The invention concerns a bag with lateral folds made from a multilayer
flexible film whereof the inner layer is sealable, said bag comprising a
closed bottom end and a top end provided with a closure system, and lateral
folds (3, 4) arranged on both sides between the two side walls of the bag
which form the front wall (1) and the rear wall (2) of the bag, said lateral
folds extending from the bottom end to the top end, and terminating spaced
apart from the top marginal edges (5) of the walls (1, 2) of the bag.
According to the invention, the bag walls are bonded with the lateral folds
and in the top part of the bag, not containing any lateral fold, one beneath
the other along their marginal edges, and the top end parts (12) of the
lateral folds, are folded towards the bag wall, relative to a folding line
(13) which is inclined inwards and downwards towards the bottom end, the
folded end parts are bonded at their inner side, with the inner side of the
halves of neighbouring lateral folds, and closed at the marginal edges on the
top side (17). The invention is characterized in that the folded end parts of
the lateral folds, are surface-bonded at their outer side, with the
neighbouring bag wall, one part of the halves of the lateral folds, which is
adjacent the folded end parts of the lateral folds, is also surface-bonded to
the neighbouring bag wall, and the bonding link (14, 15, 16) encompasses the
marginal edges of the folded end parts of the lateral folds.
La présente invention concerne un sac à pliures latérales réalisé à partir d'un film flexible multicouche dont la couche intérieure est soudable, ledit sac comprenant une extrémité de fond fermée et une extrémité de tête dotée d'un système de fermeture, et des pliures latérales (3;4) disposées des deux côtés entre les deux parois latérales de sac qui forment la paroi avant (1) et la paroi arrière (2) du sac, lesdites pliures latérales s'étendant de l'extrémité de fond à l'extrémité de tête, et se terminant à distance en-dessous des arêtes marginales supérieures (5) des parois (1, 2) du sac. Selon l'invention, les parois de sac sont soudées avec les pliures latérales et dans le partie tête du sac, dépourvue de pliure latérale, l'une en-dessous de l'autre le long de leurs arêtes marginales, et les parties d'extrémité supérieures (12) des pliures latérales, sont repliées vers une paroi du sac, par rapport à une ligne de pliure (13) qui est inclinée vers l'intérieur et vers le bas vers l'extrémité de fond, les parties d'extrémité repliées sont soudées au niveau de leur côté intérieur, avec le côté intérieur des moitiés de pliures latérales voisines, et refermées au niveau des arêtes marginales côté tête (17). L'invention se caractérise en ce que les parties d'extrémité repliées des pliures latérales, sont soudées en surface au niveau de leur côté extérieur, avec la paroi de sac voisine, une partie (16) des moitiés de pliures latérales, qui est adjacente aux parties d'extrémité repliées des pliures latérales, est également soudée en surface à la paroi de sac voisine, et la liaison de soudure (14, 15, 16) englobe les bords marginaux des parties d'extrémité repliées des pliures latérales.
