Description

EMBALLAGE RENFORCE POUR PRODUITS POUVANT S'ECOULER REINFORCED PACKAGING FOR FLOWABLE PRODUCTS
La présente invention concerne le dispositif d'emballage et de conditionnement Plus particulièrement, l'invention concerne un dispositif de conditionnement de produits qui, ne se présentant pas sous la forme d'un bloc solide unique, peuvent s'écouler Ces produits peuvent être par exemple pâteux, granuleux ou liquidesThe present invention relates to the packaging and conditioning device More particularly, the invention relates to a device for packaging products which, not being in the form of a single solid block, can flow These products can be by example pasty, grainy or liquid
On connaît de nombreux dispositifs de conditionnement de tels produits On peut en classer les principaux types utilisés en deux familles principales • les dispositifs rigides (boîtes de conserve, bouteilles, bidons, canettes de boisson ) Les dispositifs de ce type sont très répandus mais ont l'inconvénient de présenter, lorsqu'ils sont vidés de leur contenu, le même encombrement que lorsqu'ils sont pleins De plus, le prix de revient de ces dispositifs qui sont souvent réalisés en acier ou en aluminium est relativement élevé,Numerous devices for packaging such products are known. The main types used can be classified into two main families • rigid devices (cans, bottles, cans, drink cans) Devices of this type are very widespread but have the disadvantage of having, when emptied of their contents, the same size as when they are full Furthermore, the cost price of these devices which are often made of steel or aluminum is relatively high,
• les dispositifs souples (pochons en particulier), généralement formés de l'assemblage étanche (par exemple par soudage) de deux feuilles souples réalisées à base de matériau plastique De tels pochons sont couramment utilisés par exemple pour le conditionnement de nourriture (aliments pour animaux, biscuits apéritifs) ou de liquides (lessive liquide notamment) En fonction de la nature du produit à conditionner, la composition des feuilles du pochon peut varier par exemple, pour le conditionnement de nourriture pour animaux qui doit être préservée des infiltrations de l'atmosphère extérieure, ces feuilles sont réalisées en intercalant une couche d'un matériau étanche (tel que l'aluminium) entre deux couches de matériau plastique qui assurent la tenue mécanique du pochon La surface extérieure de ces pochons est généralement imprimée pour afficher des informations de présentation et de promotion du produit Parmi les types de dispositifs de conditionnement évoqués ci-dessus, les pochons constituent un conditionnement simple et économique qui présente en outre l'avantage d'avoir un faible encombrement une fois vidé de son contenu, ce qui est avantageux du point de vue pratique• flexible devices (pouches in particular), generally formed by the sealed assembly (for example by welding) of two flexible sheets made from plastic material Such pouches are commonly used for example for the packaging of food (animal feed , aperitif cookies) or liquids (liquid detergent in particular) Depending on the nature of the product to be packaged, the composition of the leaves of the pouch can vary, for example, for the packaging of animal food which must be preserved from infiltration of the atmosphere outer, these sheets are made by inserting a layer of a waterproof material (such as aluminum) between two layers of plastic material which ensure the mechanical strength of the pouch The outer surface of these pouches is generally printed to display presentation information and product promotion Among the types of packaging devices ev hidden above, the pouches constitute a simple and economical packaging which also has the advantage of having a small footprint once emptied of its content, which is advantageous from a practical point of view
Cependant, les pochons comportent également certains inconvénientsHowever, the pouches also have certain disadvantages
• tout d'abord, une fois le pochon ouvert, en général par découpage de sa partie supérieure (à l'aide de ciseaux, ou à la main en suivant des lignes de fragilisation du pochon prévues à cet effet), la souplesse des feuilles constituant le pochon peut rendre malaisée la manipulation de ce dernier En particulier, il peut être délicat de maintenir le pochon ouvert et de verser correctement son contenu, les deux feuilles opposées ayant tendance à se vriller,• first of all, once the pouch is open, generally by cutting its upper part (using scissors, or by hand following the weakening lines of the pouch provided for this purpose), the flexibility of the sheets constituting the pouch can make it difficult to handle the latter In particular, it can be difficult to keep the pouch open and to pour its contents correctly, the two opposite sheets having a tendency to twist,
• deuxièmement, la souplesse du pochon fait qu'il a tendance à s'affaisser sur lui-même, ce qui complique le stockage et la présentation de ces pochons, en particulier dans les rayons des magasins où on recherche une présentation avantageuse du produit, • troisièmement, dans certains cas l'utilisateur peut ressentir de manière négative un contact trop « direct » de la main avec le contenu du pochon (en particulier dans le cas de nourriture pour animaux qui peut comporter des morceaux solides noyés dans un mélange fluide ou visqueux), • quatrièmement, l'impression graphique sur la surface externe du pochon nécessite souvent des temps importants de mise au point des machines d'impression, ce qui augmente le prix de revient unitaire des pochonsSecondly, the flexibility of the pouch means that it tends to collapse on itself, which complicates the storage and presentation of these pouches, in particular on the shelves of stores where an advantageous presentation of the product is sought, • thirdly, in certain cases the user may feel in a negative way too “direct” contact of the hand with the contents of the pouch (in particular in the case of animal feed which may include solid pieces embedded in a fluid mixture or viscous), • fourthly, the graphic printing on the external surface of the pouch often requires long development times of the printing machines, which increases the unit cost price of the pouches
• Enfin, les dispositifs connus ne comportent en général qu'un pochon unique Le but de l'invention est de permettre de réaliser un conditionnement mettant en œuvre un pochon, affranchi des inconvénients cités ci-dessus inhérents aux pochons connus• Finally, known devices generally only have a single pouch. The object of the invention is to make it possible to produce packaging using a pouch, free from the drawbacks mentioned above inherent in known pouches.
