Description

EMBALLAGE AVEC SYSTEME DE FERMETURE AVEC COQUE, PROCEDE POUR SA FABRICATION PACKAGE WITH CLOSURE SYSTEM WITH SHELL, METHOD FOR THE PRODUCTION THEREOF
L'invention a pour objet un nouveau système de fermeture, adapté sur des emballages de type sachets, notamment en plastique. Ces emballages ou sachets peuvent être des "Doypack" ou des sachets dits "trois soudures".The subject of the invention is a new closure system, suitable for packaging of the bag type, in particular plastic. These packages or sachets can be "Doypack" or sachets called "three welds".
On connaît déjà de nombreux emballages ou sachets plastiques, munis ou non de valve. GB-A- 826 784 décrit un sachet qui est obtenu par pliage successif d'un film plastique. Ce film est plié une première fois le long d'une droite portant un orifice central, deux zones de soudure en V sont appliquées, puis le film est replié sur lui-même. Les trois côtés libres sont soudés, ainsi qu'une partie du quatrième côté portant le soufflet avec les soudures en V. La présence de l'ouverture au fond du soufflet, ainsi que la présence des deux soudures en V et la soudure partielle du côté de l'ouverture, permettraient un fonctionnement correct de la valve formée par l'orifice central. FR-A- 2 711 115 décrit un sachet gonflable muni d'une valve . Ce sachet est obtenu en formant deux soudures parallèles dans un film replié sur lui-même, qui est ensuite à nouveau replié sur lui-même, d'une façon similaire à celle de GB-A-826 781. Dans ce cas cependant, le film doublement replié sur lui-même est soudé de sorte à laisser les bords du film repliés accessibles de l'extérieur.Numerous packaging or plastic bags are already known, with or without a valve. GB-A- 826 784 describes a sachet which is obtained by successive folding of a plastic film. This film is folded for the first time along a straight line carrying a central orifice, two V-shaped welding zones are applied, then the film is folded back on itself. The three free sides are welded, as well as part of the fourth side carrying the bellows with the V welds. The presence of the opening at the bottom of the bellows, as well as the presence of the two V welds and the partial weld on the side. of the opening, would allow correct operation of the valve formed by the central orifice. FR-A- 2 711 115 describes an inflatable bag fitted with a valve. This sachet is obtained by forming two parallel seals in a film folded back on itself, which is then again folded back on itself, in a similar manner to that of GB-A-826 781.

L'invention propose un emballage avec obturateur, cet obturateur présentant une coque mobile dont les états de fléchissement définissent des positions d'ouverture et de fermeture de l'obturateur, la coque mobile disposant de moyens pour inverser sa flexion. Un tel obturateur peut par exemple être obtenu en formant des pivots entre cette coque mobile et une coque fixe concave, et en munissant cette coque mobile de moyens d'inversion de flexion. La figure 1 montre un emballage 1 selon un premier mode de réalisation de l'invention présentant un obturateur 2. Dans ce mode de réalisation, la coque mobile présente une rigidité inférieure à la rigidité de la coque fixe. L'obturateur 2 comprend une coque fixe concave 3 en vis-à-vis d'une coque mobile 4. La coque mobile est articulée suivant deux pivots parallèles 5 et 6 sur la coque fixe. La coque mobile présente avantageusement, selon une variante décrite par la suite, deux protubérances d ' actionnement 7 et 8 se prolongeant au- delà des pivots. L'emballage comprend également deux feuilles 9 et 10 en vis-à-vis, assemblées pour former un réservoir. Ces feuilles sont assemblées de façon étanche sur leur périphérie par une soudure 11.The invention provides a packaging with shutter, this shutter having a movable shell whose deflection states define the open and closed positions of the shutter, the movable shell having means to reverse its bending. Such a shutter can for example be obtained by forming pivots between this movable shell and a concave fixed shell, and by providing this movable shell with bending inversion means. Figure 1 shows a package 1 according to a first embodiment of the invention having a shutter 2. In this embodiment, the movable shell has a rigidity less than the rigidity of the fixed shell. The shutter 2 comprises a concave fixed shell 3 opposite a movable shell 4. The movable shell is articulated according to two parallel pivots 5 and 6 on the fixed shell. The movable shell advantageously has, according to a variant described below, two actuating protuberances 7 and 8 extending beyond the pivots. The packaging also includes two facing sheets 9 and 10, assembled to form a reservoir. These sheets are tightly assembled on their periphery by a weld 11.
Ces feuilles sont constituées de matière classique dans l'art, notamment en matière plastique telle que PET, OPA, OPP, PA, PE, PP ou du encore du papier aluminium etc. Ces feuilles peuvent être utilisées en monocouche ou en structure multicouche, complexée ou coextrudée par exemple. Ces deux feuilles sont notamment semi-rigides, en ce sens qu'elles sont susceptibles d'être déformées pour accepter la dilatation du sachet tout en fournissant un maintien général au sachet. L'épaisseur de ces deux feuilles est classique dans l'art, par exemple une épaisseur comprise entre 30 et 1000 μm, et de préférence entre 60 et 250 μm.These sheets are made of material conventional in the art, in particular plastic such as PET, OPA, OPP, PA, PE, PP or aluminum foil etc. These sheets can be used in monolayer or in multilayer structure, complexed or coextruded for example. These two sheets are in particular semi-rigid, in the sense that they are capable of being deformed to accept the expansion of the sachet while providing general support for the sachet. The thickness of these two sheets is conventional in the art, for example a thickness between 30 and 1000 μm, and preferably between 60 and 250 μm.
