Abstract

Le sac comprend une paroi avant (1a) et une paroi arrière (1b) assemblées, au niveau de leurs côtés latéraux, en combinaison avec des soufflets (1e) et (1d) formant deux plis, et au niveau de l'un de leur côté transversal avec ledit soufflet, pour former un fond (le). Selon l'invention, les bords latéraux extérieurs des soufflets sont raccordés au fond par des lignes de coupe obliques, de sorte qu'après remplissage du sac correspondant à l'écartement des soufflets (1e) et (1d), lesdites lignes obliques forment symétriquement, de part et d'autre du fond (le), un dégagement en triangle (T), sans surépaisseur, améliorant ainsi la stabilité dudit sac, en position verticale de remplissage.The bag comprises a front wall (1a) and a rear wall (1b) assembled, at their lateral sides, in combination with gussets (1e) and (1d) forming two folds, and at one of their transverse side with said bellows, to form a bottom (the). According to the invention, the outer lateral edges of the bellows are connected to the bottom by oblique cut lines, so that after filling the bag corresponding to the spacing of the bellows (1e) and (1d), said oblique lines form symmetrically , on either side of the bottom (the), a triangular clearance (T), without extra thickness, thus improving the stability of said bag, in the vertical filling position.
