Description

La présente invention a pour objet un perfectionnement aux sachets en matière synthetique souple objet de la revendication 1 de la demande principale 85-03100 à laquelle le present certificat d'addition est rattaché. The present invention relates to an improvement to sachets in flexible synthetic material which is the subject of claim 1 of main application 85-03100 to which this certificate of addition is attached.

Selon celle-ci on propose un sachet en matière synthétique souple du type obtenu à partir d'au moins une bande de film de matière synthétique conforme de manière à déterminer par des soudures un fond sur lequel repose le sachet, deux parois latérales, une zone de rigidification et de préhension reliant les deux parois latérales et une face frontale reliant egalement les deux parois latérales, ladite face frontale correspondant au côté où s'opère le versage du contenu du sachet après ouverture de celui-ci, la face frontale étant en outre munie d'un moyen de rigidification et de stabilisation du sachet. According to this, a flexible plastic bag of the type obtained from at least one strip of plastic film conforming is proposed so as to determine by soldering a bottom on which the bag rests, two side walls, an area stiffening and gripping connecting the two side walls and a front face also connecting the two side walls, said front face corresponding to the side where the pouring of the contents of the sachet takes place after opening thereof, the front face also being provided with a means of stiffening and stabilizing the bag.

On propose aux revendications 2 et -9 des structures spécifiques pour ledit moyen de rigidification et de stabilisation qui peut affecter la forme d'un contrefort ou de une ou plusieurs nervures. Specific structures are proposed in claims 2 and -9 for said stiffening and stabilization means which can affect the shape of a buttress or one or more ribs.

Le présent certificat d'addition a pour objet de decrire de nouveaux modes de mise en oeuvre ainsi que des procédés pour leur mise en oeuvre et des dispositifs pour leur obtention. The purpose of this certificate of addition is to describe new modes of implementation as well as methods for their implementation and devices for obtaining them.

Conformement à la presente demande, on prévoit un sachet en matiere synthétique souple du type obtenu à partir d'au moins une bande de film de matière synthétique conformée de manière à déterminer par des soudures un fond sur lequel repose le sachet, deux parois latérales, une zone de rigidification et de préhension reliant les deux parois latérales et une face frontale reliant également les deux parois laterales, ladite face frontale correspondant au côte ou s'opère le versage du contenu du sachet après ouverture de celui-ci et étant munie d'un moyen de rigidification et de stabilisation du sachet, caractérisé en ce que le moyen de rigidification et de stabilisation est réalise par formation de plis sur les arêtes frontales du sachet ou par apport d'eléments rigidifiants ou structurants sur lesdites arêtes. In accordance with the present application, a flexible plastic bag of the type obtained from at least one strip of plastic film conformed is provided so as to determine by soldering a bottom on which the bag rests, two side walls, a stiffening and gripping zone connecting the two side walls and a front face also connecting the two side walls, said front face corresponding to the side where the contents of the bag are poured after opening thereof and being provided with a means of stiffening and stabilizing the bag, characterized in that the means of stiffening and stabilizing is produced by forming folds on the front edges of the bag or by providing stiffening or structuring elements on said edges.

La ri gi di fi cati on pourra donc être obtenue par deux moyens essentiels
- modification de la structure du film,
- apport d'élement formant surepaisseur, donc rigidification.The ri gi di fi cati can therefore be obtained by two essential means
- modification of the structure of the film,
- addition of element forming extra thickness, therefore stiffening.

Ces deux moyens pourront être appliqués ou mis en oeuvre à l'intérieur ou à l'extérieur du sachet. These two means can be applied or implemented inside or outside the sachet.

