ABSTRACT:
A closable bag of flexible material is provided with a separate inlet member (3) with an opening for filling the bag with a substance, for instance liquid, which inlet member is fastened to the bag. A separate member (7) is arranged for closing the filling opening from inside the bag. The closing member (7) for its closing of the filling opening is arranged for releasable sealing engagement with the inlet member (3), thereby enabling a subsequent partial discharge and reclosing of the bag. The separate inlet and closing members (3, 7) are substantially resistant to deformation and have means (6, 12) for engagement by respective elements of an operating equipment (13-16) arranged outside the bag. The operating equipment includes a filling member connectable to the inlet member, and means for sterilizing a space formed between the filling and closing members.