Afin d'atteindre ce but, l'invention propose un dispositif de conditionnement de produits pouvant s'écouler, comprenant au moins un pochon souple qui est de forme généralement aplatie et qui possède deux parois opposées en forme de feuille s'étendant sensiblement parallèlement à un plan longitudinal médian du dispositif, dispositif caractérisé en ce qu'il consiste enIn order to achieve this object, the invention provides a device for packaging flowable products, comprising at least one flexible pouch which is generally flattened in shape and which has two opposite sheet-like walls extending substantially parallel to a median longitudinal plane of the device, device characterized in that it consists of

En référence à la figure 1a, on a représenté un pochon 10 contenant un produit tel que, par exemple et de manière non limitative, de la nourriture (par exemple pour animaux) ou encore une lessive liquide Ce pochon est constitué de l'assemblage de deux feuilles souples 11 et 12 soudées bord à bord, par exemple par soudage à ultrasons Ce type de pochon peut être de type connu et ne sera pas décrit plus en détails Par convention, on définit le plan P longitudinal médian du dispositif (qui dans cette forme de réalisation dans laquelle le dispositif ne comprend qu'un pochon unique correspond également au plan longitudinal médian du pochon 10)Referring to Figure 1a, there is shown a pouch 10 containing a product such as, for example and without limitation, food (for example for animals) or liquid detergent This pouch consists of the assembly of two flexible sheets 11 and 12 welded edge to edge, for example by ultrasonic welding This type of pouch can be of known type and will not be described in more detail By convention, the median longitudinal plane P of the device is defined (which in this embodiment in which the device comprises only a single pouch also corresponds to the median longitudinal plane of the pouch 10)
Selon l'invention, deux éléments de renfort 21 et 22 sont collés sur les deux faces opposées du pochon, en regard l'une de l'autre Ces éléments de renfort sont réalisés dans un matériau relativement rigide mais ayant une flexibilité suffisante pour pouvoir être déformé par la main d'un utilisateur, on pourra par exemple réaliser les éléments de renfort 21 et 22 en cartonAccording to the invention, two reinforcing elements 21 and 22 are bonded to the two opposite faces of the pouch, facing one another. These reinforcing elements are made of a relatively rigid material but having sufficient flexibility to be able to be deformed by the hand of a user, we can for example make the reinforcing elements 21 and 22 in cardboard
Dans les formes de réalisation représentées sur les dessins, chaque élément de renfort 21 ou 22 est réalise sous la forme d'une feuille (en carton ou autre) ne comportant aucun aménagement spécifique pour guider sa déformation suite au rapprochement de ses deux extrémités latérales par la main d'un utilisateur, de sorte que cette déformation correspond à une cambrure de l'élément de renfortIn the embodiments shown in the drawings, each reinforcing element 21 or 22 is produced in the form of a sheet (cardboard or other) having no specific arrangement to guide its deformation following the bringing together of its two lateral ends by the hand of a user, so that this deformation corresponds to a camber of the reinforcing element
Il est toutefois également possible de prévoir dans chaque élément de renfort une ligne de fragilisation et/ou de pliure (par exemple sensiblement verticale) de sorte que suite au rapprochement de ses deux extrémités latérales, chaque élément de renfort se plie en deux à la manière d'un volet articulé, les parties médianes des deux éléments de renfort s'écartant toujours l'une de l'autre dans ce cas Les éléments de renfort 21 et 22 s'étendent comme représenté sur la figure 1 b sur toute la largeur du pochon, dont ils débordent des deux côtés Comme représenté sur les figures 2a et 2b (sur lesquelles l'extrémité haute du pochon a été déchirée pour accéder à son contenu), un utilisateur peut, en sollicitant les extrémités des éléments de renfort 21 et 22 pour les rapprocher, déformer ces éléments de renfort flexibles en les cambrant et en écartant leurs parties médianes respectives Par souci de clarté, la main de l'utilisateur est représentée seulement sur la figure 2aIt is however also possible to provide in each reinforcement element a line of embrittlement and / or fold (for example substantially vertical) so that following the bringing together of its two lateral ends, each reinforcement element folds in half in the manner of an articulated flap, the middle parts of the two reinforcing elements always deviating from one another in this case The reinforcing elements 21 and 22 extend as shown in FIG. 1b over the entire width of the pouch, which they overflow on both sides As shown in FIGS. 2a and 2b (in which the upper end of the pouch has been torn in order to access its contents), a user can, by urging the ends of the reinforcing elements 21 and 22 to bring them together, deform these elements. flexible reinforcement by arching them and spreading their respective median parts For the sake of clarity, the user's hand is shown only in FIG. 2a