L'emballage présente une épaisseur globale en général inférieure à 2 mm, de préférence inférieure à 500 μm.The packaging has an overall thickness generally less than 2 mm, preferably less than 500 μm.
Ces emballages sont appropriés dans tous les domaines techniques, notamment alimentaire, chimie, détergents, cosmétique; et ce pour des liquides, des poudres, des granulés ou des solides de petites tailles (par exemple des bonbons) , voire même des gaz .These packaging are suitable in all technical fields, in particular food, chemicals, detergents, cosmetics; and this for liquids, powders, granules or small solids (for example candies), or even gases.
Les figures 2 et 3 représentent en perspective les coques 3 et 4 de 1 ' obturateur 2 de la figure 1. La coque 3 est une coque fixe et concave présentant deux bords 31 et 32 et une face d'obturation 33. La coque concave 3 peut être obtenue à partir d'un secteur angulaire de cylindre ou par formage à partir d'une forme plane par exemple. La coque 4 est une coque souple et mobile, initialement concave sous l'effet des pivots et de la coque fixe; en effet la longueur développée entre pivots 1 de la coque mobile est supérieure à la distance d entre articulations. La coque 4 présente deux bords 41 et 42. La coque 4 présente une face d'obturation 43 mobile, destinée à venir en contact ou à s'écarter de la face 33. Les faces d'obturation 33 et 43 présentent avantageusement une même courbure car une fois la coque mobile 4 en contact avec la coque fixe, elle en épouse alors la courbure. Les bords 41 et 42 s'articulent respectivement aux bords 31 et 32, en formant les pivots 5 et 6 représentés à la figure 1. Les pivots 5 et 6 représentés sont parallèles mais ils pourraient aussi être disposés en V. Ainsi, il est plus aisé de fléchir la coque 4. La coque 4 comporte également avantageusement deux protubérances 7 et 8 faisant saillie par rapport à la face d'obturation 43, respectivement à partir des bords 41 et 42. Ces protubérances sont réalisées dans la continuité de la face d'obturation 43. Ainsi, l'application d'une force, dont la ligne d'action ne passe pas par les pivots 5 et 6, sur une des protubérances 7 ou 8, modifie la courbure de la face d'obturation 43 de la coque mobile 4. Ces protubérances ont de préférence une forme de bande et peuvent ainsi fournir une surface utile conséquente, et peuvent aisément être réalisées lors de la formation de la coque 4. Les protubérances pourraient n'être que des ergots dépassant des pivots. Les moyens d'inversion de flexion pourraient aussi se présenter autrement que sous forme de ces protubérances mais se présenter sous forme d'excroissances ou de languettes susceptibles d'être manipulées par l'utilisateur, comme cela sera décrit par la suite. Les figures 4 et 5 représentent en coupe suivant une section normale à un axe des coques, l'obturateur 1, respectivement en position fermée et ouverte. Dans la figure 4, on observe l'obturateur en position fermée. La coque mobile 4 est alors fléchie dans une première position stable. Dans cette position, la face d'obturation 43 de la coque mobile est maintenue accolée contre (elle "épouse") la face d'obturation 33 de la coque fixe et bouche ainsi le passage de l'ouverture de l'emballage dont le contenu est gazeux, liquide ou solide. Les bords 41 et 42 de la coque mobile sont articulés suivant deux pivots 5 et 6 aux bords 31 et 32 de la coque fixe respectivement. La rigidité de la coque fixe 3 permet de maintenir les bords 41 et 42 à un ecartement inférieur à la longueur de matière de la coque mobile qui les joint .Figures 2 and 3 show in perspective the shells 3 and 4 of the shutter 2 of Figure 1. The shell 3 is a fixed and concave shell having two edges 31 and 32 and a sealing face 33. The concave shell 3 can be obtained from an angular sector of the cylinder or by forming from a plane shape for example. The shell 4 is a flexible and mobile shell, initially concave under the effect of the pivots and the fixed shell; indeed the length developed between pivots 1 of the movable shell is greater than the distance d between joints. The shell 4 has two edges 41 and 42. The shell 4 has a movable closure face 43, intended to come into contact or to move away from the face 33. The closure faces 33 and 43 advantageously have the same curvature because once the movable shell 4 in contact with the fixed shell, it then matches the curvature. The edges 41 and 42 are articulated respectively to the edges 31 and 32, forming the pivots 5 and 6 shown in FIG. 1. The pivots 5 and 6 shown are parallel but they could also be arranged in a V. Thus, it is more easy to flex the shell 4. The shell 4 also advantageously comprises two protuberances 7 and 8 projecting relative to the closure face 43, respectively from the edges 41 and 42. These protrusions are produced in continuity with the face d shutter 43. Thus, the application of a force, the line of action of which does not pass through the pivots 5 and 6, on one of the protrusions 7 or 8, modifies the curvature of the shutter face 43 of the movable shell 4. These protrusions preferably have the shape of a strip and can thus provide a substantial useful surface, and can easily be produced during the formation of the shell 4. The protrusions could be only lugs protruding from the pivots. The flexion inversion means could also be presented other than in the form of these protuberances but may be in the form of protuberances or tongues capable of being manipulated by the user, as will be described below. Figures 4 and 5 show in section along a section normal to an axis of the shells, the shutter 1, respectively in the closed and open position. In Figure 4, we observe the shutter in the closed position. The movable shell 4 is then bent into a first stable position. In this position, the shutter face 43 of the movable shell is held contiguous against (it "marries") the shutter face 33 of the fixed shell and thus blocks the passage of the opening of the packaging, the contents of which is gaseous, liquid or solid. The edges 41 and 42 of the movable shell are articulated along two pivots 5 and 6 at the edges 31 and 32 of the fixed shell respectively. The rigidity of the fixed shell 3 keeps the edges 41 and 42 at a spacing less than the length of material of the movable shell which joins them.
