du bec verseur 9 en position fermée du bec verseur. The faces 13 of the dihedral may, at at least a portion of the hinge zone 15, be connected to each other in a direct manner by a connection made in one piece with at least one one of the faces 13 of the dihedron 12. In this case, the connection may be formed by a fold line between said faces of the dihedron, or a partial cutting line between the faces of the dihedron. This connection can still be achieved by a tab extending projecting from one of the faces of the dihedron and being fixed on the other face of the dihedron. Independently of the embodiment of the hinge zone between the faces of the dihedron to form the equivalent of a pivot connection between the faces of the dihedron by pivoting about a transverse axis, preferably perpendicular to the transverse weld lines of the body 2, when the bellows 5 equipped with the spout 9 is provided on at least a portion of its surface with a fold line 51 separating the bellows 5 in two panels 52, this fold line 51 extends in the alignment the zone 15 of articulation of the spout 9 in the closed position of the spout.
Dans l’exemple représenté, chaque face 13 du dièdre 12 présente une largeur prise suivant une direction transversale à la zone 15 d’articulation des faces 13 du dièdre 12 entre elles, qui décroît depuis la partie de la face 13 du dièdre 12 la plus proche de l’ouverture 8 d’accès en direction de la partie de la face 13 du dièdre 12 la plus éloignée de l’ouverture 8 d’accès. En particulier, le dièdre présente une forme générale triangulaire dont certains sommets peuvent être tronqués. Grâce au fait que le dièdre du bec verseur est rapporté sur le soufflet qui est à angle rentrant, le dièdre ne peut pas occuper une position stable d'équilibre dans laquelle les faces du dièdre seraient coplanaires. In the example shown, each face 13 of the dihedron 12 has a width taken in a direction transverse to the articulation zone 15 of the faces 13 of the dihedron 12 between them, which decreases from the portion of the face 13 of the dihedron 12 most close to the access opening 8 towards the portion of the face 13 of the dihedron 12 farthest from the access opening 8. In particular, the dihedron has a generally triangular shape, some vertices may be truncated. Thanks to the fact that the dihedral of the spout is attached to the bellows which is at a re-entrant angle, the dihedron can not occupy a stable equilibrium position in which the dihedral faces are coplanar.
Le bec verseur 9, qui peut être rapporté sur la surface externe du corps 2 du sachet à recouvrement au moins partiel de l’ouverture 8 d’accès en position fermée du bec verseur 9 est, dans les exemples représentés, rapporté à recouvrement total de l’ouverture 8 d’accès, en position fermée du bec verseur. The spout 9, which can be attached to the outer surface of the body 2 of the bag at least partially covering the opening 8 for access in the closed position of the spout 9 is, in the examples shown, reported to total recovery of the access opening 8, in the closed position of the spout.
Ce dièdre 12 est divisé suivant une ligne transversale à la zone 15 d’articulation des faces 13 du dièdre entre elles en deux zones : une première zone 16 dans laquelle le dièdre 12 est non adhéré au corps 2 et vient en position fermée à recouvrement total de l’ouverture 8 d’accès, et une seconde zone 17 dans laquelle le dièdre 12 est au moins localement fixé au corps 2. Dans la première zone, le dièdre 12 est dépourvu d'ouverture ou de fente en regard de l'ouverture 8 d'accès pour permettre une bonne obturation de l'ouverture 8 d'accès. This dihedron 12 is divided along a line transverse to the area 15 of articulation of the faces 13 of the dihedron between them in two zones: a first zone 16 in which the dihedron 12 is not adhered to the body 2 and comes in fully closed closed position of the access opening 8, and a second zone 17 in which the dihedron 12 is at least locally attached to the body 2. In the first zone, the dihedron 12 has no opening or slot opposite the opening 8 access to allow a good closure of the access opening 8.
