A flexible package for storing and transporting bulk goods. Such flexible package can have material-impermeable connections for spreading out sections of the flexible package wall so as to correspond to a predefined shape. One or more docking connections for filling and discharging can be included. The flexible package can have a square bottom and adjacent to the sides thereof triangular stubs as lateral walls. Together, such lateral walls can form an upwardly open pyramid shape. Opposite the bottom, a coupling element can be connected in such a manner that it presents the flexible package so as to be sealable in a standardized manner on open-sided ends of the lateral walls.