Dans la figure 5, on observe l'obturateur en position ouverte. La coque mobile est alors fléchie dans une deuxième position stable. Dans cette position, la face d'obturation 43 de la coque mobile est écartée de la face d'obturation 33 de la coque fixe et libère ainsi le passage de l'ouverture de l'emballage. La rigidité de la coque 2 permet de maintenir les bords 41 et 42 à un ecartement inférieur à la longueur de matière de la coque mobile qui les joint. Ainsi, la coque mobile est contrainte dans la position stable d'ouverture. La coque 4 est alors dans une deuxième position stable, dans laquelle sa courbure est inversée par rapport à la position fermée . Comme cela est représenté à la figure 6, le passage d'une position à l'autre peut être obtenu de préférence par des moyens d'inversion de flexion disposés sur la coque mobile. Dans le mode de réalisation présenté, ces moyens correspondent aux protubérances 7 et 8 , s ' étendant latéralement depuis les bords 41 et 42 de la coque mobile 4. En exerçant les efforts représentés par les flèches de la figure sur les protubérances, on peut modifier la position de la coque mobile jusqu'à ce que la coque mobile atteigne une position d'ouverture stable. Ainsi, l'application de forces sur les protubérances 7 ou 8, dont la ligne d'action ne passe pas par les pivots 5 ou 6, tout en maintenant la coque fixe en place, par exemple en son centre comme cela est représenté par la flèche s'y rattachant, décale la face d'obturation de sa position fermée stable. En poursuivant l'application de ces efforts, la coque mobile atteint une position de transition. Au-delà de cette position, la coque mobile va fléchir naturellement pour occuper une position ouverte stable.In Figure 5, we observe the shutter in the open position. The movable shell is then flexed into a second stable position. In this position, the shutter face 43 of the movable shell is spaced from the shutter face 33 of the fixed shell and thus frees the passage of the opening of the packaging. The rigidity of the shell 2 keeps the edges 41 and 42 at a spacing less than the length of material of the movable shell which joins them. Thus, the movable shell is forced into the stable open position. The shell 4 is then in a second stable position, in which its curvature is reversed relative to the closed position. As shown in FIG. 6, the passage from one position to the other can be obtained preferably by means of inversion of bending arranged on the movable shell. In the embodiment presented, these means correspond to the protrusions 7 and 8, extending laterally from the edges 41 and 42 of the movable shell 4. By exerting the forces represented by the arrows in the figure on the protrusions, it is possible to modify the position of the movable shell until the movable shell reaches a stable open position. Thus, the application of forces on the protrusions 7 or 8, the line of action of which does not pass through the pivots 5 or 6, while keeping the fixed shell in place, for example in its center as shown by the attached arrow, shifts the shutter face from its stable closed position. By continuing to apply these efforts, the mobile shell reaches a transition position. Beyond this position, the movable shell will flex naturally to occupy a stable open position.
On peut également utiliser d'autres moyens d'inversion de flexion que les protubérances 7 et 8. Selon la variante de l'emballage représenté en coupe à la figure 7, des languettes 13 et 14 sont solidarisées respectivement aux coques 3 et 4. Ces languettes peuvent être par exemple soudées ou collées sur les coques ou sur des zones des feuilles 9 et 10 solidaires des coques. Il suffit d'exercer un effort sur les languettes, comme représenté par les flèches, pour ouvrir l'obturateur. Ces languettes sont de préférence placées au niveau de la partie médiane des coques .One can also use other means of bending reversal than the protrusions 7 and 8. According to the variant of the packaging shown in section in Figure 7, the tongues 13 and 14 are secured respectively to the shells 3 and 4. These tabs can for example be welded or glued to the shells or to areas of the sheets 9 and 10 integral with the shells. It suffices to exert a force on the tabs, as represented by the arrows, to open the shutter. These tabs are preferably placed at the middle part of the shells.