On comprendra mieux l'invention à l'aide de la description ci-après d'un certain nombre de modes de mise en oeuvre, en référence aux dessins annexes dans lesquels
- la figure 1 est une vue en perspective d'un sachet conforme à l'invention,
- les figures 2 à 10 illustrent de manière schématique divers modes de mise en oeuvre permettant d'obtenir la rigidification désirée aux niveaux des arêtes frontales du sachet
- la figure 11 est une vue schématique d'un dispositif pour l'obtention des sachets de l'invention
- la figure 12 est une vue schematique en coupe illustrant un mode particulier de mise en oeuvre du dispositif de la figure 11 correspondant au sachet de la figure 2.The invention will be better understood with the aid of the description below of a certain number of modes of implementation, with reference to the accompanying drawings in which
FIG. 1 is a perspective view of a bag according to the invention,
- Figures 2 to 10 schematically illustrate various modes of implementation to obtain the desired stiffening at the front edges of the bag
- Figure 11 is a schematic view of a device for obtaining the bags of the invention
FIG. 12 is a schematic sectional view illustrating a particular embodiment of the device of FIG. 11 corresponding to the bag of FIG. 2.

On se réferera tout d'abord à la figure 1. Le sachet (101) conforme à l'invention comporte sur sa face frontale (102) deux arêtes (103, 104) qui sont rigidifiées pour conférer au sachet stabilité et forme. We will first refer to Figure 1. The bag (101) according to the invention has on its front face (102) two edges (103, 104) which are stiffened to give the bag stability and shape.

Ce résultat est obtenu, soit par formation de plis, soit par apport d'éléments rigidifiants ou structurants au niveau desdites arêtes. This result is obtained either by the formation of folds or by the addition of stiffening or structuring elements at the level of said edges.

Ces éléments sont rapportes en surface sur la gaine formant le sachet par collage, scellage, soudage ou tout autre procédé adéquat. These elements are attached to the surface on the sheath forming the bag by gluing, sealing, welding or any other suitable process.

Comme il sera illustré ultérieurement, lesdits éléments seront monomatière ou composites, plats ou anguleux, etc...  As will be illustrated later, said elements will be single or composite, flat or angular, etc.

Ainsi on a représente à la figure 2 un renfort (105) rapporte extérieurement au sachet et -formant un angle dont le sommet marque l'arête du sachet. C'est la réalisation la plus élémentaire conforme à l'invention. L'angle d'ouverture du renfort (105) peut être quelconque. On peut envisager êgalement de lui conferer une certaine élasticité pour que l'angle reste bien marque même lorsque le sachet est complêtement rempli. Thus we have shown in Figure 2 a reinforcement (105) relates externally to the bag and -forming an angle whose top marks the edge of the bag. It is the most basic embodiment according to the invention. The opening angle of the reinforcement (105) can be arbitrary. We can also consider giving it a certain elasticity so that the angle remains well marked even when the sachet is completely filled.

On a represente à la figure 3 une structure analogue avec renfort extérieur (106), qui est applique sur l'arête en enveloppant un insert (107) dispose parallélement à ladite arête. L'insert peut être réalise en toute matière. FIG. 3 shows a similar structure with external reinforcement (106), which is applied to the edge by enveloping an insert (107) arranged parallel to said edge. The insert can be made of any material.

Dans la réalisation de la figure 4, le renfort (108) est obtenu par pincement de l'arête du sachet, comme illustré dans le brevet principal. In the embodiment of Figure 4, the reinforcement (108) is obtained by pinching the edge of the bag, as illustrated in the main patent.

A la figure 5, le même résultat est obtenu en rapportant un cordon (109) le long de l'arête.  In FIG. 5, the same result is obtained by fitting a bead (109) along the edge.

A la figure 6, l'arête est marquée le long du bord d'une bandelette de renforcement (110). In Figure 6, the edge is marked along the edge of a reinforcing strip (110).

A la figure 7, l'angle du renfort exterieur (111) est pincé, ce qui accentue le marquage de l'arête. In FIG. 7, the angle of the external reinforcement (111) is pinched, which accentuates the marking of the edge.

Enfin la réalisation representée à la figure 8 montre un renfort extérieur (112) replié sur lui-meme, déterminant une cavité longitudinale (113) qui peut etre vide ou gonflée, accentuant ainsi la rigidification. Finally, the embodiment shown in FIG. 8 shows an external reinforcement (112) folded back on itself, determining a longitudinal cavity (113) which can be empty or inflated, thus accentuating the stiffening.