En variante, la première zone 16 du dièdre aurait pu venir uniquement à recouvrement partiel de l’ouverture 8 d’accès, et venir recouvrir simplement une partie de bord de l’ouverture 8 d’accès. A nouveau dans ce cas, cette première zone 16 du dièdre est dépourvue d'ouverture ou de fente en regard de l'ouverture 8 d'accès. In a variant, the first zone 16 of the dihedron could have come only partially to cover the access opening 8, and simply cover an edge portion of the access opening 8. Again in this case, this first zone 16 of the dihedron has no opening or slot facing the access opening 8.
Dans l’exemple représenté, le dièdre est dans la seconde zone 17 fixée par collage au corps 2 de sachet. In the example shown, the dihedron is in the second zone 17 fixed by bonding to the bag body 2.
L’ouverture 8 d’accès est quant à elle une ouverture allongée, en l’occurrence une fente qui s’étend sur au moins une partie de sa longueur suivant une direction transversale à la zone 15 d’articulation des faces 13 du dièdre 12. The access opening 8 is in turn an elongate opening, in this case a slot which extends over at least part of its length in a direction transverse to the articulation zone of the faces 13 of the dihedron 12. .
Cette ouverture 8 d’accès est configurée pour passer d’une position fermée à une position ouverte, en parallèle du passage des faces 13 du dièdre 12 de la position correspondant à la position fermée du bec verseur 9 à la position correspondant à la position ouverte du bec verseur 9. This access opening 8 is configured to pass from a closed position to an open position, in parallel with the passage of the faces 13 of the dihedron 12 of the position corresponding to the closed position of the spout 9 at the position corresponding to the open position of the spout 9.
En particulier, l’ouverture 8 d’accès, délimitée par un bord 14 et apte à passer de la position fermée à la position ouverte par écartement de parties 141 , 142 de son bord 14, présente une partie 141 de son bord 14 montée solidaire en déplacement d’au moins une partie du dièdre 12 pour permettre, parallèlement au passage des faces 13 du dièdre 12 de la position correspondant à la position fermée du bec verseur 9 à la position correspondant à la position ouverte du bec verseur 9, l’entrainement d’une partie du bord 14 de l’ouverture 8 d’accès dans le sens d’une ouverture de ladite ouverture 8 d’accès. In particular, the access opening 8, delimited by an edge 14 and able to pass from the closed position to the open position by spacing portions 141, 142 from its edge 14, has a portion 141 of its edge 14 mounted integral with moving at least a portion of the dihedron 12 to allow, parallel to the passage of the faces 13 of the dihedron 12 from the position corresponding to the closed position of the spout 9 to the position corresponding to the open position of the spout 9, the driving a portion of the edge 14 of the access opening 8 in the direction of an opening of said access opening 8.
La partie 141 de bord de l’ouverture 8 d’accès montée solidaire, c’est-à-dire entraînable en déplacement par au moins une partie du dièdre est formée par l’un des bords longitudinaux ou lèvres de la fente, tandis que l’autre bord longitudinal ou lèvre de la fente est non entraîné en déplacement lors de l’ouverture du bec verseur. The edge portion 141 of the access opening 8 mounted integrally, that is to say drivable in displacement by at least a portion of the dihedron is formed by one of the longitudinal edges or lips of the slot, while the other longitudinal edge or lip of the slot is not driven in displacement during the opening of the spout.
En vue d’une ouverture du bec verseur, les faces 13 du dièdre 12 sont configurées pour passer de la position correspondant à la position fermée du bec verseur 9 à la position correspondant à la position ouverte du bec verseur 9, sous l’effet d’une poussée exercée à partir de l’intérieur du sachet 1 depuis l’intérieur en direction de l’extérieur du sachet 1 au niveau de la zone 15 d’articulation du dièdre 12 en regard de l’ouverture 8 d’accès. In order to open the spout, the faces 13 of the dihedron 12 are configured to move from the position corresponding to the closed position of the spout 9 to the position corresponding to the open position of the spout 9, under the effect of a thrust exerted from the inside of the bag 1 from the inside toward the outside of the bag 1 at the area 15 of articulation of the dihedron 12 opposite the opening 8 access.