Les deux parois opposées 11 , 12 du pochon étant respectivement collées aux deux éléments de renfort 21 et 22 dans leur région médiane, cet écartement provoque une ouverture contrôlée du pochon, après que l'extrémité haute de celui-ci ait été déchiré II est alors possible de manipuler le dispositif de conditionnement de manière fiable, et en particulier de procéder de manière efficace au déversement du produit contenuThe two opposite walls 11, 12 of the pouch being respectively glued to the two reinforcing elements 21 and 22 in their median region, this spacing causes a controlled opening of the pouch, after the upper end of the latter has been torn II is then possible to handle the packaging device reliably, and in particular to efficiently discharge the contained product
Il est important de noter ICI que le collage des éléments de renfort 21 et 22 sur les parois du pochon peut être réalisé par une bande de colle continue couvrant tout ou partie de la largeur de la paroi du pochon, ou par l'application en des endroits discrets de points de collage (par exemple en déposant sur chaque paroi du pochon un point de collage en son milieu, entouré de deux points de collage latéraux) Dans tous les cas de figure, il est important selon l'invention que au moins la région médiane de chaque paroi du pochon soit collée a l'élément de renfort associéIt is important to note HERE that the bonding of the reinforcing elements 21 and 22 on the walls of the pouch can be carried out by a strip of continuous adhesive covering all or part of the width of the wall of the pouch, or by the application in discrete locations of bonding points (for example by depositing on each wall of the pouch a bonding point in the middle, surrounded by two lateral bonding points) In all cases, it is important according to the invention that at least the middle region of each wall of the pouch is glued to the associated reinforcement element
En outre, on procédera avantageusement au collage de chaque élément de renfort à sa paroi de pochon associée également au niveau des deux bords latéraux du pochon, afin d'augmenter la cohérence de l'ensemble et de faciliter encore l'ouverture du pochonIn addition, each bonding element will advantageously be bonded to its pouch wall, also associated at the two lateral edges of the pouch, in order to increase the coherence of the assembly and further facilitate the opening of the pouch.
Grâce au collage des deux éléments de renfort 21 et 22 sur les parois opposées du pochon, on fiabilise ainsi la manipulation et l'utilisation du pochonThanks to the bonding of the two reinforcing elements 21 and 22 on the opposite walls of the pouch, the handling and the use of the pouch are made more reliable.
On choisira de préférence le matériau de ces éléments de renfort 21 et 22 avec une élasticité suffisante pour qu'après plusieurs manipulations d'ouverture, ces éléments de renfort retrouvent naturellement leur forme originale correspondant à la figure 2aThe material of these reinforcing elements 21 and 22 will preferably be chosen with sufficient elasticity so that after several manipulations these reinforcement elements naturally regain their original shape corresponding to FIG. 2a
La figure 3a montre une vue de dessus schématique d'un pochon 10 entouré de deux éléments de renfort 21 et 22 qui lui sont collés , sur cette figure, on constate que les deux éléments de renfort 21 et 22 sont disjoints, alors que sur la figure 3b qui est une représentation similaire d'un mode de réalisation alternatif, les extrémités des deux éléments de renfort 21 et 22 sont réunies II est ainsi possible d'associer au pochon des éléments de renfort 21 et 22 sous la forme de deux bandes flexibles distinctes, ou bien d'un fourreau unique entourant le pochon sans discontinuitéFIG. 3a shows a schematic top view of a pouch 10 surrounded by two reinforcing elements 21 and 22 which are glued to it, in this figure, it can be seen that the two reinforcing elements 21 and 22 are disjointed, while on the Figure 3b which is a similar representation of an alternative embodiment, the ends of the two reinforcing elements 21 and 22 are joined together It is thus possible to associate the pouch with reinforcing elements 21 and 22 in the form of two flexible bands separate, or a single sheath surrounding the pouch without discontinuity
Les figures 4a à 4c montrent trois variantes de réalisation, pouvant être mises en œuvre avec chacune des deux modes de réalisation représentés sur les figures 3a et 3bFigures 4a to 4c show three alternative embodiments, which can be implemented with each of the two embodiments shown in Figures 3a and 3b
Sur la figure 4a, les extrémités inférieures des éléments de renfort 21 et 22 sont situées en-dessous du pochon et sont réunies par une base 23 horizontale venue de matière avec ces éléments de renfort Cette variante de réalisation permet de munir le dispositif d'une base stable et de remédier ainsi à l'inconvénient d'instabilité des pochons mentionné en introduction de ce texte On notera également que le fait de recouvrir la surface du pochon par l'armature semi-rigide formée des éléments de renfort 21 et 22 sur toute sa hauteur permet d'offrir à la main de l'utilisateur un contact plus « lisse » que celui du pochon « brut », ce qui peut être recherché pour certains produitsIn FIG. 4a, the lower ends of the reinforcing elements 21 and 22 are located below the pouch and are joined by a horizontal base 23 made integrally with these reinforcing elements. This alternative embodiment makes it possible to provide the device with a stable base and thus remedy the drawback of instability of the pouches mentioned in the introduction to this text. It will also be noted that the fact of covering the surface of the pouch with the semi-rigid reinforcement formed of reinforcing elements 21 and 22 over all its height makes it possible to offer a “smoother” contact to the user's hand than that of the “raw” pouch, which can be sought for certain products
