Description de modes de realisation de ['invention Description of embodiments of the invention
La figure 1 montre un emballage sous la forme d'un sachet ou d'un sac, notamment d'un sachet ou d'un sac a soufflets de forme es s sentiellement rectangulaire dans la position representee. L'emballage peut avoir un fond approprie de forme quelconque, par exemple un fond plat forme par des soudures transversales ou encore un fond mis en forme obtenu par des pliages comme par exemple un fond en forme de bloc ou un fond croise. L'extremite superieure presente une piece de fermeture to quelconque, appropriee, realisee de fagon analogue au fond mais qui a la place d'une soudure transversale ou d'une soudure de fermeture comporte Figure 1 shows a package in the form of a sachet or a bag, in particular a sachet or a bellows bag of substantially rectangular shape in the position shown. The packaging may have an appropriate bottom of any shape, for example a flat bottom formed by transverse welds or else a shaped bottom obtained by bending such as for example a block-shaped bottom or a crossed bottom. The upper end has any suitable closure piece to, made similarly to the bottom but which instead of a transverse weld or a closing weld has

La forme quadrangulaire peut avoir comme represente une section de rectangle ou d'un carre. Les parois laterales 1, 2, 3, 4 repre s sentees, font partie, comme cela apparat aux figures 5 et 7, d'un segment de film, relic, dont le chte qui constitue le futur cote interieur de ltemballage est muni d'applications de colle avant que l'on effectue les ope The quadrangular shape can be represented by a rectangle or a square section. The side walls 1, 2, 3, 4 repre sented, are part, as it appears in Figures 5 and 7, of a film segment, relic, whose frame which constitutes the future inner side of the packaging is provided with glue applications before the operations are carried out
rations de confection.clothing rations.
L'emballage represente a la figure 1 est muni d'une zone de bord longitudinal renforcee 6, 7, 8 au niveau du passage entre les parois laterales respectives 1, 2, 3, 4; ces zones de bord longitudinal renforcees comportent des zones partielles en forme de bandes 10, 11 (figures 3, 4) des parois laterales qui se superposent en formant un pli 12 en U et qui vent reliees entre elles a pleine surface ou par zones, par des zones de s surfaces de collage discretes, en ligne, constituees par un adhesif 14. Pour relier les zones partielles 10, 11 des parois laterales 1, 2, 3, 4 formees d'un film en matiere plastique ou d'un film composite avec une couche interieure de matiere plastique, on utilise comme colle de preference une The packaging shown in FIG. 1 is provided with a reinforced longitudinal edge zone 6, 7, 8 at the level of the passage between the respective lateral walls 1, 2, 3, 4; these reinforced longitudinal edge zones comprise partial zones in the form of bands 10, 11 (FIGS. 3, 4) of the lateral walls which are superimposed by forming a fold 12 in U and which are connected to each other at full surface or by zones, by zones of discrete bonding surfaces, in line, formed by an adhesive 14. To connect the partial zones 10, 11 of the side walls 1, 2, 3, 4 formed by a plastic film or a composite film with an inner layer of plastic, preferably used as glue
colle a chaud, notamment a base de polyurethane. hot glue, especially based on polyurethane.
so Selon les figures 5 et 7, le segment de film plat 5 comporte une bande de liaison 13 qui, lorsque ltemballage est "ermine, chevauche la paroi laterale 1 et est reliee a celle-ci par un cordon de fermeture 15 don nant au segment de film plat 5 la structure d'une gaine. Le cordon de fer meture 15 est habituellement un cordon de soudure ou de scellement ss s'etendant parallelement aux zones de bord longitudinal 6, 7, 8, 9 dans la n / a According to FIGS. 5 and 7, the flat film segment 5 comprises a connecting strip 13 which, when the packaging is "closed", overlaps the side wall 1 and is connected to the latter by a closure cord 15 giving rise to the segment of flat film 5 the structure of a sheath. The metal bead 15 is usually a weld or sealing bead extending parallel to the longitudinal edge zones 6, 7, 8, 9 in the
direction longitudinale sur toute la longueur de l'emballage. longitudinal direction over the entire length of the package.
L'agent adhesif 14 pour realiser le collage peut etre prevu uniquement sur l'une des deux bandes 10, 11 des parois laterales 1, 2, 3, 4 formant les plis 12 en U. Toutefois, de maniere preferentielle, on prevoit une application d'adhesif 16, 17 sur les deux bandes de film 1O, 11 qui constituent le pli 12 en U. Dans la realisation selon la figure 5, les deux applications d'adhesif 16, 17 en forme de bande, rejoignent directement s l'arete de pliage 18 des plis 12 en forme de U comme le montre la figure 6 The adhesive agent 14 for bonding can be provided only on one of the two strips 10, 11 of the side walls 1, 2, 3, 4 forming the folds 12 in U. However, preferably, an application is provided of adhesive 16, 17 on the two strips of film 10, 11 which constitute the fold 12 in U. In the embodiment according to FIG. 5, the two applications of adhesive 16, 17 in the form of a strip, join directly with the folding edge 18 of the folds 12 in a U shape as shown in FIG. 6
et comme cela apparat dans les modes de realisation des figures 1 et 3. and as it appears in the embodiments of Figures 1 and 3.
Dans le cas des figures 7 et 8, les applications d'adhesif 16, 17 restent a une certaine distance de l'arete de pliage 18 des plis 12 en forme de U comme cela appara^t a la figure 4. Une telle realisation facilite ltobtention In the case of FIGS. 7 and 8, the applications of adhesive 16, 17 remain at a certain distance from the folding edge 18 of the folds 12 in the shape of a U as appears in FIG. 4. Such an embodiment facilitates obtaining
o d'aretes de pliage vives lorequ'on effectue le pliage. o sharp folding edges when folding is carried out.
Les applications d'adhesif 16, 17 vent prevues uniquement dans chaque segment longitudinal des parois laterales 1, 2, 3, 4 qui est Adhesive applications 16, 17 are planned only in each longitudinal segment of the side walls 1, 2, 3, 4 which is
lateralement adjacent lorsqu'on remplit l'emballage de la matiere de rem- laterally adjacent when filling the packaging with the filling material
plissage. Ainsi, les zones de la partie superieure et du fond de ltemballage s peuvent etre confectionnees sans difficulte avec des applications d'adhesif pleating. Thus, the areas of the upper part and of the bottom of the packaging can be made without difficulty with adhesive applications.
16, 17 jusqu'a un fond ou une piece de fermeture. 16, 17 to a bottom or a closing piece.
A la place d'applications d'adhesif 16, 17 en forme de bande, continue, on peut egalement appliquer l'adhesif 14 dans des zones discretes d'adhesif prevues dans une rangee a l'interieur de la zone 10, 11 Instead of adhesive applications 16, 17 in the form of a continuous strip, it is also possible to apply the adhesive 14 in discrete zones of adhesive provided in a row inside the zone 10, 11
o formant les plis 12 en U des parois laterales 1, 2, 3, 4. o forming the folds 12 in U of the side walls 1, 2, 3, 4.
