Abstract
To empty a bag which has at least one cross bottom (4) which is covered with a bottom cover sheet (18) and which has an essentially rectangular shape and is glued together out of corner tucks (11) angled from narrow sidewalls via folding lines and out of bottom flaps (12) angled from wide sidewalls via folding lines (13, 14), there is provision, according to the invention, whereby the bottom cover sheet (18) is drawn off, starting from a narrow sidewall, from the respective corner tuck (11) and from part of the adjoining bottom flaps (12), whereby the bottom flaps (12) are torn on the far side of the corner tuck, transversely with respect to their free edges, as far as the adjoining wide sidewall, in order to separate a part (12′) of the bottom flaps (12), and whereby the separated parts (12′) of the bottom flaps (12), together with the corner tuck (11), are bent, by being folded up about the folding lines (13, 14, 23), into a pour-out channel (24), via which the emptying of the bag contents takes place.
