The invention relates to a bag comprising side gussets (1a) which extend along only part of the height thereof, such as to form walls (1b1), (1c1) at a certain distance (a) from the opening of the bag, which can be assembled directly to one another along the side edges thereof. The upper end of the gussets is closed by means of an external fold area which is folded at 45° such as to define an essentially-triangular shape (1a4) that is disposed between the two folds of the gussets.
Le sac présente des soufflets latéraux (1a) sur une partie de sa hauteur seulement, de manière à laisser subsister, à une certaine distance (a) de l'ouverture du sac, des parties de parois (1b1), (1c1) aptes à être assemblées directement l'une sur l'autre, au niveau de leurs bords latéraux. L'extrémité supérieure des soufflets est fermée par une zone de pliage externe à 45~ délimitant, une forme sensiblement triangulaire (1a4) disposée entre les deux plis des soufflets.
