The invention relates to a bag comprising side gussets ( 1 a) which extend along only part of the height thereof, such as to form walls ( 1 b 1 ), ( 1 c 1 ) 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 ( 1 a 4 ) that is disposed between the two folds of the gussets. |
