Abstract
A bag is provided for containing a liquid intended to be supplied in a controlled manner to some other site, for example to a medical patient. The main bag portion has a pair of overlying side walls joined together around their edges, the side walls having integral extensions which together define an outlet region in communication with the interior of the main portion of the bag. The extensions are bonded together to define a tube-like passageway extending throughout the outlet region from the interior of the bag. The extensions are adapted to permit the connection thereto of a peristaltic pump device co-operable with the tube-like passageway to control the out-flow of liquid from the bag.