Cette poussée est apte à être exercée à l’aide d’un doigt introduit dans ledit sachet au niveau de l’ouverture 8 d’accès. De la même manière, le retour du bec verseur en position fermée peut s’opérer avec un seul doigt, par simple poussée exercée à l’aide d’un doigt sur la face externe du dièdre en direction de l’intérieur du sachet. This thrust is able to be exerted with the aid of a finger introduced into said bag at the access opening 8. In the same way, the return of the spout in the closed position can operate with a single finger, by simply pushing with the help of a finger on the outer face of the dihedral towards the inside of the bag.
Grâce au positionnement du dièdre sur un soufflet du corps, à la conception du soufflet, et au positionnement relatif de la zone d’articulation du dièdre et de la ligne de pliage du soufflet, il en résulte un maintien sûr en position ouverte ou fermée du bec verseur. Thanks to the positioning of the dihedron on a bellows of the body, the design of the bellows, and the relative positioning of the hinge region of the dihedral and the fold line of the bellows, it results in a secure hold in the open or closed position of the spout.
Pour parfaire l’ensemble, et notamment obtenir une fermeture hermétique du sachet au moins avant ouverture, et empêcher une ouverture intempestive du dièdre du bec verseur, le bec verseur comprend, comme mentionné ci-dessus, une étiquette 10 autocollante. Cette étiquette 10, qui est une étiquette au moins partiellement séparable du corps du sachet 1 est, au moins avant sa première séparation au moins partielle du corps 2 du sachet 1 , disposée sur le corps du sachet 1 , dans une position dans laquelle tout accès à l’ouverture 8 d’accès est empêchée. To perfect the assembly, and in particular to obtain a hermetic closure of the bag at least before opening, and prevent inadvertent opening of the dihedron spout, the spout comprises, as mentioned above, a self-adhesive label. This label 10, which is a label at least partially separable from the body of the bag 1 is, at least before its first at least partial separation of the body 2 of the bag 1, disposed on the body of the bag 1, in a position in which any access at the access opening 8 is prevented.
Dans l’exemple représenté, cette étiquette 10 autocollante est entièrement séparable du corps du sachet 1. Cette étiquette 10 autocollante est, avant toute séparation du sachet, disposée à recouvrement au moins des bords du dièdre 12 disposés dans la première zone 16, et de la zone du corps 2 du sachet jouxtant lesdits bords du dièdre 12. Cette étiquette 10 autocollante peut être réalisée sous forme d'une simple couche ou être, comme dans les exemples représentés, formée au moins localement de deux épaisseurs. Dans ce cas, par exemple, le dièdre est relié par une ligne de découpe à une partie autocollante séparable qui entoure le dièdre et qui fait partie de l'étiquette 10 autocollante. In the example shown, this self-adhesive label 10 is completely separable from the body of the bag 1. This self-adhesive label 10 is, before any separation of the bag, arranged to overlap at least the edges of the dihedron 12 disposed in the first zone 16, and of the zone of the body 2 of the bag adjacent said edges of the dihedron 12. This self-adhesive label 10 can be made in the form of a single layer or be, as in the examples shown, formed at least locally of two thicknesses. In this case, for example, the dihedron is connected by a cutting line to a separable adhesive part which surrounds the dihedron and which is part of the self-adhesive label.
Cette partie séparable est détachée du corps du sachet lors de l'enlèvement de l'étiquette 10 dont elle constitue une partie. Cette conception de l'étiquette 10 autocollante doublée localement permet d'éviter un décollement intempestif de l'étiquette avant détachement de l'étiquette du sachet. Ce détachement non souhaité de l'étiquette peut être observé dans le cas d'une étiquette 10 autocollante d'épaisseur constante. This separable portion is detached from the body of the bag during the removal of the label 10 of which it forms a part. This design of the locally lined self-adhesive label 10 avoids inadvertent detachment of the label before detaching the label from the bag. This unwanted detachment of the label can be observed in the case of a self-adhesive label of constant thickness.