La figure 8 présente une autre variante de moyens d'inversion de flexion. Des parties 15 et 16 ménagées dans les feuilles 10 et 9 respectivement font saillie par rapport aux coques de l'obturateur. Ainsi, il suffit d'exercer un effort sur les parties 15 et 16 pour ouvrir l'obturateur.FIG. 8 shows another variant of means for inverting bending. Parts 15 and 16 formed in the sheets 10 and 9 respectively protrude relative to the shells of the shutter. Thus, it suffices to exert a force on the parts 15 and 16 to open the shutter.
Le passage d'une position stable à l'autre peut également être obtenu en pressant les faces 33 et 43 des coques l'une contre l'autre pour la fermeture. Pour procéder à l'ouverture, il suffit d'écarter ces mêmes faces, en introduisant par exemple un objet entre ces faces, tel qu'une paille.The transition from a stable position to the other can also be obtained by pressing the faces 33 and 43 of the shells one against the other for closing. To proceed with opening, it is sufficient to separate these same faces, for example by introducing an object between these faces, such as a straw.
Les pivots 5 et 6 sont de préférence souples pour permettre un pivotement relatif des bords 31 et 32 par rapport aux bords 41 et 42 respectivement. Cette jonction peut être réalisée au moyen d'un joint de colle ou d'une soudure des coques à ce niveau. On peut également effectuer la jonction en solidarisant les coques 2 et 3 respectivement à deux faces d'un emballage, assemblées l'une à l'autre pour former les pivots entre les coques. Des procédés de fabrication de l'emballage seront détaillés par la suite. Les pivots peuvent avoir, au niveau de leur soudure, une forme de V.The pivots 5 and 6 are preferably flexible to allow relative pivoting of the edges 31 and 32 relative to the edges 41 and 42 respectively. This junction can be carried out by means of an adhesive joint or a welding of the shells at this level. It is also possible to join by joining the shells 2 and 3 respectively to two sides of a package, assembled together to form the pivots between the shells. Packaging manufacturing processes will be detailed later. The pivots may have, at their weld, a V shape.
Selon un autre mode de réalisation de l'invention, l'obturateur est réalisé en une pièce et comprend une coque mobile et une coque fixe. Ainsi, la coque mobile et la coque fixe sont réalisées monobloc. Une telle pièce peut notamment être obtenue par moulage ou par extrusion.According to another embodiment of the invention, the shutter is made in one piece and comprises a shell mobile and a fixed shell. Thus, the movable shell and the fixed shell are made in one piece. Such a part can in particular be obtained by molding or by extrusion.
La figure 9 représente un exemple d'obturateur selon ce mode de réalisation d'un emballage. Cet obturateur comprend une coque fixe 3 et une coque mobile 4 formées monobloc, en une seule et même pièce. On peut ainsi obtenir un obturateur monobloc en une seule pièce. La coque fixe et la coque mobile peuvent pivoter l'une par rapport à l'autre autour des pivots 5 et 6. La coque fixe présente une bande supérieure et une bande inférieure entourant une bande formant coque mobile. Lorsque l'obturateur est en position fermée, la coque mobile vient se caler entre la partie supérieure et la partie inférieure de la coque fixe. La coque fixe et la coque mobile peuvent ainsi être décalées l'une par rapport à l'autre sans se recouvrir. Lorsque la coque fixe présente un nombre de bandes supérieur à celui de la coque mobile, la coque fixe présente une rigidité supérieure à la coque mobile. Une première feuille est solidarisée sur la partie arrière (représentée par les hachures sur la figure) de la coque mobile 4. Une deuxième feuille est solidarisée sur la partie arrière de la coque fixe 3. L'obturateur est ainsi placé à l'intérieur de l'emballage. L'obturateur est représenté en position ouverte sur la figure 9; la coque mobile est en effet écartée de la coque fixe. Pour fermer l'obturateur, il suffit de presser la coque mobile en direction de la coque fixe. Lorsque la coque mobile se cale entre les deux parties de la coque fixe, les feuilles solidarisées respectivement à la coque mobile et à la coque fixe viennent en contact pour empêcher tout écoulement de fluide. Un tel obturateur peut être obtenu à partir d'une plaque dans laquelle on réalise deux découpes longitudinales pour délimiter la coque mobile et la coque fixe . On peut ensuite donner une concavité aux coques par formage par exemple . L'obturateur de la variante représentée à la figure 9 est formé monobloc mais on peut aussi envisager de réaliser cet obturateur sous forme de plusieurs coques mobiles et fixes indépendantes. On peut également prévoir que la coque mobile ou la coque fixe présente un nombre de parties différent . L'obturateur représenté à la figure 9 présente également des protubérances 7 et 8 mais d'autres moyens d'inversion de flexion de la partie mobile peuvent également être utilisés, tels que ceux représentés aux figures 7 et 8.FIG. 9 shows an example of a shutter according to this embodiment of a package. This shutter comprises a fixed shell 3 and a movable shell 4 formed in one piece, in one and the same piece. It is thus possible to obtain a one-piece shutter in one piece. The