Sur la figure 4b, les éléments de renfort 21 et 22 s'étendent sur toute la hauteur du pochon, mais leurs extrémités inférieures sont disjointes cette variante correspond au cas où le pochon est simplement « pris en sandwich » entre deux flancs flexibles (mode de réalisation de la figure 3a), ou entouré d'un fourreau ouvert à ses deux extrémités, et aux parois desquelles le pochon est collé (mode de réalisation de la figure 3b) Sur la figure 4c, les deux éléments de renfort 21 et 22 ont des extrémités basses disjointes mais leur extrémité haute est recouverte par une partie 24 venue de matièreIn FIG. 4b, the reinforcing elements 21 and 22 extend over the entire height of the pouch, but their lower ends are disjointed. This variant corresponds to the case where the pouch is simply "sandwiched" between two flexible sides (mode of embodiment of FIG. 3a), or surrounded by a sheath open at its two ends, and to the walls of which the pouch is glued (embodiment of FIG. 3b) In FIG. 4c, the two reinforcing elements 21 and 22 have disjointed lower ends but their upper end is covered by a part 24 made of material
Il est possible selon l'invention d'entourer complètement le pochon par un cartonnage comportant une base et un sommetIt is possible according to the invention to completely surround the pouch with a carton comprising a base and a top
Il est également possible de prévoir dans les éléments de renfort 21 et 22 des plis des soufflets ou des découpes, afin de rendre possible la manipulation décrite en référence aux figures 2a et 2b même en la présence d'une base et/ou d'un sommet relativement rigides La fonction principale des éléments de renfort 21 et 22 est, comme on l'a dit, de permettre une ouverture fiable du pochon Ces éléments présentent également l'avantage de pouvoir être utilisés comme surface graphique pour présenter des informations sur le produit ou des données de promotion A cet égard, on notera que l'impression sur une matière telle que le carton nécessite un temps de réglage des machines sensiblement inférieur par rapport aux films synthétiques qui constituent habituellement les pochons connus , il est ainsi possible, en particulier dans le cas où les éléments de renfort 21 et 22 s'étendent sur toute la hauteur du pochon, de ne pas imprimer la paroi du pochon, mais seulement les éléments de renfort qui l'entourent On notera en outre qu'il est possible d'imprimer les deux faces de chaque élément de renfort 21 et 22, ce qui augmente considérablement la surface graphiquement exploitable du dispositifIt is also possible to provide in the reinforcing elements 21 and 22 folds of bellows or cutouts, in order to make possible the manipulation described with reference to FIGS. 2a and 2b even in the presence of a base and / or a relatively rigid top The main function of the reinforcing elements 21 and 22 is, as we have said, to allow a reliable opening of the pouch These elements also have the advantage of being able to be used as graphic surface for presenting information on the product or promotional data In this regard, it will be noted that printing on a material such as cardboard requires a significantly shorter machine setting time compared to the synthetic films which usually constitute known pouches, it is thus possible, in particular in the case where the reinforcing elements 21 and 22 extend over the entire height of the pouch, not to print the wall of the pouch, but only the reinforcing elements which surround it It will further be noted that it is possible to print the two faces of each reinforcing element 21 and 22, which considerably increases the graphically exploitable surface of the device
Les figures 5a et 5b représentent un dispositif de conditionnement selon l'invention, correspondant aux configurations des figures 3b et 4b (extrémités latérales des éléments de renfort au moins ponctuellement reunies et extrémités inférieures de ces éléments de renfort réunies par une base) On constate que les éléments de renfort ont été ici découpés de manière à avoir un aspect caractéristique (tête de chat) , il s'agit ici en l'occurrence d'un dispositif contenant de la nourriture pour chats Chacun des deux coins supérieurs de l'élément de renfort (qui correspond à une oreille du chat) est collé au coin de l'élément de renfort se trouvant en regard, pour augmenter la rigidité du dispositifFIGS. 5a and 5b represent a packaging device according to the invention, corresponding to the configurations of FIGS. 3b and 4b (lateral ends of the reinforcement elements at least punctually joined together and lower ends of these reinforcement elements joined by a base) It can be seen that the reinforcing elements have been cut out here so as to have a characteristic appearance (cat head), in this case it is a device containing cat food Each of the two upper corners of the reinforcement (which corresponds to a cat's ear) is glued to the corner of the reinforcement element facing it, to increase the rigidity of the device