Pour permettre son décollage du corps 2, l’étiquette 10 autocollante est munie d’un onglet 18 de préhension. L’onglet 18 de préhension s’étend en regard de la deuxième zone du dièdre, pour permettre un tirage de l’étiquette depuis la deuxième zone du dièdre vers la première zone du dièdre, lors de la séparation de l’étiquette du corps 2. To allow its take-off of the body 2, the self-adhesive label 10 is provided with a tab 18 for gripping. The grip tab 18 extends next to the second zone of the dihedron, to allow a drawing of the label from the second zone of the dihedron to the first zone of the dihedron, during the separation of the label of the body 2.
Pour permettre une fabrication aisée d’un sachet tel que décrit ci-dessus, avec le corps du sachet réalisé par conformation d’un film à l’aide d’une ensacheuse, on procède généralement avant conformation du film par l’ensacheuse, à une opération de découpe du film pour ménager au moins une ouverture apte à former une ouverture d’accès du sachet, et une opération de fixation du bec verseur au film. Ainsi, le film 20 bobiné, apte à former après passage dans une ensacheuse le corps d’un sachet 1 est, avant passage dans l’ensacheuse, prééquipé d’un bec verseur 9 et prédécoupé pour ménager une ouverture apte à former une ouverture 8 d’accès du sachet 1. To allow easy manufacture of a bag as described above, with the body of the bag made by conforming a film with a bagger, it is generally carried out before shaping the film by the bagger, to a cutting operation of the film to provide at least one aperture adapted to form an access opening of the bag, and an attachment operation of the spout to the film. Thus, the wound film 20, capable of forming after passing through a bagger the body of a bag 1 is, before passing through the bagger, pre-equipped with a spout 9 and pre-cut to provide an opening capable of forming an opening 8 bag access 1.
L’ensacheuse permet une conformation du film sous forme d’un corps tubulaire fermé à chacune de ses extrémités par des soudures transversales et pourvu de soudures longitudinales, comme mentionné ci-dessus. The bagger allows a conformation of the film in the form of a tubular body closed at each of its ends by transverse welds and provided with longitudinal welds, as mentioned above.
Pour permettre une vidange du sachet, on procède, lors de la première vidange, comme suit : on sépare l’étiquette 10 autocollante du sachet par saisie de l’étiquette 10 au niveau de son onglet de préhension, puis tirage de l’étiquette. On réalise ensuite à l’ouverture du bec verseur comme mentionné ci-dessus, par introduction d'un doigt dans l'ouverture d'accès, puis poussée à l’aide du doigt sur le dièdre pour l’ouvrir. On obtient ainsi, en parallèle de l’ouverture du bec verseur, une ouverture de la fente par écartement de l’un de ses bords. On saisit alors le sachet par ses faces en regard, et on incline le sachet pour permettre une vidange par déversement de son contenu au niveau du bec verseur. Une fois la vidange opérée, le bec verseur peut être refermé par pression exercée sur l’extérieur du dièdre, en direction de l’intérieur du sachet. L’étiquette autocollante peut alors être repositionnée ou non, selon que l’on souhaite une refermeture hermétique ou pas du bec verseur et de l’ouverture d’accès. To allow the bag to be emptied, the first emptying is carried out as follows: the self-adhesive label is separated from the bag by grasping the label 10 at its gripping tab and then pulling the label. Then is made to the opening of the spout as mentioned above, by introducing a finger in the access opening, then pushed with the finger on the dihedron to open it. Thus, in parallel with the opening of the spout, an opening of the slot by spacing one of its edges. The bag is then grasped by its opposite faces, and the bag is tilted to allow emptying by pouring of its contents at the spout. Once emptying, the spout can be closed by pressure exerted on the outside of the dihedron, towards the inside of the bag. The self-adhesive label can then be repositioned or not, depending on whether it is desired to hermetically reclose or not the spout and the access opening.
Une nouvelle opération d’ouverture du bec verseur peut être opérée à tout moment, de manière similaire à ce qui a été décrit ci-dessus. A new operation of opening the spout can be operated at any time, similar to what has been described above.
Il résulte de la conception du sachet telle que décrite ci-dessus une simplicité d’utilisation et une grande fiabilité des positions d’ouverture et de fermeture du bec verseur. It follows from the design of the bag as described above simplicity of use and high reliability of the opening and closing positions of the spout.
