ABSTRACT:
A method and system for transferring a flowable material from a container to a receiver through a flexible tubing which communicates with an opening defined in the container and which extends outwardly from the container. The method involves establishing within the container, after discharge of the material therefrom, a pressure less than the ambient pressure so as to draw the tubing into the container through the opening as a result of the pressure differential created between that within the container and the ambient pressure.