On remarquera sur ces figures qu'il est possible d'intégrer entre la base du cartonnage et le pochon un élément tel qu'un objet promotionnel ou publicitaire 30 On remarquera également que le fait, dans cette variante, de ne pas fermer complètement la structure de renfort du pochon permet à l'utilisateur de toucher directement le pochon et de sentir tactilement le produit contenu , en fonction de la nature du produit et du positionnement marketing souhaité, on pourra ainsi choisir une structure de renfort plus ou moins ouverte, pour offrir un accès plus ou moins direct au produitIt will be noted in these figures that it is possible to integrate between the base of the carton and the pouch an element such as a promotional or advertising object 30 It will also be noted that the fact, in this variant, of not completely closing the structure reinforcement of the pouch allows the user to directly touch the pouch and to tactilely feel the product contained, depending on the nature of the product and the desired marketing positioning, we can thus choose a more or less open reinforcement structure, to offer more or less direct access to the product
Les figures 6a à 6d sont quatre représentations du pochon des figures 5a et 5b une fois que le haut du pochon a été découpéFigures 6a to 6d are four representations of the pouch of Figures 5a and 5b once the top of the pouch has been cut
Sur la figure 6a, on constate qu'une partie de l'élément 21 a été elle- même découpée pour constituer une languette 210 pouvant être redressée et rabattue sur le sommet du pochon, et être engagée dans une fente 220 de l'élément de renfort 22 opposé (figure 6b) Selon le mode de réalisation représenté, en particulier sur la figure 6a, on constate qu'en découpant la languette 210 dans l'élément 21 on a défini une ouverture 211 pour faciliter la manipulation de la languette Les figures 6c et 6d représentent les deux faces du dispositif une fois la languette engagée dans la fente Cette disposition permet de refermer le pochon lorsque seule une partie de son contenu a été déverséeIn FIG. 6a, it can be seen that part of the element 21 has itself been cut to form a tongue 210 which can be straightened and folded over the top of the pouch, and be engaged in a slot 220 of the element reinforcement 22 opposite (FIG. 6b) According to the embodiment shown, in particular in FIG. 6a, it can be seen that by cutting the tongue 210 in the element 21, an opening 211 has been defined to facilitate the manipulation of the tongue. The figures 6c and 6d represent the two sides of the device once the tongue is engaged in the slot. This arrangement allows the pouch to be closed when only part of its contents has been spilled.
On notera que le dispositif de conditionnement selon l'invention peut être réalisé dans des tailles diverses , en particulier il est possible de prévoir des dispositifs de grande dimension que l'on manipule avec les deux mains pour écarter les deux éléments de renfort et ouvrir le pochon (application par exemple au conditionnement d'aliments pour chiens)It will be noted that the packaging device according to the invention can be produced in various sizes, in particular it is possible to provide large devices that are manipulated with both hands to separate the two reinforcing elements and open the pouch (application for example to the packaging of dog food)
Avantageusement selon l'invention, il est possible de prévoir sur chacun des éléments de renfort une ligne prédécoupée d'arrachage, référencée L sur les figures 7a à 7c, à la même hauteur que le collage de ces éléments de renfort 21 ' et 22' sur le pochon De préférence, on déposera dans ce cas entre chaque élément de renfort et sa face de pochon associée de la colle selon deux lignes C continues qui apparaissent sur les figures 7b et 7c, et qui s'étendent sensiblement d'un bord latéral à l'autre de leur face du pochon associée, parallèlement à leur ligne L d'arrachage associée, ladite ligne d'arrachage étant intercalée selon la direction verticale entre les deux lignes de colle CAdvantageously according to the invention, it is possible to provide on each of the reinforcement elements a precut tear line, referenced L in FIGS. 7a to 7c, at the same height as the bonding of these reinforcement elements 21 ′ and 22 ′ on the pouch Preferably, in this case, glue will be deposited between each reinforcing element and its associated pouch face along two continuous lines C which appear in FIGS. 7b and 7c, and which extend substantially from one side edge to the other of their face of the associated pouch, parallel to their associated tear line L, said tear line being interposed in the vertical direction between the two lines of adhesive C
Dans ce cas, on procède à l'ouverture du pochon en arrachant la partie haute des éléments de renfort 21 ' et 22' (et éventuellement le sommet liant ces éléments de renfort), ouvrant le pochon 10 lui-même dans le même tempsIn this case, the pouch is opened by tearing off the upper part of the reinforcing elements 21 ′ and 22 ′ (and possibly the top connecting these reinforcing elements), opening the pouch 10 itself at the same time
Selon l'invention, on facilite et on fiabilise ainsi le déchirement de la partie haute du pochon, en réalisant avantageusement le collage des parois du pochon et des éléments de support à la même hauteur que les lignes d'arrachage des éléments de renfort En effet, cette disposition permet de guider le déchirement du pochon à la main et de fiabiliser ainsi l'ouverture du dispositifAccording to the invention, the tearing of the upper part of the pouch is facilitated and made more reliable, by advantageously bonding the walls of the pouch and the support elements at the same height as the tear-off lines of the reinforcing elements. , this arrangement makes it possible to guide the tearing of the pouch by hand and thus to make the opening of the device more reliable.