fixed shell and the movable shell can pivot relative to each other around the pivots 5 and 6. The fixed shell has an upper band and a lower band surrounding a band forming a movable shell. When the shutter is in the closed position, the movable shell is wedged between the upper part and the lower part of the fixed shell. The fixed shell and the movable shell can thus be offset with respect to each other without overlapping. When the fixed shell has a greater number of bands than that of the movable shell, the fixed shell has greater rigidity than the movable shell. A first sheet is secured to the rear part (represented by the hatching in the figure) of the movable shell 4. A second sheet is secured to the rear part of the fixed shell 3. The shutter is thus placed inside packaging. The shutter is shown in the open position in Figure 9; the movable shell is in fact moved away from the fixed shell. To close the shutter, simply press the movable shell towards the fixed shell. When the movable shell is wedged between the two parts of the fixed shell, the sheets secured respectively to the movable shell and to the fixed shell come into contact to prevent any flow of fluid. Such a shutter can be obtained from a plate in which two longitudinal cuts are made to delimit the movable shell and the fixed shell. One can then give a concavity to the shells by forming for example. The shutter of the variant shown in Figure 9 is formed in one piece, but one can also consider making this shutter in the form of several movable and fixed shells. independent. It can also be provided that the movable shell or the fixed shell has a different number of parts. The shutter shown in FIG. 9 also has protuberances 7 and 8, but other means of bending inversion of the mobile part can also be used, such as those shown in FIGS. 7 and 8.
Les figures 10 et 11 représentent en vue de dessus un autre mode de réalisation d'un emballage selon l'invention. Dans ce mode de réalisation, la coque mobile comporte deux parties articulées. La coque mobile présente de préférence une articulation 17 sensiblement vers son milieu. Dans ce mode de réalisation, la coque fixe est de préférence souple et les deux parties sont de préférence rigides. La coque mobile peut ainsi se rabattre contre la coque fixe pour fermer l'obturateur. Lorsqu'un utilisateur rapproche la coque mobile de la coque souple depuis la position ouverte de l'obturateur, les pivots sont écartés. Les deux parties de la coque mobile pivotent autour de l'articulation, et la coque fixe fléchit pour permettre l' ecartement des pivots. La coque mobile et la coque fixe sont respectivement solidaires des feuilles 9 et 10. L'articulation peut être réalisée dans la coque elle-même ou au moyen de la feuille 9.Figures 10 and 11 show a top view of another embodiment of a package according to the invention. In this embodiment, the movable shell has two articulated parts. The movable shell preferably has a hinge 17 substantially towards its middle. In this embodiment, the fixed shell is preferably flexible and the two parts are preferably rigid. The movable shell can thus be folded against the fixed shell to close the shutter. When a user brings the movable shell closer to the flexible shell from the open position of the shutter, the pivots are moved apart. The two parts of the movable shell pivot around the articulation, and the fixed shell flexes to allow the spacing of the pivots. The movable shell and the fixed shell are respectively integral with the sheets 9 and 10. The articulation can be carried out in the shell itself or by means of the sheet 9.
On utilise de préférence une coque mobile d'une rigidité supérieure à une valeur Rmin. Ainsi, la coque mobile ne présente que peu de positions stables de fléchissement. La coque mobile a alors tendance à revenir d'elle-même vers une des positions de fermeture ou d'ouverture lorsqu'elle est écartée d'une de celles-ci. De plus elle peut alors exercer une pression de fermeture sur la face d'obturation 33 assurant une bonne étanchéité de l'obturateur. Par ailleurs, on utilise de préférence une coque mobile d'une rigidité inférieure à une valeur Rmax. Ainsi, la coque mobile fléchit aisément lorsqu'elle est sollicitée par un utilisateur. La position ouverte de l'obturateur présente alors une section de passage optimale, et la position de fermeture de l'obturateur présente par ailleurs une étanchéité convenable. La rigidité d'une coque mobile se détermine également en fonction de la taille de la surface d'obturation 43.It is preferable to use a mobile shell with a rigidity greater than an Rmin value. Thus, the movable shell has only a few stable deflection positions. The movable shell then tends to return by itself to one of the closed or open positions when it is moved away from one of these. In addition, it can then exert closing pressure on the shutter face 33 ensuring good sealing of the shutter. Furthermore, it is preferable to use a movable shell with a rigidity of less than an Rmax value. Thus, the movable shell flexes easily when it is requested by a user. The open position of the shutter then has an optimal passage section, and the closed position of the shutter also has a suitable seal. The rigidity of a movable shell is also determined according to the size of the sealing surface 43.
