Abstract
A helical coil winding inserted in a flexible bag, such as a plastic bag, and connected to or associated with the dispensing spout or neck opening thereof. The helical coil will extend into the bag and will provide a form, about which the flexible wall of the bag will collapse and form, to provide a dispensing tube or passageway leading to the bag spout, as the contents of the bag are removed as a result of a pumping action, suction action or other condition resulting in differential pressure causing collapse of the bag.