Comme on l'a dit au début de ce texte, les pochons connus peuvent comprendre des moyens d'ouverture tels qu'une ligne de fragilisation (pouvant être réalisée par exemple par l'attaque de la feuille du pochon par un faisceau laser afin de diminuer son épaisseur)As said at the beginning of this text, the known pouches may include opening means such as a line of weakness (which can be produced for example by attacking the sheet of the pouch with a laser beam in order to decrease its thickness)
On remarquera que selon l'invention on peut simplement prévoir deux encoches situées sur les bords opposés du pochon, à la même hauteur que les lignes de fragilisation des éléments de renfort et que le collage du pochon sur ces éléments De telles encoches E sont représentées sur la figure 7b, sur laquelle on a représenté schématiquement les parties hautes de chaque élément de renfort 21 ' et 22' avec leur ligne de fragilisation L entourée de leurs deux lignes de colle CIt will be noted that according to the invention, it is possible simply to provide two notches located on the opposite edges of the pouch, at the same height as the weakening lines of the reinforcing elements and that the bonding of the pouch to these elements. Such notches E are shown on FIG. 7b, in which the upper parts of each reinforcing element 21 ′ and 22 ′ have been shown diagrammatically with their line of weakness L surrounded by their two lines of glue C
Cette disposition permet ainsi de s'affranchir d'une étape de process dans la fabrication du dispositif (telle qu'une étape d'attaque des parois du pochon par un faisceau laser), ce qui permet de réduire le prix de revient du pochonThis arrangement thus makes it possible to get rid of a process step in the manufacture of the device (such as a step of attacking the walls of the pouch by a laser beam), which reduces the cost of the pouch
Il est également à noter que les deux lignes de colle C constituent unIt should also be noted that the two lines of adhesive C constitute a
« canal » qui encadre le eu désiré de déchirement des parois du pochon et participe ainsi au guidage de ce déchirement, les deux lignes de colle constituant des obstacles aux lignes de déchirement des parois du pochon On pourra également adapter la conception du dispositif selon l'invention de sorte que des lignes d'arrachage des éléments de renfort définissant le trajet d'ouverture du dispositif soient adaptées à l'application choisie on pourra en effet avoir ainsi un trajet d'ouverture rectiligne, mais également curviligne, voire un trajet selon un motif quelconque désiré"Channel" which frames the desired tearing of the walls of the pouch and thus participates in guiding this tearing, the two lines of adhesive constituting obstacles to the tearing lines of the walls of the pouch We can also adapt the design of the device according to invention so that tear-off lines of the reinforcing elements defining the opening path of the device are adapted to the chosen application, it will indeed be possible to have a straight opening path, but also a curvilinear one, or even a path according to a any desired pattern
Il est évident que selon l'invention il est possible de solidariser chaque élément de renfort 21 , 22 et sa face de pochon associée par tout moyen connu autre qu'un collage , on pourra par exemple engager les éléments de renfort dans des aménagements (pouvant comprendre par exemple des parties de paroi du pochon dépassant des bords soudés dudit pochon et repliées sur elles-mêmes, ou encore des surépaisseurs associées à une ouverture pour le passage des éléments de renfort) des parois du pochon, ou bien souder ces éléments entre eux En référence maintenant aux figures 8a à 8e, on a représenté une forme particulière de réalisation de l'invention dans laquelle le dispositif renferme non pas un mais deux pochons 10 et 10'It is obvious that according to the invention it is possible to secure each reinforcing element 21, 22 and its associated pouch face by any known means other than bonding, it is for example possible to engage the reinforcing elements in arrangements (which can include, for example, portions of the wall of the pouch protruding from the welded edges of said pouch and folded back on themselves, or additional thicknesses associated with an opening for the passage of the reinforcing elements) of the walls of the pouch, or else weld these elements together Referring now to Figures 8a to 8e, there is shown a particular embodiment of the invention in which the device contains not one but two bags 10 and 10 '
Comme représenté en particulier sur les figures 8c et 8e, dans cette forme de réalisation de l'invention les deux pochons 10 et 10' sont collés ensemble par deux lignes de colle C qui couvrent sensiblement l'étendue latérale de la surface sur laquelle les deux pochons sont en regard l'un de l'autre On a également représenté sur les figures 8d et 8e le plan P longitudinal médian du dispositif, les pochons étant alignés sensiblement perpendiculairement à ce plan Chaque pochon est par ailleurs collé à un élément de renfort (élémentAs shown in particular in FIGS. 8c and 8e, in this embodiment of the invention the two bags 10 and 10 ′ are glued together by two lines of adhesive C which substantially cover the lateral extent of the surface on which the two pouches are opposite one another The median longitudinal plane P of the device has also been shown in FIGS. 8d and 8e, the pouches being aligned substantially perpendicular to this plane Each pouch is also glued to a reinforcing element ( element