La coque mobile peut être réalisée avec un matériau présentant un module de flexion E équivalent compris entre 700 et 5000 Mpa. Une épaisseur moyenne H comprise entre 8μm et 1mm convient. On utilise préférentiellement une coque mobile d'une épaisseur H comprise entre 50 et 500μm. Une hauteur de coque b comprise entre 1 et 50 mm convient. On utilise de préférence une hauteur de coque b comprise entre 3 et 20mm pour la coque mobile. Un produit bH3E, caractérisant la rigidité, compris entre Rmin=5 N.mm2 et Rmax=200000 N.mm2 pour la coque mobile convient. On utilise de préférence une coque mobile ayant un produit bH3E compris entre 35 et 50000 N.mm2.The movable shell can be made with a material having an equivalent flexural modulus E of between 700 and 5000 Mpa. An average thickness H of between 8 μm and 1 mm is suitable. Preferably, a mobile shell with a thickness H of between 50 and 500 μm is used. A hull height b between 1 and 50 mm is suitable. A hull height b preferably between 3 and 20mm is used for the movable hull. A bH 3 E product, characterizing the rigidity, between Rmin = 5 N.mm 2 and Rmax = 200000 N.mm 2 for the movable shell is suitable. Preferably, a mobile shell having a bH 3 E product of between 35 and 50,000 N.mm 2 is used .
Il est souhaitable de choisir une rigidité pour la coque 3 supérieure à la limite inférieure de rigidité R'min pour avoir une coque qui se déforme peu lorsqu'un utilisateur la manipule. On peut ainsi maintenir un ecartement entre les pivots sensiblement constant.It is desirable to choose a rigidity for the shell 3 greater than the lower stiffness limit R'min in order to have a shell which deforms little when a user handles it. It is thus possible to maintain a substantially constant spacing between the pivots.
La coque fixe peut ainsi être réalisée avec un matériau présentant un module de flexion E équivalent compris entre 700 et 5000 Mpa. Une épaisseur moyenne H comprise entre 20μm et 2mm convient. On utilise préférentiellement une coque fixe d'une épaisseur H comprise entre 100 et lOOOμm. On obtient ainsi un bon compromis entre la rigidité et la compacité de la coque. Une hauteur de coque b comprise entre 1 et 70 mm convient . On utilise de préférence une hauteur de coque b comprise entre 3 et 30mm pour la coque mobile. Un produit bH3E compris entre 50 et 5000000 N.mm2 pour la coque fixe convient. On utilise de préférence une coque ayant un produit bH3E compris entre 200 et 500000 N.mm2.The fixed shell can thus be produced with a material having an equivalent flexural modulus E of between 700 and 5000 Mpa. An average thickness H of between 20 μm and 2 mm is suitable. Preferably, a fixed shell with a thickness H of between 100 and 100 μm is used. A good compromise is thus obtained between the rigidity and the compactness of the hull. A hull height b between 1 and 70 mm is suitable. A hull height b of between 3 and 30 mm is preferably used for the movable hull. A bH 3 E product between 50 and 5,000,000 N.mm 2 for the fixed shell is suitable. A shell is preferably used having a product bH 3 E of between 200 and 500,000 N.mm 2 .
Il est cependant préférable que le produit bH3E de la coque mobile soit inférieur ou égal à celui de la coque fixe. On choisira ainsi de préférence un rapport R entre les rigidités compris entre 1:1000 et 1:1. La coque fixe ne fléchira dans ce cas qu'assez peu lors de la déformation de la coque mobile. Il est préférable que la distance D entre les pivots 5 et 6 soit comprise entre 2 mm et la largeur de l'emballage, et plus particulièrement entre 5 et 50 mm.It is however preferable that the product bH 3 E of the mobile shell is less than or equal to that of the fixed shell. A ratio R between the rigidities of between 1: 1000 and 1: 1 will therefore preferably be chosen. In this case, the fixed shell will only flex relatively little during the deformation of the mobile shell. It is preferable that the distance D between the pivots 5 and 6 is between 2 mm and the width of the packaging, and more particularly between 5 and 50 mm.
D'une façon générale, il est préférable d'utiliser uneIn general, it is better to use a
5 coque fixe et une coque mobile dont les longueurs développées entre pivots sont similaires. On choisira ainsi de préférence un rapport de la longueur développée de la coque mobile sur la longueur développée de la coque fixe compris entre 0,9 et 1,1.5 fixed hull and a movable hull whose lengths developed between pivots are similar. A ratio of the developed length of the movable shell to the developed length of the fixed shell is therefore preferably chosen to be between 0.9 and 1.1.
En désignant par d la distance entre articulations, onBy designating by d the distance between joints, we
10 choisit par ailleurs de préférence une longueur développée entre pivot comprise entre D et π*D/2, et plus particulièrement entre"*" *D/8 et π*D/2. La coque mobile peut alors présenter deux positions stables: une position stable de part et d'autre du plan défini par les pivots. Ainsi, lorsque les deux coques10 preferably also chooses a developed length between pivot between D and π * D / 2, and more particularly between " *" * D / 8 and π * D / 2. The movable shell can then have two stable positions: a stable position on either side of the plane defined by the pivots. So when the two hulls
15 sont du même côté de ce plan, l'obturateur est fermé. Lorsque les coques sont de part et d'autre de ce plan, l'obturateur est ouvert .15 are on the same side of this plane, the shutter is closed. When the shells are on either side of this plane, the shutter is open.
