A container (10) for fluids or liquids such as beverages and the like i s formed of flexible material such as plastic and includes a body (12) having an internal reservoir (14) and a tubular spout (30) extending upwardly from the body. The spout has an internal passage (32) in fluid communication with the reservoir. A constriction (34) in the container creates a low pressure zone in the passage downstream of the constriction as liquid flows from the reservoi r into the spout. Means are also provided to inflate the spout as fluid flows along the internal passage. A method of forming fluid-filled containers from a tub e (58) of flexible material and a method of forming a self-supporting fluid- filled container are also disclosed.