Dans les modes de réalisation illustres aux figures 9 et 10, c'est le film .constituant le sachet qui est affaibli, soit interieurement (114) soit extérieurement (115). In the embodiments illustrated in FIGS. 9 and 10, it is the film constituting the sachet which is weakened, either internally (114) or externally (115).

Le pliage peut être obtenu dans ce cas par poinçonnage à chaud ou à froid. Folding can be obtained in this case by hot or cold punching.

On se référera maintenant aux figures 11 et 12 qui illustrent un dispositif permettant d'obtenir les réalisations des figures 2 à 8. Reference will now be made to FIGS. 11 and 12 which illustrate a device making it possible to obtain the embodiments of FIGS. 2 to 8.

La pose de l'élément de rigidification se fera de préférence lorsque le film sera conforme à partir d'une gaine sur un conformateur préfigurant la forme et les dimensions de l'emballage termine. Un système d'alimentation acheminera l'élément de rigidification qui sera apposé au niveau du conformateur sur la gaine du film. The laying of the stiffening element will preferably be done when the film is conforming from a sheath on a conformator foreshadowing the shape and dimensions of the finished packaging. A feeding system will convey the stiffening element which will be affixed at the level of the shaper on the film sheath.

Ainsi, les sachets conformes à l'invention sont obtenus à partir d'une gaine (116) qui passe sur une matrice (117). Cette matrice comporte, pour former les arêtes frontales, un ou plusieurs conformateurs (118). Thus, the bags according to the invention are obtained from a sheath (116) which passes over a matrix (117). This matrix comprises, to form the front edges, one or more conformers (118).

Au niveau du conformateur (118), on applique par soudure, collage ou scellage l'élément de rigidification (119) à partir d'une bobine d'alimentation (120), au moyen d'un dispositif adéquat (121) dont la nature est liée au mode de fixation, à savoir soudure, collage ou scellage. Le dispositif (121) comportera par exemple une tête (122) de profil complémentaire à celui du conformateur (118). At the level of the shaper (118), the stiffening element (119) is applied by welding, gluing or sealing from a supply coil (120), by means of a suitable device (121) whose nature is linked to the method of attachment, namely welding, gluing or sealing. The device (121) will for example include a head (122) of profile complementary to that of the shaper (118).

Le système fonctionnera de manière alternative, c'est-à-dire que lorsqu'un sachet est en cours de remplissage, l'avance du film est arrêtee et le dispositif applique un élément de rigidification sur un sachet en cours de conformation. The system will operate in an alternative manner, that is to say that when a sachet is being filled, the advance of the film is stopped and the device applies a stiffening element to a sachet being shaped.

L'élément de rigidification sera découpe automatiquement avant ou pendant la pose à la longueur nécessaire, par exemple la longueur de l'arête correspondant au sachet rempli et fermé. The stiffening element will be cut automatically before or during installation to the necessary length, for example the length of the edge corresponding to the filled and closed bag.

Selon une variante de mise en oeuvre de ltinvention, on prévoiera également de renforcer les arêtes supérieures du du sachet, comme représente par la référence (123). La structure de ce renfort horizontal sera identique à celle illustrée aux figures 2 à 10 pour le renfort vertical. According to a variant implementation of the invention, provision will also be made to reinforce the upper edges of the sachet, as represented by the reference (123). The structure of this horizontal reinforcement will be identical to that illustrated in FIGS. 2 to 10 for the vertical reinforcement.

La pose en sera opérée comme illustré à la figure 11, à partir d'une alimentation (124) et selon un mode operatoire totalement analogue à celui decrit précédemment pour le renfort vertical. The installation will be carried out as illustrated in FIG. 11, from a power supply (124) and according to an operating mode completely similar to that described above for the vertical reinforcement.

On comprendra que l'invention s'applique à tous les modes de mise en oeuvre, indépendamment en particulier de la nature des matériaux utilisés.  It will be understood that the invention applies to all modes of implementation, regardless in particular of the nature of the materials used.
