ABSTRACT:
A liquid transfer assembly comprises a drug container and a syringe. The container has a bag of a flexible polymer with spines forming channels internally of the bag. The container is closed by a valve which has a valve member that is urged outwardly to a closed position by a helical spring. A luer taper bore in the valve is engaged by the nose of the syringe which, when inserted, depresses the valve member and opens the valve. Withdrawing the plunger of the syringe causes liquid drug in the bag to be sucked through the valve into the syringe and the bag to collapse about the remaining contents. The valve reseals the remaining contents on withdrawal of the syringe.