21 ' pour le pochon 10', 22' pour le pochon 10), par deux lignes de colle C similaire à celles de la figure 7c, et qui encadrent ici encore une ligne L d'arrachage de l'élément de renfort Les éléments de renfort sont comme dans le cas du dispositif à un seul pochon disposés symétriquement par rapport au plan P (c'est à dire en regard l'un de l'autre, et à la même hauteur)21 'for the bag 10', 22 'for the bag 10), with two lines of adhesive C similar to those of FIG. 7c, and which again frame a line L tearing off the reinforcing element The reinforcing elements are as in the case of the device with a single pouch arranged symmetrically with respect to the plane P (c ' is to say opposite each other, and at the same height)
On remarquera que pour faciliter l'ouverture des pochons simultanément à l'arrachage des parties hautes des éléments de renfort 21 ' et 22', les bords latéraux des deux pochons 10 et 10' ne sont pas en regard l'un de l'autre, mais au contraire que leurs projections dans le plan longitudinal médian du dispositif sont décalées (voir en particulier les figures 8a et 8d)It will be noted that to facilitate the opening of the bags simultaneously with the tearing off of the upper parts of the reinforcing elements 21 'and 22', the lateral edges of the two bags 10 and 10 'are not opposite one another , but on the contrary that their projections in the median longitudinal plane of the device are offset (see in particular Figures 8a and 8d)
Ainsi, lors de l'ouverture du dispositif l'on attaque qu'un seul bord de pochon à la fois On pourra également prévoir des pochons de largeur différente (comme représenté sur les figures 8a et 8d en particulier) pour faciliter encore l'ouverture On notera en outre qu'ici encore les bords latéraux des pochons comportent des encoches E situées en regard des lignes d'arrachage des éléments de renfort, afin de fiabihser l'ouverture du dispositifThus, when the device is opened, only one edge of the bag is attacked at the same time. It is also possible to provide pockets of different widths (as shown in FIGS. 8a and 8d in particular) to further facilitate opening. It will also be noted that here again the lateral edges of the pouches have notches E situated opposite the tear lines of the reinforcing elements, in order to improve the opening of the device
Cette deuxième forme de réalisation permet de conditionner dans un dispositif unique des produits ayant des caractéristiques différentes On pourra par exemple dans une application de conditionnement de nourriture humaine remplir un des pochons de morceaux de viande avec ou sans sauce, tandis que l'autre pochon contenant du riz ou des légumes d'accompagnement On offre ainsi la possibilité de proposer au consommateur plusieurs produits, constituant un plat élaboré, dans un même dispositifThis second embodiment makes it possible to package in a single device products having different characteristics. For example, in a human food packaging application, it is possible to fill one of the pouches with pieces of meat with or without sauce, while the other pouch containing rice or accompanying vegetables We thus offer the possibility of offering the consumer several products, constituting an elaborate dish, in the same device
On comprend que la forme de réalisation figures 8a à 8e, qui comprend deux pochons (et qui peut également en comprendre selon cette forme de réalisation de l'invention un nombre quelconque) présente entre autres les avantages suivants • elle permet de servir en une seule fois au moins deux produits, chaque produit étant conditionné dans un pochon séparé, les deux produits pouvant avoir des caractéristiques et/ou des fonctions différentes On pourra par exemple prévoir d'intégrer dans les deux pochons respectifs des aliments ayant des goûts différents (par exemple des ravioli et du parmesan respectivement), des textures différentes (par exemple dans un premier pochon des viandes mijotées en sauce et des légumes ou des céréales cuits à la vapeur , et de manière générale des produits humides dans un pochon, et des produits secs dans l'autre pochon), voire deux fonctions différentes (un pochon pouvant contenir un aliment tel qu'un plat cuisiné complet, l'autre pochon pouvant contenir un produit tel qu'un médicament) Et de manière plus générale, les deux (ou plusieurs) pochons peuvent contenir des produits ou des composés chimiques à mélanger avant l'utilisation,We understand that the embodiment Figures 8a to 8e, which includes two bags (and which can also include according to this embodiment of the invention any number) has among others the following advantages • it allows to serve in one times at least two products, each product being packaged in a separate pouch, both products which may have different characteristics and / or functions For example, provision may be made to integrate in the two respective pouches foods having different tastes (for example ravioli and parmesan cheese respectively), different textures (for example in a first pouch of meats simmered in sauce and steamed vegetables or cereals, and generally wet products in one pouch, and dry products in the other pouch), or even two different functions (a pouch can contain a food such as a complete cooked dish, the other pouch may contain a product such as a drug) And more generally, the two (or more) pouches may contain products or chemical compounds to be mixed before use,
