Abstract A closable bag of flexible material, said bag having a separate inlet member with an opening for filling the bag with a material, for instance a liquid, with the inlet member being fastened to the bag. A separate member is arranged to close the filling opening from the inside of the bag. The closing member for closing the filling opening is arranged for releasable sealing engagement with the inlet member, thereby enabling the subsequent partial discharge and reclosing of the bag. Furthermore, the separate inlet and closing members are substantially resistant to deformation and both have means for engagement by apparatus located outside the bag, to open and close the filling opening as required. The bag is filled by placing the bag, while sterilized and closed, in an operating equipment, engaging parts of the operating equipment with both the inlet member and the closing member, connecting the inlet member to a filling member of the equipment while forming a space between the filling member and the closing member and sterilizing the space with a fluid such as steam while keeping the filling opening closed. The equipment is then operated to separate the inlet member from the closing member and thereby uncover the filling opening, the bag is filled with substance from the filling member, the equipment is then operated to bring the inlet member and closing member together and thereby close the filling opening, the inlet member is separated from the filling member, and the filled bag is removed from the operating equipment.
