A bag (10) having a flap valve (20, 22) beneath an opening at the top edge and a second valve (32) including a longitudinally slidable valve member (34) having a downwardly extending tube (40). When the slidable valve (34) is in the open position the downwardly extending tube (40) passes through the flap valve (20, 22) to provide sterile access to the liquid within the bag (10). |