On peut utiliser des matériaux tels que le PE, le PVC, le PMMA, l'EVA, le PP, l'OPP, le PET, le polycarbonate, le PA, le 20 carton, l'acier ou l'aluminium pour réaliser les coques. Les coques peuvent se présenter sous la forme de films mono ou multicouches ou de pièce injectée. Elles peuvent par exemple être obtenues par emboutissage, formage à chaud, injection ou thermoformage . 25 L'homme de métier saura trouver en fonction des valeurs de b, D, H, E, H3E et R définir les matériaux et les épaisseurs appropriées .Materials such as PE, PVC, PMMA, EVA, PP, OPP, PET, polycarbonate, PA, cardboard, steel or aluminum can be used to make the materials. shells. The shells can be in the form of single or multi-layer films or of injected part. They can for example be obtained by stamping, hot forming, injection or thermoforming. The skilled person will be able to find, as a function of the values of b, D, H, E, H3E and R, define the appropriate materials and thicknesses.
Enfin, on notera que les feuilles et films peuvent comprendre les additifs classiques, et être constitués deFinally, it should be noted that the sheets and films can comprise the conventional additives, and be made up of
30 plusieurs couches, comme il est connu dans l'art. Ainsi, les films ou feuilles peuvent comprendre plusieurs couches, dont l'une est soudable.30 multiple layers, as is known in the art. Thus, the films or sheets can comprise several layers, one of which is weldable.
Selon une variante de l'invention, une des feuilles de l'emballage est rattachée à la coque fixe et fait office de 35. coque mobile.According to a variant of the invention, one of the sheets of the packaging is attached to the fixed shell and acts as a 35 . movable shell.
Selon encore une variante de l'invention, la coque mobile est rapportée sur une feuille de l'emballage. Il est également possible de réaliser l'emballage et l'obturateur monobloc, en une seule et même pièce. Il est également possible de réaliser l'obturateur et l'une des coques monobloc, en une seule et même pièce. Cet obturateur peut aussi comprendre des dispositifs supplémentaires d' étanchéité tels que ceux connus dans l'état de la technique, pour parfaire 1 ' étanchéité .According to another variant of the invention, the movable shell is attached to a sheet of the packaging. It is also possible to make the packaging and the one-piece shutter, in one and the same piece. It is also possible to make the shutter and one of the one-piece shells, in a single piece. This shutter can also include additional sealing devices such as those known in the state of the art, to complete one seal.
Ainsi, suivant un autre mode de réalisation, un opercule déchirable est disposé sur l'extrémité de l'obturateur. Cet opercule peut permettre d'assurer une étanchéité parfaite de l'obturateur avant l'utilisation de l'emballage. Cet opercule peut ainsi assurer 1 ' inviolabilité et la sécurité de l'emballage. Cet opercule peut être réalisé par exemple par une soudure des feuilles de l'emballage au-dessus de l'obturateur. Cet opercule déchirable peut par exemple permettre de maintenir un emballage stérile ou sous vide avant qu'il ne soit ouvert par un utilisateur. Cet opercule peut aussi comprendre un film pelable de préférence repositionnable . L'invention concerne également des procédés de fabrication d'un emballage 1.Thus, according to another embodiment, a tearable lid is disposed on the end of the shutter. This seal can help ensure a perfect seal of the shutter before using the packaging. This seal can thus ensure inviolability and security of the packaging. This cover can be produced for example by welding the sheets of the packaging above the shutter. This tearable lid can for example allow to maintain a sterile or vacuum packaging before it is opened by a user. This cover may also include a peelable film, preferably repositionable. The invention also relates to methods of manufacturing a package 1.
La' figure 12 représente les étapes d'un procédé de fabrication d'un emballage selon l'invention. Ce procédé comprend l'étape 101, qui consiste à assembler deux feuilles 9 et 10, en les superposant et en réalisant une soudure 11. Cette soudure 11 ménage une ouverture dans l'emballage. La soudure 11 définit deux pivots 5 et 6 au niveau de 1 ' ouverture .Figure 12 shows the steps of a method of manufacturing a package according to the invention. This method comprises step 101, which consists in assembling two sheets 9 and 10, by superimposing them and by carrying out a seal 11. This seal 11 provides an opening in the packaging. The weld 11 defines two pivots 5 and 6 at the opening.
Par ailleurs, à l'étape 102, on encolle une coque mobile plane 4 au moins sur sa face d'obturation 43 et on encolle une coque concave fixe 3 sur sa face d'obturation 33. On peut à cette étape délimiter les bords 41 et 42 en n'encollant que la face d'obturation 43.Furthermore, in step 102, a planar movable shell 4 is bonded at least on its sealing face 43 and a fixed concave shell 3 is bonded to its sealing face 33. It is possible at this step to define the edges 41 and 42 by gluing only the sealing face 43.