• en outre, chaque produit conditionné séparément dans un pochon peut garder ses caractéristiques intrinsèques avant l'ouverture des pochons et le mélange des produits respectifs qu'il contienne A cet égard, on notera qu'il est également possible de faire subir différents traitements à un pochon contenant un produit spécifique et ayant déjà été refermé (traitement de stérilisation, de conservation, ), et d'assembler ce premier pochon à un deuxième pochon n'ayant pas subi le même traitement pour constituer un dispositif tel que représenté sur les figures 8a à 8e,• in addition, each product packaged separately in a pouch can keep its intrinsic characteristics before the opening of the pouches and the mixing of the respective products it contains. In this regard, it should be noted that it is also possible to subject different treatments to a pouch containing a specific product and having already been closed (sterilization treatment, conservation,), and to assemble this first pouch to a second pouch which has not undergone the same treatment to constitute a device as shown in the figures 8a to 8e,
• un tel dispositif est également pratique car il permet d'ouvrir les différents pochons qu'il comprend en une seule fois (et de ce point de vue le décalage des extrémités des bords latéraux du pochon est particulièrement avantageux),Such a device is also practical because it makes it possible to open the various pouches which it comprises at one time (and from this point of view the offset of the ends of the lateral edges of the pouch is particularly advantageous),
• ce dispositif présente également un haut degré de sécurité, car il permet au fabricant d'intégrer aux différents pochons les quantités exactes de produit devant être mélangées ensemble, et d'adapter ces quantités en fonction des lots de pochon à associer, • enfin, un tel dispositif est également avantageux en terme de présentation car il permet de verser dans un même récipient les produits respectifs contenus dans les pochons respectifs côte à côte si l'on décide de verser ces produits par le bord latéral des pochons, et il est également possible de verser ces produits en formant dans les récipients recevant le contenu des pochons des couches superposées en déversant au contraire les produits par le milieu des faces latérales pochons superposésThis device also has a high degree of security, since it allows the manufacturer to integrate the exact quantities of product to be mixed together into the various pouches, and to adapt these quantities as a function of the batches of pouch to be combined, Finally, such a device is also advantageous in terms of presentation because it makes it possible to pour into the same container the respective products contained in the respective pouches side by side if it is decided to pour these products by the lateral edge of the pouches, and it is also possible to pour these products by forming superimposed layers in the containers receiving the pouches of the layers, on the contrary pouring the products through the middle of the side faces
Il est ainsi possible selon l'ouverture de prévoir un nombre quelconque de pochons alignés en série et collés entre eux deux à deux par leurs parois adjacentes, de préférence à la même hauteur que des encoches de leurs bords latéraux, entourés de deux éléments de renfort également collés (ou solidarisés aux pochons par tout autre moyen connu), les éléments de renfort pouvant comporter des lignes d'arrachage Les éléments de renfort peuvent également dans ce cas ne pas comporter de lignes d'arrachage, les pochons pouvant alors être munis de moyens d'ouverture tels que des lignes de fragilisation réalisée par une attaque laserIt is thus possible, depending on the opening, to provide any number of bags aligned in series and glued together in pairs by their adjacent walls, preferably at the same height as notches in their lateral edges, surrounded by two reinforcing elements. also bonded (or secured to the pouches by any other known means), the reinforcing elements may include tearing lines The reinforcing elements may also in this case not have tearing lines, the pouches can then be provided with opening means such as weakening lines produced by a laser attack
Bien entendu, les caractéristiques décrites en référence aux figures 1a à 6d (dispositifs comportant un seul pochon) sont également applicables aux dispositifs à deux ou plusieurs pochons bords latéraux des éléments de renfort assemblés ou disjoints, fond et/ou sommet pour joindre les deux éléments de renfort, languette de fermeture Of course, the characteristics described with reference to FIGS. 1a to 6d (devices comprising a single pouch) are also applicable to devices with two or more pouches lateral edges of the assembled or disjointed reinforcing elements, bottom and / or top to join the two elements reinforcement, closing tab
