Abstract
Fuel gas or some other kind of fluid is stored in a collapsible metallic bag that is attached to a valve and is stored inside a rigid outer container. Between the rigid outer container and the collapsible bag is a space or volume filled with compression gas during use which puts a collapsing pressure evenly upon the bag. In order to reduce bag failures, the outer surface of the collapsible bag has a series of projected streak portions that project outwardly from the vertical length of the collapsing in several locations that prevent the bag from expanding to fill the entire space between the rigid outer container and the bag. These projected streaks form recessed portions in the bag's surface which facilitates the bag collapsing in those predetermined locations evenly which in turn reduces the collapsible bag's failure rate from breaking during operation.