A l'étape 103, on fixe les coques sur les faces extérieures des feuilles assemblées. On applique la face d'obturation 33 encollée de la coque fixe 3 sμr la feuille 10 au niveau de l'ouverture. Les bords 31 et 32 sont mis en correspondance avec les pivots de soudure 5 et 6. On applique également la face d'obturation 43 de la coque mobile 4 sur la feuille 9 au niveau de l'ouverture. Les bords 41 et 42 sont mis en correspondance avec les pivots de soudure 5 et 6. On peut presser les faces d'obturation l'une contre l'autre afin d'améliorer le collage et donner une forme concave à la coque mobile 4 de courbure identique à la courbure de la coque fixe concave 3.In step 103, the shells are fixed to the outer faces of the assembled sheets. Apply the sealing face 33 bonded to the fixed shell 3 on the sheet 10 at the opening. Edges 31 and 32 are matched with the welding pivots 5 and 6. The sealing face 43 of the movable shell 4 is also applied to the sheet 9 at the opening. The edges 41 and 42 are matched with the welding pivots 5 and 6. The closure faces can be pressed against one another in order to improve the bonding and give a concave shape to the movable shell 4 of curvature identical to the curvature of the concave fixed shell 3.
Un autre procédé permet de placer les coques à l'intérieur de l'emballage. Pour cela, on encolle les faces opposées aux faces d'obturation 33 et 43 des coques 3 et 4. On peut comme dans le procédé précédant délimiter les bords 41 et 42 en n'encollant que la face opposée à la face d'obturation 43. On fixe alors les coques sur les faces intérieures des feuilles assemblées.Another method makes it possible to place the shells inside the packaging. For this, the faces opposite the sealing faces 33 and 43 of the shells 3 and 4 are glued. As in the preceding process, it is possible to define the edges 41 and 42 by gluing only the face opposite to the sealing face 43. The shells are then fixed on the interior faces of the assembled sheets.
Selon un autre procédé, on assemble une première et une deuxième feuille en ménageant une ouverture, puis on rapporte une coque fixe concave. On aplatit ensuite élastiquement la coque concave, puis on l'assemble au niveau de l'ouverture sur une des deux feuilles. La coque fixe retourne alors à sa position concave d'origine.According to another method, a first and a second sheet are assembled with an opening, then a concave fixed shell is attached. The concave shell is then flattened elastically, then assembled at the opening on one of the two sheets. The fixed shell then returns to its original concave position.
Selon encore un autre procédé de fabrication d'un emballage selon 1 ' invention, une coque fixe plane est rapportée sur ou formée dans une feuille de l'emballage, puis concave selon un procédé connu .According to yet another method of manufacturing a package according to the invention, a flat fixed shell is attached to or formed in a sheet of the package, then concave according to a known method.
Il est également envisageable de réaliser l'assemblage des coques sur les feuille par soudage. Il est encore possible d'assembler les feuilles par collage.It is also possible to carry out the assembly of the shells on the sheets by welding. It is still possible to assemble the sheets by gluing.
La fabrication peut par ailleurs faire emploi d'un film- écran qui permet une soudure d'une des feuilles sur l'autre en ménageant une ouverture au niveau de 1 ' obturateur . On introduit un film formant écran sur une feuille au niveau de l'ouverture à ménager. On vient ensuite apposer l'autre feuille sur la structure précédente, et on place le tout entre deux mâchoires d'une machine à souder ou barrettes de soudure. Ce film formant écran est en un matériau sensiblement insensible à la chaleur et qui n'adhère pas sur le film à la température de soudure. Il peut être par exemple en PTFE, ou en un autre matériau, tel que de la toile téflonnée. Dans ce cas on peut souder en même temps les feuilles et la coque fixe, ou les feuilles et les coques fixes et mobiles. On notera que les procédés ci-dessus s'appliquent sans modification majeure au cas où l'une des feuilles de l'emballage sert de coque mobile.Manufacturing can also make use of a screen film which allows a weld of one of the sheets on the other by providing an opening at the shutter. A film forming a screen is introduced on a sheet at the opening to be provided. We then affix the other sheet on the previous structure, and place everything between two jaws of a welding machine or solder bars. This screen film is made of a material which is substantially insensitive to heat and which does not adhere to the film upon solder temperature. It may for example be made of PTFE, or of another material, such as teflon-coated fabric. In this case, the sheets and the fixed shell can be welded at the same time, or the sheets and the fixed and movable shells. It will be noted that the above methods apply without major modification in the case where one of the sheets of the packaging serves as a movable shell.
L'invention n'est pas limitée au mode de réalisation représenté mais est susceptible de nombreuses améliorations aisément accessibles à l'homme de l'art. Ainsi, un emballage présentant un obturateur dont la seule position stable se trouve en position fermée reste dans la portée de l'invention. Par ailleurs, bien que les coques concaves aient été principalement décrites avec une forme courbe continue, une coque présentant une forme discontinue, telle qu'une forme en V, reste dans la portée de l'invention. The invention is not limited to the embodiment shown but is capable of numerous improvements easily accessible to those skilled in the art. Thus, a package having a shutter whose only stable position is in the closed position remains within the scope of the invention. Furthermore, although the concave shells have been mainly described with a continuous curved shape, a hull having a discontinuous shape, such as a V shape, remains within the scope of the invention.
